A Study of BTX-A51 in People With Relapsed or Refractory Acute Myeloid Leukemia or High-Risk Myelodysplastic Syndrome
What this study is about
This is an where both patients and doctors know the treatment given, gradually increasing doses study to evaluate the safety, toxicity, and how the drug moves through the body (PK) as well as preliminary effectiveness of BTX-A51 capsules in participants with relapsed or refractory acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). The study will be done in three parts.
View original scientific description
This is an open-label, dose escalation study to evaluate the safety, toxicity, and pharmacokinetics (PK) as well as preliminary efficacy of BTX-A51 capsules in participants with relapsed or refractory acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). The study will be done in three parts. Part 1a (Monotherapy Dose Escalation) of this study is designed to determine the dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) of orally administered BTX-A51 in up to 35 participants who are evaluable for toxicity. Once the MTD is determined, it is planned that an additional 15 participants will be enrolled in Part 1b (Monotherapy Cohort Expansion) of this study for additional experience with safety and efficacy, and to determine the recommended Phase 2 dose (RP2D) which may or may not be different from the MTD. After determination of MTD and RP2D from Part 1a, Part 1c (Azacitidine Combination Dose Escalation) will enroll up to 30 participants. Continued treatment will be available under this study protocol for up to eight 28-day cycles (Continued Treatment Phase) if the Investigator judges the benefit outweighs the risk. Once BTX-A51 treatment has completed, participants will be contacted by telephone every 3 months for up to 2 years after their last treatment for survival status and anticancer therapy (Overall Survival Follow-up).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
