About this study

Official title: A Study Evaluating BPX-501 T Cells and AP1903 for Prevention of Graft Versus Host Disease (GVHD) After Haploidentical, Related, T Cell-Depleted Hematopoietic Cell Transplantation for Non-Malignant Diseases

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adverse Events

    To determine the safety (as defined by non-responsive Grade III-IV GVHD to rimiducid) of HCT with HLA-haploidentical CD34+ selected peripheral blood stem cell (PBSC) grafts and BPX 501 T cells followed by scheduled rimiducid infusion on Day 7.

    this outcome measure is reported as number of patients who experienced the AE of Grade III-IV GVHD that was not non-responsive to rimiducid (safety switch) administration.

    Measured: 24 months

  2. Engraftment

    Determine the engraftment rate (defined as >50% donor CD3 chimerism) on day 28 after HCT with HLA-haploidentical CD34+ selected PBSC grafts per dose cohort of BPX 501 T cells followed by Rimiducid infusion on Day 7.

    NOTE: only one patient was enrolled who received the dose of 5x 10^6cell/kg dose of BPX-501

    Measured: Day 28

Secondary outcomes (6)
  1. GvHD

    To determine the incidence and severity of acute and chronic GVHD

    Measured: Month 24

  2. Immune Reconstitution

    Measure immune reconstitution

    Measured: Month 24

  3. Infection Rates

    Determine the risk for severe infections

    Measured: Day 200

  4. Graft Rejection

    Incidence of graft rejection

    Measured: Month 24

  5. Rimiducid Activity

    Time to resolution of acute and chronic GvHD following administration of Rimiducid

    Measured: Month 24

  6. High Grade Toxicity

    Rate of high grade toxicity

    Measured: Month 24

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BPX-501 and Rimiducid in people with Primary Immune Deficiency Disorders and Hemophagocytic Lymphohistiocytosis, run by Bellicum Pharmaceuticals at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 25 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Mar 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse Events (time frame: 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2024.
