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.

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.
