Breast Cancer Clinical Trial

A Study of PRT1419 in Patients With Advanced Solid Tumors

Summary

This is a Phase 1 dose-escalation study of PRT1419, a myeloid cell leukemia 1 (MCL1) inhibitor, in patients with advanced solid tumors. The purpose of this study is to define the dosing schedule, maximally tolerated dose and/or estimate the optimal biological dose to be used in subsequent development of PRT1419.

Full Description

This is a multicenter, open-label, dose-escalation Phase 1 study of PRT1419, a MCL1 inhibitor, evaluating patients with relapsed or refractory solid tumors, including breast, lung, sarcoma and melanoma as part of a 28-day treatment cycle. The study will employ a "3+3" dose escalation design. The dose may be escalated until a dose limiting toxicity is identified.
