Inclusion criteria

Aged 18 years or older, male or female;
Histologically confirmed relapsed or refractory PTCL patients who had received systemic treatment at least once but had failed to; Relapsed / refractory is defined as follows:

Relapsed: patients who have new lesions at the primary site or other sites after reaching CR in the previous treatment; Refractory: patients who fail to reach PR in 2 cycles or CR in 4 cycles after first-line or above systemic treatment; if the best effect or end cause is PD, the number of cycles is not required;

Life expectancy≥3 months;
Agree to provide archived tumor tissue samples or fresh tissue samples, including enough samples to complete PD-L1 test;
Computed tomography (ct) scans should show the presence of at least one of two vertical orientations; The tumor lesions that could be measured were defined, with the longest diameter of intranode lesion > 1.5cm, the shortest diameter of intranode lesion > 1.0cm and the longest diameter of extranode lesion > 1.0cm;
The functions of important organs meet the following requirements (drugs with any blood component and cell growth factor are not allowed to be used within 14 days before the first administration):

routine blood tests: hemoglobin ≥ 90 g/L, neutrophil ≥ 1.5 ×109/L, platelet ≥ 75×109/L; Total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 times the upper limit of normal (ULN); If there is liver metastasis, TBIL ≤ 3 × ULN, ALT and AST ≤ 5 × ULN; Serum creatinine ≤ 1.5×ULN; Thyroid function indicators: thyroid-stimulating hormone (TSH) are within the normal range or thyroid-stimulating hormone (TSH) are not within the normal range and free thyroxine (FT3/FT4) are within the normal range;
