Summary

This trial tests AB8939, a new drug, for safety and effectiveness in patients with certain blood cancers that haven't responded to other treatments. The study will determine the best dose and schedule for future trials.

Who is the study for?
This trial is for adults with Acute Myeloid Leukemia or high-risk Myelodysplastic Syndromes who've had previous treatments fail. They must be in good physical condition (ECOG ≤ 1), able to consent, and follow study procedures like bone marrow biopsies. It's not for those eligible for standard care, stem cell transplant, have certain leukemia types or CNS involvement, recent transplants, or are pregnant/breastfeeding.
What is being tested?
The trial tests AB8939's safety and tolerability in patients with AML by finding the highest dose they can take without serious side effects. Participants will also receive Azacitidine as part of the treatment regimen.
What are the potential side effects?
Specific side effects aren't listed but generally include reactions related to drug tolerance levels such as fatigue, nausea, blood count changes, and potential organ-specific toxicity which will be monitored closely.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Acute Myelogenous Leukemia (AML) include cytotoxic therapies like cytarabine and daunorubicin, which disrupt DNA synthesis and function, leading to cell death. These treatments target rapidly dividing cells, including cancerous ones. Targeted therapies, such as FLT3 and IDH inhibitors, focus on specific genetic mutations or abnormal proteins that drive AML cell growth. These therapies aim to minimize damage to normal cells while effectively targeting cancer cells. Understanding these mechanisms helps in selecting the most appropriate treatment, potentially improving outcomes and reducing side effects for AML patients.
