A Study of N-acetylcysteine in Patients With COVID-19 Infection

Purpose

The study researchers think that a medication called N-acetylcysteine can help fight the COVID-19 virus by boosting a type of cell in your immune system that attacks infections. By helping your immune system fight the virus, the researchers think that the infection will get better, which could allow the patient to be moved out of the critical care unit or go off a ventilator, or prevent them from moving into a critical care unit or going on a ventilator. The US Food and Drug Administration (FDA) has approved N-acetylcysteine to treat the liver side effects resulting from an overdose of the anti-inflammatory medication Tylenol® (acetaminophen). N-acetylcysteine is also used to loosen the thick mucus in the lungs of people with cystic fibrosis or chronic obstructive pulmonary disease (COPD). This study is the first to test N-acetylcysteine in people with severe COVID-19 infections.

Experimental
mechanically ventilated &/or managed in a critical-care 		This arm is closed to accrual as of September 2020. Patients in both arms will receive N-acetylcysteine IV 6 g/day in addition to supportive and/or COVID-19 directed treatments at the discretion of the treating physician. Patients will receive treatment for a maximum of 3 weeks or until one of the following: Arm A: - Transfer out of the critical-care unit - Extubation - Toxicity - Death
  • Drug: N-acetylcysteine
    Patients in both arms will receive N-acetylcysteine IV 6 g/day in addition to supportive and/or COVID-19 directed treatments at the discretion of the treating physician. Treatment interruptions for up to 48 hours are permissible if there is a clinical indication to hold the study drug. Patients can restart drug if they have been off drug for less than 48 hours. Patients are also eligible to restart N-acetylcysteine treatment on the same treatment arm without reconsent if they are within the 30 day followup period after their prior course of treatment on this protocol.
  • Other: Peripheral Blood
    A total of 16mL of research whole blood will be collected in CPT tubes at baseline, Cycle 2 Day 1 (or as close as feasible, when still coordinating sample collection across patients in a critical-care unit), and at end of study.
