Phase I, First in Human, Open Label Study to Evaluate Safety and Tolerability of TRX103 Cells in Subjects With Hematological Malignancies Undergoing HLA-mismatched Related or Unrelated Hematopoietic Stem Cell Transplantation (HSCT) TRX-103

What's the purpose of this trial?

The purpose of this Phase 1, first in human open-label study is to assess the safety and tolerability of TRX-103 in patients with hematological malignancies undergoing HLA-mismatched related or unrelated hematopoietic stem cell transplantation (HSCT). It is anticipated that up to 36 Subjects will be enrolled during a 18-24 month enrollment period. TRX-103 will be infused one time post HSCT.

This trial is currently open and accepting patients.
