Official title
A Randomized, Placebo-controlled, Blinded, Parallel-group Clinical Trial to Assess the Efficacy of N-acetylcysteine in Adults With Acute Infections or Sepsis and Evidence of Liver Dysfunction: the IMPACT-NAC Trial
Overview
The primary objective of the IMPACT-NAC trial is to assess the effects of N-acetylcysteine on survival and hospital length of stay in adults admitted to the emergency department with acute infection or sepsis and evidence of liver dysfunction. The main question it aims to answer is: does N-acetylcysteine increase the number of days alive and out of the hospital within the first 14 days after enrolment in the trial? To answer this question, we will conduct a randomized, double-blinded controlled trial of 360 participants. Participants will be randomized to either N-acetylcysteine or placebo (normal saline without active drugs). This will be administered as an infusion during four hours within the first day of hospital admission.
Interventions
- Drug N-Acetylcysteine (NAC) Treatment
Intravenous infusion of N-acetylcysteine (200 mg/kg mixed with normal saline to a final volume of 500 ml) administered over four hours.
Primary outcome measures
- Days alive and out of hospital at 14 days post-randomization (DAOH-14) [Time frame: Assessed 14 days post-randomization]
Secondary outcome measures (6)
- Number of participants with one or more serious adverse event within 14 days of randomization [Time frame: Assessed 14 days post-randomization]
- All-cause mortality at day 180 [Time frame: Assessed at 180 days post-randomization]
- Health-related quality of life (HRQoL) at day 180 using EQ-5D-5L [Time frame: Assessed 180 days post-randomization]
- Admission to an intensive care unit (ICU) within 14 days of admission [Time frame: Assessed at 14 days post-randomization]
- Duration of antibiotic therapy from randomization to day 14 [Time frame: Assessed at 14 days post-randomization]
- Time to clinical stability [Time frame: Assessed at 14 days post-randomization]
