Study summary

The purpose of this study is to determine a safe dose of BPX-501 gene modified T cells infused after a haplo-identical stem cell transplant to facilitate engraftment and the safety of Rimiducid (AP1903) on day 7 to prevent GVHD.

Read the detailed description

This is a single arm dose finding study evaluating the safety and efficacy of a BPX 501 infusion (T cells genetically modified with the inducible Caspase 9 suicide gene) of 3x10E6 to 1X10E7 cells/kg followed by a Rimiducid infusion on day 7 after a partially mismatched, related, T cell-depleted hematopoietic cell transplantation (HCT) in patients with non-malignant diseases. The purpose of this clinical trial is to determine the dose of BPX 501 T cell infusion with subsequent planned infusion of Rimiducid which can facilitate engraftment and prevent the occurrence of GVHD.

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

  1. Patient must meet eligibility criteria for transplantation
  2. Lack of suitable conventional donor (10/10 allele matched related or unrelated donor) or presence of rapidly progressive disease not permitting time to identify an unrelated donor
  3. Males or females
  4. Age \< 55 years old and > 4 months
  5. Diagnosis of a nonmalignant disorder considered treatable by HCT.
  6. HLA typing will be performed at high resolution (allele level) for the HLA-A, -B, Cw, DRBl, and DQB1 loci.

    i. A minimum match of 5/10 is required. ii. The donor and recipient must be identical, as determined by high resolution typing, in at least one allele of each of the following

  7. If capable of reproduction, patient must agree to use or abstinence to prevent pregnancy during the first year of enrollment and treatment.
  8. signed by patient (if ≥18 years old) or parent/guardian (if \<18 years old).
  9. Fanconi anemia patients ONLY i) Patients must meet one of the following criteria to be eligible for this study:

    1. Any patient with Fanconi anemia and bone marrow failure involving 2 of the following 3 lineages: granulocyte count \<0.5 x 109/L, count \<20 x 109/L, or \<8 g/dL.
    2. Any patient with Fanconi anemia who requires red blood cell or platelet transfusions because of marrow failure

Exclusion criteria

Exclusion Criteria:

  1. Serious organ dysfunction

  6. Patients with Fanconi anemia with AML/MDS.
Terms in these criteria, in plain language(6)

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 25, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
