Official title: Phase I-II Study to Assess the Safety, Tolerability and Efficacy of PM01183 and Atezolizumab in Patients With Advanced Small Cell Lung Cancer That Progressed Following Prior Therapy With Platinum-Based Chemotherapy.

Clinical Trial Summary

Prospective, open-label, uncontrolled and multicenter phase I-II study in SCLC patients with ECOG PS 0-1 who have failed one prior platinum-containing line but no more than one chemotherapy-containing line. The study will be divided into two parts: a dose-ranging phase I with escalating doses of PM01183 in combination with a fixed dose of atezolizumab, followed by a single-arm phase II part with expansion at the RD determined during the phase I.

Clinical Trial Description

Phase I Patients will receive atezolizumab at a fixed dose of 1200 mg intravenously (i.v.) followed by PM01183 at a starting dose of 2.5 mg/m2 i.v. as a 1-hour infusion on Day 1 every three weeks (q3wk). PM01183 doses will be escalated in successive cohorts of patients following a modified Fibonacci scheme and a classical 3+3 design, and according to observed tolerance and safety.

Phase II Patients will receive atezolizumab i.v. as a 60-minute infusion (the second and subsequent infusions may be administered over 30 minutes) followed by PM01183 i.v. as a 1-hour infusion on Day 1 q3wk, at the RD determined during the phase I part.

It is expected that approximately 50% of patients included were previously treated with chemotherapy and the other 50% with immunotherapy and chemotherapy. In case one of the groups reaches 50% of the total number of patients expected to be recruited, no further patient will be included in this group and accrual will be limited to patients with the other group.

It is expected that approximately 50% of the patients included in the phase II part will be platinum-resistant [i.e., chemotherapy-free interval (CTFI) 30 to < 90 days from the end of first-line platinum-based chemotherapy] and 50% will be platinum-sensitive (i.e., CTFI ≥ 90 days), so as to assess efficacy in both settings. However in case that one of the CTFI groups reaches 60% of the total number of patients expected to be recruited, no further patient will be included in this group and accrual will be limited to patients with the other CTFI group. ;
