Evaluating SMART101 for immune recovery in blood cancer patients after stem cell transplant

An Open-label, Multi-center Phase I/II Study to Assess the Safety and the Efficacy of SMART101 After Haploidentical Peripheral Blood Stem Transplantation With Post-transplant Cyclophosphamide in Subjects With Hematological Malignancies

Phase1; Phase2 Interventional Smart Immune SAS · NCT05768035

This study is testing a new treatment called SMART101 to see if it can help blood cancer patients recover their immune systems faster after a stem cell transplant.

What this trial studies

This clinical trial aims to assess the safety and efficacy of SMART101, a treatment involving Human T Lymphoid Progenitors (HTLP), to enhance immune recovery in adult patients with hematological malignancies following haploidentical hematopoietic stem cell transplantation (HSCT) combined with post-transplant cyclophosphamide. The study will involve administering allogeneic T cell progenitors that are cultured ex-vivo to eligible participants. The trial is designed to determine how well this intervention can support patients' immune systems during recovery after transplantation.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), or myelodysplastic syndromes (MDS) who are eligible for haploidentical HSCT.

Not a fit: Patients who have previously undergone allogeneic stem cell transplantation or those who have received other cellular therapies or investigational agents shortly before the SMART101 infusion may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve immune reconstitution and overall recovery for patients undergoing stem cell transplantation for blood cancers.

How similar studies have performed: While this approach is innovative, there is limited data on the success of similar interventions, making this study a potentially novel exploration in the field.
