PRT3789 Monotherapy and in Combo w/Docetaxel in Participants w/Advanced or Metastatic Solid Tumors w/SMARCA4 Mutation

Advanced Solid Tumor Clinical Trial

Official title:
A Phase 1 Open-Label, Multi-Center, Safety and Efficacy Study of PRT3789 as Monotherapy and in Combination With Docetaxel in Participants With Advanced or Metastatic Solid Tumors With a SMARCA4 Mutation

Clinical Trial Summary

This is a Phase 1 dose-escalation study of PRT3789, a SMARCA2 degrader, in participants with advanced or metastatic solid tumors with loss of SMARCA4 due to truncating mutation and/or deletion. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) of PRT3789 monotherapy and in combination with docetaxel, describe any dose limiting toxicities (DLTs), define the dosing schedule, and to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) to be used in subsequent development of PRT3789.

Clinical Trial Description

This is an open-label, multi-center, dose-escalation, first in human, Phase 1 study of PRT3789 as monotherapy and in combination with docetaxel, a SMARCA2 degrader, evaluating participants with advanced or metastatic solid tumors with loss of SMARCA4 due to truncating mutation and/or deletion. The study will evaluate escalating doses of PRT3789 until the MTD or RP2D is determined. Taking into account pharmacokinetic and pharmacodynamic data from the preceding dose levels, the dose may be escalated until a dose limiting toxicity is identified. Approximately 118 participants will be enrolled in monotherapy, dose escalation, backfill, and combination cohorts. ;
