Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Description of intervention(s) / exposure
Treatment: Drugs - Tuspetinib
Treatment: Drugs - Venetoclax Oral Tablet
Treatment: Drugs - Azacitidine for Intravenous Infusion

Experimental: Part A Dose Escalation [COMPLETED] - Part A dose escalation of tuspetinib as a single agent is planned for up to 6 dose levels. If a study participant in dose escalation at any dose level achieves clinical response, then the dose level will continue to enroll in Part B. If one DLT or less is observed in the 6 participants (\<1/6 DLT observed) in Part A, up to 20 evaluable participants can be enrolled in Part B at that dose level.

Experimental: Part B Dose Exploration [ACTIVE, NOT RECRUITING] - Part B dose exploration of tuspetinib as a single agent is planned for up to 4 dose levels.

Experimental: Part C Dose Expansion (tuspetinib as a single agent) [ACTIVE, NOT RECRUITING] - Part C dose expansion of tuspetinib as a single agent is planned for 2 dose levels. Study participants will be randomly assigned to either arm based on the number of slots available. The initial tuspetinib dose will be 120 mg.

Experimental: Part C Dose Expansion (tuspetinib plus venetoclax) [ACTIVE, NOT RECRUITING] - Part C dose expansion of tuspetinib in combination with venetoclax is planned for 2 dose levels. The initial tuspetinib dose will be 80 mg.

Experimental: Part D Dose Exploration (tuspetinib plus venetoclax and azacitidine) [ACTIVE, NOT RECRUITING] - Part D dose exploration of tuspetinib in combination with venetoclax and azacitidine is planned for up to 6 dose levels. The initial tuspetinib dose will be 40 mg.
