Full description

This study retrospectively collected the data of patients previously treated with Tafa and divided them into two coords according to different protocols received. Cohort 1 was Tafa combined treatment group, which could include Tafa combined with lenalidomide, Tafa combined with Lenalidomide plus BTK inhibitor, Tafa combined with Lenalidomide plus chemotherapy (including ADC). Cohort 2 was treated with sequential CAR T or graft after Tafa combination therapy.

Enrollment: 15 estimated patients
