Abstract
Tumor immunotherapy is an important clinical strategy for the treatment of various solid and hematological malignancies, and its use is on the rise. Immune checkpoint inhibitors (ICIs) are immunotherapies that boost anticancer immune responses by targeting receptors on the surface of T-lymphocytes. Two important ICIs are anti-programmed death ligand-1 (anti-PD-L1) monoclonal antibodies and anti-cytotoxic T-lymphocyte-associated antigen-4 (anti-CTLA-4) monoclonal antibodies. Tremelimumab (anti-CTLA-4) and durvalumab (anti-PD-L1) have been shown to be effective monotherapies. However, their combination has demonstrated effective and encouraging antitumor activity with manageable safety in patients with unresectable hepatocellular carcinoma. We present the case of an 80-year-old male with hepatocellular carcinoma who had undergone drug-eluting bead transarterial chemoembolization (DEB-TACE) on three occasions and had been started on a combination of ICIs, durvalumab, and tremelimumab. He subsequently developed various immune-related adverse effects in different organ systems, including hepatic and cardiovascular complications. Appropriate treatment was administered, but ultimately, he passed away. We aim to discuss the initial evaluation for suspected immune-related adverse events, specifically those related to myocarditis and its various manifestations, prognosis, and treatment.

Front Pharmacol 2023; 14:1163381. [PMID: 37547328 PMCID: PMC10398575 DOI: 10.3389/fphar.2023.1163381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 07/10/2023] [Indexed: 08/08/2023] Open
Abstract
Importance: In the open-label phase III POSEIDON randomized clinical trial (RCT), a limited course of tremelimumab plus durvalumab and chemotherapy (T + D + CT) indicated in the first-line treatment of metastatic non-small cell lung cancer (mNSCLC), progression-free survival, and overall survival (OS) were substantially improved without significant additional tolerance burden compared to chemotherapy (CT). However, given the high cost of T + D + CT, its value needs to be evaluated in terms of both potency and cost. Objective: To evaluate the cost-effectiveness of T + D + CT versus CT in individuals with previously untreated mNSCLC from a U.S. payer perspective. Design, setting, and participants: A three-state Markov model was adopted to weigh the lifetime costs and effectiveness of T + D + CT versus CT for the treatment of first-line mNSCLC, according to the results of the POSEIDON phase III RCT involving 675 individuals with mNSCLC. Individuals were simulated to undergo either T + D + CT for up to four 21-day cycles, followed by durvalumab once every 4 weeks until disease progression or unacceptable toxic effects and one additional tremelimumab dose, or CT for up to six 21-day cycles (with or without pemetrexed maintenance; all groups) in the analysis. Main outcomes and measures: Lifetime costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) were evaluated with a willingness-to-pay (WTP) threshold of $ 100,000 to $ 150,000 per QALY. The uncertainty of the model was investigated using univariate and probabilistic sensitivity analysis. Results: T + D + CT produced additional 0.36 QALYs with additional costs of $ 217,694, compared to CT, giving rise to ICERs of $ 608,667.86/QALY. The univariate sensitivity analysis demonstrated that the outcomes were most sensitive to the cost of durvalumab. Other variables with a large or moderate influence were the utility of progression-free survival state, utility of progressive disease state, and cost of tremelimumab. Probability sensitivity analysis revealed that T + D + CT had a 0% probability of cost-effectiveness in individuals with mNSCLC at a willingness-to-pay threshold of $ 100,000 to $ 150,000 per QALY. Conclusion and relevance: In this model, T + D + CT was estimated to be less cost-effective than CT for patients with mNSCLC at a WTP threshold of $ 100,000 to $ 150,000 per QALY in the United States. When new combination therapies with remarkable effect become pivotal in the first-line treatment, the price reduction of durvalumab and tremelimumab may be necessary to achieve cost-effectiveness in future possible context.

Abstract
Introduction The introduction of consolidation immunotherapy after chemoradiotherapy has improved outcome for patients with locally advanced non-small cell lung cancer. However, not all patients receive this treatment. This study identifies factors associated with failure to start durvalumab as consolidation therapy with the aim of optimizing treatment, supportive care and prehabilitation to ensure that more patients complete the planned treatment. Materials and methods Patients from two clinical trials and a named patient use program, were included in this study. All patients received platinum-doublet chemotherapy concomitant with radiotherapy to a total dose of 60-66 gray. Patient characteristics, cancer treatment, toxicity, performance status and laboratory data before and after chemoradiotherapy were recorded and patients who never started durvalumab were compared with those who did. Results A total of 101 patients were included, of which 83 started treatments with durvalumab after chemoradiotherapy. The 18 patients who did not start durvalumab had significantly higher lactate dehydrogenase at baseline and a worse performance status, cumulative toxicity and higher c-reactive protein after completed chemoradiotherapy. Data also suggest that pre-treatment diabetes and reduced hemoglobin and/or diffusion capacity of the lungs for carbon monoxide contribute to the risk of treatment abruption. Conclusion Treatment plan disruption rate was 18%. Systemic inflammation and performance status were associated with failure to receive durvalumab after chemoradiation. Further studies are needed to confirm findings and prospective trials should investigate whether prehabilitation and supportive treatment could help more patients finishing the planned treatment.

Abstract
Introduction The standard of care for patients with unresectable stage III non-small cell lung cancer (NSCLC) is chemoradiotherapy (CRT) followed by consolidation durvalumab as shown in the PACIFIC trial. The purpose of this study is to evaluate clinical outcomes and toxicities regarding the use of durvalumab in a real clinical scenario. Methods A single-center retrospective study was conducted on patients with a diagnosis of unresectable stage III NSCLC who underwent radical CRT followed or not by durvalumab. Tumor response after CRT, pattern of relapse, overall survival (OS) and progression-free survival (PFS), and toxicity profile were investigated. Results Eighty-five patients met the inclusion criteria. The median age was 67 years (range 45-82 years). Fifty-two patients (61.2%) started sequential therapy with durvalumab. The main reason for excluding patients from the durvalumab treatment was the expression of PD-L1 < 1%. Only two patients presented a grade 4 or 5 pneumonitis. A median follow-up (FU) of 20 months has been reached. Forty-five patients (52.9%) had disease progression, and 21 (24.7%) had a distant progression. The addition of maintenance immunotherapy confirmed a clinical benefit in terms of OS and PFS. Two-year OS and PFS were respectively 69.4% and 54.4% in the durvalumab group and 47.9% and 24.2% in the no-durvalumab group (p = 0.015, p = 0.007). Conclusion In this real-world study, patients treated with CRT plus durvalumab showed clinical outcomes and toxicities similar to the PACIFIC results. Maintenance immunotherapy after CRT has been shown to be safe and has increased the survival of patients in clinical practice.

Abstract
INTRODUCTION Since 2016, the progressive use of immune checkpoint inhibitors (ICIs) starting from second-line treatment has led to an improvement in overall survival in locally advanced and metastatic urothelial cancer (UC). Clinical trials are underway testing the role of ICIs since the first stages of the disease, alone or in combination with standard therapies. AREAS COVERED This review summarizes the current updated evidence regarding the role of ICIs in the different stages of UC, the ongoing clinical trials exploring the potential benefit of immunotherapy alone or in combination with standard-of-care therapies, as well as the promising association of ICIs with antibody-drug conjugates (ADCs). EXPERT OPINION In the first-line setting, ICIs alone in platinum-unfit patients have shown unconvincing results; the ongoing EV-302 trial will probably suggest enfortumab vedotin plus pembrolizumab as a new effective option. The optimal duration of maintenance immunotherapy is still to be determined, finding a balance with the risk-benefit profile. The clinical benefit of ICIs as second-line treatment is limited to a subset of patients that cannot be definitively established yet. In the next 5 years, a lot of new ADCs will likely emerge for the treatment of UC.

Efficacy and safety of durvalumab + chemotherapy vs. atezolizumab + chemotherapy in the treatment of small‑cell lung cancer: a retrospective comparative cohort study. J Thorac Dis 2023; 15:3339-3349.

Abstract
Background Durvalumab and atezolizumab have recently been approved in extensive small cell lung cancer (SCLC) with moderate median overall survival (OS) improvements. However, only limited data exist regarding the impact of immunotherapy in real-world SCLC patients. This study sought to assess the efficacy and safety of atezolizumab plus chemotherapy and durvalumab plus chemotherapy in the treatment of SCLC in a real-world setting. Methods A retrospective cohort study of all patients treated for SCLC with chemotherapy with PD-L1 inhibitor, at 3 centers in China between February 1, 2020 and April 30, 2022. Patient characteristics, adverse-events and survival analyses were conducted. Results A total of 143 patients were enrolled in this study, 100 were treated with durvalumab and the remainder with atezolizumab. The baseline characteristics of the two groups were fundamentally balanced before using PD-L1 inhibitors (P>0.05). The median OS (mOS) of the patients who received durvalumab or atezolizumab as the first-line treatment were 22.0 and 10.0 months, respectively (P=0.03). Survival analysis of patients with brain metastasis (BM) revealed that the median progression-free survival (mPFS) of patients without BM treated with durvalumab plus chemotherapy (5.5 months) was longer than that of those with BM (4.0 months) (P=0.03). In contrast, in the atezolizumab plus chemotherapy regimen, BM did not affect survival. In addition, the addition of radiotherapy to treatment with PD-L1 inhibitors in combination with chemotherapy has a tendency to improve long-term survival. As for safety analysis, there was no significant difference in the incidence of immune-related adverse events (IRAEs) during PD-L1 inhibitor therapy between the 2 groups (P>0.05). And during treatment with immunochemotherapy, radiotherapy was not associated with the development of IRAE (P=0.42) but increased the risk of immune-related pneumonitis (P=0.026). Conclusions The implication of this study for clinical practice is a preference for durvalumab in first-line immunotherapy for SCLC. In addition, appropriate radiotherapy during treatment with PD-L1 inhibitors in combination with chemotherapy may prolong long-term survival, but the occurrence of immune-related pneumonitis should be vigilant. Data from this study are limited and the baseline characteristics of the two populations still need to be more finely classified.

Abstract
We conducted a phase Ib study to examine the safety of a combination of carbon-ion RT (CIRT) with durvalumab (MEDI4736; AstraZeneca) in patients with locally advanced cervical cancer. This was an open-label, single-arm study with a modified 3 + 3 design. Patients with newly diagnosed histologically proven locally advanced cervical cancer were enrolled. All patients received 74.4 Gy of CIRT in 20 fractions and concurrent weekly cisplatin (chemo-CIRT) at a dose of 40 mg/m2. Durvalumab was administered (1500 mg/body) at weeks two and six. The primary endpoint was the incidence of adverse events (AEs) and serious AEs (SAEs), including dose-limiting toxicity (DLT). All three enrolled patients completed the treatment without interruption. One patient developed hypothyroidism after treatment and was determined to be an SAE. No other SAEs were observed. The patient recovered after levothyroxine sodium hydrate treatment. None of the AEs, including hypothyroidism, were associated with DLT in the present study. All three patients achieved complete responses within the CIRT region concerning treatment efficacy. This phase 1b trial demonstrates the safety of combining chemo-CIRT and durvalumab for locally advanced cervical cancer in the early phase. Further research is required as only three patients were included in this study.

Abstract
Aim: We investigated the effectiveness of durvalumab post-concurrent CRT (cCRT) and post-sequential CRT (sCRT) versus cCRT and sCRT alone and compared these outcomes with the PACIFIC trial. Methods: Four cohorts of stage III NSCLC patients who received CRT were included: cCRT with and without durvalumab, sCRT with and without durvalumab. PFS and OS were analyzed using Cox regression. Results: Durvalumab improved PFS (cCRT: aHR = 0.69, sCRT: aHR = 0.71) and OS (cCRT: aHR = 0.71, sCRT: aHR = 0.32), although not all results were significant. PFS was longer in the real-world than in the trial, while OS did not differ. Conclusion: Durvalumab after CRT improved the survival outcomes. The difference between PFS in our study and the trial may be due to differences in follow-up methods.

Abstract
This report presents a remarkable and unusual case of extrapulmonary small cell carcinoma (EPSCC) occurring in the prostate of a 77-year-old male patient with a previous history of prostate adenocarcinoma and multiple metastases. EPSCC is a highly aggressive form of cancer that often results in unfavorable survival outcomes, posing significant challenges in terms of management due to the absence of established treatment protocols. Despite receiving standard treatment including bicalutamide and leuprorelin, the patient's condition showed no improvement. Consequently, the medical team made the decision to administer a carboplatin-etoposide chemotherapy regimen along with durvalumab, drawing upon the efficacy observed in similar treatment approaches for small cell carcinoma of the lung. This case highlights the critical need for further research and clinical trials to establish optimal treatment strategies for EPSCC affecting the prostate. By enhancing our understanding of this rare malignancy, we can potentially improve patient outcomes and develop targeted therapies tailored to its aggressive nature.

Abstract
A 69-year-old Japanese male with advanced lung adenocarcinoma developed neurological symptoms after chemoradiotherapy and durvalumab maintenance therapy. He was positive for serum antiamphiphysin antibody, which is rarely seen in patients with lung adenocarcinoma. Additionally, his brain magnetic resonance images showed limbic encephalitis which led to the diagnosis of classic paraneoplastic neurological syndrome (PNS). Immune checkpoint inhibitors (ICIs) activate T cells and may also activate antineuronal antibodies that cause PNS. Durvalumab, which is an ICI, may have led to antiamphiphysin antibody-positive PNS in our patient. Treatment with systemic high-dose methylprednisolone was unsuccessful and he died 2 months later. PNS should be considered as one of the differential diagnoses in patients with lung cancer and neurological symptoms during, or after, ICI treatment.

Abstract
Introduction: Combined immune checkpoint inhibitors can cause gastrointestinal adverse events. Methods: We performed a meta-analysis of pooled colonic, hepatic and pancreatic treatment-related adverse events of combined ICI. Results: 53 trials reporting treatment-related adverse events in 6581 patients. All grade diarrhea was the most common adverse event seen in 25.4% patients, followed by all grade hepatitis in nearly 13% patients and pancreatitis in nearly 7.5% patients. Conclusion: Our study provides pooled data of treatment-related adverse events from different combination immune checkpoint inhibitors use in solid tumors and demonstrates a high incidence of all grades and ≥3 grade gastrointestinal adverse events. Further studies are required to characterize these adverse events and assess their overall impact on treatment course and outcomes.

Abstract
Immune checkpoint inhibitors are increasingly used in combination with chemotherapy for the treatment of non-small cell lung cancer, yet the success of combination therapies is relatively limited. Thus, more detailed insight regarding the tumor molecular markers that may affect the responsiveness of patients to therapy is required. Here, we set out to explore the proteome of two lung adenocarcinoma cell lines (HCC-44 and A549) treated with cisplatin, pemetrexed, durvalumab, and the corresponding mixtures to establish the differences in post-treatment protein expression that can serve as markers of chemosensitivity or resistance. The mass spectrometry study showed that the addition of durvalumab to the treatment mixture resulted in cell line- and chemotherapeutic agent-dependent responses and confirmed the previously reported involvement of DNA repair machinery in the potentiation of the chemotherapy effect. Further validation using immunofluorescence also indicated that the potentiating effect of durvalumab in the case of cisplatin treatment was dependent on the tumor suppressor RB-1 in the PD-L1 weakly positive cells. In addition, we identified aldehyde dehydrogenase ALDH1A3 as the general putative resistance marker. Further studies in patient biopsy samples will be required to confirm the clinical significance of these findings.

Abstract
Background The optimal first-line immune checkpoint inhibitor (ICI) treatment strategy for metastatic or early triple-negative breast cancer (TNBC) has not yet been determined as a result of various randomized controlled trials (RCTs). The purpose of this study was to compare the efficacy and safety of ICIs in patients with metastatic or early TNBC. Methods RCTs comparing the efficacy and safety of ICIs in patients with TNBC were included in the studies. Based on PRISMA guidelines, we estimated pooled hazard ratios (HRs) and odds ratios (ORs) using random-effects models of Bayesian network meta-analysis. Primary outcomes were progression-free survival (PFS) and overall survival (OS). Secondary outcomes included pathologic complete response rate (pCR), grade ≥ 3 treatment-related adverse events (trAEs), immune-related adverse events (irAEs), and grade ≥ 3 irAEs. Results The criteria for eligibility were met by a total of eight RCTs involving 4,589 patients with TNBC. When ICIs were used in patients without programmed death-ligand 1 (PD-L1) selection, there was a trend toward improved PFS, OS, and pCR, without significant differences. Pembrolizumab plus chemotherapy is superior to other treatment regimens in terms of survival for TNBC patients based on Bayesian ranking profiles. Subgroup analysis by PD-L1 positive population indicated similar results, and atezolizumab plus chemotherapy provided better survival outcomes. Among grade ≥ 3 trAEs and any grade irAEs, there was no statistically significant difference among different ICI agents. The combination of ICIs with chemotherapy was associated with a higher incidence of grade ≥ 3 irAEs. Based on rank probability, the ICI plus chemotherapy group was more likely to be associated with grade ≥ 3 trAEs, any grade irAEs, and grade ≥ 3 irAEs. Hypothyroidism and hyperthyroidism were the most frequent irAEs in patients receiving ICI. Conclusions ICI regimens had relatively greater efficacy and safety profile. Pembrolizumab plus chemotherapy and atezolizumab plus chemotherapy seem to be superior first-line treatments for intention-to-treat and PD-L1-positive TNBC patients, respectively. It may be useful for making clinical decisions to evaluate the efficacy and safety of different ICIs based on our study.

Abstract
INTRODUCTION While first-line immunotherapy approaches are standard, in patients with NSCLC previously treated with PD-1 or PD-L1 (PD-[L]1) inhibitors, the activity of combined CTLA-4 plus PD-L1 inhibition is unknown. This phase 1b study evaluated the safety and efficacy of durvalumab plus tremelimumab in adults with advanced NSCLC who received anti-PD-(L)1 monotherapy as their most recent line of therapy. METHODS Patients with PD-(L)1-relapsed/refractory NSCLC were enrolled between October 25, 2013, and September 17, 2019. Durvalumab 20 mg/kg plus tremelimumab 1 mg/kg was administered intravenously every 4 weeks (Q4W) for 4 doses, followed by 9 doses of durvalumab monotherapy Q4W for 12 months or disease progression. Primary endpoints included safety and objective response rate (ORR) based on RECIST version 1.1 per blinded independent central review (BICR); secondary endpoints were ORR based on RECIST 1.1 per investigator; duration of response, disease control, and PFS based on RECIST v1.1 per BICR and investigator; and OS. RESULTS PD-[L]1-refractory (n=38) and PD[L]1-relapsed (n=40) patients were treated. The most common treatment-related adverse events (TRAEs) were fatigue (26.3%, PD-[L]1-refractory patients) and diarrhea (27.5%, PD-[L]1-relapsed patients). Grade 3-4 TRAEs occurred in 22 patients. Median follow-up duration was 43.6 months for PD-(L)1-refractory patients and 41.2 months for PD-(L)1-relapsed patients. The ORR was 5.3% for PD-(L)1-refractory patients (1 complete response, 1 partial response) and 0% for PD-(L)1-relapsed patients. CONCLUSIONS Durvalumab plus tremelimumab had a manageable safety profile, but the combination did not show efficacy following PD-(L)1 treatment failure.

Abstract
Programmed cell death protein 1/programmed cell death ligand 1 (PD-1/PD-L1) checkpoint inhibitors have been on the front line of clinical revolution in which, the targeted PD-L1 therapy has obtained some success in patients with solid tumors. A large number of clinical trials revealed that both monotherapy and combination therapy of PD-L1 antibody significantly suppress some tumor growth and promote the survival of patients. At present, anti-PD-L1 treatment has been used as a portion of standard treatment for lung cancer, breast cancer, head and neck squamous cell carcinoma, and urothelial carcinoma. Although much evidence has demonstrated that PD-L1 antibody is safe in most patients, there are still some adverse reactions, such as pneumonitis, hepatitis, colitis, neurologic events and myocarditis. In this review, the clinical information, including the efficacy and safety of durvalumab in solid tumors, was enumerated and summarized at this stage to grasp the current application of targeted PD-L1 therapy and provide guidance for clinical application.

Abstract
Following the practice-changing results observed in several hematological and solid tumors, immunotherapy with immune checkpoint inhibitors (ICIs) has been tested in cholangiocarcinoma (CCA) patients. However, ICI monotherapy has had disappointing results in CCA, and phase I-III clinical trials have assessed whether combinatorial strategies including immunotherapy plus other anticancer agents may have a synergistic activity. The TOPAZ-1 trial has recently highlighted improved survival in CCA patients receiving first-line durvalumab plus gemcitabine-cisplatin compared with gemcitabine plus cisplatin alone, and several guidelines consider adding durvalumab to the reference doublet as standard of care. This article provides an overview of durvalumab pharmacology, safety and efficacy in CCA, highlighting current and future research directions in this setting.

A Propensity-Matched Retrospective Comparative Study with Historical Control to Determine the Real-World Effectiveness of Durvalumab after Concurrent Chemoradiotherapy in Unresectable Stage III Non-Small Cell Lung Cancer. Cancers (Basel) 2023; 15:cancers15051606. [PMID: 36900397 PMCID: PMC10000649 DOI: 10.3390/cancers15051606] [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: 02/05/2023] [Revised: 03/01/2023] [Accepted: 03/03/2023] [Indexed: 03/08/2023] Open
Abstract
This study aimed to add real-world evidence to the literature regarding the effectiveness and safety of durvalumab consolidation (DC) after concurrent chemoradiotherapy (CCRT) in the treatment of unresectable stage III non-small cell lung cancer (NSCLC). Using a hospital-based NSCLC patient registry and propensity score matching in a 2:1 ratio, we conducted a retrospective cohort study of patients with unresectable stage III NSCLC who completed CCRT with and without DC. The co-primary endpoints were 2-year progression-free survival and overall survival. For the safety evaluation, we evaluated the risk of any adverse events requiring systemic antibiotics or steroids. Of 386 eligible patients, 222 patients-including 74 in the DC group-were included in the analysis after propensity score matching. Compared with CCRT alone, CCRT with DC was associated with increased progression-free survival (median: 13.3 vs. 7.6 months, hazard ratio[HR]: 0.63, 95% confidence interval[CI]: 0.42-0.96) and overall survival (HR: 0.47, 95% CI: 0.27-0.82) without an increased risk of adverse events requiring systemic antibiotics or steroids. While there were differences in patient characteristics between the present real-world study and the pivotal randomized controlled trial, we demonstrated significant survival benefits and tolerable safety with DC after the completion of CCRT.

[PMID: 36535565 DOI: 10.1016/j.annonc.2022.12.008] [Citation(s) in RCA: 19] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 12/07/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) have a poor prognosis. The phase III KESTREL study evaluated the efficacy of durvalumab [programmed death-ligand 1 (PD-L1) antibody] with or without tremelimumab [cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody], versus the EXTREME regimen in patients with R/M HNSCC. PATIENTS AND METHODS Patients with HNSCC who had not received prior systemic treatment for R/M disease were randomized (2 : 1 : 1) to receive durvalumab 1500 mg every 4 weeks (Q4W) plus tremelimumab 75 mg Q4W (up to four doses), durvalumab monotherapy 1500 mg Q4W, or the EXTREME regimen (platinum, 5-fluorouracil, and cetuximab) until disease progression. Durvalumab efficacy, with or without tremelimumab, versus the EXTREME regimen in patients with PD-L1-high tumors and in all randomized patients was assessed. Safety was also assessed. RESULTS Durvalumab and durvalumab plus tremelimumab were not superior to EXTREME for overall survival (OS) in patients with PD-L1-high expression [median, 10.9 and 11.2 versus 10.9 months, respectively; hazard ratio (HR) = 0.96; 95% confidence interval (CI) 0.69-1.32; P = 0.787 and HR = 1.05; 95% CI 0.80-1.39, respectively]. Durvalumab and durvalumab plus tremelimumab prolonged duration of response versus EXTREME (49.3% and 48.1% versus 9.8% of patients remaining in response at 12 months), correlating with long-term OS for responding patients; however, median progression-free survival was longer with EXTREME (2.8 and 2.8 versus 5.4 months). Exploratory analyses suggested that subsequent immunotherapy use by 24.3% of patients in the EXTREME regimen arm contributed to the similar OS outcomes between arms. Grade 3/4 treatment-related adverse events (TRAEs) for durvalumab, durvalumab plus tremelimumab, and EXTREME were 8.9%, 19.1%, and 53.1%, respectively. CONCLUSIONS In patients with PD-L1-high expression, OS was comparable between durvalumab and the EXTREME regimen. Durvalumab alone, and with tremelimumab, demonstrated durable responses and reduced TRAEs versus the EXTREME regimen in R/M HNSCC.

Abstract
BACKGROUND Consolidation durvalumab after concurrent chemoradiation is the standard of care for unresectable stage III non-small cell lung cancer (NSCLC) based on the PACIFIC trial. However, there have been reports in the literature suggesting the efficacy of the treatment differs in patients whose tumors harbor epidermal growth factor receptor (EGFR) mutations and in those with low programed death ligand-1 (PD-L1) expression. This study describes the survival outcomes for patients with unresectable stage III NSCLC treated with chemoradiation followed by durvalumab with a specific focus on EGFR mutation status and PD-L1 expression. METHODS This retrospective observational study was conducted across six sites in Greater Sydney, Australia. It included all patients diagnosed with unresectable stage III NSCLC treated with chemoradiation and who received at least one cycle of durvalumab between January 2018 and September 2021. Patients were stratified according to EGFR mutation status and PD-L1 tumor proportion score (TPS) of 1%. RESULTS Of the 145 patients included in the analysis, 15/145 (10%) patients harbored an EGFR mutation and 61/145 (42%) patients had PD-L1 TPS of <1%. At a median follow-up of 15.1 months from the start of durvalumab, median progression-free survival (PFS) in EGFR mutant versus wild-type patients was 7.5 and 33.9 months, respectively (hazard ratio [HR]: 2.7; 95% confidence intervals [95% CI] 1.2-5.7; p = .01). Overall survival (OS) was not different between EGFR mutant and wild-type patients. There was no statistically significant difference in PFS (HR .7, 95% CI .4-1.7, p = .43) or OS (HR .5, 95% CI .4-4.7, p = .16) between patients with PD-L1 TPS of <1% versus PD-L1 TPS of ≥1%. CONCLUSIONS Our data adds to the growing evidence that suggests consolidation durvalumab after definitive chemoradiation may not be as efficacious in patients with EGFR-mutant tumors compared with EGFR wild-type NSCLC.

Abstract
Cutaneous T cell lymphoma (CTCL) is an incurable and cosmetically disfiguring disease associated with microenvironmental signals. We investigated the effects of CD47 and PD-L1 immune checkpoint blockades, as a strategy for targeting both innate and adaptive immunity. CIBERSORT analysis identified the immune cell composition in the CTCL tumor microenvironment and the immune checkpoint expression profile for each immune cell gene cluster from CTCL lesions. We investigated the relationship between MYC and CD47 and PD-L1 expression and found that MYC shRNA knockdown and MYC functional suppression by TTI-621 (SIRPαFc) and anti-PD-L1 (durvalumab) in CTCL cell lines reduced the expression of CD47 and PD-L1 mRNA and protein as measured by qPCR and flow cytometry, respectively. In vitro, blockade of the CD47-SIRPα interaction with TTI-621 increased the phagocytic activity of macrophages against CTCL cells and enhanced CD8+ T-cell-mediated killing in a mixed leucocyte reaction. Moreover, TTI-621 synergized with anti-PD-L1 in macrophages reprogram to M1-like phenotypes and inhibited CTCL cell growth. These effects were mediated by cell‒death-related pathways, including apoptosis, autophagy, and necroptosis. Collectively, our findings demonstrate that CD47 and PD-L1 are critical regulators of immune surveillance in CTCL and dual targeting of CD47 and PD-L1 will provide insight into tumor immunotherapy for CTCL.

Abstract
INTRODUCTION Consolidation durvalumab (the 'PACIFIC regimen') is standard of care for patients with unresectable stage III NSCLC who have not progressed following chemoradiotherapy (CRT), based on data from the phase 3 placebo-controlled PACIFIC study (NCT02125461). However, the benefit of immunotherapy in patients with stage III EGFR-mutant (EGFRm) NSCLC is not well characterized. Here, we report a post-hoc exploratory efficacy and safety analysis from a subgroup of patients with EGFRm NSCLC from PACIFIC. METHODS Patients with stage III unresectable NSCLC and no progression after ≥2 cycles of platinum-based concurrent CRT were randomized (2:1) to receive durvalumab (10 mg/kg intravenously every 2 weeks, for up to 1 year) or placebo; stratified by age, sex and smoking history. Enrollment was not restricted by oncogenic driver gene mutation status or PD-L1 expression. Patients with NSCLC with an EGFR mutation, determined by local testing only, were included in this subgroup analysis. The primary endpoints were progression-free survival (PFS; assessed by blinded independent central review) and overall survival (OS). Secondary endpoints included objective response rate and safety. Statistical analyses for the subgroup of patients with EGFRm NSCLC were post-hoc and considered exploratory. RESULTS Of 713 patients randomized, 35 had locally confirmed EGFRm NSCLC (durvalumab, n = 24; placebo, n = 11). At data cut-off (January 11, 2021), median duration of follow-up for survival was 42.7 months (range: 3.7-74.3) for all randomized patients in the subgroup. Median PFS was 11.2 months (95% confidence interval [CI]: 7.3-20.7) with durvalumab versus 10.9 months (95% CI: 1.9-not evaluable [NE]) with placebo; hazard ratio [HR], 0.91 (95% CI: 0.39-2.13). Median OS was 46.8 months (95% CI: 29.9-NE) with durvalumab versus 43.0 months (95% CI: 14.9-NE) with placebo; HR, 1.02 (95% CI: 0.39-2.63). The safety profile of durvalumab was generally consistent with the overall population and known profile for durvalumab. CONCLUSIONS PFS and OS outcomes with durvalumab were similar to placebo for patients with EGFRm tumors, with wide CIs. These data should be interpreted with caution due to small patient numbers and lack of a prospective study that evaluates clinical outcomes by tumor biomarker status. Further research to determine the optimal treatment for unresectable stage III EGFRm NSCLC is warranted.

Abstract
This is the phase Ib part of the phase I/II CAMILLA trial evaluating cabozantinib plus durvalumab in advanced chemo-refractory proficient mismatch repair or microsatellite stable (pMMR/MSS) gastrointestinal malignancies including gastric/gastroesophageal junction/esophageal (G/GEJ/E) adenocarcinoma, colorectal cancer (CRC), and hepatocellular carcinoma (HCC). Thirty-five patients are enrolled. There are no observed dose-limiting toxicities during dose escalation. The overall grade 3/4 treatment-related adverse event rate is 34%. Among evaluable patients (n = 30), the objective response rate (ORR) is 30%, disease control rate (DCR) 83.3%, 6-month progression-free survival (PFS) 36.7%, median PFS 4.5 months, and median overall survival (OS) 8.7 months. Responses are seen in 4 of 17, 3 of 10, and 2 of 3 patients with CRC, G/GEJ/E adenocarcinoma, and HCC, respectively. Participants with a PD-L1 combined positive score (CPS) ≥5 have numerically higher ORR, PFS, and OS. Cabozantinib plus durvalumab demonstrates a tolerable safety profile and potential efficacy in previously treated advanced pMMR/MSS gastrointestinal malignancies.

Abstract
INTRODUCTION The growing body of real-life data on maintenance treatment with durvalumab suggests that immunological markers of the cancer-host interplay may have significant effects on the efficacy of multimodal therapy in patients with unresectable stage III NSCLC. AREAS COVERED We summarize real-world clinical data regarding this new tri-modal approach and report on potential biomarker landscape. EXPERT OPINION The obvious question posed in this context of a very heterogeneous inoperable stage III NSCLC disease is: How can we augment an ability to predict checkpoint inhibition success or failure? Which tools and biomarkers, which clinical metadata and genetic background are relevant and feasible? No single biomarker will ever fully dominate the unresectable stage III NSCLC space, so we advocate multilevel and multivariate analysis of biomarkers. In this particular opinion piece, we explore the impact of PD-L1 expression on tumor cells, neutrophil-to-lymphocyte ratio, EGFR and STK11 mutational status, interferon-gamma signature, and tumor-infiltrating lymphocytes among others.

Abstract
Objective The TOPAZ-1 trial reported a significant survival benefit of durvalumab in combination with chemotherapy for the first-line treatment of biliary tract cancer (BTC). However, no studies have evaluated the economics of this treatment option. The aim of this study was to assess the cost effectiveness of durvalumab plus chemotherapy compared to placebo plus chemotherapy from the perspective of US and Chinese payers. Methods Based on clinical data from the TOPAZ-1 trial, a Markov model was developed to simulate 10-year life expectancy and total healthcare costs for patients with BTC. The treatment group received durvalumab in combination with chemotherapy and the control group received placebo plus chemotherapy. The primary outcomes analyzed included quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs). Uncertainty in the analysis results was assessed by sensitivity analysis. Results For US payers, the placebo plus chemotherapy group had a total cost of $56,157.05 and a utility of 1.10 QALYs, while the durvalumab plus chemotherapy group had a total cost of $217,069.25, a utility of 1.52 QALYs, resulting in an ICER of $381,864.39/QALY. For Chinese payers, the ICER of durvalumab plus chemotherapy group was $367,608.51/QALY. Sensitivity analysis showed that the analysis was most sensitive to the price of durvalumab. For US and Chinese payers, under the respective willing to pay thresholds, the likelihood of the durvalumab plus chemotherapy arm being cost-effective was 0%. Conclusions Both in China and in the US, durvalumab in combination with chemotherapy is not a cost-effective option for the first-line treatment of BTC compared with chemotherapy.

Abstract
We recruited 50 patients with unresectable stage III NSCLC who received CCRT between March 2020 and March 2021. Durvalumab consolidation (DC) was administered to patients (n = 23) without progression after CCRT and programmed death-ligand 1 (PD-L1) ≥ 1%. Blood samples were collected before (C0) and after CCRT (C1) to calculate PBC counts and analyze CTCs. CTCs, isolated by the CD-PRIMETM system, exhibited EpCAM/CK+/CD45- phenotype in BioViewCCBSTM. At median follow-up of 27.4 months, patients with residual CTC clusters at C1 had worse median PFS than those without a detectable CTC cluster (11.0 vs. 27.8 months, p = 0.032), and this trend was noted only in the DC group (p = 0.034). Patients with high platelets at C1 (PLThi, >252 × 103/µL) had worse median PFS than those with low platelets (PLTlo) (5.9 vs. 17.1 months, p < 0.001). In multivariable analysis, PLThi and residual CTC clusters at C1 were independent risk factors for PFS, and DC group with PLThi and residual CTC clusters at C1 showed the worst median PFS (2.6 months, HR 45.16, p = 0.001), even worse than that of the CCRT alone group with PLThi (5.9 months, HR 15.39, p = 0.001). The comprehensive analysis of CTCs and PBCs before and after CCRT revealed that the clearance of CTC clusters and platelet counts at C1 might be potential biomarkers for predicting survival.

Abstract
BACKGROUND/AIM Efficacy and toxicity of concurrent chemoradiotherapy (CCRT) and durvalumab for locally advanced non-small cell lung cancer (LA-NSCLC) with N3 lymph node metastasis remain unclear. We aimed to evaluate the clinical outcomes of patients who received CCRT and durvalumab (durvalumab cohort) and compare their outcomes with those of patients who received CCRT alone (CCRT-alone cohort). PATIENTS AND METHODS The data of patients who had received treatment between November 2008 and February 2022 and were followed up for at least 3 months were retrospectively analyzed. Local control, progression-free survival, and overall survival were evaluated using Kaplan-Meier analysis and compared using the log-rank test. Toxicity was evaluated using the Common Terminology Criteria for Adverse Events version 5.0. RESULTS The data of 29 patients were analyzed (median follow-up period: 22 months). Among them, 17 received CCRT alone and 12 received CCRT and durvalumab. There were 14 patients with stage IIIB and 15 with stage IIIC LA-NSCLC. The durvalumab cohort (89%) had a significantly higher 1-year local control rate than the CCRT-alone cohort (47%; p=0.035). No significant difference was observed in either progression-free or overall survival between the two cohorts. Grade ≥2 pneumonitis was observed in 6 (50%) and 7 (41%) patients in the durvalumab and CCRT-alone cohorts, respectively. CONCLUSION CCRT with durvalumab may be effective against LA-NSCLC with N3 lymph node metastasis. The incidence of grade 2 pneumonitis was slightly higher in the durvalumab cohort than in the CCRT-alone cohort, suggesting the need for careful patient monitoring after treatment.

Abstract
Gallbladder cancer (GBC) is a relatively infrequent but highly lethal cancer with a poor prognosis. Management remains challenging and controversial, and most patients are diagnosed at an advanced stage. However, with the progressive advances in the use of immunotherapies, new treatment modalities are being implemented. In September 2022, the US FDA approved durvalumab (a PD-L1 inhibitor) in combination with chemotherapy for adult patients with locally advanced or metastatic GBC. This groundbreaking news is the first FDA approval for the use of immunotherapy in biliary tract cancers. This article reviews the newest advances and trials regarding immunotherapy for GBC.

Abstract
BACKGROUND Targeting programmed cell death protein 1 (PD-1) and indoleamine 2,3-dioxygenase (IDO1) pathways is an appealing option for cancer treatment. METHODS The open-label, phase 1/2 ECHO-203 study evaluated the safety, tolerability, and efficacy of the IDO1 inhibitor epacadostat in combination with durvalumab, a human anti-PD-L1 monoclonal antibody in adult patients with advanced solid tumors. RESULTS The most common treatment-related adverse events were fatigue (30.7%), nausea (21.0%), decreased appetite (13.1%), pruritus (12.5%), maculopapular rash (10.8%), and diarrhea (10.2%). Objective response rate (ORR) in the overall phase 2 population was 12.0%. Higher ORR was observed in immune checkpoint inhibitor (CPI)-naïve patients (16.1%) compared with patients who had received previous CPI (4.1%). Epacadostat pharmacodynamics were evaluated by comparing baseline kynurenine levels with those on therapy at various time points. Only the 300-mg epacadostat dose showed evidence of kynurenine modulation, albeit unsustained. CONCLUSIONS Epacadostat plus durvalumab was generally well tolerated in patients with advanced solid tumors. ORR was low, and evaluation of kynurenine concentration from baseline to cycle 2, day 1, and cycle 5, day 1, suggested >300 mg epacadostat twice daily is needed to ensure sufficient drug effect. CLINICAL TRIAL INFORMATION A study of epacadostat (INCB024360) in combination with durvalumab (MEDI4736) in subjects with selected advanced solid tumors (ECHO-203) (NCT02318277).

Abstract
Stage III non-small-cell lung cancer (NSCLC) represents a heterogeneous group of disease entities with multimodality treatments. For most patients, platinum-based doublet with concurrent chemoradiotherapy (CRT) has become the first-choice treatment over the past decade. Immune checkpoint inhibition has revolutionized the management of metastatic NSCLC; however, no major advances in systemic therapy for Stage III NSCLC have been made. The following report is the case of a patient with unresectable Stage IIIA NSCLC successfully treated with durvalumab. The patient completed 1 year of treatment without interruptions, and disease control has been maintained for more than 20 months since the start of durvalumab.

Abstract
Penile squamous cell carcinoma is a rare disease entity with poor overall survival in an advanced stage. Few studies have investigated the role of immunotherapy in advanced penile squamous cell carcinoma. Herein, we report a case of stage IV unresectable penile squamous cell carcinoma presenting with anal bleeding and urethra obstruction who responded dramatically to combination therapy of durvalumab and cisplatin-based chemotherapy. The patient had HPV-positive penile squamous cell carcinoma, cT3N3M0, with concomitant anus squamous cell carcinoma. After 2 months of the combination treatment, almost all bulky inguinal lymph nodes shrank, and the main tumor of the anus and penis responded completely. A durable response was seen 16 months after initiating the combination therapy. This case report highlights the potential role of the combination of immunotherapy and chemotherapy in patients with advanced penile cancer. The promising results of this combination resulted in the conversion of unresectable disease to a potentially curable disease.

Abstract
Background The standard of care for unresectable, locally advanced non-small-cell lung cancer (LA-NSCLC) is chemoradiotherapy (CRT) followed by durvalumab, based on the PACIFIC study. Although multiple Japanese phase II studies have shown high efficacy and tolerability of CRT with cisplatin plus S-1 (SP), no prospective study using durvalumab after SP-based CRT has been reported. Objectives We conducted a multicenter phase II study of this approach, the interim analysis of which showed a high transition rate to durvalumab consolidation therapy. Here, we report the primary analysis results. Design In treatment-naïve LA-NSCLC, cisplatin (60 mg/m2, day 1) and S-1 (80-120 mg/body, days 1-14) were administered with two 4-week cycles with concurrent thoracic radiotherapy (60 Gy) followed by durvalumab (10 mg/kg) every 2 weeks for up to 1 year. Methods The primary endpoint was 1-year progression-free survival (PFS). The expected 1-year PFS and its lower limit of the 80% confidence interval (CI) were set as 63% and 47%, respectively, based on the results of TORG1018 study. Results In all, 59 patients were enrolled, with 51 (86.4%) proceeding to durvalumab. The objective response rate throughout the study was 72.9% (95% CI: 59.7-83.6%). After median follow-up of 21.9 months, neither median PFS nor OS was reached. The 1-year PFS was 72.5% (80% CI: 64.2-79.2%, 95% CI: 59.1-82.2%), while the 1-year overall survival was 91.5% (95% CI: 80.8-96.4%). No grade 5 adverse events were observed throughout the study. The most common adverse event during the consolidation phase was pneumonitis (any grade, 78.4%; grade ⩾3, 2.0%). Eventually, 52.5% of patients completed 1-year durvalumab consolidation therapy from CRT initiation. Conclusion This study of durvalumab after SP-based CRT met its primary endpoint and found a 1-year PFS of 73% from CRT initiation. This study provides the first prospective data on the prognosis and tolerability of durvalumab consolidation from the initiation of CRT.

Pre-Existing Interstitial Lung Abnormalities Are Independent Risk Factors for Interstitial Lung Disease during Durvalumab Treatment after Chemoradiotherapy in Patients with Locally Advanced Non-Small-Cell Lung Cancer. Cancers (Basel) 2022; 14:cancers14246236. [PMID: 36551721 PMCID: PMC9776853 DOI: 10.3390/cancers14246236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022] Open
Abstract
Introduction/Background: Chemoradiotherapy (CRT) followed by durvalumab, an immune checkpoint inhibitor, is the standard treatment for locally advanced non-small-cell lung cancer (NSCLC). Interstitial lung disease (ILD) is a life-threatening toxicity caused by these treatments; however, risk factors for the ILD have not yet been established. Interstitial lung abnormalities (ILAs) are computed tomography (CT) findings which manifest as minor interstitial shadows. We aimed to investigate whether ILAs could be risk factors for grade-two or higher ILD during durvalumab therapy. Patients and Methods: Patients with NSCLC who received durvalumab after CRT from July 2018 to June 2021 were retrospectively enrolled. We obtained patient characteristics, laboratory data, radiotherapeutic parameters, and chest CT findings before durvalumab therapy. Results: A total of 148 patients were enrolled. The prevalence of ILAs before durvalumab treatment was 37.8%. Among 148 patients, 63.5% developed ILD during durvalumab therapy. The proportion of patients with grade-two or higher ILD was 33.8%. The univariate logistic regression analysis revealed that older age, high dose-volume histogram parameters, and the presence of ILAs were significant risk factors for grade-two or higher ILD. The multivariate analysis showed that ILAs were independent risk factors for grade-two or higher ILD (odds ratio, 3.70; 95% confidence interval, 1.69−7.72; p < 0.001). Conclusions: We showed that pre-existing ILAs are risk factors for ILD during durvalumab treatment after CRT. We should pay attention to the development of grade-two or higher ILD during durvalumab treatment in patients with ILAs.

Abstract
RATIONALE Immune checkpoint inhibitors (ICIs) have been widely used in the treatment of various types of cancers worldwide, which is the most significant breakthrough in cancer therapy in recent years. Despite their excellent benefits in anti-tumor efficacy, a subset of patients will experience various autoimmune toxicities, termed as immune-related adverse events (irAEs), which can affect almost any organ systems, but related to the pulmonary and pancreatic islets simultaneously has rarely been reported and discussed. PATIENT CONCERNS In this report, we describe a rare case of a 65-year-old man patient with advanced small cell lung cancer (SCLC) who suffered general fatigue, dry cough, chest tightness, shortness of breath and polyuria-polydipsia syndrome after the eighth cycle treatment with programmed cell death ligand-1 (PD-L1) inhibitor durvalumab. DIAGNOSES According to the results of laboratory tests, chest computed tomography and multidisciplinary discussion, the patient was eventually diagnosed with ICI-related pneumonitis and autoimmune diabetes mellitus. INTERVENTIONS Multiple daily subcutaneous insulin injections, empirical anti-infection and immunosuppression treatment with corticosteroids were performed. OUTCOMES After the cessation of durvalumab and comprehensive treatment, the patient's respiratory condition was relieved significantly and his blood glucose was well controlled with insulin therapy. LESSONS With the widespread use of ICIs, there will be more patients developing these rare but severe irAEs in clinical practice, which should attract great attention of both clinicians and patients.

Abstract
BACKGROUND Malignant pleural mesothelioma (MPM) is a cancer with a high mortality rate and few therapeutic options. After platinum-pemetrexed combination, no further promising drug seems to be effective. Immune checkpoint inhibitors may have some activity in pretreated patients and no data are available in this population about durvalumab. MATERIALS AND METHODS DIADEM was a multicenter, open-label, single-arm, phase II trial aimed at evaluating the efficacy and safety of durvalumab. Patients with locally advanced/metastatic MPM who progressed after platinum-pemetrexed chemotherapy were enrolled to receive durvalumab (1500 mg, intravenously Q4W) for 12 months or until evidence of disease progression or unacceptable toxicity. The primary endpoint was the proportion of patients alive and free from progression at 16 weeks (PFS16wks) calculated from treatment initiation. Secondary endpoints were progression-free survival, overall survival, overall response rate, and safety. RESULTS Sixty-nine patients with a median age of 69 years (range 44-82 years) were enrolled; 62 patients (89.9%) had epithelioid histotype. As first-line treatment, all patients received platinum derivatives-pemetrexed combination (60.9% with carboplatin and 39.1% with cisplatin). As of March 2021, the median follow-up was 9.2 months (interquartile range 5.2-11.1 months). Six patients (8.7%) completed the 12-month treatment; 60 patients discontinued, of whom 42 for progressive disease, and 4 died. Seventeen patients (28.3%; 95% confidence interval 17.5% to 41.4%) were alive or free from progression at 16 weeks. Eleven patients (18.6%) had a grade 3 or 4 treatment-related adverse event (AE), and one (1.4%) had a grade ≥3 immune-related, treatment-related AE. There was one drug-related death. CONCLUSION Durvalumab alone in pretreated non-selected MPM did not reach a meaningful clinical activity, showing any new major safety issue signals.

Abstract
BACKGROUND The therapeutic efficacy of cytotoxic anticancer drugs has been reported to be enhanced after immune checkpoint inhibitors (ICI) in non-small cell lung cancer; however, it is unclear whether the same is applicable for small cell lung cancer (SCLC). We evaluated the efficacy of second-line amrubicin (AMR) following first-line platinum-based chemotherapy and ICI combination therapy (chemo-ICI) in SCLC. PATIENTS AND METHODS We retrospectively enrolled consecutive patients with SCLC treated with AMR as a second-line following chemo-ICI as first-line between July 2019 and April 2021 from 16 institutions throughout Japan. We investigated the therapeutic effectiveness, safety, and efficacy-enhancing variables of AMR. RESULTS Overall, 89 patients treated with AMR after first-line chemo-ICI were analyzed. The overall response rate (ORR) was 29.2% (95% confidence intervals [CI], 20.1-39.8) and median PFS (m PFS) was 2.99 months (95% CI, 2.27-3.65). Patients who relapsed more than 90 days after receiving first-line platinum combination therapy (sensitive relapse) exhibited greater ORR (58.3% vs. 24.7%, p = 0.035) and m PFS (5.03 vs. 2.56 months, p = 0.019) than patients who relapsed in <90 days (refractory relapse). Grade 3 or higher adverse events were mainly hematological toxicity. CONCLUSIONS Our study suggested that the therapeutic effect of AMR was not enhanced after ICI on SCLC. However, AMR may be effective in cases of sensitive relapse after chemo-ICI. There was no increase in severe toxicity associated with AMR after ICI.

Abstract
BACKGROUND Recently, the addition of antiprogrammed cell death-ligand 1 (PD-L1) monoclonal antibodies, including durvalumab and atezolizumab to platinum-based chemotherapy, has demonstrated clinical benefits in patients with untreated advanced small cell lung cancer (SCLC). However, these clinical trials comprised small populations of elderly patients with SCLC. Therefore, the safety of anti-PD-L1 immunotherapy plus platinum and etoposide in elderly patients remains unclear. METHODS This prospective, multicenter, single-arm study was designed to evaluate the safety and efficacy of durvalumab plus carboplatin and etoposide in untreated elderly patients (aged > 75) with extensive stage (ES) SCLC. A total of 40 patients were recruited. Patients received up to four cycles of durvalumab 1500 mg and carboplatin at a dose equivalent to an area under the curve of 5 on day 1, and etoposide 80 mg/m2 on days 1 to 3 every 3 weeks as induction treatment, followed by durvalumab maintenance treatment every 4 weeks. The primary endpoint was safety as measured by adverse events according to the Common Terminology Criteria for Adverse Events version 5.0, laboratory analyses, vital signs, and physical examination. Key secondary endpoints were objective response rate, median progression-free survival, 12-month overall survival rate, and the completion rate for four cycles of induction chemotherapy. DISCUSSION The present study was designed to evaluate the safety of durvalumab plus carboplatin and etoposide in elderly patients with ES-SCLC.

Abstract
Background Small-cell lung cancer (SCLC) accounts for 12–15% of lung cancers and has a limited prognosis, with approximately one-third of SCLC patients having a poor performance status (PS). Patients with extensive-stage (ES) SCLC and a poor PS have a poor prognosis. For this population, overall survival from carboplatin and etoposide treatment is 7–8 months, and treatment development is an unmet medical need. Recently, the combination of an anti-PD-L1 (a ligand for programmed cell death 1) antibody and platinum-based chemotherapy has become the standard of care for ES-SCLC patients with a good PS (PS 0–1). We hypothesized that the combination of the anti-PD-L1 antibody durvalumab with carboplatin and etoposide would be feasible and effective for such patients. Methods We initiated a multicenter phase II study of durvalumab combined with carboplatin and etoposide in previously untreated ES-SCLC patients with a poor PS (PS 2–3). Eligible patients will receive durvalumab plus carboplatin and etoposide every 3 to 4 weeks for up to 4 cycles, followed by durvalumab every 4 weeks until progression or unacceptable toxicity. The dosages of carboplatin and etoposide for the second and subsequent cycles will be adaptively determined based on the adverse events of the first cycle. A total of 56 patients (43 patients with a PS of 2 and 13 patients with a PS of 3) will be enrolled in this study, with a 24-month enrollment period and a 12-month follow-up. The primary endpoint is the tolerability of carboplatin and etoposide plus durvalumab in previously untreated ES-SCLC patients with a poor PS. The secondary endpoints are the 1-year survival rate, objective response rate, progression-free survival, overall survival, ratio of PS improvement, and safety. Discussion The results of this study are intended to establish the safety and efficacy of carboplatin and etoposide plus durvalumab in patients with ES-SCLC and a poor PS.

Abstract
Liver cancer is the third most common cause of cancer-related mortality worldwide, with over 780,000 deaths in 2018. About 90% of liver cancer cases are hepatocellular carcinoma (HCC), a prototype of inflammation-driven cancer, leading to a robust rationale for the exploration of immune therapy. Previously approved agents for first-line therapy, such as sorafenib, lenvatinib and bevacizumab combined with atezolizumab, have focused on angiogenesis. HIMALAYA was the first trial to demonstrate the benefit of dual immune checkpoint inhibitors, representing a new treatment option in this scenario.

Abstract
The aim of this study was to investigate the safety and efficacy of anti-programmed death ligand 1 (PD-L1) immunotherapy plus chemoradiotherapy for patients with limited-stage small cell lung cancer (LS-SCLC) in clinical practice. Patients with LS-SCLC treated with anti-PD-L1 (atezolizumab/durvalumab) plus chemoradiotherapy (CRT) as the initial treatment at three general hospitals between March 2020 and December 2021 were retrospectively analysed. 1:2 propensity score matching for controls that receive CRT only was performed. Clinical data (age, sex, history of cancer treatment, adverse events, etc.) were collected to evaluate toxicity, progression-free survival (PFS) and objective response rate (ORR). Researchers used univariate Chi-squared analyses to determine if anti-PD-L1 immunotherapy had a significant association with toxicity or ORR. Kaplan-Meier survival analysis, and the log-rank test were used to compare survival curves between the two groups. In the anti-PD-L1 plus CRT and CRT groups, 15 and 30 patients were analyzed; median follow-up was 16.39 months and 16.64 months, respectively. Incidence of toxicity between the two groups was similar and there were no new safety signals. Anti-PD-L1 immunotherapy significantly improved PFS (P = 0.02). The median PFS was not reached in the anti-PD-L1 plus CRT group versus 8.18 months [95% confidence interval (CI), 6.14-10.22 months] in the CRT group. The ORR were 93.33% and 76.67%, respectively (P = 0.34). This study supports adding anti-PD-L1 immunotherapy (atezolizumab/durvalumab) to CRT as an initial treatment option in patients with LS-SCLC for its favorable safety profile and efficacy.

Abstract
Systemic treatments have traditionally reported limited efficacy for biliary tract cancer (BTC), and although targeted therapies and immune checkpoint inhibitors have been found to play an increasingly important role in treatment, several questions remain unanswered, including the identification of biomarkers of response. The tumor microenvironment (TME) has recently attracted the attention of the BTC medical community, and is currently being studied due to its potential role in modulating response and resistance to systemic therapies, including immunotherapy. In this perspective article, we discuss available evidence regarding the interplay between TME, IDH inhibitors, and immunotherapy, providing rationale for the design of future clinical trials.

Cost-effectiveness analysis of the new oncological drug durvalumab in Italian patients with stage III non-small cell lung cancer. Thorac Cancer 2022; 13:2692-2698. [PMID: 35971638 PMCID: PMC9527163 DOI: 10.1111/1759-7714.14531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 05/19/2022] [Accepted: 05/23/2022] [Indexed: 12/03/2022] Open
Abstract
Background The monoclonal antibody durvalumab, an immune‐checkpoint inhibitor (ICI) antiprogrammed death ligand 1 (PD‐L1), is available for unresectable stage III NSCLC patients as consolidation therapy following induction chemoradiotherapy, with very promising overall survival (OS) and progression‐free survial (PFS) results in registration trials. The purpose of this study was to provide policymakers with an estimate of the cost‐effectiveness of durvalumab in the treatment of non‐small cell lung cancer (NSCLC). Methods The study developed a Markov model covering a 5‐year period to compare costs and outcomes of treating PD‐L1 positive patients with or without durvalumab. We conducted a series of sensitivity analyses (Tornado analysis and Monte Carlo simulation) by varying some parameters to assess the robustness of our model and identify the parameters with the greatest impact on cost‐effectiveness. Results Prior to the release of durvalumab, the management of NSCLC over a 5‐year period cost €33 317 per patient, with an average life expectancy of 2.01 years. After the introduction of the drug, this increased to €37 317 per patient, with an average life expectancy of 2.13 years. Treatment with durvalumab led to an incremental cost‐effectiveness ratio (ICER) of €35 526 per year. OS is the variable that contributes the most to the variability of the ICER. Conclusions The study observed that durvalumab is a cost‐effective treatment option for patients with unresectable stage III NSCLC.

Neoadjuvant durvalumab improves survival in early triple-negative breast cancer independent of pathological complete response. Ann Oncol 2022; 33:1149-1158. [PMID: 35961599 DOI: 10.1016/j.annonc.2022.07.1940] [Citation(s) in RCA: 69] [Impact Index Per Article: 34.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 06/22/2022] [Accepted: 07/27/2022] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Addition of immune checkpoint inhibitors (CPI) to neoadjuvant chemotherapy (NACT) is a promising strategy in early breast cancer, but the optimal duration of therapy is currently unknown. In the GeparNuevo (NCT02685059) trial, addition of durvalumab to NACT as previously reported led to a moderate increase in pCR rate by absolute 9% (p=0.287). PATIENTS AND METHODS Durvalumab or placebo 1.5g/placebo q4 weeks plus nab-paclitaxel 125mg/m2 weekly for 12 weeks, followed by 4 cycles durvalumab/placebo plus epirubicin/cyclophosphamide (EC) q2 weeks was given to cT1b-cT4a-d TNBC patients. Durvalumab was not continued after surgery. Primary objective was pathological complete response (pCR). Secondary endpoints included invasive disease-free survival (iDFS), distant disease-free survival (DDFS) and overall survival (OS). RESULTS 174 patients were randomised between June 2016 and October 2017. After a median follow-up of 43.7 months, 34 events had occurred. Despite a non-significant increase in the pCR rate, significant differences were observed for 3-year iDFS, DDFS and OS: iDFS was 85.6% with durvalumab vs 77.2% with placebo (HR 0.48, 95%CI 0.24-0.97, stratified log-rank p=0.036); DDFS 91.7% vs 78.4% (HR 0.31, 95%CI 0.13-0.74, p=0.005); OS 95.2% vs 83.5% (HR 0.24, 95%CI 0.08-0.72, p=0.006). pCR patients had 3-year iDFS of 95.5% with durvalumab and 86.1% without (HR 0.22, 95% CI 0.05-1.06). In non-pCR cohort 3-year iDFS was 76.3% vs 69.7% (HR 0.67, 95% CI 0.29-1.54). Multivariable analysis confirmed durvalumab effect independent of the pCR effect. No new safety signals occurred. CONCLUSION Durvalumab added to NACT in TNBC significantly improved survival despite a modest pCR increase and no adjuvant component of durvalumab. Additional studies are needed to clarify the optimal duration and sequence of CPIs in the treatment of early TNBC.

Abstract
Glioblastoma (GBM) is the most common primary brain tumor. Due to high resistance to treatment, local invasion, and a high risk of recurrence, GBM patient prognoses are often dismal, with median survival around 15 months. The current standard of care is threefold: surgery, radiation therapy, and chemotherapy with temozolomide (TMZ). However, patient survival has only marginally improved. Radioimmunotherapy (RIT) is a fourth modality under clinical trials and aims at combining immunotherapeutic agents with radiotherapy. Here, we develop in vitro assays for the rapid evaluation of RIT strategies. Using a standard cell irradiator and an Electric Cell Impedance Sensor, we quantify cell migration following the combination of radiotherapy and chemotherapy with TMZ and RIT with durvalumab, a PD-L1 immune checkpoint inhibitor. We measure cell survival using a cloud-based clonogenic assay. Irradiated T98G and U87 GBM cells migrate significantly (p < 0.05) more than untreated cells in the first 20−40 h post-treatment. Addition of TMZ increases migration rates for T98G at 20 Gy (p < 0.01). Neither TMZ nor durvalumab significantly change cell survival in 21 days post-treatment. Interestingly, durvalumab abolishes the enhanced migration effect, indicating possible potency against local invasion. These results provide parameters for the rapid supplementary evaluation of RIT against brain tumors.

Abstract
RATIONALE Despite clinical-proven benefits of immune checkpoint inhibitors (ICIs) on advanced lung cancer, rare but life-threatening immune-related adverse events (irAEs) have been reported. Pancreatitis is a rare irAE that can occur with any ICI. PATIENT CONCERNS A 53-year-old man with locally advanced non-small cell lung carcinoma was treated with radiochemotherapy and then durvalumab (anti-programmed cell death ligand 1 therapy). Twelve weeks after the beginning of ICI, he reported abdominal pain and anorexia. Blood test showed high level of lipase. Abdominal computed tomography revealed a swollen pancreas. These findings were confirmed by magnetic resonance cholangiopancreatography and biliopancreatic endoscopic ultrasonography. DIAGNOSES Grade IV immune-related pancreatitis. INTERVENTIONS The patient was treated with corticosteroid therapy, resulting in clinical, radiological, and biological improvement. OUTCOMES During the first month, corticosteroid therapy could not be decreased under 1 mg/kg/d because of symptoms recurrence and lipasemia rerising. Four months after this episode, the patient died from acute ischemia of the lower limbs while he was on <20 mg/d of corticosteroid. LESSONS To the best of our knowledge, immune-related pancreatitis has been reported only with anti-programmed cell death 1 or anti-cytotoxic T lymphocyte antigen 4 therapies but never with anti-programmed cell death ligand 1 therapy. It is important to report such rare cases to improve diagnosis and management of irAEs.

Abstract
BACKGROUND /PURPOSE Higher estimated radiation doses to immune cells (EDIC) have correlated with worse overall survival (OS) in patients with locally-advanced non-small cell lung cancer (NSCLC) prior to the PACIFIC trial, which established consolidative durvalumab as standard-of-care. Here, we examine the prognostic impact of EDIC in the durvalumab era. MATERIALS/METHODS This single-institution, multi-center study included patients with unresectable stage II/III NSCLC treated with chemoradiation followed by durvalumab. Associations between EDIC [analyzed continuously and categorically (≤6 Gy vs. >6 Gy)] and OS, progression-free survival (PFS), and locoregional control (LRC) were evaluated by Kaplan-Meier and Cox proportional methods. RESULTS 100 patients were included with median follow-up of 23.7 months. The EDIC >6 Gy group had a significantly greater percentage of stage IIIB/IIIC disease (76.0% vs. 32.6%; p<0.001) and larger tumor volumes (170cc vs. 42cc; p<0.001). There were no differences in early durvalumab discontinuation from toxicity (24.1% vs. 15.2%; p=0.27). Median OS was shorter among the EDIC >6 Gy group (29.6 months vs. not reached; p<0.001). On multivariate analysis, EDIC >6 Gy correlated with worse OS (HR: 4.15, 95%CI: 1.52-11.33; p=0.006), PFS (HR: 3.79; 95%CI: 1.80-8.0; p<0.001), and LRC (HR: 2.66, 95%CI: 1.15-6.18; p=0.023). Analyzed as a continuous variable, higher EDIC was associated with worse OS (HR: 1.34; 95%CI: 1.16-1.57; p<0.001), PFS (HR: 1.52; 95%CI: 1.29-1.79; p<0.001), and LRC (HR: 1.34, 95%CI: 1.13-1.60; p=0.007). CONCLUSIONS In the immunotherapy era, EDIC is an independent predictor of OS and disease control in locally advanced NSCLC, warranting investigation into techniques to reduce dose to the immune compartment.

Durvalumab as monotherapy and in combination therapy in patients with lymphoma or chronic lymphocytic leukemia: The FUSION NHL 001 trial. Cancer Rep (Hoboken) 2022; 6:e1662.

Abstract
BACKGROUND Studies suggest that immune checkpoint inhibitors may represent a promising strategy for boosting immune responses and improving the antitumor activity of standard therapies in patients with relapsed/refractory hematologic malignancies. AIMS Phase 1/2 FUSION NHL 001 was designed to determine the safety and efficacy of durvalumab, an anti-programmed death ligand 1 (PD-L1) antibody, combined with standard-of-care therapies for lymphoma or chronic lymphocytic leukemia (CLL). METHODS AND RESULTS The primary endpoints were to determine the recommended phase 2 dose of the drugs used in combination with durvalumab (durvalumab was administered at the previously recommended dose of 1500 mg every 4 weeks) and to assess safety and tolerability. Patients were enrolled into one of four arms: durvalumab monotherapy (Arm D) or durvalumab in combination with lenalidomide ± rituximab (Arm A), ibrutinib (Arm B), or rituximab ± bendamustine (Arm C). A total of 106 patients with relapsed/refractory lymphoma were enrolled. All but two patients experienced at least one treatment-emergent adverse event (TEAE); those not experiencing a TEAE were in Arm C (diffuse large B-cell lymphoma [DLBCL]) and Arm D (DLBCL during the durvalumab monotherapy treatment period). No new safety signals were identified, and TEAEs were consistent with the respective safety profiles for each study treatment. Across the study, patients with follicular lymphoma (FL; n = 23) had an overall response rate (ORR) of 59%; ORR among DLBCL patients (n = 37) was 18%. Exploratory biomarker analysis showed that response to durvalumab monotherapy or combination therapy was associated with higher interferon-γ signature scores in patients with FL (p = .02). CONCLUSION Durvalumab as monotherapy or in combination is tolerable but requires close monitoring. The high rate of TEAEs during this study may reflect on the difficulty in combining durvalumab with full doses of other agents. Durvalumab alone or in combination appeared to add limited benefit to therapy.

Abstract
The pivotal PACIFIC trial defined durvalumab consolidation as the new standard of care in patients with stage III non-small-cell lung cancer treated with definitive radiochemotherapy. The authors characterized the durvalumab effect after induction chemotherapy according to the ESPATUE trial and definitive radiochemotherapy. All consecutive patients with stage III non-small-cell lung cancer receiving definitive radiochemotherapy between January 2017 and February 2020 were included. Primary end points were progression-free survival and overall survival. Altogether, 160 patients (75 PD-L1-positive, 62 PD-L1-negative, 23 unknown) received definitive radiochemotherapy, 146 (91%) of whom received prior induction chemotherapy. Durvalumab consolidation showed high effectiveness overall and in the good-risk group according to the PACIFIC trial (log-rank test: p < 0.005). Hazard ratios for progression-free survival and overall survival were at the lower limits of those in the PACIFIC trial. These results were robust to adjustment for potential confounders by propensity score weighting. Eastern Cooperative Oncology Group (ECOG) performance status was the most important pretreatment prognostic factor.

Durvalumab after Sequential High Dose Chemoradiotherapy versus Standard of Care (SoC) for Stage III NSCLC: A Bi-Centric Trospective Comparison Focusing on Pulmonary Toxicity. Cancers (Basel) 2022; 14:3226. [PMID: 35804997 PMCID: PMC9265119 DOI: 10.3390/cancers14133226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 06/27/2022] [Accepted: 06/27/2022] [Indexed: 01/09/2023] Open
Abstract
Introduction: The standard of care (SoC) for unresectable stage III non-small-cell lung cancer (NSCLC) is durvalumab maintenance therapy after concurrent chemoradiation in patients with PD-L1 > 1%. However, the concurrent approach is only amenable for about one-third of patients due to co-morbidities. Although sequential regimens are usually not regarded as curative, these schedules applied in a dose-escalated manner may be similarly radical as SoC. As combining high-dose radiation and durvalumab remains a question of debate this retrospective bi-center study aims to evaluate pulmonary toxicity after high-dose chemoradiotherapy beyond 70 Gy compared to SoC. Patients and Methods: Patients with NSCLC stage III received durvalumab after either sequential high-dose chemoradiation or concomitant SoC. Chemotherapy consisted of platinum combined with either pemetrexed, taxotere, vinorelbine, or gemcitabine. The primary endpoint was short-term pulmonary toxicity occurring within six months after the end of radiotherapy (RT). Results: A total of 78 patients were eligible for this analysis. 18F-FDG-PET-CT, cranial MRT, and histological/cytological verification were mandatory in the diagnostic work-up. The high-dose and SoC group included 42/78 (53.8%) and 36/78 (46.2%) patients, respectively, which were matched according to baseline clinical variables. While the interval between the end of RT and the start of durvalumab was equal in both groups (p = 0.841), more courses were administered in the high-dose cohort (p = 0.031). Pulmonary toxicity was similar in both groups (p = 0.599), whereas intrathoracic disease control was better in the high-dose group (local control p = 0.081, regional control p = 0.184). Conclusion: The data of this hypothesis-generating study suggest that sequential high-dose chemoradiation followed by durvalumab might be similar to SoC in terms of pulmonary toxicity and potentially more effective with respect to intra-thoracic disease control. Larger trials with a prospective design are warranted to validate these results.
