Detailed Description
This is an open label, phase I study of norovirus-specific T-cell immunotherapy for treatment of participants with primary immunodeficiency disorders (PID) and chronic norovirus. This study is designed to assess the safety of norovirus-specific T-cell (NST) infusion in this population. There are two arms in this study:
- Arm A: Participants who receive donor derived NST therapy after HSCT
Arm B: Participants who receive partially HLA matched NSTs. The following participants apply:
- Participants with PID who have not undergone HSCT
- Participants who undergo HSCT but do not have available donor derived NSTs
- Participants who have donors from whom NSTs cannot be generated due to norovirus seronegativity Participants will be monitored for infusion-related reactions and GVHD for 1 year following first infusion. During this time, participants will be accessed with regard to the length and quantity of norovirus shedding in stool, and gastrointestinal and constitutional symptoms will be scored by clinicians and participants. Correlative studies of T-cell immune reconstitution against norovirus, norovirus genomic sequences, and composition of the fecal microbiome will also be accessed.
The primary purpose of this phase I study is to assess the safety of administering donor-derived or partially HLA-matched NSTs in immunocompromised participants with chronic norovirus infections. Related and unrelated donors of participants who have chronic norovirus infection after HSCT will be enrolled for screening and production of NSTs from peripheral blood. Following product manufacturing, participants who have undergone HSCT (Arm A) will receive donor-derived NSTs. For participants with PID who have not undergone HSCT (Arm B), high-resolution HLA typing of the participant will be utilized for an inquiry of the NST bank to determine if a partially HLA-matched NST product exists that has antiviral activity mediated through one or more shared HLA alleles. Participants who have undergone HSCT but either do not have available donors for NST generation, or who have donors from whom NSTs cannot be generated due to norovirus seronegativity will also be eligible for inquiry for treatment with partially HLA-matched NSTs if available under study Arm B.
This will be a dose escalation study with two arms. Participants who have undergone HSCT will be enrolled on Arm A and receive NSTs derived from their HSCT donor. Participants with a diagnosis of PID who have not undergone HSCT, or participants who have undergone HSCT but do not have available donor-derived NSTs will be enrolled on Arm B and receive partially-HLA matched NSTs. Investigators will test three doses: 1 x 10^7 /m^2, 2 x 10^7 /m^2, and 4 x 10^7 /m^2. Investigators will have a 45-day safety monitoring period for immediate toxicities following infusion.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
Participant Inclusion Criteria for NST Infusion:
Participants must meet one of the following criteria:

a. Treatment with enteral topical steroids such as Budesonide at standard doses may be continued if previously utilized, but should not be newly initiated in the 3 months after NST therapy.
For participants who have undergone HSCT, participants must have stable donor chimerism at the time of NST infusion.
a. Stability will be defined as i. >95% donor chimerism in CD33 and/or whole blood chimerism OR ii. >90% donor chimerism with <5% change between subsequent tests separated by at least 1 week.

Donor Inclusion Criteria:
- Donors who have fulfilled eligibility as per FDA regulations outlined in 21 CFR 1271 subpart C. This includes that donors have been deemed in good health by donor physician based on physical examination and laboratory testing. If a donor has been chosen for the transplant based on urgent medical need that same donor will also be used for NST generation provided that there are no new reasons for ineligibility since the stem cell collection.

Exclusion Criteria:
Participants Exclusion Criteria for NST Infusion:
Participants receiving biological or immunosuppressive monoclonal antibodies targeting T-cells within 28 days prior to NST infusion, including ATG, Alemtuzumab, Basiliximab, Tociluzimab, Brentuximab, or other medications under this category as determined by the investigators.
a. If alemtuzumab has been received within 6 weeks prior to NST infusion, plasma levels should be obtained to ensure drug clearance (≤0.16 pg/ml).

Uncontrolled infections are defined as bacterial, fungal, or non-targeted viral infections with either clinical signs of worsening despite standard therapy, or chronic gastrointestinal symptoms that may be attributed to the uncontrolled infection. Progressing infection is defined as hemodynamic instability, worsening physical signs, or radiographic findings attributable to infection. Persisting fever without other signs or symptoms will not be interpreted as progressing infection.
- For bacterial infections, participants must be receiving definitive therapy and have no signs of progressing infection within 7 days prior to NST infusion and or no chronic gastrointestinal symptoms associated with this bacterial infection.

Stool viral testing for rotavirus and adenovirus via antigen or PCR testing iii. Stool bacterial culture iv. C. difficile toxin PCR b. Determination of active infection versus chronic carriage / shedding will be made by the investigators and clinical providers, and will depend on the presence of clinical symptoms corresponding with the timing of positive test results, presence of a clinical response to targeted therapy, and by histological or other testing if clinically indicated.
Participants with active and uncontrolled relapse of malignancy (if applicable).
- Failure of primary engraftment is defined as failure to achieve platelet and/or neutrophil engraftment (ANC< 500/ul and/or platelets <20 K/ul) following HSCT.
