What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

Not stated in the study description — ask the study team about visits and procedures.

Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

In plain language

This study tests the safety of AB8939 and finds the highest dose patients can tolerate and a dose for further testing. It is for people with acute myeloid leukemia (AML), a blood cancer, that has come back or has not responded to treatment. The dose-finding part also includes some people with high-risk myelodysplastic syndrome (MDS), a disease of the bone marrow.

The primary objective is to define the safety and tolerability of AB8939 in patients with AML by determining the dose-limiting toxicities, the maximum tolerated dose, and the recommended dose for dose expansion study.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Have confirmed AML and be eligible for a second or third course of treatment.
  • For the dose-finding part, people with high-risk MDS that has not responded to treatment may also join if eligible for a second or third course of treatment.
  • For the dose-finding part, be fully active or able to do light work despite limits on hard physical activity.
  • For the later expansion part, be able to care for yourself and be up and about for more than half of waking hours, even if unable to work.
  • Be able to understand, sign, and date the consent form before any study procedures.
  • Be able and willing to follow study steps, including tests that take samples of bone marrow.
  • Other study rules may apply.

Who can't join

  • Are eligible for standard treatment.
  • Are eligible for a stem cell transplant when joining the study.
  • Have acute promyelocytic leukemia (M3), a type of AML.
  • Have active leukemia in the brain or spinal cord.
  • Had a stem cell transplant within 100 days before the first AB8939 dose.
  • Are breastfeeding or plan to breastfeed during the study.
  • Have a positive pregnancy test.
  • Other study rules may apply.
