PM534 Administered Intravenously to Patients With Advanced Solid Tumors

Официальное название

Phase I, Open-label, Dose-escalating, Clinical and Pharmacokinetic Study of PM534 Administered Intravenously to Patients With Advanced Solid Tumors

Обзор

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.

Подробное описание

This is a prospective, open-label, dose-escalating phase I study in patients with advanced solid tumors. Patients will be included in cohorts of a minimum of three or six patients to receive PM534 at successively increasing dose levels.
