Overview
Brief Summary
Aim of this study will evaluate the Efficacy and Safety of Anti-PD-1 monoclonal antibody Combined Lenalidomide and Azacitidine in Relapsed/Refractory Peripheral T-cell Lymphoma Patients.
Detailed Description
Peripheral T-cell lymphomas (PTCLs) are malignancies of immunologically mature T-cells that arise in peripheral lymphoid tissues. Compared with B-cell lymphoma, the treatment methods of PTCL are more limited, the first-line therapy is usually CHOP-like therapy, but the efficacy is poor, 5-year overall survival rate (OS) is only 30%-40%. Anti-PD-1 monoclonal antibody, Lenalidomide and Azacitidine can all have tumor-killing effects, and the three have complementary theoretical basis in the mechanism of action. This study will evaluate the efficacy and safety of Anti-PD-1 monoclonal antibody Combined Lenalidomide and Azacitidine in Relapsed/Refractory Peripheral T-cell Lymphoma patients.

Eligibility Criteria
Inclusion Criteria
- •Pathological immunohistochemistry or flow cytometry confirmed that R/R PTCL with measurable (diameter greater than 1.5cm) lesions meets any of the following conditions: 1\> After 4 courses of standard first-line therapy or 2 courses of more than two-line therapy, the lesions were reduced by \<50%; 2\> PTCL with disease progression after first-line or induction therapy; 3\> After hematopoietic stem cell transplantation, new lesions appear or the size of previously affected lesions increased by more than 50%.
- •Age ≥ 18 years.
- •The main organ functions need to meet the following conditions:Hemogram needs to meet HB ≥70\*1012/L，PLT≥50\*109/L，NE≥1\*109/L；LVEF≥50%;CR≤132umol/l or CCr≥60 ml/min;ALT and AST≤2 times normal range；Lung function≤Level 1;dyspnea(CTCAE v5.0),and blood oxygen saturation without oxygen absorption\> 91%.
- •Subjects of child-bearing or child-fathering potential must be willing to practice birth control from the time of enrollment on this study until the follow-up one year period of the study.
- •Estimated survival time ≥3 months.
- •Voluntary signing of informed consent.
Exclusion Criteria
- •Accepted major surgery within 4 weeks before treatment.
- •Prior malignancy (other than Relapsed/Refractory Peripheral T-cell Lymphoma), except for cured malignant tumors with no active lesions for 3 years;Adequate treatment of inactive lesions in non-melanoma skin cancer,malignant tonsilloma or carcinoma in situ;
- •Patients who have previously received failed allogeneic hematopoietic stem cell transplantation.
- •Have stroke or intracranial hemorrhage within 3 months.
- •Evidence of complications or medical conditions, including but not limited, that may interfere the conduct of the study or place the patient at serious risk:significant cardiovascular disease(class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification、myocardial infarction within 6 months of screening、uncontrolled or symptomatic arrhythmias) and/or significant lung disease.
- •HIV infection and/or active hepatitis B or active hepatitis C.
- •Uncontrolled systemic infection.
- •Pregnant or breasting-feeding women.
- •According to the researchers' judgment, any life-threatening disease, medical condition or organ system dysfunction which can endanger the patient's safety and Interfer with the absorption or metabolism of anti-PD-1 monoclonal antibody plus Lenalidomide and Azacitidine,may put the results of a study at unnecessary risk.
