TGRX-814 Chinese Phase I/II in Patients With Hematological Malignancies

Phase 2RecruitingNCT06206174

Shenzhen TargetRx Co., Ltd.30 enrolled

Overview

The purpose of this single- arm, open-label, dose escalation and dose expansion phase I/II study is to evaluate the safety, tolerability, pharmacokinetic and preliminary efficacy of TGRX-814 in patients with hematological malignancies including non-Hodgkin lymphoma, acute myeloid leukemia, aute lymphoblastic leukemia and myelodysplastic syndromes.

This is the first-in-human trial with TGRX-814 which aims to evaluate the safety, pharmacokinetic and preliminary efficacy profiles with hematological malignancies. The primary purpose of this study is to evaluate the safety profile of TGRX-814 in patients with non-Hodgkin lymphoma and to determine of the maximal tolerated dose (MTD) and recommended phase II dose (RP2D). Other purposes of the study include evaluating safety and preliminary efficacy of TGRX-814 monotherapy and combination therapy in patients with other types of hematological malignancies, including acute myeloid leukemia, aute lymphoblastic leukemia and myelodysplastic syndromes, as well as evaluating the pharmacokinetic profile of TGRX-814. The study is a phase I/II study, consisting a monotherapy dose escalation study, monotherapy dose expansion study and combination therapy study.
