Rojas-Roque C, Silvestrini C, Argento F, Sugg D, Augustovski F, Coelli J, Espinola N. Budget Impact Analysis of Olaparib in Combination with Bevacizumab for Maintenance Therapy for Ovarian Cancer in Argentina. PHARMACOECONOMICS - OPEN 2024; 8:585-598. [PMID: 38831188 PMCID: PMC11252110 DOI: 10.1007/s41669-024-00495-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 05/05/2024] [Indexed: 06/05/2024]
Abstract
OBJECTIVES To perform a budget impact analysis (BIA) of introducing olaparib as maintenance therapy in women who have BRCA mutations (BRCAm) with platinum-sensitive recurrent ovarian cancer (PSROC) in combination with bevacizumab in Argentina. METHODS A BIA model was used to analyse over a 5-year time horizon the change in the health system's budget following the adoption of olaparib as maintenance therapy in BRCAm patients with PSROC. The BIA for each year was estimated by comparing the cost difference between the current scenario (treatment with bevacizumab) and the new scenario (the addition of olaparib) for a third-party payer. The BIA is estimated at the national health system level, and by healthcare sectors in Argentina (public sector, social security and private sector). International and national epidemiological data were used to determine the target patient population. Clinical efficacy, safety outcomes and duration of treatments were obtained from the pivotal clinical study report. Relevant direct medical costs were obtained from public data in Argentina and expert consultation. All the costs are reported in US dollars as of October 2022 ($1 = 152.59 Argentine pesos). A scenario analysis assessed the full coverage of the homologous recombination deficiency (HRD) test in Argentina. In addition, one-way sensitivity analysis was conducted to evaluate the model robustness. RESULTS For a third-party payer with a cohort of 1,000,000 women covered, the estimated target population was 2 individuals in year 1 and 6 individuals in year 5. The incorporation of olaparib, with a wholesale price per pack of $3176.32, was associated with a weighted average of the budget impact per member per month (PMPM) of $0.062 for the national health system, being above the estimated health system budget impact threshold ($0.0153). By healthcare sector, the results of budget impact PMPM for year 5 ranged between $0.08 (public sector) and $0.114 (private sector). For all perspectives, the variables that most influenced the budget impact was the incidence of ovarian cancer, the drug acquisition cost and the treatment duration. CONCLUSIONS The introduction of olaparib for the treatment of BRCAm women with PSROC has a high budget impact for all three health systems in Argentina.

Systematic analysis of off-label and off-guideline cancer therapy usage in a real-world cohort of 165,912 US patients. Cell Rep Med 2024; 5:101444. [PMID: 38428426 PMCID: PMC10983036 DOI: 10.1016/j.xcrm.2024.101444] [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: 11/22/2022] [Revised: 12/28/2023] [Accepted: 02/06/2024] [Indexed: 03/03/2024]
Abstract
Patients with cancer may be given treatments that are not officially approved (off-label) or recommended by guidelines (off-guideline). Here we present a data science framework to systematically characterize off-label and off-guideline usages using real-world data from de-identified electronic health records (EHR). We analyze treatment patterns in 165,912 US patients with 14 common cancer types. We find that 18.6% and 4.4% of patients have received at least one line of off-label and off-guideline cancer drugs, respectively. Patients with worse performance status, in later lines, or treated at academic hospitals are significantly more likely to receive off-label and off-guideline drugs. To quantify how predictable off-guideline usage is, we developed machine learning models to predict which drug a patient is likely to receive based on their clinical characteristics and previous treatments. Finally, we demonstrate that our systematic analyses generate hypotheses about patients' response to treatments.

Abstract
OBJECTIVES The aim of this study was to provide real-world efficacy and safety data on niraparib maintenance treatment in patients with non-germline (gBRCA)1/2 mutated platinum-sensitive recurrent ovarian cancer. METHODS This retrospective multi-center cohort study included 94 platinum-sensitive recurrent ovarian cancer patients without known gBRCA1/2 mutation treated in an individual patient access program in Norway. The primary outcome was time from start of niraparib treatment to first subsequent treatment. Secondary endpoints included progression-free survival, safety, and tolerability. RESULTS After median follow-up of 13.4 months (95% confidence interval (CI) 10.0 to 16.8), 68.1% had progressed and 22.3% had died. Of the entire cohort, 61.7% had commenced a new line of treatment, and 24.5% were still receiving niraparib. The median duration of niraparib treatment was 5.0 months (range 0.4 to 27.3), and the median time to first subsequent treatment was 10.7 months (95% CI 8.4 to 13.0). Patients with elevated CA125 prior to start of niraparib had shorter time to first subsequent treatment (7.3 months, 95% CI 4.2 to 10.3) than patients with normalized CA125 (12.2 months, 95% CI 10.9 to 13.7 (p=0.002). Patients who started on individual dose based on weight and platelet counts had fewer dose reductions (p<0.001) and interruptions (p=0.02). CONCLUSION In a real-world setting, niraparib maintenance treatment in patients with non-gBRCA1/2 mutated recurrent platinum-sensitive ovarian cancer showed effectiveness comparable with published phase III studies and acceptable safety. Individualized dosing is essential to minimize adverse events. CA125 levels at start of niraparib treatment may help to estimate the individual prognosis.

Abstract
BACKGROUND Poly (ADP-ribose) polymerase (PARP) inhibitors are a new maintenance therapy option for patients with ovarian cancer (OC). OBJECTIVE To evaluate the efficacy and influencing factors of the novel PARP inhibitor niraparib for maintenance treatment of Chinese patients with advanced OC. PATIENTS AND METHODS In this retrospective multicenter real-world study patients with advanced OC from 15 hospitals throughout China were enrolled. The primary endpoint was progression-free survival (PFS) and the secondary endpoints included the time to treatment discontinuation and safety. Least Absolute Shrinkage and Selection Operator (LASSO) regression was used to identify possible risk factors for PFS, after which a prediction model was established to evaluate the likelihood of achieving an 18-month PFS. The relationship between the dose of niraparib and PFS was also evaluated. RESULTS The PFS rates of 199 patients at 6, 12, 18, 24, and 30 months were 87.4%, 75.9%, 63.6%, 56.1%, and 51.8%, respectively. LASSO regression model revealed that only age < 65 years (P = 0.011), BRCA mutations (P < 0.001), and R0 status after cytoreductive surgery (P = 0.01) were significant factors associated with prolonged PFS times. Based on the LASSO logistic regression analysis, a clinical prediction formula was developed: - 2.412 + 1.396Age≥65yr + 2.374BRCAwt + 1.387R1 + 0.793Interval≥12w + 0.178BMI>24kg/m2 which yielded a cut-off value of 0.091, an area under the curve (AUC) of 0.839 (0.763-0.916), a sensitivity of 94.3%, and an accuracy of 78.5%. A nomogram was then built to visualize the results. The major treatment-emergent adverse events of ≥ grade 3 included a platelet count decrease (19.1%), white blood cell count decrease (15.1%), neutrophil count decrease (13.1%), and anemia (18.6%). The 18-month PFS rates in patients treated with 200 mg niraparib were somewhat higher than in patients treated with 100 mg after 3-months of therapy. CONCLUSIONS For Chinese OC patients, niraparib, particularly at a 200 mg individual starting dose, was an effective therapy with easily manageable safety.

Abstract
Introduction: Over the last few years, targeted therapy has become the mainstay maintenance treatment of patients with ovarian cancer including patients with BRCA1/BRCA2 mutations. Poly ADP ribose polymerase inhibitors (PARPi) are effective in the treatment of patients who are in complete or partial remission. PARPi are known to cause hematological adverse events (AEs), but have not been compared directly to each other. Objective: Primary objective was to compare the incidence of hematological and non-hematological AEs associated with the use of PARPi. Methods: This was a single institution, retrospective study evaluating patients who were treated with PARPi for ovarian cancer from January 2017 to October 2020. Patients were stratified according to which PARP inhibitor they received. Results: Ninety-two patients were included in final analysis. Thirty-one (33.7%) patients received niraparib and 61 (66.3%) patients received olaparib. Median age of patients were 64.3 (range, 33.8 to 92.3) years, 66 (71.7%) were white, and 84 (91.3%) had an ECOG PS of 0/1. Patients in the niraparib group experienced a higher rate of hematologic AEs, with 11 (35.5%), 20 (64.5%), and 18 (58.1%) experiencing neutropenia, anemia, and thrombocytopenia, respectively. Eight (13.1%), 24 (39.3%), and 16 (26.2%) patients in the olaparib group experienced neutropenia, anemia, and thrombocytopenia, respectively. Conclusion: This single institution retrospective study outlines the hematological toxicities observed between two PARPi. Our results suggested that niraparib tended to be associated with a higher risk for hematologic toxicities than olaparib. Anemia was the most common hematologic toxicity which was consistent with what has been widely documented in the literature.

Abstract
Olaparib showed good efficacy and tolerability in the maintenance treatment of patients with initial therapy or high-grade serous recurrent ovarian cancer patients. This study aimed to analyze adverse events (AEs) of patients taking Olaparib and the quality of life (QoL) with Olaparib in 1 center of China. The study included 98 patients who received Olaparib and 210 patients without Olaparib from July 2018 to October 2021 for high-grade serous ovarian cancer in the Gynecology Oncology Department of Jiangsu Provincial Hospital. Information of clinicopathologic characteristics was collected from medical records. Then, we used the QLQ-C30 and Quality of Life Ovarian Cancer 28 Questionnaire (QLQ-OV28) to determine the QoL of 98 patients with and 210 patients without Olaparib. Among all 98 patients with Olaparib, 66 patients in first-line and 32 patients in more than second-line treatment. Regarding the best objective response with Olaparib maintenance in 78 patients with partial remission from most recent chemotherapy, 3 (3.84%) patients showed complete response (CR) and 6 (7.69%) showed as partial response (PR), whereas stable disease was observed in 42 patients (53.84%) and 27 patients (34.6%) showed as progression disease. AEs of Grade 3 and more were: anemia in 16 patients (16.32%), neutropenia in 20 patients (20.40%), thrombocytopenia in 4 patients (4.08%), and headache in 4 patients (4.08%). Dose reduction and drug discontinuation accounted for 73.40% and 20.40%, respectively. Olaparib as maintenance therapy increased QoL on all functioning domains and several symptom domains. Consistent with previous clinical trials, Olaparib maintenance therapy was proved safe and effective. Most patients may experience Grade 1 and 2 AEs. Olaparib maintenance therapy can increase QoL in several domains.

Abstract
BACKGROUND Olaparib is given in a fixed dose of twice-daily 300 mg in patients who are diagnosed with ovarian cancer, breast cancer, prostate cancer or pancreas cancer and has a high interpatient variability in pharmacokinetic exposure. The objective of this study was to investigate whether pharmacokinetic exposure of olaparib is related to efficacy and safety in a real-life patient' cohort. METHODS A longitudinal observational study was conducted in patients who received olaparib for metastatic ovarian cancer of whom pharmacokinetic samples were collected. A Kaplan-Meier analyses was used to explore the relationship between olaparib exposure, measured as (calculated) minimum plasma concentrations (Cmin), and efficacy, Univariate and multivariate cox-regression analyses were performed. Also, the Cmin of patients who experienced toxicity was compared with patients who did not experience any toxicity. RESULTS Thirty-five patients were included in the exposure-efficacy analyses, with a median olaparib Cmin of 1514 ng/mL. There was no statistical significant difference in PFS of patients below and above the median Cmin concentration of olaparib, with a hazard ratio of 1.06 (95% confidence interval: 0.46-2.45, p = 0.9)). For seven patients pharmacokinetic samples were available before toxicity occurred, these patients had a higher Cmin of olaparib in comparison with patients who had not experienced any toxicity (n = 33), but it was not statistically significant (p = 0.069). CONCLUSIONS Our study shows that exposure of olaparib is not related to PFS. This suggests that the approved dose of olaparib yields sufficient target inhibition in the majority of patients.

Determinants of the Empiric Use of Antibiotics by General Practitioners in South Africa: Observational, Analytic, Cross-Sectional Study. Antibiotics (Basel) 2022; 11:antibiotics11101423. [PMID: 36290081 PMCID: PMC9598257 DOI: 10.3390/antibiotics11101423] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 10/11/2022] [Accepted: 10/12/2022] [Indexed: 11/30/2022] Open
Abstract
The overuse of antibiotics is the main driver of antimicrobial resistance (AMR). However, there has been limited surveillance data on AMR and antibiotic prescribing at a primary healthcare level in South Africa. An observational, analytic, cross-sectional study was undertaken to assess key factors associated with empiric antibiotic prescribing among private sector general practitioners (GPs) in the eThekwini district in South Africa, particularly for patients with acute respiratory infections (ARIs). A semi-structured web-based questionnaire was used between November 2020−March 2021. One hundred and sixteen (55.5%) responding GPs prescribed antibiotics empirically for patients with ARIs more than 70% of the time, primarily for symptom relief and the prevention of complications. GPs between the ages of 35−44 years (OR: 3.38; 95%CI: 1.15−9.88), >55 years (OR: 4.75; 95% CI 1.08−21) and in practice < 15 years (OR: 2.20; 95%CI: 1.08−4.51) were significantly more likely to prescribe antibiotics empirically. Three factors—workload/time pressures; diagnostic uncertainty, and the use of a formulary, were significantly associated with empiric prescribing. GPs with more experience and working alone were slightly less likely to prescribe antibiotics empirically. These findings indicate that a combination of environmental factors are important underlying contributors to the development of AMR. As a result, guide appropriate interventions using a health system approach, which includes pertinent prescribing indicators and targets.

Challenges and Opportunities With Routinely Collected Data on the Utilization of Cancer Medicines. Perspectives From Health Authority Personnel Across 18 European Countries. Front Pharmacol 2022; 13:873556. [PMID: 35865969 PMCID: PMC9295616 DOI: 10.3389/fphar.2022.873556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/18/2022] [Indexed: 11/21/2022] Open
Abstract
Background: Rising expenditure for new cancer medicines is accelerating concerns that their costs will become unsustainable for universal healthcare access. Moreover, early market access of new oncology medicines lacking appropriate clinical evaluation generates uncertainty over their cost-effectiveness and increases expenditure for unknown health gain. Patient-level data can complement clinical trials and generate better evidence on the effectiveness, safety and outcomes of these new medicines in routine care. This can support policy decisions including funding. Consequently, there is a need for improving datasets for establishing real-world outcomes of newly launched oncology medicines. Aim: To outline the types of available datasets for collecting patient-level data for oncology among different European countries. Additionally, to highlight concerns regarding the use and availability of such data from a health authority perspective as well as possibilities for cross-national collaboration to improve data collection and inform decision-making. Methods: A mixed methods approach was undertaken through a cross-sectional questionnaire followed-up by a focus group discussion. Participants were selected by purposive sampling to represent stakeholders across different European countries and healthcare settings. Descriptive statistics were used to analyze quantifiable questions, whilst content analysis was employed for open-ended questions. Results: 25 respondents across 18 European countries provided their insights on the types of datasets collecting oncology data, including hospital records, cancer, prescription and medicine registers. The most available is expenditure data whilst data concerning effectiveness, safety and outcomes is less available, and there are concerns with data validity. A major constraint to data collection is the lack of comprehensive registries and limited data on effectiveness, safety and outcomes of new medicines. Data ownership limits data accessibility as well as possibilities for linkage, and data collection is time-consuming, necessitating dedicated staff and better systems to facilitate the process. Cross-national collaboration is challenging but the engagement of multiple stakeholders is a key step to reach common goals through research. Conclusion: This study acts as a starting point for future research on patient-level databases for oncology across Europe. Future recommendations will require continued engagement in research, building on current initiatives and involving multiple stakeholders to establish guidelines and commitments for transparency and data sharing.

Abstract
OBJECTIVES While there are good Budget Impact Analysis (BIA) guidelines, studies still register potential bias. To do this, we compared the results between theoretical and real-world evidence (RWE) expenditures for medicines for Hepatitis C: boceprevir (BOC) and telaprevir (TVR). While both are not currently recommended in treatment guidelines following recent developments, this is an emblematic case because for 4 years these medicines consumed considerable resources. METHODS Theoretical results and RWE expenditures were compared regarding the incorporation of BOC and TVR in 2013-2014 into the Brazilian Public Health System. Theoretical values were extracted from Commission for Technology Incorporation Report and RWE expenditures were extracted from the administrative data records using deterministic-probabilistic linkage. RESULTS The estimated number of patients treated (BOC+TVR) was 13,012 versus 7,641 (real). The estimated purchase price for BOC was US$6.20 versus US$11.07 (real) and for TVR was US$42.21 versus US$84.09 (average/real). The estimated budget impact was US$285.16 million versus US$128.58 million (real). CONCLUSION This study demonstrates appreciable divergence (US$156.58 million) between the theoretical budget impact and RWE expenditures due to underestimated purchase prices and overestimated populations. The greater the degree of accuracy the more reliable and usable BIAs become for decision-making.

Abstract
OBJECTIVE The first Poly (adenosine diphosphate [ADP]-ribose) polymerase inhibitor, olaparib, was approved by Taiwan Food and Drug Administration in June 2018, which was available under a compassionate use program since 2015. This study aims to report the early experience of the effectiveness and adverse effects of olaparib in recurrent ovarian cancer patients in Taiwan. MATERIALS AND METHODS This retrospective study enrolled patients with recurrent epithelial ovarian and peritoneal cancer who received olaparib as maintenance therapy or salvage therapy between December, 2015 and October, 2019. We observed response rates in the salvage therapy group, and progression-free interval (PFI) in both groups. RESULTS A total of 20 patients (10 in maintenance and 10 in salvage groups) were enrolled. BRCA status was checked in 18 patients by blood or tumor samples, and 83.3% were mutated (n = 15), including pathological/probable pathological variants in BRCA1 (n = 11), BRCA2 (n = 2), or both BRCA1/BRCA2 (n = 2). In the salvage group, there were two partial responses and two stable diseases, adding up to a clinical benefit rate at 40%. In the maintenance group, median PFI was 20.1 months (range, 1.0-33.1). The median PFI of those with chemotherapy-free interval >12 months was not reached, which was significantly better than those ≤12 months, with median PFI 3.1 months (p = 0.022). The most common grade 3/4 adverse effects in patient with olaparib as monotherapy were neutropenia (30.8%) and fatigue (7.7%). Anemia of grade 1/2 was noted in 76.9%. CONCLUSION This real-world experience of olaparib for recurrent ovarian cancer in Taiwan showed efficacy and safety similar to the results of previous clinical trial.

Abstract
INTRODUCTION Poly-adenosine diphosphate ribose polymerase inhibitors (PARPi) have become a cornerstone of therapy in the management ovarian cancer and other cancers. PARPi are associated with significant toxicities and management strategies are primarily founded on clinical trial experience. This study aimed to provide an evaluation of patients receiving PARPi therapy within an academic health-system. METHODS A retrospective, observational study of adult patients with gynecologic malignancy was conducted at the University of Pennsylvania Health System. Data was collected on patients prescribed a PARPi between December 2014 and October 2019. The primary endpoint was the status of PARPi therapy at the end of the study period. Key secondary endpoints included toxicity management strategies, time to discontinuation due to toxicity, progression free survival (PFS), and overall survival (OS). RESULTS Of the 85 patients included, 45 (53%) received olaparib, 24 (28%) niraparib, and 16 (19%) rucaparib. Twenty-nine patients (34%) continued on therapy, 15 (18%) discontinued due to toxicity, and 41 (48%) discontinued due to progression. Fifty-one percent of patients required a dose reduction due to toxicities. The median time to discontinuation due to toxicity was 69 days (9-353). Median PFS was 181 days (9-365) and median OS was 338 days (9-365). CONCLUSION PARPi therapy is associated with numerous toxicities that are best managed through a multi-modal approach. Importantly, about half the patients in the current study required a dose reduction. Overall, this observational study outlines the incidence of PARPi toxicities and reviews potential management strategies, further guiding practitioners in an area with limited real-world experience.

Abstract
Analysis of circulating tumor cells (CTCs) collected from patient's blood offers a broad range of opportunities in the field of precision oncology. With new advances in profiling technology, it is now possible to demonstrate an association between the molecular profiles of CTCs and tumor response to therapy. In this Review, we discuss mechanisms of tumor resistance to therapy and their link to phenotypic and genotypic properties of CTCs. We summarize key technologies used to isolate and analyze CTCs and discuss recent clinical studies that examined CTCs for genomic and proteomic predictors of responsiveness to therapy. We also point out current limitations that still hamper the implementation of CTCs into clinical practice. We finally reflect on how these shortcomings can be addressed with the likely contribution of multiparametric approaches and advanced data analytics.

Abstract
Objectives: Budget Impact Analyses (BIA) of medicines helps managers in promoting health systems' sustainability when assessing the role and value of new medicines. However, it is not clear whether BIAs typically underestimate or overestimate the impact on real-world budgets. This retroactive analysis seeks to compare estimated values obtained by a BIA and Real-World Evidence (RWE) to guide discussions.Methods: The estimated values were obtained through a BIA concerning the incorporation of adalimumab for the treatment of Rheumatoid Arthritis into the Brazilian Unified Health System (SUS) carried out retroactively and per international guidelines. RWE data was extracted from SUS computerized systems. We subsequently compared the number of treatments, costs, and Incremental Budget Impact (IBI).Results - The total number of treatments was underestimated by 10% (6,243) and the total expenditure was overestimated by 463% (US$ 4.7 billion). In five years, the total difference between the estimated values and real IBI reached US$ 1.1 billion. A current expenditure of US$ 1.0 was observed for every US$ 5.60 of estimated expenditure.Conclusion - The higher estimates from the BIA might cause decision makers to be more cautious with the introduction of a new medicine to reduce the opportunity costs for other interventions.

Abstract
Simple Summary Five-year survival rates from patients with locally advanced cervical cancer (LACC) are between 40% and 60%. These patients are usually treated with chemoradiation or radiotherapy in combination with hyperthermia (thermoradiation). The aim of our study was to enhance chemoradiation or thermoradiation by adding PARP1-inhibition to these conventional therapies. To study this, different cervical cancer cell lines were used to measure cell reproductive death and analyze DNA double strand breaks and cell death. By looking into the surviving fractions and DNA double strand breaks, our results suggest that PARP1-i sensitizes cervical cancer cells for the conventional therapies. The results of the live cell imaging suggest that effects are solely additive. Abstract Radiotherapy plus cisplatin (chemoradiation) is standard treatment for women with locoregionally advanced cervical cancer. Both radiotherapy and cisplatin induce DNA single and double-strand breaks (SSBs and DSBs). These double-strand breaks can be repaired via two major DNA repair pathways: Classical Non-Homologous End-Joining (cNHEJ) and Homologous Recombination. Besides inducing DNA breaks, cisplatin also disrupts the cNHEJ pathway. Patients contra-indicated for cisplatin are treated with radiotherapy plus hyperthermia (thermoradiation). Hyperthermia inhibits the HR pathway. The aim of our study is to enhance chemoradiation or thermoradiation by adding PARP1-inhibition, which disrupts both the SSB repair and the Alternative NHEJ DSB repair pathway. This was studied in cervical cancer cell lines (SiHa, HeLa, C33A and CaSki) treated with hyperthermia (42 °C) ± ionizing radiation (2–6 Gy) ± cisplatin (0.3–0.5 µM) ± PARP1-inhibitor (olaparib, 4.0–5.0 µM). Clonogenic assays were performed to measure cell reproductive death. DSBs were analyzed by γ-H2AX staining and cell death by live cell imaging. Both chemoradiation and thermoradiation resulted in lower survival fractions and increased unrepaired DSBs when combined with a PARP1-inhibitor. A quadruple modality, including ionizing radiation, hyperthermia, cisplatin and PARP1-i, was not more effective than either triple modality. However, both chemoradiation and thermoradiation benefit significantly from additional treatment with PARP1-i.

Abstract
Introduction: There are growing concerns among European health authorities regarding increasing prices for new cancer medicines, prices not necessarily linked to health gain and the implications for the sustainability of their healthcare systems.Areas covered: Narrative discussion principally among payers and their advisers regarding potential approaches to the pricing of new cancer medicines.Expert opinion: A number of potential pricing approaches are discussed including minimum effectiveness levels for new cancer medicines, managed entry agreements, multicriteria decision analyses (MCDAs), differential/tiered pricing, fair pricing models, amortization models as well as de-linkage models. We are likely to see a growth in alternative pricing deliberations in view of ongoing challenges. These include the considerable number of new oncology medicines in development including new gene therapies, new oncology medicines being launched with uncertainty regarding their value, and continued high prices coupled with the extent of confidential discounts for reimbursement. However, balanced against the need for new cancer medicines. This will lead to greater scrutiny over the prices of patent oncology medicines as more standard medicines lose their patent, calls for greater transparency as well as new models including amortization models. We will be monitoring these developments.

Abstract
Molecular-level features of tumours can be tracked using single-cell analyses of circulating tumour cells (CTCs). However, single-cell measurements of protein expression for rare CTCs are hampered by the presence of a large number of non-target cells. Here, we show that antibody-mediated labelling of intracellular proteins in the nucleus, mitochondria and cytoplasm of human cells with magnetic nanoparticles enables analysis of target proteins at the single-cell level by sorting the cells according to their nanoparticle content in a microfluidic device with cell-capture zones sandwiched between arrays of magnets. We used the magnetic labelling and cell-sorting approach to track the expression of therapeutic protein targets in CTCs isolated from blood samples of mice with orthotopic prostate xenografts and from patients with metastatic castration-resistant prostate cancer. We also show that mutated proteins that are drug targets or markers of therapeutic response can be directly identified in CTCs, analysed at the single-cell level and used to predict how mice with drug-susceptible and drug-resistant pancreatic tumour xenografts respond to therapy.

Abstract
OBJECTIVE The treatment landscape for ovarian cancer has shifted in recent years with the approval of poly ADP-ribose polymerase inhibitors in 2014. Most patients with ovarian cancer have advanced disease at diagnosis. Understanding how treatments for advanced disease work in real-world settings must be assessed to provide care for these patients. Therefore, the objective of this study was to locate and assess real-world studies measuring the safety and effectiveness of poly ADP-ribose polymerase inhibitors and analyze the results.Data sources: A targeted systematic literature review was conducted in April 2020 of PubMed/Medline. Inclusion criteria consisted of observational studies using real-world data of olaparib, rucaparib, or niraparib as an intervention in the treatment of ovarian cancer. In addition, studies needed to assess either clinical effectiveness or safety. Once studies were identified, we aimed to narratively describe the studies' patient population, intervention effectiveness, and/or safety.Data summary: Our systematic review identified six studies assessing the real-world effectiveness and/or safety of poly ADP-ribose polymerase inhibitors, with five assessing olaparib, one assessing poly ADP-ribose polymerase inhibitors as a composite, and none assessing either niraparib or rucaparib. The median progression free survival in the real-world trials for olaparib ranged from 12.7 to 15.6 months. The median overall survival in the real-world trials for olaparib ranged from 30.9 to 35.4 months. Rates of treatment discontinuation due to adverse events for olaparib ranged from 4.4% to 12.5%. CONCLUSIONS The identified studies showed slightly higher, but comparable results for median progression free survival, median overall survival, and discontinuation due to adverse events compared to the respective randomized controlled trials.

Abstract
Our objective was to assess the safety and efficacy of olaparib in maintenance therapy of BRCA 1-2 mutated, platinum-sensitive, recurrent ovarian carcinoma after the partial or complete response to the second or further lines platinum-based chemotherapy in a real-world setting. We performed a multicenter, real-world observational population-based cohort study on the whole population of Croatian patients initiated to olaparib maintenance therapy between 2016 and 2020. The primary endpoints were progression-free survival and the discontinuation of treatment because of adverse events. We enrolled the total population of 69 patients with the median (interquartile range; IQR) age of 53 (48–59), 56 (81%) of them with BRCA1 mutation. The median (IQR) follow-up was 16 (9–25) months. Treatment had to be discontinued because of toxicity in 2 (3%) and temporarily interrupted in 14 (20%), while dose was reduced because of toxicity in 18 (26%) of patients. Toxicity of any grade was observed in 61 (88%) patients and toxicity of grade 3 or 4 in 12 (17%). Median progression-free survival was 21 (95% CI 16-not calculable) months from the introduction of olaparib, and the median overall survival was not reached. Our study confirmed efficacy and safety of olaparib as the maintenance therapy of BRCA 1-2 mutated, platinum-sensitive, recurrent ovarian carcinoma. We observed the real-world efficacy and safety comparable to those observed in the randomized controlled trials. We found the interesting observation of better efficacy of 300 mg tablets, compared to 400 mg capsules, an issue that should be addressed on much larger real-world populations.

Abstract
PURPOSE The International Society of Pharmacoepidemiology (ISPE) in collaboration with the Latin America Drug Utilization Research Group (LatAm DURG), the Medicines Utilization Research in Africa (MURIA) group, and the Uppsala Monitoring Center, is leading an initiative to understand challenges to drug utilization research (DUR) in the Latin American (LatAm) and African regions with the goal of communicating results and proposing solutions to these challenges in four scientific publications. The purpose of this first manuscript is to identify the main challenges associated with DUR in the LatAm region. METHODS Drug utilization (DU) researchers in the LatAm region voluntarily participated in multiple discussions, contributed with local data and reviewed successive drafts and the final manuscript. Additionally, we carried out a literature review to identify the most relevant publications related to DU studies from the LatAm region. RESULTS Multiple challenges were identified in the LatAm region for DUR including socioeconomic inequality, access to medical care, complexity of the healthcare system, limited investment in research and development, limited institutional and organization resources, language barriers, limited health education and literacy. Further, there is limited use of local DUR data by decision makers particularly in the identification of emerging health needs coming from social and demographic transitions. CONCLUSIONS The LatAm region faces challenges to DUR which are inherent in the healthcare and political systems, and potential solutions should target changes to the system.

Abstract
Introduction There are increasing concerns regarding the inappropriate use of medicines with expenditure continuing to grow driven by increasing sales in oncology and orphan diseases, enhanced by their emotive nature. As a result, even high income countries are struggling to fund new premium priced medicines. These concerns have resulted in initiatives to better manage the entry of new medicines and enhance the rational use of medicines (RUM). However, there is a need to ascertain the current situation. We sought to address this by developing the Current Obstacles for Rationalizing Use of Medicines in Europe (CORUM) mapping tool to qualitatively investigate the current situation and provide analysis of current views on RUM and interventions among key European payers and their advisers. The findings will be used to provide future guidance. Methodology Descriptive study exploring and identifying perceived gaps to achieving optimal RUM. The CORUM tool was based on the WHO 12 key interventions to promote RUM. Results 62 participants took part with most respondents believing their country could improve RUM capacity. This included educational initiatives on the use of clinical guidelines (90%) and the inclusion of problem-based pharmacotherapy in undergraduate curricula and for Continued Professional Development. Key challenges included a lack of regular updates of guidelines, exacerbated by limited funding and a lack of follow-up to monitor adherence to agreed guidelines. RUM could also be enhanced by the development of regional formularies as well as implementing Drug and Therapeutic Committees where these are currently limited. There also needs to be greater co-ordination between RUM and Health Technology Assessment activities, with countries learning from each other. Conclusion There is an urgent need to improve RUM through improved educational and other activities among European countries, with countries learning from each other. This will involve addressing current challenges and we will be following this up.

Abstract
Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved as maintenance therapy of recurrent ovarian cancer (OC) patients with a BRCA mutation. To achieve the maximum clinical benefit, adherence to olaparib must be persistent. However, in clinical practice, this is challenged by the frequent suboptimal management of toxicities. In view of the expanding use of olaparib also in Italy, physicians must learn how to adequately and promptly manage drug toxicities not to unnecessarily interrupt or reduce the dose. The experts agreed that nausea,vomiting, anemia, and fatigue are the most frequent events experienced by OC patients on olaparib, and that these toxicities usually develop early during treatment, are mainly of grade 1-2 and transient and can be managed with simple non-pharmacological interventions. By sharing their real-world experiences, the panel prepared, for each toxicity, an algorithm organized by grade and besides the procedures indicated in the local label, included supportive care interventions based also on nutritional and lifestyle modifications and psycho-oncology consultation. Moreover, in view of the tablet entry into the Italian market, the full and reduced dosages of capsules and tablets were compared. This practical guidance is intended to be a tool to support especially less-experienced physicians in the management of these complex patients, with the aim to help preventing the worsening of patients' conditions and the unnecessary interruption/reduction of olaparib dosage, which may jeopardize treatment efficacy.

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.
