Hematopoietic Stem Cell Transplantation (HSCT) for Common Variable Immunodeficiency (CVID) and Other Autoimmune Manifestations of Primary Immune Regulatory Disorders (PIRD)

Summary

This is a research protocol that will examine Hematopoietic Stem Cell Transplantation (HSCT) using a reduced conditioning regimen (RIC) with total body Irradiation (TBI) in those diagnosed with Common Variable Immunodeficiency (CVID) and Other Autoimmune Manifestations of Primary Immune Regulatory Disorders (PIRD).

Eligibility

Inclusion Criteria:

1. Patient, parent, or legal guardian must have given written informed consent. For pediatric subjects who are developmentally able, assent or affirmation will be obtained.
2. Male or female, 5 through 40 years old, inclusive, at the time of informed consent.
3. Patients must have evidence of common variable immunodeficiency (CVID) or other autoimmune manifestation of a primary immune regulatory disorder (PIRD). Genetic screening is required by a targeting gene panel to determine presence of genetic variations that may lead to inborn errors of immunity.

   Examples of such diseases include, but are not limited to:
   * Common variable immunodeficiency (CVID)
   * Combined Immunodeficiency (CID)
   * Immune dysregulation polyendocrinopathy enteropathy X-linked (IPEX syndrome), IPEX like syndromes
   * Combined immunodeficiency with defects in T-cell-mediated immunity, including Omenn syndrome and DiGeorge Syndrome
   * Chronic Granulomatous Disease (CGD)
   * Signal Transducer and Activator of Transcription (STAT 1) Gain of Function (STAT1 GOF)
   * Signal Transducer and Activator of Transcription (STAT 3) Gain of Function (STAT3 GOF)
   * Hypomorphic Recombination-Activating Genes (RAG) 1 and RAG 2
   * CD40 or CD40L deficiency
   * Mendelian Susceptibility to Mycobacterial Disease
   * GATA-binding factor 2 (GATA2) Associated Immunodeficiency
   * Mouth and Genital Ulcers with Inflamed Cartilage Syndrome (MAGIC)
4. Must have previously failed, due to lack of response or intolerance, mycophenolate mofetil and a B cell-depleting antibody, such as Rituximab
5. Glomerular Filtration Rate (GFR) ≥50 mL/min/1.73 m2
6. Aspartate Aminotransferase (AST) ≤4x upper limit of normal
7. Alanine Aminotransferase (ALT) ≤4x upper limit of normal
8. Direct bilirubin ≤ 2.5 mg/dL
9. Human Immunodeficiency Virus (HIV) negative by serology and PCR
10. Human T-cell Lymphotropic Virus (HTLV) negative by serology
11. Cardiac ejection fraction ≥ 40% or shortening fraction ≥26%
12. Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) ≥40% predicted for age
13. Peripheral Capillary Oxygen Saturation (SpO2) of \>92% at rest on room air
14. Subjects must be a minimum of 8 weeks post-solid organ transplant prior to start of conditioning, if applicable
15. Negative pregnancy test for females \>10 years old or who have reached menarche, unless surgically sterilized.
16. All females of childbearing potential and sexually active males must agree to use a FDA approved method of birth control for up to 12 months after stem cell transplant or for as long as they are taking any medication that may harm a pregnancy, an unborn child or may cause birth defects.
17. Subject and/or parent guardian informed of the potential risks of infertility following stem cell transplant and advised to discuss sperm banking or oocyte harvesting.
18. Transplant endorsement from clinical immunologist

Exclusion Criteria:

1. Allergy to Dimethylsulfoxide (DMSO) or any other ingredient used in the manufacturing of the stem cell product
2. Uncontrolled systemic infection, as determined by the appropriate confirmatory testing e.g. blood cultures, Polymerase chain reaction (PCR) testing, etc.
3. Recent recipient of any licensed or investigational live attenuated vaccine(s) within 4 weeks of stem cell transplant
4. Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the subject's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study.
