BACKGROUND
Diabetic peripheral neuropathy (DPN) is one of the most commonly encountered 
neuropathic pain syndromes in clinical practice, and is a particularly debilitating
complication of diabetes.  According to both the American Diabetes Association and 
the National Institute of Diabetes and Digestive and Kidney Disease, 60 to 70 
percent of diabetics will eventually develop some form of diabetic neuropathy.  
Today, it is estimated that 3 to 6 million patients with diabetes have painful DPN.1,2  
The total annual cost of DPN and its complications in the U.S. is estimated to be 
between $4.6 and $13.7 billion.3-5   
Currently, there are only three drugs approved by FDA specifically for the treatment 
of the symptoms of DPN: Nucynta ER – (tapentadol), an opioid medication; 
Cymbalta – (duloxetine), a serotonin and norepinephrine reuptake inhibitor; and 
Lyrica – (pregabalin), an anticonvulsant drug.  All are prescribed for the 
management of pain associated with diabetic peripheral neuropathy.   
Hepatocyte growth factor (HGF) has been shown to be a potent angiogenic growth 
factor, stimulating the growth of endothelial cells and migration of vascular smooth 
muscle cells.6,7  Recent research also indicates that HGF can function as a 
neurotrophic factor.8  It is proposed that administration of HGF may promote axonal 
growth and regeneration.  As loss of microvasculature in diabetic neuropathy has 
also been implicated in acceleration of neuronal loss and pain symptoms,9 HGF may 
be an ideally suited candidate for the treatment this condition.  
VM202 is a DNA plasmid that contains novel genomic cDNA hybrid human 
hepatocyte growth factor (HGF) coding sequence 
 expressing two 
isoforms of HGF, 
.  VM202 has been used in phase I and II 
studies for painful diabetic peripheral neuropathy (PDPN) with significant efficacy 
on pain.   
In the phase III VMDN-003 study, subjects received 2 treatments of either VM202 
or placebo administered as intramuscular (IM) injections into bilateral calves on 
Days 0 and 14, and Days 90 and 104.  Primary efficacy was evaluated 90 days 
following the first injection.  The growth potential for HGF make long-term follow-
up important both for safety and efficacy: in order for VM202 to be a candidate for 
chronic treatment of PDPN, it must be demonstrated not to induce unexpected 
adverse events with repeated dosing; and the potential for reversal or stabilization of 
diabetic neuropathy using only one or two treatments of VM202 may make it 
especially attractive compared to current treatments which must be taken daily for 
the duration of the disease.  A safety extension to the VMDN-003 study is therefore 
warranted.

EXAMINATIONS AND EVALUATIONS
4.1. 
CONCOMITANT MEDICATIONS 
All concomitant medications (taken since completion of Day 270 of the VMDN-003 
study) will be recorded at each study visit.  For each medication taken, the following 
information will be collected: 
•
Medication trade name;
•
Indication for which the medication was given;
•
Dose/strength, route, and frequency of administration;
•
Date started and date stopped (or continuation at study exit).
4.2. 
VITAL SIGNS 
Vital signs consisting of blood pressure (while subject is sitting), temperature, 
weight, heart rate, and respiratory rate will be measured and recorded. 
4.3. 
DAILY PAIN AND SLEEP INTERFERENCE DIARY 
Subjects will be asked to keep a Daily Pain and Sleep Interference Diary (see 
Appendix 2).  Subjects will be asked to rate their 24-hour average daily pain 
intensity score using an 11-point numerical rating scale from 0 (no pain) to 10 (worst 
possible pain).  The effect of pain on the subject’s ability to sleep will be assessed 

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 17 of 45 
using the sleep interference score.  Like the pain intensity score, the sleep 
interference score is an 11-point numerical rating scale from 0 (pain did not interfere 
with sleep) to 10 (pain completely interfered; subject was not able to sleep due to 
pain).   
The diary will be completed within 14 days prior to the Day 365 visit.   To increase 
compliance, the Diary will be FedExed to the subject 2 weeks prior to the scheduled 
visit.  The FedEx shipping bill will become part of the subject’s source documents.  
Ten days prior to the scheduled visit, the study coordinator will call the subject to 
remind the subject of their upcoming visit at Day 365, and the requirement to 
complete the diary starting within 14 days of the visit.  The phone call will be 
documented on the source document worksheets.  One day prior to the visit, the site 
study coordinator will call the subjects to confirm their upcoming visit and to remind 
the subject to bring the completed Diary.  If the subject arrives at the clinic without 
the completed diary, the visit will be rescheduled as soon as possible.   
Upon completion of the Diary, the study coordinator will check the Diary for 
completeness.  Any omissions or ambiguous answers will be clarified by the subject 
prior to leaving the clinic.  Note, the subject will be required to initial each page of 
the diary. 
4.4. 
PATIENT’S GLOBAL IMPRESSION OF CHANGE (PGIC) 
The patient’s global impression of change after treatment will be measured using the 
Patient’s Global Impression of Change (PGIC) questionnaire.10  This questionnaire 
measures a patient’s perception of how treatment has affected their level of activity, 
symptoms, emotions, and overall quality of life.  Each descriptor is ranked on an 
intensity scale of 1 = Very Much Improved; 2 = Much Improved; 3 = Minimally 
Improved; 4 = No Change; 5 = Minimally Worse; 6 = Much Worse 7 = Very Much 
Worse.  This test will be self-administered during study visits on Day 365.   
Upon completion of the questionnaire, the study coordinator will check the 
questionnaire for completeness.  Any omissions or ambiguous answers will be 
clarified by the subject prior to leaving the clinic.  The PGIC can be found in 
Appendix 3.  Note, the subject will be required to initial and date the PGIC. 
5.
EVALUATION OF ADVERSE EVENTS
5.1. 
DEFINITIONS 
An Adverse Event (AE) is the development of an untoward medical occurrence or 
the deterioration of a pre-existing medical condition following or during exposure to 
an investigational product, whether or not considered causally related to the product.  
An untoward medical condition can be symptoms (e.g., nausea, chest pain), signs 
(e.g., tachycardia, enlarged liver) or clinically significant abnormal results of an 
investigation (e.g., laboratory findings, electrocardiogram). 

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 18 of 45 
Conditions or diseases that are chronic but stable should not be recorded as an AE.  
Changes in a chronic condition or disease that are consistent with natural disease 
progression are NOT considered AEs and also should not be recorded on AE 
worksheets.  These medical conditions should be adequately documented on the 
appropriate page of the study worksheet (relevant medical history and/or physical 
examination).  However, medical conditions present at enrollment that worsen in 
intensity or frequency in a manner inconsistent with the natural course of the disease 
during the treatment or post-treatment periods should be reported and recorded as AEs. 
An adverse reaction means any adverse event caused by a drug.  Adverse reactions 
are a subset of all suspected adverse reactions for which there is reason to conclude 
that the drug caused the event. 
Suspected adverse reaction means any adverse event for which there is a 
reasonable possibility that the drug caused the adverse event.  For the purposes of 
IND safety reporting, ‘reasonable possibility’ means there is evidence to suggest a 
causal relationship between the drug and the adverse event. A suspected adverse 
reaction implies a lesser degree of certainty about causality than adverse reaction, 
which means any adverse event caused by a drug. 
A serious adverse event (SAE) is any untoward medical occurrence which: 
•
Results in death;
•
Is life-threatening;
•
Requires inpatient hospitalization (admission to hospital with a stay > 24 hours)
or prolongation of hospitalization which is not specifically required by the
protocol or is elective;
•
Results in permanent impairment of a body function or permanent damage to a
body structure; or
•
Requires medical or surgical intervention to preclude permanent impairment of a
body function or permanent damage to a body structure.
Additionally, important medical events that may not result in death, be life-
threatening or require hospitalization may be considered SAEs when they jeopardize 
the subject or require medical or surgical intervention to prevent one of the serious 
outcomes listed above.  Examples of such medical events include: allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient hospitalization or the 
development of drug dependency or drug abuse.  Medical and scientific judgment 
must be exercised when classifying events as serious. 
Life-threatening means that the subject is, in the view of the investigator, at 
immediate risk of death from the AE as it occurred.  It does not include an AE 
which, had it occurred in a more serious form, might have caused death.   

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 19 of 45 
Persistent or significant disability/incapacity means that the event resulted in 
permanent or significant and substantial disruption of the subjects’ ability to carry 
out normal life functions.   
An unexpected AE is an AE, the nature or severity of which is not consistent with 
the applicable product information (e.g., Investigator Brochure for an unapproved 
product).  Expected means that the event has been previously observed with the test 
article and is identified and/or described in the applicable product information.  It 
does not mean that the event is expected with the underlying disease(s) or 
concomitant medications.  It is expected that certain disease states will have 
reoccurring adverse events some of which may be considered expected over time. 
5.2. 
ASSESSMENT OF AES 
All AEs, regardless of severity, occurring following study drug administration by a 
subject must be recorded on the AE worksheet.  This will include the following 
information: 
•
Description of the AE
•
Date of onset
•
Duration
•
Frequency
•
Severity
•
Seriousness (yes/no)
•
Treatment
•
Outcome
•
Relationship to study medication, injection procedure and/or underlying disease
All AEs and SAEs must be followed until resolution, or the condition stabilizes.  The 
Investigator is responsible to ensure that follow-up includes any supplemental 
investigations as may be indicated to elucidate as completely as possible the nature 
and/or causality of the AE or SAE.  This may include additional laboratory tests or 
investigations, histopathological examinations, or consultation with other health care 
professionals.  The Sponsor or its designee may request that the Investigator perform 
or arrange for the conduct of supplemental measurements and/or evaluations. 
5.2.1. 
AE CAUSALITY 
The study investigator will determine whether an AE is related or unrelated to study 
medication, the procedure (intramuscular injection) and / or the underlying disease 
using the following criteria: 
Not related: An adverse event that is not related to the use of the test article or 
administration procedure.   
Possibly related: An adverse event that might be due to the use of the test article or 
administration procedure.  An alternative explanation, e.g., concomitant study 

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 20 of 45 
product(s), concomitant disease(s), is inconclusive.  The relationship in time is 
reasonable; therefore, a causal relationship cannot be excluded.   
Probably related: An adverse event that might be due to the use of the test article or 
administration procedure.  The relationship in time is suggestive.  An alternative 
explanation is less likely, e.g., concomitant drug(s), concomitant disease(s). 
Definitely related: An AE that is due to the use of the test article or administration 
procedure.  The event cannot be reasonably explained by an alternative explanation – 
e.g., concomitant drug(s), concomitant disease(s).
5.2.2. 
AE INTENSITY 
The intensity of the AE/SAE will be defined by the following criteria: 
Mild: 
The AE is noticeable to the subject but does not interfere with 
routine activity. 
Moderate: 
The AE is discomforting and interferes with routine activity. 
Severe: 
The AE significantly limits the subject’s ability to perform 
routine activities despite symptomatic therapy. 
5.3. 
REPORTING/RECORDING OF AES 
Throughout the course of the study, all efforts will be made by the investigator to 
remain alert to possible AEs.  The first concern will be the safety of the subject, and 
for providing appropriate medical intervention.  The period of observation for 
collection of AEs starts during the first intramuscular injection procedure (Day 0) 
until the Day 365 follow-up safety extension visit.  Any AE should be recorded on 
the appropriate study worksheet. 
5.4. 
REPORTING / RECORDING OF SAES 
5.4.1. 
INVESTIGATOR’S RESPONSIBILITY 
SAEs will be recorded following the first study drug administration through the Day 
365 safety extension follow-up visit.  Any serious adverse event or unexpected 
adverse event that occurs during this investigation, whether or not related to the 
study medication, must be reported as soon as possible but no later than 3 working 
days after the investigator first learns of the event to the Sponsor and the designated 
CRO by completing the SAE form and the AE information in the EDC and selecting 
appropriate criteria that classifies the AE as serious and/or unexpected.  In order to 
have the Investigator’s signature on file, the signed SAE form needs to be uploaded 
to the EDC at the time of initial data entry.    
Each SAE must be followed with appropriate medical management until resolved or 
assessed as chronic or stable regardless of whether or not, in the opinion of the 
Investigator, the event is thought to be related to the study medication.   

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 21 of 45 
The Investigator will be required to provide complete information (including the 
Investigator’s opinion of the relationship of the SAE to the study medication) 
concerning each SAE to the CRO and Sponsor within 5 working days of first 
learning of the event.  This information must be recorded in the subject’s medical 
record and then entered into the EDC.  Copies of related source documentation such 
as results/reports, hospitalization records, and other relevant information must be 
obtained if possible. 
In the event of an SAE leading to hospitalization, every effort will be made by the 
investigational site to obtain medical records, including a hospital discharge 
summary.  In the event of a fatal AE, documentation of any available postmortem 
findings, including autopsy, will be provided to the Sponsor or their designee.  In 
any event, the Investigator will provide a narrative summary of circumstances, 
events related to the death, and cause of death, if known.   
The Investigator must comply with the applicable local regulatory requirements 
related to the reporting of SAEs to regulatory authorities and the Institutional 
Review Board (IRB), and Institutional Biosafety Committee (IBC) if applicable.  
Upon receipt from the Sponsor of an initial or follow-up IND Safety Report or other 
safety information, the Investigator must promptly notify his or her IRB, and IBC (if 
applicable). 
5.4.2. 
SPONSOR’S RESPONSIBILITY 
All AEs and SAEs will be reported on an annual basis to FDA in accordance with 
the IND regulation (21 CFR Part 312).  Per the 2010 FDA Guidance Document for 
Industry and Investigators “Safety Reporting Requirements for INDs and BA/BE 
Studies,” events categorized as ‘possibly’ or ‘probably’ related will be treated as 
‘suspected adverse reactions.’  Events categorized as ‘definitely’ related will be 
treated as an ‘adverse reaction.’ 
All serious, unexpected adverse reactions and suspected adverse reactions will be 
reported to FDA and to all participating investigators as an IND Safety Report 
within 15 calendar days of the event after the sponsor determines that the suspected 
adverse reaction qualifies for reporting (21 CFR §312.32).  Any unexpected fatal or 
life-threatening AEs will be reported to the Agency within 7 calendar days after the 
sponsor’s initial receipt of the information. 
The Sponsor will notify all participating investigators of any new safety information 
that alters the current risk-benefit assessment of the study medication or that would 
be sufficient to consider changes in VM202 administration or in the overall conduct 
of the trial. 
5.5. 
ANALYSIS POPULATION 
The analysis population will be the safety population, and will include all subjects 
who sign consent for the safety extension study.  Subjects in the analysis population 

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 22 of 45 
will be analyzed according to treatment received, regardless of original treatment 
assignment.  The primary analyses of the primary and secondary endpoints will be 
based on the analysis population. 
5.6. 
STUDY ENDPOINTS 
5.6.1. 
PRIMARY ENDPOINTS 
The primary endpoint is the difference in long-term safety – defined as occurrence of 
adverse events -  observed between subjects receiving VM202 versus subjects 
receiving placebo in the VMDN-003 study. 
5.6.2. 
SECONDARY ENDPOINTS 
The secondary efficacy endpoints are: 
1.
The change in the average 24-hour pain score from baseline to the Day 365
follow-up from the Daily Pain and Sleep Interference Diary;
2.
The change in the average 24-hour pain score from Day 270 to the Day 365
follow-up from the Daily Pain and Sleep Interference Diary; and
3.
Patient’s Global Impression of Change (PGIC) at the Day 365 follow-up.
5.6.3. 
ANALYSIS METHODS 
The statistical analyses will be descriptive only and reported using summary tables, 
figures, and listings.  All summaries will be derived based on available data.  The 
average 24-hour pain score for a visit will be considered as missing if fewer than 5 of 
7 days of Daily Pain and Sleep Interference Diary entries are provided.  No 
imputation will be performed for missing values.  Summary tables will present 
results by treatment group (i.e., VM202 and Placebo) both within and across the 
randomization stratification factor (i.e., baseline use of gabapentin and/or pregabalin) 
values.  Continuous variables will be summarized using the number of non-missing 
values, mean, standard deviation, median, minimum and maximum values.  
Categorical data will be summarized using the number of observations and 
percentages.  Summary plots of efficacy data will present mean values with standard 
error bars.   
5.6.4. 
DATA SAFETY MONITORING BOARD (DSMB) 
The independent data safety monitoring board (DSMB) for the VMDN-003 study 
will periodically review a limited set of un-blinded tables and/or listings, including 
all reported AEs, as per its responsibilities described in the DSMB Charter.  The 
objectives of the DSMB meetings are to review the safety outcomes of the study and 
provide guidance to study sponsor regarding the safety of the VM202.  The data 
analyses for the DSMB meetings will be provided to the DSMB members and other 
participants of the DSMB meeting.

ACCESS TO STUDY DOCUMENTS AND STUDY MONITORING
The Sponsor has designated consultants to monitor the progress of this study.  The clinical 
monitor, as a representative of the Sponsor, has the obligation to follow this study closely.  
The Sponsor or its designee may meet with investigators prior to the initiation of the study 
in order to review the adequacy of the subject population, facilities, and equipment with 
respect to the needs of the study, and to familiarize the investigator with the study protocol.  
The Sponsor or its designee may meet with the investigator(s) at the time study subjects 
begin to be enrolled in order to ensure that subjects are being properly selected and that 
study data are being correctly recorded.   
During the study, the clinical monitor will visit the study facilities regularly, and utilize 
telephone and written communications on an ongoing basis to maintain current knowledge 
of the study.  During periodic visits to the study site, the monitor will review the study 
worksheets used for data entry in the EDC system to verify the accuracy and completeness 
of the information contained in those reports in preparation for retrieval.  Study worksheets 
and source documents must contain all data entered in the EDC system.  All data generated 
during this study and the study worksheets/source documents from which they originated 
are subject to inspection by the Sponsor or its representatives, the FDA and other 
regulatory agencies. 
Upon completion of the study, the clinical monitor will conduct a final visit (close-out) to 
the site.  The objectives of this visit are to ascertain that all regulatory records and reports 
are complete, verify that study drug and other supplies have been accounted for and ensure 
that the investigator is aware of his/her responsibilities post-study. 
7.
QUALITY CONTROL AND ASSURANCE
The Sponsor employees and/or their contracted representatives utilize Standard Operating 
Procedures (SOPs) designed to ensure that research procedures and documentation are 
consistently conducted/prepared to the highest quality standards.  These SOPs also require 
compliance with Health Authority regulations and Good Clinical Practice guidance. 
A Quality Assurance audit may be conducted by the Sponsor or its designee at any time 
during or after completion of a study.  The Investigator will be given adequate notice if 
he/she is selected for an audit.  The audit will include, but is not limited to, a review of all 
informed consent forms, a review of study worksheets, associated source documents and 
medical records, a review of regulatory documentation, an assessment of study conduct and 
protocol compliance, and a review of the investigational drug accountability.  At the 
conclusion of an audit, the auditor will conduct a brief meeting with the Investigator to 
review the findings of the audit.

INSTITUTIONAL REVIEW BOARD
Prior to the initiation of the study, the protocol, the informed consent form and 
investigator’s brochure will be submitted to the IRB for approval.  By signing the 
"Statement of Investigator" form (form FDA 1572), the investigator is assuring that an IRB 
which complies with the requirements set forth in 21 CFR Part 56 will be responsible for 
the initial and continuing review of the proposed clinical study.  A copy of the IRB 
approval letter for the protocol, the informed consent, and the protocol signature page must 
be submitted to the Sponsor or its designee, prior to release of investigational supplies to 
the study site.  The approval letter must refer to the specific protocol and the informed 
consent form.  The study site must maintain an accurate and complete record of all reports, 
documents and other submissions made to the IRB concerning this protocol.  A list of the 
IRB members, their titles or occupations, and their institutional affiliation, or an IRB 
assurance number must be provided to the Sponsor or its designee prior to release of study 
supplies. 
FDA/relevant health authority regulations require that all advertisements for subject 
recruitment be approved by an IRB prior to implementation.  The complete text and format 
must be submitted to the Sponsor or its designee for approval prior to IRB submission. 
The investigator is responsible for notifying the IRB of any serious adverse events as 
required by the IRB.  
Status reports must be submitted to the IRB at least once a year (or more frequently as 
required by the IRB) and the IRB must be notified of completion or termination of the 
study.  A final report must be provided to the IRB and the Sponsor within 1 month of study 
completion or termination.  This report should include: any deviations from the protocol, 
the number of participants evaluated, the number of participants who withdrew or were 
withdrawn and the reasons for withdrawal, any significant adverse events and the 
investigator’s summation of the study. 
9.
INFORMED CONSENT PROCESS
It is the responsibility of the investigator or designee to inform each subject, prior to the 
screening evaluation, of the purpose of this clinical trial, including possible risks and 
benefits and document the informed consent process in the subject’s chart.  A sample 
informed consent form containing the required elements of informed consent is provided in 
Appendix 1.  Any changes made to this sample must be approved by the Sponsor or its 
designee, prior to submission to an IRB.  After approval by the Sponsor or its designee, the 
informed consent must be submitted to and approved by an IRB.  Prior to entry into the 
study or initiation of any study-related procedures, the subject must read, sign and date the 
informed consent form.  The person executing the consent must also sign and date the final 
consent form page.  One original informed consent form is to be retained by the study site 
and a copy is to be given to the subject.  The informed consent process must be 
documented in the subject’s medical record. 

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 25 of 45 
The informed consent must be written in a language in which the subject is fluent.  If a 
foreign language translation is required, a statement of certification of the translation must 
be issued.  Regulations require that foreign language informed consent forms be submitted 
to the IRB for approval.  The investigator must forward a copy of the consent form, the 
certified foreign language translation and an IRB approval letter to the Sponsor or its 
designee. 
10.
CONFIDENTIALITY
In accordance with GCP and with the national data protection laws, all information 
concerning the subjects in the study must be treated as strictly confidential by all persons 
involved in the study. 
The investigator acknowledges that any and all information acquired from the Sponsor or 
its designee or developed or acquired in connection with the study are strictly confidential.  
The investigator will not disclose any confidential information to any third party nor use 
confidential information for any purpose without first obtaining the consent of Sponsor in 
writing.  Such consent shall be deemed to have been given for disclosure to any person for 
whom the investigator is responsible at his/her center, but only so far as required for the 
purposes of the study, and, in the case of disclosures to staff, only if such staff are bound by 
obligations of confidentiality no less strict than those set out herein. 
11.
PROTOCOL AMENDMENTS
The Sponsor will document modifications to the protocol in the form of a written 
amendment.  Protocol modifications that impact subject safety or the validity of the study 
must be approved by the IRB before implementation.  In the case of a medical emergency, 
to remove immediate apparent hazard to subjects, a change may be made preferably after 
discussion with the Sponsor or its designee.  In these instances, the IRB and FDA will be 
notified as soon as possible.  
12.
DATA MANAGEMENT
Electronic data capture (EDC) will be utilized for this study.  Study worksheets will be 
provided by the Sponsor or its designee to the site before data collection.  In order to 
facilitate data entry, the worksheets coincide with the data entry pages in the EDC system.  
The design of the data entry screens will follow the same flow as the provided worksheets 
in order to insure minimal issues during data entry.  If the site elects to use the worksheets, 
appropriate worksheets will be completed and initialed or signed where indicated at each 
examination.  All worksheets will be completed in a legible manner in black/blue ink.  
Alternatively, the site may elect to use their own source documents.  It is expected there 
will be source data for all entries in the EDC. 
Any corrections to the worksheets will be made by drawing a single line through the 
incorrect entry, recording the correct information, and initialing and dating the change.  

Protocol VMDN-003b/C 
CONFIDENTIAL 
Helixmith Co., Ltd. 
Page 26 of 45 
The study worksheets and data entered in the EDC system will be audited by the Study 
Monitor. 
Once the data is ready to be entered into the EDC System, then the site will begin entering 
the data into the system.  Afterwards, the monitor will review the data against the source 
documents and/or worksheets and either approve the data records or create queries to the 
site for further review.  If the data records are deemed “clean” with the approval of the 
monitor, then the investigator can e-sign the records.  Finally, when the data records are 
ready to be locked, the data manager will perform the interim lock in the system.  However, 
the data manager also has the right to unlock the data record if any updates to the data are 
necessary.  
Data are protected by preventing unauthorized users from accessing the system with the 
use of username and password combination.  In addition, each individual user will be 
assigned a specific role in the EDC System which will grant that user the right to view, edit 
and/or delete the data.  Furthermore, any changes to the data are captured in the EDC 
System’s audit trail where a reason for change is required.   
All clinical data generated in the study will be submitted to the Sponsor or designated CRO 
for quality assurance review and statistical analysis.  All worksheets and data entered into 
the EDC system will be reviewed for completeness and evident recording errors will be 
rectified by contact with the appropriate clinical site.  Computerized data checks will be 
used to identify unusual data entries for verification prior to statistical analysis. 
To minimize the amount of missing data, investigators will be trained on the deleterious 
effect that missing data have on trial integrity and credibility and that missing data could 
diminish the scientific value of all subjects' altruistic contributions.  
13.
RECORD KEEPING AND RETENTION
Data generated for the study should be stored in a limited-access file area and be accessible 
only to representatives of the study site, the Sponsor and its representatives and 
FDA/relevant health authorities/regulatory agencies.  All reports and communications 
relating to study subjects will identify subjects only by initials and subject identification 
number.  Complete subject identification will be kept by the investigator.  This information 
will be treated with strict adherence to professional standards of confidentiality. 
An investigator must in reasonable time, upon request from any properly authorized officer 
or employee of FDA/relevant health authority or regulatory agency, permit such officer or 
employee to have access to requested records and reports, and copy and verify any records 
or reports made by the investigator.  Upon notification of a visit by the FDA/relevant health 
authority or regulatory agency, the investigator will contact the Sponsor or its designee 
immediately.  The investigator will also grant Sponsor representatives the same privileges 
offered to FDA/relevant health authority or regulatory agents/officers/employees.

Controlled, Multicenter Study to Assess the Safety and Efficacy of VM202 in Subjects with 
Painful Diabetic Peripheral Neuropathy”, also known as the VMDN-003 study. 
The current study is intended to help determine the long-term safety and efficacy of VM202 in 
subjects with painful diabetic neuropathy.  No additional administration of study drug will be 
performed, but you will be asked to complete one additional pain diary and return to the research 
clinic for one more visit to evaluate your pain and your current medical status. 
Who is in charge of this study? 
The Principal Investigator is [INSERT PRINCIPAL INVESTIGATOR NAME].  This study is 
sponsored and funded by Helixmith Co., Ltd Co., Ltd.  [insert PRINCIPAL INVESTIGATOR 
NAME] is being paid by Helixmith Co., Ltd Co., Ltd. to conduct this study.  Together with your

contract research organization, in addition to specialized laboratories to manage some parts of 
the detailed requirements of the study.   
How many people will take part in this research study? 
About 157 patients who are still enrolled in the VMDN-003 study or recently finished the 
VMDN-003 study throughout the 24 research centers in the United States will be invited to 
participate.   
What happens if I agree to be in this research study? 
After you sign this consent form indicating you want to participate in this study, you will be 
asked to fill out a daily questionnaire for a week (7 days).  You will be asked to assess your 
average pain in your feet and lower legs on a scale of 0 - 10 (with 0 = no pain, and 10 = worst 
possible pain) every day.  You will also be asked to describe if your pain in your feet and lower 
legs interfered with your sleep on a scale of 0 - 10 (with 0 = pain did not interfere with sleep, and 
10 = pain completely interfered; I was not able to sleep due to pain).   
You will complete the daily questionnaire within 14 days of a return visit to the research clinic.  
The visit will be scheduled to occur approximately 1 year from the date that you received your 
first injections of study drug for the VMDN-003 study (365 days).
