Effect of Daily Oral Administration of Food Supplement NLC-V in Patients Diagnosed With COVID-19

A Phase II, Randomized, Double-blind, Placebo Controlled Clinical Study Designed to Evaluate the Effect of Daily Oral Administration of Food Supplement NLC-V in Patients Diagnosed With COVID-19

This study is designed to evaluate the safety and efficacy of NLC-V in patients diagnosed with COVID-19.

Herbal remedies and purified natural products provide a rich resource for the development of new antiviral drugs. The detection of antiviral mechanisms in these natural substances sheds light on where they interact with the viral life cycle, such as penetration, replication, assembly and release of the virus, as well as on tuning to specific host-virus interactions. CoV is a virus that belongs to the corona virus family. The CoV virus family causes infections in the upper respiratory tract and gastrointestinal tract in mammals and birds. In humans, it mainly causes colds, but complications can also occur, such as pneumonia and severe acute respiratory syndrome. Corona virus with the known acute respiratory syndrome caused a global threat with high mortality in 2003, and again in 2019 and 2020.

The plant family of lithosperm, have been used in traditional Chinese medicine for the treatment of external wounds, burns or dermatitis for centuries. Studies conducted over the past 30 years have shown that there is a scientific basis and pharmacological properties. The active ingredients that were successfully extracted from the plant were found to be strong inhibitors of the enzyme family found in corona virus polypropylene 3C. Aim of the study: This study was designed to evaluate the efficacy of NLC-V in patients diagnosed with COVID-19.

Details of the research and clinical follow-up phases: A total of 66 adult patients with a certified diagnosis of SARS-CoV-2 virus infection, who are hospitalized due to the infection, will be recruited. NLC-V study therapy is given in oral capsules. Each NLC-V capsule contains 100 mg of active ingredients in a special formulation. Patients will be randomly assigned a 1: 1 ratio to receive NLC-V or placebo, which are additionally given.

Inclusion Criteria:

1. Men and Women aged 18 (inclusive) and above.

2. Confirmed SARS-CoV-2 infection by RT-PCR If confirmed >5 days before the randomization, another test will be taken on day 1.

3. Hospitalized COVID-19 patient in stable moderate condition to upper scale of severe condition (i.e., not requiring full respiratory assessment).

4. Oxygenation < 96% on room air.

5. Subjects must be under observation or admitted to a controlled facility or hospital due to lung infection / respiratory infection only (home quarantine is not sufficient).

5. Known to have severe allergic reactions to one of the study drug components.
6. Active tuberculosis (TB) infection.
7. Subjects diagnosed to suffer from concomitant active infection: bacterial, fungal, viral, or other infection cause besides COVID-19.
8. In the opinion of the investigator, progression to death is imminent and inevitable within the next 24-36 hours, irrespective of the provision of treatments.
9. Treatment with immunosuppressive or immunomodulatory therapy (including tocilizumab) within the past 3 months (steroids are permitted).
10. Participating in other drug clinical trial.

12. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 5 x upper limit of normal (ULN) detected within 24 hours of screening (according to local laboratory reference ranges).
13. Absolute neutrophil count (ANC) < 1000/uL at screening.
14. Platelet count < 50,000/uL at screening.
15. Body weight < 40 kg or >120 kg.
16. Treatment with other investigational drug within 5 half-lives or 30 days (whichever is longer) of randomization.
