About this study

Official title: Follow-Up of a Phase-I Gene Therapy Trial of Patients With Leukocyte Adherence Deficiency

This study will provide long-term monitoring of two patients who received gene therapy for leukocyte adherence deficiency (LAD) under the Food and Drug Administration investigational new drug study BB-IND-7949. The IND protocol has been closed. No other patients are eligible for this study.

Patients previously enrolled in BB-IND-7949 (Retrovirus-Mediated Transfer of the cDNA for Human CD18 into Peripheral Blood Repopulating cells of Patients with Leukocyte Adherence Deficiency) will be followed at least yearly for an indefinite period of time to evaluate their medical status and look for treatment side effects. The follow-up visits at the NIH Clinical Center will involve the following:

Read more
  • Interview regarding health status during the past year
  • Blood draw of approximately 15 milliliters for 3 years, then 5 ml annually thereafter for studies related to LAD and to make sure no unexpected effects of gene therapy have occurred

The blood samples collected at the follow-up visits will be frozen and stored. If a serious medical problem arises, the sample may be checked for replication competent virus. If the gene therapy is suspected to be related to a medical problem, investigation may include a review of the patient's medical records or collection of additional blood or tissues for testing. If the patient should die, the family will be asked permission to perform an autopsy, regardless of the cause of death. Tissues taken at autopsy will be tested for any long-term effects from the gene therapy.

Read the detailed description

Patients with leukocyte adhesion deficiency or LAD have a deficiency of the leukocyte integrin CD18 on their leukocyte cell surface and suffer from severe bacterial infections. Two patients with LAD were enrolled in a Phase I clinical trial conducted at the University of Washington School of Medicine in 1999 to determine the safety and potential efficacy of using retroviral vectors containing CD18 to transduce and correct their CD34+ peripheral blood stem cells. This protocol aims to continue the long-term follow-up of these patients at the National Cancer Institute where Dr. Hickstein is now a Senior Investigator. Blood samples will be collected at the follow-up visits on the yearly anniversary of the treatment date (either locally or off-site by the patients' personal physicians) for archiving for potential testing for replication competent retrovirus, and for complete blood counts. Patients will also undergo a history and physical examination at these visits. Results from these tests will be forwarded to the investigators who will report to the NIH and FDA.

Questions about this trial

What is this clinical trial studying?

An observational study of Leukocyte Adhesion Deficiency Syndrome, run by National Cancer Institute (NCI) at 1 site in United States.

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

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jul 2017. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00023010, which also lists 2 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 2 Jul 2017.
