Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This open label, randomized, controlled, investigator-initiated, multi-centre trial aims to establish metabolic improvements in COVID-19 subjects by dietary supplementation with cofactors N-acetylcysteine, L-carnitine tartrate, nicotinamide riboside and serine plus standard therapy. The primary objective is to assess the clinical efficacy of the combination of metabolic cofactors supplementation and hydroxychloroquine in COVID-19 patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Coronaviruses are a large family of ribonucleic acid viruses that cause mild to moderate upper respiratory diseases in humans. There is an urgent need for COVID-19 therapeutics due to the S-shaped curve expansion of the infections, widespread pandemic status, and global burden. Given the similarities between SARS-CoV-2 and other coronaviruses, and its relative ease of sample acquisition and study, it has been widely accepted that drug repositioning is a promising approach to make available an effective, safety-assured treatment in a timely manner.

This open label, randomized, controlled, investigator-initiated, multi-centre trial aims to establish metabolic improvements in COVID-19 subjects by dietary supplementation with cofactors N-acetylcysteine, L-carnitine tartrate, nicotinamide riboside and serine plus standard therapy. The investigational drug products, the mixture of the four co-factors will be administered as a powder with strawberry aroma to be dissolved in 200 ml of preferably cold still drinking water and be consumed within 5 minutes.

This study is planned as a Phase II / III clinical drug research to be conducted in patients diagnosed with COVID-19. Patients will be ambulatory and after the diagnosis/confirmation of diagnosis, will be sent home with their treatment. However, patients may be hospitalised during this initial examination period due to deterioration in their physical health or due to any medical condition which was not present at admission.

The primary objective is to assess the clinical efficacy of the combination of metabolic cofactors supplementation and hydroxychloroquine in COVID-19 patients. For the primary purpose, the proportion of patients who were hospitalised during the course of disease until 14 days after the initial diagnosis of Covid-19 disease will be compared. Patients who were hospitalised during the 14-day period, but at any time point after consenting will be evaluated as an end-point occurrence.

The secondary aim in this study is to evaluate the safety and tolerability of metabolic cofactors supplementation and hydroxychloroquine combination.

The initial part of the Phase II/III study is planned as a Phase II study which will enrol 100 patients and after an interim analysis it will conclude as a Phase III study (300 patients). Totally 400 COVID-19 disease patients will be randomized on a 3:1 basis to the combination metabolic cofactors supplementation and hydroxychloroquine or hydroxychloroquine+ placebo in eight clinical sites in Turkey.
