Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 75 with high-risk or intermediate-risk AML who are planning to undergo allogeneic HCT.

Probably not a fit

Patients with certain pre-existing conditions or those receiving specific GvHD prophylaxis treatments 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 multi-center, randomized, double-blinded, placebo-controlled trial aims to evaluate the efficacy and safety of mocravimod as an adjunctive and maintenance treatment for adult patients with acute myeloid leukemia (AML) who are undergoing allogeneic hematopoietic cell transplantation (HCT). The study will include patients diagnosed with high-risk or intermediate-risk AML and will assess the impact of mocravimod on treatment outcomes compared to a placebo. Participants will be monitored for safety and efficacy throughout the trial period.

Why it matters

Potential benefit: If successful, this treatment could improve outcomes and reduce relapse rates in AML patients undergoing transplantation.

How similar studies have gone: Other studies have shown promise with similar approaches in AML treatment, but the specific use of mocravimod in this context is novel.
