A National Multicenter, Real-world Study of Linperlisib in the Treatment of Lymphoma

This is a national multicenter, randomized controlled, open, dose-optimized Phase IV study. It is expected to enroll approximately 88 patients with relapsed/refractory indolent B-cell lymphoma. The aim is to evaluate the efficacy and safety of linperlisib in the treatment of patients with relapsed/refractory indolent B-cell lymphoma at two doses/modes of administration (clinically recommended dose/mode and optimized dose/mode).

Patients were divided to two groups by stratified randomization according to tumor type (FL, CLL/SLL, MZL, others) during the screening period. Both groups were orally administered with a starting dose of 80mg qd for 21 days. On the 21st day of the 4th cycle, if the patient's tumor does not progress and there is no intolerable toxicity, after the researchers determined that medication could be continued, one group of patients continued to take 80mg qd dose continuously, and the other group of patients continued to take 80mg qd dose continuously for two weeks per cycle and stopped for one week, and safety and tumor efficacy evaluation were conducted regularly. The maximum duration of treatment is two years until the disease progresses, toxicity becomes intolerable, or the investigator determines that it is not appropriate to continue treatment.
