Summary

Phase Ib open label, multicenter study to evaluate the efficacy and safety of anti-PD-1 and VEGF bispecific antibody (AK112) combined with chemotherapy in patients with ES-SCLC.

Detailed description

Small cell lung cancer (SCLC) is an aggressive type of neuroendocrine tumor with the majority of patients (about 60-70%) being diagnosed with metastatic disease and with a median survival ranging from 7 to 12 months. Combination chemotherapy , namely a platinum and etoposide-based regimen, represents the cornerstone of treatment for extensive stage SCLC(ES-SCLC). Despite this the duration of response is short and nearly all patients develop disease relapse or progression. The recent approval of atezolizumab in combination with carboplatin and etoposide as first line in patients with ES- SCLC is surely a step forward in the understanding the molecular landscape and treatment of this complex tumor, but new therapeutic approaches need to be explored.This trial aims to assess the safety and efficacy of a new therapeutic strategy that combines to carboplatin and etoposide, and a new drug AK112.The treatment will start with an induction phase during which eligible patients will receive, by intravenous way, a combination of the above mentioned drugs according to a specific administration regimen. This phase will last about 12 weeks. Thereafter the treatment will proceed with a maintenence phase lasting for a maximum of 24 months during which the patients will receive only AK112, by intravenous way. Treatment will be discontnued in case of until the toxicity became intolerable, the investigator determined that there was no further clinical benefit (based on a combination of RECIST V1.1 imaging assessment and clinical status), 24 months of treatment was completed, or the study was withdrawn for other reasons. During the study period the patients will undergo to periodic visits and laboratory, radiologic assessments to monitor the efficacy and the safety of the ongoing treatment.
