Long Term Follow Up Of Patients Who Have Received Gene Therapy Or Gene Marked Products

Study Overview
=================
Brief Summary
-----------------
This protocol (GENEFU) provides a mechanism for the 15-year followup period that the FDA requires for all participants in gene transfer protocols and assures that adequate followup can be maintained for a wide variety of participants on different individual gene therapy protocols at St. Jude Children's Research Hospital. GENEFU serves as an umbrella protocol for long-term follow-up (LTFU) for recipients of gene therapy/gene marked (GT/GM) products at St. Jude Children's Research Hospital. The FDA has recommended methods to assess the risk of delayed adverse events after GT/GM and has provided specific requirements regarding the duration and design of LTFU observations. This protocol is intended to provide LTFU in accordance with the FDA guidelines for those who received a GT/GM product as part of a St. Jude-sponsored clinical trial or compassionate use treatment plan. The protocol calls for a physical examination or general health evaluation and collection of required blood samples annually for up to 15 years after the last receipt of a GT/GM product. Goals will be to obtain clinical histories in order to detect late clinical outcomes suggestive of retroviral or lentiviral disease, including but not limited to cancer/second malignancies, neurologic disorders, autoimmune disorders, and hematologic disorders. Blood samples will be archived and tested when clinically or scientifically indicated, as in the event of development of a second malignancy. This prospective cohort study will utilize descriptive statistics in the analysis of long-term late effects outcomes. It offers a uniform approach to long-term safety monitoring in research participants who have received a gene-transduced product as part of St. Jude-sponsored GT or GM protocols and compassionate use treatment plans.

Detailed Description
-----------------
Secondary objectives include the following: to obtain and archive blood samples to 1) detect frequency of vector marking in peripheral blood mononuclear cells when clinically or scientifically indicated, such as in the event of participant development of second malignancy, autoimmune disease, hematologic abnormality, or neurologic event, and; 2) To obtain and archive blood samples to detect and characterize clonal proliferation events occurring in gene transfer trials when clinically or scientifically indicated.
