Real-world data on the management of pazopanib-induced liver toxicity in routine care of renal cell cancer and soft tissue sarcoma patients. Cancer Chemother Pharmacol 2024; 93:353-364. [PMID: 38104304 PMCID: PMC10951019 DOI: 10.1007/s00280-023-04615-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 11/03/2023] [Indexed: 12/19/2023]
Abstract
PURPOSE Pazopanib is known to cause liver toxicity. A relationship between pazopanib exposure and alanine transaminase elevations has been described in clinical trials. This study investigated the relation between pazopanib exposure and liver toxicity in real-world patients and evaluated the management of pazopanib-induced liver toxicity in routine care. METHODS A retrospective observational cohort study was performed in patients treated with pazopanib in whom pazopanib exposure was measured. The percentage of patients with and without liver toxicity during treatment with pazopanib was calculated as well as the average pazopanib exposure in both groups. Furthermore, the management of patients with liver toxicity was evaluated. RESULTS Liver toxicity was observed in 25 out of the 133 patients included (19%). Pazopanib exposure was comparable in patients with or without liver toxicity (27.7 mg/L versus 28.1 mg/L). Seven patients permanently discontinued pazopanib after the occurrence of liver toxicity. Of the remaining 18 patients, continuation or restart of pazopanib after liver toxicity was successful in 16 patients and half of these patients were able to safely continue pazopanib at the same dose as prior to liver toxicity for the remaining duration of treatment. CONCLUSION Our study did not demonstrate a clear relationship between pazopanib exposure and the occurrence of pazopanib-induced liver toxicity. Half of the patients were able to safely continue or restart pazopanib treatment after liver toxicity and received the same dose as prior to drug withdrawal. Successful interventions to address pazopanib-induced toxicity in the clinic led to an algorithm for the management of pazopanib-induced liver toxicity.

Real-World Treatment Patterns and Effectiveness of Patients With Advanced Renal Cell Carcinoma: A Nationwide Observational Study. Clin Genitourin Cancer 2024; 22:295-304.e6. [PMID: 38105152 DOI: 10.1016/j.clgc.2023.11.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 11/16/2023] [Accepted: 11/19/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Treatment landscape for advanced renal cell carcinoma (aRCC) has evolved quickly and few data about the real-world treatment patterns are available. This study aimed at describing the real-world treatment patterns and effectiveness of all systemic treatments available for aRCC in first and second-line treatment. MATERIALS AND METHODS A cohort of patients initiating a first-line systemic treatment for aRCC in 2016 was extracted from the French nationwide healthcare insurance system database (SNDS). The first-line treatment initiation date constituted the index date and patients were followed until death, loss to follow-up, or December 31, 2019, whichever occurred first. aRCC was identified using hospital diagnosis, long-term disease, or renal biopsy before index date. All analyses were performed for first and second-line treatment. Overall survival (OS) and time-to-next treatment or death (TNT-D) were estimated using Kaplan-Meier approach. RESULTS In 2016, 1629 patients initiated a first-line treatment for aRCC. Most of them were male (75.9%) and the median age was 67 years. Most of patients (91.7%) had received a tyrosine kinase inhibitor as first-line treatment, mainly sunitinib (64.4%), and 53.5% received a second-line, among which 43.7% nivolumab. Median OS (95% confidence interval [CI]) was 20.7 (95% CI:18.2-22.4) months from first-line treatment initiation and 15.4 (13.9-17.5) months from second-line treatment initiation. Median TNT-D were respectively 9.3 (9.7-12.1) months and 6.9 (5.9-7.7) months. CONCLUSION This study highlights the limited survival of aRCC patients These results provide a valuable baseline and highlight the need for innovation, such as immune checkpoint inhibitor-based combinations that have recently became first-line standard of care.

Abstract
The precision oncology paradigm challenges the feasibility and data generalizability of traditional clinical trials. Consequently, an unmet need exists for practical approaches to test many subgroups, evaluate real-world drug value, and gather comprehensive, accessible datasets to validate novel biomarkers. Real-world data (RWD) are increasingly recognized to have the potential to fill this gap in research methodology. Established applications of RWD include informing disease epidemiology, pharmacovigilance, and healthcare quality assessment. Currently, concerns regarding RWD quality and comprehensiveness, privacy, and biases hamper their broader application. Nonetheless, RWD may play a pivotal role in supplementing clinical trials, enabling conditional reimbursement and accelerated drug access, and innovating trial conduct. Moreover, purpose-built RWD repositories may support the extension or refinement of drug indications and facilitate the discovery and validation of new biomarkers. This perspective explores the potential of leveraging RWD to advance oncology, highlights its benefits and challenges, and suggests a path forward in this evolving field.

Abstract
The efficacy-effectiveness (EE) gap describes the differences in survival seen in clinical trials and routine clinical practice, where patients in real-world practice often have inferior outcomes compared to trial populations. However, EE gaps may exist beyond survival outcomes, including gaps in quality of life, toxicity, cost-effectiveness, and patient time, and these EE gaps should also influence patient and clinician treatment decisions. Failure to clearly acknowledge these EE gaps may cause patients, clinicians, and health care systems to have unrealistic expectations of the benefits of therapy across a range of important clinical and economic domains. In this commentary, the authors review the evidence supporting the existence of EE gaps in quality of life, time toxicity, cost and toxicities, and urge for further research into this important topic.

Effectiveness of Immune Checkpoint Inhibitors in Various Tumor Types Treated by Low, Per-Weight, and Conventional Doses at a Tertiary Care Center in Mumbai. JCO Glob Oncol 2024; 10:e2300312. [PMID: 38181308 DOI: 10.1200/go.23.00312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 10/17/2023] [Accepted: 10/31/2023] [Indexed: 01/07/2024] Open
Abstract
PURPOSE The cost of immune checkpoint inhibitors (ICIs) limits their accessibility to a small number of patients with cancer in low- and middle-income countries. Early-phase clinical trials have shown target inhibition and high activity at doses lower than those registered and evaluated in clinical trials. Here, we report everyday experience of using ICIs in 100 Indian patients, many of whom received lower doses of ICIs. METHODS Consecutive patients who received at least one dose of an ICI irrespective of tumor type at a tertiary care hospital in Mumbai, India, that was able to access ICIs for its patients were enrolled. The objectives were to study the doses used over a 3-year time period, and the effectiveness of therapy, assessed primarily by the overall response rate (ORR), overall survival (OS), and progression-free survival were secondary end points. RESULTS Twenty-five patients were treated with conventional doses of ICIs, 29 patients received lower doses per body weight, and 46 patients received low-dose treatment. The median number of cycles received was 5 (range, 1-28). Seventy-eight patients received ICIs in a palliative setting. The median follow-up time was 10.2, 9.8, and 3.9 months for those receiving fixed approved dosing, per body weight dosing, and low-dose treatment, respectively. There was a trend with time to prescribe lower doses. Response evaluation was available for 92 patients. Twenty-one (five-adjuvant and 16-palliative) patients received ICIs only. The ORR did not differ statistically among different dosing groups, but comparisons are confounded by inclusion of different ICIs, different tumor sites, and concurrent treatments. The median OS was 6.8 (range, 4.6-9.0) months. CONCLUSION Adoption of per-body weight and lower dosing of ICIs appears to give acceptable outcomes. Lower dosing can improve access and timely delivery of ICIs in low- and middle-income countries.

Abstract
Idecabtagene vicleucel (ide-cel) was the first FDA-approved chimeric antigen receptor T-cell therapy for relapsed/refractory multiple myeloma (RRMM) patients. This was the first study to evaluate patient-reported outcomes (PROs) among RRMM patients receiving ide-cel in standard of care (SOC). We prospectively assessed health-related quality of life (HRQOL) and symptoms from pre-infusion (baseline) through day (D)90 post-infusion. Baseline PRO associations with patient characteristics, mean PRO changes, and time to stable change were evaluated with t-tests, linear mixed-effects models, and Kaplan-Meier analyses, respectively. Within-person change scores and minimally important difference thresholds determined clinical and meaningful significance. Participants (n = 42) were a median of 66 years old (range: 43-81). At baseline, extramedullary disease was associated with worse physical well-being (p = 0.008), global pain (p < 0.001), performance status (p = 0.002), and overall symptom burden (p < 0.001). Fatigue (p < 0.001) and functional well-being (p = 0.003) worsened by D7 before returning to baseline levels. Overall HRQOL (p = 0.008) and physical well-being (p < 0.001) improved by D60. Most participants reported PRO improvement (10-57%) or maintenance (23-69%) by D90. The median time it took to stabile deterioration in functional well-being was 14 days. The median time it took to stabile improvement in physical and emotional well-being was 60 days. Overall, RRMM patients reported improvements or maintenance of HRQOL and symptom burden after SOC ide-cel.

Abstract
OBJECTIVES The objective of this study was to assess the clinical outcomes following combined treatment with pembrolizumab and axitinib as first-line therapy for patients with advanced RCC. METHODS This study retrospectively included 47 consecutive Japanese patients who were diagnosed with advanced RCC and subsequently received pembrolizumab and axitinib between February 2020 and January 2022. Efficacy and safety of this combined therapy in these patients were comprehensively investigated. RESULTS The 47 included patients were classified into the following 3 groups by the IMDC system: favorable, 7 (14.9%); intermediate, 24 (51.1%) and poor, 16 (34.0%). Responses to this combined therapy in the 47 patients were as follows: CR, 8 (17.0%); PR, 20 (42.6%); SD, 16 (34.0%) and PD, 3 (6.4%); thus, the ORR was 59.6%. During the observation period, disease progression and death occurred in 19 (40.4%) and 9 (19.1%) patients, respectively, and the median PFS and OS were 18 months and not reached, respectively. Univariate analyses identified the following significant predictors for poor prognostic outcomes: lack of nephrectomy, liver metastasis, bone metastasis, elevated CRP and IMDC poor risk for PFS; and lack of nephrectomy, non-CCC and elevated CRP for OS. AEs and those corresponding to grade ≥ 3 occurred in all (100%) and 30 (63.8%) patients, respectively. CONCLUSIONS To our knowledge, this is the first study focusing on real-world outcomes following pembrolizumab and axitinib for treatment-naïve advanced Japanese RCC patients, which showed the efficacy and safety of this combined therapy being similar or even superior to those in clinical trial.

Estimated Direct Costs of Renal Cancer by Stage of Disease at Diagnosis and Phase of Its Management: A Whole-Disease Model. Clin Genitourin Cancer 2023:S1558-7673(23)00034-4. [PMID: 36906433 DOI: 10.1016/j.clgc.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 01/31/2023] [Accepted: 02/04/2023] [Indexed: 02/11/2023]
Abstract
BACKGROUND Renal cell carcinoma (RCC) is the seventh most common neoplasm in high-income countries. New clinical pathways have been developed to deal with this tumor, which includes costly drugs that pose an economic threat to the sustainability of healthcare services. This study provides an estimate of the direct costs of care for patients with RCC by stage of disease (early vs. advanced) at diagnosis, and disease management phase along the pathway recommended by local and international guidelines. MATERIALS AND METHODS Considering the clinical pathway for RCC adopted in the Veneto region (north-east Italy) and the latest guidelines, we developed a very detailed "whole-disease" model that covers the probabilities of all potentially necessary diagnostic and therapeutic actions involved in the management of RCC. Based on the cost of each procedure according to the Veneto Regional Authority's official reimbursement tariffs, we estimated the total and average per-patient costs by stage of disease (early or advanced) and phase of its management. RESULTS In the first year after diagnosis, the mean expected cost of a patient with RCC is €12,991 if it is localized or locally-advanced and reaches €40,586 if it is advanced. For early disease, the main cost is incurred by surgery, whereas medical therapy (first and second line) and supportive care become increasingly important for metastatic disease. CONCLUSION It is crucially important to examine the direct costs of care for RCC, and to predict the burden on healthcare services of new oncological therapies and treatments, as the findings could be useful for policy-makers planning the allocation of resources.

Exposure-Response Analysis of Osimertinib in EGFR Mutation Positive Non-Small Cell Lung Cancer Patients in a Real-Life Setting. Pharm Res 2022; 39:2507-2514. [PMID: 35978149 DOI: 10.1007/s11095-022-03355-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 08/02/2022] [Indexed: 10/15/2022]
Abstract
BACKGROUND Osimertinib, an irreversible inhibitor of the epidermal growth factor receptor (EGFR) is an important drug in the treatment of EGFR-mutation positive non-small cell lung cancer (NSCLC). Clinical trials with osimertinib could not demonstrate an exposure-efficacy relationship, while a relationship between exposure and toxicity has been found. In this study, we report the exposure-response relationships of osimertinib in a real-life setting. METHODS A retrospective observational cohort study was performed, including patients receiving 40 - 80 mg osimertinib as ≥ 2 line therapy and from whom pharmacokinetic samples were collected during routine care. Trough plasma concentrations (Cmin,pred) were estimated and used as a measure of osimertinib exposure. A previously defined exploratory pharmacokinetic threshold of 166 µg/L was taken to explore the exposure-efficacy relationship. RESULTS A total of 145 patients and 513 osimertinib plasma concentration samples were included. Median progression free survival (PFS) was 13.3 (95% confidence interval (CI):10.3 - 19.1) months and 9.3 (95% CI: 7.2 - 11.1) months for patients with Cmin,pred < 166 µg/L and Cmin,pred ≥ 166 µg/L, respectively (p = 0.03). In the multivariate analysis, a Cmin,pred < 166 µg/L resulted in a non-statistically significant hazard ratio of 1.10 (95% CI: 0.60 - 2.01; p = 77). Presence of a EGFR driver-mutation other than the exon 19 del or L858R mutations, led to a shorter PFS with a hazard ratio of 2.89 (95% CI: 1.18 - 7.08; p = 0.02). No relationship between exposure and toxicity was observed (p = 0.91). CONCLUSION In our real-life cohort, no exposure-response relationship was observed for osimertinib in the current dosing scheme. The feasibility of a standard lower fixed dosing of osimertinib in clinical practice should be studied prospectively.

Abstract
PURPOSE Immune-based (IO)-combinations are the backbone in the systemic therapy of metastatic renal cell carcinoma (mRCC). Despite phase III clinical trial data, real world data are of special importance to reflect clinical practice. METHODS This retrospective study included 201 mRCC patients receiving first-line systemic therapy from January 2006. Clinicopathological and treatment-related data were recorded. Progression-free (PFS) and overall survival (OS) were analyzed using descriptive statistics and Kaplan-Meier analysis. RESULTS Over the years, IO-based therapies have increased significantly. The collective comprises 76 patients with first-line IO-based therapy (IO-IO:55, TKI-IO:21) and 125 patients with TKI-monotherapy. PFS was significantly improved with TKI-IO combinations if compared to both TKI-monotherapy (23.9 vs. 10.3 months, HR 0.48, p = 0.034) and IO-IO combination (23.9 vs. 6.1 months, HR 0.37, p = 0.012). OS for TKI-IO treated patients was longer compared to TKI-monotherapy (HR 0.37, p = 0.050) at median follow-up of 24.1 versus 29.9 months. In a subanalysis of nivolumab treated patients, starting from second-line (n = 40), PFS was 5.5 months. The addition of nivolumab either in second-or later lines improved OS compared to repeated TKI- or mTOR-therapies alone (6.13 vs. 2.61 years, HR 0.46, p = 0.003). CONCLUSION Both first-line IO-based combinations and nivolumab after first-line TKI-monotherapy prolong OS in a real-world setting.

Abstract
BackgroundCombination axitinib plus pembrolizumab is a standard of care in the first-line treatment of patients with advanced clear cell renal cell carcinoma (RCC). This analysis describes the clinical characteristics, treatment management and outcomes of patients receiving first-line (1L) axitinib plus pembrolizumab in a real-world US setting.MethodsElectronic health record (EHR)-derived data from the Flatiron Health Database, which includes ~280 cancer clinics across 800 sites in the US, were used. Patients had confirmed Stage IV or metastatic RCC and initiated 1L axitinib plus pembrolizumab on or after 1/1/2018 to 3/31/2021. Outcomes were best overall response rate; real-world progression-free survival (rwPFS) and overall survival (OS) at landmark time periods (3, 6, 9, and 12 months). Therapy management (TM) included dose hold, dose change and discontinuation. Data are reported as medians (IQR) unless otherwise noted.Results355 patients received 1L axitinib plus pembrolizumab, with median follow-up of 9.7 (0.1–24.3) months. IMDC Risk Score was favorable, intermediate, and poor in 27 (7.6%), 126 (35.5%), and 76 (21.4%) patients, respectively (23.4% intermediate/poor, 12.1% unknown). 270 patients (76.1%) received only 1L axitinib plus pembrolizumab and 85 patients (24.3%) received ≥1 subsequent line of treatment; cabozantinib was the most frequent subsequent line of treatment (47.9%). rwPFS at 3 months and 1 year was 77.2% and 39.3%, respectively. OS ranged from 90.8% at 3 months to 73.5% at 1 year. Best overall response rate was 47.9%. Toxicity was the most common reason for first TM events of dose hold, change and discontinuation at, 58.6%, 58.5%, and 45.8%, respectively. Over 80% of patients with TM were able to continue with 1L axitinib plus pembrolizumab.ConclusionsIn a real-world setting, axitinib plus pembrolizumab was effective as a 1L treatment for patients with advanced RCC. Dose holds, changes and discontinuation were driven by treatment-related toxicity. Dose holds may represent an effective TM strategy to toxicity.

Abstract
IMPORTANCE Adjuvant drugs are used to reduce the risk of tumor recurrence in patients with cancer who are successfully treated with first-line therapy. The same drugs used in the metastatic or first-line setting are often used in the adjuvant setting, and although the resulting adverse effects may be similar between the 2 settings, tolerability may be different. OBJECTIVE To compare the discontinuation rates of drugs in the adjuvant setting and in the metastatic setting in clinical trials of cancer drugs. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study examined clinical trials of cancer drugs with results published in major medical and oncology journals between July 2018 through June 2021. Because adjuvant drugs can be used in a metastatic setting, included trials were conducted in an adjuvant setting. Data were analyzed December 2021. EXPOSURES Drugs used in the adjuvant setting, which were also used in the metastatic setting for the same tumor indication. MAIN OUTCOMES AND MEASURES Discontinuation rates in the adjuvant and metastatic settings, which were calculated by dividing the total number of study participants who withdrew or discontinued because of adverse events by the number of participants allocated to the drug arm. RESULTS A total of 29 trials with a drug being used in the adjuvant and metastatic setting were found. In the adjuvant setting, the median (IQR) age for study participants was 58.0 (52.0-63.5) years, and the median (IQR) percentage of male participants was 55.5% (0.9%-64.8%). In the metastatic setting, the median (IQR) age for study participants was 61 years, and the median (IQR) percentage of male participants was 55.2% (2.0%-66.0%). Overall, a median (IQR) 21.4% (17.7%-29.4%) of participants discontinued because of adverse events or patient withdrawal in the adjuvant setting compared with a median (IQR) 15.9% (9.7%-21.3%) in the metastatic setting (P = .01). Checkpoint inhibitors (median [IQR] rate of discontinuation, 21.4% [18.6%-31.3%] vs 15.2% [9.9%-19.5%]; P = .01) and targeted drugs (median [IQR] rate of discontinuation, 27.7% vs 14.0%; P < .001) demonstrated a higher rate of discontinuation in the adjuvant setting while cytotoxic drugs (median [IQR] rate of discontinuation, 16.6% [12.2%-23.3%] vs 25.5% [19.8%-28.8%]; P = .07) showed no difference between the 2 settings. The largest differences between adjuvant and metastatic discontinuation rates were for sorafenib (renal cell carcinoma, 43.8% vs 5.5%; difference, 38.2%), imatinib (gastrointestinal stromal tumor, 37.4% vs 6.1%; difference, 31.2%), and erlotinib (non-small cell lung cancer, 37.5% vs 8.4%; difference, 29.0%). CONCLUSIONS AND RELEVANCE In this cross-sectional study of clinical trials that involved novel cancer drugs, drugs used in the adjuvant setting were associated with significantly higher discontinuation rates than in the metastatic setting. This finding suggests that the proposed benefits of adjuvant therapy need to be taken in context of patient's drug tolerance.

Abstract
Aim In the registration trial, cabozantinib exposure ≥ 750 ng/mL correlated to improved tumor size reduction, response rate and progression free survival (PFS) in patients with metastatic renal cell cancer (mRCC). Because patients in routine care often differ from patients in clinical trials, we explored the cabozantinib exposure–response relationship in patients with mRCC treated in routine care. Methods Cabozantinib trough concentrations (Cmin) were collected and average exposure was calculated per individual. Exposure–response analyses were performed using the earlier identified target of Cmin > 750 ng/mL and median Cmin. In addition, the effect of dose reductions on response was explored. PFS was used as measure of response. Results In total, 59 patients were included:10% were classified as favourable, 61% as intermediate and 29% as poor IMDC risk group, respectively. Median number of prior treatment lines was 2 (0–5). Starting dose was 60 mg in 46%, 40 mg in 42% and 20 mg in 12% of patients. Dose reductions were needed in 58% of patients. Median Cmin was 572 ng/mL (IQR: 496–701). Only 17% of patients had an average Cmin ≥ 750 ng/mL. Median PFS was 52 weeks (95% CI: 40–64). No improved PFS was observed for patients with Cmin ≥ 750 ng/mL or ≥ 572 ng/ml. A longer PFS was observed for patients with a dose reduction vs. those without (65 vs. 31 weeks, p = .001). After incorporating known covariates (IMDC risk group and prior treatment lines (< 2 vs. ≥ 2)) in the multivariable analysis, the need for dose reduction remained significantly associated with improved PFS (HR 0.32, 95% CI:0.14–0.70, p = .004). Conclusion In these explorative analyses, no clear relationship between increased cabozantinib exposure and improved PFS was observed. Average cabozantinib exposure was below the previously proposed target in 83% of patients. Future studies should focus on validating the cabozantinib exposure required for long term efficacy.

Exposure-toxicity relationship of cabozantinib in patients with renal cell cancer and salivary gland cancer. Int J Cancer 2021; 150:308-316. [PMID: 34494665 PMCID: PMC9291492 DOI: 10.1002/ijc.33797] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 07/23/2021] [Accepted: 08/17/2021] [Indexed: 01/18/2023]
Abstract
Cabozantinib is registered in fixed 60 mg dose. However, 46% to 62% of patients in the registration studies needed a dose reduction due to toxicity. Improved clinical efficacy has been observed in renal cell carcinoma patients (RCC) with a cabozantinib exposure greater than 750 μg/L. In our study we explored the cabozantinib exposure in patients with different tumour types. We included RCC patients from routine care and salivary gland carcinoma (SGC) patients from a phase II study with ≥1 measured Cmin at steady‐state. The geometric mean (GM) Cmin at the starting dose, at 40 mg and at best tolerated dose (BTD) were compared between both tumour types. Forty‐seven patients were included. All SGC patients (n = 22) started with 60 mg, while 52% of RCC patients started with 40 mg. GM Cmin at the start dose was 1456 μg/L (95% CI: 1185‐1789) vs 682 μg/L (95% CI: 572‐812) (P < .001) for SGC and RCC patients, respectively. When dose‐normalised to 40 mg, SGC patients had a significantly higher cabozantinib exposure compared to RCC patients (Cmin 971 μg/L [95% CI: 790‐1193] vs 669 μg/L [95% CI: 568‐788]) (P = .005). Dose reductions due to toxicity were needed in 91% and 60% of SGC and RCC patients, respectively. Median BTD was between 20 to 30 mg for SGC and 40 mg for RCC patients. GM Cmin at BTD were comparable between the SGC and the RCC group, 694 μg/L (95% CI: 584‐824) vs 583 μg/L (95% CI: 496‐671) (P = .1). The observed cabozantinib exposure at BTD of approximately 600 μg/L is below the previously proposed target. Surprisingly, a comparable exposure at BTD was reached at different dosages of cabozantinib for SGC patients compared to RCC patients Further research is warranted to identify the optimal exposure and starting dose to balance efficacy and toxicity.
What's new?
Cabozantinib, a potent tyrosine kinase inhibitor that targets multiple signaling pathways, is approved for use against advanced renal cell carcinoma (RCC). Variations in cabozantinib clearance, however, warrant further investigation. Here, the authors evaluated cabozantinib exposure in RCC patients and in patients with salivary gland cancer (SGC). SGC patients were found to have significantly higher cabozantinib exposure compared to RCC patients following a 40 mg dose. However, the best‐tolerated cabozantinib exposure was equivalent (~600 μg/L) for both tumor types and was substantially below the previously proposed target. The findings offer insight on exposure, dose, and the balance between efficacy and toxicity for cabozantinib.

Abstract
BACKGROUND Acute ankle fractures can occur during sports activities, and unstable ankle fractures are commonly treated operatively. However, controversy exists about the optimal time to allow weightbearing. HYPOTHESIS Early weightbearing after the stable fixation of an ankle fracture is not inferior to nonweightbearing in terms of ankle function assessed at 12 months after injury. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A total of 258 patients were assessed for eligibility. Of these patients, 194 were randomly allocated to either the early weightbearing group (95 patients who were allowed weightbearing at 2 weeks postoperatively) or the nonweightbearing group (99 patients who were not allowed weightbearing until 6 weeks postoperatively). The primary outcome measure was the mean difference in the Olerud-Molander ankle score (OMAS) between the groups, assessed at the 12-month follow-up examination. The secondary outcome measures were the time to return to preinjury activities and patients' subjective satisfaction. Complications such as hardware loosening or failure, fracture displacement, and nonunion were evaluated. RESULTS The mean difference in the OMAS for the early weightbearing group compared with the nonweightbearing group was 1.6 (95% CI, -1.9 to 5.0) in the intention-to-treat analysis. The lower limit of the 95% CI (-1.9) exceeded the noninferiority margin of -8, indicating that early weightbearing was not inferior to nonweightbearing. The difference in the proportion of patients who were satisfied or very satisfied with their treatment was not statistically significant (84.3% vs 76.2%; P = .19); however, the time taken to return to preinjury activities was shorter with early weightbearing than with nonweightbearing (9.1 ± 3.0 vs 11.0 ± 3.0 weeks; P < .001). No cases of nonunion were observed in either group. CONCLUSION Early weightbearing after the operative treatment of an unstable ankle fracture was not inferior to nonweightbearing in terms of OMAS assessed at 12 months after injury. The patients' subjective satisfaction was similar between the groups, although the time taken to return to preinjury activities was shorter in the early weightbearing group.

Abstract
INTRODUCTION The Metastatic Renal Cell Carcinoma (MaRCC) Registry provides prospective data on real-world treatment patterns and outcomes in patients with metastatic renal cell carcinoma (mRCC). METHODS AND MATERIALS Patients with mRCC and no prior systemic therapy were enrolled at academic and community sites. End of study data collection was in March 2019. Outcomes included overall survival (OS). A survey of treating physicians assessed reasons for treatment initiations and discontinuations. RESULTS Overall, 376 patients with mRCC initiated first-line therapy; 171 (45.5%) received pazopanib, 75 (19.9%) sunitinib, and 74 (19.7%) participated in a clinical trial. Median (95% confidence interval) OS was longest in the clinical trial group (50.3 [35.8-not reached] months) versus pazopanib (39.0 [29.7-50.9] months) and sunitinib 26.2 [19.9-61.5] months). Non-clear cell RCC (21.5% of patients) was associated with worse median OS than clear cell RCC (18.0 vs. 47.3 months). Differences in baseline characteristics, treatment starting dose, and relative dose exposure among treatment groups suggest selection bias. Survey results revealed a de-emphasis on quality of life, toxicity, and patient preference compared with efficacy in treatment selection. CONCLUSION The MaRCC Registry gives insights into real-world first-line treatment selection, outcomes, and physician rationale regarding initial treatment selection prior to the immunotherapy era. Differences in outcomes between clinical trial and off-study patients reflect the difficulty in translating trial results to real-world patients, and emphasize the need to broaden clinical trial eligibility. Physician emphasis on efficacy over quality of life and toxicity suggests more data and education are needed regarding these endpoints.

Abstract
BACKGROUND Systemic therapy (ST) can be deferred in patients who have metastatic renal cell carcinoma (mRCC) and slow-growing metastases. Currently, this subset of patients managed with active surveillance (AS) is not well described in the literature. METHODS This was a prospective observational study of patients with mRCC across 46 US community and academic centers. The objective was to describe baseline characteristics and demographics of patients with mRCC initially managed by AS, reasons for AS, and patient outcomes. Descriptive statistics were used to characterize demographics, baseline characteristics, and patient-related outcomes. Wilcoxon 2-sample rank-sum tests and χ2 tests were used to assess differences between ST and AS cohorts in continuous and categorical variables, respectively. Kaplan-Meier survival curves were used to assess survival. RESULTS Of 504 patients, mRCC was initially managed by AS (n = 143) or ST (n = 305); 56 patients were excluded from the analysis. Disease was present in 69% of patients who received AS, whereas the remaining 31% had no evidence of disease. At data cutoff, 72 of 143 patients (50%) in the AS cohort had not received ST. The median overall survival was not reached (95% CI, 122 months to not estimable) in patients who received AS versus 30 months (95% CI, 25-44 months) in those who received ST. Quality of life at baseline was significantly better in patients who were managed with AS versus ST. CONCLUSIONS AS occurs frequently (32%) in real-world clinical practice and appears to be a safe and appropriate alternative to immediate ST in selected patients.

The effectiveness of systemic therapies after surgery for metastatic renal cell carcinoma to the spine: a propensity analysis controlling for sarcopenia, frailty, and nutrition. J Neurosurg Spine 2021:1-10. [PMID: 34171829 DOI: 10.3171/2020.12.spine201896] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 12/09/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The effectiveness of starting systemic therapies after surgery for spinal metastases from renal cell carcinoma (RCC) has not been evaluated in randomized controlled trials. Agents that target tyrosine kinases, mammalian target of rapamycin signaling, and immune checkpoints are now commonly used. Variables like sarcopenia, nutritional status, and frailty may impact recovery from spine surgery and are considered when evaluating a patient's candidacy for such treatments. A better understanding of the significance of these variables may help improve patient selection for available treatment options after surgery. The authors used comparative effectiveness methods to study the treatment effect of postoperative systemic therapies (PSTs) on survival. METHODS Univariable and multivariable Cox regression analyses were performed to determine factors associated with overall survival (OS) in a retrospective cohort of adult patients who underwent spine surgery for metastatic RCC between 2010 and 2019. Propensity score-matched (PSM) analysis and inverse probability weighting (IPW) were performed to determine the treatment effect of PST on OS. To address confounding and minimize bias in estimations, PSM and IPW were adjusted for covariates, including age, sex, frailty, sarcopenia, nutrition, visceral metastases, International Metastatic RCC Database Consortium (IMDC) risk score, and performance status. RESULTS In total, 88 patients (73.9% male; median age 62 years, range 29-84 years) were identified; 49 patients (55.7%) had an intermediate IMDC risk, and 29 (33.0%) had a poor IMDC risk. The median follow-up was 17 months (range 1-104 months) during which 57 patients (64.7%) died. Poor IMDC risk (HR 3.2 [95% CI 1.08-9.3]), baseline performance status (Eastern Cooperative Oncology Group score 3 or 4; HR 2.7 [95% CI 1.5-4.7]), and nutrition (prognostic nutritional index [PNI] first tertile, PNI < 40.74; HR 2.69 [95% CI 1.42-5.1]) were associated with worse OS. Sarcopenia and frailty were not significantly associated with poor survival. PST was associated with prolonged OS, demonstrated by similar effects from multivariable Cox analysis (HR 0.55 [95% CI 0.30-1.00]), PSM (HR 0.53 [95% CI 0.29-0.93]), IPW (HR 0.47 [95% CI 0.24-0.94]), and comparable confidence intervals. The median survival for those receiving PST was 28 (95% CI 19-43) months versus 12 (95% CI 4-37) months for those who only had surgery (log-rank p = 0.027). CONCLUSIONS This comparative analysis demonstrated that PST is associated with improved survival in specific cohorts with metastatic spinal RCC after adjusting for frailty, sarcopenia, and malnutrition. The marked differences in survival should be taken into consideration when planning for surgery.

Abstract
OBJECTIVE Real-world data (RWD), defined as routinely collected healthcare data, can be a potential catalyst for addressing challenges faced in clinical trials. We performed a scoping review of database-specific RWD applications within clinical trial contexts, synthesizing prominent uses and themes. MATERIALS AND METHODS Querying 3 biomedical literature databases, research articles using electronic health records, administrative claims databases, or clinical registries either within a clinical trial or in tandem with methodology related to clinical trials were included. Articles were required to use at least 1 US RWD source. All abstract screening, full-text screening, and data extraction was performed by 1 reviewer. Two reviewers independently verified all decisions. RESULTS Of 2020 screened articles, 89 qualified: 59 articles used electronic health records, 29 used administrative claims, and 26 used registries. Our synthesis was driven by the general life cycle of a clinical trial, culminating into 3 major themes: trial process tasks (51 articles); dissemination strategies (6); and generalizability assessments (34). Despite a diverse set of diseases studied, <10% of trials using RWD for trial process tasks evaluated medications or procedures (5/51). All articles highlighted data-related challenges, such as missing values. DISCUSSION Database-specific RWD have been occasionally leveraged for various clinical trial tasks. We observed underuse of RWD within conducted medication or procedure trials, though it is subject to the confounder of implicit report of RWD use. CONCLUSION Enhanced incorporation of RWD should be further explored for medication or procedure trials, including better understanding of how to handle related data quality issues to facilitate RWD use.

Abstract
OBJECTIVE To present a generalizability assessment method that compares baseline clinical characteristics of trial participants (TP) to potentially eligible (PE) patients as presented in their electronic health record (EHR) data while controlling for clinical setting and recruitment period. METHODS For each clinical trial, a clinical event was defined to identify patients of interest using available EHR data from one clinical setting during the trial's recruitment timeframe. The trial's eligibility criteria were then applied and patients were separated into two mutually exclusive groups: (1) TP, which were patients that participated in the trial per trial enrollment data; (2) PE, the remaining patients. The primary outcome was standardized differences in clinical characteristics between TP and PE per trial. A standardized difference was considered prominent if its absolute value was greater than or equal to 0.1. The secondary outcome was the difference in mean propensity scores (PS) between TP and PE per trial, in which the PS represented prediction for a patient to be in the trial. Three diverse trials were selected for illustration: one focused on hepatitis C virus (HCV) patients receiving a liver transplantation; one focused on leukemia patients and lymphoma patients; and one focused on appendicitis patients. RESULTS For the HCV trial, 43 TP and 83 PE were found, with 61 characteristics evaluated. Prominent differences were found among 69% of characteristics, with a mean PS difference of 0.13. For the leukemia/lymphoma trial, 23 TP and 23 PE were found, with 39 characteristics evaluated. Prominent differences were found among 82% of characteristics, with a mean PS difference of 0.76. For the appendicitis trial, 123 TP and 242 PE were found, with 52 characteristics evaluated. Prominent differences were found among 52% of characteristics, with a mean PS difference of 0.15. CONCLUSIONS Differences in clinical characteristics were observed between TP and PE among all three trials. In two of the three trials, not all of the differences necessarily compromised trial generalizability and subsets of PE could be considered similar to their corresponding TP. In the remaining trial, lack of generalizability appeared present, but may be a result of other factors such as small sample size or site recruitment strategy. These inconsistent findings suggest eligibility criteria alone are sometimes insufficient in defining a target group to generalize to. With caveats in limited scalability, EHR data quality, and lack of patient perspective on trial participation, this generalizability assessment method that incorporates control for temporality and clinical setting promise to better pinpoint clinical patterns and trial considerations.

Abstract
AIMS/HYPOTHESIS More than 25% of older adults (age ≥75 years) have diabetes and may be at risk of adverse events related to treatment. The aim of this study was to assess the prevalence of intensive glycaemic control in this group, potential overtreatment among older adults and the impact of overtreatment on the risk of serious events. METHODS We conducted a retrospective, population-based cohort study of community-dwelling older adults in Ontario using administrative data. Participants were ≥75 years of age with diagnosed diabetes treated with at least one anti-hyperglycaemic agent between 2014 and 2015. Individuals were categorised as having intensive or conservative glycaemic control (HbA1c <53 mmol/mol [<7%] or 54-69 mmol/mol [7.1-8.5%], respectively), and as undergoing treatment with high-risk (i.e. insulin, sulfonylureas) or low-risk (other) agents. We measured the composite risk of emergency department visits, hospitalisations, or death within 30 days of reaching intensive glycaemic control with high-risk agents. RESULTS Among 108,620 older adults with diagnosed diabetes in Ontario, the mean (± SD) age was 80.6 (±4.5) years, 49.7% were female, and mean (± SD) diabetes duration was 13.7 (±6.3) years. Overall, 61% of individuals were treated to intensive glycaemic control and 21.6% were treated to intensive control using high-risk agents. Using inverse probability treatment weighting with propensity scores, intensive control with high-risk agents was associated with nearly 50% increased risk of the composite outcome compared with conservative glycaemic control with low-risk agents (RR 1.49, 95% CI 1.08, 2.05). CONCLUSIONS/INTERPRETATION Our findings underscore the need to re-evaluate glycaemic targets in older adults and to reconsider the use of anti-hyperglycaemic medications that may lead to hypoglycaemia, especially in setting of intensive glycaemic control.

Abstract
INTRODUCTION Pivotal Randomized Controlled Trials (RCTs) constitute scientific evidence in support of therapeutic choices when a drug is authorized in the market. In RCTs, patients are selected in a rigorous manner, in order to avoid bias that may influence efficacy assessments. Therefore, patients who take the drug in Real Life Studies (RLSs) are not the same as those participating in RCTs, which, in turn, leads to low data transferability from RCTs to RLS. The objective of this study was to evaluate the differences between RCTs and RLS, in terms of patient baseline characteristics. MATERIALS AND METHODS Our study includes all oral target therapies for RCC (Renal Cell Carcinoma) marketed in Europe before March 31, 2019. For each treatment, we considered both RCTs and RLSs, the former gathered from Summary of Product Characteristics published on the European Medicine Agency (EMA) website, and the latter yielded by our search in relevant literature. For each drug considered, we then compared the baseline characteristics of patients included in the RCT samples with those of the samples included in the RLSs using the Chi-squared and Mann-Whitney tests. RESULTS We considered six medicines, for a total of 9 pivotal RCTs and 31 RLSs. RCTs reported the same type of patient baseline characteristics, whereas RLSs are more varied in reporting. Some patient baseline characteristics (metastases, previous treatments, etc.) were significantly different between RCTs and RLs. Other characteristics, such as ECOG Performance Status, brain metastases, and comorbidities, liver and kidney failure, are comprised in exclusion criteria of RCTs, though are included in RLS.Discussion and Conclusion: While evaluating equal treatments for the same indications, RCTs and RLSs do not always assess patients with the same characteristics. It would be necessary to produce evidence from RLSs so as to have an idea of treatment effectiveness in patients groups that are not eligible or underrepresented in RCTs.

Abstract
OBJECTIVE We compared 5-year outcomes of transcatheter pulmonary valve (TPV) replacement with the Melody TPV in the post-approval study (PAS) and the investigational device exemption (IDE) trial. BACKGROUND As a condition of approval of the Melody TPV after the IDE trial, the Food and Drug Administration required that a PAS be conducted to evaluate outcomes of TPV replacement in a "real-world" environment. The 5-year outcomes of the PAS have not been published, and the IDE and PAS trials have not been compared. METHODS The cohorts comprised all patients catheterized and implanted at 5 IDE sites and 10 PAS sites. Differences in trial protocols were detailed. Time-related outcomes and valve-related adverse events were compared between the two trials with Kaplan-Meier curves and log-rank testing. RESULTS 167 patients (median age, 19 years) were catheterized and 150 underwent TPV replacement in the IDE trial; 121 were catheterized (median age, 17 years) and 100 implanted in the PAS. Freedom from hemodynamic dysfunction (p = .61) or any reintervention (p = .74) over time did not differ between trials. Freedom from stent fracture (p = .003) and transcatheter reintervention (p = .010) were longer in PAS, whereas freedom from explant (p = .020) and TPV endocarditis (p = .007) were shorter. Clinically important adverse events (AEs) were reported in 14% of PAS and 7.2% of IDE patients (p = .056); the incidence of any particular event was low in both. CONCLUSIONS Hemodynamic and time-related outcomes in the PAS and IDE trials were generally similar, confirming the effectiveness of the Melody TPV with real-world providers. There were few significant complications and limited power to identify important differences in AEs. The lack of major differences in outcomes between the two studies questions the usefulness of mandated costly post-approval studies as part of the regulatory process for Class III medical devices.

Abstract
Aim: To analyze responses to first-line metastatic renal cell carcinoma (mRCC) treatment stratified by risk criteria. Patients & methods: Clinical trials and observational studies of patients aged ≥18 years, published January 2005-May 2019, were identified via Ovid from MEDLINE, EMBASE, the Cochrane Central Trials Register and the Cochrane Database of Systematic Reviews. Data extracted included progression-free survival (PFS), overall survival (OS) and objective response rate (ORR). Results: 47/1269 articles met eligibility criteria. Most studies stratified patients by International Metastatic RCC Database Consortium (n = 19) or Memorial Sloan Kettering Cancer Center (n = 21). PFS, OS and ORR varied according to risk group. Conclusion: Pembrolizumab + axitinib, ipilimumab + nivolumab and avelumab + axitinib were most effective across all risk groups. Favorable-risk patients benefit from sunitinib treatment.

Abstract
BACKGROUND/AIM Previous research has suggested that patients with metastatic renal cell cancer (mRCC) and bone metastases have a poorer prognosis compared to their counterparts with no skeletal involvement. Therefore, we analyzed the management and outcomes of such patients in our center. PATIENTS AND METHODS We performed a retrospective study of 35 consecutive patients who received systemic treatment, largely targeted therapy, for mRCC with bone metastases. RESULTS The median overall survival was 25 months from the time of diagnosis of mRCC. The 5-year survival rate was 16%. Survival from diagnosis of mRCC was significantly worse in patients with bone metastases present at the start of first-line systemic therapy (median 13 months) compared to delayed metastases diagnosed later during the course of disease (46 months, p=0.01). Few patients (29%) were able to receive more than two lines of systemic therapy. Bone-only metastases were uncommon (11%). CONCLUSION Most patients with mRCC and bone metastases have limited overall survival.

Abstract
The experience of patients with mantle cell lymphoma (MCL) in community oncology practices, including reasons for treatment discontinuation, is sparse. This retrospective study sought to elucidate treatment patterns and outcomes of patients with MCL treated with ibrutinib in the community setting. Patients were identified from the US Oncology Network electronic medical records database, iKnowMedTM , between 1 November 2013 and 31 October 2016. Descriptive analysis was performed to describe the demographic and clinical characteristics of the population. Kaplan-Meier estimates were performed to determine clinical outcomes. A Cox proportional hazards model was used to identify predictors of survival. Of the 1914 patients identified with MCL, 159 were treated with ibrutinib. The median age was 71 years and the majority were male (76%) and Caucasian (89%). The overall discontinuation rate was 83·6%; the most common reasons were progression (35%) and toxicities (25·6%). The median overall survival and progression-free survival was 25·82 months (95% confidence interval [CI] 19·94, NR) and 19·55 months (95% CI 16·52, 24·28) respectively. In multivariate modelling, patient age was predictive of survival (hazard ratio 1·041, P = 0·0186). Ibrutinib was temporarily reduced in 16·4% (n = 26) and held in 30·2% (n = 48), primarily due to toxicity 66·7% (n = 32). Survival data showed similarities between community oncology practices and clinical trials.

Abstract
Real-world evidence (RWE) provides a potential rich source of additional information to the body of data available from randomized clinical trials (RCTs), but there is a need to understand the strengths and limitations of RWE before it can be applied to clinical practice. To gain insight into current thinking in clinical decision making and utility of different data sources, a representative sampling of US cardiologists selected from the current, active Fellows of the American College of Cardiology (ACC) were surveyed to evaluate their perceptions of findings from RCTs and RWE studies and their application in clinical practice. The survey was conducted online via the ACC web portal between 12 July and 11 August 2017. Of the 548 active ACC Fellows invited as panel members, 173 completed the survey (32% response), most of whom were board certified in general cardiology (n = 119, 69%) or interventional cardiology (n = 40, 23%). The survey results indicated a wide range of familiarity with and utilization of RWE amongst cardiologists. Most cardiologists were familiar with RWE and considered RWE in clinical practice at least some of the time. However, a significant minority of survey respondents had rarely or never applied RWE learnings in their clinical practice, and many did not feel confident in the results of RWE other than registry data. These survey findings suggest that additional education on how to assess and interpret RWE could help physicians to integrate data and learnings from RCTs and RWE to best guide clinical decision making.

Exposure-Response Analyses of Anaplastic Lymphoma Kinase Inhibitors Crizotinib and Alectinib in Non-Small Cell Lung Cancer Patients. Clin Pharmacol Ther 2020; 109:394-402. [PMID: 32686074 PMCID: PMC7891593 DOI: 10.1002/cpt.1989] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 06/30/2020] [Indexed: 12/19/2022]
Abstract
Crizotinib and alectinib are anaplastic lymphoma kinase (ALK)-inhibitors indicated for the treatment of ALK-positive metastatic non-small cell lung cancer (NSCLC). At the currently used fixed doses, interindividual variability in exposure is high. The aim of this study was to investigate whether minimum plasma concentrations (Cmin ) of crizotinib and alectinib are related to efficacy and toxicity. An observational study was performed, in which ALK-positive NSCLC patients who were treated with crizotinib and alectinib and from whom pharmacokinetic samples were collected in routine care, were included in the study. Exposure-response analyses were explored using previously proposed Cmin thresholds of 235 ng/mL for crizotinib and 435 ng/mL for alectinib. Forty-eight crizotinib and 52 alectinib patients were included. For crizotinib, median progression-free survival (mPFS) was 5.7 vs. 17.4 months for patients with Cmin < 235 ng/mL (48%) and ≥ 235 ng/mL, respectively (P = 0.08). In multivariable analysis, Cmin < 235 ng/mL resulted in a hazard ratio (HR) of 1.79 (95% confidence interval (CI), 0.90-3.59, P = 0.100). In a pooled analysis of all crizotinib patients (not only ALK-positive, n = 79), the HR was 2.15 (95% CI, 1.21-3.84, P = 0.009). For alectinib, mPFS was 12.6 months vs. not estimable (95% CI, 19.8-not estimable) for patients with Cmin < 435 ng/mL (37%) and ≥ 435 ng/mL, respectively (P = 0.04). Multivariable analysis resulted in an HR of 4.29 (95% CI, 1.33-13.90, P = 0.015). In conclusion, PFS of crizotinib and alectinib treated NSCLC patients is prolonged in patients with Cmin ≥ 235 ng/mL and 435 ng/mL, respectively. Therefore, therapeutic drug monitoring should be part of routine clinical management for these agents.

Representation of therapy-related myelodysplastic syndrome in clinical trials over the past 20 years. Blood Adv 2020; 3:2738-2747.

Abstract
Therapy-related myelodysplastic syndrome (t-MDS), defined as MDS occurring after previous exposure to chemotherapy or radiotherapy, constitutes 10% to 20% of all MDS diagnoses. t-MDS patients tend to have higher-risk disease and worse outcomes than de novo MDS patients and are often excluded from therapeutic clinical trials. To explore this further, we extracted clinical trials across all status types registered on ClinicalTrials.gov from 1999 to 2018 studying untreated MDS patients. Using these specific search criteria, we analyzed 317 therapeutic MDS trials based on study status, therapeutic indication, eligibility criteria, and sponsor type to examine if these factors influenced t-MDS patient inclusion. Only 18 studies (5.7%) accrued 231 t-MDS patients in total, representing 3.2% of the total accrued MDS trial patient population. Fewer t-MDS patients were accrued in therapeutic trials sponsored by pharmaceutical sponsors vs nonpharmaceutical sponsors (2.8% vs 4.0%; P = .0073). This pattern of exclusion continues in actively enrolling trials; only 5 (10%) of 49 studies specifically mention the inclusion of t-MDS patients in their eligibility criteria. Our results indicate that therapeutic MDS trials seem to exclude t-MDS patients, rendering study results less applicable to this subset of MDS patients, who often have poor outcomes. Our study emphasizes the importance of the recent focus by National Cancer Institute cooperative groups and societies to broaden eligibility criteria for all patients.

Abstract
Background Immune checkpoint inhibitors (ICIs) are increasingly used in the treatment of cancers. We aimed to evaluate the incidence and prognostic impact of hepatic adverse events (AEs) in a territory‐wide cohort of patients who received ICIs. Methods Patients were identified from a territory‐wide database who received ICIs in 2014‐2018. Hepatic AEs were defined as any elevation of liver biochemistries including serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), or total bilirubin levels. Hepatic AEs were graded according to Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Results Total of 1480 patients were identified (mean age 60 years, male 65.5%) and the commonest malignancies being lung cancer (39.6%), liver cancer (16.5%), and gastrointestinal cancer (10.0%). Grade 1‐2 and grade 3‐4 hepatic AEs occurred in 41.3% and 14.9% of patients during ICI treatment, respectively. Patients with liver cancer had the highest rate of hepatic AEs (grade 1‐2:54.1%; grade 3‐4:32.8%). Among 711 patients with hepatic AEs, 383 (53.9%) had raised ALT/AST only, and 328 (46.1%) had concomitant raised ALT/AST and bilirubin levels. In the whole cohort, median overall survival of patients without any hepatic AEs, grade 1‐2 and grade 3‐4 hepatic AEs during ICI treatment was 9.0 months, 7.2 months, and 3.3 months (P < .001), respectively. Similar results on overall survival were obtained among different types of cancers. Conclusions Hepatic AEs occur in more than half of patients receiving ICIs for cancer treatment, with approximately 15% being grade 3‐4 AEs. Occurrence of hepatic AEs is associated with worse prognosis.

Abstract
Aim Sunitinib is an oral tyrosine kinase inhibitor approved for the treatment of renal cell carcinoma (RCC) and gastrointestinal stromal tumor (GIST). Because of the large interpatient pharmacokinetic variability and established exposure‐response and exposure‐toxicity relationships in clinical trial patients, therapeutic drug monitoring (TDM) seems promising for optimizing sunitinib exposure. We aimed to investigate the relationship between sunitinib exposure and treatment outcome in a real‐world patient cohort. Methods We performed a retrospective observational cohort study in 53 patients with metastatic RCC and 18 patients with metastatic GIST treated with sunitinib and receiving TDM‐guided dosing. Time on treatment – as a surrogate for progression‐free survival – in patients who achieved adequate sunitinib exposure was compared with patients who did not. Additionaly, the median sunitinib exposure was compared in patients with or without sunitinib‐induced toxicity leading to dose reduction. Results The median time on treatment in patients with RCC who achieved adequate sunitinib exposure (n = 39) was 32 weeks, compared to 15 weeks in patients who did not achieve adequate sunitinib exposure (n = 12) (P = 0.244). In 29 patients (41%) with toxicity leading to dose reduction, sunitinib sum plasma trough concentration (Ctrough) until dose reduction was significantly higher compared to patients without toxicity leading to dose reduction (median 60 ng/mL vs 44 ng/mL; P < 0.001) and reduced to comparable levels after dose reduction (44 ng/mL; P = 0.488). Conclusion In our real‐world patient cohort, patients with sunitinib‐induced toxicity requiring dose reduction had significantly higher sunitinib exposure compared to patients without toxicity. The threshold for toxicity, however, was lower compared to that previously described in clinical trials.

Abstract
Background Randomized controlled trials (RCTs) have stringent inclusion criteria and may not fully represent patients seen in everyday clinical practice. Real-world data (RWD) can provide supportive evidence for the effectiveness of medical interventions in more heterogeneous populations than RCTs. Sunitinib is a widely used first-line treatment for patients with metastatic renal cell carcinoma (mRCC). Objective This is the first comprehensive meta-analysis to evaluate the efficacy of sunitinib using the novel approach of combining RCTs and RWD. Methods RCTs and RWD studies published between 2000 and 2017 were identified from PubMed, Ovid, MEDLINE, and EMBASE. Eligible studies contained a cohort of ≥ 50 adult patients with mRCC receiving first-line sunitinib treatment. The meta-analysis combined RWD and RCT treatment groups, adjusting for data type (RCT or RWD). Recorded outcomes were median progression-free survival (mPFS), median overall survival (mOS), and objective response rate (ORR). Publication bias was assessed via review of funnel plots for each outcome measure. A random effects model to account for study heterogeneity was applied to each endpoint. Sensitivity analyses evaluated the robustness of the overall estimates. Results Of the 3611 studies identified through medical database searches, 22 (15 RWD studies, 7 RCTs) met eligibility criteria and were analyzed. mPFS (18 studies), mOS (19 studies), and ORR (15 studies) were reported for aggregate measures based on 4815, 5321, and 4183 patients, respectively. Reported mPFS (RWD, 7.5–11.0 months; RCTs, 5.6–15.1 months) and ORR data (RWD, 14.0–34.6%; RCTs, 18.8–46.9%) were consistent with the overall confidence estimates (95% confidence interval [CI]) of 9.3 (8.6–10.2) months and 27.9% (24.2–32.0), respectively. Reported mOS showed greater variation in RWD (6.8–33.2 months) compared with RCTs (21.8–31.5 months), with an overall confidence estimate (95% CI) of 23.0 (19.2–27.6) months. Inspection of funnel plots and sensitivity analyses indicated that there was no publication bias for any efficacy endpoint. Sensitivity analyses showed no evidence of lack of robustness for mPFS, mOS, or ORR. Interpretation of these results is limited by differences in trial design, cohort characteristics, and missing data. Conclusions This novel, comprehensive meta-analysis validates sunitinib as an effective first-line treatment for patients with mRCC in both RCTs and everyday clinical practice. The methodology provides a framework for future analyses combining data from RCTs and RWD.

Abstract
Wide adoption of electronic health records (EHRs) has raised the expectation that data obtained during routine clinical care, termed "real-world" data, will be accumulated across health care systems and analyzed on a large scale to produce improvements in patient outcomes and the use of health care resources. To facilitate a learning health system, EHRs must contain clinically meaningful structured data elements that can be readily exchanged, and the data must be of adequate quality to draw valid inferences. At the present time, the majority of EHR content is unstructured and locked into proprietary systems that pose significant challenges to conducting accurate analyses of many clinical outcomes. This article details the current state of data obtained at the point of care and describes the changes necessary to use the EHR to build a learning health system.

Abstract
Aim: To evaluate how efficacy outcomes from real-world data (RWD) can support those from randomized controlled trials (RCTs), in the context of first-line tyrosine kinase inhibitor treatment of metastatic renal cell carcinoma. Patients & methods: PubMed, Ovid, MEDLINE and EMBASE were searched for RCTs and RWD studies with ≥50 adult patients per arm published in 2000–2017. Outcome measures were median progression-free survival, median overall survival and objective response rate. Results: A total of 13 RCTs and 22 RWD studies met eligibility criteria; 31, 28 and 25 studies, respectively, reported median progression-free survival, median overall survival and objective response rate. Summary outcome measures were similar in RWD and RCTs. Conclusion: RWD validates efficacy-based outcomes from RCTs and may provide supportive evidence to inform clinical decisions.

Abstract
Aim: To assess real-world occurrence of common clinical trial-reported adverse events (AE) among patients with recurrent ovarian cancer initiating niraparib 200 mg/day. Materials & methods: This retrospective observational study used physician-extracted anonymized medical record data of eligible patients initiating niraparib 200 mg/day after platinum-based chemotherapy. Results: Of 153 patients, 57 (37%) experienced ≥1 of the three most common all-grade AEs within 3 months after niraparib initiation: nausea (16%; grade 3/4: 2%), thrombocytopenia (14%; grade 3/4: 3%) and fatigue (24%; grade 3/4: 3%). In the ENGOT-OV16/NOVA trial, these respective AEs occurred in 74, 61 and 59% of patients. Conclusion: Incidence of common clinical trial-reported AEs was lower among patients initiating niraparib 200 mg/day in real-world practice versus patients initiating niraparib 300 mg/day in ENGOT-OV16/NOVA.

Abstract
BACKGROUND The objective of this study is to describe the use of targeted therapies for the treatment of advanced renal cell carcinoma (RCC) and overall survival (OS) among patients in clinical practice in the Veterans Health Administration (VHA). METHODS A retrospective cohort of 286 patients from 24 VHA Medical Centers diagnosed with advanced clear cell RCC between Fiscal Year (FY) 2010 and FY2014 was followed through September 30, 2016. Among patients who received targeted therapy, we described the medications taken, duration of therapy, and overall survival. We also assessed the effect of the first therapy received on overall survival using Cox Proportional Hazards models. RESULTS There were 66 patients who did not receive therapy for their advanced RCC. Of the 220 treated patients, the mean (sd) number of medications received was 1.9 (1.1). The medications most commonly used first were sunitinib (61.8%), pazopanib (17.3%), and temsirolimus (10.9%). The median duration of first-line therapy was 86 days (interquartile range [IQR] 42, 210). Median total duration of therapy was 159 days (IQR 58, 397). 62.3% of patients had ≥ 1 dose of therapy held or reduced, mainly due to an adverse drug event (ADE). Median survival from the start of treatment to death was 1.08 years (IQR 0.80, 1.31). Finally, receipt of temsirolimus vs sunitinib (HR 1.95 [95%CI 1.09,3.47]) as the first targeted therapy was independently associated with an increased hazard of death. CONCLUSION Our analysis of targeted therapies for advanced RCC in VHA suggests duration of treatment is shorter in a real-world setting than in clinical trials, and dose reductions and ADEs are more common.

Abstract
The programmed death-1 inhibitor pembrolizumab has demonstrated efficacy and safety in clinical trials for treating advanced (unresectable/metastatic) melanoma. We investigated the real-world utilization of pembrolizumab and associated patient outcomes for advanced melanoma in US community oncology practices. This retrospective, observational study used deidentified data from electronic health records for adult patients with advanced melanoma who received pembrolizumab at The US Oncology Network sites from September 2014 through December 2015, with follow-up through September 2016. Patients enrolled in clinical trials were excluded. Overall survival (OS) and physician-stated progression-free survival (PFS) were analyzed from pembrolizumab initiation using Kaplan-Meier, and associations between pembrolizumab therapy and OS/PFS, using multivariable Cox regression. Of 168 patients studied, 110 (65%) were male; the median age was 66 years (range, 26–over 90). Pembrolizumab was prescribed as first-line, second-line, and third-line/later for 39 (23%), 87 (52%), and 42 (25%) patients, respectively. In total, 41 patients (24%) had brain metastases. At pembrolizumab initiation, 21/129 (16%) had Eastern Cooperative Oncology Group performance status (ECOG PS) >1; 51/116 (44%) had elevated lactate dehydrogenase. Median follow-up was 10.5 months (range, 0–25.1); median OS was 19.4 months (95% confidence interval, 14.0–not reached); median PFS was 4.2 months (95% confidence interval, 2.9–5.3). Brain metastases, ECOG PS>1, elevated lactate dehydrogenase, and third-line/later (vs. first-line) pembrolizumab were significant predictors (P<0.01) of decreased survival. Treatment-related toxicity was a discontinuation reason for 25% (29/117) of patients, and for 10 of these 29 patients (6% of the full-study cohort) treatment-related toxicity was the only reported reason. The real-world effectiveness and safety of pembrolizumab for advanced melanoma are consistent with clinical trial findings.

Abstract
The use of data from the real world to address clinical and policy-relevant questions that cannot be answered using data from clinical trials is garnering increased interest. Indeed, data from cancer registries and linked treatment records can provide unique insights into patients, treatments and outcomes in routine oncology practice. In this Review, we explore the quality of real-world data (RWD), provide a framework for the use of RWD and draw attention to the methodological pitfalls inherent to using RWD in studies of comparative effectiveness. Randomized controlled trials and RWD remain complementary forms of medical evidence; studies using RWD should not be used as substitutes for clinical trials. The comparison of outcomes between nonrandomized groups of patients who have received different treatments in routine practice remains problematic. Accordingly, comparative effectiveness studies need to be designed and interpreted very carefully. With due diligence, RWD can be used to identify and close gaps in health care, offering the potential for short-term improvement in health-care systems by enabling them to achieve the achievable.

Abstract
BACKGROUND Treatment decisions in routine clinical practice are based on reports of clinical trials, which represent highly selected populations. Limited studies reported real-world evidences representing routine clinical practices in patients with renal-cell carcinoma (RCC) in Europe. The aim of this retrospective, noninterventional chart review was to collect data on the treatment landscape for patients with advanced/metastatic RCC in routine clinical practice in a broader patient population in Austria. PATIENTS AND METHODS Patients with advanced/metastatic RCC receiving systemic treatment between June 2010 and June 2016 across 12 centers in Austria were included. Parameters were entered into an electronic case report form from the participating sites via the application Hermesoft electronic data capture system. Progression-free survival (PFS) and overall survival (OS) were the 2 primary end points. RESULTS The median PFS and OS were 12 months and 44 months, respectively (first-line PFS was 14 months for pazopanib and 13 months for sunitinib; first-line OS was 44 months for pazopanib and 48 months for sunitinib). Factors influencing the OS were sex, with female patients at a significantly higher risk than male patients (hazard ratio = 1.719), Eastern Cooperative Oncology Group performance status > 0 increased the risk twice (hazard ratio = 2.048), and number of metastases > 3 before the first line doubled the risk compared to metastases (hazard ratio = 2.064). CONCLUSION OS in this retrospective chart review was considerably longer than the previous reports in real-world patients, underlining the benefit of current RCC treatment options in routine clinical practice.

Abstract
AIMS Strict oncology clinical trial eligibility criteria can contribute to low accrual and result in poorly generalisable study findings. Using common eligibility criteria, we sought to (i) determine how many patients would be eligible versus ineligible and (ii) describe real-world patterns of treatments and outcomes between those considered trial eligible and ineligible. MATERIALS AND METHODS The Alberta Cancer Registry was used to assemble a population-based cohort of patients diagnosed with 11 common malignancies between 2004 and 2015. We considered age >75 years, anaemia, comorbid conditions (heart disease, uncontrolled diabetes, kidney disease, liver disease) and history of a prior malignancy or immunosuppression to be exclusion criteria. Logistic regression was used to characterise the likelihood of receiving treatment. Cox regression models were constructed to determine cancer-specific and overall survival. RESULTS We identified 125 316 cancer patients, of whom 53% were men; the median age was 66 (interquartile range 48-84) years. Approximately 38% of patients were considered trial ineligible. The most common reasons for ineligibility were advanced age (24%) and heart disease (16%). In this ineligible group, 12, 47 and 19% still underwent chemotherapy, surgery and radiotherapy, respectively. Compared with ineligible patients, eligible patients were more likely to undergo chemotherapy (odds ratio 1.98, 95% confidence interval 1.89-2.07, P < 0.0001), surgery (odds ratio 1.39, 95% confidence interval 1.32-1.46, P < 0.0001) and radiotherapy (odds ratio 1.46, 95% confidence interval 1.4-1.52, P < 0.0001). Compared with ineligible patients who did not receive treatment, those considered ineligible but who still received treatment experienced improved cancer-specific survival (hazard ratio 0.75, 95% confidence interval 0.74-0.77, P < 0.0001) and overall survival (hazard ratio 0.89, 95% confidence interval 0.87-0.90, P < 0.0001). CONCLUSIONS A significant proportion of real-world patients are unable to participate in clinical trials due to stringent exclusion criteria, but many still receive treatment in routine practice. The eligibility criteria of oncology clinical trials should be broadened.

Trends and appropriateness of perioperative chemotherapy for muscle-invasive bladder cancer. Urol Oncol 2019; 37:462-469.

Abstract
INTRODUCTION Contemporary guidelines recommend cystectomy with neoadjuvant or adjuvant cisplatin-based chemotherapy given with curative intent for patients with resectable muscle-invasive bladder cancer (MIBC). However, rates and appropriateness of perioperative chemotherapy utilization remain unclear. We therefore sought to characterize use of perioperative chemotherapy in older radical cystectomy MIBC patients and examine factors associated with use. METHODS Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients with MIBC diagnosed between 2004 and 2013 and treated with radical cystectomy. We classified patients into 3 treatment groups: cystectomy alone, neoadjuvant, or adjuvant chemotherapy. Chemotherapy was classified by regimen. We then fit a multinomial multivariable logistic regression model to assess association between patient factors with the receipt of each treatment. RESULTS We identified 3,826 eligible patients. The majority (484; 65%) received cystectomy alone. Neoadjuvant (676; 18% overall, 69% cisplatin-based), and adjuvant chemotherapy (666, 17% overall, 55% cisplatin-based) were used in similar proportions of cystectomy patients. Over the study period, the odds of receiving adjuvant chemotherapy decreased by 7.5%, whereas neoadjuvant therapy increased by 27.5% (both P < 0.001). There was an increase in use of cisplatin-based regimens in the neoadjuvant setting (35 to 72%, P < 0.001), but not the adjuvant setting. Female gender, lower comorbidity, married status, and lower stage disease were associated with greater odds of receiving neoadjuvant chemotherapy (all P < 0.05). CONCLUSION From 2004 to 2013 use of neoadjuvant chemotherapy for MIBC increased while use of adjuvant chemotherapy decreased. Future studies examining barriers to appropriate chemotherapy use, and the comparative effectiveness of neoadjuvant versus adjuvant chemotherapy are warranted.

Abstract
BACKGROUND Real-world data are essential to accurately assessing efficacy and toxicity of approved agents in everyday practice. PRINCIPAL, a prospective, observational study, was designed to confirm the real-world safety and efficacy of pazopanib in patients with advanced renal cell carcinoma (RCC). SUBJECTS, MATERIALS, AND METHODS Patients with clear cell advanced/metastatic RCC and a clinical decision to initiate pazopanib treatment within 30 days of enrollment were eligible. Primary objectives included progression-free survival (PFS), overall survival (OS), objective response rate (ORR), relative dose intensity (RDI) and its effect on treatment outcomes, change in health-related quality of life (HRQoL), and safety. We also compared characteristics and outcomes of clinical-trial-eligible (CTE) patients, defined using COMPARZ trial eligibility criteria, with those of non-clinical-trial-eligible (NCTE) patients. Secondary study objectives were to evaluate clinical efficacy, safety, and RDI in patient subgroups. RESULTS Six hundred fifty-seven patients were enrolled and received ≥1 dose of pazopanib. Median PFS and OS were 10.3 months (95% confidence interval [CI], 9.2-12.0) and 29.9 months (95% CI, 24.7 to not reached), respectively, and the ORR was 30.3%. HRQoL showed no or little deterioration over time. Treatment-related serious adverse events (AEs) and AEs of special interest occurred in 64 (9.7%), and 399 (60.7%) patients, respectively. More patients were classified NCTE than CTE (85.2% vs. 14.8%). Efficacy of pazopanib was similar between the two groups. CONCLUSION PRINCIPAL confirms the efficacy and safety of pazopanib in patients with advanced/metastatic RCC in a real-world clinical setting. IMPLICATIONS FOR PRACTICE PRINCIPAL is the largest (n = 657) prospective, observational study of pazopanib in patients with advanced/metastatic renal cell carcinoma, to the authors' knowledge. Consistent with clinical trial results that often contain specific patient types, the PRINCIPAL study demonstrated that the effectiveness and safety of pazopanib is similarly safe and effective in patients with advanced kidney cancer in a real-world clinical setting. The PRINCIPAL study showed that patients with advanced kidney cancer who are treated with first-line pazopanib generally do not show disease progression for approximately 10 months and generally survive for nearly 30 months.

Abstract
BACKGROUND Evidence from cancer clinical trials has strong internal validity but can be difficult to generalize to real-world patient populations. Here we analyzed real-world outcomes of patients with metastatic non-small cell lung cancer (mNSCLC) treated with programmed cell death protein 1 (PD-1) inhibitors in the first year following U.S. regulatory approval. MATERIALS AND METHODS This retrospective study leveraged electronic health record (EHR) data collected during routine patient care in community cancer care clinics. The cohort included patients with mNSCLC who had received nivolumab or pembrolizumab for metastatic disease (n = 1,344) with >1 EHR-documented visit from January 1, 2011, to March 31, 2016. Patients with a > 90-day gap between advanced disease diagnosis and first EHR structured data entry were excluded. RESULTS Estimated median overall survival (OS) was 8.0 months (95% confidence interval 7.4-9.0 months). Estimated median OS was 4.7 months (3.4-6.6) for patients with anaplastic lymphoma kinase rearrangement- and epidermal growth factor receptor mutation-positive tumors, and 8.6 months (7.7-10.6) for patients without such mutations. Age at PD-1 inhibitor initiation or line of therapy did not impact OS. CONCLUSION This analysis suggests OS in real-world patients may be shorter than in conventional clinical trial patient cohorts, potentially due to narrow trial eligibility criteria. The lack of difference in OS by line of therapy or age at immunotherapy initiation suggests sustained benefit of PD-1 inhibitors in multitreated patients with mNSCLC and that age is not a predictor of outcome. Further studies are underway in patients with comorbidities, organ dysfunction, and multiple prior therapies. IMPLICATIONS FOR PRACTICE This study evaluated data derived from electronic health records of patients with metastatic non-small cell lung cancer treated with programmed cell death protein 1 (PD-1) inhibitors in the year following regulatory approval. This real-world cohort had shorter overall survival (OS) indexed to PD-1 inhibitor initiation than reported in clinical trials. Late-line treatment did not influence OS, and patients aged >75 at immunotherapy initiation did not have worse outcomes than younger patients. As new therapies enter clinical practice, real-world data can complement clinical trial evidence providing information on generalizability and helping inform clinical treatment decisions.

Abstract
AIM To describe recent evolution in treatment patterns and outcomes for advanced melanoma (AMel). METHODS This retrospective observational study analyzed de-identified electronic health record data from the Flatiron Health database for 1140 adult patients who initiated first-line therapy for AMel from 1 January 2014 to 30 June 2016 with follow-up through 28 February 2017. RESULTS The most common first-line regimens were ipilimumab-based therapies (34%), anti-PD-1 monotherapy (26%) and BRAF/MEK inhibitor(s) (20%). First-line ipilimumab-based and BRAF inhibitor regimens decreased after the third quarter of 2014 (3Q2014), and by 2Q2016, 55 and 91% of BRAF-mutant and BRAF wild-type cohorts, respectively, received a first-line anti-PD-1 regimen. Median overall survival from first-line initiation for all patients was 18.8 months (95% CI: 16.3-23.3). CONCLUSION Results illustrate changing paradigms of therapy and real-world patient outcomes for AMel.

Abstract
Importance The US Food and Drug Administration (FDA) is increasing its pace of approvals for novel cancer therapeutics, including for immune checkpoint inhibitors of programmed cell death 1 protein (anti-PD-1 agents). However, little is known about how quickly anti-PD-1 agents agents reach eligible patients in practice or whether such patients differ from those studied in clinical trials that lead to FDA approval (pivotal clinical trials). Objectives To assess the speed with which anti-PD-1 agents agents reached eligible patients in practice and to compare the ages of patients treated in clinical practice with the ages of those treated in pivotal clinical trials. Design, Setting, and Participants This retrospective cohort study, performed from January 1, 2011, through August 31, 2016, included patients from the Flatiron Health Network who were eligible for anti-PD-1 agents treatment of selected cancer types, which included melanoma, non-small cell lung cancer (NSCLC), and renal cell carcinoma (RCC). Main Outcomes and Measures Cumulative proportions of eligible patients receiving anti-PD-1 agents treatment and their age distributions. Results The study identified 3089 patients who were eligible for anti-PD-1 agents treatment (median age, 66 [interquartile range, 56-75] years for patients with melanoma, 66 [interquartile range, 58-72] years for patients with RCC, and 67 [interquartile range, 59-74] years for patients with NSCLC; 1742 male [56.4%] and 1347 [43.6%] female; 2066 [66.9%] white). Of these patients, 2123 (68.7%) received anti-PD-1 agents treatment, including 439 eligible patients with melanoma (79.1%), 1417 eligible patients with NSCLC (65.6%), and 267 eligible patients with RCC (71.2%). Within 4 months after FDA approval, greater than 60% of eligible patients in each cohort had received anti-PD-1 agents treatment. Overall, similar proportions of older and younger patients received anti-PD-1 agents treatment during the first 9 months after FDA approval. However, there were significant differences in age between clinical trial participants and patients receiving anti-PD-1 agents treatment in clinical practice, with more patients being older than 65 years in clinical practice (range, 327 of 1365 [60.6%] to 46 of 72 [63.9%]) than in pivotal clinical trials (range, 38 of 120 [31.7%] to 223 of 544 [41.0%]; all P < .001). Conclusions and Relevance Anti-PD-1 agents rapidly reached patients in clinical practice, and patients treated in clinical practice differed significantly from patients treated in pivotal clinical trials. Future actions are needed to ensure that rapid adoption occurs on the basis of representative trial evidence.
