Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
New patients will not be treated under protocol 90-HG-0195 as new and improved vectors and technologies have become available in the recent years. New patients with ADA deficiency, however, may be enrolled in protocol 90-HG-0195 for clinical evaluation of their immune system and pre-treatment testing of transduction procedures.
