About
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.
Full description
The primary purpose of this study is to evaluate the safety and efficacy of performing bilateral orthotopic lung transplantation (BOLT) followed by cadaveric, partially HLA-matched CD3+/CD19+-depleted hematopoietic stem cell transplantation (HSCT) from the same donor for participants with primary immunodeficiency diseases (PID) and end-stage lung disease. For many patients with primary immunodeficiencies, HSCT, which we refer to as Bone Marrow Transplant (BMT) is a curative, life-saving therapy, resulting in restoration of function in the immune system. Patients with primary immunodeficiencies often develop pulmonary complications as a result of chronic or recurrent infections, making them ineligible for BMT due to the high risk of mortality and pulmonary complications. Lung transplant prior to BMT would allow for restoration of pulmonary function prior to BMT, allowing PID patients to proceed to BMT , which would be curative for the patient's underlying immunodeficiency. As a secondary aim, after successful engraftment with donor bone marrow, the feasibility of participants tolerating planned withdrawal of immunosuppression and achieving eventual freedom from all immunosuppressive drugs and attaining a tolerant state will be assessed.
This is a single center study in which participants receive a cadaveric, partially Human Leukocyte Antigen (HLA)-matched lung transplant followed by a CD3+/CD19+ depleted bone marrow transplant (BMT) from the same donor. In this study, the investigators will use a ≥ 2/6 HLA-matched T cell depleted bone marrow transplant from a cadaveric organ donor with an identical ABO blood type as the recipient.
Participants will undergo:
The duration of participant involvement in the trial is up to 2 years post-BMT.

Inclusion criteria
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:

Cardiac ejection fraction ≥ 40% or shortening fraction ≥ 26%;
Negative pregnancy test for females >10 years old or who have reached menarche, unless surgically sterilized;
All females of childbearing potential and sexually active males must agree to use a Food and Drug Administration (FDA) approved method of birth control for up to 24 months after BMT or for as long as they are taking any medication that may harm a pregnancy, an unborn child or may cause birth defect; and
Subject and/or parent guardian will also be counseled regarding the potential risks of infertility following BMT and advised to discuss sperm banking or oocyte
Eligibility for Bone Marrow Transplant*:
GFR >50 mL/min/1.73 m^2;
AST, ALT <4x upper limit of normal, Total bilirubin < 2.5 mg/dL;
Cardiac ejection fraction ≥40% or shortening fraction of at least 26%;
Human Immunodeficiency Virus (HIV) negative by serology and PCR;
Human T-lymphotropic virus (HTLV) serology negative;
Forced vital capacity (FVC) and Forced expiratory volume (FEV1) ≥ 40% predicted for age and SpO2 of >90% at rest on room air AND with clearance by the lung transplant team;
Absence of uncontrolled infection as determined by blood cultures and radiographic results of previously affected sites, in particular, pulmonary densities during the past 2 weeks prior to chemotherapy;
Absence of Acute Cellular Rejection (ACR); and
Bone marrow processing has been completed, and an appropriate stem cell product is available for administration.
Exclusion criteria
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.
-- Pulmonary colonization with multiple organisms is common, and will not be considered an exclusion criterion.
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:
