About

The purpose of this study is to determine the safety of a short intravenous infusion of PT-523 to patients with solid tumors who have failed curative or survival prolonging therapy or for whom no such therapies exist.

Full description

The primary objectives of this study are 1) to evaluate the safety of a short intravenous infusion of PT-523 when administered on days 1, 8, and 15 of a 28-day cycle to patients with solid tumors who have failed curative or survival prolonging therapy or for whom no such therapies exist; and 2) to establish the maximum tolerated dose (MTD) and identify the dose limiting toxicities (DLT) of PT-523.

The secondary objectives of this study are to determine the pharmacokinetics and to evaluate preliminary efficacy of PT-523.
