Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with relapsed or refractory AML or high-risk MDS who have limited treatment options.

Probably not a fit

Patients with early-stage AML or MDS who are eligible for standard therapies may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label Phase 1/2 study aims to evaluate the safety, tolerability, and efficacy of APL-4098, both alone and in combination with azacitidine, for patients with relapsed or refractory acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) with excess blasts. The study will include participants who are intolerant to or ineligible for existing therapies. The Phase 1 portion will specifically focus on patients with the MDS-excess blasts subtype. The trial will assess various outcomes to determine the potential benefits of this treatment regimen.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat forms of AML and MDS.

How similar studies have gone: Other studies have shown promise with similar treatment approaches, but this specific combination is being evaluated for the first time.
