Brief Summary

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.

GroupInterventionDescription
Experimental: TGRX-678TGRX-678All patients with CML-AP to be treated with TGRX-678. Patients with T315I mutation or without T315I mutation will be assigned into separate cohorts for evaluation
Primary Outcome Measures
NameTimeMethod
Major Hematologic Response (MaHR)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

Number of patients who reached, and rate of occurence of major hematologic response, including those who reached complete hematologic response (CHR) or no evidence of leukemia (NEL). CHR and NEL are defined per China national treatment guideline for CML (ver. 2022). Indicators for hematologic responses will be obtained via peripheral blood tests.

Secondary Outcome Measures
NameTimeMethod
Time to Response (TTR)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

TTR defined by the time from the start of treatment to the first efficacy response; TTR as evaluated by investigator

Cytogenetic ResponseAt 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

Number of patients who reached, and rate of occurence of cytogenetic response, including those with major cytogenetic response (MCyR) or complete cytogenetic response (CCyR). Cytogenetic responses are defined per China national treatment guideline for CML (ver. 2022). Indicators for cytogenetic responses will be obtained via bone marrow biopsy.

Major Molecular Response (MMR)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

Number of patients who reached, and rate of occurence of MMR. Cytogenetic response is defined per China national treatment guideline for CML (ver. 2022). Indicators for molecular responses will be obtained via genetic testing on transcript levels of BCR-ABL gene.

Progression Free Survival (PFS)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

PFS defined as the time from enrollment to progressive disease or death of any cause; PFS as evaluated by investigator.

Overall Survival (OS)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

OS defined as the time from enrollment to death of any cause; OS as evaluated by investigator

Duration of Response (DOR)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

DOR defined as the duration from first occurence of treatment response to progressive disease/relapse; DOR as evaluated by investigator

Treatment Emergent Adverse Event (TEAE)Through completion of the study, an average of 3.5 years

To record and analyse the occurence and frequency of adverse events during the study
