Clinical Trial Summary

Sinusoidal obstruction syndrome (SOS) or hepatic veno-occlusive disease (VOD) is a serious complication that occurs, most often occurring in patients undergoing hematopoietic stem cell transplantation (HSCT), especially in its first thirty days. The morbidity and mortality in this syndrome are considerable, since severe SOS is associated with a mortality of more than 90% in the first hundred days of HSCT.

Some risk factors are modifiable, especially those related to transplantation, but when non-alterable factors are present, preventive measures are needed that can reduce the incidence and / or severity of SOS.

Description:

This is a single-center, randomized, placebo-controlled study to evaluate the efficacy and safety of N-acetylcysteine as prophylaxis of sinusoidal obstruction syndrome in patients undergoing hematopoietic stem cell transplantation Up to date, no approved medications are available for prophylactic treatment of sinusoidal obstruction syndrome in patients undergoing hematopoietic stem cell transplantation. N-acetylcysteine is a drug that has been long used as a mucolytic. And placebo responses contribute to help assess the appropriateness of randomized clinical trials in determining the size of drug effect.

The study will enroll patients undergoing hematopoietic stem cell transplantation to receive sequentially one of two treatment: N-acetylcysteine or Placebo.
