Summary

This multicenter, prospective, single-arm clinical trial aims to evaluate the efficacy and safety of N-acetylcysteine (NAC) for treating Transplantation-Associated Thrombotic Microangiopathy (TA-TMA), a severe complication of hematopoietic stem cell transplantation characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ injury, with an incidence of 4%-30%. Current treatments, including plasma exchange (response rate \<10%) and costly complement inhibitors like Eculizumab (71% response) which are not widely accessible, are inadequate. Inspired by NAC's success in treating the related condition thrombotic thrombocytopenic purpura (TTP) and supported by bioinformatic analyses of patient data revealing enhanced oxidative stress pathways and identifying NAC as a potential targeted therapy, our prior study demonstrated that NAC prophylaxis significantly reduces TA-TMA incidence and improves survival. Building on this promising foundation, this study will enroll patients meeting TA-TMA diagnostic criteria for NAC treatment, assessing its potential as a safe, effective, and affordable therapeutic option.

DRUG

N-Acetylcysteine (NAC) Treatment

N-acetylcysteine injection will be administered intravenously to TA-TMA patients at a total daily dose of 16g. The daily dose is divided into two equal doses of 8g each, administered in the morning and evening. Each 8g dose is to be infused over a period of 1 hour. This regimen continues for 14 consecutive days.
