Clinical Trial Summary

This is a multicenter, open-label study to assess the safety and preliminary efficacy and to determine the maximum tolerated dose (MTD) or maximum administration dose (MAD) and recommended Phase 2 doses (RP2D) of PRJ1-3024 in subjects with relapsed/refractory solid tumors. The study consists of two parts, one is a 3+3 dose escalation study and another is a pharmaceutical extension of RP2D.

Description:

Using dose escalation, the study will evaluate the safety, tolerability, PK, and pharmacodynamics of PRJ1-3024 and will determine the maximum tolerated dose in subjects with advanced solid tumors.

Participants with advanced solid tumor will receive PRJ1-3024 daily as an oral therapy and test the impact of of PRJ1-3024 on tumors.

This study will find the safe and tolerable recommended dose in subjects with advanced solid tumors in a open-label, 3+3 dose escalation study and use the RP2D to assess the preliminary efficacy of PRJ1-3024 in a long-term extension study.
