Clinical Trial Goal
To find out:
- The highest dose of TSC-100 and TSC-101 that's safe to give after haploidentical BMT
- If TSC-100 and TSC-101 after a haploidentical BMT is safe and works well to treat ALL, AML or MDS
You may be able to join this trial if you:
- Are 18 years old or older
- Have ALL, AML or MDS
- Have a family member who is your half match and can be your donor. Your biological parents and children are always a half-match for you.
- Plan to have a haploidentical BMT
- Have not had an allogeneic (cells from a donor) BMT before
- Agree to have other standard tests done to see if you can be in the clinical trial
Trial Details
TSC-100 and TSC-101 are T cells, a type of immune cell, from a donor that have been treated to target HA-1 and HA-2, respectively.
Depending on your Human Leukocyte Antigen (HLA) type, you'll be put in 1 of 3 groups:
- Group 1: TSC-100
- Group 2: TSC-101
- Group 3: Standard care
Before transplant, you’ll get standard reduced-intensity treatment to prepare your body to receive the donated blood-forming cells.
Then, on transplant day, the blood-forming cells from your donor are given to you through an intravenous (IV) infusion.
You'll also get standard treatment to prevent graft-versus-host disease (GVHD).
If you're in Group 1 or Group 2 you'll get:
- TSC-100 – Group 1 only - Given as IV infusions. The dose you'll get depends on when you start the trial and how safe it has been
- TSC-101 – Group 2 only - Given as IV infusions. The dose you'll get depends on when you start the trial and how safe it has been
You'll have biopsies and/or scans to see how well the treatment is working. The clinical trial doctors will check your health for up to 2 years.
The Food and Drug Administration (FDA) has not yet approved TSC-100 or TSC-101. The FDA has approved all of the other drugs used in this trial.
