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.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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.
