e21728 Background: Bevacizumab (bev) is a recombinant humanized monoclonal antibody that binds selectively to VEGF-A and prevents it from interacting with its receptors, thereby inhibiting formation of new tumor vasculature to block tumor growth. FKB238, a bev biosimilar, has similar pharmacokinetic and safety profiles to originator bev (o-bev). This phase 3 trial (NCT02810457) compared the efficacy and safety of FKB238 with o-bev in patients with advanced/recurrent non-squamous non-small cell lung cancer (NS-NSCLC). Methods: This global, multicenter, double-blind, parallel, randomized, comparative clinical trial enrolled and randomized 731 patients with advanced/recurrent NS-NSCLC to receive 15 mg/kg intravenous (IV) infusion of either FKB238 (N = 364) or o-bev (N = 367). All patients received IV infusions of paclitaxel (200 mg/m2) and carboplatin (AUC 6.0) immediately prior to investigational drugs for 4-6 cycles. FKB238 and o-bev were administered on day 1 of each 21-day cycle until objective progressive disease or other discontinuation criteria were met. Results: The objective response rate (ORR) based on blinded independent central review assessment for the intent-to-treat population was 51.6% and 53.7% for patients in the FKB238 and o-bev arms, respectively. The FKB238/o-bev ORR ratio was 0.96 (90% CI: 0.86 to 1.08) and the 90% CI fell within the pre-specified equivalence margin. The estimated proportion of patients alive and progression free at 12 months was 25.0% in the FKB238 arm vs 25.3% in the o-bev arm (HR of 0.97, 95% CI 0.82-1.16). The estimated median progression-free survival was 7.72 months in the FKB238 arm and 7.62 months in the o-bev arm. TEAEs were reported for 94.2% (FKB238) and 95.1% (o-bev) of patients. TEAEs ≥ grade 3 were reported for 53.6% (FKB238) and 55.5% (o-bev) of patients. SAEs were reported for 25.1% and 26.0% of patients treated with FKB238 and o-bev, respectively. Conclusions: There were no meaningful differences in efficacy and safety between FKB238 or o-bev in patients with NS-NSCLC. ORR efficacy equivalence was demonstrated, and the safety profiles of both drugs were similar. Clinical trial information: NCT02810457.

Nonsquamous Nsclc

Purpose We evaluated whether motesanib (a selective oral inhibitor of vascular endothelial growth factor receptors 1, 2, and 3; platelet-derived growth factor receptor; and Kit) combined with carboplatin/paclitaxel improved overall survival (OS) versus chemotherapy alone in patients with nonsquamous non–small-cell lung cancer (NSCLC) and in the subset of patients with adenocarcinoma. Patients and Methods Patients with stage IIIB/IV or recurrent nonsquamous NSCLC (no prior systemic therapy for advanced disease) were randomly assigned 1:1 to carboplatin (area under the curve, 6 mg/ml · min) and paclitaxel (200 mg/m2) intravenously for up to six 3-week cycles plus either motesanib 125 mg (arm A) or placebo (arm B) once daily orally. OS was the primary end point. Secondary end points included progression-free survival (PFS), objective response rate (ORR), adverse events (AEs), and association between placental growth factor (PLGF) change and OS. Results A total of 1,090 patients with nonsquamous NSCLC were randomly assigned (arms A/B, n = 541 of 549); of those, 890 had adenocarcinoma (n = 448 of 442). Median OS in arms A and B was 13.0 and 11.0 months, respectively (hazard ratio [HR], 0.90; 95% CI, 0.78 to 1.04; P = .14); median OS for the adenocarcinoma subset was 13.5 and 11.0 months, respectively (HR, 0.88; 95% CI, 0.75 to 1.03; P = .11). In descriptive analyses (arms A v B), median PFS was 5.6 months versus 5.4 months (P = < .001); ORR was 40% versus 26% (P < .001). There was no association between PLGF change and OS in arm A. The incidence of grade ≥ 3 AEs (arms A and B, 73% and 59%, respectively) and grade 5 AEs (14% and 9%, respectively) was higher with motesanib treatment. Conclusion Motesanib plus carboplatin/paclitaxel did not significantly improve OS over carboplatin/paclitaxel alone in patients with advanced nonsquamous NSCLC or in the adenocarcinoma subset.

Purpose To compare the efficacy and safety of weekly paclitaxel in combination with carboplatin administered every 4 weeks to the standard regimen of paclitaxel and carboplatin administered every 3 weeks for the treatment of patients with advanced non–small-cell lung cancer (NSCLC). Patients and Methods Four hundred forty-four patients with previously untreated stage IIIB/IV NSCLC were randomly assigned to either arm 1 (n = 223), paclitaxel 100 mg/m2 weekly for 3 of 4 weeks with carboplatin area under the curve (AUC) = 6 mg/mL · min on day 1 of each 4 week cycle, or arm 2 (n = 221), paclitaxel 225 mg/m2 and carboplatin AUC = 6 on day 1 of each 3-week cycle. After four cycles of therapy, patients in both treatment arms were eligible to continue weekly paclitaxel (70 mg/m2, 3 of 4 weeks) as maintenance therapy until unacceptable toxicity or disease progression. Results The objective response rate was 27.6% for arm 1 and 19.2% for arm 2. Median time to progression (TTP) was 18.4 and median survival (MS) was 38.6 weeks for arm 1. For arm 2, the median TTP and MS were 16.7 weeks and 42.9 weeks respectively. Grade 3/4 anemia was more common with arm 1, although grade 2/3 neuropathy and arthralgia were less common. The remainder of the toxicities were similar between the two arms. Conclusion All efficacy parameters were similar between the two treatment arms. The favorable nonhematologic toxicity profile of arm 1 makes this an alternative treatment option for patients with advanced NSCLC.

PurposeThis study evaluated the efficacy and safety of pemetrexed, carboplatin, and bevacizumab followed by maintenance pemetrexed and bevacizumab in patients with chemotherapy-naive stage IIIB (effusion) or stage IV nonsquamous non–small-cell lung cancer (NSCLC).Patients and MethodsPatients received pemetrexed 500 mg/m2, carboplatin area under the concentration-time curve of 6, and bevacizumab 15 mg/kg every 3 weeks for six cycles. For patients with response or stable disease, pemetrexed and bevacizumab were continued until disease progression or unacceptable toxicity.ResultsFifty patients were enrolled and received treatment. The median follow-up was 13.0 months, and the median number of treatment cycles was seven (range, one to 51). Thirty patients (60%) completed ≥ six treatment cycles, and nine (18%) completed ≥ 18 treatment cycles. Among the 49 patients assessable for response, the objective response rate was 55% (95% CI, 41% to 69%). Median progression-free and overall survival rates were 7.8 months (95% CI, 5.2 to 11.5 months) and 14.1 months (95% CI, 10.8 to 19.6 months), respectively. Grade 3/4 hematologic toxicity was modest—anemia (6%; 0), neutropenia (4%; 0), and thrombocytopenia (0; 8%). Grade 3/4 nonhematologic toxicities were proteinuria (2%; 0), venous thrombosis (4%; 2%), arterial thrombosis (2%; 0), fatigue (8%; 0), infection (8%; 2%), nephrotoxicity (2%; 0), and diverticulitis (6%; 2%). There were no grade 3 or greater hemorrhagic events or hypertension cases.ConclusionThis regimen, involving a maintenance component, was associated with acceptable toxicity and relatively long survival in patients with advanced nonsquamous NSCLC. These results justify a phase III comparison against the standard-of-care in this patient population.
