简要总结

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....

详细描述

Background:

  • Relapsed or refractory T-cell lymphoma is typically incurable with a median survival of less than 1 year. Angioimmunoblastic T-cell lymphoma (AITL) is the most commonly defined subtype of T-cell lymphoma and has a similarly poor prognosis.
  • We have developed the first AITL cell lines that maintain immunophenotypic fidelity with AITL and used these cell lines to identify novel therapies for patients with AITL.
  • We found that CD28 blockade with the Food and Drug Administration (FDA)-approved rheumatologic agent abatacept, which blocks CD28 signaling, impaired the proliferation of AITL cell lines, and that injection of abatacept into patient-derived xenograft (PDX) models of AITL significantly prolonged their survival. Based on this we conclude that targeting CD28 with abatacept in AITL is a promising, novel therapeutic approach that warrants clinical testing in people with relapsed/refractory (R/R) T-cell lymphoma.
  • Abatacept can be combined with the deoxyribonucleic acid (DNA) methyltransferase inhibitor azacitidine, which has been shown to be preferentially active in patients with a TET2 mutation, the most common genetic abnormality in patients with AITL. We confirmed that azacitidine indeed inhibits AITL cell lines synergistically with abatacept.

Objectives:

  • Arm 1: To estimate the maximum tolerated dose (MTD) of the combination of azacitidine and abatacept in relapsed or refractory T-cell lymphoma.
  • Arm 2: To estimate the complete response rate (CRR) of the combination of azacitidine and abatacept.

  • ECOG performance status <=
  • 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
  • Platelets / >= 50,000 cells/mcL OR >= 25,000 cells/mcL if bone marrow involvement with lymphoma
  • Hemoglobin / >= 8 g/dL (transfusions permitted)
  • Renal function / Serum creatinine <= 2 mg/dL OR Glomerular filtration rate (GFR) >= 40 mL/min/1.73 m^2 as estimated by the Modification of Diet in Renal Disease (MDRD).
  • Note: there is no limit if involved by lymphoma.
  • If not on target, a 24-hour urine creatinine clearance can be used to directly measure creatinine clearance.
  • Total bilirubin / <= 1.5 x upper limit of normal (ULN)
  • Aspartate Aminotransferase (AST) / <= 3.0 x ULN
  • Alanine Aminotransferase (ALT) / <= 3.0 x ULN
  • Prothrombin time (PT) / <1.5 x ULN
  • Activated partial thromboplastin time (aPTT) / <1.5 x ULN; < 5.0 x ULN if the aPTT is prolonged because of a positive Lupus Anticoagulant
  • International normalized ratio (INR) / <1.5 x ULN
  • Participants, seropositive for human immunodeficiency virus (HIV), must have an undetectable HIV viral load.
  • Participants, seropositive for hepatitis C virus (HCV) infection, must have been treated and have an undetectable HCV viral load.
  • Participants who are hepatitis B core antibody (HBcAb) positive must have a hepatitis B virus (HBV) viral load result <100 IU/mL. Note: participants who are hepatitis B surface antigen (HBsAg) positive are excluded.
  • Participants with detectable Epstein-Barr virus (EBV) or Cytomegalovirus (CMV) by polymerase chain reaction will be eligible provided they do not have end organ dysfunction from EBV or CMV infection.
