Conditions
Brief summary
A Phase III study evaluating the safety and efficacy of TGRX-678 in CML-CP patients resistant from or intolerant to at least 3 TKIs
Detailed description
This Phase III study is of randomized, open-label and multi-center designs to study safety and efficacy profiles of TGRX-678 in CML-CP patients. Patients need to have medical history of failing treatment(s) from at least 3 TKI drugs. Patients with or without T315I mutation is enrolled. Patients are randomized to either TGRX-678 treatment or TKI treatment at investigator's decision.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Event-free survival (EFS) | from randomization to occurance of any of the above-mentioned events (estimated study duration: 5 years) | EFS measures time duration between randomization to disease progression, treatment failure, loss of efficacy, development of new mutation, or death, whichever occurs first |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hematologic Response | From randomization to end of study (estimated study duration: 5 years) | Rate of occurence of complete hematologic response (CHR). |
| Cytogenetic Response | from randomization to end of study (estimated study duration: 5 years) | Rate of occurence of Major Cytogenetic Response (MCyR) and Complete Cytogenetic Response (CCyR). |
| Molecular Response | from randomization to end of study (estimated study duration: 5 years) | Rate of Occurence for Major Molecular Response (MMR) |
| Progression Free Survival (PFS) | from randomization to end of study (estimated study duration: 5 years) | Duration between enrollment to progressive disease or death of any cause |
| Overall Survival (OS) | from randomization to end of study (estimated study duration: 5 years) | Duration between enrollment to death of any cause |
| Treatment Emergent Adverse Event (TEAE) | from randomization to end of study (estimated study duration: 5 years) | To record and analyse the occurence and frequency of adverse events during the study |
