Study of Mana 312 (Multi Tumor-Associated Antigen T Cells) in Adults With AML/MDS After HSCT

AML/MDS Clinical Trial

Official title: Ph 1 Study of Escalating Single & Multiple Doses of Mana 312 (Multi Tumor-Associated Antigen T Cells) Administered to Adult Subjects With Acute Myeloid Leukemia or Myelodysplastic Syndrome After Allogeneic Hematopoietic Stem Cell Transplant

Status Terminated

Clinical Trial Summary

This is a Phase 1, open-label, non-randomized, single and multiple dose escalation study designed to evaluate the safety and preliminary efficacy of administering Mana 312 to subjects with AML/MDS after allogeneic HSCT.

Clinical Trial Description

This is a Phase 1, open-label, non-randomized, single and multiple dose escalation study designed to evaluate the safety and preliminary efficacy (prevention of, or treatment of relapse) of administering Mana 312 to subjects with AML/MDS after allogeneic HSCT. The study will evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of single and multiple doses of Mana 312. Each cycle of administration of Mana 312 will be 28 days. In the Escalation Cohorts, subjects with low, intermediate, and adverse/high risk of relapse will be enrolled using a modified 3+3 design. Upon completion of Cycle 1, subjects not experiencing dose-limiting toxicity (DLT) may continue receiving their assigned Mana 312 dose every 28 days for an additional 2 doses unless the subject experiences progressive disease (PD), exhausts their supply of Mana 312, experiences intolerable side effects, is removed by the Investigator, withdraws consent, or the study is terminated. After Cohort 1 has been completed (i.e., a decision has been made to proceed to Cohort 2), enrollment will be limited to subjects with high-risk of relapse AML/MDS (see Inclusion Criterion #4b) until the RP2D is determined). In the Expansion Cohort, only subjects with high risk of relapse AML/MDS will be enrolled using the RP2D of Mana 312. Subjects in the Expansion Cohort will receive Mana 312 at the time of relapse or at 1 year after HSCT, whichever is first. Subjects not experiencing dose-limiting toxicity (DLT) may continue receiving their assigned Mana 312 dose every 28 days for an additional 2 doses unless the subject experiences progressive disease (PD), exhausts their supply of Mana 312, experiences intolerable side effects, or the study is terminated. ;
