Natural History Study of SCID Disorders

A Prospective Natural History Study of Diagnosis, Treatment and Outcomes of Children With SCID Disorders (RDCRN PIDTC-6901)

This study is a prospective evaluation of children with Severe Combined Immune Deficiency (SCID) who are treated under a variety of protocols used by participating institutions. In order to determine the patient, recipient and transplant-related variables that are most important in determining outcome, study investigators will uniformly collect pre-, post- and peri-transplant (or other treatment) information on all children enrolled into this study.

Children will be divided into three strata:

• Stratum A: Typical SCID with virtual absence of autologous T cells and poor T cell function
• Stratum B: Atypical SCID (leaky SCID, Omenn syndrome and reticular dysgenesis with limited T cell diversity or number and reduced function), and
• Stratum C: ADA deficient SCID and XSCID patients receiving alternative therapy including PEG-ADA ERT or gene therapy.

Each Group/Cohort Stratum will be analyzed separately.

Study Overview

• Status: Enrolling by invitation
• Conditions: Omenn Syndrome; Reticular Dysgenesis; Severe Combined Immunodeficiency (SCID); XSCID; Leaky SCID; ADA SCID

Detailed Description

This study follows participants with SCID prospectively, meaning the study enrolls participants where there is a plan to receive a blood and marrow transplant, enzyme therapy, or gene therapy in the future. Participants are then followed according to a schedule set out by the study protocol after the procedure. There are no experimental therapies on this study.

The goal of this study is to learn more about: (1) outcomes from the treatment of SCID in the modern era of medicine (2) what factors lead to the best long-term outcomes, such as best donor, conditioning regimen, timing of transplant, etc., and (3) what impact newborn screening and the early diagnosis of SCID has had on the long-term outcomes following BMT or gene therapy. Information is also being gathered on how and when the immune system recovers after bone marrow transplant (BMT), quality of life for long-term survivors, and about whether children develop normally after treatment.

This natural history study is the largest coordinated prospective study of participants with SCID ever performed. Information that investigators will learn, both now and in the future, will help doctors and other health professionals to better treat children with SCID.

Infant Neurocognitive Development By Stratum Measured by Bayley's Scales for Infant Development 3rd edition (BSID-III-R)	Infant development as measured by Bayley's scales for infant development 3rd edition (BSID-III-R, Bayley, 2006).] The BSID III-R is a standardized developmental exam that is normalized to the age of the child in months. The mean adjusted score is 100 with a standard deviation of 15 (higher being better). Evaluation conducted as per standard of care in participants ≤30 months of age.	Baseline (Pre-SCID Treatment-HCT, ERT or GT),Year 1, Year 2, Year 4, Year 5 and Year 8 Post-SCID Treatment
Neurocognitive Development By Stratum Measured by Vineland Adaptive Behavior Scales, Second Edition (Vineland II)	The Vineland II measures the personal and social skills of individuals from birth through adulthood. Since adaptive behavior refers to an individual's typical performance of the day-to-day activities required for personal and social sufficiency, these scales assess what a person actually does, rather than what he or she is able to do. Summary: The Vineland II is a measure of adaptive behavior in children, adolescents and adults. It yields an overall standard score (Adaptive Behavior Composite, ABC) and age standard scores in four domains: Communication, Daily Living Skills, Motor Skills, and Maladaptive Behaviour Index. ABC scores have a mean of 100 and a standard deviation of 15 (range = 20 to 160). Higher scores suggest a higher level of adaptive functioning. A rise in standard scores from Baseline indicates improvement. Evaluation as per standard of care.	Baseline (Pre-SCID Treatment-HCT, ERT or GT),Year 1, Year 2, Year 4, Year 5 and Year 8 Post-SCID Treatment
Neurocognitive Development By Stratum Measured by Wechsler Preschool and Primary Intelligence Scale of Intelligence, Third Edition (WPPSI III)	Cognitive ability assessed using the WPPSI III. The WPPSI-III has been developed and standardized for children ages 2 years, 6 months through 7 years, 3 months of age. The WPPSI-III yields a Verbal Score, a Performance Score, a General Language Score, and a Full Scale Score. These scores have a mean of 100 and a standard deviation of 15. The range of possible values is 50 (worst value) to 150 (best value). Evaluation as per standard of care.	Baseline (Pre-SCID Treatment-HCT, ERT or GT),Year 1, Year 2, Year 4, Year 5 and Year 8 Post-SCID Treatment
Neurocognitive Assessment by Stratum Using the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV)	The WISC-IV is designed for children 6 years 0 months to 16 years 11 months. The Full Scale IQ, ranges from 45 to 155 with a mean of 100 and standard deviation of 15. Higher scores indicate stronger cognitive function. Scores between 90 and 110 are considered to be within the range of average IQ. Evaluation in accordance with standard of care, participant ages 6 years and above.	Baseline (Pre-SCID Treatment-HCT, ERT or GT),Year 1, Year 2, Year 4, Year 5 and Year 8 Post-SCID Treatment
Incidence of Complications of HCT Requiring Treatment	Occurrence of health event(s) classified as an HCT treatment complication, including but not limited to: Veno-occlusive disease; Thrombotic thrombocytopenic purpura; Bronchiolitis obliterans / chronic lung disease; Seizures; Hypertension Outcome analysis restricted to participants with hematopoietic (stem) cell transplantation (HCT) intervention.	From HCT to Month 6, Year 1,Year 2, Year 5 and Year 8 Post-HCT
Comparison of Quality of Life (QOL) By Stratum Prior to and After SCID Treatment: Scores for Pediatric Quality of Life Questionnaire (Peds-QL)	The Peds-QL is a generic Health-Related Quality of Life (HR QoL) instrument designed specifically for a pediatric population. It captures the following domains: general health/activities, feelings/emotional, social functioning, school functioning. Higher scores indicate better quality of life (QOL) for all domains of the Peds-QL. This modular instrument uses a 5-point scale: from 0 (never) to 4 (almost always). Items are reversed scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, 4=0. 4 dimensions (physical, emotional, social, & school functioning) are scored.	Baseline (Pre-SCID Treatment-HCT, ERT or GT) to Year 1, Year 2, Year 4, Year 5 and Year 8 Post-SCID Treatment
