Gaziantep Üniversitesi, FARMAGEN-GCP Center, Gaziantep- Turkey 
 
Analytics: 
     
Plasma concentrations of favipiravir will be analysed in LC system 
with appropriate detection system. 
 
GCP Statement: 
 
This study will be conducted to compliance with Good Clinical 
Practice (ICH-GCP), the Declaration of Helsinki (with amendments) 
and local legal and regulatory requirements. 
 
Blood Sampling:  
The samples will be drawn in the clinical study period: at pre-dose* 
and at 0.17, 0.25, 0.50, 0.75, 1.00, 1.33, 1.66, 2.00, 2.50, 3.00, 3.50, 
4.00, 5.00, 6.00, 8.00, 10.00, 14.00, 24.00 hours post-dose (1 x 8 mL 
each; totally 19 blood sample points)  
 
 
 
* Note:  
1. Only in Period I; at t0 the blood sample amount will be 20 mL. 
2. 
Not to have difficulty to draw blood through catheter; the cannula will be 
kept patent by injecting approximately 0.5 mL of 5 IU/mL of heparin in 
normal saline solution at determined blood sampling points. In such 
cases, before collecting the blood samples at the first blood sampling 
points after heparin administration, first 0.5 mL blood will be discarded. 
The aim of this procedure is to eliminate the possible effect of heparin on 
favipiravir analysis [for   details see section 13.7 (Blood Sampling for Drug 
Analysis)] 
 
Wash-out duration: 
   At least 48 hours. 
 
Acceptance Range: 
 80% - 125% for Cmax and AUC0-tlast of favipiravir.

* Note:  
1. Only in Period I; at t0 the blood sample amount will be 20 mL. 
2. 
Not to have difficulty to draw blood through catheter; the cannula 
will be kept patent by injecting approximately 0.5 mL of 5 IU/mL 
of heparin in normal saline solution at determined blood sampling 
points. In such cases, before collecting the blood samples at the 
first blood sampling points after heparin administration, first 0.5 
mL blood will be discarded. The aim of this procedure is to 
eliminate the possible effect of heparin on favipiravir analysis [for   
details see section 13.7 (Blood Sampling for Drug Analysis)] 
 
Route of   
Administration: 
 
Oral 
 
Duration of Treatment:  
9 days (approximately) including the wash out period of 48 hours and 
the time between last blood sampling in the last period to the final 
examination tests. 
 
Duration of Wash-out:  
At least 48 hours. 
 
 
Procedure:  
In the 1st period, each volunteer will receive after an overnight fasting 
in random order one single oral dose of 200 mg favipiravir product 
(either 1 tablet of the test drug or 1 tablet of the reference drug). Blood 
samples will be drawn immediately before the dosing and at 0.17, 0.25, 
0.50, 0.75, 1.00, 1.33, 1.66, 2.00, 2.50, 3.00, 3.50, 4.00, 5.00, 6.00, 
8.00, 10.00, 14.00, 24.00 hours after the dosing. In the 2nd period there 
will be the same procedure. 
 
Analysis of favipiravir : 
Plasma concentrations of favipiravir will be analysed in LC system. 
 
Statistical analysis: 
Statistical analysis will be performed using Phoenix WinNonlin 
(Version 8.1, Certara L.P.) or above. Analysis of Variance (ANOVA), 
two one-sided tests and 90% confidence intervals for the geometric 
mean ratios (test/reference) of Cmax and AUC0-tlast will be calculated. 
 
Acceptance range: 
Cmax 
: 80-125 % (ln-transformed) 
 
AUC0-tlast 
: 80-125 % (ln-transformed)  
 
 
Evaluation of 
bioequivalence: 
In order to investigate the bioequivalence of all products, the 90% 
confidence intervals will be calculated for the geometric mean ratios of 
test and reference for Cmax and AUC0-tlast of favipiravir. These 
confidence intervals will then be compared with the corresponding 
acceptance ranges. 
 
 
In order to achieve a better approximation to a normal distribution, 
Cmax and AUC0-tlast data for favipiravir will be logarithmically 
transformed (base e) before analysis. The sources of variation will be 
treatments, periods, sequences and subjects within the sequence. 
Evaluation of treatment, period, sequence and subject (nested within 
sequence) effects at 5% level of significance will be performed. From 
the result, the two one-sided hypothesis at the 5% level of significance

will be tested by constructing the 90% confidence interval for the 
geometric mean ratios of test/reference products. The confidence 
interval is calculated by retransformation of the shortest confidence 
interval for the difference of the ln-transformed mean values. 
Differences in tmax will be evaluated non-parametrically.

7. INTRODUCTION 
 
7.1. Chemical and Pharmaceutical Properties 
Favipiravir is an antiviral compound with a wide range of antiviral activity against 
various influenza virus strains. Chemically, it is 6-Fluoro-3-hydroxypyrazine-2-
carboxamide and its molecular formula is C5H4FN3O2. Its molecular weight is 157.10. 
 
Figure 1. Chemical Structure of Favipiravir 
 
 
Favipiravir is a white to light yellow powder. It is sparingly soluble in acetonitrile and 
in methanol, and slightly soluble in water and in ethanol. 
 
 
7.2. Pharmacological Properties 
 
Favipiravir is a drug with a mechanism of action different from that of the existing 
influenza antiviral drugs and effective against all types and sub-types of human 
influenza A, B and C viruses in vitro, showing anti-viral activity against various 
influenza virus strains including avian and swine viruses. Favipiravir also has shown 
anti-viral activity even against amantadine, oseltamivir and zanamivir-resistant 
influenza viruses in vitro. The mechanism of action of favipiravir is the selective 
inhibition of RNA polymerase by favipiravir ribosyl triphosphate formed by cellular 
enzymes in the influenza virus leading to antiviral activity.  
 
 
7.3. Pharmacokinetics  
  
Absorption and Distribution 
 
Following oral administration favipiravir reaches peak plasma concentrations in 
approximately 0.5 hours. After a single 200 mg dose of oral favipiravir tablet to 
Japanese healty volunteers Cmax and AUC0-t were 8.39 µg/ml and 19.67 µg.h/ml 
respectively. The Cmax of favipiravir was linear in the dose range from 30 to 1200 mg, 
while the AUC values at the dose of ≥600 mg remained higher than the value expected 
from the dose-proportional relationship. It is reported thah the pharmacokinetics in the 
dose range in which the pharmacokinetic profiles were linear were compared between 
healthy adult subjects in Japan and the US (when the doses were normalized on the 
basis of a body weight of 60 kg).

When oral tablet of favipiravir was given with a high-fat meal a decrease in Cmax  and 
AUC was observed. 
 
Favipiravir is 53.4%-54.4% bound to plasma proteins.  
 
Metabolism and Excretion 
Favipiravir M1 and glucuronide conjugate of favipiravir (M2) were found in the human 
plasma and urine obtained after single-dose administration.  
The elimination of favipiravir largely depends via renal excretion with a mean plasma 
elimination half-life (t½) of 1.5 hours.

Clinically significant adverse reactions such as, shock, anaphylaxis, pneumonia, 
hepatitis fulminant, hepatic dysfunction, jaundice, toxic epidermal necrolysis (TEN), 
oculomucocutaneous syndrome (Stevens-Johnson syndrome), acute kidney injury

symptoms 
(consciousness 
disturbed, 
abnormal 
behavior, 
deliria, 
hallucination, delusion, convulsion, etc.) haemorrhagic colitis have been reported with 
other anti-influenza virus agents. 
 
7.7. Cautions and Precautions 
 
Administration of favipiravir should be started promptly after the onset of influenza-like 
symptoms. 
 
Favipiravir use is limited with cases in which other influenza antiviral drugs are 
ineffective or not sufficiently effective. 
 
Favipiravir should be administered with care in patients with gout or a history of gout, 
and patients with hyperuricaemia. 
 
Increase of plasma level of favipiravir has been reported in patients with liver function 
impairment in pharmacokinetic study. Necessity of the dose adjustment of favipiravir in 
those patients should be considered. 
 
Although the causal relationship is unknown, psychoneurotic symptoms such as 
abnormal behavior after administration of anti-influenza virus agents including 
favipiravir have been reported. 
 
In case of bacterial infection or suspected to be bacterial infection, appropriate measures 
should be taken, due to favipiravir is not effective in bacterial infections. 
 
 
7.8. Interaction with other medicinal products and other forms of interaction 
 
In vitro drug-drug interaction 
(a)Inhibitory effect against human cytochrome P-450 (CYP) 
In the in vitro CYP inhibition study, the inhibitory effects of favipiravir against major 
human hepatic CYP isoforms (CYP1A2, 2C8, 2C9, 2C19, 2D6, 2E1, 3A4) activity were 
investigated in human liver microsome. As a result, favipiravir inhibited the CYP2C8 
activity in a concentration-dependent manner. The metabolic activities of the other CYP 
isoforms in the presence of favipiravir at the maximum concentration were all ≥60% of 
the control. M1, the major metabolite of favipiravir, decreased the CYP2E1 activity to 
72.6% of the control at the maximum concentration, but hardly inhibited activities of 
other CYP isoforms for any isoforms. 
 
In the case of concomitant use of favipiravir with repaglinide, CYP2C8 substrate drugs, 
it cannot be ruled out that the risk of hypoglycemia, a serious adverse drug reaction, is 
increased. In the case of concomitant use of favipiravir with paclitaxel, it cannot be 
ruled out that the risk of white blood cell decreased and peripheral neuropathy, serious 
adverse drug reactions, is increased.

(b) Induction action on CYPs 
In the in vitro CYP induction study, the effects of favipiravir on human hepatic CYP 
isoforms (CYP1A2, 2C9, 2C19, 3A4) were investigated in fresh human primary 
hepatocytes. As a result, favipiravir increased the expression of the CYP isoforms up to 
1.7 times (mean) in the concentration range examined, and this induction rate of 
favipiravir was ≤6.6% of those of the positive controls (omeprazole, rifampicin). 
 
(c) Inhibitory effect against Aldehyde Oxidase (AO) 
In the in vitro inhibition study, the inhibitory effects of favipiravir against the AO 
activity were investigated in human hepatic cytosol. As a result, the residual metabolic 
activity (phthalazone formation activity) of phthalazine, a substrate of AO, decreased 
favipiravir concentration (20-6000 μmol/L) and preincubation time (0-60 minutes)-
dependently. the risk of concomitant use of favipiravir with AO inhibitors may not be 
high. Currently, a drug interaction study of favipiravir with raloxifene hydrochloride, an 
AO inhibitor, is under preparation, and if the risk of concomitant use is suggested by 
this study, precautions will be provided in the package insert.  
 
Based on the currently available pharmacokinetic data, drugs that act as AO substrates 
and would require special attention are hydralazine hydrochloride, which shows a high 
relative contribution of AO, and famciclovir and sulindac, whose effect may be 
decreased by concomitant favipiravir. 
A drug interaction study with hydralazine hydrochloride is under preparation, and if the 
risk of concomitant use is suggested by this study, precautions will be provided in the 
package insert. 
 
(d) Inhibitory effect against Xanthine Oxidase (XO) 
In the in vitro inhibition study, the inhibitory effects of favipiravir against the XO 
activity were investigated in human hepatic cytosol. As a result, favipiravir did not 
inhibit the metabolism of 1-methylxanthine, a metabolite of theophylline (substrate of 
XO), concentration or preincubation time-dependently. 
 
(e) Interaction with acetaminophen 
In the in vitro inhibition study, the inhibitory effects of favipiravir and M1 against 
acetaminophen metabolism were investigated in human liver S9. As a result, favipiravir 
did not inhibit the glucuronide conjugation metabolism of acetaminophen in the 
concentration range examined, but inhibited the sulfate conjugation metabolism. M1 did 
not inhibit glucuronide or sulfate conjugation metabolism of acetaminophen in the 
concentration range examined. Favipiravir is expected to be concomitantly used with 
acetaminophen in the treatment of influenza infection in many patients. The results from 
this study can serve as important information for clinical use of favipiravir and therefore 
should be included in the package insert for information provision. When the results are 
obtained from other interaction studies ongoing or to be conducted, relevant information 
should be provided to healthcare providers in clinical practice appropriately.

(f) Interaction with oseltamivir 
In the in vitro inhibition study, the inhibitory effects of favipiravir and M1 against 
oseltamivir metabolism were investigated in human liver S9. As a result, favipiravir 
inhibited deesterification of oseltamivir in the concentration range examined, but IC50 
values were high. M1 did not inhibit deesterification of oseltamivir in the concentration 
range examined. 
 
(g) P-gp transportation 
A membrane fraction from the human MDR1 expressing cells was used to investigate 
P-gp’s substrate recognition. As a result, favipiravir and M1 did not increase the 
adenosinetriphosphatase (ATPase) activity concentration-dependently, suggesting that 
neither of them will act as a substrate of P-gp.  
 
In vivo drug-drug interaction 
(a) Theophylline  
Favipiravir and/or theophylline were administered to 10 healthy adult Japanese male 
subjects. For combination therapy with theophylline, subjects received a certain 
regimen. Both favipiravir and theophylline were administered between the meals. It is 
found that the combination therapy with theophylline affected the pharmacokinetics of 
favipiravir and M1. On the other hand, both parameter ratios of theophylline fell within 
the above range. 
 
(b) Oseltamivir  
Favipiravir and/or oseltamivir phosphate were administered to 10 healthy adult 
Japanese male subjects in a certain regimen. Both favipiravir and oseltamivir phosphate 
were administered between the meals. There were no significant differences in the 
cumulative urinary excretion rate or CLr of M1 and oseltamivir carboxylate up to 12 
hours after dosing between the monotherapy and combination therapy. When any new 
relevant finding becomes available after marketing of favipiravir; however, it is 
necessary to provide the information to healthcare providers in clinical practice 
appropriately. 
 
(c) Oral Contraseptive 
In studies conducted according to the proposed dosage regimen, only 1 subject 
concomitantly used favipiravir and oral contraceptives and reported rhinitis and 
dysgeusia as adverse events, which were not considered specific to favipiravir or ethinyl 
estradiol. 
 
(d) Pyrazinamide 
Blood uric acid levels increased in all the subjects treated with favipiravir with 
pyrazinamide, although the effect on the blood drug concentration was not significant. 
As a serious adverse event, hepatic function abnormal was reported as well. Hence, it is 
necessary to collect post-marketing information about patients to whom favipiravir is 
administered in combination with pyrazinamide.

        8. OBJECTIVE OF THE TRIAL 
The aim of this study is to evaluate the pharmacokinetic profiles and the relative 
bioavailability of favipiravir of the Test Drug (Favicovir 200 mg Film Tablet, Atabay-
Turkey) in comparison with Reference Drug (Avigan 200 mg Film Tablet, Toyama Chemical 
Industry Co Ltd.-Japan) under fasting conditions. The primary objective is to demonstrate 
the bioequivalence of all products. 
 
9. BENEFIT-RISK EVALUATION 
For the approval of any product, its efficacy and safety has to be proved. There are two 
possibilities to do this for a new generic product: either by proving therapeutic equivalence or 
by proving bioequivalence with a marketed reference on the basis of comparison of relative 
bioavailability. The first option requires huge numbers of patients and a long period of 
administration of either the test or the reference product. A bioequivalence trial on the basis of 
bioavailability is therefore generally accepted as the better alternative. This trial is conducted 
with the aim to investigate whether any differences concerning the rate and extent of 
absorption exist between the test and the reference products.  
 
10. DESIGN 
In this open-label, randomised, single-dose, two period, cross-over  study, 30 healthy male 
subjects (intention to treat population) will receive one single oral dose of 200 mg favipiravir 
(one tablet of the test drug or one tablet of the reference drug) after an overnight fasting in 
each period according to a sequence determined by randomisation [In each study period, 
subjects will take different products (either one dose of Test Drug or one dose of Reference 
Drug)]. 
Data of the subjects who have completed the study according to the Clinical Study Protocol 
(per protocol population for pharmacokinetic evaluation) will be used for analytical, 
pharmacokinetic and statistical evaluation. 
 
Test Drug: “Favicovir 200 mg Film Tablet” is manufactured by Atabay Kimya San. ve Tic. 
A.Ş., Turkey and is will be licensed by Atabay Kimya San. ve Tic. A.Ş., Turkey. 
 
Reference Drug: “Avigan 200 mg Film Tablet” is manufactured and licenced by Toyama 
Chemical Industry Co Ltd.-Japan.    
  
In study period, the subjects will be admitted to the FARMAGEN Clinical Unit in the evening 
(18:00) prior to morning of the administration of medication after screening and isolation 
period as described in Appendix VII. 
  
Volunteers will be confined to the clinical unit and dosing will occur under conditions of 
hospitalization. Medications will be orally administered at approximately at 8:00 (t=0) 
after an overnight fasting (at least 10 hours in fasting). The lunch will be 4 hours post 
dosing and the dinner will be 10 hours post dosing. Blood sampling for the determination 
of favipiravir plasma concentrations will be drawn at specified time points. In study 
period including wash-out period, volunteers will be hospitalized in FARMAGEN Clinic 
Unit. After taking the last blood sample in 2nd period and carried out the post-study and 
final examination, the subjects will be allowed to leave the clinic.

  12.2. Blinding 
 
12.2.1. For Clinical Phase 
 
This trial is planned as open-labelled in clinical phase. Investigator will have the 
information of which subject will take which product [Test or Reference] in study. 
Also, the subjects will have the information about the products which will be 
administered in the study period. 
12.2.2. For Analytical Phase 
This trial is planned as fully blinded in analytical phase. The exact list will be in a 
sealed envelope and this envelope will be opened at Novagenix in a “Project 
Evaluation Meeting” when all laboratory analyses are over. Once the sealed envelope 
is opened, no more reanalyse or data change/exclusion will be allowed. 
12.3. Dosage, Duration of Treatment 
All volunteers will receive once daily either 200 mg favipiravir of the test drug (in 
one period) or 200 mg favipiravir of the reference drug (in one period) according to 
the randomisation table. The instructions for intake of the study medication are given 

Study Code: NOV2020/01917

in section 13.5 and separately on a sheet to be kept in the room where administration 
takes place.  
12.4. Compliance 
On each day of administration and/or sampling the identity of the volunteer will be 
confirmed 
by 
checking 
the 
Identity 
Card. 
Administration 
of 
the   
study medication will be performed by the investigator(s) and nurse(s)   
and 
supervised 
by 
a 
second 
medical 
professional 
to 
ensure 
the   
correctness of drug administration. Also, a personnel (monitor) from Sposor will 
attend during this procedure. The administration of the study medication is to be 
followed by a mouth check, to be documented in the CRF and certified by the 
Investigator. 
12.5. Handling and Drug Accountability 
The study medication will be packed and labelled according to GMP requirements. 
The study medication will be provided by the Sponsor together with certificates of 
analysis in a sufficient quantity for the needs of the whole trial. The Sponsor is 
responsible for keeping an appropriate amount of each study medication at the facility 
or at ALPAN Farma in order to allow repeated pharmaceutical analysis.  
The investigator will confirm receipt of study medication in writing, including all 
follow-up supplies. The investigator will administer the study medication only to 
volunteers included in the study by following the procedures set out in the study 
protocol, as given in chapter 13.2. All drug supplies (test and reference medication, 
unused medication, empty blisters) which have not been used have to be returned to 
ALPAN Farma or Atabay Kimya San. ve Tic. A.Ş. after completion of the study. It 
is not allowed to use the study medication for any other purpose. 
12.6. Concomitant Medication 
Concomitant medication is generally not allowed for the duration of the trial. If this is 
considered  necessary for the volunteer's welfare, it may be given at the decision of the 
investigator. The volunteers have to inform the investigator about any intake of other 
drugs in the course of the trial. If necessary, for the treatment of ordinary pain (e.g. 
headache), some analgesics which have no drug interaction with study products, may 
be given by investigator. Any intake of concomitant medication has to be documented 
in the Case Report Form (“concominant medication form”, “adverse event form” and 
“drop-out sheet”) specifying the substance, dose, time and reason for use of 
concomitant medication and may be regarded as an exclusion criterion. 
12.7. Rescue Medication 
No specific rescue medication is planned for the present trial since it is not a 
therapeutic trial and the safety / tolerability profiles of the administered drug substance 
are well known.

13. STUDY PROCEDURE 
13.1. General Procedure 
Volunteers eligible for inclusion within the age limits as defined in section 11.1 will be 
asked for informed consent as described in Appendix VII due to the Covid-19 
outbreak precautions and as described in section 20.3 and will be thereafter screened 
with respect to inclusion and exclusion criteria.  
The initial examination will be carried out on the day of the beginning of the isolation 
as described in Appendix VII. The standard clinical screening includes demographic 
data, brief anamnestic data (medical history with information about relevant previous 
diseases of all body systems), physical examination, determination of body 
temperature, weight and height, standard ECG (12 lead), measurements of blood 
pressure (BP) and pulse rate (PR) after 5 minutes supine rest. 
The standard laboratory screening includes serum levels of “CBC, glucose, urea, uric 
acid*, creatinine, estimated GFR (eGFR), total bilirubin, sodium, potassium, 
calcium,chloride, SGOT (AST)*, SGPT (ALT)*, GGT*, alkaline phosphatase, total 
protein and urinalysis”. The blood specimen (20 mL# for entry and 12 mL for final) for 
the safety laboratory will be taken under fasting conditions. Total blood sampling for 
both laboratory examinations (entry and final) will be 32 mL. The volunteers will also 
be checked for presence of HBsAg, HCV-Ab and HIV-Ab in serum and Covid-19 
PCR test.  
Clinical laboratory tests will be performed using the auto analyser at a contracted and         
certified laboratory (GAMA Tıp Laboratuvarı-Gaziantep). Covid-19 PCR test will 
be performed at “FARMAGEN-GCP Center, Gaziantep- Turkey”.  
* SGOT (AST), SGPT (ALT), GGT and uric acid levels should be within normal 
range for entry examination. 
#  At entry examination the blood sample amount will be 20 mL and 8 mL sample of 
20 mL sample will be divided into tubes and one of this tube will be used for the anti-
coagulant validation purpose during the analytical validation process. This plasma 
sample will send to Novagenix with master and back-up samples. 
The following parameters are determined in urine (30 mL): pH, protein, glucose (semi 
quantitatively by means of strip test), ketones, blood, leukocytes, bilirubin, nitrites. If 
the strip test for any urine parameter is positive, a microscopic examination of the 
sediment has to be done. 
At screening volunteers will be requested to provide a urine sample for a drug screen 
which will include “amphetamines, cannabinoids, benzodiazepines, cocaine, opioids 
and barbiturates” and for an alcohol breath test. All laboratory tests will be carried out 
in a certified local laboratory. A list of the normal ranges and units of measurement of 
the laboratory parameters to be determined during the study and the certificate of the 
laboratory will be provided by the investigator before the start of the study. The 
reference ranges and the results of the individual laboratory examination will be 
documented in each CRF. The investigator will be provided with a print-out or 
authorized copy of the original laboratory values. 

Study Code: NOV2020/01917

If in the course of initial screening any clearly pathological value (laboratory value 
outside reference range, clinically relevant or significant) is observed, this finding will 
be regarded as an exclusion criterion. 
Laboratory values outside the normal range will be judged by the investigator in a 
written form in the CRF. Single laboratory values outside the normal range will 
generally not be regarded as an exclusion criterion provided that: 
a) they are not accompanied by clinical symptoms, 
b) the context of related laboratory values gives no indication of a pathological 
process and 
c) the investigator regards them as clinically irrelevant in written form in the CRF.  
If any positive result in Covid-19 PCR test is observed, the volunteer will be 
transfer to Gaziantep University Şahinbey Research Hospital, Emergency 
Department* under appropriate conditions immediately. This finding will be 
regarded as an exclusion criterion.

The test and reference product will be administered under fasting conditions each in 
a randomised manner in two-period with at least 48 hours wash-out 
period.Volunteers will be treated under hospitalization conditions in study period and 
will be hospitalised at the Clinical Facility (FARMAGEN-Good Clinical Practice and 
Research Center)  from the evening of  Day 0 (hospitalization day) normally until 
taking the last blood sample in 2nd period and carried out the post-study and final 
examination to ensure subjects’ safety as well as standardised trial conditions during 
profiling days (e.g. in view of food and fluid intake, diet, fasting conditions, drug 
administration, clinical and other procedures). Adverse events will be monitored 
throughout the study. The medical care of the volunteers will be guaranteed by the 
presence or stand-by of the investigator or one of the co-investigators throughout the 
clinical phase of this trial. 
The volunteers will come to the clinic from isolation, described at Appendix VII, at 
approximately 18:00 on the day before the treatment (Day 0) and will remain there for 
90 hours. A measurement of body temperature will be performed once a day in the 
mornings during the study period.They will not be allowed to drink water between 1 h 
before to 1 h after administration, except while dosing (the total intake of water on the 
days of dosing will be maximum 1.5 L). The investigator will check on each 
volunteer's wellbeing prior to their discharge from the clinic. If necessary, some 
volunteers will remain at the clinic until any adverse events have resolved. All 
volunteers will be subjected to a post-study and final examination and laboratory tests 
on the day of  last sampling in second period. 
For each volunteer being withdrawn from the study prior to regular termination of the 
individual study period, due to whatever reason, a complete final examination has to 
be performed at the time of withdrawal as far as possible with regard to the volunteer's 
health conditions and as far as necessary with regard to safety aspects. All taken

laboratory tests. 
After sampling the blood samples for pharmacokinetic analysis, the tubes will be immediately 
refrigerated at 2 - 8°C and will remain there for not more than 30 minutes. After centrifugation (3.000 
rpm, 4 - 6°C, 10 min), the separated plasma from each sample will be transferred into two 3 mL 
transparent, polypropylene tubes per sample (at least 1.5 mL per tube). All the aliquoted plasma 
samples will be flash freezing immediately. The flash frozen samples (aliquoted plasma samples) 
will be transferred to a deep-freezer and stored at -70°C.  
 
At the end of the study one aliquot will be shipped on dry ice (solid CO2) according to 
the sample transport SOP of FARMAGEN-Good Clinical Practice and Research 
Center by courier for the determination of plasma drug concentrations to the analytical 
laboratory: 
Novagenix Bioanalytical Drug R&D Centre  
Esenboğa Yolu 25. Km.  
Ankara-Turkey 
As precautionary measure, the other aliquot will at first be retained at the clinical unit 
in case that any adverse conditions, for example due to transport damage of the first 
shipment.Once the bioanalytical laboratory confirms receipt of the first shipment, the 
second set of aliquots will be sent. 
The samples will be packed on dry ice for transport, no interruption of the freeze chain 
is allowed and also data loggers will be included for temperature recording. 
All labels for blood and plasma samples will be provided by NOVAGENIX and will 
contain the following information: active ingredient name, study code, subject number, 
period, tube number and time (e.g. 2 h post-dosing). An example is given below:

14. PREMATURE DISCONTINUATION 
The conditions for premature discontinuation of the trial in some particular volunteers 
or in general are summarized in this chapter. 
 
       14.1. Withdrawal of Volunteers 
Volunteers may be withdrawn for the following reasons: 
 at their own request with or without giving reasons, 
 at the discretion of the investigator for reasons of medical prudence. 
In either event, the Sponsor will be immediately notified and the date and reasons for 
the withdrawal will be clearly stated in the volunteer's CRF. 
      Volunteers must be withdrawn under the following circumstances: 
 if personal circumstances suggest that the visits required by the protocol cannot be 
guaranteed any longer, 
 if Covid-19 PCR test result is positive, the volunteer(s) will be dropped out from 
study. 
 if adverse events (including intercurrent illnesses) develop, which rule out 
continuation of the study medication, or, due to impaired validity of the results, make 
it appear inadvisable to further participate in the study, 
 
 if subjects who have intaked or administrated of any prescribed systemic or topical 
medication (including OTC medication) within 2 weeks of the start of the study 
(except singles doses of analgesics which have no drug interaction with study 
products) given in case of an adverse event (e.g. headache) during the study, 
 if circumstances defined as exclusion criteria are registered, 
 if administration of any drug is necessary, which is not permitted according to the 
exclusion criteria (see section 11.2), independently of its necessity due to the 
occurrence of adverse events (including intercurrent illnesses) or of its use due to other 
reasons, 
 if vomiting occurs at or before 2 times median tmax.  
 if diarrhea exists during screening and /or medication day. 
 
14.2. Replacement of Drop-outs 
 
A total of 30 volunteers will be enrolled in the trial. If drop-out exists in isolation or in 
study period, then these dropouts WILL NOT BE replaced.  
For each volunteer being withdrawn from the study prior to regular termination of the 
individual study period, due to any reason, a complete final examination has to be 
performed on the day of drop-out, as far as possible with regard to the volunteer's 
health conditions and as far as necessary with regard to safety aspects and the validity 

Study Code: NOV2020/01917

of study results. The reason for withdrawal has to be documented in the case report 
form and in the volunteer's medical records. 
 
 
14.3. Early Termination of the Study 
 
The Sponsor may discontinue the study at any time. 
If, in the opinion of the investigator, the clinical observations in the study suggest that 
it might not be justifiable for medical reasons to continue, she/he may terminate the 
study after consultation with the Sponsor or the Sponsor may terminate the trial for 
safety, administrative or other reasons. 
Reasons for discontinuation have to be documented appropriately and to be provided 
to the Sponsor and the Ethics Committee and MoH. In case of premature 
discontinuation of the study a complete final examination has to be performed for each 
volunteer as far as possible with regard to the volunteer's health conditions and as far 
as necessary with regard to safety aspects and the validity of study results. 
 
14.4. Drop-out Samples 
All drop-out samples which will be sent by the clinic will be analysed and results will 
be given in the Final Study Report.

15.  ADVERSE EVENTS 
 
15.1. Definition of Adverse Event / Serious Adverse Event / Adverse Drug 
Reaction / Unexpected Adverse Drug Reaction 
An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product which does not 
necessarily have a causal relationship with this treatment. 
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding, for example), symptom, or disease temporally associated with the 
use of a medical product, whether or not considered related to the medical product. 
A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose: 
 
results in death 
 
is life-threatening 
 
results in persistent or significant disabling/ incapacity 
 
requires inpatient hospitalization 
 
prolongs inpatient hospitalization 
 
is a congenital anomaly/birth defect 
An adverse event is defined as an Adverse Drug Reaction (ADR) if further analyses 
prove that the adverse event was caused or partially caused by the study medication: 
In the pre-approval clinical experience with a new medicinal product or its new usage 
all noxious and unintended responses to a medicinal product related to any dose should 
be considered adverse drug reaction. The phrase ''responses to a medicinal product'' 
means that a causal relationship between a medicinal product and an adverse event is 
at least a reasonable possibility, i.e. the relationship cannot be ruled out. 
Unexpected Adverse Drug Reaction (UADR) is an adverse reaction, the nature or 
severity of which is not consistent with applicable product information (e.g., 
Investigator's Brochure for an unapproved experimental medicinal product, summary 
of product characteristics for an approved product) or events previously unobserved or 
undocumented which are not on the basis of what might be anticipated from the 
pharmacological properties of a medicinal product. 
In the course of the study, the investigator will determine whether any adverse events 
have occurred and will grade their intensity as follows: 
- Mild:  
Awareness of symptoms but easily tolerated 
- Moderate:  Discomfort enough to cause interference with usual activity 
- Severe:  
Incapacitating with inability to work or to carry out usual activity. 
 
15.2. Relationship to the Study Medication 
The investigator will make judgement considering whether or not, in his opinion, the 
adverse event was related to the drug according to the following classification. 
However, even if the investigator feels that there is no relationship to the drug, the 
adverse event should be reported. 

Study Code: NOV2020/01917

The likelihood of the relationship of adverse event to the study drug is to be recorded 
as follows. 
Causality assessment of suspected adverse reactions (criteria defined by members of 
WHO Drug Monitoring Programme): 
Certain:  A clinical event, including laboratory test abnormality, which occurs in a 
plausible time relationship to drug administration, and which cannot be 
explained by concurrent disease or other drugs or chemicals. The response to 
withdrawal of the drug (de-challenge) should be clinically plausible. The 
event must be definitely pharmacological or phenomenological, using a 
satisfactory re-challenge procedure if necessary. 
Probable/likely: A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to administration of the drug, unlikely to be 
attributed to concurrent disease or other drugs or chemicals, and on which a 
clinically reasonable response on withdrawal (de-challenge) follows. Re-
challenge information is not required to fulfil this definition. 
Possible: A clinical event, including laboratory test abnormality, with a reasonable 
time sequence to administration of the drug, but which could also be 
explained by concurrent disease or other drugs or chemicals. Information on 
drug withdrawal may be lacking or unclear. 
Unlikely: A clinical event, including laboratory test abnormality, with a temporal 
relationship to drug administration which makes a causal relationship 
improbable, and in which other drugs, chemicals or underlying disease 
provide plausible explanation. 
Conditional/unclassified: A clinical event, including laboratory test abnormality, 
reported as an adverse reaction, about which more data is essential for a 
proper assessment or the additional data are under examination. 
Unassessable/unclassified: A report suggesting an adverse reaction which cannot be 
judged because information is insufficient or contradictory, and which cannot 
be supplemented or verified.

15.3. Reporting and Documentation of Adverse Event(s) 
AEs/ADR will be assessed by spontaneous, unsolicited reports of the volunteers, by 
observation and by routine open questionings of the volunteers. Questionings will be 
done by experienced staff of FARMAGEN-Good Clinical Practice and Research 
Center during admission to the clinical facility and at least at the following times of 
the study period: at Day 0, pre dose and t1.00, t4.00, t8.00, t14.00, t24.00 hours after the drug 
administration. If any adverse event occurs, it will be recorded on the Adverse Event 
Report page of the CRF. All findings will be recorded in English. The documentation 
includes type of AE/ADR, date and time of onset, treatment initiated (if applicable), 
outcome, intensity/severity code (mild, moderate, severe) and whether the event is 
serious. It is important that the investigator immediately reports any adverse event 
which by the definitions given above would be considered serious, even if the 
investigator does not consider the adverse event to be clinically significant or drug-
related.  
Occurrence of any serious adverse event has to be reported by the investigator 
immediately (within 24 hours), the latest on the next working day, by phone and e-
mail and/or by fax to Atabay Kimya San. ve Tic. A.Ş. or to ALPAN FARMA as an 
initial report. 
As soon as new information about the SAE becomes known, the investigator has to 
forward it without any delay to Atabay Kimya San. ve Tic. A.Ş. or to ALPAN 
FARMA. This applies to the follow-up and/or final SAE report and all medical 
records associated with it. 
A copy of the updated CRF-page for AE and SAE documentation will be forwarded to 
ALPAN FARMA or Atabay Kimya San. ve Tic. A.Ş. as soon as possible.

Serious adverse events will be reported to sponsor and/or CRO by investigator 
immediately. After that, sponsor and/or CRO will report to the EC, MoH and to the 
regulatory authorities of the study site according to the local legal requirements in 7 
days. 
Serious Adverse Events which occurred within two weeks after termination of the 
clinical trial and which are considered to be related to the trial must also be reported. 
Any Adverse Event which is not resolved at the final visit should be followed-up until 
it will be resolved or assessed as a stable condition or causality other than the trial 
medication has been found.

16.2. Case Report Form (CRF) 
NOVAGENIX will design the Case Report Form in close co-operation with the 
Sponsor. Standardized CRFs will be used as source document regarding volunteers' 
raw data during the course of the study. The investigator will assure that all data are 
entered promptly, legibly, completely, accurately and in accordance with other source 
documents (e.g. ECGs, laboratory results, diet and fluid intake records). This 
procedure will be applied to the data of both volunteers who met the inclusion 
criterion and will be included into the study and the volunteers that will not be 
included into the study because of a valid reason.  
To ensure legibility, the CRFs should be filled out only with a blue ball-point. 
Any corrections to the CRFs must be carried out by the investigator or his designate. A 
single stroke must be drawn through the original entry. The reason for the correction 
has to be given and it has to be dated and initialled. Incorrect entries must not be 
covered with correcting fluid, or obliterated, or made illegible in any way. 
Even if there are no changes from a previous examination, in the interests of 
completeness of data acquisition, the questions which are repeated in each section of 
the CRFs should be answered in full text. A reasonable explanation must be given by 
the investigator for all missing data. 
The CRFs will be completed immediately after termination of the individual treatment 
and observation periods and the final examination. After being signed by the 
investigator, they will be sent to NOVAGENIX for data validation. Thereafter, CRFs 
will be returned to NOVAGENIX and eventually forwarded to the Investigator for 
final corrections, if applicable. CRFs can not be sent by post but only be personally 
submitted to the NOVAGENIX monitor during a visit or sent by courier. Any other 
way of transport is to be previously discussed with the NOVAGENIX. NOVAGENIX 
will send the original CRFs to Sponsor with the final report of the study. 
NOVAGENIX will store the copy of all CRFs. 
All medical records upon which the CRFs are based must be kept for at least 14 years 
after completion of the study. At this time ALPAN Farma will discuss with the 
Sponsor whether or not storage is required for a longer period. Image carriers or other 
data carriers can be used for the purpose of storage.

17.  ANALYTICAL EVALUATION  
Plasma concentrations of favipiravir will be determined by means of a validated LC 
method, according to Novagenix’s SOP NOV-ENG-08-TEC1.  
Detailed characteristics of the analytical method applied will be described in the 
“Analytical Study Plan” (see Appendix III: Analytical Study Plan). All assay 
validations will be performed in consideration of the Guideline on Bioanalytical Method 
Validation,EMA,21 July 2011 and  US FDA Guidance for Industry, Bionalytical Method 
Validation May 2018 or current guidance on method validation date. 
Volunteer’s all samples will be measured in a single analytical run in order to 
eliminate the influence of the inter-assay variance on the assessment. The analyst has 
to provide a final analytical report with tables for all samples that were analysed. 
Already measured samples will be stored at <-20°C for at least 6 months (storage 
period can be prolonged in exceptional cases, e.g. upon special request of authorities) 
after termination of bio-analysis. At that point a further decision by the Sponsor will 
be taken. 
20% of the chromatograms are to be included in printed Final Study Report. But 100 
% of chromatograms will be given also as electronically. 
 
17.1. Reanalysis of study samples 
The reasons for reanalysis of study samples are presented in Appendix III: Analytical 
Study Plan. 
 
17.2. Incurred Sample Reanalysis 
Incurred Sample Reanalysis (ISR) will be performed at any time after starting subject 
analysis by choosing two sampling points near or at Cmax and two sampling points in 
the elimination phase per period (total 8 sampling points per subject). These ISR 
points will be selected according to the literatures and/or  in the very first batches of 
subject analysis. The subjects will be randomly selected and the number of subjects 
that defined as ISR points will be equal or more than 10% of samples for the first 1000 
study samples and an additional 5% of samples for study samples in excess of 1000. 
The difference between the study samples’ and incurred samples’ values obtained 
should be within 20% of the mean for at least 67% of the repeats according to 
EMEA/CHMP/EWP/192217/2009 Rev.1 Corr.2. Guideline on  Bioanalytical Method 
Validation. London, 21 July 2011, p.13-14;  Novagenix's SOP-NOV-ENG-08-CQU4 
and documented in the Final Study Report.

18.  PHARMACOKINETIC EVALUATION 
Pharmacokinetic parameters of favipiravir will be determined using non-
compartmental methods from measured plasma concentrations. 
For each treatment (Test Drug or Reference Drug) and each volunteer participating 
completely in this single-dose, two period, cross-over study the following 
pharmacokinetic parameters will be calculated:  
Primary pharmacokinetic parameters: 
Cmax: Maximum observed plasma concentration 
AUC0-tlast: Area under the plasma concentration-time curve from zero to the last 
measurable concentration, calculated by the linear log trapezoidal rule. 
Secondary pharmacokinetic parameters: 
AUC0-∞: Area under the plasma concentration-time curve, calculated by extrapolation 
to infinity. 
tmax: Time to maximum observed plasma concentration 
t1/2 :  Terminal half-life 
Additional pharmacokinetic parameters: 
MRT:  Mean residence time 
λz: Terminal rate constant. 
For pharmacokinetic calculations, the program package Phoenix WinNonlin (Version 
8.1, Certara L.P.) or above will be employed. Phoenix WinNonlin will also be used to 
generate concentration/time plots.

19. STATISTICAL PROCEDURES 
The statistical analysis of the pharmacokinetic data described in this section 
corresponds with provisions according to the EMA guideline for bioequivalence (Doc. 
Ref.: CPMP/EWP/QWP/1401/98 Rev. 1/ Corr **)- 2010. 
Statistical analysis will be performed as a valid case analysis including all volunteers 
in which no major protocol deviations occurred and all primary target variables are 
available for measurement.  
If a volunteer is to be excluded from evaluation, this decision has to be justified in the 
Final Study Report. Statistical analysis will be performed by means of the program 
Phoenix WinNonlin (Version 8.1, Certara L.P.) or above. 
 
 
19.1. Target Variables 
19.1.1. Primary Target Variables 
Cmax and AUC0-tlast are declared to be primary target variables.  
 
19.1.2. Secondary Target Variables 
AUC0-, tmax and t1/2 are declared to be secondary target variables. MRT and z   will 
be determined also. 
In order to achieve a better approximation to a normal distribution Cmax and AUCs data 
will be logarithmically transformed (base e) before analysis. The sources of variation 
will be treatments, periods, sequence and subjects (nested within sequence) in 
Analysis of variance (ANOVA). Evaluation of treatment, period, sequence and subject 
(nested within sequence) effects at 5% level of significance will be performed. From 
the result of this procedure, the two one-sided hypothesis at the 5% level of 
significance will be tested by constructing the 90% confidence interval for the 
geometric mean ratios test/reference products. The confidence interval is calculated by 
retransformation of the shortest confidence interval for the difference of the ln-
transformed mean values. Differences in tmax will be evaluated non-parametrically. 
Bioequivalence will be concluded if the 90% confidence intervals for the geometric 
mean ratios of the products (test/reference) are fully contained within the limits of 
acceptance of 80% - 125% for Cmax and AUC0-tlast. For the secondary target variables, 
the 90% confidence intervals will be investigated for exploratory purposes. 
Evaluating excluding values from statistical calculations, the criteria which are given 
in “Novagenix SOP-NOV-ENG-08-CQU5” will be applied. 
These criteria are; 
 If a suspicious case about safety of blood samples such as in the absence of label,  label is not read 
exactly or any confusion of sample, these samples are documented on “Protocol For Handing Over 
Receipt of Samples” form. These samples are analysed but not included in statistics. 
 
 After completing study analysis, reanalysis is done due to analytical reason according to SOP-NOV-
ENG-08-TEC1 and SOP-NOV-ENG-08-CQU4. If the reanalysed data is still invalid for the analytical 
reason and there is insufficient plasma sample for reanalysis, that data should be excluded from 
statistical analyses. Any exclusion should be properly reported on final study report.

 A subject with lack of any measurable concentrations or only very low plasma concentrations for 
reference medicinal product. A subject is considered to have very low plasma concentrations if its AUC 
is less than 5% of reference medicinal product geometric mean AUC (which should be calculated 
without inclusion of data from the outlying subject). That subject will be evaluated and may be 
excluded. Accordingly the two results are reported in final study report. 
 
 Subjects with non-zero baseline concentrations > 5% of Cmax. Such subject should be excluded from 
statistical calculation. 
 
 Total number of subject should not be under 12 in the statistical calculation, whether not this study 
would be repeated from the clinic part. 
19.1.3. Safety Evaluation 
The assessment of safety will be based mainly on the frequency of AEs and on the 
number of  laboratory values that fall outside of pre-determined ranges. Other safety 
data (e.g. electrocardiogram, vital signs and special tests) will be considered as 
appropriate. 
19.2. Calculation of Sample Size 
The intra-individual variability of Cmax is estimated as 17% according to only one 
literature. Since there is insufficient information for intra-individual variability, sample 
size has been choosen as 30 subjects in order to demonstrate bioequivalence for a 2x2 
crossover design. 
19.3. Randomisation 
The randomisation table will be provided by Novagenix. 30 subjects, who will be 
included in the study, will be determined to receive either Test or Reference Product 
[In each study period, subjects will take different products (one dose of Test Drug or 
one dose of Reference Drug)] by a randomisation table. 
30 subjects, who will be included in the study, will be determined to receive either 
Treatment A or Treatment B in Period I and Period II by a randomisation table 
generated by a computer programme. Which one of the Test or Reference 
administration will be Treatment A or Treatment B is randomised by the Investigator. 
All the analytical analyses are done without the knowledge of the Test and the 
Reference product. These products will be named and known as Treatment A or 
Treatment B by CRO. Then the form defining Treatment-Period relationship will be 
enveloped, sealed and sent to CRO by the Investigator. CRO will open the sealed 
envelope in the “Project Evaluation Meeting” which will be held after the laboratory 
analyses are completed. Once the seal is opened, no new reanalyse or no data 
change/exclusion will be allowed. 
 
19.4. Documentation of the Data 
Measured plasma concentrations will be listed per treatment for each volunteer and 
each sampling point. In addition, mean values, standard deviations and the standard 
error of the mean will be given per sampling point of each treatment. 

Study Code: NOV2020/01917

For all pharmacokinetic parameters determined, the individual values per treatment 
will be tabulated with descriptive statistics (i.e. calculation of arithmetic means, 
standard deviation and standard error of the mean, geometric means, minimum, 
maximum, median and the number of evaluated values). 
To display the time course of the plasma concentrations, individual concentration time 
curves as well as mean curves for each formulation will be plotted both in the linear 
and loglinear scale, using Phoenix WinNonlin (Version 8.1, Certara L.P.)  or above. 
All results will be summarized in tables and plots and will be reported and discussed in 
the Final Study Report. 
Descriptive analysis of demographic and safety data reported in the CRFs will be 
included in the Clinical Raw Data. 
19.5. Interim Evaluation 
No interim evaluation is planned in the present trial.

21.2. Preventive Measures to Reduce Bias 
The following measures are incorporated into the study in order to minimize bias: 
 Volunteers are sequentially assigned to randomly ordered treatments, 
 Volunteer enrollment is dependent on satisfactory fulfilment of the given list of 
inclusion criteria, 
 The circumstances when individual volunteers withdraw prior to planned 
completion of the study are specified. 
21.3. Investigator's Obligations 
Prior to initiation of this study, the investigator will approve this protocol by signing 
the signature page. This signature confirms that the study will be performed in 
compliance with the protocol. The investigator must ensure that the Sponsor or the 
ALPAN Farma provides adequate documents (i.e. Product Information) giving 
information about the pharmacological and toxicological properties of the test product. 
The investigator or his medically educated representative will review the CRFs for 
completeness and accuracy. The investigator will sign and date the CRFs and any 
changes in the CRF. 
The signatures serve to attest that the information contained in the CRFs is true and 
has not been falsified. In case of a correction the reason for it shall also be given. It is 
the investigator's responsibility to assure completion of entries and to review and 
approve all CRFs. At all times the investigator has the final responsibility for the 
accuracy and authenticity of all clinical and laboratory data entered in the CRFs 
(section 16.2). 
21.4. Adherence to the Protocol 
Protocol violations are any deviations from the procedures outlined in this document, 
missing evaluations, incorrect timing of evaluations, non-compliance with study 
procedures and intake of prohibited medications. 
After a volunteer has been enrolled, it is the investigator's responsibility to make a 
reasonable effort to avoid any protocol violations and to keep the subject in the study.  
All protocol violations will be reported immediately to the Sponsor during the course 
of the study. The nature of these violations will be defined in written form. All 
protocol deviations will be listed and will be discussed with the Sponsor prior to the 
statistical analysis. 
The investigator undertakes all reasonable measures to record data in adherence with 
the protocol. Under practical working conditions, however, some minor variations may 
occur due to circumstances beyond the control of the investigator. All such deviations 
will be documented on the project records, together with the reason for their 
occurrence, and where appropriate, detailed in the study report.

21.5. Data Handling Procedures 
The results from screening and data collected during the study will be recorded in the 
volunteer's Case Report Form (CRF) which will be designed and printed by 
NOVAGENIX. Each volunteer receives a code number. His personal identification 
remains in a separate confidential file that can be used only together with the 
investigator. Each CRF will be signed and dated by the investigator. All corrections in 
the CRFs are to be made legibly and signed by the investigator. 
The investigator is responsible for the transfer of CRF and other required documents to 
ALPAN Farma. All CRFs are thereafter delivered to ALPAN Farma. Copies of all 
CRFs will be sent to NOVAGENIX by ALPAN Farma for Final Study Report writing.  
In order to maintain volunteer confidentiality, all data recorded during the course of 
the study will only be identified by volunteer initials and volunteer study number. 
However, the investigator agrees to record the complete volunteer identification on the 
volunteer identification list. This list will be treated with strict adherence to 
confidentiality and will be filed in the Investigator's File. 
21.6. Monitoring 
It is the responsibility of the investigator to assure that the study is conducted in 
accordance with the protocol and that valid data are entered into the CRF. 
Monitoring and auditing of this study will be performed by Sponsor’s authorized 
personnel in order to check the adherence to the protocol in compliance with Good 
Clinical Practice guidelines and to ensure international acceptability of the study data. 
In support of these measures, the investigator will make the records available to 
ALPAN Farma or to the Sponsor upon request at reasonable times. Case report 
forms will be checked for completeness and clarity. 
Data verification is legally required and will be done by direct comparison with source 
documents in case of volunteer's respective consent with data on CRFs or by cross-
checking with source documents in the presence of the investigator - always giving 
due consideration to data protection and medical confidentiality.  
The investigator will permit a representative of Sponsor to monitor the study as 
frequently as necessary to determine that data recording and protocol adherence are 
satisfactory. The CRFs and related documents will be reviewed in detail in accordance 
with the Sponsor and Good Clinical Practice regulations. 
Monitoring of this study will be performed by Sponsor’s authorized personnel at 
suitable intervals throughout the study. These visits will be for the purpose of verifying 
adherence to the protocol and the completeness and exactness of the data entered on 
the Case Report Forms. The Sponsor is allowed to get any information about the state 
of the study. Case Report Forms will be transported from the investigator via ALPAN 
Farma to the Sponsor after completion of the trial. 
It is the investigator's obligation to assure documentation of all relevant data in the 
volunteer's file, such as medical history / concomitant diseases, date of study 
enrolment, visit dates, results of examinations, administrations of medication and 
adverse events. 

Study Code: NOV2020/01917

The investigator will affirm and uphold the principle of the subject's right to protection 
against the invasion of privacy. Throughout the study, all data will only be identified 
by volunteer number and volunteer initials. The data will be blinded correspondingly 
in all data analyses. 
After completion of the study, all unused study medication and empty sachets will be 
collected by the ALPAN Farma and returned to the Sponsor. 
21.7. Auditing 
In order to guarantee that the performance of the study is in accordance with the GCP 
provisions, in-house and, if needed, on-site audits may be carried out. The auditor will 
be independent from the staff involved in the proceedings of this clinical study. 
The investigator agrees to give the auditor access to all relevant documents for review. 
The same applies in case of an inspection of local or national authorities. In  case of 
any inspection of FARMAGEN-Good Clinical Practice and Research Center by an 
outside authority, the Sponsor will be consulted before the Inspectors are permitted 
access to any of the project records. 
After every on-site audit the investigator will receive an audit confirmation by the 
auditor. This has to be filed together with the study documentation and be made 
available to the local authorities in case of inspection. At the end of the study, an audit 
certificate will be included in the final report. 
The NOVAGENIX Quality Assurance Unit (QAU) may conduct an inspection of the 
study procedures. The findings will be reported to the CRO Project Responsible. 
21.8. Confidentiality 
Volunteers will be informed that all study findings will be stored on computer and 
handled strictly confidential. Volunteers will be identified throughout documentation 
and evaluation by the individual volunteer number only, whereas all volunteer names 
will be kept secret by the investigator. 
All information concerning study medication, all study materials and study drugs shall 
remain the property of the Sponsor. NOVAGENIX and the investigator are obliged to 
keep all data and information of the study confidential and to use those data only after 
permission of the Sponsor. It is understood that no study material or information 
developed in this trial in connection with Favicovir 200 mg Film Tablet by the 
Sponsor shall be made available to third parties, except for official representatives 
such as Regulatory Authorities.  
21.9. Insurance 
The volunteers will be insured by ALPAN Farma in accordance with the requirements 
and regulations for participants in a clinical trial. This insurance is taken out with 
Mapfre Sigorta A.Ş.  
A copy of the Insurance Certificate for this study is included in Appendix V of this 
protocol.

It will be paid by ALPAN Farma to the volunteers who will participate the clinical 
phase of the study for  the loss of their working days and their expenditure during and 
for the trial (e.g. transportation, communication, meal, accommodation, etc.). The 
amount is determined in the Budget Form in the EC and MoH submission files. 
21.11 Qualification of the Investigator 
By his signature of the study protocol, the investigator certifies that she/he has more 
than 5 years experience in the conduction of clinical trials. A signed and dated CV of 
the investigator containing this information will be submitted in Appendix VI of this 
study protocol.

22. PROTOCOL AMENDMENTS 
22.1. Protocol Modifications 
In order to ensure most comparable conditions during all phases of the trial and in the 
interests of valid statistical analysis neither the investigator nor NOVAGENIX or the 
Sponsor will alter the study conditions agreed upon and set out in this protocol. 
Amendments should be made only in exceptional cases and by mutual agreement 
between the investigator, NOVAGENIX, ALPAN Farma and the Sponsor. Any 
amendment must be set out in writing, at the same time giving the reasons, and signed 
by all parties concerned. The amendment then becomes part of the study protocol. 
Amendments which might have an impact on the safety and well-being of the subject 
such as the use of additional invasive examination methods require a new vote by the 
EC and MoH and a further Informed Consent Form that is to be signed by all subjects 
enrolled in the trial who are affected by the amendment. Other changes will only be 
submitted to the EC and MoH in a written form. 
The investigator may implement a deviation from, or a change of the protocol to 
eliminate an immediate hazard(s) to trial subjects without prior EC and MoH approval 
opinion. As soon as possible, the implemented deviation or change, the reason for it, 
and if appropriate, the proposed protocol amendment(s) should be submitted: 
(a)  
to the EC and MoH  for review and approval opinion, 
(b)  
to the Sponsor for agreement and if required, 
(c)  
to the regulatory authority(ies). 
The investigator should not implement any deviation from, or changes of the protocol 
without agreement by the Sponsor and prior review and documented approval opinion 
from EC and MoH of an amendment, except where necessary to eliminate an 
immediate hazard(s) to volunteers, or when the change(s) involves only logistical or 
administrative aspects of the trial (e.g., change in monitor(s), change of telephone 
number(s)). 
If the approval by an EC and MoH is required for amendments, this must also be 
sought. 
22.2. Protocol Violations 
Protocol violations are major deviations from the procedures outlined in this document 
like missing evaluations, incorrect timing of evaluations, non-compliance with study 
medication and intake of prohibited medications. After a subject has been enrolled, it 
is the investigator's responsibility to make a reasonable effort to correct any protocol 
violations and to keep the subject in the study.

23. REPORTS 
Prior to issuing the Final Study Report, NOVAGENIX will prepare a draft report 
according to the ICH guideline for approval by sponsor. The draft report will be 
submitted for a Quality Assurance audit and any findings or notifications will be 
appropriately considered in the final version. NOVAGENIX will prepare one Final 
Study Report with original signatures and send to sponsor both in paper and as CDs. 
 
23.1. Archiving 
ALPAN Farma will store all essential documents (i.e. original CRFs, Clinical Study  
Protocol, audit certificates, all written statements concerning the study etc.) and the 
Final Study Report at least 14 years. 
The investigator will keep the volunteer files and original data as long as possible and 
according to the local methods and facilities. The investigator should maintain the trial 
documents as specified in the ICH-GCP guideline (essential documents). The 
investigator must take measures to prevent accidental or premature destruction of these 
documents. Essential documents should be retained for at least 14 years after the 
completion of study. The subject identification codes list and subject's signed informed 
consent will be archived for at least 14 years. 
These documents should be retained for a longer period, however, if required by the 
applicable regulatory requirements or by an agreement with the Sponsor. It is the 
responsibility of the Sponsor to inform the investigator when there is no further need 
to retain these documents.  
Documents of a terminated study have to be archived accordingly at least 14 years 
after termination of the study. 
In case of any change concerning the archiving procedures the investigator/institution 
has to inform the Sponsor immediately.
