Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

PM01183 w/ Atezolizumab

Patients will receive atezolizumab at a fixed dose of 1200 mg intravenously (i.v.) as a 60-minute infusion (the second and subsequent infusions may be administered over 30 minutes) 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). Following analysis of cohorts, dose levels can be escalated from 2.5mg to 3.2, to a maximum dose of 3.5 mg of PM01183

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Voluntarily signed and dated written informed consent prior to any specific study procedure.
* Age \>18 years.
* Histologically or cytologically confirmed diagnosis of extensive or limited SCLC.
* Progression to first-line platinum-based chemotherapy. For phase II part: Progression to first- line platinum-based chemotherapy or first- line platinum- based chemotherapy and immunoterapy (anti PD1/ PDL1). A chemotherapy and/ or immunotherapy- free interval (CTFI, time from the last dose of first-line chemotherapy to the occurrence of progressive disease) ≥ 30 days.
* Eastern Cooperative Oncology Group (ECOG) performance status (PS) score ≤1.
* Measurable disease according to RECIST v.1.1. Note: irradiated lesions may qualify as target if progression has been documented.
* At least three weeks since last prior anticancer treatment (including radiotherapy) and recovery to grade ≤ 1 from any adverse event (AE) related to previous anticancer treatment (excluding sensory neuropathy, anemia, asthenia and alopecia, all grade ≤ 2) according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE, v.5).
* Adequate bone marrow, renal, hepatic, and metabolic function (assessed ≤7 days before inclusion in the study):
* Platelet count ≥100 x 109/L, hemoglobin ≥9.0 g/dL and absolute neutrophil count (ANC) ≥1.5 x 109/L.
* Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3.0 x the upper limit of normal (ULN), independently of the presence of liver metastases.
* Alkaline phosphatase (AP) ≤2.5 x ULN.
* Total bilirubin ≤1.5 x ULN or direct bilirubin ≤ULN
* International Normalized Ratio (INR) \<1.5 (except if patient is on oral anticoagulation therapy).
* Calculated creatinine clearance (CrCL) ≥30 mL/minute (using Cockcroft and Gault´s formula).
* Creatine phosphokinase (CPK) ≤2.5 x ULN.
* Albumin ≥3.0 g/dL. Albumin infusion to fulfill the inclusion criterion is forbidden.
* Thyroid stimulating hormone (TSH) within institutional normal limits. If TSH is above the ULN, then a free T4 within institutional normal limits is acceptable.
* Evidence of non-childbearing status for women of childbearing potential (WOCBP). Both women and men must agree to use a highly effective contraceptive measure during the trial, for at least five months after last atezolizumab dose, and for at least six weeks (women) or 4 months (men) after last PM01183 dose. Fertile male patients with WOCBP partners must agree to refrain from fathering a child or donating sperm during the trial and up to five months after treatment discontinuation. Acceptable methods of contraception include abstinence, intrauterine device (IUD), oral contraceptive, subdermal implant and/or double barrier.
