Title

Randomized, double-blind, placebo-controlled, multicenter Phase III study to evaluate the efficacy and safety of mocravimod as adjunctive and maintenance treatment in adult AML patients undergoing allogeneic HCT.

Study Overview

Allogeneic HCT is a standard treatment of curative intent for AML. A major limitation for successful outcome of allogeneic HCT is disease relapse. The graft-versus-leukemia (GvL) effect is also critical to prevent disease relapse and is mediated by donor T cells contained in the HCT graft that trigger immune responses against leukemic cells.

Mocravimod is an oral S1P receptor (S1PR) modulator that blocks lymphocyte egress from lymphoid organs via its phosphorylated active metabolite. Mocravimod’s potential to preserve the desirable GvL effect while decreasing GvHD is a promising way to maintain the prospect of a cure while decreasing transplant-related mortality (TRM) and morbidity in AML patients undergoing allogeneic HCT.

Study Design

This is a multicenter, randomized, double-blinded, placebo-controlled trial.

Purpose

The purpose of this pivotal study is to assess the efficacy and safety of mocravimod compared to standard of care as an adjunctive and maintenance treatment for allogeneic hematopoietic cell transplantation (HCT). Mocravimod is administered in addition to standard of care GvHD prophylaxis in adult high-risk AML patients.
