For people with severe combined immune deficiency (SCID), their immune system does not work properly. The only cure for most SCIDs is stem cell transplant. These transplants can have serious complications. Researchers want to see if the drug JSP191 can help.
Objective:
To learn if the JSP191 monoclonal antibody is safe and effective for stem cell transplant conditioning for people with certain types of SCID.
Eligibility:
People ages 3 and older who have SCID and have received stem cell transplant but need a retransplant. Their original donor will provide the new sample.
Design:
Participants will be screened with:
Physical exam
Eye exam
Blood and heart tests
Scans
Bone marrow sample
Questionnaires
Participants will be admitted to the hospital. They will receive a central venous catheter if they do not have one. They will receive the JSP191 infusion through a vein. About 10-21 days later, they will have a bone marrow biopsy. Then they will have a stem cell transplant.
Participants will stay at the hospital for 30 days after transplant to recover. They must remain local to the hospital for 8 weeks after discharge for monitoring. They will have several blood tests.
After the 8 weeks, participants will have follow-up visits 1-2 times a year for 5 years. These will include repeats of the screening tests.
Donors will have visits 6 days in a row. They will be injected with a drug to help them make more stem cells. They will donate the cells via apheresis. For this, blood will be drawn and circulated through a machine over 2-6 hours.

INCLUSION CRITERIA: 1. Typical SCID as defined by Primary Immune Deficiency Treatment Consortia (1A) (Shearer, Dunn et al. 2014) (PIDTC) including but not limited to the following subtypes: a. T-, B+, NK-: IL-2Rcy deficient, JAK3-deficient b. T-, B-, NK+: RAG1/2 deficient, Artemis-deficient c. T-, B+, NK+: IL7Ralpha deficient, CD3 subunit deficient, CD45 deficient OR Variant SCID with absent or low T cell function, Omenn syndrome, Leaky SCID, Reticular dysgenesis, Adenosine deaminase deficiency, and Purine nucleoside phosphorylase deficiency may be included after consultation with the medical monitor. 2. Organ function defined as: a. Serum Creatinine < 1.5 x upper limit of normal (ULN) or 24-hour creatinine clearance >= 50 mL/min b. Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and diffusing capacity of the lung for carbon monoxide (DLCO) corrected for hemoglobin and volume, > 40% predicted by pulmonary function tests (PFTs) c. For subjects unable to cooperate for PFTs, criteria are no evidence of dyspnea at rest, no exercise intolerance, and no requirement for supplemental oxygen d. Shortening fraction of >= 27% or ejection fraction of (Bullet) 50% by echocardiogram e. Serum total bilirubin of < 2 x ULN, unless attributable to Gilbert's syndrome f. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) <= 5 x ULN g. Absolute neutrophil count > 500 per microliter of blood h. Platelet count > 100,000 per microliter of blood i.

Prior donor of appropriate age (>= 5 years old) available for re-collection of stem cells by apheresis 2. Previous allogeneic HCT (>= 6 months post initial transplant) with poor graft function defined as one of the following: a. Inadequate B cell engraftment, defined by any of the following parameters: i. Absence (< 5%) of donor B cells ii. IgA and IgM < normal values for age iii. Isohemagglutinin titer < 1:8 iv. Anti-tetanus antibody titers post-vaccination < 3 x pre-vaccination titer or below protective level off Ig replacement for 3 months OR persistent severe hypogammaglobulinemia requiring routine immunoglobulin replacement b.

These stringent donor myeloid chimerism analyses will be performed, at a central lab, on flow-cytometric sorted CD15+ myeloid cells, followed by STR PCR-based assay. Due to a potential for stringent myeloid chimerism assay (flow-cytometric sorting and PCR) variability (+/- 1%), subjects with stringent donor myeloid chimerism of 1% may be enrolled in the trial with medical monitor approval. Inclusion criteria specific to Group B: 1. Age >= 3 months SCID, without history of allogeneic HCT 2. Haploidentical donor of appropriate age (>= 5 years old) or HLA-matched non-sibling donor (8/8 at allelic level at HLA-A, -B, -C, and -DR), or HLA-matched sibling donor for subjects >= 18 months of age available for apheresis a. For NK+ SCID subjects who have transplacental maternal engraftment (TME), the mother is the preferred donor. Alternative donors may be considered after consultation with the medical monitor. b. For RAG 1/2-deficient and Artemis-deficient subjects who have TME, the mother is the preferred donor. Alternative donors may be considered after consultation with the medical monitor. c. TME is defined as evidence of maternal genotype in isolated CD3 cells analyzed by polymerase chain reaction (PCR), short-tandem-repeat (STR) analysis, or variable number tandem repeats (VNTR) based assays. EXCLUSION CRITERIA, ALL GROUPS: 1. Subjects with any acute or uncontrolled infections. Acute infection will refer to a bacterial, fungal or viral infection newly acquired within 1 month of enrollment that is uncontrolled as defined by signs and symptoms of the infection not improving or getting worse over that month. Uncontrolled infection, whether acute or chronic as an exclusion criterion will be defined as any infection of a severity or with acute progression in the month prior to enrollment that in the opinion of the PI poses an unacceptable risk to a subject undergoing conditioning and transplant. Acute infections that have resolved with or without specific treatment by the time of enrollment are not exclusions. 2. Subjects receiving any other investigational agents 3.
