About this study

Official title: Sirolimus in Prevention of aGVHD in Maternally Engrafted (TME) Severe Combined Immunodeficiency (SCID) Infants Receiving Unconditioned Hematopoietic Stem Cell Transplant (HSCT)

Study Design: SCID infants receiving an unconditioned haploidentical transplant will be started on Sirolimus (0.05 mg/kg/day) day -5 for Acute Graft-Versus-Host Disease (aGVHD) prophylaxis. Sirolimus levels will be monitored with goal sirolimus trough level of 5-8 ng/mL. Patients will be monitored for signs of aGVHD as defined by UCSF SOP CL 221.06 through day +100. Sirolimus will be tapered once T-regulatory cell to CD4 effector cell ratio is > or = 9%.

Setting: Inpatient BMT Unit Benioff Children's Hospital at UCSF Medical Center

Study Subjects: 15 infants with diagnosis of maternally engrafted T cells SCID by CA Newborn screen receiving unconditioned haploidentical HSCT

Main Outcome Measures: Incidence of aGVHD (dermatitis, hepatitis, enteritis) as defined by SOP CL 221.06 by Day +100.

Hypothesis 1. Patients placed on sirolimus prophylaxis will have lower incidence of aGVHD compared to historical controls.

Hypothesis 2. Lower doses of sirolimus milligram per kilogram will be required to maintain goal troughs of 5-8 ng/mL.

What is being measured

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

  1. Incidence of aGVHD

    Incidence of aGVHD (dermatitis, hepatitis, enteritis) as defined by UCSF SOP CL 221.06 by Day +100.

    Measured: 105 days

Secondary outcomes (2)
  1. T-regulatory cell enumeration

    T-regulatory cell enumeration studies by blood draw prior to prophylaxis and at day +30, day+60, day+100.

    Measured: 105 days

  2. Sirolimus therapeutic drug monitoring

    Sirolimus therapeutic drug monitoring will be done via blood draws(after initial 4th dose; thereafter every 4th dose with adjustment; once stable it will be measured weekly). We will determine the average dose in milligrams per kilograms that would be needed to reach therapeutic trough levels of 5-8 ng/mL.

    Measured: 105 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sirolimus in people with Severe Combined Immunodeficiency and Transplacental Maternal Engraftment, run by University of California, San Francisco 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 3 inclusion and 1 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: withdrawn, as of the sponsor's last update on 3 Dec 2015. 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 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Incidence of aGVHD (time frame: 105 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02177760, which also lists 9 linked publications.

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 3 Dec 2015.
