RESUMEN

OBJECTIVE: To analyze the safety and efficacy of niraparib in patients aged ≥70 years with recurrent ovarian cancer in the ENGOT-OV16/NOVA trial. METHODS: The trial enrolled 2 independent cohorts with histologically diagnosed recurrent ovarian, fallopian tube, or peritoneal cancer who responded to platinum rechallenge, on the basis of germline breast cancer susceptibility gene mutation (gBRCAmut) status. Patients were randomized 2:1 to receive niraparib (300 mg) or placebo once daily until disease progression. The primary endpoint was progression-free survival (PFS) by blinded independent central review. Adverse events (AEs) of special interest were based on the known safety profile of poly(ADP-ribose) polymerase inhibitors. RESULTS: Patients aged ≥70 years in the gBRCAmut cohort receiving niraparib (n = 14) had not yet reached a median PFS compared with a median PFS of 3.7 months for the same age group in the placebo arm (hazard ratio [HR], 0.09 [95% confidence interval (CI), 0.01 to 0.73]). Non-gBRCAmut patients aged ≥70 years receiving niraparib (n = 47) had a median PFS of 11.3 months compared with 3.8 months in the placebo arm (HR, 0.35 [95% CI, 0.18 to 0.71]). Median duration of follow-up in the niraparib arm was 17.3 months in patients ≥70 years and 17.2 months in patients <70 years. Frequency, severity of AEs, and dose reductions in the niraparib arm were similar in patients aged <70 and ≥ 70 years population. The most common grade ≥ 3 AEs in patients ≥70 years were hematologic: thrombocytopenia event (34.4%), anemia event (13.1%), and neutropenia event (16.4%). CONCLUSIONS: For patients ≥70 years of age receiving niraparib as maintenance treatment in the ENGOT-OV16/NOVA trial, PFS benefits and incidence of any grade or serious treatment-emergent AEs were comparable to results in the younger population. Use of niraparib should be considered in this population.

RESUMEN

PURPOSE: Bevacizumab used in combination with first-line chemotherapy confers an overall survival (OS) benefit for patients with non-squamous non-small-cell lung cancer (NSCLC). This analysis from the ARIES observational cohort study (OCS) was initiated to evaluate the effect of bevacizumab use beyond disease progression (BBP) on clinical outcomes in patients with NSCLC receiving first-line treatment with bevacizumab and chemotherapy. METHODS: The ARIES OCS prospectively enrolled patients from 2006 to 2009 in the United States who had advanced non-squamous NSCLC, received bevacizumab with chemotherapy in the first-line setting, and survived progressive disease (PD). A dichotomous landmark analysis examined post-PD OS (ppOS) in patients who received BBP versus no BBP within 30 days post PD. A time-dependent Cox model assessed the effect of cumulative BBP exposure on ppOS. RESULTS: The ARIES OCS enrolled 1967 patients with first-line NSCLC; 1358 patients had first PD and were alive at the 30-day landmark (351 patients with BBP and 1007 patients with no BBP). The landmark analysis showed that BBP was associated with a lower risk of death (BBP versus No-BBP); hazard ratio [HR], 0.75; 95% confidence interval 0.65-0.86. In the cumulative exposure analysis of 1461 patients who had PD, HRs for ppOS decreased by approximately 4% for each additional 21-day interval of bevacizumab received. Protocol-specified bevacizumab-select adverse events occurred in 14% of BBP patients. CONCLUSIONS: BBP was associated with a lower risk of death in patients with NSCLC treated with first-line bevacizumab and chemotherapy. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMEN

PURPOSE: In the ENGOT-OV16/NOVA trial (ClinicalTrials.gov identifier: NCT01847274), maintenance therapy with niraparib, a poly(ADP-ribose) polymerase inhibitor, prolonged progression-free survival in patients with platinum-sensitive, recurrent ovarian cancer who had a response to their last platinum-based chemotherapy. The objective of the study was to assess the clinical benefit and patient-reported outcomes in patients who had a partial response (PR) and complete response (CR) to their last platinum-based therapy. PATIENTS AND METHODS: A total of 553 patients were enrolled in the trial. Of 203 patients with a germline BRCA mutation (gBRCAmut), 99 had a PR and 104 had a CR to their last platinum-based therapy; of 350 patients without a confirmed gBRCAmut (non-gBRCAmut), 173 had a PR and 177 had a CR. Post hoc analyses were carried out to evaluate safety and the risk of progression in these patients according to gBRCAmut status and response to their last platinum-based therapy. Ovarian cancer-specific symptoms and quality of life were assessed using the Functional Assessment of Cancer Therapy-Ovarian Symptom Index. RESULTS: Progression-free survival was improved in patients treated with niraparib compared with placebo in both the gBRCAmut cohort (PR: hazard ratio [HR], 0.24; 95% CI, 0.131 to 0.441; P < .0001; CR: HR, 0.30; 95% CI, 0.160 to 0.546; P < .0001) and the non-gBRCAmut cohort (PR: HR, 0.35; 95% CI, 0.230 to 0.532; P < .0001; CR: HR, 0.58; 95% CI, 0.383 to 0.868; P = .0082). The incidence of any-grade and grade 3 or greater adverse events was manageable. No meaningful differences were observed between niraparib and placebo in PR and CR subgroups with respect to patient-reported outcomes. CONCLUSION: Patients achieved clinical benefit from maintenance treatment with niraparib regardless of response to the last platinum-based therapy.

RESUMEN

BACKGROUND: Real-world evidence is lacking on the impact of bevacizumab added to carboplatin/paclitaxel (Bev + CP) therapy versus CP alone for patients with non-squamous non-small cell lung cancer (NS-NSCLC), particularly in those excluded from clinical trials. METHODS: This is a retrospective electronic medical record analysis of patients who received first-line therapy with Bev + CP or CP between 1 October 2006 and 30 June 2013. We identified four subsets: elderly patients (≥65 years), patients with brain/central nervous system (CNS) metastases, patients with Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2, and patients receiving anticoagulation. We used descriptive statistics to describe patient characteristics and treatment patterns and evaluated progression-free survival (PFS) and overall survival (OS) using survival analyses. RESULTS: The study included 431 patients (Bev + CP: 231; CP: 200). The Bev + CP cohort was more likely to receive four or more cycles of induction therapy (72 vs. 50 %) and was more likely to receive maintenance therapy (45 vs. 21 %) than patients receiving CP. In the overall population, median PFS and OS were significantly longer in the Bev + CP cohort than in the CP cohort: 6.7 vs. 5.1 months (hazard ratio [HR] 0.74; 95 % confidence interval [CI] 0.59-0.92; p = 0.008) and 11.9 vs. 9.0 months (HR 0.57; 95 % CI 0.44-0.73; p < 0.001), respectively. Treatment with Bev + CP in patients aged ≥65 years and in those with brain/CNS metastases was also associated with a significant risk reduction in PFS (35 and 51 %, respectively; p < 0.05 for both) and OS (46 and 62 %, respectively; p < 0.05 for both) compared with CP alone. CONCLUSION: Bev + CP is associated with a significant improvement in PFS and OS in patients with NS-NSCLC and in subsets with brain/CNS metastases and those aged ≥65 years.

RESUMEN

BACKGROUND: Patient-level data from 2 phase III studies in patients with previously untreated, advanced-stage, nonsquamous non-small cell lung cancer (NSCLC) were pooled to examine outcomes with bevacizumab and chemotherapy based on age. METHODS: Data from patients randomized to paclitaxel-carboplatin (PC)+bevacizumab in the Eastern Cooperative Oncology Group 4599 (E4599) and PointBreak studies were pooled and compared with E4599 patients randomized to PC alone. Patients were grouped by age: below 65, 65 to 74, 70 to 74, below 75, and 75 years or above. A multivariable model was used to calculate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using time-to-event outcomes. Adverse events (AEs) were assessed by age group in each study. RESULTS: The PC+bevacizumab and PC arms comprised 901 and 444 patients, respectively. PC+bevacizumab was associated with significant increases in overall survival relative to PC in patients below 65 years (hazards ratio [HR], 0.75; 95% confidence interval [CI], 0.62-0.89), 65 to 74 years (HR, 0.80; 95% CI, 0.64-1.00), 70 to 74 years (HR, 0.68; 95% CI, 0.48-0.96), and below 75 years (HR, 0.78; 95% CI, 0.68-0.89) but not in those aged 75 years or above (HR, 1.05; 95% CI, 0.70-1.57). Increased incidence of grade ≥3 AEs was reported with PC+bevacizumab versus PC in patients below 75 years (63% vs. 48%; P<0.05) and 75 years or above (81% vs. 56%; P <0.05) in E4599. CONCLUSIONS: This analysis suggests that the survival benefits associated with PC+bevacizumab extend to patient subgroups below 75 years with advanced-stage NSCLC; no benefit, however, was observed for bevacizumab-eligible patients who were 75 years or above.

RESUMEN

Data from randomized, controlled trials suggest that post-induction phase (IP) treatment with bevacizumab may benefit patients with advanced non-small-cell lung cancer (NSCLC). Real-world clinical practice, however, can involve variable use and patterns of treatment in broader patient populations. To assess the effect of bevacizumab on post-IP overall survival (OS) following IP chemotherapy + bevacizumab, analyses were conducted in patients enrolled in the Avastin(®) Registry--Investigation of Effectiveness and Safety (ARIES) observational cohort study (OCS) who received post-IP bevacizumab. ARIES was a large, prospective OCS of patients who received chemotherapy in combination with bevacizumab for the first-line treatment of NSCLC. This unplanned, post hoc analysis included patients who received chemotherapy and bevacizumab and who did not have progressive disease through the completion of IP treatment. A dichotomous analysis compared outcomes in patients who did and did not receive bevacizumab before a landmark date of day 30 post IP. A cumulative exposure analysis used a time-dependent Cox regression model to assess the effect of cumulative post-IP bevacizumab exposure on post-IP OS. In the dichotomous analysis, the duration of post-IP OS was significantly longer in patients who received post-IP bevacizumab; median post-IP OS was 15.6 vs. 11.3 months, respectively (hazard ratio [HR] = 0.80; 95 % confidence interval 0.71-0.91; P < 0.001). The cumulative exposure analysis observed that each additional cycle of cumulative bevacizumab exposure decreased the HR for post-IP OS by 2.7 %, on average. In conclusion, post-IP bevacizumab exposure was associated with improved post-IP OS in patients with advanced NSCLC who were enrolled in the ARIES OCS.

RESUMEN

OBJECTIVE: The use of bevacizumab in advanced non-squamous non-small cell lung cancer (NSCLC) is controversial among elderly patients. This study aimed to compare overall survival for Medicare patients diagnosed with NSCLC and treated with either first-line bevacizumab-carboplatin-paclitaxel (BCP) or carboplatin-paclitaxel (CP). METHODS: Patients ≥ 65 years old, first diagnosed with non-squamous NSCLC stage IIIB/IV between 2006 and 2009, and treated with either first-line BCP or CP, were selected from the SEER-Medicare database that links cancer registry and US Medicare claims data. Kaplan-Meier estimates were used to evaluate survival. Multivariable Cox proportional hazards models were used to compare the effect of BCP versus CP on the hazard of death. Age-stratified analyses were conducted for patients aged 65-74 and ≥ 75 years. RESULTS: Of 1706 patients in the study sample, 592 (34.7%) received BCP and 1114 (65.3%) received CP; 692 (40.6%) were ≥ 75 years. Adjusted median survival time in the BCP versus CP cohorts was 10.5 versus 8.5 months (p = 0.008). The difference in median survival favoring the BCP cohort was statistically significant for both patients aged ≥ 75 years (2.8 months, p = 0.019), and patients aged 65-74 years (1.5 months, p = 0.018). The adjusted hazard of death did not differ between the cohorts (HR: 0.96, 95% CI: 0.86-1.06); however, during the first year of follow-up, when most deaths (>60%) occurred, the hazard of death was 18% lower for the BCP cohort (HR: 0.82, 95% CI: 0.71-0.94). BCP patients also had 18% fewer hospital admissions than CP patients (adjusted incidence rate ratio (IRR): 0.82, 95% CI: 0.72-0.94) and 23% fewer inpatient days (IRR: 0.77, 95% CI: 0.65-0.91). CONCLUSIONS: In this retrospective analysis of Medicare patients in the SEER database, first-line therapy with BCP was associated with longer survival and fewer hospitalizations than CP.

RESUMEN

INTRODUCTION: Bevacizumab, a recombinant humanized monoclonal antibody against vascular endothelial growth factor, was approved by the US Food and Drug Administration for the treatment of advanced non-small-cell lung cancer (NSCLC) in combination with carboplatin and paclitaxel. ARIES (Avastin Regimens: Investigation of Effectiveness and Safety), a prospective observational cohort study, evaluated outcomes in a large, community-based population of patients with first-line NSCLC. METHODS: From 2006 to 2009, ARIES enrolled patients with locally advanced or metastatic NSCLC who were eligible for bevacizumab, excluding those with predominantly squamous histology. Patients were required to provide informed consent and to have initiated bevacizumab with chemotherapy within 4 months before enrollment. There were no protocol-defined treatments or assessments. The dosing of bevacizumab and chemotherapy, and the choice of chemotherapy regimen, was at the discretion of the treating physician. RESULTS: ARIES enrolled 1967 patients with first-line NSCLC. At study closure, median follow-up was 12.5 months (range, 0.2-65.5). Median age was 65 years (range, 31-93), and 252 patients (12.8%) identified as never smokers. Median progression-free survival was 6.6 months (95% confidence interval, 6.3-6.9), and median overall survival was 13.0 months (95% confidence interval, 12.2-13.8) with first-line bevacizumab plus chemotherapy. Incidences of bevacizumab-associated adverse events (19.7% overall) were consistent with those in randomized controlled trials of bevacizumab in NSCLC. CONCLUSION: Results from ARIES demonstrate similar outcomes to randomized controlled trials of bevacizumab when added to standard chemotherapy in a real-world patient population with advanced NSCLC.
