Clinical trials

The main purpose of the study is to evaluate the safety, tolerability and recommended dose of PM54 in combination with pembrolizumab. To assess the antitumor activity of PM54 in combination with pembrolizumab in terms of clinical benefit rate (CBR) and objective response rate (ORR) based on investigator's assessment in participants in other cohorts.

The primary purpose of this study is to evaluate the safety, tolerability and recommended dose (RD) of PM54 in combination with cytotoxic and targeted anticancer agents in adult participants with advanced solid tumors. The study will also assess the antitumor activity of PM54 in combination with cytotoxic and targeted anticancer agents in terms of objective response rate (ORR) based on investigator's assessment in participants in other cohorts.

The first part of the study (phase Ia - dose escalation) will evaluate the safety and tolerability and identify the dose-limiting toxicities (DLTs) of PM54. The second part of the study (phase Ib - safety run-in and expansion) will be to reassess the maximum tolerated dose (MTD) defined in the Phase Ia stage in a framework of more extensive premedication, and to evaluate the antitumor activity of PM54 according to the RECIST v.1.1 (or mRECIST v.1.1 in case of MPM) and/or serum markers as appropriate, in patients with selected advanced solid tumors.

The goals of this trial are to identify the dose limiting toxicities, to determine the maximum tolerated dose and the recommended dose of PM534 in patients with advanced solid tumors. All Patients will receive PM534 via intravenous.
