Efficacy of N-acetylcysteine Versus Placebo as Prophylaxis of Sinusoidal Obstruction Syndrome in Patients Undergoing Hematopoietic Stem Cell Transplantation (ALISON)

March 8, 2021 updated by: Jamilla Neves Cavalcante, Instituto Brasileiro de Controle do Cancer

Prospective, Randomized Study Using N-Acetylcysteine as Prophylaxis of Sinusoidal Obstruction Syndrome in Patients Undergoing Hematopoietic Stem Cell Transplantation

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures
