Arm && Interventions

Group	Intervention	Description
Chidamide Tablets combined with AK112	Chidamide Tablets combined with AK112	1. Medication dosage：Chidamide Tablets（30mg,Twice a week，po），AK112（Once every 3 weeks）. If you experience any discomfort during the medication process, please inform your responsible doctor in a timely manner. He/she will provide appropriate treatment based on the severity of the reaction. In severe cases, the dosage of medication will be adjusted until it is stopped. 2. Medication method: The interval between two oral doses of Xidabenzamide should not be less than 3 days (such as Monday and Thursday, Tuesday and Friday, Wednesday and Saturday, etc.), and should be taken 30 minutes after breakfast. During the research process and before the end of medication, the responsible doctor will conduct physical and laboratory examinations on you in accordance with the experimental protocol to evaluate the impact of the experimental drug on you.

Primary Outcome Measures

Name	Time	Method
The efficacy of the investigational drug will be determined by the objective tumor evaluation conducted by the research center based on the RECIL 2017 lymphoma efficacy evaluation criteria	Baseline and testing every 6 weeks	The imaging evaluation methods for tumors are PET/CT, MR, or CT, but the evaluation methods, machines, and technical parameters should be consistent throughout the entire study period. The imaging results are interpreted by researchers or radiologists from each research center. If tumor evaluation has been conducted within 21 days before enrollment and the same methods and machines are used in the same hospital, it can be used as a baseline tumor evaluation. Baseline tumor evaluation should include the nasal cavity, chest, abdomen, pelvic cavity, and any other suspected tumor lesions. If there are clinical indications, appropriate methods can be used to examine any other known or suspected disease site, such as cranial MRI or bone scan.
