A Study of PRT2527 as Monotherapy and in Combination With Zanubrutinib in Participants With R/R Hematologic Malignancies

T-cell Lymphoma Clinical Trial

Official title:
A Phase 1 Open-Label, Multi-Center, Safety and Efficacy Study of PRT2527 as Monotherapy and in Combination With Zanubrutinib in Participants With Relapsed/Refractory Hematologic Malignancies

Clinical Trial Summary

This is a Phase 1 dose-escalation study of PRT2527, a potent and highly selective cyclin-dependent kinase (CDK) 9 inhibitor, in participants with select relapsed or refractory (R/R) hematologic malignancies. The purpose of this study is to evaluate the safety, tolerability, recommended phase 2 dose (PR2D), and preliminary efficacy of PRT2527 as a monotherapy and in combination with zanubrutinib.

Clinical Trial Description

This is an open-label, multi-center, dose-escalation, Phase 1 study of PRT2527, a CDK9 inhibitor, as monotherapy and in combination with zanubrutinib, a Bruton tyrosine kinase inhibitor (BTKi), evaluating participants with select R/R hematologic malignancies including aggressive B-cell lymphoma subtypes, mantle cell lymphoma (MCL), and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL), including Richter's syndrome and T-cell lymphoma (TCL) subtypes. The study will be conducted in two parts, the dose escalation phase and the dose confirmation phase for both monotherapy and combination therapy. The dose escalation phase will evaluate escalating doses of PRT2527 as a monotherapy and in combination with zanubrutinib until MTD is identified or when the RP2D is determined. The dose confirmation phase will evaluate indication-specific cohorts at the RP2D to confirm the dose. Approximately 104 participants will be enrolled in the dose escalation and indication-specific, dose confirmation cohorts. ;
