Clinical Trial Summary

The purpose of the study is to assess safety and efficacy of Carnipure tartrate (L-Carnitine and L-tartaric acid - LCLT) supplementation for SARS-Cov-2 infection

Description:

After being informed about the study and potential risks, all patients given written informed consent will be divided em two cohorts according to inclusion criteria.One group with patients with diagnosed mild SARS-Cov-2 infection and another with healthy contacts of patients with diagnosed mild SARS-Cov-2. Both groups will be randomized to receive either LCLT supplementation or placebo during 21 days. After this period primary endpoints of efficacy will be assessed. Clinical follow up evaluations will be monitored (Cohort 1 and 2), and chest tomography will be monitored in cohort 2 as well. Subjects will be followed for safety through 8 weeks (cohort 1) and 6 weeks (cohort 2) after being included into the study.

• Immunosuppressive cytotoxic therapies (e.g., chemotherapy drugs or radiation) in the past 6 months prior to Screening;
• Subjects unable to sign the inform consent to participate into the study;
• History of any other acute or uncontrolled chronic illness (including, hypertension, cardiovascular, pulmonary, neurological, hepatic, rheumatic, hematological, metabolic or renal disorders) that is not on medication regimen for at least the past 6 months;
• Medication or supplements that may interfere with the evaluation of the safety and tolerability of the study drug such as ACE Inhibitors, Angiotensin II Receptor Blockers (ARBs) (e.g. vitamin B3 and L-carnitine/acetyl-carnitine).
