Abstract 5997
Background
Advanced small cell lung cancer (SCLC) remains a disease with dismal prognosis and new therapeutics are urgently needed.
SCLC is notably chemosensitive and first-line chemotherapy with platinum analogs and etoposide is associated with high rates of initial objective responses that unfortunately do not last long.
This initial tumor shrinkage provokes neoantigen release in the circulation, sometimes clinically expressed as “tumor lysis syndrome”, rendering thus the disease potently immunogenic.
We hypothesized that initial chemotherapy with two cycles of cisplatin-etoposide may trigger tumor lysis and subsequent release of neo-antigens that may in turn enhance immune responses against tumor cells with the addition of an anti-PD-L1 monoclonal antibody, such as avelumab.
Trial design
PAVE (Phased Avelumab combined with chemotherapy as first-line treatment for patients with advanced small-cell lung cancer) is a Greek, investigator- initiated, single arm open- label phase II study of Avelumab in combination with cisplatin or carboplatin/ etoposide. The study will include an initial safety run-in, open-label, single arm part (Part 1), and the actual phase II study (Part 2). The total number of patients will not change (the safety run-in patients will be included in the final total number of participants). The safety run-in period will not alter the total study timelines, as phase II accrual will follow immediately after the safety run-in. Eligible patients will receive: The standard 1st-line therapy for advanced small cell lung cancer, consisting of: Cisplatin 80 mg/m2 or Carboplatin 5 AUC D1 q three weeks for 4-6 cycles Etoposide 100 mg/m2 D1-D3 every three weeks for 4-6 cycles and Avelumab 10 mg/kg q 2 weeks will be given as a 1 hour intravenous infusion (IV) every two weeks starting from the third chemotherapy cycle until chemotherapy completion and as maintenance treatment every two weeks (q 2 weeks) thereafter until disease progression.
