Study summary

The objective of this study is to make T-cell depleted stem cells from a family member who is a half match (haplo-identical) available on an expanded access basis to patients receiving one or two unrelated cord blood transplants who are at a higher risk of not engrafting in a safe amount of time. The purpose of the related stem cells is to give the bone marrow a "jump start" towards recovery. Ultimately, the cord blood cells will grow and permanently rescue the bone marrow.

Read the detailed description

The primary purpose of the study is to provide expanded access of T-cell depleted haplo-identical stem cells for patients receiving allogeneic transplantation from a related haplo-identical donor and an unrelated, umbilical cord blood (UUCB) unit(s) for the treatment of high risk malignancies and non-malignant disorders. The T-cell depleted haplo-identical stems cells are intended to facilitate early, short-term myeloid engraftment with the primary goal of minimizing early infections and other non-relapse mortality while the UUCB cells engraft as the durable and permanent graft. Patients with high risk or refractory malignancies, or non-malignant disorders amenable to stem cell transplantation therapy but lacking conventional related or unrelated donors will be eligible for this protocol.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Have a consenting related haplo-identical (3/6, 4/6, or 5/6 if DRB1 mismatch) stem cell donor.
  • Have one or two available 4, 5, or 6/6 antigen matching unrelated UCB unit(s) that will deliver a total cell dose >3.0 x 10e7 cells/kg. Patients who do not have a single UCB unit that will deliver the minimum required cell dose, two partially HLA-matched UCB units which together meet the minimum cell dose requirement, can be used for 1 transplant. These units must be HLA-matched minimally at 4 of 6 HLA-A and B (at intermediate resolution by molecular typing) and DRB1 (at high resolution by molecular typing) loci with the patient, and HLA-matched at 3 of 6 HLA- A, B, DRB1 loci with each other (using same resolution of HLA typing as indicated above). There is no limitation on maximum cell dose.
  • Have a high risk or , or non-malignant disorder amenable to stem cell transplantation therapy.
  • Meet eligibility requirements for transplant per institutional standard practices.
  • Have given written according to FDA guidelines (or consent of parent/legal guardian as applicable).
  • Be \<65 years of age at the time of study enrollment.

Exclusion criteria

Exclusion Criteria:

  • Have a consenting 8/8 or 10/10 allele matched, consenting, related or unrelated hematopoietic stem cell transplant () donor.
  • Have a of less than 3 months.
  • Have uncontrolled infections at time of cytoreduction.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
