Objectives

Primary purpose: To compare the efficacy of mocravimod with placebo Key secondary purposes: ‧ Compare the effect of mocravimod with placebo on overall survival (OS) ‧ Evaluate the efficacy of the second dose of mocravimod compared with placebo (if applicable) Other minor ‧ To evaluate the sustained efficacy of mocravimod compared to placebo ‧ Evaluate the effect of mocravimod on relapse compared with placebo ‧ To evaluate the effect of mocravimod on the occurrence of non-relapse death compared with placebo ‧ Compare the effect of the second dose of mocravimod on overall survival (OS) (if applicable) ‧ To evaluate the effect of mocravimod on graft-versus-host disease (GvHD) compared with placebo ‧ Evaluate the safety and tolerability of mocravimod ‧ Assessment of quality of life (QoL) after 12 months of treatment period exploratory purpose ‧ Explore the impact of mocravimod on implantation dynamics ‧ Explore the impact of mocravimod on immune system responses to various events ‧ Explore follow-up treatments after relapse ‧ Evaluate the pharmacokinetics (PK) of mocravimod and evaluate the relationship between pharmacokinetics/pharmacodynamics (PK/PD) for efficacy and safety ‧ Evaluate cyclosporine A (CsA) with mocravimod and tacrolimus (TAC) with mocravim ‧ Explore the relationship between mocravimod and hierarchical and non-hierarchical groups ‧ To explore the response and overall survival (OS) of subjects with FLT3 mutations or other genetic mutations ‧ Explore the impact of mocravimod on in-depth response
