Descriptive Information
Brief Title  ICMJE A Clinical Study to Assess the Efficacy and Safety of Amizon® Max in the Treatment of Moderate Covid-19
Official Title  ICMJE A Multi-centre, Double-blind, Randomised, Placebo-controlled, Trial to Assess the Efficacy and Safety of Amizon® Max, Manufactured by Farmak JSC, in Combination With Basic Treatment, in Subjects With Moderate Covid-19
Brief Summary

Adult female and male patients, hospitalized with Covid-19 infection (confirmed by reverse transcription polymerase chain reaction [RT-PCR]), will be screened for participation in this prospective, multi-center, double-blind, randomised, placebo-controlled trial.

Enrolled patients will be randomized (1:1) into 2 treatment groups: Group 1 will receive the active treatment with Amizon® Max (international nonproprietary name enisamium iodide), one capsule (each containing 500 mg of enisamium iodide) 4 times daily every 6 hours for 7 days; patients in treatment Group 2 will receive a matching placebo capsule, 4 times daily every 6 hours for 7 days. Patient observation and follow-up are planned for 29 days, unless discharged before Day 29.

The effect of treatment on Covid-19 will be evaluated by time from day of randomization to an increase of at least two points (from the status at randomization) on the severity rating scale (SR), the Time to Clinical Recovery (TTCR) of main Covid-19 symptoms / complications and the Sum of Severity Rating from Day 2 to Day 15 (SSR-15). Safety and tolerability of the study drug will be evaluated based on the intensity and course of treatment-emergent adverse events (TEAEs).

Enisamium iodide is an antiviral small molecule. Enisamium inhibits replication of alpha- and beta- coronaviruses (human coronavirus NL63 and SARS-CoV-2, respectively) and influenza virus A and B. Mechanism of action against SARS-CoV-2 includes the direct inhibition of the viral RNA polymerase.

Detailed Description

This randomized, prospective, multi-center, double-blind, placebo-controlled trial, is conducted to investigate the clinical efficacy and safety of the drug Amizon® Max (N-methyl-4-benzylcarbamidopyridinium iodide, international nonproprietary name enisamium iodide, lab code FAV00A) in comparison with placebo, for the treatment of hospitalized patients with RT-PCR confirmed Covid-19 infection.

Enisamium iodide is an antiviral small molecule. Enisamium can directly inhibit influenza viral RNA replication and has antiviral effect against viruses, including coronaviruses (human coronavirus NL63, SARS-CoV-2).Based on the promising in-vitro anti-SARS-CoV-2 activity, it could be assumed that patients suffering from Covid-19 would benefit from a reduced virus load and this could lead to a reduction of Covid-19 typical symptoms that might prevent further complications associated with severe Covid-19 (e.g. active mechanical ventilation).

Adult female and male patients, with Covid-19 infection, will be screened (Day 1) to participate in this trial. If all inclusion/exclusion criteria are fulfilled, randomization to treatment and a start of treatment will occur on Day 1.

Patients will be randomized into 2 treatment groups (1:1) as follows: patients in treatment Group 1 will receive the active treatment with Amizon® Max capsule; patients in treatment Group 2 will receive a placebo capsule. The active treatment and placebo capsules are identical in appearance and size.

Patients will take Amizon® Max capsules 500 mg (active ingredient enisamium iodide) 4 times a day every 6 hours (total daily dose 2,000 mg) for full 7 days. In the control group, patients will take placebo tablets 4 times a day for full 7 days. Patient observation interval is for as long as a subject is hospitalized Day 1 to Day 29. A follow-up visit will be performed on Day 29 (by phone as applicable for all subjects discharged from the hospital before Day 29).

The effect of treatment on Covid-19 will be evaluated by the time from the day of randomization (Day 0) to an improvement of at least two points (from the status at randomization) on the severity rating scale (SR), the Time to Clinical Recovery (TTCR) of main Covid-19 symptoms / complications and the Sum of Severity Rating from Day 2 to Day 15 (SSR-15).

Additional outcome measures of efficacy include the 'Days Alive' and 'Out of Hospital' from Day 1 until Day 15 (DAOH-14), the proportion of subjects discharged by Day 8, 15, 22, and 29, the incidence of complications (i.e. pneumonia, need for transfer to intensive care unit [ICU]), the incidence and days until occurrence of pneumonia, incidence and days until supplemental oxygen / high flow oxygen, incidence and days until (non-invasive / invasive mechanical ventilation), incidence and days until transfer to ICU, incidence and time to death, time to virus free, measurement of vital signs (i.e. fever (body temperature), respiratory rate, peripheral capillary oxygen saturation [SpO2]) and the course of symptoms of Covid-19.

Symptom severity for headache, sore throat, cough, shortness of breath, rhinorrhoea, fatigue, myalgia, diarrhoea will be monitored. Safety and tolerability of the study drug will be evaluated based on the intensity and course of treatment-emergent adverse events (TEAEs), safety laboratory tests, as well as the investigator's and subject's overall assessment of tolerability of the treatment.
