Brief Summary
Background: T-cell lymphoma is a blood cancer that affects immune system cells. People tend to survive less than 1 year if this disease does not respond to treatment (is refractory) or comes back after treatment (relapses). Azacitidine and abatacept are 2 drugs that are used to treat other diseases. Researchers want to know if these drugs, used together, can help people with T-cell lymphoma. Objective: To learn if azacitidine combined with abatacept can shrink tumors in people with T-cell lymphoma. Eligibility: People aged 18 years and older with T-cell lymphoma that either came back or did not respond to treatment. Design: Participants will be screened. They will have a physical exam with blood tests. They will have a test of their heart function. They will have imaging scans of their tumors. A sample of tumor tissue may be taken. Azacitidine is injected under the skin of the thigh, abdomen, or upper arm. Abatacept is infused through a needle inserted into a vein in the arm. Participants will receive the study drugs in 28-day cycles for up to 13 cycles. They will come to the clinic for each treatment. They will come to the clinic on day 1 and day 15 of the first cycle. After that, they will come to the clinic on the first 5 or 7 days of each cycle. Each clinic visit will take no more than 8 hours. Imaging scans and other tests will be repeated during the study. Participants will have follow-up visits for up to 5 years after they stop taking the study drugs....

Outcome Measures
Primary Outcomes (2)
Arm 2: To estimate the CRR of the combination of azacitidine and abatacept.
Complete response rate (CRR) will be evaluated in Arm 2 in participants treated at MTD. CRR will be estimated along with a 95% confidence interval (CI).
Day 1 of Cycles 1, 4, 7, 10, EOT/PD visit, every 3 months for years 1-2, every 6 months for years 3-4, once a year for year 5.
Arm 1: To estimate the MTD of the combination of azacitidine and abatacept in relapsed or refractory T-cell lymphoma.
MTD will be determined based on the DLT profile during the DLT window in Arm 1 56 days (cycles 0-1).
56 days (cycles 0-1)
Secondary Outcomes (2)
To determine the ORR defined as CR + PR to the combination of azacitidine and abatacept
Day 1 of every cycle then at the EOT/PD visit, every 3 months for years 1-2, every 6 months for years 3-4, then once a year until progression, initiation of another line of therapy, or 5 years since treatment initiation.
To determine the safety profile of a combination of azacitidine and abatacept in relapsed or refractory T-cell lymphoma
Day 1 through 30 days after the last study intervention was administered or before the initiation of a new anti-cancer treatment, whichever comes first.
Study Arms (2)
Arm 1
EXPERIMENTALEscalating/de-escalating doses of azacitidine + abatacept
Arm 2
EXPERIMENTALMTD of azacitidine + abatacept if less than 12 participants are enrolled in Arm 1
Interventions
Days 1-5 or 1-7 of every cycle (12 cycles): azacitidine subcutaneous or IV at the dose of 75 mg/m2
Cycle 0, Days 1 and 15: abatacept IV infusions at the dose of 5 mg/kg or 10 mg/kg. Cycles 1-6, Day 1: abatacept IV infusions at the dose of 5 mg/kg or 10 mg/kg.
Eligibility Criteria
You may qualify if:
- Participants must have a histologically or cytologically confirmed T-cell lymphoma confirmed by the Laboratory of Pathology (LP), NCI. The one of the following T-cell lymphomas are included:
- Peripheral T-cell lymphoma not otherwise specified (PTCL, NOS)
- Angioimmunoblastic T-cell lymphoma (AITL)
- T-follicular helper (TFH) lymphoma
- Anaplastic large cell lymphoma (ALCL)
- Enteropathy-associated T-cell lymphoma (EATL)
- Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL)
- Adult T-cell leukemia/lymphoma (ATLL)
- Other T-cell lymphoma (TCL)
- Participants must have a disease that is relapsed or refractory after initial systemic treatment.
- Participants must have evaluable disease on screening imaging or by laboratory assessment.
- Age \>= 18 years.
- ECOG performance status \<= 2.
- Participants must have adequate organ and marrow function as defined below:
- Absolute neutrophil count (ANC) / \>= 1,000 cells/mcL OR \>= 500 cells/mcL if bone marrow involvement with lymphoma
- +20 more criteria
You may not qualify if:
- Any second malignancy that requires current active systemic therapy.
- Latent tuberculosis (TB) infection.
- Active systemic bacterial, viral, fungal, mycobacterial, parasitic, or other infection requiring anti-infective treatment within 1 day prior to the study treatment initiation.
- Anti-cancer therapy within 2 weeks prior to the study treatment initiation. Note: systemic steroids are allowed if \<= 100 mg/per day of prednisone (or equivalent) and were used for \<= 7 days during 2 weeks before the study treatment initiation.
- Any investigational therapy within 2 weeks prior to the study treatment initiation.
- Known allergy or hypersensitivity to any of the study drugs.
- Pregnancy confirmed with beta-human chorionic gonadotropin (beta-HCG) serum or urine pregnancy test in WOCBP at screening.
- Active central nervous system involvement with lymphoma. Previously treated central nervous system involvement with lymphoma will be allowed if \>3 months since end of treatment.
- Uncontrolled intercurrent illness, factors, evaluated by medical history, electrocardiogram (EKG), and physical exam that would potentially increase in risk of participant.
