Abstract: 

Background: RAM is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. The REVEL study evaluated the efficacy and safety of RAM+DOC vs. PL+DOC (DOC) in patients (pts) with stage IV nonsquamous (NSQ) and squamous (SQ) NSCLC after platinum-based therapy. Methods: Pts with NSQ and SQ stage IV NSCLC were randomized 1:1 (stratified by sex, region, ECOG PS, and prior maintenance therapy) to receive DOC 75 mg/m2 in combination with either RAM 10 mg/kg or PL on day 1 of a 21-day cycle until disease progression, unacceptable toxicity, or death. The primary endpoint was overall survival (OS). Secondary efficacy endpoints included progression-free survival (PFS), and objective response rate (ORR). Results: Between Dec 2010 and Feb 2013, 1,253 pts (26.2% SQ) were randomized (RAM+DOC: 628; DOC: 625). Pt characteristics were balanced between arms. ORR was 22.9% for RAM+DOC and 13.6% for DOC (P<0.001). The hazard ratio (HR) for PFS was 0.762 (P<0.0001); median PFS was 4.5 months (m) for RAM+DOC vs. 3.0m for DOC. REVEL met its primary endpoint; the OS HR was 0.857 (95% CI 0.751, 0.98; P=0.0235); median OS was 10.5m for RAM+DOC vs. 9.1m for DOC. OS was longer for RAM+DOC in most pt subgroups, including SQ and NSQ histology. Grade ≥3 adverse events (AEs) occurring in >5% of pts on RAM+DOC were neutropenia (34.9% vs. 28.0%), febrile neutropenia (15.9% vs. 10.0%), fatigue (11.3% vs. 8.1%), leukopenia (8.5% vs. 7.6%), hypertension (5.4% vs. 1.9%), and pneumonia (5.1% vs. 5.8%). Grade 5 AEs were comparable between arms (5.4% vs. 5.8%), as was pulmonary hemorrhage (any grade; all pts: 2.1% vs. 1.6%; SQ pts: 3.8% vs. 2.4%). Conclusions: REVEL demonstrated a statistically significant improvement in ORR, PFS, and OS for RAM+DOC vs DOC in NSCLC pts with stage IV NSCLC as second-line treatment after platinum-based therapy. Benefits were similar in NSQ and SQ pts, and no unexpected AEs were identified. Clinical trial information: NCT01168973.
