    119P - A phase 2 randomized open-label study of ramucirumab (RAM) plus first-line platinum-based chemotherapy in patients (pts) with recurrent or advanced non-small cell lung cancer (NSCLC): Final results from squamous pts (ID 174)

    • Abstract

    Background:
    Vascular endothelial growth factor receptors (VEGFR) and their ligands are key regulators of angiogenesis and implicated in pathogenesis of NSCLC. RAM, a human IgG1 monoclonal antibody, specifically binds to VEGFR-2 thereby preventing receptor activation and angiogenesis. In a phase 2 trial (NCT01160744) addition of RAM to platinum-pemetrexed chemotherapy demonstrated clinical activity and acceptable safety in pts with advanced non-squamous NSCLC; here we report data from squamous (SQ) NSCLC pts treated with RAM in combination with first-line gemcitabine plus platinum chemotherapy.
    
    Methods:
    Eligible pts had Stage IV SQ NSCLC, ECOG PS ≤ 2, and no prior VEGF/VEGFR therapy nor chemotherapy for stage IV disease. Pts were randomized 1:1 into either Arm C: gemcitabine 1000 mg/m[2] + carboplatin AUC=5/cisplatin 75 mg/m[2] (GEM + Cb/Cis) or Arm D: ramucirumab 10 mg/kg + gemcitabine + carboplatin/cisplatin (RAM + GEM + Cb/Cis). Pts received first-line therapy from 4 to 6 cycles (21-day cycle); patients in Arm D, in absence of progressive disease, entered a maintenance phase with RAM alone. Primary objective was progression-free survival (PFS). Secondary endpoints were overall survival (OS), objective response rate (ORR), disease control rate (DCR), change in tumor size (CTS), duration of response and safety.
    
    Results:
    140 pts were randomized (GEM + Cb/Cis: 69; RAM + GEM + Cb/Cis: 71). The median PFS was 5.4 m GEM + Cb/Cis and 5.6 m for RAM + GEM + Cb/Cis; HR 0.88 (90% CI, 0.64, 1.22; p = 0.52). Median OS was 11.3 m for GEM + Cb/Cis and 10.4 m for RAM + GEM + Cb/Cis; HR 0.93 (90% CI, 0.68, 1.27; p = 0.68). ORR was significantly improved in RAM + GEM + Cb/Cis (46.5%) compared to GEM + Cb/Cis (24.6%) (p = 0.007). No statistically significant difference was observed in DCR and CTS between the two arms. Grade ≥ 3 adverse events occurring in > 10% of pts on RAM administered arm were: anemia, neutropenia and thrombocytopenia.
    
    Conclusions:
    The primary endpoint of PFS was not met. The addition of RAM to GEM + Cb/Cis significantly improved ORR in pts with SQ NSCLC with no new unexpected safety findings.

    120P - Subgroup analysis of adenocarcinoma patients refractory to first-line chemotherapy from REVEL: A randomized phase III study of docetaxel with ramucirumab or placebo for second-line treatment of stage IV non–small cell lung cancer (NSCLC) (ID 423)

    • Abstract

    Background:
    In the phase III REVEL trial, ramucirumab plus docetaxel significantly improved median overall survival (OS), median progression-free survival (PFS), and objective response rate (ORR) in patients with advanced NSCLC who progressed after first-line platinum therapy, independent of histology. The REVEL trial also showed that ramucirumab plus docetaxel therapy improved median OS, median PFS, and ORR in adenocarcinoma patients who were refractory to first-line platinum therapy and in patients categorized as rapid progressors. Here, we report safety and quality of life (QoL) outcomes in refractory adenocarcinoma patients who participated in the REVEL trial.
    
    Methods:
    Patients were refractory if they had a best response of progressive disease to first-line treatment. Patients were randomized 1:1 to receive docetaxel 75 mg/m[2] in combination with either ramucirumab 10 mg/kg or placebo every 21 days until disease progression, unacceptable toxicity, or death. Treatment-emergent adverse events (TEAEs) were assessed according to the NCI-CTCAE, version 4.0. Quality of life was measured by the Lung Cancer Symptom Scale (LCSS).
    
    Results:
    Of the 1253 patients randomized (ramucirumab + docetaxel: 628; docetaxel + placebo: 625), 17% (ramucirumab + docetaxel: 9%; docetaxel + placebo: 8%) were adenocarcinoma patients refractory to first-line therapy. The safety overview and LCSS scores are presented in the table.rnTable: 120PSafety and QoL Outcomes of Refractory Adenocarcinoma Patients Treated in REVELrn

    Conclusions:
    Our analysis did not identify any new safety concerns or increased detriment in QoL for this subgroup of patients. Safety outcomes for refractory adenocarcinoma patients were consistent with the outcomes for refractory patients with all histologies and the intent-to-treat population.
