Interventions
intravenous Anti-CD38 antibody administration This study adopts a prospective, single arm, open design method. Ten subjects were enrolled in the study and were treated with Anti-CD38 antibody (16mg/kg/w) for 8 weeks. The first stage is the main research stage (d1-w8), which is the core treatment period. The subjects will receive intravenous infusion of 16mg/kg Anti-CD38 antibody once a week for 8 weeks to observe the safety and efficacy during treatment. The second stage (w9-w24) is the stage of withdrawal from the visit, mainly to observe the safety and continuous efficacy of Anti-CD38 antibody after treatment.
