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 adverse events (Es).
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.

/ CompletedPhase 2/3

A Prospective Single-blind Comparative Clinical Study of Efficacy and Safety of Amizon 0.25 g Tablets, Manufactured by Farmak JSC, in Patients With ARVI, Including Influenza.

This randomized, single blind clinical study was conducted to investigate the clinical efficacy and safety of the drug Amizon (enisamium iodide), in comparison with placebo for the treatment of patients with acute respiratory viral infections (ARVI), including influenza. Enisamium iodide is an antiviral small molecule.
Adult patients were enrolled and randomised into 2 groups. On the first day of the onset of symptoms of ARVI, one group of patients took Amizon tablets (active ingredient enisamium iodide) for 7 days; the other group of patients took matching placebo tablets for 7 days. Examination and observation of all participants was done for up to 14 days after the first intake of the study drug.
The effect of treatment was assessed by subjective reporting of the symptoms of ARVI and influenza, using a predefined symptom scale score system.
Objective assessment was performed by measuring vitals signs, laboratory tests (including blood and urine assessment), as well as evaluating the immune status (including measuring the relative concentration of interferon and immunoglobulins).

To the Calculation of Heat-Exchange Parameters During Drying of Enisamium Iodide

Author: Kukhlenko, A. A. ; Ovcharenko, A. G. ; Ivanov, O. S. ; Karpov, A. G. ; Vasilishin, M. S.

Issues with thermal calculation of the process of drying the antiviral agent enisamium iodide under pilot production conditions are considered.Calculation of the heat-exchange intensity using the exptl. relation between the Rehbinder criterion and the moisture content of the material was proposed.An empirical equation for calculation of the average temperature of a dryable material is derived.Satisfactory convergence between the calculated and exptl. data makes it possible to use them in the development of an automatic process control system.

4-[(Benzylamino)carbonyl]-1-methylpyridinium halogenide salts: X-ray diffraction study and Hirshfeld surface analysis

Article

Author: Shaposhnik, Anna M ; Baumer, Vyacheslav M ; Levandovskiy, Igor A ; Shishkina, Svitlana V ; Rudiuk, Vitalii V

Two salts of 4-[(benzylamino)carbonyl]-1-methylpyridinium (Am) with chloride (C14H15N2O+·Cl−) and bromide (C14H15N2O+·Br−) anions were studied and compared with the iodide salt. AmCl crystallizes in the centrosymmetric space group P21/n while AmBr and AmI form crystals in the Sohncke space group P212121. Crystals of AmBr are isostructural to those of AmI. The cation and anion are bound by an N–H...Hal hydrogen bond. Hirshfeld surface analysis was used to compare different types of intermolecular interactions in the three structures under study.

Infections with respiratory viruses constitute a huge burden on our health and economy. Antivirals against some respiratory viruses are available, but further options are urgently needed. Enisamium iodide (laboratory code FAV00A, trade name Amizon) is an antiviral marketed in countries of the Commonwealth of Independent States for the treatment of viral respiratory infections, but its clinical efficacy and mode of action are not well understood.
