About this study

Official title: Cd45 (Yth-24 and Yth 54) and Cd52 (Campath-1H) Monoclonal Antibody Conditioning Regimen for Allogeneic Donor Stem Cell Transplantation of Patients With Fanconi Anemia

The purpose of this study is to discover whether children and adults with Fanconi anemia (FA) can be safely and effectively transplanted with Human Leukocyte Antigen (HLA) mismatched (up to one haplotype), HLA-matched sibling, or unrelated donor stem cells, when leukocytolytic monoclonal antibodies are the sole conditioning agents (patients receiving an HLA mismatched transplant will receive Fludarabine as part of the conditioning regimen). Three monoclonal antibodies (MAb) will be used in combination. Two of them, YTH 24 and YTH 54 are rat antibodies directed against two contiguous epitopes on the CD45 (common leucocyte) antigen. They have been safely administered as part of the conditioning regimen for 12 patients receiving allografts (HLA matched and mismatched) at this center. They produce a transient depletion of >90% circulating leucocytes. The third MAb is Campath 1H, a humanized rat anti-CD52 MAb. This MAb has been widely used to treat B cell chronic lymphocytic leukemia (B-CLL) and more recently has been safely given at this and other centers as part of a sub-ablative conditioning regimen to patients with malignant disease. Because these MAb produce both profound immunosuppression and significant, though transient, myelodestruction we believe they may be useful as the sole conditioning regimen in patients with Fanconi anemia, in whom the use of conventional chemotherapeutic agents for conditioning produces a high rate of short and long term toxicity. We anticipate MAb mediated subablative conditioning will permit engraftment in a high percentage of these patients with little or no immediate or long term toxicity. Campath IH persists in vivo for several days after administration and so will be present over the transplant period to deplete donor T cells as partial graft versus host disease (GvHD) prophylaxis. Additional GvHD prophylaxis will be provided by administration of the medication FK506.

Read the detailed description

If clinically feasible (no aplasia, no active malignancy), the recipients marrow will be harvested and cryopreserved as a back up for use if non-engraftment/rejection is followed by failure to undergo autologous reconstitution.

For HLA Mismatched donors, harvested peripheral blood stem cells will be enriched for CD34 cells using the Clinimacs CD34 Reagent system.

Fludarabine will be given as 5 daily intravenous infusions. Campath-1H will be given as 3 daily intravenous infusions and will be followed by Anti-CD45 which will be given as four daily intravenous infusions that will be completed two days prior to stem cell infusion. Diphenydramine will be administered intravenously every 4 hours during the period of the course of each infusion.

Day -8 Campath 1H as per CAGT SOP Fludarabine 30 mg/m2 -7 Campath 1H as per CAGT SOP Fludarabine 30 mg/m2 -6 Campath 1H as per CAGT SOP Fludarabine 30 mg/m2 -5 YTH 24/54 400ug/kg over 6 hr Fludarabine 30 mg/m2 -4 YTH 24/54 400ug/kg over 6 hr Fludarabine 30 mg/m2 -3 YTH 24/54 400ug/kg over 6 hr -2 YTH 24/54 400ug/kg over 6 hr -1 -0 Stem Cell Infusion

GVHD prophylaxis will be achieved through positive selection for CD34 resulting in > 3 log T cell depletion. Previous reports have indicated that there is a low frequency of severe (Grade II/IV) GvHD after haploidentical transplants if recipients receive stem cell populations containing <5 x 10e4 CD3 positive T cells. We hope to achieve such levels with our CD34 enrichment protocol. However, pharmacologic prophylaxis will be added if the CD34 selected product contains more than 5 x 10e4 CD3+ve T cells/kg recipient weight. In addition, Campath 1H persists in the recipient circulation through the immediate transplant period and will contribute anti-GVHD activity, in vivo.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CAMPATH-1H, Anti-CD45 and Fludarabine in people with Fanconi Anemia and Severe Aplastic Anemia, run by Baylor College of Medicine at 2 sites 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 7 inclusion and 7 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 24 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 9 Aug 2012). 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?

Number of Patients With Donor Engraftment (time frame: 100 Days). 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 24 May 2018.
