The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Bleximenib

Experimental: Bleximenib - Participants in Phase 1 Part 1 (dose escalation) will receive bleximenib orally. The dose levels will be escalated based on the dose limiting toxicities (DLT) evaluation by Study Evaluation Team (SET) until the recommended Phase 2 Doses (RP2Ds) have been identified. Participants in Phase 1 Part 2 (dose expansion) will receive bleximenib orally at the RP2D(s) determined in Part 1. Food effect cohort (optional) participants will receive bleximenib orally on Cycle 2 Day 1 under fasted condition and on Cycle 2 Day 2 under fed condition. Participants in Phase 2 part of the study will receive bleximenib orally at the RP2D level(s).


Treatment: Drugs: Bleximenib
Bleximenib is administered orally.
