Brief Summary
The purpose of this study is to determine whether bilateral orthotopic lung transplantation (BOLT) followed by cadaveric partially-matched CD3+/CD19+ depleted bone marrow transplant (BMT) is safe and effective for individuals aged 10 through 45 years with the diagnosis of primary immunodeficiency (PID) and end-stage lung disease. The enrollment goal: 8 participants who receive both BOLT and BMT.

Outcome Measures
Primary Outcomes (9)
Safety: Death
How many, if any, participants die during study participation.
Average of approximately 31 months for those who received an initial transplant
Safety: Engraftment Syndrome
How many, if any, participants develop engraftment syndrome.
Average of ~7.5 months of time post BMT for those receiving both lung and BMT transplants.
Engraftment Failure
Average of ~7.5 months of time post BMT for those receiving both lung and BMT transplants.
Grade 4 or 5 Events Potentially Attributable to Rituximab
Average of ~25 months.
BOS at 1 Year Post BOLT
Diagnosis of BOS (Bronchiolitis Obliterans Syndrome) at any time up to 1 year post BOLT. BOS is one of the undesirable complications of lung transplantation.
throughout the first year post BOLT
Efficacy: Count of Participants With Requirement for Supplemental Oxygen and/or Ventilatory Support
The number of participant(s) who need either supplemental oxygen and/or ventilator support (noninvasive/invasive) will be assessed using the Bronchiolitis Obliterans Syndrome (BOS) Classification Score for pulmonary function (e.g., the Forced Expiratory Volume in 1 Second (FEV1). FEV1 is air volume exhaled in 1 second during spirometry, a lung function test. (Continuing dependence on supplemental oxygen or ventilatory support is an undesirable outcome of lung transplantation).
at 1 Year Post Lung Transplant (BOLT)
Efficacy: Count of Participants With T-cell Chimerism
The number of participants who have ≥ 25% donor T-cell chimerism.
1 Year Post Bone Marrow Transplant (BMT)
Efficacy: Count of Participants With Myeloid Chimerism
The number of participants with myeloid disorders (e.g. Chronic Granulomatous Disease \[CGD\]) who attain ≥ 10% myeloid chimerism.
1 Year Post Bone Marrow Transplant (BMT)
Efficacy: Count of Participants B-cell Chimerism
The number of participants with B-cell disorders who attain ≥ 10% B-cell chimerism.
1 Year Post Bone Marrow Transplant (BMT)
Secondary Outcomes (12)
Count of Participants Able to Proceed to BMT
6 Months Post Lung Transplant (BOLT)
Count of Participants Who Achieve Tolerance
Average of ~7.5 months of time post BMT for those receiving both lung and BMT transplants.
Long Term Complications of Combined Solid Organ and Bone Marrow Transplant
Average of ~7.5 months of time post BMT for those receiving both lung and BMT transplants.
Count of Participants Who Develop Acute Cellular Rejection and Graft Failure
Average of ~7.5 months of time post BMT for those receiving both lung and BMT transplants.
Count of Participants Able to Initiate Withdrawal of Immunosuppression
1 year following BMT
- +7 more secondary outcomes
Study Arms (1)
CD3/CD19 neg allogeneic BMT
EXPERIMENTALParticipants may receive a double lung transplant followed by a bone marrow (hematopoietic stem cells) transplant, if a partially HLA-matched organ offer is accepted. The lungs and allogeneic hematopoietic stem cells will be from the same partially HLA-matched cadaveric donor. Prior to marrow transplantation, the marrow will be negatively selected for CD3/CD19 using a CliniMACS® depletion device.
Interventions
Negative selection for CD3/CD19 will be performed on a CliniMACS® depletion device within 36 hours of collection, and cryopreserved for later marrow transplantation. BMT conditioning and transplantation will start at least 8 weeks or more post lung transplant - once the participant is clinically judged suitable to undergo BMT conditioning and transplantion.
Eligibility Criteria
You may qualify if:
- Subject and/or parent guardian must be able to understand and provide informed consent;
- Subject fulfills criteria for United Network of Organ Sharing (UNOS) listing;
- Subject must have evidence of an underlying primary immunodeficiency for which Bone Marrow Transplant (BMT) is clinically indicated. Examples of such diseases include, but are not limited to:
- Severe Combined Immunodeficiency (SCID)
- Combined immunodeficiency with defects in T-cell-mediated immunity, including Omenn syndrome and DiGeorge Syndrome
- Severe Chronic Neutropenia
- Chronic Granulomatous Disease (CGD)
- Hyper Immunoglobulin E (IgE) Syndrome or Job's Syndrome
- CD40 or CD40L deficiency
- Wiskott-Aldrich Syndrome
- Mendelian Susceptibility to Mycobacterial Disease
- GATA2-associated Immunodeficiency.
- Subjects must have evidence of end-stage lung disease and be candidates for bilateral orthotopic lung transplant as determined by the lung transplant team;
- Glomerular filtration rate (GFR) ≥ 50 mL/min/1.73 m\^2;
- Aspartate aminotransferase (AST), Alanine aminotransaminase (ALT) ≤ 4x upper limit of normal, total bilirubin ≤ 2.5 mg/dL, normal INR;
- +16 more criteria
You may not qualify if:
- Inability or unwillingness of a participant to give written informed consent or comply with study protocol;
- Subjects who have underlying malignant conditions;
- Subjects who have non-malignant conditions that do not require hematopoietic stem cell transplantation;
- Human Immunodeficiency Virus (HIV) positive by serology or polymerase chain reaction (PCR), human T-lymphotropic virus (HTLV) positive by serology;
- Females who are pregnant or who are lactating;
- Allergy to dimethyl sulfoxide (DMSO) or any other ingredient used in the manufacturing of the stem cell product;
- Uncontrolled pulmonary infection, as determined by radiographic findings and/or significant clinical deterioration.
- Uncontrolled systemic infection, as determined by the appropriate confirmatory testing e.g. blood cultures, PCR testing, etc.;
- Recent recipient of any licensed or investigational live attenuated vaccine(s), within 4 weeks of transplant; or
- 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 participant's ability to comply with study requirements,
- or that may impact the quality or interpretation of the data obtained from the study.
