TGRX-678 Chinese Phase II in Chronic Myelogenous Leukemia (CML) Patients

Official title

A Single-arm, Open-label, Multi-center Phase II Study Evaluating Efficacy and Safety of TGRX-678 in CML-AP Patients Relapsed or Refractory From 3rd-generation TKI Treatment

Overview

A Phase II study evaluating the safety and efficacy of TGRX-678 in Chronic Myelogenous Leukemia (CML) patients in Accelerated phase (AP) and are relapsed or refractory from third-generation Tyrosine Kinase Inhibitor (TKI) treatment

Detailed description

This Phase II study is of single-arm, open-label and multi-center designs to study safety and efficacy profiles of TGRX-678 in CML-AP patients. Patients need to have medical history of failing treatment(s) from third-generation TKI drugs. Patients with or without T315I mutation is enrolled.

Interventions

• Drug TGRX-678
  All patients will be given TGRX-678 240 mg once daily. TGRX-678 is to be taken orally

Primary outcome measures

• Major Hematologic Response (MaHR) [Time frame: At screening, on Day 1 of every treatment cycle (each cycle is 28 days) and at end of treatment; average of study duration is 3.5 years]

Secondary outcome measures (7)

• Cytogenetic Response [Time frame: At screening, on Day 1 of cycle 2, cycle 4 and every 3 cycles afterwards of the treatment cycle (each cycle is 28 days) and at the end of treatment; average of study duration is 3.5 years]
• Major Molecular Response (MMR) [Time frame: At screening, on Day 1 of cycle 2, cycle 4 and every 3 cycles afterwards of the treatment cycle (each cycle is 28 days) and at the end of treatment; average of study duration is 3.5 years]
• Time to Response (TTR) [Time frame: At screening, on Day 1 of cycle 2, cycle 4 and every 3 cycles afterwards of the treatment cycle (each cycle is 28 days) and at the end of treatment; average of study duration is 3.5 years]
• Duration of Response (DOR) [Time frame: At screening, on Day 1 of cycle 2, cycle 4 and every 3 cycles afterwards of the treatment cycle (each cycle is 28 days) and at the end of treatment; average of study duration is 3.5 years]
• Progression Free Survival (PFS) [Time frame: At screening, on Day 1 of cycle 2, cycle 4 and every 3 cycles afterwards of the treatment cycle (each cycle is 28 days) and at the end of treatment; average of study duration is 3.5 years]
• Overall Survival (OS) [Time frame: At screening, on Day 1 of cycle 2, cycle 4 and every 3 cycles afterwards of the treatment cycle (each cycle is 28 days) and at the end of treatment; average of study duration is 3.5 years]
• Treatment Emergent Adverse Event (TEAE) [Time frame: Through completion of the study, an average of 3.5 years]
