inflammatory cytokine, the producers of which in the human body are 
natural killer cells, CD4 Th1 cells and CD8 cytotoxic suppressor cells.  
Macrophages, neutrophils, natural killer cells, cytotoxic T-lymphocytes 
have receptors for interferon gamma. Activates the effector functions of 
these cells, their bactericidal activity, cytotoxicity, production of 
cytokines, superoxide and nitrous oxide radicals (thereby causing the 
death of intracellular parasites). Cancels the suppressive effect of 
interleukin-4 on interleukin-2-dependent proliferation and generation of 
lymphokine-activated killers. Activates the production of proteins of the 
acute phase of inflammation, enhances the expression of genes C2 and 
C4 components of the complement system. 
Unlike other interferons, it increases the expression of major 
histocompatibility complex (MHC) antigens of both classes I and II on 
different cells and induces the expression of these molecules even on 
those cells that do not express them constitutively. This increases the 
efficiency of antigen presentation and the ability of their recognition by 
T-lymphocytes. 
Interferon gamma blocks the synthesis of β-TGF, which is responsible 
for the development of lung and liver fibrosis. 
Release form: Lyophilizate for the preparation of a solution for 
intranasal administration in vials of 100,000 IU per 1 vial. 1 vial of drug, 
1 vial of water for injection (5 ml) and 1 cap-dropper made of 
polyethylene in packaging of polyethylene or medical dropper in contour 
cellular package or in cassette contour package. 
Method of administration and dosage: Intranasally. 2–3 drops in each 
nasal passage every other day 30 minutes before breakfast for 10 days. 
After instillation, it is recommended to massage the wings of the nose 
with your fingers for several minutes to evenly distribute the drug in the 
nasal cavity. Preparation: The contents of the vial are dissolved in 5 ml 
of water for injection. 
Effects on ability to drive and use machines: Not studied.

muscle pain, joint pain, weakness, which develop after the first injections of the drug and are 
amenable to correction with drugs with antipyretic and analgesic effects, without requiring 
withdrawal of the drug. In most cases, fever did not rise above 37.5 °C and was controlled 
independently.  
Basically, registered side effects were reversible and easily controlled by the appointment of 
concomitant therapy (antidepressants for depression; antiallergic agents for skin rash): 
thrombocytopenia2*, neutropenia3*, anemia2*, lymphopenia4; autoimmune thyroiditis, allergic 
reactions5; vomiting 2*, nausea2; weight loss, anorexia3; depression; general malaise, 
headaches3, dizziness; rhinorrhea; allergic rash, alopecia6**; myalgia3; increased concentration 
of liver enzymes 3**, increased concentration of bilirubin 3*, creatinine3*, urea 3*, glucose 3**.  
Risks from the use of the studied drug Ingaron® for the course of pregnancy, fetal development 
or for a breastfed child has not been sufficiently studied. In this regard, pregnant and lactating 
women, as well as women capable of childbearing and unwilling to follow reliable methods of 
contraception, as indicated in the inclusion/non-inclusion criteria, are not allowed to participate 
in this study. If a case of a participant's pregnancy is detected during the study, she is excluded 
from the study ahead of schedule and is subject to medical supervision during the entire period 
of pregnancy, as well as within 6 months after the birth period to assess the condition of the

Introduction 
 
The first coronavirus was isolated back in 1965 from a patient with SARS. But it has been of 
particular interest since the early 2000s, when the first outbreaks of coronavirus infections with 
fatal outcomes began. To date, science knows 37 types of RNA-containing coronaviruses.  
A new coronavirus infection COVID-19 has been observed in the human population since the 
end of 2019. The characteristic symptoms of the disease are fever, cough, shortness of breath, 
myalgia. According to computed tomography (CT), in most cases, bilateral lung damage of the 
"ground-glass opacity" type is registered. Histological examination reports of patients' lungs 
indicate bilateral diffuse alveolar and bronchial [1] damage, pulmonary edema, hyaline 
membrane formation, false respiratory distress syndrome, accumulation of neutrophils, 
macrophages, and lymphocytes [2][3]. A characteristic feature is the presence of synth [4][5]. In 
addition to acute respiratory symptoms, weight loss may be observed [6][7]. 
The first stage of the SARS-CoV-2 life cycle is the adsorption of the viral particle by the target 
cell through ACE2, a receptor different from other types of coronaviruses for introduction into 
the host cell. After receptor binding, the stages of the SARS-CoV-2 viral cycle are similar for all 
coronaviruses [8][9][2 6]. 
The initial outbreak in China was represented in every fifth case by a severe form of the disease. 
The severe course of COVID-19 is associated with the high tropicity of the SARS-CoV-2 virus 
to the lung tissue, which determines its similarity to the pathogenesis of severe acute respiratory 
syndrome (SARS), registered in 2003. Since the beginning of the spread of COVID-19, quite a 
lot of reports have been received about a mild and even asymptomatic form of the disease 
without affecting the lower respiratory tract [1]. 
There is limited information about the systemic and local immune response of the body to the 
SARS-CoV-2 virus and the localization of virus replication in the tissues of the respiratory tract. 
Single scientific works on the study of this problem indicate the activity of replication in the 
tissues of the upper respiratory tract, including the nasal cavity, bronchi, bronchioles and alveoli, 
and the important role of the respiratory organs as "site of entry" for SARS-CoV-2. An important 
difference between SARS-CoV-2 and other epidemiologically important coronavirus strains was 
established, which consisted in the detection of the virus antigen in the ciliated epithelium of the 
nasal mucosa, which was combined with a high risk of transmission of the viral agent, as in cases 
of influenza infections [1]. The condition of a patient with active replication of the virus in the 
upper respiratory tract is of great epidemiological importance, posing a threat of spread [10], but 
may be reversible in terms of the development of subsequent complications and damage to the 
underlying respiratory tract [11]. 
The SARS-CoV-2 virus persists in the pharynx, throat, and lungs during the first week of 
infection and is well detected in a smear from the throat during this time period. At the same 
time, with age, there is a longer release of the virus in the upper respiratory tract [1], which was 
also noted in patients infected with SARS-CoV [12][13]. The detection limit is maximum at the 
beginning of infection. Unlike MERS-CoV, but just as in cases of SARS-CoV, SARS-CoV-2 
infects both type I and type II pneumocytes, which explains the similarity of the histological

picture and explains pulmonary edema and the formation of hyaline membranes. Active 
replication of the virus in the lower respiratory tract is associated with the development of 
complications and lung damage [1][2 6]. Viral RNA can be detected in sputum within a month 
from 
the 
moment 
of 
manifestation 
of 
symptoms 
of 
the 
disease.  
SARS-CoV-2 is also identified in intestinal tissues [14]. Blood and urine samples do not give a 
positive result for the presence of viral RNA [11]. 
By the 14th day of the disease, seroconversion, and an increase in the concentration of IgG and 
IgM antibodies occur in all patients against the background of the remaining viral load [11].  
However, it should be noted that acquired immunity against coronavirus infections is not 
persistent and does not protect against re-infection. Although the severity of the disease is 
associated with age and the presence of concomitant pathologies [1][26], susceptibility to SARS-
CoV-2 is high in all population groups [8][15][16]. 
The interferon system is the most important and integral part of the body's immune system, 
which is responsible for the formation of an immune response, to produce specific antibodies and 
the activation of individual clones of immune system cells responsible for the detection and 
destruction of infectious pathogens: viruses and bacteria. It has been proven that it plays a key 
role in triggering the cellular immune response against any viral expansion, including lethal 
viruses (Ebola, SARS-CoV, MERS-CoV, hepatitis, etc.), which opens promising opportunities 
for the safe use of interferon-based drugs to provide preventive and therapeutic care. 
[18][19][20][21] 
Studies on the role of interferons of different classes in the immune response processes have 
shown that interferons alpha and beta have their own antiviral activity, and interferon gamma is a 
powerful endogenous regulatory cytokine that activates the antiviral immune response, while it 
also has its own antiviral activity.  
One of the unique manifestations of immune influence is the ability of interferon gamma to 
stimulate other cells of the immune system using the mechanism of "antigen presentation". This 
is a process in which phagocytes "place" fragments of pathogen proteins on the surface of their 
cells, thereby presenting these fragments are used by other cells of the immune system to 
develop an antigen-specific response. This mechanism significantly increases the ability of the 
immune system to target respond to a virus or any other intracellular pathogen.  
Drug product called Ingaron (human recombinant interferon gamma), presented in two dosage 
forms: lyophilizate for the preparation of solution for intranasal administration, as well as 
intramuscular or subcutaneous administration, have many years of clinical experience in the 
prevention and treatment of viral infections, including coronavirus, influenza, and pneumonia. 
Efficacy and safety have been demonstrated in randomized controlled and placebo-controlled 
clinical trials [2 2][2 3][2 4]. 
A drug for intranasal administration based on recombinant interferon gamma was studied to 
assess the effectiveness of preventive administration during the epidemic rise in the incidence of 
influenza and ARVI. According to the results of a placebo-controlled randomized trial, the 
incidence during the prevention period and within 1 month after two 10-day cycles of using the 
drug decreased by more than 2 times. Among those who did get sick, a complicated course of 
infection was observed 2 times less often [2-4]. 
The nasal form of the drug has additional advantages. Firstly, a more favorable safety profile was 
noted with intranasal use. Secondly, the form is convenient for use, does not require a violation 

Version2.00

of the skin, does not have an irritating effect on the gastrointestinal tract. But one of the main 
advantages should be noted that the intranasal route of administration contributes to the 
protection of cells, primarily the epithelium of the nasal mucosa, and performs the function of an 
additional mechanical barrier, which can contribute to a more rapid elimination of the virus from 
the upper respiratory tract, prevent its penetration into the lower respiratory tract and provide 
effective preventive protection. 
The drug was included in the training manual "New coronavirus infection COVID-19: etiology, 
epidemiology, clinic, diagnosis, treatment and prevention" [8] and recommended by the Expert 
Council on Science by the Department of Health of the City of Moscow as a preventive measure 
to prevent infection with COVID-19 [15]. 
It is worth paying attention to the fact that during clinical studies to evaluate the antiviral 
efficacy of Ingaron 100,000 IU, a lyophilizate for the preparation of a solution for intranasal 
administration, therapeutic efficacy of the drug was noted in patients with coronavirus infection 
[2 5]. 
In this regard, the following tasks were set in this study: 
• 
to evaluate the effectiveness of the proposed scheme of preventive therapy with Ingaron 
(INN: human recombinant interferon gamma, lyophilizate for the preparation of solution for 
intranasal administration of 100,000 IU) in adult volunteers. Effectiveness includes evaluation 
according to primary and secondary effectiveness criteria. 
• 
to evaluate the safety of the proposed regimen of preventive therapy with Ingaron (INN: 
human recombinant interferon gamma, lyophilizate for the preparation of solution for intranasal 
administration of 100,000 IU) in adult volunteers. Safety is assessed based on adverse events, 
clinically significant changes in laboratory parameters during the study, taking into account the 
assessment of severity according to the STCAE 4.03 scale.

For patients with a registered case of ARVI, duration of participation in the study may be longer, but not exceed 90 days 
1 
All research procedures, except routine laboratory and instrumental studies, the data of which are used to assess the condition of the 
study participant, are performed after the procedure of signing the informed consent of the patient 
2 
The study should indicate the epidemiological history of respiratory viral diseases, status of vaccination (influenza, pneumonia, 
COVID-19), use of means of nonspecific protection and prevention of acute respiratory viral infections, including COVID-19 
3 
It includes a standard examination by a doctor, including: thermometry, assessment of visible mucous membranes of the upper 
respiratory tract, auscultation and percussion of the lungs, palpation of lymph nodes, examination of abdominal organs with 
determination of the size of the liver and spleen, assessment of the level of consciousness; clinical history; measurement of height, 
weight, respiratory rate, heart rate, blood pressure, pulse oximetry with measurement SpO2

If performed as part of a routine practice 
7 
In case of registration of ARVI at the final visit 3, in parallel with the current assessment of the participant's condition, an additional 
assessment of the case is carried out according to the WHO scale, reflecting the maximum clinical manifestation of the disease.      
 
Rules for stopping research 
The sponsor has the right to stop the research at any time. Also, the study may be stopped 
prematurely by the decision of the IEC or regulatory authorities.  
In case of early closure of the research center, all research documentation (except for the one that 
should remain in storage at the center) must be returned to the sponsor. Research documents, 
including primary medical records, must be kept at the center for at least 15 years after the 
completion of the study. 
 
METHODOLOGY OF NON-INTERVENTIONAL RESEARCH 
 
Randomization of study participants 
 
During randomization, patients are randomly distributed in a 1:1 ratio into two groups:  
Group I (main) and Group II (control).

According to the methodology approved by this protocol, the participant must use (Group I) or 
not use (Group II) study drug (depending on the distributed randomization number at Visit 1) for 
27 days of the preventive course (10 days + 7 days + 10 days).  
Randomization of the study participants is carried out on the same day or the next day after 
signing the informed consent, but no later than 3 days from the date of material sampling to the 
PCR test. 
Randomization is carried out according to the Randomization List version 1.00 from 16.11.2020.  
To randomize a participant into a study, a research physician must contact the employee 
responsible for randomization (instructions for randomization are provided by the sponsor to the 
center before the start of the study) by phone and provide the study code and the researcher's full 
name for identification, as well as the data of the randomized participant: screening number, 
initials, date of birth. The researcher is informed of the assigned randomization number of the 
participant and the number of the prevention group (I or II). After the call, a Randomization 
Form is sent to the researcher's email as confirmation. The form must be printed out, signed by 
the researcher, and attached to the primary documentation of the participant.  
The intake of the study drug is carried out independently by the participant at home, with the 
Diary of the participant of the study. 
 
Other preventive measures 
 
Any non-specific measures for the prevention of a new coronavirus infection COVID-19 are 
allowed, including personal protective equipment (respirators, glasses, gloves, protective suits). 
 
Previous therapy 
 
As a previous therapy, it is prohibited to take any drug with test status 1 month before 
participating in this study. 
 
Concomitant therapy  
 
According to the design of the non-interventional study, participants can receive any 
concomitant therapy for concomitant chronic diseases, except medications prescribed off-label or 
for research purposes. 
 
Prohibited therapy 
 
For the study group: use of any medications that may or may have preventive effects against 
ARVI, including COVID-19, is prohibited; use of non-specific methods of preventive protection 
is not prohibited. 
For the control group: use of interferon gamma is prohibited; use of any medications that may or 
may have preventive effects against ARVI, including COVID-19, as well as the use of non-
specific methods of preventive protection is not prohibited. 
All preventive measures, including pharmacotherapeutic ones, should be indicated in the diary 
filled in by the participant.

Exclusion criteria 
A participant should be excluded from the study if at least one of the following criteria is met: 
1. 
The use of the prohibited therapy indicated above, specific to each of the groups. 
2. 
Withdrawal of informed consent. 
3. 
Compliance to the study therapy is 50% or less. 
4. 
Systematic non-compliance with protocol procedures by the participant. 
5. 
Development of individual intolerance to the study drug (for the study group). 
6. 
The development of concomitant diseases or conditions that, according to the researcher, 
may distort the results of the study, restrict the rights of the volunteer or put him at greater risk. 
7. 
The appearance of contraindications to the use of the study drug in the period before the 
last intake of the second 10-day cycle (for the study group). 
8. 
Participation in a clinical trial using a different therapy. 
9. 
Disagreement on following reliable contraceptive measures (sexual abstinence; or a 
combination of 2 different methods: for example, barrier and spermicides, or barrier and 
intrauterine device, or barrier and hormonal, etc.) – for participants with preserved childbearing 
potential in the period before the last intake of the second 10-day cycle (for the study group). 
10. 
Pregnancy. 
A woman who excluded from the study due to the onset of pregnancy during the clinical trial is 
subject to medical supervision during the entire period of pregnancy, as well as for 6 months 
postpartum period to assess the condition of the woman and the born child (observation is carried 
out if possible and only if her desire and consent to such observation is mandatory). Information 
about the course of pregnancy and its outcome is entered in the primary documentation (with the 
consent of the woman). During the entire period of pregnancy, together with an obstetrician-
gynecologist (with the consent of the pregnant woman and, if possible, contact with a doctor), 
observing a woman, her general condition, data reflecting the nature of the course of pregnancy, 
results of laboratory and instrumental examination methods, including ultrasound, are analyzed. 
Monitoring of the born child is carried out with the consent of the woman together with the 
district pediatrician (if possible, contact with him) until the child is 6 months old to analyze the 
clinical status of the child, data from laboratory and instrumental research methods. 
 
There are no procedures for replacing excluded participants.  
 
Diaries of participants 
 
The diaries of the participants (study groups and control groups) are presented in Appendices 1 
and 2. The diaries include 2 blocks to be filled in by the research participant: 1) initial 
information about the participant: initials, gender, date of birth, presence of smoking experience; 
2) information about compliance with the accepted therapy, about the tolerability of preventive 
therapy, cases of ARVI incidence, severity and duration of symptoms, treatment methods. 
To reduce the risk of violation of the dosage regimen, participant diary in the study group 
provides detailed instructions on the preparation, administration and features of the use of the 
drug under study, as well as the diary will contain a calendar for registering the days of

instillations. In addition, when issuing a diary to a participant, it indicates the contact details of 
the doctor for direct communication with the researcher in case of symptoms of acute respiratory 
viral infections during the study period. 
 
Nasopharyngeal smear 
 
Prior to the start of preventive observation, the participant must take a smear from the mucous 
membranes of the upper respiratory tract (nasopharyngeal8). It is allowed to use the results of a 
PCR test before inclusion in the study, but no later than 3 days. If the study is completed with the 
registration of a confirmed case of COVID-19, PCR test is not performed at visit 3, the results of 
the tests performed to confirm the patient's recovery are accepted. 
 
The procedure for working with biological material: 
1. 
The biomaterial is taken on an empty stomach or not earlier than 2 hours after 
eating and drinking; before rinsing, irrigation with medicines.  
2. 
The study is conducted before the start of treatment with antibiotics, antiseptics, 
antifungal and antiviral drugs.  
3. 
Caution should be exercised in the presence of pronounced inflammatory processes 
in the pharynx. In case of severe edema, the material is not taken.  
4. 
The material is taken before carrying out hygienic procedures. 
 
Taking a nasopharyngeal smear for the presence of SARS-CoV-2 RNA is carried out as 
follows:  
1. Scraping of epithelial cells from the oropharynx is carried out with a dry probe, rotational 
movements from the surface of the tonsils, palatine arches and posterior wall of the oropharynx.  
2. Scraping of epithelial cells from the nasopharynx, a smear is taken with a dry sterile probe. 
The probe is inserted with a gentle motion along external wall of the nasal cavity to a depth of 2–
3 cm to the inferior nasal concha. Then the probe is slightly lowered to the bottom, inserted into 
the inferior nasal meatus under the inferior nasal concha and removed along external wall of the 
nasal cavity, producing rotational movements (3–4 cm in children and 5–6 cm in adults).  
3. After taking the material, the tampon should be placed in a sterile disposable tube of the type 
"Eppendorf" with 500 ml of transport medium, mix with a few neat movements, squeeze the 
tampon on the inside "Eppendorf", remove the probe and the working part of the tampon – do 
not leave it in Eppendorf. Next, close the cap of the test tube tightly, sterilize with a disposable 
alcohol wipe, wait for drying and label. 
4. The probe and its working part must be disposed of immediately after inoculation in 
Eppendorf according to the rules for the disposal of potentially infected material (Class B 
waste). 
Scraping from the oropharynx is performed with the maximum possible pressure. At the same 
time, the participant should not experience pain or discomfort, but it is necessary to press cotton 
swab as tightly as possible. 
                                                 
8 It is permissible to accept the results of a nasal or pharyngeal smear, as well as the results of studies performed 
before inclusion in the study for no more than 72 hours.

Both smears are placed in the same test tube to create the highest possible concentration of the 
virus (if present). 
 
Labeling and packaging: 
1. A test tube of the type "Eppendorf" should be treated with an alcohol wipe (after taking 
the biomaterial and closing cap Eppendorf, let it dry (2-3 seconds) and stick-on 1st 
barcode; 
2. Eppendorf with the taken material should be placed in a packaging bag with zip lock. It is 
allowed to place material from only one patient in one packaging bag.  
3. Place the sealed bag inside a plastic sterile sputum container (with a red cap). Paste the 
2nd barcode on the sputum container. It is allowed to place material from only one 
patient in one container. 
4. Put the prepared containers in a large zip package (up to 5 containers are included). 
5. To transport the biomaterial, use a separate shipping container. It is necessary to attach 
the "Transfer Acceptance Certificate" (Number of samples. Inscription: to the PCR 
department URGENTLY!). 
      
Transportation: 
1. Transportation of samples is carried out in compliance with the requirements of SP 1.2.036-
95 "Procedure for accounting, storage, transfer and transportation of microorganisms of

biomaterials, in compliance with precautionary measures and the use of personal protective 
equipment (PPE). 
2. The biomaterial is transported to the laboratory at a temperature of +2 ... +8 °C, and if it is 
impossible to deliver the biomaterial to the laboratory within 48 hours, biomaterial should be 
frozen at -20 °C. 
It is allowed to use eppendorfs only with locking systems. Eppendorfs without locking system 
cannot be used since they can open spontaneously. When taking the biomaterial and closing the 
Eppendorf, precautions must be taken especially carefully to prevent the biomaterial from 
entering the environment, because after placing the probe in the Eppendorf and at the time of its 
closure, a slight shaking of the eppendorf and spilling from the test tube is possible.

spermicides, or barrier and intrauterine device, or barrier and hormonal, etc.) – for 
participants with preserved childbearing potential. 
 
Number of participants 
In this study, the main parameter of effectiveness is the proportion of patients with acute 
respiratory viral infections, including COVID-19, at the end of the period of preventive 
administration of the drug. The study is planned to show that in the study group, the number of 
patients with acute respiratory viral infections, including COVID-19, will be significantly less 
compared to the control group.  
The efficiency parameter was selected based on international recommendations for 
manufacturers of medicines and biological products [28]. 
 
The null hypothesis will be tested by comparing the number of cases in the two groups at the end 
of the period of preventive administration of the drug. It is expected that at least 90% of 
randomized patients will be suitable for inclusion in the population of the primary analysis (PP). 
The statistical purpose of the study is a comparative study of the effectiveness of the preventive 
regimen of the drug. In the main group of study I, study drug Ingaron 100,000 IU, lyophilizate, 
will be used to prepare a solution for intranasal administration, 1 time a day every other day for 
10 days with a repeat of the 10-day course of preventive administration after 7 days of 
interruption.  
To estimate the sample size in this study, an 80% power level was taken (P – probability of not 
missing the present effect is 0.8) and a one-sided level of statistical significance of 5% (α – the 
probability of making an erroneous decision about the presence of an effect is less than 0.05). 
The statistical criteria used are one-sided due to the availability of information about the 
superiority of the effect of the study drug over the lack of preventive measures against the 
nosology being studied [28]. 
Thus, the sample size was calculated based on the following parameters: 
● at the required significance level α= 0.05, the value of Z = 1.96; 
● level of statistical power is assumed to be 80%, the value of Z = 0.84; 
● method of sample formation – randomization using random elements. 
The primary criterion of effectiveness is the proportion of patients with acute respiratory viral 
infections, including COVID-19, at the end of the period of preventive administration of the drug 
(measurement time: 28 days). Secondary efficacy criteria: proportion of patients with confirmed 
COVID-19 at the end of the period of preventive administration of the drug (measurement 
period: 28 days); proportion of patients with acute respiratory viral infections, including COVID-
19, at the end of the follow-up period (change period: 2 months); proportion of patients with 
confirmed COVID-19 at the end of the follow-up period (period of change: 2 months); and the 
frequency of development of complicated course of ARVI.  
The literature analysis conducted on similar studies of the effectiveness and safety of the use of 
interferon-gamma shows that the incidence of ARVI can be observed in 2% of cases in the main 
group of patients taking interferon gamma, as well as in 14% of the control group taking 
alternative methods of protection and representing medical workers working in the "red zone" 
and those at high risk through frequent and prolonged contact with infected patients (p<0.05).

Provided incidence in the control group is from 1 to 5% (taking into account the assumption that 
the incidence in the control group will be approximately equal to the average incidence of the 
general population) [29], and incidence in the study group will be at least 3% lower (which can 
already be considered a minimally clinically significant decrease in incidence in the absence of 
preventive measures with proven effectiveness, which could be taken as a standard), minimum 
sample size should be 630 patients (taking into account 10% of early retirement). Such a sample 
size will also make it possible to establish a decrease in incidence by 4% or more when incidence 
is set at up to 8% in the control group and a decrease in incidence by 6% or more when the 
incidence is set at up to 18% in the control group (Table 1 – Dependence of the sample size on 
various parameters). 
The calculation of the required sample size was performed using a formula for calculating the 
sample size for a qualitative sign [30]: 
 
n 
= 
P1 * Q1 * t2 + P2 * 
Q2 * t2 
(P1− P2)2 
 
Note to the formula:  
P – proportion of cases in which the study sign occurs, 
Q – proportion of cases in which the study sign does not occur, 
t – critical value of the Student's t-test at the appropriate level of significance.  
 
Considering the ratio of the distribution of patients into groups 1:1 with the above parameters, 
the study should complete at least 572 patients: 286 in each group. Considering the possible 10% 
premature exclusion and withdrawal of informed consent, it is necessary to randomize 630 
patients (315 in each group).  
Below is the dependence of the sample size on the parameters of the magnitude of the expected 
effect and the minimum difference that needs to be detected (Table 1 – Dependence of the 
sample size on various parameters).  
Thus, the sample size in each group with a random distribution method will be10:

Thus, in the present study, taking into account the possible 2% exclusion of patients at the 
screening stage due to non-compliance with the inclusion/non-inclusion criteria, it is planned to 
include up to 642 volunteers with a 1:1 distribution in each of the 2 parallel groups (study and 
control), of which up to 321 people will use study drug Ingaron with preventive objective, up to 
321 people, will not use the study drug and will form a control comparison group. 
 
The screening number of the participant is assigned in the order of inclusion of participants in 
the study and consists of numerical character corresponding to the number of the research center 
and three numerical characters of the serial number of the participant in this center. That is, the 
screening number of the first participant in the first center should look like this: 1-001, 
following: 1-002, etc. The screening number of the three hundred and twenty-fourth participant 
of the third center will look like this: 3-324. It is prohibited to re-assign a screening number to a 
participant. The number is unique. 
 
Research hypothesis  
Preventive administration of Ingaron will not lead to a decrease in the incidence of acute 
respiratory viral infections, including COVID-19, among adult volunteers.

● The presence of professional contacts with persons who have a suspected or confirmed 
case of COVID-19 
Or in combination with characteristic changes in the lungs according to computed tomography 
(CT), regardless of the results of a single laboratory test for the presence of SARS-CoV-2 RNA 
and an epidemiological history. 
Also, a possible case of COVID-19 should include a clinical case in the presence of the clinical 
manifestations described above (fever in combination with one or more signs) with characteristic 
changes in the lungs according to imaging studies if it is impossible to conduct a laboratory 
study for the presence of SARS-CoV-2 RNA. 
 
Confirmed case of COVID-19  
A positive result of laboratory test for the presence of SARS-CoV-2 RNA using nucleic acid 
amplification methods or SARS-CoV-2 antigen using immunochromatographic assay regardless 
of clinical manifestations, or a positive result for IgA, IgM and/or IgG antibodies in patients with 
clinically confirmed COVID-19 infection. 
 
In the case of ARVI symptoms characteristic of a suspicious case of COVID-19, accompanied 
by a negative result of PCR test, registered during or after a preventive course (during the period 
of participation in the study after randomization until the end of the observation period), the 
patient may additionally undergo a quantitative test for the presence of IgM and IgG antibodies 
to SARS-CoV-2 by the ELISA method for the purpose of additional verification and detection of 
COVID-19 cases. An additional quantitative test for antibodies to SARS-CoV-2 can be 
performed from the 10th to the 21st day after the appearance of the first symptom of ARVI to 
register the immune response of the acute phase of infection at the beginning of its development 
(increased IgM levels) or during high-grade response (increased IgM and IgG), considering the 
seronegative the period of the disease (5-7 days). The analysis is taken only in the absence of 
fever and a satisfactory general condition of the patient, accompanied by a favorable recovery 
dynamics. When interpreting the results, it is necessary to consider the probability of obtaining 
false positive results (for example, the presence of "cross-reacting" antibodies). If the 
interpretation of the results is difficult, it is allowed to conduct a repeated ELISA study using the 
same test systems after 5-7 days to assess the dynamics of indicators. Quantitative determination 
of IgM and IgG antibodies in the blood by the ELISA method will be carried out with the 
support of DiaLab LLC Plus." 
 
The condition of the study participant is assessed according to the WHO standard scale of 
clinical improvement from 0 to 8 points at each visit, including a phone call visit. In case of 
registration of ARVI at the final visit 3, in parallel with the current assessment of the 
participant's condition, an additional assessment of the case is carried out according to the WHO 
scale, reflecting the maximum clinical manifestation of the disease.

Safety criteria 
 
The assessment of the safety of treatment will be carried out based on registration of adverse 
events by analyzing complaints and subjective symptoms, comparative analysis of clinically 
significant changes in laboratory parameters, as well as the severity of these changes, using the 
CTCAE scale version 4.03 from 2010. 
 
Each participant should be monitored by a researcher for the occurrence of adverse events, which 
should be classified according to the severity and connection with the drug under study during 
the entire period of participation in the study. 
 
Adverse events: 
 
Adverse reaction (AR) – an unintentional adverse reaction of the body associated with the use 
of a drug and suggesting the presence, at least, of a possible relationship with the use of a 
suspected medicinal product. 
 
Adverse event (AE) – any adverse change in the state of health of the patient or the subject of a 
clinical trial to whom the drug (study) product was prescribed, regardless of the causal 
relationship with its use. AE may represent any adverse and unintended change (including 
deviation of the laboratory indicator from the norm), symptom or disease, the time of occurrence

of which does not exclude a causal relationship with the use of drug product, regardless of the 
presence or absence of a relationship with the use of drug product11. 
Symptoms of acute respiratory infection: fever, manifestations of general infectious intoxication, 
signs of respiratory damage are not considered as adverse event, however, they are recorded 
during the study and analyzed as data for evaluating effectiveness. 
 
Assessment of the causal relationship: 
Methods for assessing the degree of causal relationship are based on the following criteria: 
● the presence of a reliable temporary association of the AE with the use of the study drug 
(AE are registered after the start of the use of the study drug before the completion of 
participation in the study); 
● presence of a direct temporary connection of AE with specific administration of the drug 
(for example, development of AE during instillation); 
● possibility of explaining the development of AE by the pharmacological effect of the 
drug; 
● availability of information about such AE as a possible side effect in Clinical 
Investigation Brochure/guidelines for medical use; 
● description of similar cases in the literature; 
● presence of additional specific data indicating the association of AE with the drug (for 
example, the presence of specific antibodies, positive result of allergological tests); 
● positive test with the withdrawal of the study drug (AE was resolved or its severity 
decreased after the drug was discontinued); 
● positive test with repeated administration of the drug under study (AE reappeared or its 
severity worsened with repeated administration of the drug after withdrawal); 
● presence of other reasons for the development of this AE (manifestations of the 
underlying disease, concomitant diseases and conditions, concomitant therapy, food, 
lifestyle, etc.). 
The association of adverse events with the study drug will be evaluated based on the following 
principles in accordance with the WHO classification: 
● reliable – clinical manifestations, including violations of laboratory parameters 
that occur during the period of taking drug s and which cannot be explained by the 
presence of existing diseases and the influence of other factors and chemical compounds. 
Manifestations of an adverse reaction regress after the drug is discontinued and occur 
when it is re-prescribed; 
● probable – clinical manifestations, including changes in laboratory parameters 
associated with the instillation of the drug, which are unlikely to be related to 
concomitant diseases or other factors and which regress with the withdrawal of the drug. 
The response to the rechallenge is unknown; 
● possible – clinical manifestations, including changes in laboratory parameters 
associated with the use of the drug, but which can be explained by the presence of 
                                                 
11 Due to statistical necessity, adverse events are recorded both in the study group and in the control group. 
Evaluation and registration of adverse events begins from the moment of signing the informed consent form.

concomitant diseases or taking other drugs and chemical compounds. Information about 
the reaction to drug withdrawal is unclear; 
● questionable – clinical manifestations, including changes in laboratory 
parameters, which occur in the absence of a clear temporal connection with taking 
medication; there are other factors (drugs, diseases, chemicals) that may be the cause of 
their occurrence; 
● conditional – clinical manifestations, including violations of laboratory 
parameters attributed to "adverse reactions" that need additional data (for an accurate 
assessment) or these obtained data are currently being analyzed; 
● unclassifiable – reports of a suspected adverse reaction cannot be evaluated 
because there is not enough information or it is contradictory. 
● unrelated – clinical manifestations are not associated with the use of the drug. 
 
Serious adverse reaction (SAE) – AE, which leads to death12, poses life threatening13, requires 
hospitalization of the patient or its extension14, leads to persistent or severe disability, to 
congenital anomalies or malformations15, requires medical intervention to prevent the 
development of these conditions. 
 
Unlabeled adverse reaction (unlabeled AE) – an undesirable reaction, nature, severity or 
outcome of which does not correspond to the information in the current instructions for the 
medical use of the drug or in investigator's brochure for unapproved drug. 
All unexpected serious adverse events (unexpected SAE) those recognized by the researcher 
as related to the drug are classified as unexpected serious adverse drug reactions (unexpected 
SAE). Serious adverse drug reaction report form is presented in Appendix 3. 
 
Persistent AE – AE, lasting for a long time, including between cycles of therapy. Persistent AE 
is registered once. If there were no AE symptoms at the visit before the first use of the study 
drug, time of AE completion is the moment when AE is completely stopped. If AE symptoms 
were registered at the visit before the first use of the study drug, time of AE completion is the 
moment when the values of the deviated indicators/severity of AE symptoms (degree according 
to CTCAE) return to the basic (initial) values, i.e., before the use of the product under study. If 
AE symptoms continue at the time of completion of the study, AE registration form is marked 
"ongoing". If AE changes the degree to a higher one (for example, from 1 to 3 degrees), a note 
about the change in AE degree with the date is made in the same AE registration form. At the 
                                                 
12 Death is an outcome, not the SAE itself, so such a name should not appear as a name. If a case of death for an 
unknown reason is identified, researcher should make every effort to identify its suspected causes. SAE in such 
cases can be referred to as "Death by unexplained cause" only in cases where the causes of death are not known and 
cannot be clarified. In case of a fatal outcome due to COVID-19, the information is recorded in the primary medical 
documentation of the study participant without registration of the SAE.  
13 The term "Life threatening" in this context means that the volunteer participating in the study was at immediate 
risk of death during the occurrence of adverse event. This term does not apply to cases where adverse event could 
hypothetically cause the death of a participant if it were more intense in severity or longer in duration. 
14 Hospitalization for optional or pre-planned treatment of concomitant diseases that the participant had prior to 
inclusion in the study, the course of which did not worsen during participation in the study, is not considered to 
SAE, as well as being in a hospital for less than 24 hours or hospitalization for social reasons. 
15 Pregnancy cases in the participants of the clinical study are not subject to registration as AE, except in cases when 
the child has congenital anomaly or malformation (case is registered as AE).

same time, when closing AE registration form, maximum severity of AE is indicated, which was 
observed for the entire period of AE persistence as part of the subject's participation in the study. 
 
Recurrent AE – AE, which was completely resolved, for example, during one cycle of therapy, 
and then reappeared, for example, on the next cycle of therapy, while the participant is in the 
study. Each recurrent AE is registered separately. 
 
All AE are registered in the primary medical documentation of the participant based on physical 
examination, survey, and diary records. The following information must be recorded in the 
primary medical documentation (outpatient card) for each AE: 
- 
severity (mild, moderate, severe); 
- 
nature of adverse event; 
- 
relationship with study drug; 
- 
duration (date of occurrence and end date), preferably with an indication of the time interval 
(hours) from the moment of administration of the study drug; 
- 
whether adverse event is serious. 
The severity is assessed using the CTCAE scale version 4.03 from 2010. The CCAE scale 
contains a list of the most frequent AE recorded in clinical study, in tabular format, indicating 
criteria of various degrees of severity (from 1 to 5, where 5 is death as a result of AE). For AE 
that are not in the tabulated list, the severity is determined in accordance with the textual 
description of the degrees of severity. 
The terms "serious" and "severe" are not synonymous. The term "severe" is often used to 
describe the intensity (severity) of a particular event (for example, anemia of severe, moderate or 
mild severity); however, the event itself may be clinically insignificant (for example, severe 
headache). 
The concept of "severe" is not equivalent to the concept of "serious". The criteria of the latter are 
the outcome of the event or the measures, which are usually associated with the elimination of 
life threatening or severe disorders of vital activity. The criterion of seriousness, and not the 
severity of adverse event, should be guided when determining the need for expedited safety 
report of LLC "NPP "Pharmaclon" and authorized agencies. 
The AE notification form is presented in Appendix 4. 
 
Urgent event: 
Urgent events include all serious adverse events. 
All SAE detected during the period from the moment of signing the informed consent, even 
before the application of the first dose of the product under study until the end of the study, are 
subject to registration. The researcher has the right to provide reports on the development of a 
disease that has developed at any time after the established mandatory observation period, but it 
is necessary to provide an appropriate justification for the presence of a causal relationship. 
In the event of a serious adverse event, researcher is obliged to: 
● 
provide (if necessary) the study participant with appropriate qualified medical care, 
including laboratory tests and/or instrumental examinations;

● 
within 24 hours from the moment when the researcher became aware of the occurrence of 
adverse event, send the data to LLC NPP Pharmaclon (contact information: tel.: 8 800 777 
86 04; e-mail: adversereaction@drugsafety.ru ); 
● 
provide a detailed written report as soon as possible; 
● 
continue monitoring the participant until the full resolution of the SAE. 
Any additional information and supporting documentation (blinded copies of the results of 
laboratory tests, procedures, pathologist's report or postmortem epicrisis in case of death, etc.) 
will be provided by the Researcher in additional written messages of LLC NPP Pharmaclon. In 
case of death of a participant, the Researcher is obliged to provide any additional information at 
the request of LLC NPP Pharmaclon. 
The initial report (completed form of notification of AR) and subsequent detailed and additional 
reports should identify the subjects of the study by the unique numbers assigned to them, not by 
the names of the subjects or their addresses and other personal data.  
In connection with the occurrence of serious adverse events, the researcher is obliged to notify 
the ethics committee. The Ethics Committee may, if necessary, discontinue or cancel the study. 
The minimum information that should be included in the initial notification of the occurrence of 
an urgently reported event should contain the identification data of the participant under which he 
passes in the study, identification data of the person reporting the occurrence of this phenomenon 
(full name of the chief researcher or authorized employee), characteristics of the event that 
occurred and its causal relationship with the use of the investigated drug. 
Except those cases when the urgently reported event was sufficiently documented in the initial 
message about its occurrence, the researcher must provide all additional information available to 
him in subsequent messages about the urgently reported event using the same form, the same 
ways of its transmission and the time frame as established for the initial message about the 
urgently reported event. These procedures should continue until AE has been fully documented 
and reported.  
After sending by e-mail the completed SAE notification, researcher must place the originals of 
the initial and subsequent messages about urgently reported events in investigator file. 
Events deemed NOT to require urgent notification include: 
● hospitalization for optional or pre-planned treatment of concomitant diseases that the 
participant had prior to inclusion in the study, the course of which did not worsen during 
participation in the study; 
● hospitalization, death, or life threatening due to the development of complications of 
ARVI (COVID-19) – however, this information is necessarily recorded and analyzed to 
assess effectiveness.      
      
Features of AE registration in some cases: 
      
Lack of preventive effect 
Absence of preventive effect of therapy should not be registered as AE.

AE in the period before taking study drug 
In the presence of deviations of laboratory, physiological and/or instrumental indicators at the 
screening or randomization visit before the first use of the drug, in the future, the following are 
subject to registration as AE: 
● all deviations accompanied by an increase in severity according to the version used; 
● deviations that are not associated with a change in severity, but have, from the 
researcher's point of view, clinical significance. 
If the participant had deviations of laboratory, physiological and/or instrumental indicators at the 
visit before the first use of the study drug, after which the indicators during the study normalized 
or the severity of the deviation changed for the better, and then changed again for the worse, but 
the values of the indicators remained within the same severity according to If the patient was on 
a visit before the first use of the study drug, the phenomenon should not be registered as AE, 
except in cases where it is clinically significant from the point of view of the research physician. 
 
Registration of a disease/syndrome characterized by several symptoms 
In case of registration of a disease accompanied by various symptoms, registration of individual 
symptoms as AE is not required, however, it is recommended to list all the symptoms of the

Accounting of drugs 
The researcher or other responsible persons will keep records of the study drug. 
The researcher is responsible for the fact that the study drugs: 
− stored in proper conditions in a lockable and safe place; 
− scheduled, and the registration of drugs is documented with the indication of the number of 
the participant to whom the drug was issued. 
The control of the study drugs should be documented throughout the study. 
 
Storage of drugs 
The Ingaron® preparation should be stored in a dry place protected from light, at temperature no 
higher than +25 ° C. Ingaron® solution should be stored for no more than 10 days in the 
refrigerator (do not freeze). 
All participants will be instructed by the researcher about the required storage conditions when 
receiving study drug at visit 1. 
 
RESEARCH DOCUMENTATION 
 
Storage of documentation 
The researcher undertakes to keep all documentation on the study, including the original medical 
documentation of the participants (outpatient records, diaries) for 15 years after the completion of 
the study. This documentation regarding the ongoing research should be available for audits and 
inspections by regulatory authorities. 
 
STATISTICAL METHODS 
 
Populations for analysis 
During the statistical analysis, the following populations of participants will be studied: 
❖ All participants included in the study (FAS, Full Analysis Set). This population will be 
used to describe basic characteristics, including demographic and anthropometric 
indicators, data on concomitant diseases, and will also be used as the main population to 
assess performance parameters. In this case, the participant's group will be determined by 
the "intention to treat" (ITT Analysis). 
❖ Auxiliary analysis of effectiveness parameters is planned for all subjects who completed 
the study without significant deviations from the study protocol (PP, Per Protocol).  
 
Methods of descriptive statistics 
For numerical indicators, such as demographic and anthropometric data (body weight, age, 
height, BMI), as well as numerical performance parameters will be calculated: 
• 
Number of missing values (N); 
• 
Minimum value (Min); 
• 
Maximum value (Max); 
• 
Arithmetic Mean (M); 
• 
Standard Deviation (SD); 
• 
95 % confidence interval (CI) for the mean;

• 
Median (Me). 
For qualitative variables (frequency of AE/SAE development, for example), absolute number in 
the n/N format will be given, as well as the percentage (%). 
 
Analysis of basic characteristics 
The distribution of subjects, demographic and baseline characteristics will be presented using 
descriptive statistics methods for all subjects included in the study (FAS-population). An 
intergroup comparison of the basic quantitative characteristics will be carried out using the t-test 
(or the Mann-Whitney test), depending on the type of data distribution. For categorical data, the 
2-criterion or Fisher's exact test will be applied if the expected frequency in any of the cells is 
less than 5.  
Standard methods available in the XLSTAT 2020.3 program will be used for data analysis. 
When analyzing numerical data, preliminary testing of variables for the normality of the 
distribution will be carried out using Shapiro-Wilk's test, as well as a test for asymmetry and 
kurtosis with an indication of the p value when testing the null hypothesis of the normal 
distribution of the variable. In the case of a normal distribution, an intra-group comparison of 
parameter changes is carried out using a paired t-test. For a comparative evaluation, the χ2-
criterion or the exact Fisher test will be used if the expected frequency in any of the cells is less 
than 5. 
 
Significance level 
A significance level of 0.05 will be used in all tests. Correction for the multiplicity of 
comparison is not introduced. 
 
Handling missing data and significance level 
There are no plans to use data reconstruction methods in this study. The probability of a type I 
error (two-way significance level) will be set at 5% for all comparisons. Correction for the 
multiplicity of comparison is not carried out. 
 
Research Report 
The report will be prepared based on the results obtained at the research center. 
The submitted report should have the character of a full-fledged reasoned scientific research with 
a clear description of the amount of work carried out, research methods, principles of the 
detectable preventive effect of the study drug. 
The final report should reflect the number of participants, their characteristics, method, dose and 
duration of use of the study drugs, tolerability and preventive effect when using them. 
The report should reflect the condition of the participants before the appointment of the study 
drug and the dynamics of their condition under the influence of preventive administration, 
occurrence of adverse events, etc. 
Conclusions should be clear and specific, followed by reasonable practical recommendations 
reflecting the expediency of the use of the study drug. 
The report must be approved by the sponsor of the study and certified with the seal of the 
organization.

Instructions for the preparation of the drug INGARON 
1. Gently pull the plastic nozzle on the glass vial, following the direction of the arrows on the aluminum 
guard. 
2. The plastic cap along with part of the aluminum guard will be removed. 
3. In a circular motion, remove the remaining part of the aluminum guard.  
Remove the rubber stopper from the glass vial. 
 
 
4. Open the vial of 
water for injection by breaking off its upper part. 
5. Pour 5 ml of water for injection into glass vial with a dry substance. 
6. Remove the dropper cap from the package and fix it on the neck of the bottle. 
 
 
Due to the need to store the active substance in a full vacuum, the aluminum cap must be hermetic and durable. 
Slowly remove the aluminum guard of the bottle, avoid cuts. If the cap breaks off during removal, you can remove 
the rest of the metal cap with scissors.   
Take vial with Ingaron with liquid inside with both hands and turn it over 10–15 times.  
Put the vial with Ingaron with the liquid inside in the refrigerator and store there for 10 days. For the second course 
of prevention (after 1 week), use the second vial.  
Return the empty ampoules of water for injection together with the used glass vials to the researcher at the next visit. 
Administration 
Course 1. The drug is applied 3 drops in each nasal passage every other day 30 minutes before breakfast for 10 days 
(total of 5 instillations). The use of the drug is carried out according to the following regimen: 
o 
Course 1. Day 1 – mark administration time in your diary 
o 
Course 1. Day 3 – mark administration time in your diary 
o 
Course 1. Day 5 – mark administration time in your diary 
o 
Course 1. Day 7 – mark administration time in your diary 
o 
Course 1. Day 9 – mark administration time in your diary 
This is 1 preventive cycle. Then a break of 7 days. 
Course 2. Drug administration is carried out similarly to Course 1. Preparation of the drug is carried out similarly to 
the algorithm described earlier. Dosage regimen is the same: 
o 
Course 2. Day 1 – mark administration time in your diary 
o 
Course 2. Day 3 – mark administration time in your diary 
o 
Course 2. Day 5 – mark administration time in your diary 
o 
Course 2. Day 7 – mark administration time in your diary 
o 
Course 2. Day 9 – mark administration time in your diary 
If you missed drug administration, mark the day in your diary with a "check mark" and take the next dose the next 
morning 30 minutes before breakfast and then continue using it every other day. Remember that the finished 
solution of the drug is stored for no more than 10 days in the refrigerator. Do not use it after the expiration date. For 
Course 2, use the second bottle, do not use the first bottle, even if the drug is not fully used.
