NCCTG N0821 (Alliance): a phase II first-line study of pemetrexed, carboplatin, and bevacizumab in elderly patients with advanced nonsquamous non-small-cell lung cancer with good performance status.

ABSTRACT: We hypothesized that the combination of bevacizumab, carboplatin, and pemetrexed will be an effective first-line regimen in fit, elderly patients with nonsquamous non-small-cell lung cancer.Treatment-naïve, stage IIIB/IV nonsquamous non-small-cell lung cancer patients more than 70 years old with good performance status (Eastern Cooperative Oncology Group performance status 0-1) and adequate organ function were eligible. Carboplatin area under the curve 6, pemetrexed 500 mg/m, and bevacizumab 15 mg/kg were administered on day 1 of each 21-day cycle (up to six cycles) followed by maintenance pemetrexed and bevacizumab. The primary end point of 6-month progression-free survival rate of at least 70% was assessed using a one-stage binomial design. Quality of life (QOL) questionnaires were administered. Polymorphisms in genes encoding relevant proteins (drug targets, transport, and metabolism proteins) were correlated with treatment outcome.Fifty-seven eligible patients were enrolled. Median age was 74.5 years. Median treatment cycles received was 6. The most common grade 3 or higher non-hematologic adverse events were fatigue (26%) and hypertension (11%); 16% had grade 4 neutropenia and 6.5% had grade 4 thrombocytopenia. Three patients experienced grade 3/4 hemorrhagic events (one pulmonary, two gastrointestinal). Primary end point of PFS6 was 60% (95% confidence interval [CI]: 45.9-73%). Median PFS was 7.0 months (95% CI: 5.9-10.1), median overall survival was 13.7 months (95% CI: 9.4-16.8). Polymorphic KDR and VEGFA variants correlated with survival and toxicity, respectively. There was no significant change in overall QOL scores over time.This regimen is feasible and did not decrease the QOL in this study population. However, it did not meet the primary efficacy end point.

Project description:IntroductionPRONOUNCE compared the efficacy and safety of pemetrexed+carboplatin followed by pemetrexed (Pem+Cb) with paclitaxel+carboplatin+bevacizumab followed by bevacizumab (Pac+Cb+Bev) in patients with advanced nonsquamous non-small-cell lung cancer (NSCLC).MethodsPatients ≥18 years of age with stage IV nonsquamous NSCLC (American Joint Committee on Cancer v7.0), and Eastern Cooperative Oncology Group performance status 0/1 were randomized (1:1) to four cycles of induction Pem+Cb (pemetrexed, 500 mg/m, carboplatin, area under the curve = 6) followed by Pem maintenance or Pac+Cb+Bev (paclitaxel, 200 mg/m, carboplatin, area under the curve = 6, and bevacizumab, 15 mg/kg) followed by Bev maintenance in the absence of progressive disease or discontinuation. The primary objective was progression-free survival (PFS) without grade 4 toxicity (G4PFS). Secondary end points were PFS, overall survival (OS), overall response rate (ORR), disease control rate (DCR), and safety. Resource utilization was also assessed.ResultsBaseline characteristics of the patients randomized to Pem+Cb (N = 182) and Pac+Cb+Bev (N = 179) were well balanced between the arms. Median (months) G4PFS was 3.91 for Pem+Cb and 2.86 for Pac+Cb+Bev (hazard ratio = 0.85, 90% confidence interval, 0.7-1.04; p = 0.176); PFS, OS, ORR, or DCR did not differ significantly between the arms. Significantly more drug-related grade 3/4 anemia (18.7% versus 5.4%) and thrombocytopenia (24.0% versus 9.6%) were reported for Pem+Cb. Significantly more grade 3/4 neutropenia (48.8% versus 24.6%), grade 1/2 alopecia (28.3% versus 8.2%), and grade 1/2 sensory neuropathy were reported for Pac+Cb+Bev. Number of hospitalizations and overall length of stay did not differ significantly between the arms.ConclusionsPem+Cb did not produce significantly better G4PFS compared with Pac+Cb+Bev. Pem+Cb was not superior in PFS, OS, ORR, or DCR compared with Pac+Cb+Bev. Both regimens were well tolerated, although, toxicity profiles differed.

Project description:ImportanceFew clinical trials have been specifically designed for elderly patients with advanced non-small cell lung cancer (NSCLC), and the anticipated increase in the number of such patients has prompted a search for new treatment options that provide a greater palliative benefit.ObjectiveTo determine whether treatment with carboplatin plus pemetrexed followed by pemetrexed maintenance is noninferior compared with docetaxel monotherapy with regard to overall survival (OS) for elderly patients with advanced nonsquamous NSCLC.Design, setting, and participantsThis open-label, multicenter, noninferiority phase 3 randomized clinical trial was conducted at 79 institutions in Japan. Cytotoxic chemotherapy-naive patients with advanced nonsquamous NSCLC, an Eastern Cooperative Oncology Group performance status of 0 or 1, and age of 75 years or older were enrolled between August 2013 and February 2017. Data were analyzed from November 2018 to February 2019.InterventionsPatients were randomized to receive either docetaxel monotherapy (60 mg/m2) every 3 weeks or 4 cycles of carboplatin (area under the curve of 5) plus pemetrexed (500 mg/m2) administered every 3 weeks followed by maintenance therapy with the same dose of pemetrexed for 3 weeks.Main outcomes and measuresThe primary end point was OS analyzed on an intention-to-treat basis with a noninferiority margin of 1.154 for the upper limit of the 95% CI of the hazard ratio (HR) estimated with a stratified Cox regression model.ResultsOf the 433 enrolled patients, 250 (57.7%) were male, and the median (range) age was 78 (75-88) years. The median OS was 15.5 months (95% CI, 13.6-18.4) in the docetaxel group (n?=?217) and 18.7 months (95% CI, 16.0-21.9) in the carboplatin-pemetrexed group (n?=?216), with a stratified HR for OS of 0.850 (95% CI, 0.684-1.056; P for noninferiority?=?.003). Progression-free survival was also longer in the carboplatin-pemetrexed group (unstratified HR, 0.739; 95% CI, 0.609-0.896). Compared with those in the docetaxel group, those in the carboplatin-pemetrexed had lower rates of leukopenia (60 of 214 [28.0%] vs 147 of 214 [68.7%]) and neutropenia (99 of 214 [46.3%] vs 184 of 214 [86.0%]) of grade 3 or 4 and of febrile neutropenia (9 of 214 [4.2%] vs 38 of 214 [17.8%]) and higher rates of thrombocytopenia (55 of 214 [25.7%] vs 3 of 214 [1.4%]) and anemia (63 of 214 [29.4%] vs 4 of 214 [1.9%]) of grade 3 or 4. Dose reductions were less frequent with carboplatin-pemetrexed.Conclusion and relevanceCarboplatin-pemetrexed treatment followed by pemetrexed maintenance is a valid option for first-line treatment of elderly patients with advanced nonsquamous NSCLC.Trial registrationUniversity Hospital Medical Information Network Clinical Trials Registry Identifier: UMIN000011460.

Project description:BACKGROUND:Despite the success of immune checkpoint and targeted therapy, many patients with melanoma ultimately require further treatment. The combination of carboplatin, paclitaxel, and bevacizumab (CPB) has demonstrated promising activity in a single-arm study. In the current study, the authors performed a randomized phase 2 study to confirm efficacy and to determine whether adding everolimus would increase the activity of the combination. METHODS:Through the North Central Cancer Treatment Group, a total of 149 patients with unresectable AJCC 6th edition stage IV melanoma were randomized from May 2010 to May 2014 to either CPB or CPB with everolimus (CPBE). The primary endpoint was progression-free survival (PFS), with secondary endpoints of overall survival (OS), response rate, and tolerability. RESULTS:The CPB and CPBE treatment arms were balanced with regard to age (median age: 59 years vs 58 years) and high lactate dehydrogenase (48% vs 51%), but were unbalanced with regard to sex (male sex: 72% vs 55%; P?=?.03). Overall, there was no difference noted with regard to PFS, with a median PFS of 5.6 months for CPB versus 5.1 months for CPBE (hazard ratio [HR], 1.14; 95% confidence interval [95% CI], 0.81-1.62 [P?=?.44]), or for OS, with a median OS of 14.5 months for CPB versus 10.8 months for CPBE (HR, 1.16; 95% CI, 0.84-1.84). The confirmed response rate was 13% for CPB and 23% for CPBE (P?=?.13). Toxicity was higher for CPBE compared with CPB (83% for grade 3?+?and 14% for grade 4?+?vs 63% for grade 3?+?and 11% for grade 4+, respectively) (toxicities were graded using the Cancer Therapy Evaluation Program of the National Cancer Institute Common Terminology Criteria for Adverse Events [version 4.0]). Common grade 3?+?toxicities were neutropenia, leukopenia, and fatigue, which occurred in both treatment arms with comparable frequency. CONCLUSIONS:Both experimental arms demonstrated activity, with a PFS of >5 months. However, the addition of everolimus to CPB failed to improve outcomes, with increased toxicity noted. These findings replicate the moderate antitumor activity of CPB, with future development possibly in combination with targeted or immunotherapy.
