Brief Summary

Angioimmunoblastic T-cell lymphoma (AITL) belongs to a subtype of peripheral T-cell lymphoma (PTCL) and is also a distinct type of non-Hodgkin lymphoma (NHL). The clinical outcomes of AITL is poor and optimal treatment strategies for AITL have not been fully defined. Patients with disseminated or relapsed disease have a very poor outcome, and there is no standard management for relapsed or refractory disease. Epigenetic drugs have been widely used to treat patients with refractory/relapse AITL. Several phase II clinical trails demonstrated the ORR of 33-50% in patients with r/r AITL treated with HDAC inhibitors (including Belimastat, Romidepsin, Chidamide). HDAC inhibitors are important drugs for the current treatment of AITL, but still more than half of the patients can not benefit from it. PD1/PD-L1 blockade was a potent strategy for r/r PTCL in two small sample studies. Current studies have found that HDACi can upregulate the expression of PDL1, In vivo testing of C57BL/6 mice revealed a synergistic tumor suppression after combining HDACi and PD-1 blockade. We carried out a single, open-label, multicenter clinical trial enrolled patients with relapsed/refractory AITL to investigate the safety and efficacy of sintilimab in combination with chidamide.

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all

• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Volunteer to participate in clinical research; fully understand and know the research and sign the Informed Consent Form (ICF); willing to follow and have the ability to complete all trial procedures;
• Aged 18-75 years old male or female;
• Angioimmunoblastic T-cell lymphoma confirmed by histopathology examination;
• Paraffin tissue specimens or fresh puncture tissue specimens are available;
• Patients with refractory or relapsed angioimmunoblastic T-cell lymphoma after anthracycline-contained regimen treatment. Refractory is defined as: patients did not get partial remission (PR) or better responses after first line treatment or disease progression within 6 months of the last protocol;
• Eastern cooperative oncology group score: 0-1;
• Estimated survival ≥ 3 months;
• There must be at least one evaluate able or measurable lesion that meets the RECIL 2017 Lymphoma criteria \[evaluable lesion: 18Ffluorodeoxyglucose/ Positron Emission Tomography (18FDG/PET) examination showing increased lymph node or extranodal uptake (higher than liver) and PET and/or computed tomography (Computed Tomography) CT) features are consistent with lymphoma findings; lesions can be measured: nodular lesions \> 15mm or extranodal lesions \> 10mm (if the only measurable lesion has received radiotherapy in the past, there must be evidence of radiological progress after radiotherapy), and accompanied by increased 18FDG uptake). Except for this, there is no measurable increase in diffuse 18FDG uptake in the liver;
• Adequate organ and bone marrow function, no severe hematopoietic dysfunction, cardiac, pulmonary, liver, kidney, thyroid dysfunction and immune deficiency (no blood transfusion, granulocyte colony stimulating factor or other medical support was received within 14 days prior to the use of the research drug): 1) The absolute value of neutrophils (\>1.0×10\^9/L); 2) platelet count (\> 75×10\^9/L); 3) Hemoglobin (\> 9 g/ dL); 4) Upper Limit Normal (ULN) or creatinine clearance rate (\>40 mL/ min) of serum creatinine (\<1.5 times normal value upper limit) (estimated by Cockcroft-Gault formula); 5) Serum total bilirubin \< 1.5 times ULN; 6) Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) = 2.5 times ULN; 7) Coagulation function: International Normalized Ratio (INR) = 1.5 times ULN; Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT) = 1.5 times ULN (unless the subject is receiving anticoagulant therapy and PT and APTT are using anticoagulant therapy at screening time). Within the expected range; 8) Thyrotropin (TSH) or free thyroxine (FT4) or free triiodothyronine (FT3) were all within the normal range (+10%);
• There was no evidence that subjects had difficulty breathing at rest, and the measured value of pulse oximetry at rest was more than 92%;
• Participants must pass a pulmonary function test (PFT) to confirm that forced expiratory volume (FEV1)/forced vital capacity (FVC) in the first second is more than 60%, unless it is a large mediastinal mass caused by lymphoma that cannot meet this standard; carbon monoxide diffusion (DLCO), FEV1 and FVC are all above 50% of the predicted value; all PFT results must be obtained within four weeks before the first administration;
• Subjects who have received antineoplastic therapy should be admitted to the group only after the toxicity of the previous treatment has returned to the level of Common Terminology Criteria for Adverse Events (CTCAE) V5.0 grade score \< 1 or baseline level; the level 2 toxicity caused by previous antineoplastic treatment is irreversible and is not expected to deteriorate during the study period. (e.g. thrombocytopenia, anemia, neurotoxicity, alopecia and hearing loss) can be enrolled with the consent of the researchers;
• Women of Childbearing Potential (WOBCP) must undergo a serum pregnancy test within seven days before the first medication and the results are negative.

• Begin the study on subjects requiring systemic glucocorticoid therapy or other immunosuppressive therapy for a given condition within 14 days before treatment \[allowing subjects to use local, ocular, intra-articular, intranasal and inhaled glucocorticoid therapy (with very low systemic absorption); and allowing short-term (\< 7 days) glucocorticoid prophylaxis (e.g., contrast agent overdose) Sensitivity) or for the treatment of non-autoimmune diseases (e.g. delayed hypersensitivity caused by contact allergens);
