Abstract Disclosures

Abstract:

Background: Immunotherapy aiming the induction of tumor cell specific immune responses controlling the tumor growth, has emerged as a promising treatment modality in lung cancer(LuCa). Autologous DCVAC can present tumor antigens to elicit a durable immune response. We hypothesized that adding DCVAC to the standard of care chemotherapy (ct) could prolong overall survival (OS) and progression-free survival (PFS). Methods: This study evaluated the efficacy and safety of DCVAC/LuCa (active cellular immunotherapy based on dendritic cells) concomitantly added to ct (carboplatin/paclitaxel) - Arm A (A) vs DCVAC/LuCa + immune modulators (IFN-α and hydroxychloroquine) - Arm B (B)+ct vs ct - Arm C (C) in NSCLC patients (pts). Randomization 1:1:1; pts in A and B received up to 15 doses of DCVAC, ct was given 4-6 cycles in A and C. Stage IV NSCLC was confirmed histologically or cytologically, ECOG 0-1 pts were eligible. Stratification was done by histology subtype and smoking history. Primary efficacy analysis compared A vs C only as enrollment to B was closed early based on Sponsor’s assessment of further clinical development potential, there were no safety concerns or signals. Results: 112 pts at 12 sites were randomized (A/45 B/29 C/38). Patients characteristics were comparable across the study groups with the exception of gender (m/f, %: 65/35 (A) and 74/26 (C) and smoking history (75 % of smokers in A, 97 % in C). Median follow up time was 25.8 months, range 0.1-41.8. Median OS was 15.5 months in A compared to 11.8 months in C, hazard ratio (HR) 0.55, p-value 0.0232, 95% CI [0.33, 0,93], data maturity 77%. Median PFS was 6.74 in A and 5.63 months in C, HR 0.59, p-value 0.0415, 95% CI [0.36, 0.99], data maturity 86%. Overall response rate was 45% in A vs 34% in C. Most TEAEs were related to ct (anemia [35%-A, 32%-C], neutropenia [48% in A, 21%-C], thrombocytopenia [25% in A, 27% in C]). There were no grade ≥ 3 TEAEs solely related to DCVAC. Most common leukapheresis (lp)-related AE was vomiting in 2 pts out of 67 pts undergone lp. Conclusions: Addition of DCVAC-based immunotherapy to the standard of care chemotherapy significantly improved OS in stage IV NSCLC. Clinical trial information: NCT02470468
