Methodology:  
This is a Phase II multicentre, double-blind, randomised, placebo-controlled, dose finding study to 
define the optimal doses of Dysport and evaluate its efficacy and safety compared to placebo in 
vulvodynia subjects with PVD. The study will consist of a dose escalation stage (Stage 1) and a 
dose expansion stage (Stage 2). Both Stage 1 and Stage 2 will consist of a double-blind period (with 
treatment cycle 1; Dysport or placebo) followed by an open-label treatment period (treatment cycles 
2 to 4 in which all subjects receive Dysport). Two optimally safe and effective doses of Dysport 
selected from Stage 1 (ranging from 100 U up to a maximum of 800 U) will be further investigated 
in the Stage 2. 
Stage 1 (Dose Escalation) Double-Blind Period: 
It is intended to enrol up to seven dose level cohorts of secondary PVD subjects (i.e. having a past 
history of pain-free intercourse or insertion of any object >1 cm diameter; hereafter referred to as 
PVD2 subjects). Each cohort will include 10 unique evaluable PVD2 subjects. Subjects in these 
cohorts will be randomised in a ratio of 4:1 (Dysport: 8 + Placebo: 2) in a dose-escalation manner 
starting with a total Dysport dose of 100 U, then 300 U, and thereafter increasing up to a maximum 
of 800 U by increments of 100 U.  
For Dysport doses equal to or above 400 U, cohorts of primary PVD subjects (i.e. having life-long 
provoked vestibular pain; hereafter referred to as PVD1 subjects), will be recruited in parallel with 
PVD2 cohorts and at the same Dysport dose as for the PVD2 cohorts. The first PVD1 cohort at 400 
U will include eight unique evaluable subjects who will be randomised in a ratio of 3:1 
(Dysport: 6 + Placebo: 2). Further PVD1 cohorts (i.e. above 400 U) will include 10 unique 
evaluable subjects randomised in a ratio of 4:1 (Dysport: 8 + Placebo 2). 
The recommendation for dose escalation/de-escalation and the staggering scheme for the subsequent 
cohort will be agreed at data review committee (DRC) meetings upon review of efficacy and safety 
data from the previous cohort(s). 
Subjects who discontinue prior to Week 6 for reasons unrelated to occurrence of dose limiting 
events (DLEs) may be replaced at the discretion of the investigator and sponsor. When all subjects 
in Stage 1 have completed 6 weeks of follow-up of treatment cycle 1, the DRC will meet again to 
enable selection of dose(s) to be assessed. PVD1 subjects will be recruited in Stage 2 based on the 
DRC review of efficacy and safety data obtained from PVD1 cohort(s) in Stage 1. 
Following evaluation of study eligibility at the Screening Visit (Day -14), subjects will receive 
study treatment injections in the pelvic floor muscles on Day 1 (Baseline Visit). Follow-up visits 
will be performed at:  
• 
Week 2 (telephone contact) 
• 
Week 6  
• 
Week 12 and  
• 
Every 6 weeks up until eligible for retreatment or up to a maximum of 48 weeks of 
follow-up.  
An intermediate analysis will be performed to review the unblinded data from all cohorts in Stage 1 
up to Cycle 1-Week 12 in an effort to select the two doses for Stage 2 taking into account the dosing 
recommendations from the DRC. 
Stage 2 (Dose Expansion):  
As for Stage 1, the maximum permitted dose in Stage 2 will be 800 U. Two dose levels identified 
from Stage 1, recommended by the DRC based on efficacy and safety data, will be investigated 
further and compared to placebo. It is intended to enrol 63 subjects in Stage 2 in the randomisation

ratio of 1:1:1 (Dysport high dose: 21; Dysport low dose: 21 and Placebo: 21). Following the review 
of data available from Stage 1, the sample size may be formally recalculated for Stage 2 after the 
intermediate analysis. 
Following evaluation of study eligibility during a 14-day screening period, subjects will receive 
study treatment injections in the pelvic floor muscles on Day 1 (Baseline Visit). Treatment 
paradigm and follow-up visits will be the same as in Stage 1. 
Open-Label Period (Stage 1 and Stage 2): 
From Week 12 onwards of the double-blind period, subjects will be assessed for the need for 
retreatment at each visit. Subjects who require retreatment will be provided subsequent treatment 
with Dysport in the open-label period of the study and can receive up to three treatment cycles with 
Dysport administered at least 12 weeks apart. Dysport dose levels, that are approved by the DRC 
will be used for retreatment and will not exceed 800 U. Retreatment with Dysport will be provided 
to subjects when this is in the best interest of the subject based on investigator’s judgement, the 
subject has not experienced any unacceptable adverse event (AE) as judged by the investigator and 
at least 12 weeks have elapsed since the last treatment received.  
Study Duration (Stage 1 and Stage 2): 
Individual subject participation in this study will be for a maximum of 54 weeks:  
• 
Screening: 2 weeks (plus 2 weeks window) 
• 
Follow-up: a maximum of 48 weeks follow-up plus 2 weeks window period for the EOS 
Visit depending on the number of treatments administered and the treatment intervals.  
The subject’s participation in the study will be considered to have ended 36 to 48 weeks after the 
first dose, but not before 12 weeks have elapsed after the last dose.  
The number of treatment cycles will depend on the duration of each treatment cycle. A subject can 
receive a maximum of four treatment cycles of Dysport including the one received in the 
double-blind period. The minimum follow-up duration will be 36 weeks and the maximum follow-
up duration will be 48 weeks plus a 2-week window period for the EOS Visit, (the end of the study 
will not occur before 12 weeks have elapsed from the last treatment cycle), as calculated from 
Cycle 1-Day 1. 
Number of Subjects Planned:  
The study will include approximately 180 female subjects (up to 118 in Stage 1 if all cohorts are 
reached, and 63 in Stage 2).

Test Product, Dose and Mode of Administration: 
Study treatment kits will be designed to maintain the blind (for the subject, investigator and 
delegated person reconstituting the product) during the double-blind period. 
The investigational medicinal product (IMP), Dysport, will be provided as a white, lyophilised 
powder in glass vials containing 300 U or 500 U of BTX-A-HAC. 
Before each administration, the powder will be reconstituted at the study site with 0.9% sterile 
(preservative free) sodium chloride for injection. 
A total volume of 2.5 mL of the reconstituted treatment will be injected intramuscularly at five 
needle insertion points at 10 injection sites (5 mm (superficial) and 10 mm (deep) depths at each 
needle insertion point) across the four pelvic floor muscles: pubococcygeus, bulbospongiosus, 
superficial transverse perineal muscle and deep transverse perineal muscle. 
Injection procedures are described in the ‘Study Treatment Administration - Training Manual’ 
(included in the Study Manual). Training on injection procedures will be provided to each 
investigator performing IMP administration.  
Duration of Treatment: 
Each subject will receive one IMP administration during the double-blind period followed by one to 
three treatments with Dysport in the open-label period (if clinically indicated) at least 12 weeks 
apart. The maximum total follow-up duration will be for up to 48 weeks, plus a 2-week window 
period for the EOS Visit, from the first IMP dose administered and not before 12 weeks have 
elapsed since the last treatment dose. 
Reference Therapy, Dose and Mode of Administration:  
Study treatment kits will be designed to maintain the blind (for the subject, investigator and 
delegated person reconstituting the product) during the double-blind period.  
The comparator will be a matching placebo, i.e. undistinguishable from the active IMP (Dysport), 
which will be injected during the double-blind period (i.e. treatment cycle 1 of Stage 1 and Stage 2) 
of the study. 
Placebo will be provided as a white, lyophilised powder in glass vials, and will be similar in size, 
colour and appearance to the active IMP (Dysport). It will be composed of only the excipients 
contained within Dysport, without the addition of the active substance.

in all subjects in Stage 1 up to 400 U and in a subset of subjects in Stage 2. 
(Note: in Stage 2, this endpoint will be evaluated in subjects who have never had a vaginal 
delivery (including an attempted vaginal delivery), and at study sites that were provided a 
perineometer to assess pelvic floor muscle pressure) 
• 
Resting vaginal pressure 
• 
Maximal ‘squeeze’ pressure. 
• 
Mean change from Baseline in the depression score using PHQ-9 scale. 
• 
Mean change from Baseline in quality of life (QoL) using 36-item Short Form Survey 
(SF-36). 
Statistical Methods: 
Method of Randomisation:  
Stage 1: For the PVD2 cohorts, subjects will be randomised with a 4:1 (Dysport: placebo) ratio. For 
the PVD1 cohort(s), subjects will be randomised with a 3:1 (Dysport: placebo) ratio for Dysport 
400 U and then randomised at 4:1 for Dysport 500 U and up to a maximum of 800 U.  
Stage 2: Subjects will be randomised to Dysport high dose, Dysport low dose, or placebo with a 
1:1:1 allocation. Randomisation will be stratified by pain onset subtype (two levels: primary, i.e. 
having life-long PVD, secondary, i.e. having acquired PVD after period of pain-free penetrative 
activities).  
Sample Size and Power Considerations:  
Stage 1: With 8 evaluable subjects on active treatment per PVD2 dose cohort and if there are 
0 DLEs in a cohort, there is at least 80% probability that the true incidence of DLEs at the 
corresponding dose will not be greater than 18%. With 16 evaluable subjects on active treatment in 
PVD2 and PVD1 dose cohorts, and if there are 0 DLEs in the two cohorts, there is at least 80% 
probability that the true DLEs at the corresponding dose will not be greater than 9%. The ability to 
confidently rule out smaller true DLE incidence at a dose level will come from observations on 
subjects in Stage 2.  
Stage 2: The study sample size required to have at least 80% power to detect a 2-point improvement 
between Dysport and the placebo group on mean change from baseline to Week 6 in the vaginal 
dilator induced pain as reported on a numeric pain rating scale (using the DMTS), assuming a 
common standard deviation of 3-point and using a one-sided 0.10 level test is 21 subjects per arm.

At the end of Stage 2, if the true DLE rate is 6% or greater, there is at least 80% probability to 
observe at least 1 DLE in 29 subjects (8 in Stage 1 and 21 in Stage 2). Therefore, if there are no 
observed DLEs in both Stage 1 and Stage 2 at a dose level, then there is good confidence that the 
true DLE rate is no more than 6%. If the dose chosen in Stage 2 has been tested on two cohorts 
(PVD1 and PVD2) in Stage 1, at the end of Stage 2, if the true DLE rate is 5% or greater, there is at 
least 80% probability to observe at least one DLE in 37 subjects (16 in Stage 1 and 21 in Stage 2). 
Therefore, if there are no observed DLEs in both Stage 1 and Stage 2 at a dose level, then there is 
good confidence that the true DLE rate is no more than 5%. 
Following the review of data available from Stage 1, the sample size may be formally recalculated 
for Stage 2 after the intermediate analysis. 
Statistical Procedure for the Efficacy Testing:  
Change from baseline to Week 6 in pain measurement at the DTMS will be analysed using analysis 
of covariance adjusting for baseline pain at the DTMS and pain onset subtype (primary and 
secondary PVD).  
Hypothesis tests will be one-sided. The planned statistical comparisons at one-sided 0.10 level do 
not adjust for two treatment comparisons and consequently the experiment-wise type I error rate 
may be up to 20%. Non-parametric tests may also be carried out to evaluate robustness of results. 
Subject who discontinue prior to Week 6 for reasons unrelated to safety may be replaced at the 
discretion of the investigator and sponsor. Sensitivity analyses will be carried out to evaluate the 
impact of missing data where appropriate. 
Data Review Committee (DRC) Meetings:  
A DRC will be established to make recommendations for dose escalation and dose de-escalation 
(within the Dysport dose range of 100 U up to a maximum of 800 U) or study termination in 
Stage 1. If no subject reports a clinically significant AE in a cohort, the DRC will meet once all 
evaluable subjects have reached Week 6 of a cohort to review the efficacy and safety data and 
recommend the dose for the next cohort or proceed to Stage 2.  
If any subject reports a clinically significant AE, then further enrolment into the cohort, as well as 
retreatment in open label cycles at the current dose, will be suspended and an ad hoc DRC meeting 
will be scheduled to review the safety data and make a recommendation with regards to further 
conduct of the cohort and of Stage 1. At the end of Cycle 1-Week 6 for all subjects in Stage 1, the 
DRC will meet to review efficacy and safety data and recommend the two doses of Dysport to be 
assessed in the Stage 2 of the study. The DRC will also recommend if further PVD1 cohort(s) are 
required or if PVD1 subjects should be removed from Stage 2. 
In Stage 2 of the study, ad hoc DRC meetings will be scheduled to review efficacy and safety data 
in the event of an emergency safety issue. 
Primary Analysis: 
A primary unblinded analysis will be conducted once all Stage 2 subjects have reached the 
Cycle 1-Week 12 visit; this will include all available safety and efficacy data from subjects in 
Stage 1 and Stage 2 subjects until the cut-off date.  
A final analysis will be carried out once all subjects have completed end of study evaluation. 
Intermediate Analysis: 
At the point when the DRC recommends moving to Stage 2 of the study, an intermediate unblinded 
analysis will be performed. Available data from all double-blind periods of all cohorts from Stage 1 
until the last subject has completed their Cycle 1-Week 12 visit will be considered in the analysis. 
Descriptive statistics of the TEAEs and selected efficacy endpoints will be carried out. 
Following the review of data available from Stage 1, the sample size may be formally recalculated 
for Stage 2 after the intermediate analysis.

BACKGROUND INFORMATION 
1.1 
Introduction 
Vulvodynia is defined as vulvar pain of at least 3 months' duration, without a clear 
identifiable cause, and which may have potential associated factors. The vulvar pain can be 
either localised, generalised or mixed; it could be either provoked (insertional or contact) or 
spontaneous or both; the onset vulvodynia can be primary or secondary [1]. The chronic 
vulvar pain is often associated with sexual dysfunction and affective distress [2]. Vulvodynia 
is a fairly prevalent condition with lifetime estimates ranging from 8% to 28% based on the 
prevalence studies in women of reproductive age group in the general population [3, 4, 5]. 
Vulvodynia affects young women [6], with the average age of occurrence being 
approximately 40 years, although a high prevalence is observed in all decades of life until age 
of 70 years [2, 3].  
Provoked vestibulodynia (PVD), previously known as vulvar vestibulitis, is the most common 
form of vulvodynia and occurs when pain is localised in the vulvar vestibule and triggered by 
any vestibular contact (sexual or otherwise). In a population-based study, 64.8% of 
vulvodynia patients had provoked pain only [3].  
There is currently no approved drug for the treatment of vulvodynia. A typical treatment plan 
for a woman with vulvodynia starts with treatments that are considered non-pharmacological 
(e.g. psychological treatments, physiotherapy) and, depending on her response to treatment, 
can progress to multiple different medication treatments, that are used as off label treatment 
for the condition without any established proof of benefit (e.g. tricyclic antidepressants, local 
anaesthetic agents, topical hormones, anti-inflammatory agents, pain modulators, local nerve 
block and anticonvulsant medications). If these treatments fail, then surgical intervention 
(e.g. vestibulectomy for localised provoked vestibulodynia) is recommended [7], however 
only a minority of patients may be suitable for vestibulectomy [8]. Although surgical 
treatment may be successful, it is associated with postoperative complications such as 
decreased vaginal lubrication and worsening of pain, hence is best reserved for refractory 
cases [2].  
There are relevant and convincing medical observations and arguments to suggest that 
neuromuscular disorder of the pelvic floor muscles may be responsible for PVD characterised 
by localised provoked pain at the vaginal vestibule. Several studies provide significant 
evidence that patients with PVD have greater muscular hypertonia in the muscles in the 
superficial area of the perineum, which become painful and that the hypertonic pelvic 
musculature plays a role in the etiology, maintenance, and exacerbation of PVD [9]. Eighty 
percent of patients of PVD have muscular hypertonia of the pelvic floor muscles 
demonstrable by electromyography, and 90% of these patients tend to have associated vulvar 
allodynia [10]. Bohm-Starke found that an intraepithelial hyperplasia of the C-nerve fibres 
was present in the vestibular tissue, along with the presence of various pain neurotransmitters 
such as glutamate or substance P [6, 11]. All these factors support the neuromuscular 
hypothesis of the disease with an abnormal pain transmission [10]. Other treatment 
approaches for the condition, like physiotherapy are also aimed at the rehabilitation of the 
pelvic floor musculature to normalize the muscle tone, to increase elasticity of tissues at the 
vaginal opening, to desensitize the vulvo-vestibular area and decrease the patient’s protective 
guarding reactions to vaginal penetration by exercises, manual techniques, biofeedback, and 
electrical stimulation [9].

Botulinum toxin (BTX) is a neurotoxin that acts on the presynaptic motor neuron, cleaves the 
SNARE proteins thereby inhibiting the release of acetylcholine and thus leading to a 
reduction in muscle tone [12]. Aligned with the known pharmacological and 
pharmacodynamic action of Dysport® on the injected muscles, there is strong evidence to 
suggest its effectiveness in the treatment of vulvodynia by causing muscle relaxation of the 
affected pelvic floor muscles, and by inhibiting the release of neuropeptides and 
neurotransmitters involved in chronic pain and inflammation (Substance P and calcitonin gene 
related peptide) [6, 10, 13]. As a consequence, local treatment with Dysport in patients with 
vulvodynia is expected to provide relief from vulvar pain, subsequently improving the sexual 
function of women and their quality of life.  
Considering the unmet need for an effective treatment for vulvodynia patients and the 
suggested efficacy of botulinum toxin-A (BTX-A) in the various published studies for this 
indication, Ipsen proposes to conduct a randomised, double-blind, placebo-controlled study 
designed to define optimal doses of Dysport and evaluate its efficacy and safety compared 
with placebo for the treatment of vulvodynia. 
1.2 
Name and Description of Investigational Medicinal Product(s) 
Botulinum toxin-A is a potent neurotoxin isolated from the bacterium Clostridium botulinum, 
a gram-positive, spore-forming anaerobe. Botulinum toxin-A, a single chain protein with a 
molecular weight of approximately 150000 Daltons (Da), is one of seven different serotypes 
(classed A through G) of BTX produced by this organism. Proteins endogenous to the 
bacterium cleave the single chain protein, resulting in a di-chain neurotoxin containing a light 
chain (molecular weight of approximately 50000 Da) and a heavy chain (molecular weight ca. 
100000 Da) that remain linked by inter-chain disulfide and noncovalent bonds. 
Dysport is a freeze-dried preparation of Clostridium BTX-A-haemagglutinin complex 
(BTX-A-HAC) formulated with lactose (bulking agent) and human serum albumin. 
A more detailed description of the product is given in Section 6.2.1.1. 
Further details can also be found in the Dysport IB. 
1.3 
Findings from Nonclinical and Clinical Studies 
1.3.1 
Summary of Nonclinical Studies 
An extensive nonclinical development program for Dysport exists, including pharmacology, 
distribution, and toxicology studies (including repeat use). In this program, animals (both 
males and females) have been treated by intramuscular administration of Dysport in striated 
muscles (gluteus and gastrocnemius muscles). Dysport was also studied nonclinically in the 
detrusor muscle.  
In vivo pharmacodynamic (PD) studies conducted in rats (rat muscle force test and muscle 
glycogen depletion) showed significant decreased mass and force of intramuscular injection in 
the gastrocnemius muscle and inhibition of glycogen depletion in injected rat muscles.  
Distribution studies performed with BTX-A have demonstrated that the majority of the toxin 
remained localised at the injection site, supporting the local effect of the toxin.  
The results of the single or repeat dose (up to 6 months) toxicity studies demonstrated that 
BTX-A administered in striated muscle has been locally well tolerated by the animal species 
used and that it possesses no potential for producing nonpharmacologically related toxicity or 
specific target organ effects. The effects on injected muscles (decrease in muscle and 
myofibre size) were related to the pharmacological activity of BTX-A and were consistent 
with the results of the PD rat muscle force test. They were reversible and appeared to cause no

long term impairment of neuromuscular junction. When administered by the intradetrusor 
route, no histopathological modification of the bladder or adjacent reproductive organs was 
detected. The effects seen in the single dose intradetrusor studies in rats were consistent with 
the ones observed in previous striated muscle studies after single and repeated administrations 
on rats. Dysport was locally well tolerated by both routes of administration. 
The drug was not teratogenic in rats and rabbits and no effects were observed in the pre and 
postnatal study on the F1 generation in rats (male and females). The drug did not alter male or 
female rat fertility except at doses inducing localised muscle paralysis and alteration of 
general conditions (severe decreased body weight and food consumption). Given in 21-day 
old rats (corresponding to children of 2 years old), Dysport did not affect postnatal growth, 
reproductive, neurological and neurobehavioral development.  
The existing nonclinical development program for Dysport conducted in striated and in 
detrusor muscles provides a robust and adequate safety and efficacy data set to support the use 
of Dysport as a treatment option in female patients with vulvodynia when injected in the 
pelvic floor striated muscles. 
Further details can also be found in the Dysport IB. 
1.3.2 
Summary of Clinical Studies 
No previous clinical studies have been conducted by Ipsen with Dysport in this indication of 
vulvodynia. This is the first study that will be conducted by Ipsen in this indication. The body 
of clinical evidence mostly consists of data from several small scale published studies in the 
treatment of vulvodynia and other related conditions (e.g. vaginismus) conducted either with 
Dysport [14, 15] or with other BTX-A formulations [6, 10, 12, 13, 16, 17, 18, 19, 20]. 
1.4 
Known and Potential Risks and Benefits to Human Subjects 
Dysport was first approved for the treatment of blepharospasm and hemifacial spasm in the 
United Kingdom in 1990. Since then Dysport® has been approved in over 85 countries for a 
range of indications. The posology and safety of Dysport has been established in numerous 
clinical studies and there is over 25 years of postmarketing experience. 
Dysport is generally well-tolerated, although temporary paralysis of nontargeted muscle 
groups may occur. Adverse events (AEs) resulting from a possible remote spread of the toxin 
from its site of injection have been reported (including excessive muscle weakness and 
aspiration pneumonia resulting from dysphagia). Local spread of the toxin from the injection 
site has also been reported and therefore the safety profile is dependent on the site of 
injection. Most AEs are of mild or moderate severity and of limited duration. The profile of 
adverse reactions reported during postmarketing use reflects the pharmacology of the product 
and AEs seen during clinical studies. There have been occasional reports of hypersensitivity.  
Adverse reactions that are considered expected in patients treated across a variety of 
indications can be found in the current Dysport IB and in the Dysport Company Core Safety 
Information. 
Based on published data in the treatment of vulvodynia and other related conditions 
(e.g. vaginismus) with Dysport or other BTX-A formulations and the mechanism of action of 
Dysport, urinary incontinence and faecal incontinence may also be observed in patients 
injected in pelvic floor muscles.  
Treatment with Dysport in female patients with vulvodynia is expected to provide an 
improvement in the provoked pain (at intercourse or from any kind of vestibular pressure) and

therefore potentially an improvement in the associated sexual function, depression and quality 
of life. 
Based on clinical evidence available from published data supporting the efficacy of BTX-A in 
adult female patients with vulvodynia, the known mechanism of action of Dysport and the 
proposed range of Dysport doses to be tested (100 U up to a maximum of 800 U) that fall 
within the range of approved doses for Dysport (up to 1500 U in adult patients), the 
benefit/risk balance is expected to be favourable for evaluation in this patient population.  
Additional information regarding potential risks and benefits may be found in the current 
Dysport IB. 
1.5 
Selection of Investigational Medicinal Products and Dosages 
The selection of Dysport doses to be evaluated in the dose escalation stage of the study are 
based on the clinical evidence from published studies with Dysport and other BTXs in the 
literature as well as the sponsor’s clinical experience with Dysport in various indications 
involving targeted treatment of hypertonic muscles at several anatomical sites.  
In a study by Bertolasi 2009 [15] injection of the levator ani muscle with low mean doses of 
Dysport (24 U±12 U) led to some reduction in vulvar pain in patients with PVD with 
vaginismus and no major AEs were reported with Dysport administration. Amongst the 
approved indications in the US, for the treatment of glabellar lines, Dysport 50 U achieves a 
clinical effect (i.e. causes muscle relaxation) when administered at 5 injection sites in three 
muscles in the glabellar area (two corrugators and one procerus) that have a relatively small 
muscle mass and no events suggestive of remote distribution of toxin have been reported in 
this indication at this dose. In this study, Dysport is to be injected at 5 sites across 6 muscles 
of the pelvic floor: bulbospongiosus (left and right), pubococcygeus (left and right), deep 
transverse muscle and superficial transverse muscle. Based on sponsor experience, a total 
Dysport dose of 100 U distributed between 6 muscles of the pelvic floor should be a safe 
starting dose, which may show some degree of muscle relaxation. 
Ipsen proposes to progressively escalate Dysport doses from 100 U and 300 U, and then 
increasing up to a maximum dose of 800 U by increments of 100 U. Dysport doses up to 
400 U are supported by data from the study by Ghazizadeh 2004 [14], in which the starting 
dose of 150 U Dysport injected into the levator ani (puborectalis) muscles in patients with 
vaginismus did not provide sufficient clinical improvement in some patients, following which 
the dose was gradually increased to 400 U for subsequent patients that lead to satisfactory 
relief from vaginismus in 95.8% of patients. No adverse effects were reported in this study 
with Dysport doses of 150 U to 400 U. Administration of Dysport doses above 400 U and up 
to a maximum of 800 U during the study will be based on recommendation by the DRC 
following review of safety and efficacy data from previous cohorts. 
A more detailed description of administration procedures is given in Section 6.2.2.  
1.6 
Compliance Statement

1.7 
Population to be Studied 
The study will recruit premenopausal adult female subjects aged 18 years or above. 
In order to establish the preliminary efficacy of Dysport in this dose finding study, a subset of 
vulvodynia subjects suffering from provoked vestibular pain is selected. It is hypothesised 
that pelvic floor muscle hypertonicity underpins the posterior vestibular pain experienced and 
consequently these subjects are likely to respond to treatment with Dysport. This will ensure 
enrolment of a homogenous target population and limit intersubject variability. 
Subjects suffering from PVD for at least 6 months duration but no more than 15 years, having 
pain at the posterior vestibule will be enrolled into the study. The subjects should have taken a 
stable physiotherapy (if any) for at least 12 weeks prior to the entry into the study and not 
have received any BTX for any indication within the last 1 year.

PURPOSE OF THE STUDY AND STUDY OBJECTIVES 
2.1 
Purpose of the Study 
Dysport, a BTX-A-HAC, is already approved in the US and in many other countries 
worldwide for the treatment of a variety of clinical conditions in adult patients like cervical 
dystonia, upper and lower limb spasticity, that are associated with muscular hypertonicity, and 
pain in several patients. 
The therapeutic value of BTX-A is derived from its ability to specifically and potently 
decrease muscular overactivity, thereby reducing the muscle tone for an extended duration 
and ameliorating the associated pain.  
Based on the known mode of action of Dysport, Ipsen proposes to expand the treatment 
profile of Dysport and potentially add a new indication for the treatment of vulvodynia.   
This study is a double-blind, randomised, parallel group, placebo-controlled study designed to 
define optimal doses of Dysport and evaluate its efficacy and safety compared with placebo 
for the treatment of vulvodynia. Treatment of vulvodynia patients with PVD with Dysport is 
expected to provide not only an improvement in the provoked pain (at intercourse or from any 
kind of vestibular pressure) but also potentially an improvement in the associated sexual 
function, depression and quality of life.

STUDY DESIGN 
3.1 
General Design and Study Schema 
This is a Phase II multicentre, double-blind, randomised, placebo-controlled, dose finding 
study to define the optimal doses of Dysport and evaluate its efficacy and safety compared to 
placebo in vulvodynia patients with PVD. Study treatment will be injected at 5 needle 
insertion points at 10 injection sites in the vestibular area. The study will consist of a dose 
escalation stage (Stage 1) and a dose expansion stage (Stage 2). The purpose of the dose 
escalation will be to determine the Dysport doses to be further investigated in Stage 2. The 
study will include approximately 180 premenopausal female subjects (up to 118 in Stage 1 if 
all cohorts are reached, and 63 in Stage 2) aged 18 years or above with a diagnosis of PVD 
associated with provoked pain at the posterior vestibule. Both Stage 1 and Stage 2 will consist 
of a double-blind period (treatment cycle 1; Dysport or placebo) followed by an open-label 
treatment period (treatment cycles 2 to 4; all subjects receive Dysport). Overall study duration 
and period for individual subject participation are provided in Section 3.8.  
An overview of the study design is presented in Figure 1.  
3.1.1 
Stage 1 (Dose Escalation)  
It is intended to enrol up to seven dose level cohorts of secondary PVD subjects (i.e. having a 
past history of pain-free intercourse or insertion of any object >1 cm diameter; hereafter 
referred to as PVD2 subjects) evaluating Dysport doses ranging from 100 U up to a maximum 
of 800 U (total dose administered) to find two optimally safe and effective doses of Dysport 
that will be further investigated in the Stage 2. Additional dose level cohorts within this dose 
range (100 U and up to a maximum 800 U) may potentially be added based on the 
recommendations from the DRC. 
Each PVD2 cohort will include 10 unique evaluable PVD2 subjects who will be randomised 
via the interactive response system (IRS) to the two double-blind parallel treatment arms in 
4:1 ratio:  
• 
Dysport (N=8) or  
• 
Placebo (N=2).  
Cohort 4 will include 8 unique evaluable primary PVD subjects (i.e. having life-long 
provoked vestibular pain; hereafter referred to as PVD1 subjects), at the same Dysport dose as 
for the PVD2 Cohort 3, who will be randomised via the IRT to the two double-blind parallel 
treatment arms in 3:1 ratio:  
• 
Dysport (N=6) or  
• 
Placebo (N=2).  
Further PVD1 cohorts (i.e. above 400 U) will include 10 unique evaluable subjects 
randomised in a ratio of 4:1 (Dysport N=8 and Placebo N=2). 
In an event, when the last subject in a cohort is being randomised, if an additional subject has 
been screened, this subject may be accepted in the cohort and be randomised. 
At Screening, all subjects will be allocated a subject number. Subjects will be evaluated for 
eligibility during a Screening Visit at Day -14. Following confirmation of eligibility for the 
study, subjects will be allocated to one of the above two treatment groups. Subjects will 
receive study treatment injections in the pelvic floor muscles on Day 1 (Baseline Visit). 
Follow-up visits will be performed at: 
• 
Week 2 (telephone contact)

• 
Week 6  
• 
Week 12 and  
• 
Every 6 weeks up to a maximum of 48 weeks of follow-up.  
The screening and postbaseline assessments to be performed at each visit are discussed in 
Section 5.2. Assessments to be performed at the End of Study (EOS) or Early Withdrawal 
(EWD) visit are presented in Section 5.2.4. 
Once all PVD2 and PVD1 evaluable subjects in a dose level have reached the Week 6 visit, 
the dose escalation for the subsequent cohort will be agreed at the DRC meeting upon review 
of the available efficacy and safety data. The maximum dose to which escalation is permitted 
will be 800 U. The definitions for clinically significant AEs and dose limiting events (DLEs) 
is provided in Section 3.1.1.1. The assessments to be performed by the Data Review 
Committee (DRC) and their timings are discussed in Section 3.1.1.2. Subject who withdraw 
or discontinue prior to Week 6 in the double-blind period for reasons unrelated to occurrence 
of DLEs may be replaced at the discretion of the investigator and sponsor. Replacement 
subjects will receive the same treatment as the subject they replace. Stage 1 will be stopped as 
soon as the dose of 800 U has been tested or otherwise recommended by the DRC. 
At the end of Cycle 1 – Week 6 for all PVD2 subjects in Stage 1, the DRC will meet to 
review efficacy and safety data and recommend the two doses of Dysport to be assessed in the 
Stage 2 of the study. PVD1 subjects will be recruited in Stage 2 following DRC review of the 
efficacy and safety data of PVD1 cohort(s) in Stage 1. 
An intermediate analysis will be performed to review the unblinded data from all cohorts in 
Stage 1 up to Cycle 1-Week 12 in an effort to select the two doses for Stage 2 taking into 
account the dosing recommendations from the DRC. 
From Week 12 onwards of the double-blind period, subjects will be assessed for the need for 
retreatment at each visit. Subjects who require retreatment will be provided subsequent 
treatment with Dysport in the open-label period of the study. Dysport dose levels, that are 
approved by the DRC will be used for retreatment and will not exceed 800 U. Subjects not 
requiring or not eligible for retreatment will be evaluated every 6 weeks ±2 weeks (Additional 
Visit(s)) until they need retreatment or they complete at least 36 weeks of follow-up. The 
number of treatment cycles will depend on the duration of each treatment cycle, and thus the 
minimum follow-up duration will be 36 weeks and the maximum follow-up duration will be 
48 weeks (the end of the study will not occur before 12 weeks have elapsed from the last 
treatment cycle), as calculated from Cycle 1-Day 1. 
The screening and postbaseline assessments to be performed at each visit are discussed in 
Section 5.2. Assessments to be performed at the EOS or EWD visit are presented in 
Section 5.2.4. 
Retreatment criteria are presented in Section 3.7.3. Retreatment dose schedule for Stage 1 is 
presented in Section 3.7.2.1.

Definitions of Clinically Significant Adverse Event and Dose Limiting Event 
A clinically significant AE is defined as:  
• 
Drug-related severe AE or drug related serious AE 
• 
Treatment emergent faecal incontinence, defined as new onset faecal incontinence that 
lasts for more than 4 days and that in the investigator’s opinion is not due to any other 
cause e.g. diarrhoea

• 
Treatment emergent urinary incontinence, defined as: new onset, or a significant and 
sudden deterioration in any pre-existing urinary incontinence in the investigator’s 
opinion, that lasts for more than 4 days and that in the investigator’s opinion is not due 
to any other cause.  
A DLE for the purpose of this study is defined as a clinically significant AE that would 
preclude another drug administration at the same dose level in a given subject. 
3.1.1.2 
DRC Meetings 
A DRC will be established to make recommendations for dose escalation, dose de-escalation, 
progression from Stage 1 to Stage 2 or study termination in Stage 1 of the clinical study (see 
Section 13.3.1 for the composition and operation of the DRC). The maximum dose to which 
escalation will be permitted will be 800 U. 
If no subject reports a clinically significant AE in a cohort, the DRC will meet once all PVD2 
and PVD1 evaluable subjects of a dose level have reached Week 6 to review the unblinded 
efficacy and safety data and recommend the dose for the next cohort. The DRC may 
recommend to reassess the previously used dose level based on the review of efficacy and 
safety data from the cohort(s). 
If any subject reports a clinically significant AE (as defined in Section 3.1.1.1), then further 
enrolment into the cohort, as well as retreatment in open label cycles at current dose, will be 
suspended and an ad hoc DRC meeting will be scheduled.  
During the ad-hoc meeting, the DRC will review blinded data of the subject(s) with clinically 
significant AE and all available efficacy and safety data from the cohort. The DRC may 
request to break the blind to confirm if the significant AE is a DLE, and based on this 
assessment, if enrolment in the cohort may continue. 
At the end of Cycle 1-Week 6 visit for all subjects in Stage 1, the DRC will meet to review all 
safety and efficacy data from the cohort(s) and recommend the two doses to be assessed in 
Stage 2. The DRC will also recommend if further PVD1 cohort(s) are required or if PVD1 
subjects should be removed from Stage 2. 
In Stage 2 of the study, ad hoc DRC meetings will be scheduled to review efficacy and safety 
data in the event of an emergency safety issue. 
3.1.2 
Stage 2 (Dose Expansion)  
Two dose levels identified from Stage 1, recommended by the DRC based on efficacy and 
safety data, will be investigated further and compared to placebo in Stage 2. As for Stage 1, 
800 U will be the maximum permitted dose in Stage 2. It is intended to enrol 63 subjects in 
the randomisation ratio of 1:1:1:  
• 
Dysport high dose (optimal highest safe and efficacious dose): 21 subjects 
• 
Dysport low dose (selected based on safety and efficacy considerations observed in 
Stage 1): 21 subjects, and  
• 
Placebo: 21 subjects.  
Following the review of data available from Stage 1, the sample size may be formally 
recalculated for Stage 2 after the intermediate analysis.  
Subjects will be evaluated for eligibility during a Screening Visit at Day -14. Subjects will 
receive study treatment in the pelvic floor muscles on Day 1. Treatment paradigm and 
follow-up visits will be the same as in Stage 1. From Week 12 visit onwards, the need for 
retreatment will be assessed at each visit.

Retreatment criteria are presented in Section 3.7.3. Retreatment dose for Stage 2 is presented 
in Section 3.7.2.2.  
The number of treatment cycles will depend on the duration of each treatment cycle, and thus 
the minimum follow-up duration will be 36 weeks and the maximum follow-up duration will 
be 48 weeks (the end of the study will not occur before 12 weeks have elapsed from the last 
treatment cycle), as calculated from Cycle 1-Day 1.

appearance allowing the blinded conditions of the first cycle of the study to be maintained 
(Stage 1 and Stage 2).  
During the double-blind period of Stage 1 and Stage 2, subjects and investigators will be 
blinded to treatment assignment (i.e. Dysport/placebo). 
During the double-blind period of Stage 2 subjects and investigators will also be blinded to 
the dose received.

For Stage 1, the sponsor’s randomisation manager who is a statistician, independent from the 
study, will prepare: 
• 
A list of randomisation numbers (List A1). It will be produced in blocks, on an 
unbalanced ratio (4 Dysport: 1 placebo) and will be stratified by cohort. For Cohort 4, 
Dysport randomisation numbers will be deactivated randomly to get an unbalanced 
ratio (3 Dysport: 1 placebo).  
• 
A list of treatment numbers/treatment which will be dispatched to the sites (List B1). It 
will be produced in blocks, on an unbalanced ratio (3 Dysport: 2 placebo). 
For Stage 2, the sponsor’s randomisation manager will prepare: 
• 
A list of randomisation numbers (List A2). It will be produced in blocks, on a balanced 
ratio (1 placebo: 1 Dysport low dose: 1 Dysport high dose) and will be stratified by 
pain onset subtype (primary and secondary PVD). 
• 
A list of treatment numbers/treatment which will be dispatched to the sites (list B2). It 
will be produced in blocks, on a balanced ratio (1 placebo: 1 Dysport low dose: 
1 Dysport high dose). 
Mirror lists of randomisation numbers will also be produced to randomise the replacement 
subjects, so that the subject to be replaced and her replacement are assigned to the same 
treatment arm.  
The randomisation as well as the treatment number(s) assignation at drug dispensation, will 
be managed by an Interactive Response Technology (IRT). After eligibility is confirmed, at 
Baseline (V2), subjects will be assigned to a randomisation number and to the associated 
treatment arm, in sequential order within each study centre and within each level of strata. In 
Stage 1, from Cohort 3 onwards, the IRT will also consider the subject pain-onset subtype for 
cohort/randomisation number assignation. 
Subjects meeting the eligibility criteria will be assigned to a randomisation number, and will 
be allocated to the associated treatment arm, by IRT. A treatment number will be also 
allocated by IRT each time drug is dispensed. The IRT will also manage all the logistical 
aspects of treatments (e.g.: drug supplies, replacement of lost, damaged, quarantined, expiring 
and expired kits). 
This service provides site staff and project team members with a 24-hour per day, 7-day per 
week service (additional details may be found in the IRT reference manual provided to each 
site). In case of medical or technical randomisation or dispensation queries, a 24-hour helpline 
is available –supporting information is provided in the investigator site file.  
Recruitment will stop in each cohort of Stage 1 (and respectively in Stage 2) once 10 (or 8 in 
Cohort 4 only) and respectively 63 evaluable subjects have been randomised with the 
expected ratio.  
Randomised subjects who terminate their study participation for any reason before 
administration of the first dose of randomised study drug will retain their randomisation and 
treatment numbers (i.e. these numbers will not be reused). The next subject will be given 
another randomisation number and another treatment number, even if she should receive the 
same treatment. Non-evaluable subjects will be replaced with a mirror list, so that the 
replacement subject is assigned to the same treatment arm as the replaced subject. 
The sponsor’s randomisation manager will keep the master lists. A copy of lists of treatment 
numbers (lists B1 and B2) will be confidentially supplied to the Ipsen PharmSciences,
 
. Similarly, a copy of lists of randomisation/treatment 
numbers (lists A1, B1, A2 and B2) will be also confidentially supplied to the Contract 
CCI

Research Organisation (CRO) in charge of IRT. Finally, a copy of lists concerning stage 1 
(lists A1 and B1) will be also confidentially supplied to the independent statistician in charge 
of tables, figures and listings (TFLs) for the DRC. The master lists and the copies supplied to 
Ipsen PharmSciences, CRO in charge of IRT and to the independent statistician in charge of 
TFLs for DRC will be kept confidential in a secure location. Access to the randomisation lists 
must be restricted until authorisation is given to release them for final analysis. 
3.6 
Maintenance of Randomisation and Blinding 
In an emergency situation, which requires the identification of the study treatment group, the 
investigator may break the treatment code immediately, or as quickly as possible, if he/she 
finds it is in the best interest of the trial subject. The investigators have direct and immediate 
access to break the treatment code through the IRT. At the earliest opportunity, the 
investigator is requested to inform the blinded monitor in charge of his/her centre that the 
blind has been broken for an emergency. 
In addition, a set of hard copy sealed code break envelopes will be held by Global Patient 
Safety (GPS) at Ipsen, in case of IRT failure (this set will be prepared by Ipsen randomisation 
manager). 
If code-break was performed using the IRT, the investigator must store the email notification 
revealing unblinded treatment in a sealed envelope. The investigator will then sign, date and 
provide reason for the code break on the emergency code break form and on the sealed 
envelope. The date and reason for identifying the treatment group will be recorded in the 
electronic case report form (eCRF). 
Finally, if needed, DRC will be able to unblind any subject of Stage 1, with the hard copy 
sealed code break envelope of her randomisation number (this set of envelopes will be 
prepared by Ipsen randomisation manager) or using the IRT.

3.7.2.1 
Stage 1 
The maximum permitted dose in Stage 1 (double-blind and open-label periods) is 800 U. 
Double-Blind Period (Treatment Cycle 1) 
The starting dose for PVD2 Cohort 1 will be Dysport 100 U or placebo. It is anticipated that if 
there are no safety issues, then the predefined doses for PVD2 Cohorts 2 and 3 will be 300 U 
and 400 U, respectively, and doses for Cohorts 5, 7, 9 and 11 will be 500 U up to a maximum 
of 800 U by increments of 100 U, all with matching placebos. Subjects in PVD1 Cohorts 4, 6, 
8, 10 and 12 will receive the same dose as subjects in PVD2 Cohorts 3, 5, 7, 9 and 11.The 
DRC may recommend to reassess the previously used dose level based on the review of 
efficacy and safety data from the cohorts.  
Open-Label Period (Treatment Cycles 2-4) 
For a given subject, the Dysport dose for treatment cycles 2, 3 and 4 will be based on the 
investigator’s judgement (based on efficacy and safety).  
• 
Treatment cycle 2: the Dysport dose can either be the Dysport dose assessed in the 
previous treatment cycle (double-blind period) for the current cohort or the Dysport 
dose of the following cohort (provided it has been approved by the DRC).  
DB=double-blind, OL=open-label

• 
Treatment cycles 3 and 4: the Dysport dose can either be the dose assessed in the 
previous treatment cycle, a lower dose or the dose of the following cohort (provided it 
has been approved by the DRC).  
If any subject fulfils the retreatment criteria and needs a higher dose for treatment prior to the 
DRC having approved the next dose level, the subject can either accept the dose level 
currently on, or delay injection until the next dose level is approved by the DRC or withdraw 
from the study.  
A subject can receive up to a maximum of 4 treatment cycles with Dysport. The last treatment 
cycle should last at least 12 weeks and should not be initiated after Week 36.  
3.7.2.2 
Stage 2 
As for Stage 1, the maximum permitted dose in Stage 2 (double-blind and open-label periods) 
is 800 U. 
Double-Blind Period (Treatment Cycle 1) 
Depending upon the results from Stage 1 and the recommendation from the DRC, two doses 
of Dysport will be selected.  
• 
Dysport high dose (optimal highest safe and efficacious dose) selected from Stage 1 or 
• 
Dysport low dose selected based on safety and efficacy considerations observed in 
Stage 1 or 
• 
Placebo. 
Open-Label Period (Treatment Cycles 2-4) 
For a given subject, the Dysport dose for treatment cycles 2, 3 and 4 will be:  
• 
Treatment cycle 2: the Dysport dose will be the lowest of the two Dysport doses tested 
in the double-blind period of Stage 2.  
• 
Treatment cycles 3 and 4: as per the investigator’s judgement (based on efficacy and 
safety), the Dysport dose can be either the low or high dose tested during the 
double-blind period of Stage 2. 
A subject can receive up to a maximum of 4 treatment cycles with Dysport. The last treatment 
cycle should last at least 12 weeks and should not be initiated after Week 36.  
3.7.3 
Retreatment Criteria (Stage 1 and Stage 2) 
From Week 12 onwards (Stages 1 and 2), need for retreatment will be assessed at each visit. 
All subjects willing to continue in the study will be offered to receive Dysport (under an 
open-label design). 
Retreatment with Dysport will only be initiated if all of the following criteria are fulfilled 
(retreatment criteria): 
• 
At least 12 weeks have elapsed since the last treatment received.  
• 
Based on investigator’s judgement, this is in the best interest of the subject. 
• 
Subject is willing to be retreated. 
• 
The subject has not experienced any unacceptable AE as judged by the investigator. 
• 
Negative urine pregnancy test. 
• 
Negative drug screen test for illicit drugs.  
Details on dose administration for Stage 1 are provided in Sections 3.7.2.1 and for Stage 2 in 
Section 3.7.2.2.

Study Duration 
This study will consist of a 14-day screening period (Stage 1 and Stage 2), a double-blind 
treatment period including treatment administration at Day 1 and a follow-up period of 36 to 
48 weeks (calculated from the dosing at Day 1). From Week 12 onwards of the double-blind 
period, the subject may enter an open-label treatment period and receive up to three additional 
treatment cycles with Dysport administered at least 12 weeks apart (a maximum of 
4 treatments including the one received in the double-blind period).  
Individual subject participation in this study will be for a maximum of 54 weeks (Stage 1 and 
Stage 2):  
• 
Screening: 2 weeks (plus 2 weeks window) 
• 
Follow-up: a maximum of 48 weeks follow-up plus 2 weeks window period for the 
EOS Visit depending on the number of treatments administered and the treatment 
intervals.  
The subject’s participation in the study will be considered to have ended 36 to 48 weeks after 
the first dose, but not before 12 weeks have elapsed after the last dose.  
The overall duration of the study, including Stage 1 and Stage 2 with a maximum allowed 
dose of 800 U, will be approximately 4 years. The study will be considered to have started 
when the first subject has provided signed informed consent. The study will be considered to 
have ended after the last subject has completed the EOS visit in the study. 
3.9 
Stopping Rules and Discontinuation Criteria 
A specific site or a given cohort can be discontinued or the entire study may be terminated if 
recommended by the DRC at any time during Stage 1 or if the sponsor judges it necessary for 
any reason any time during the study. In that case, all efforts should be made to perform the 
scheduled procedures and assessments for subjects who are still in the study until 12 weeks 
after the last dose. 
The study could be stopped or discontinued due to following reasons: 
• 
As per the DRC’s decision in Stage 1: 
- 
Any DLE identified as a safety concern (definition provided in Section 3.1.1.1); 
- 
Any clinically significant AE(s) identified as a safety concern (definition 
provided in Section 3.1.1.1); 
- 
For any other safety reason. 
• 
As per sponsor’s decision anytime during the study for reasons including: 
- 
Failure of the site staff to comply with the protocol or with the GCP guidelines; 
- 
AEs or SAEs leading to safety concerns (See Section 8.1.6); 
- 
Inadequate subject recruitment; 
- 
Other reasons (decisions made by the Regulatory Authorities or Ethics 
Committees or any other sponsor business decision). 
The subject withdrawal criteria as discussed in Section 4.4.

4.3 
Rationale for Inclusion/Exclusion Criteria 
In order to establish the preliminary efficacy of Dysport in this dose escalation and dose 
expansion study, a subset of vulvodynia subjects suffering from provoked vestibular pain is 
selected. It is hypothesised that pelvic floor muscle hypertonicity underpins the posterior 
vestibular pain experienced and consequently, these subjects are likely to respond to treatment 
with Dysport. Hence, the inclusion and exclusion criteria for this study have been tailored to 
ensure enrolment of female subjects with a confirmed diagnosis of PVD based on the three 
established criteria as per Pukall 2007 [21]: self-report of superficially-located pain during 
sexual intercourse; a lack of physical findings (e.g. infections) to explain the pain or the 
persistence of pain after conditions believed to be related to the pain have been treated; and a 
positive response (i.e. pain) during the cotton-swab test. This will also help target a 
homogenous subject population and limit intersubject variability. 
4.4 
Subject Withdrawal Criteria and Procedures 
In accordance with the Declaration of Helsinki (in accordance with the applicable country’s 
acceptance), each subject is free to withdraw from the study at any time. 
The investigator and/or sponsor can withdraw a subject at any time for any reason (e.g. 
protocol violation). 
The investigator also has the right to withdraw a subject from the study for reasons including: 
• 
If required by the DRC due to reasons described in Section 3.1.1.2 
• 
Any AE that jeopardises the safety of the subjects 
• 
Other reasons concerning the health or wellbeing of the subject 
• 
In the event of concurrent illness, based on the benefit risk for the subject as assessed 
by the investigator (see concomitant medications not permitted in Section 6.3) 
• 
Pregnancy (see Section 8.1.7) 
• 
Lack of cooperation in completing the study visits or schedules or study assessments 
• 
Study is stopped or discontinued (See Section 3.9 for further details) 
• 
Death (see Section 8.1.8) 
• 
Any other reason as judged by the investigator to be in the best interest of the subject. 
If a subject decides to withdraw from the study after administration of IMP, or should the 
investigator decide to withdraw the subject, all efforts will be made to complete and report the 
observations at least 12 weeks after the last dose or up to the time of withdrawal as thoroughly 
as possible. A complete assessment should be made and final evaluations be done at the time 
of the subject’s withdrawal as described in Section 5.2.4 with an explanation given of why the 
subject is withdrawing or being withdrawn from the study. 
 The reason for and date of withdrawal from the study must be recorded on the eCRF. If a 
subject withdraws consent, every attempt will be made to determine the reason. If the reason 
for withdrawal is an AE or a clinically significant laboratory test abnormality, monitoring will 
continue until the event has resolved or stabilised, until the subject is referred to the care of a 
local health care professional, or until a determination of a cause unrelated to the IMP or 
study procedure is made. The specific AE or test result(s) must be recorded on the eCRF. All 
evaluations should be performed, according to the protocol, on the last day the subject 
receives IMP, or as soon as possible thereafter.

STUDY PROCEDURES 
5.1 
Study Schedule 
The schedule of procedures and assessments during the study for the double-blind treatment 
period is summarised in Table 2 and for the open-label treatment period in Table 3. 
Subjects enrolled prior to implementation of Version 3.0 (dated 04 November 2018), i.e. 
subjects included in Cohort 1, will continue to follow the study assessments and procedures as 
per the protocol Version 2.0 (dated 15 May 2018). 
If the COVID-19 pandemic prevents subjects from coming to the site, subjects can have their 
study visit assessments performed remotely as judged appropriate by the investigator; the 
medical monitor/sponsor must be informed before implementing this. In such a case, the 
investigator will perform a telemedicine visit and will make every effort, where applicable, to 
contact the subject’s general practitioner or equivalent to ensure all important medical 
information and safety event(s) occurring since the last visit are collected. Guidance on how 
to collect protocol-planned assessments will be provided to the investigator in a separate 
document. Such document will be filed in the Trial Master File (TMF). IECs/IRBs will be 
notified of the changes as applicable locally. Of note, as the adapted visit deviates from the 
regular protocol plan, the changes will be recorded as protocol deviations related to 
COVID-19.

Study Visits 
For the purpose of study visits and procedures, the duration of 1 month=4 weeks=28 days. For 
assessments done at the Screening Visit, but not repeated at the Baseline Visit, the Screening 
values will be considered as Baseline.  
Subjects are required to remain at the clinic for the required duration of study assessments and 
for at least 30 minutes after study drug administration. 
The priority order for performing the assessments is discussed in Section 6.6. 
If the COVID-19 pandemic prevents subjects from coming to the site, study assessments 
planned in the protocol will be limited to the ones possible remotely, denoted with an 
asterisk (*) in Table 2, Table 3, Section 5.2.2, Section 5.2.3 and Section 5.2.4; of note no 
study assessments should be performed remotely for the Screening, Baseline and EOS/EWD 
visits. Completion of questionnaires on the subjects’ own device will be performed provided 
that the site staff can access the ePRO system to record the visit date. 
5.2.1 
Procedures for Screening and Enrolment - Visit 1 (Day -14 (-14 days/ +3 days)) 
A signed and dated informed consent form will be obtained before screening procedures. 
After informed consent is obtained, subjects who are screened will be allocated a subject 
number. All screened subjects must be identifiable throughout the study. The investigator will 
maintain a list of subject numbers and names to enable records to be found at a later date if 
required. 
5.2.1.1 
Screening – Visit 1 - Day -14 (-14 days/ +3 days) 
The Screening Visit (Visit 1) will take place on Day -14 of the study. The visit window will 
be from Day -28 to Day -11. 
The following assessments will be performed: 
• 
Eligibility check (inclusion/exclusion criteria) 
• 
Demographic data (year of birth, age, sex, ethnicity, and race)  
• 
Medical history, including significant ongoing medical history, surgical history and 
vulvodynia history 
• 
Vital signs (supine or sitting blood pressure and heart rate) 
• 
Body height and weight 
• 
Physical examination 
• 
Blood sampling (nonfasting) for haematology, biochemistry, putative antibodies and

A subject can be rescreened once, if all eligibility criteria were met but the subject was not 
enrolled due to any of the following, and twice due to ANY of the following conditions if 
they had to stop the first screening period due to COVID-19:  
• 
Cohort recruitment being complete by the time the subject was eligible,  
• 
If the subject had a UTI or vaginal infection at first screening and has received 
adequate treatment leading to complete resolution of the infection,  
• 
If the subject failed screening due to a selection criterion that was removed from the 
previous version of the protocol. If the subject failed screening due to a selection 
criterion that was modified, she should have fulfilled the new criterion at the time of 
the first screening to be able to be rescreened. In these situations, the subject may only 
be rescreened once the new amended protocol has been approved by the IRB.

Investigational Medicinal Product Preparation Storage and Accountability 
6.1.1 
Investigational Medicinal Product Storage and Security 
The investigator, or an approved representative (e.g. pharmacist), will ensure that all IMP and 
any other study related material is stored in a secured area, under recommended temperature 
monitored storage conditions, in accordance with applicable regulatory requirements. 
The IMP Dysport and the matching placebo should be stored at the recommended temperature 
(between 2°C and 8°C).  
The IMP Dysport and the matching placebo must not be frozen and should be protected from 
light. 
6.1.2 
Investigational Medicinal Product Preparation 
The investigator, or an approved representative (e.g. pharmacist), will ensure that all IMP is 
reconstituted and dispensed by qualified staff members according to the procedure detailed in 
the study IMP instructions. 
6.1.3 
Investigational Medicinal Product Accountability 
All IMP is to be accounted for on the IMP accountability log agreed with the sponsor.  
Any reconstituted unused IMP has to be discarded in accordance with local regulations (e.g. 
inactivation with sodium hypochlorite or autoclave, etc.). All disposal ancillary materials (e.g. 
needles and syringes) must be discarded in suitable containers intended for incineration after 
use at the site. Used/partly used and unused supplies must be retained for verification and 
accountability by the sponsor or sponsor’s representative prior to destruction. If used/partly 
used vials must be destroyed after use at the site as per local regulations, labelled empty boxes 
must be retained for verification and accountability. Supplies will be destroyed preferably at 
the site; if not, returned to the interim storage facility for destruction.

Reconstitution and Administration Procedure 
The study treatment will be reconstituted at the investigational site with preservative free 
0.9% sodium chloride for injection.  
The study treatment will be prepared by the investigator/pharmacist/designated personnel 
according to the instruction leaflet allocated for that treatment. Study treatment kits will be 
designed 
to 
maintain 
the 
blind 
and 
the 
person 
reconstituting 
the 
treatment 
(investigator/pharmacist/delegated personnel) as well as the subject will remain blinded to the 
treatment during the double-blind period. 
The process of reconstitution will vary based on the period of the study (double-blind or 
open-label) and the dose to be injected. Detailed instructions on reconstitution will be 
provided in the instruction leaflet. 
A total of 2.5 mL of the reconstituted study treatment will be administered intramuscularly at 
five predefined needle insertion points (A, B, C, D, E) at 10 injection sites (5 mm (superficial) 
and 10 mm (deep) depths at each needle insertion point) across four pelvic floor muscles 
(pubococcygeus, bulbospongiosus, superficial transverse perineal muscle and deep transverse 
perineal muscle) in the vestibular region as described below; the injection diagram is included 
in Figure 3. Regardless of the study period or the treatment group to which the subject is 
allocated, the volume of 2.5 mL will be constant across all dose groups.

6.3 
Concomitant Medication/Therapy 
Any prior or concomitant medications and therapy given to a subject before screening (as 
described in the screening procedures in Section 5.2.1) or during the study will be indicated 
on the eCRF.  
The following concomitant medications/therapies are not permitted during this study (see also 
Section 4.2): 
• 
Sex therapy (defined as a therapy primarily focused on the management of vulvar pain) 
up to 6 weeks after the first treatment cycle of the double-blind period. Any sex therapy 
initiated after this, needs to be maintained at the same frequency/regimen throughout 
the study. 
• 
Any form of BTX for administration into any other part/site of the body. 
• 
Any experimental new drug or device. 
• 
Illicit drugs. 
• 
The following medications that affect neuromuscular transmission: curare-like 
nondepolarising agents, lincosamides, polymyxins, anticholinesterases, aminoglycoside 
antibiotics (topical use is permitted except at the vulvar vestibular region), tizanidine 
and baclofen, within the past 4 weeks prior to Baseline and during the study.  
• 
Injections of steroids in the vulva should have been stopped 4 weeks prior to the 
Screening Visit and are not allowed during the study.  
• 
Topical lidocaine, topical antidepressants, topical anti-epileptics and diazepam 
suppositories are not permitted during the study. Note: Immediately prior to and during 
study drug administration procedures, oral, topical (including lidocaine) or 
intravenous/injectable medications routinely used as standard of care for vaginal 
intramuscular injections are allowed.  
• 
Medications that affect bleeding disorders (antiplatelet agents and/or anticoagulants) 
that might interfere with local injections or medications that contraindicate 
intramuscular injection. 
The following concomitant medications/therapies are permitted during this study, but they 
must be monitored closely and, where applicable, their dose and dose regimen should remain 
constant as detailed below: 
• 
Concomitant pelvic floor physical therapy is permitted. Subjects should maintain the 
dose regimen constant from 12 weeks prior to Baseline and throughout the first 
treatment cycle. 
• 
Concomitant use of topical treatments for vestibular pain with topical hormonal creams 
are permitted if the subject has no residual anterior vestibule pain at screening and 
wants to continue on the same treatment regimen throughout the study to prevent 
recurrence of anterior vestibular pain. Note: Topical antidepressants are not permitted. 
• 
Concomitant use of oral antidepressants, anxiolytics or anti-epileptics is permitted as 
long as the dose has remained stable for at least 6 months prior to the Screening Visit. 
Subjects should try to maintain the dose regimen constant throughout the first treatment 
cycle. 
• 
Concomitant use of anticholinergic drugs (which may potentiate systemic 
anticholinergic effects) is permitted if the dosage has been stable for the 6 weeks prior 
to Baseline and is expected to remain at this stable dose throughout the study.

• 
If concomitantly taking other analgesics, the subjects should make their best effort to 
stop them at the Screening Visit. If stopping of analgesic intake is not possible or 
indicated, then the intake needs to be maintained at a constant dose throughout 
1st treatment cycle and all details need to be captured in the eCRF.  
• 
Pain rescue medication taken to prevent or treat provoked vestibular pain should be 
avoided. If needed, the subject will be allowed to take Nonsteroidal Anti-inflammatory 
Drugs (NSAIDS) or Acetaminophen at the recommended dose as per need (PRN). The 
subject should attempt to use the same pain rescue medication throughout the study. 
Subjects will record the dosage and count (number of pills taken) in the eDiary for the 
analgesic taken prior or after intercourse to prevent or treat vestibular pain 
(Section 7.4.2.5). However, the subject should refrain from taking any rescue 
medication within 24 hours of a study visit.  
During Stage 2, if required, the subject will be permitted to take from the following pain 
rescue medications listed in Table 7 at regular strength per approved labelling (recommended 
dose); these medications (i.e. Aspirin, Acetaminophen, Naproxen or Ibuprofen) are available 
over the counter (OTC).

• 
Concomitant medications for other purposes are allowed at the investigator’s 
discretion. It is recommended that the dosage for these medications is kept constant 
throughout the study. Where medically appropriate, all concomitant medications being 
taken by a subject at entry into the study should continue at the same dose. 
6.4 
Lifestyle Restrictions/Recommendations 
Subjects will be requested to comply with the restriction criteria related to alcohol 
consumption and drugs of abuse, presented as exclusion criteria in Section 4.2. 
Subjects will be instructed to avoid vulvar irritants such as perfumes, deodorants, or soaps and 
will be encouraged to avoid modifying hygiene habits during the study. The subject should be 
instructed to wear only cotton underwear. 
6.5 
Procedures for Monitoring Subject Compliance 
The investigator will be responsible for monitoring subject compliance. Subjects can be 
withdrawn from the study at any time if the investigator or the sponsor determines that the 
subject is not in compliance with the study protocol.

Study Drug will be administered at the clinic by the investigator, thus, subject compliance 
with treatment is not expected to be an issue. Drug accountability records will be maintained 
by the investigator documenting that subject received allocated drug. 
6.6 
Priority Order on Study Procedures 
The following priority order should be followed in case study procedures are scheduled at the 
same time point: 
(1) 
The subject needs to complete the questionnaires at the site (PCS, mFSFI, PHQ-9, 
mVPAQ, SF-36) and subsequently complete the PGI-S and PGI-C assessments prior to 
seeing the investigator.  
(2) 
Interview and clinical examination by the investigator. 
(3) 
When doing the clinical examination, the investigator needs to conduct the dilator test 
prior to the measurement of pelvic floor muscles pressure. 
(4) 
For visits, other than the screening, CGI should be assessed by the investigator after all 
other clinical assessments have been performed.

Methods and Timing of Assessing, Recording, and Analysing Efficacy Data 
Methods for assessing efficacy data are described below. Timing of efficacy assessments are 
presented in Table 2 and Table 3, and discussed in Section 5.2. Procedures for recording 
efficacy data are discussed in Section 15.1, and methods of analyses are discussed in 
Section 11.4.3. The priority order for performing the assessments is discussed in Section 6.6. 
All efforts should be made to have the same investigator perform the clinical examinations for 
a given subject, at least for the Screening, Baseline, and Week 6 Visits of the first treatment 
cycle. 
The Sponsor will provide a device to complete the e-diary questionnaires in the study if 
requested by subjects or in situations in which the subject is not willing or able to use their 
own device. The device will be returned to the site at the completion of the subjects’ 
participation in the study. 
7.4.1 
Dilator Test (Vaginal Dilator Induced Pain) 
A set of 8 vaginal dilators of increasing diameter (#1 being the smallest and #8 being the 
largest) will be used to provoke pain to allow assessment of the vestibular pain intensity in 
each subject. At each visit, the investigator will insert the dilator between 3 to 4 cm depth in 
the vagina starting with the smallest sized dilator and progressively increasing the size of the 
dilator. No lubricant, other than water, may be used when inserting the dilator. In order to 
standardise the methodology each dilator should be inserted for a period of 5 to 10 seconds 
and the time period between the insertion of two dilators should be 30 seconds to 1 minute. 
Subjects will be required to rate the pain for each dilator size on an 11-point NRS (Figure 4) 
at each visit. Based on the subjective pain threshold, the largest sized dilator that the subject 
accepts/tolerates for the test (i.e. does not agree to the next successive dilator size to be 
tested), will be defined as the Dilator Maximum Tested Size (DMTS) that will be established 
at Baseline Visit. The dilator test will be used to assess the change from Baseline in the 
vaginal dilator induced pain as reported on a NRS (using the DMTS reported at baseline) as 
well as the dilator size that provokes maximum tolerated pain.  
Figure 4 Numeric Pain Rating Scale 
 
Subject interviews to assess the content relevance of the dilator test will be performed in 
Stage 2. Subjects from Stage 2 will be invited to complete the interview until the target 
sample of 20 subjects is achieved. Every effort should be made to conduct the interview 
within 2 weeks of the subject’s Cycle 1-Week 6 visit.

The subject interviews will be conducted by experienced interviewers trained in qualitative 
interview techniques. The details of the interview will be provided in the interview guide. 
7.4.2 
Patient Reported Questionnaires and Assessments 
In order to ensure accurate and unbiased subject questionnaire completion, the following 
guidelines should be adhered to: 
• 
The questionnaires should be completed by the subject (with the caregiver's assistance, 
if necessary), at the beginning of the site visit prior to having the interview with the 
investigator. 
• 
Study site personnel should not change responses on the questionnaires.  
An electronic Patient-Reported Outcome (ePRO) device will be used to complete the 
questionnaires (programmed in a predefined sequence) as well as to record data in the eDiary 
contributing towards completion of particular questionnaire subscales and efficacy endpoints. 
Timing of efficacy assessments are presented in Table 2 and Table 3. 
7.4.2.1 
Modified Vulvar Pain Assessment Questionnaire (mVPAQ)  
The Vulvar Pain Assessment Questionnaire (VPAQ) is a more recently developed, 
self-administered, 
multidimensional, 
vulvodynia 
specific 
questionnaire, 
including 
55 Likert-type questions and designed to capture 6 domains: pain severity, emotional 
response, 
cognitive 
response 
and 
interference 
with 
life, 
sexual 
function, 
self-stimulation/penetration [22]. The score for each question ranges from 0 to 4 and a mean 
score is computed for each domain.  
For the purpose of the study, the VPAQ subscales will be modified as: 
• 
mVPAQ pain subscale – The recall period will be over the past 1 week.  
• 
mVPAQ life interference subscale – The recall period will be over the past 1 week.  
• 
mVPAQ other subscales – The recall period will be over the past 1 month. 
• 
The sequence of questions for reporting distress (average/ worst) on the pain severity 
subscale were reversed. 
The mVPAQ questionnaire is included in Appendix 1. 
The data to be recorded by subjects in the eDiary contributing towards the completion of the 
questionnaire: 
• 
mVPAQ pain subscale – Assessed at Screening Visit, then 1 week prior to the next 
planned visit and at the visit. 
• 
mVPAQ life interference subscale – Assessed at Screening Visit, then 1 week prior to 
the next planned visit and at the visit. 
• 
mVPAQ other subscales – Assessed at the site during the visit (except Additional 
Visits at Week 18 and Week 30). 
7.4.2.2 
Assessment of Intercourse and Vaginal Dilator (Number 6 Size) Insertion Details 
From the Screening Visit (Day -14; i.e. during the screening period), and then 2 weeks 
(14 days) prior to the next planned visit, subjects will record on a daily basis in the eDiary 
(contributing to collection of data for the corresponding endpoint): 
• 
If they had intercourse and if yes, the number of intercourse instances in the previous 
24-hour period;  
• 
Rate the level of the corresponding pain during each intercourse instance on an 
11-point NRS;

• 
Details of pain rescue medication consumed for each intercourse instance (yes/no; if 
yes - type, dose, frequency, route, duration) to prevent or treat the vestibular pain. 
From 2 weeks prior to the next planned visit, all subjects are to rate in the eDiary once a week 
the level of the corresponding pain following insertion of the number 6 vaginal dilator into the 
vagina on an 11-point NRS and record details of associated pain medication if consumed. 
Assessment on the day of the visit should be avoided. 
7.4.2.3 
Modified Female Sexual Function Index (mFSFI) 
The FSFI is a validated self-reported multidimensional 19-item questionnaire for assessing 
the sexual function in women by evaluating six key domains of sexual function: desire, 
arousal, lubrication, orgasm, sexual satisfaction, and pain.  
A total score and domain scores will be calculated. Every item is assessed with a score from 0 
or 1 to 5, the total score being 2-36.  
For the purpose of the study, the recall periods for FSFI pain domain (Questions 17 to 19) will 
be modified as: 
• 
mFSFI pain domain – The recall period will be over the past 1 week.  
• 
mFSFI other domains – The recall period will be over the past 4 weeks. 
From Stage 2 onwards, Question 19 of the pain domain (measuring the level of pain ‘during’ 
and ‘following’ vaginal penetration with a 1-week recall period) will be split into two separate 
questions –  
• 
Question 19 – measuring the level of discomfort or pain during vaginal penetration. 
• 
Question 20 – measuring the level of discomfort or pain following vaginal penetration. 
The mFSFI questionnaire is included in Appendix 2. 
The data to be recorded by subjects in the eDiary contributing towards the completion of the 
questionnaire: 
• 
mFSFI pain domain – Assessed at Screening Visit, then 1 week prior to the next 
planned visit and at the visit. 
• 
mFSFI other domains – Assessed at the site during the visit. 
7.4.2.4 
Patient Global Impression (PGI) 
7.4.2.4.1 Patient Global Impression of Severity (PGI-S) of the Provoked Vulvar Pain  
An assessment of patient global impression of severity (PGI-S) of the pain will be conducted 
by the subject using a 4-point Likert scale (from 0: no pain to 3: severe pain). 
The PGI-S will be assessed by the subject by answering the following question: “How severe 
was your ‘provoked vulvar pain’ (pain specifically triggered by touching the vulvar area) over 
the past week?  
9 = not assessable due to lack of circumstances causing provoked pain  
0 = no pain 
1 = mild pain 
2 = moderate pain 
3 = severe pain.”

7.4.2.4.2 Patient Global Impression of Change (PGI-C) in the Provoked Vulvar Pain  
An assessment of global impression of change in pain will be conducted by the subject using 
a 7-point Likert scale (from -3: very much worse to +3: very much improved). 
The PGI-C will be assessed by the subject by answering the following question: “Compared 
to your provoked vulvar pain at Baseline i.e. prior to the study treatment initiation, your 
provoked vulvar pain is:  
+3 = very much improved  
+2 = much improved 
+1 = minimally improved 
 0 = no change from baseline 
-1 = minimally worse 
-2 = much worse  
-3 = very much worse.” 
7.4.2.5 
Use of Pain Rescue Medications  
As discussed in Section 7.4.2.2 subjects will record in the eDiary the details of pain 
medication taken to prevent or treat the pain during intercourse and/or dilator insertion.  
The type, dose and frequency of pain rescue medication intake will be analysed. 
7.4.2.6 
Patient Health Questionnaire (PHQ-9) 
The PHQ-9 is an easy-to-use, validated questionnaire to measure the severity of depression 
(Appendix 3). The response to treatment is scored for each of the nine DSM-IV (Diagnostic 
and Statistical Manual of Mental Disorders) criteria as "0" (not at all) to "3" (nearly every 
day) providing a total score being 0 to 27. Scores of 5, 10, 15, and 20 represent cut-off points 
for mild, moderate, moderately severe and severe depression, respectively. 
7.4.2.7 
36-Item Short Form Health Survey (SF-36) 
The SF-36 is a validated set of generic, coherent, and easily administered QoL measures 
(Appendix 4). These measures rely upon patient self-reporting and are now widely utilised by 
managed care organisations and by for routine monitoring and assessment of care outcomes in 
adult patients.  
The SF-36 has eight scaled scores; the scores are weighted sums of the questions in eight 
health concepts: physical functioning, bodily pain, role limitations due to physical health 
problems, role limitations due to personal or emotional problems, emotional well-being, 
social functioning, energy/fatigue, and general health perceptions.  
The total scores range from 0 to 100. Lower scores indicate a less favourable health state and 
higher scores a more favourable health state. 
7.4.2.8 
Pain Catastrophizing Scale (PCS) 
The PCS is a widely used, validated 13-item scale assessing the state of mind of subjects in 
pain through a comprehensive evaluation that encompassing the different perspectives on 
catastrophizing (Appendix 5). It is a self-administered questionnaire in which the subjects 
answer questions about how they feel and what they think about when they are in pain. Each 
item rated on a 5-point scale: 0 (not at all) to 4 (all the time). A total score, ranging from 0 to 
52 (sum of the 13 items) will be calculated.

Investigator-Reported Assessments  
7.4.3.1 
Q-tip 
The Q-tip test, also known as the Cotton Swab test, is a widely used standard test to diagnose 
PVD, i.e. to assess the vestibular pain provoked by touch. A cotton swab/ cotton-tipped 
applicator will be used randomly to palpate all vulvar vestibular sites and the corresponding 
pain will be assessed [7, 25].  
The Q-tip test will be performed to screen the subjects but will not be an assessment of the 
efficacy of the study drug.  
7.4.3.2 
Clinical Global Impression (CGI)  
An assessment of global impression of treatment response will be conducted by the 
investigator using a 7-point Likert scale (from -3: very much worse to +3: very much 
improved). 
The CGI will be assessed by the investigator by answering the following question: ‘Compared 
to the subject’s condition at Baseline i.e. prior to the study treatment initiation, your subject’s 
condition is:  
+3 = very much improved;  
+2 = much improved;  
+1 = minimally improved; 
0 = no change from baseline; 
-1 = minimally worse;  
-2 = much worse;  
-3 = very much worse.” 
7.4.3.3 
Measurement of Pelvic Floor Muscle Pressure 
The resting vaginal pressure and maximal ‘squeeze’ pressure will be measured using a CE 
marked medical device in all subjects in Stage 1 up to 400 U and in a subset of subjects in 
Stage 2 who have never had vaginal delivery (included attempted vaginal delivery), and at 
study sites that were provided a perineometer. Three measures of resting vaginal pressure and 
three measures of maximal ‘squeeze’ vaginal pressure should be performed. The time period 
between each measure performed for either the resting or maximal ‘squeeze’ vaginal pressure 
should be 30 seconds to 1 minute. Each squeeze while performing the maximal ‘squeeze’ 
vaginal pressure should last for 5 seconds. 
Further instructions will be provided in the Study Manual.

ASSESSMENT OF SAFETY 
8.1 
Adverse Events 
Adverse events will be monitored from the time that the subject gives informed consent and 
throughout the study until the end of study.  Information will be elicited by direct, nonleading 
questioning or by spontaneous reports. Further details for AE reporting can be found in 
Section 8.1.2. 
The investigator will be responsible for a clinical assessment of the study participants during 
the whole participation of the subjects in the study, from informed consent up to discharge 
from the study, and for the setup of a discharge plan if needed.  
The sponsor medical monitor and the GPS physician will monitor safety data throughout the 
course of the study. 
8.1.1 
Definition of an Adverse Event 
An AE is the development of an undesirable medical condition or the deterioration of a 
pre-existing medical condition following or during exposure to a pharmaceutical product, 
whether or not considered causally related to the product. An undesirable medical condition 
can be symptoms (e.g. nausea, chest pain), signs (e.g. tachycardia, enlarged liver) or the 
abnormal results of an investigation (e.g. laboratory findings, electrocardiogram). In clinical 
studies an AE can include an undesirable medical condition occurring at any time, including 
run in or washout periods, even if no IMP has been administered.  
This definition includes events occurring from the time of the subject giving informed consent 
until the end of the study (as defined in Section 3.8). 
8.1.2 
Categorisation of Adverse Events 
8.1.2.1 
Intensity Classification 
Adverse events will be classified as mild, moderate or severe according to the following 
criteria: 
• 
Mild: symptoms do not alter the subject’s normal functioning 
• 
Moderate: symptoms produce some degree of impairment to function, but are not 
hazardous, uncomfortable or embarrassing to the subject 
• 
Severe: symptoms definitely hazardous to wellbeing, significant impairment of 
function or incapacitation. 
8.1.2.2 
Causality Classification 
The relationship of an AE to IMP administration will be classified according to the following: 
• 
Related: reports including good reasons and sufficient information (e.g. plausible time 
sequence, dose response relationship, pharmacology, positive dechallenge and/or 
rechallenge) to assume a causal relationship with IMP administration in the sense that it 
is plausible, conceivable or likely. 
• 
Not 
related: 
reports 
including 
good 
reasons 
and 
sufficient 
information 
(e.g. implausible time sequence and/or attributable to concurrent disease or other drugs) 
to rule out a causal relationship with IMP administration. 
8.1.2.3 
Assessment of Expectedness 
The reference safety information for assessing expectedness of AEs/event in this study will be 
in the current IB.

8.1.2.4 
Laboratory Test Abnormalities 
Abnormalities in laboratory test values should only be reported as AEs if any of the following 
apply:  
• 
They result in a change in IMP schedule of administration (change in dosage, delay in 
administration, IMP discontinuation), 
• 
They require intervention or a diagnosis evaluation to assess the risk to the subject, 
• 
They are considered as clinically significant by the investigator. 
8.1.2.5 
Abnormal Physical Examination Findings  
Clinically significant changes, in the judgement of the investigator, in physical examination 
findings (abnormalities) will be recorded as AEs.  
8.1.2.6 
Other Investigation Abnormal Findings 
Abnormal test findings as judged by the investigator as clinically significant 
(e.g. electrocardiogram changes, thyroid function disturbances) that result in a change in 
study drug dosage or administration schedule, or in discontinuation of the study drug, or 
require intervention or diagnostic evaluation to assess the risk to the subject, should be 
recorded as AEs.  
8.1.3 
Clinically Significant Adverse Events and Dose Limiting Events 
Definitions for identification of a clinically significant AE and a DLE for this study is 
provided in Section 3.1.1.1. 
Details of DRC meetings and the management of dose escalation of the cohorts by the DRC 
are provided in Section 3.1.1.2 
8.1.4 
Adverse Events of Special Interest 
The effects of Dysport and all BTX products may spread from the area of injection to produce 
symptoms consistent with the pharmacology of BTX. These symptoms have been reported 
hours to weeks after injection. Remote spread of toxin that affects swallowing and breathing 
can be life threatening, and there have been reports of death. The risk of symptoms is 
increased in subjects who have underlying conditions (e.g. disorders of the neuromuscular 
junction) that would predispose them to these symptoms. Dysport is contraindicated in 
individuals with known hypersensitivity to any BTX preparation or to any of the components 
in the formulation.  
Adverse events of special interest (AESIs) for Dysport in this study are defined as: 
• 
Any TEAE that suggest a possible remote spread of effect of the toxin or  
• 
Any TEAE related to urinary incontinence or faecal incontinence or  
• 
Any TEAE assessed as a potential hypersensitivity reaction,  
where there is a reasonable possibility of causal relationship with treatment with Dysport, 
regardless of the investigator reported causality. A list of Medical Dictionary for Regulatory 
Activities (MedDRA) preferred terms (PTs) that will be used to identify potential AESIs is 
provided in the statistical analysis plan (SAP). The list of PTs that is used by the sponsor to 
identify events suggestive of remote spread of toxin includes the terms compatible with the 
mechanism of action of BTX-A-HAC, is based on recommendations from the US Food and 
Drug Administration (US FDA) (Guidance for Industry: upper facial lines botulinum toxin 
products (Appendix A)) and the EU Committee for Medicinal Products for Human Use 
(CHMP) (Joint Assessment Report on definition of toxin spread). All AE PTs retrieved using 
this list of MedDRA PTs will be manually reviewed and medically evaluated by the sponsor

to determine to determine if there is a plausible possibility that they represent remote spread 
of toxin or suggestive of hypersensitivity reaction due to Dysport treatment. In order to 
perform the analysis, variables including alternate aetiology (medical history, concomitant 
medications, or diagnosis which could account for the symptoms), location of Dysport 
administration, and temporal relationship to IMP administration will be considered by the 
sponsor. 
8.1.5 
Recording and Follow-up of Adverse Events 
At each visit, the subject should be asked a nonleading question such as: “How have you felt 
since starting the new treatment/last dose/the last assessment?” 
All observed or volunteered AEs, regardless of treatment group or suspected causal 
relationship to IMP, will be recorded on the AE page(s) of the eCRF. Events involving drug 
reactions, accidents, illnesses with onset during the treatment phase of the study, or 
exacerbations of pre-existing illnesses should be recorded. 
Any AEs already recorded and designated as ‘continuing’ should be reviewed at each 
subsequent assessment. 
For all AEs, the investigator must pursue and obtain information adequate both to determine 
the outcome of the AE and to assess whether it meets the criteria for classification as a SAE 
requiring immediate notification to the sponsor or its designated representative. For all AEs, 
sufficient information should be obtained by the investigator to determine the causality of the 
AE (i.e. IMP or other illness). The investigator is required to assess causality and record that 
assessment on the eCRF. Follow-up of the AE, after the date of IMP discontinuation, is 
required if the AE or its sequelae persist. Follow-up is required until the event or its sequelae 
resolve or stabilise at a level acceptable to the investigator and the sponsor’s clinical monitor 
or his/her designated representative. 
8.1.6 
Reporting of Serious Adverse Events 
All SAEs (as defined below) regardless of treatment group or suspected relationship to IMP 
must be reported immediately (within 24 hours of the investigator’s knowledge of the event) 
using the fax number or email address specified at the beginning of this protocol. If the 
immediate report is submitted by telephone, this must be followed by detailed written reports 
using the SAE report form. 
A SAE is any AE that: 
(1) 
Results in death, 
(2) 
Is life threatening, that is any event that places the subject at immediate risk of death 
from the event as it occurred. It does not include an event that, had it occurred in a 
more severe form, might have caused death, 
(3) 
Results in in-patient hospitalisation or prolongation of existing hospitalisation, 
excluding admission for social or administrative reasons (see further), 
(4) 
Results in a persistent or significant disability/incapacity, where disability is a 
substantial disruption of a person's ability to conduct normal life functions, 
(5) 
Results in congenital anomaly/birth defect in the offspring of a subject who received 
the IMP, 
(6) 
Is an important medical event that may not result in death, be life threatening, or 
require hospitalisation when, based upon appropriate medical judgement, may 
jeopardise the subject and may require medical or surgical intervention to prevent one 
of the outcomes listed in this definition. 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 in-patient hospitalisation, or the 
development of drug dependency or drug abuse. 
In addition to the above criteria, any additional AE that the investigator considers serious 
should be immediately reported to the sponsor and included in the corporate SAEs database 
system. This includes any suspected or confirmed coronavirus COVID-19 (SARS-CoV-2) 
infection (seriousness criteria should be “other medically significant” if no other seriousness 
criteria are present (e.g. hospitalisation)). 
• 
Hospitalisation is defined as any in-patient admission (even if less than 24 hours). For 
chronic or long term in-patients, in-patient admission also includes transfer within the 
hospital to an acute/intensive care in-patient unit. 
• 
Prolongation of hospitalisation is defined as any extension of an in-patient 
hospitalisation beyond the stay anticipated/required in relation to the original reason for 
the initial admission, as determined by the investigator or treating physician. For 
protocol-specified hospitalisation in clinical studies, prolongation is defined as any 
extension beyond the length of stay described in the protocol. Prolongation in the 
absence of a precipitating, treatment emergent, clinical AE (i.e. not associated with the 
development of a new AE or worsening of a pre-existing condition) may meet criteria 
for "seriousness" but is not an adverse experience and thus is not subject to immediate 
reporting to the sponsor.  
• 
Preplanned or elective treatments/surgical procedures should be asked for and 
documented in the subject’s screening records. Hospitalisation for a preplanned or 
elective treatment/surgical procedure should not be reported as an SAE unless there are 
complications or sequelae which meet the criteria for seriousness described above. 
Any SAE must be reported immediately (within 24 hours), using the fax number or e-mail 
address specified at the beginning of this protocol, independent of the circumstances or 
suspected cause, if it occurs or comes to the attention of the investigator at any time during 
the study period. 
Any AE/SAE with a suspected causal relationship to IMP administration occurring at any 
other time after completion of the study must be promptly reported. 
The following information is the minimum that must be provided to the sponsor within 24 
hours for each SAE: 
• 
Study number 
• 
Centre number 
• 
Subject number 
• 
AE 
• 
Causality 
• 
Investigator's name and contact details 
The additional information included in the SAE form must be provided to the sponsor or 
representative as soon as it is available. The investigator should always provide an assessment 
of causality for each event reported to the sponsor. Upon receipt of the initial report, the 
sponsor will ask for the investigator's causality assessment if it was not provided with the 
initial report.

The investigator should report a diagnosis or a syndrome rather than individual signs or 
symptoms. The investigator should also try to separate a primary AE considered as the 
foremost untoward medical occurrence from secondary AEs which occurred as complications. 
8.1.7 
Pregnancy 
Pregnancy itself is not regarded as an AE unless there is a suspicion that the IMP has 
interfered with a contraceptive method. If pregnancy occurs during the study, the outcome of 
the pregnancy will then need to be collected even if this occurs after the end of the study and 
the subject will not receive any further administration of the IMP.  
Information regarding pregnancies must be collected on the AE page of the eCRF and on the 
Standard Pregnancy Report Form, including pregnancies with normal progress and outcome. 
A Standard Pregnancy Report Form must be completed by the investigator and provided to 
the Sponsor’s Pharmacovigilance department within 24 hours of the knowledge of the 
pregnancy in any study subject. The sponsor will request further information from the 
investigator as to the course and outcome of the pregnancy using the Standard Pregnancy 
Outcome Report Form.  
The investigator must instruct all female subjects to inform them immediately should they 
become pregnant during the study. The investigator should counsel the subject, discuss the 
risks of continuing with the pregnancy and the possible effects on the foetus. Monitoring of 
the subject should continue until conclusion of the pregnancy, which may involve follow-up 
after the subject’s involvement in the study has ended. 
Pregnancies with a conception date during the study participation or within 12 weeks after 
subject’s last dose of IMP must also be reported to the investigator for onward reporting to the 
sponsor. 
8.1.8 
Deaths 
All AEs resulting in death either during the study period or within 12 weeks (84 days) after 
the last dose of IMP, must be reported as an SAE within 24 hours of the investigator’s 
knowledge of the event.  
The convention for recording death is as follows:  
• 
Adverse event term: lead cause of death (e.g. multiple organ failure, pneumonia, 
myocardial infarction), 
• 
Outcome: fatal. 
The only exception is if the cause of death is unknown (i.e. sudden or unexplained death), in 
which case the AE term may be “death” or “sudden death.”

distinguished 
from 
discontinuation/withdrawal due to insufficient response to the IMP (see Section 4.4). 
If the IMP is discontinued due to a SAE, it must be reported immediately to the sponsor’s 
designated representative (see Section 8.1.6). 
In all cases, the investigator must ensure the subject receives appropriate medical follow-up 
(see Section 8.1.5).  
In case of suspected or confirmed COVID-19 infection which is to be reported as an SAE 
(Section 8.1.6), the IMP administration may be temporarily postponed depending on the 
subject clinical presentation. In some cases, the investigator may request a subject be retested 
before the IMP administration.

Reporting to Competent Authorities (CAs)/IECs/IRBs/Other Investigators 
The sponsor will ensure that processes are in place for submission of reports of Suspected 
Unexpected Serious Adverse Reactions occurring during the study to the CAs, IECs and other 
investigators concerned by the IMP. Reporting will be done in accordance with the applicable 
regulatory requirements. 
For study centres in the USA, Investigational New Drug Application Safety Reports will be 
submitted directly to the investigators. It is the investigators’ responsibility to notify their IRB 
in a timely manner. 
8.2 
Clinical Laboratory Tests 
Blood samples will be collected for the evaluation of haematology, serum chemistry, FSH, 
and putative antibodies. Full details regarding the clinical tests are provided in the Study 
Manual. 
A vaginal swab will be taken and analysed locally to detect possible infection.  
Urine samples will be collected for the evaluation of illicit drugs and pregnancy and analysed 
at the study site.  
The schedule of assessments is detailed in Section 5.1. 
The investigator will review the safety laboratory test results, document the review, and 
record any clinically relevant changes occurring or observed during the study in the AE 
section of the eCRF (see Section 8.1.2.4 for abnormal laboratory tests that should be recorded 
as AEs). 
All clinically relevant abnormal laboratory tests occurring during the study will be repeated at 
appropriate intervals until they return to Baseline or to a level deemed acceptable by the 
investigator and the sponsor’s clinical monitor (or his/her designated representative) or until 
the abnormality is explained by an appropriate diagnosis.

STATISTICS 
Detailed methodology for summary and statistical analyses of the data collected in this study 
will be documented in a SAP, which will be dated and completed before the database lock of 
the intermediate analysis (described in Section 11.6). The SAP may modify the plans outlined 
in the protocol; however, any major modifications of the primary endpoint and/or its analysis 
will be reflected either in a protocol amendment or in a dedicated CSR section. 
Statistical evaluation will be performed using Statistical Analysis System (SAS)® (version 9.1 
or higher). 
The COVID-19 pandemic may have an impact on this trial and specific summaries will be 
provided in order to assess its impact. 
11.1 
Analyses Populations 
The following populations will be used during statistical analyses for Stage 1 and Stage 2: 
• 
Screened population: All subjects screened (i.e. who signed the informed consent). 
• 
Randomised population: All subjects randomised (i.e. who were randomly allocated 
to a treatment group). 
• 
Safety population: All randomised subjects who received at least one dose of IMP 
administration (including only partial administration). 
• 
modified Intent-to-Treat (mITT) population: All randomised subjects who received 
at least one IMP administration and had data for the primary endpoint at Baseline and 
Cycle 1-Week 6 visit (i.e. at least one pain score for one dilator size).  
• 
Per protocol (PP) population: All subjects in the mITT population for whom no 
major protocol deviations, which may interfere with the efficacy evaluation, occurred 
between Screening and Cycle 1-Week 6 included. 
11.1.1 
Populations Analysed 
In Stage 1, the primary analysis based on safety endpoints will be performed on the 
Safety population. Analyses of efficacy endpoints will be carried out on the mITT population. 
In Stage 2, the primary efficacy analysis based on efficacy endpoints will be performed on the 
mITT and PP population. Secondary analyses on efficacy endpoints will be carried on the 
mITT population. 
The analyses of safety data will be performed based on the safety population. 
11.1.2 
Reasons for Exclusion from the Analyses 
Any major protocol deviation (see Section 13.1.2 for definition) will be described. Subjects 
substantially affected directly or indirectly by COVID-19 will be flagged with a major 
protocol deviation.  
The final list of protocol deviations impacting the PP population will be reviewed prior to 
database lock, before unblinding of treatment groups for the intermediate and primary 
analysis (with the exception of DRC, which may/ may not request unblinding (see 
Section 3.1.1.2). The list may be updated, up to the point of database lock, to include any 
additional major protocol deviations impacting inclusion in the PP population.

11.2 
Sample Size Determination 
Stage 1:  
In Stage 1, the expected sample size is 10 evaluable subjects for PVD2 cohorts who will be 
randomised and treated in a 4:1 allocation ratio (Dysport or Placebo), and 8 evaluable subjects 
for PVD1 Cohort 4 treated in a 3:1 allocation ratio (Dysport or Placebo). 
After Cohort 3 (PVD2) and Cohort 4 (PVD1), the expected sample size is 10 evaluable 
subjects for additional PVD1 and PVD2 cohorts and treated in a 4:1 allocation ratio (Dysport 
or Placebo).  
Subject who discontinue prior to Week 6 for reasons unrelated to safety may be replaced at 
the discretion of the investigator and sponsor. As this is an exploratory stage, no formal power 
could be performed. However, with 8 active subjects per PVD2 dose cohort and if there are 
0 DLEs in a cohort, there is at least 80% probability that the true incidence of DLEs at the 
corresponding dose will not be greater than 18%. With 16 active subjects in PVD1 and PVD2 
dose cohorts and if there are 0 DLEs in a cohort, there is at least 80% probability that the true 
incidence of DLEs at the corresponding dose will not be greater than 9%. The ability to rule 
out smaller DLE rates with high confidence will come from observing additional subjects in 
Stage 2.  
Stage 2: 
The study sample size required to have at least 80% power to detect a 2-point improvement 
for an experimental drug arm relative to placebo on mean change from baseline to Week 6 in 
the vaginal dilator induced pain as reported on a numeric pain rating scale (using the DMTS) 
using a one-sided 0.10 level test (not corrected for multiplicity) is 21 evaluable subjects per 
arm (i.e. a total of 63 subjects). The following assumptions were used for the power 
statement:  
• 
Expected outcome on the mean change from baseline to Week 6 in the vaginal dilator 
induced pain as reported on a numeric pain rating scale in the placebo group = 2-point 
decrease (reference approximated by VAS per speculum in Bornstein, 2010 [26])  
• 
Expected outcome on the mean change from baseline to Week 6 in the vaginal dilator 
induced pain as reported on a numeric pain rating scale in a Dysport treated 
group = 4-point decrease  
• 
Expected common standard deviation of the mean change from baseline to Week 6 in 
the vaginal dilator induced pain as reported on a numeric pain rating scale = 3-points 
(approximated per VAS data in Table 2 in Davis 2013 [27]). 
Subject who discontinue prior to Week 6 for reasons unrelated to safety will be replaced at the 
discretion of the investigator and sponsor. 
At the end of Stage 2, if the true DLE rate is 6% or greater, there is at least 80% probability to 
observe at least 1 DLE in 29 subjects (8 in Stage 1 and 21 in Stage 2). Therefore, if there are 
no observed DLEs in both Stage 1 and Stage 2 at a dose level, then there is good confidence 
that the true DLE rate is no more than 6%. If the dose chosen in Stage 2 has been tested on 
two cohorts (PVD1 and PVD2) in Stage 1, at the end of Stage 2, if the true DLE rate is 5% or 
greater, there is at least 80% probability to observe at least one DLE in 37 subjects (16 in 
Stage 1 and 21 in Stage 2). Therefore, if there are no observed DLEs in both Stage 1 and 
Stage 2 at a dose level, then there is good confidence that the true DLE rate is no more than 
5%. If it is reasonable to assume that the relationship between toxicity and dose level is 
monotonic non-decreasing, then we may pool dose levels to obtain a higher degree of 
confidence for the lower dose level.

Following the review of data available from Stage 1, the sample size may be formally 
recalculated for Stage 2 after the intermediate analysis. 
11.3 
Significance Testing and Estimations 
Stage 1: 
As this is a descriptive safety study, no formal statistical testing will be carried out. P-values, 
unadjusted for multiple comparisons, may be presented, but they will be regarded as 
descriptive.  
Stage 2: 
All statistical tests will be performed at a one-sided significance level of 10%. 
11.4 
Statistical/Analytical Methods 
Statistical analyses will be performed by an external CRO, managed by the sponsor’s 
biometry department. 
All analyses will be provided by stages. In addition, within each stage, the double-blind and 
open-label periods will be separately analysed. For doses that are selected for Stage 2, safety 
data may be pooled and summarised. 
11.4.1 
Demographic and Other Baseline Characteristics 
In order to evaluate balance of treatment groups, descriptive summary statistics (n, mean, 
standard deviation (SD), median, minimum, maximum) or frequency counts of demographic 
and baseline data (medical history, concomitant disease, etc.) will be presented by treatment 
group. 
In Stage 1, main demographic and baseline characteristics will be provided in patients 
recruited before and after the start of COVID-19 pandemic (i.e. before / after first patient 
randomised in Cohort 6) in order to identify a potential change in the general patients’ 
characteristics. 
11.4.2 
Subject Disposition and Withdrawals 
The numbers and percentages of subjects screened, randomised and included in the analysis 
populations will be tabulated. The reasons for subject exclusions from each of the populations 
will also be tabulated. In addition, the numbers of subjects who discontinued and completed at 
each of the study periods (double-blind treatment period and open-label period) will be 
tabulated. Primary reasons for discontinuation of study treatment will be tabulated. 
The impact of COVID-19 pandemic on the trial will be assessed through the summary of data 
collected in relation to COVID-19, i.e. disposition of patients including the proportion of 
patients impacted and withdrawn due to COVID-19 pandemic and number of patients with 
visits impacted by COVID-19 with the corresponding reason. Exposure to treatment will also 
be described before and after the start of COVID-19 pandemic (i.e. before/after first patient 
randomised in Cohort 6). 
11.4.3 
Efficacy Evaluation 
Stage 1: 
The primary objective and endpoint of the Stage 1 is the safety assessments.  
Descriptive statistics will be performed on the safety and efficacy endpoints.

Stage 2: 
The study will be considered successful if the superiority of at least 1 Dysport group relative 
to placebo could be demonstrated with regard to the primary efficacy endpoint.  
The primary efficacy endpoint is the change from baseline to Week 6 in the vaginal dilator 
induced pain as reported on an 11-point NRS (using the DMTS reported at baseline). 
An ANCOVA will be performed. The model will include the treatment group (2 Dysport 
doses and placebo) as factor, baseline pain and stratification variable (pain onset subtype 
(primary and secondary PVD)) as covariates. Subjects who are unable to reach the baseline 
maximum tested size at a postbaseline visit will have an imputed pain score of 10 at the 
maximum tested size for that visit. 
The primary efficacy results will be presented adjusted for covariates. The following 
estimates will be provided:  
• 
For each of the 3 treatment groups, the least squares means of change from baseline in 
vaginal dilator and 2-sided 95% confidence interval are presented. 
• 
For each of the 2 Dysport groups, the least squares means of the difference against 
placebo with a 2-sided simultaneous 80% confidence intervals will be presented. 
Non-parametrics tests may also be carried out to evaluate robustness of the results. 
Secondary efficacy endpoints will be analysed using an ANCOVA or a logistic regression 
according to the endpoints scale (categorical or continuous). The treatment group will be 
included as factor and the baseline and stratification variable as covariates in the model. 
Additional psychometric analyses will be conducted on the study data (Stage 1 and Stage 2) 
to validate the PROs used in the study. 
The scoring of patient reported questionnaires will be detailed in the SAP. For mVPAQ, the 
analysis of life interference subscale will be done with and without the item ‘ability to fall 
asleep’. The analysis of pain severity subscale will be done with and without the items 
‘unpleasantness’ and ‘distress’. The total mVPAQ will also be computed with and without 
these items. 
11.4.4 
Adjustment for Country/Centre Effect 
Descriptive analysis will be carried out to evaluate/describe any possible centre effect. 
11.4.5 
Handling of Withdrawals, Discontinuations or Missing Data  
As described in Section 11.2, for Stage 1 and Stage 2, subjects who discontinue prior to 
Week 6 for reasons unrelated to safety may be replaced at the discretion of the investigator 
and sponsor. 
Sensitivity analyses will be carried out to evaluate the impact of missing data where 
appropriate. 
11.4.6 
Data Analyses Timepoints 
11.4.6.1  Data Review Committee (End of Stage 1 - Cycle 1-Week 6) 
When all subjects in PVD2 cohorts in Stage 1 have reached Cycle 1-Week 6 visit, the DRC 
will review the unblinded efficacy and safety data to enable the selection of doses. 
Once all subjects in PVD1 cohorts have reached Cycle 1-Week 6 visit, the DRC will meet and 
based on unblinded review of all safety and efficacy data from the cohort, will recommend if 
further PVD1 cohort(s) are required or if PVD1 subjects should be removed from Stage 2.

A primary unblinded analyses will be performed. The cut-off date will be when all Stage 2 
subjects have completed the Cycle 1-Week 12 visit. Analyses will be performed on:  
• 
Subjects in Stage 1 – all safety and efficacy data available at the time of the data cut-off 
date. 
• 
Subjects in Stage 2 – all safety and efficacy data available up to Cycle 1-Week 12 visit. 
11.4.7 
Safety Evaluation 
All safety data will be included in the subject data listings. Analyses and summary tables will 
be based upon the safety population. 
All AEs will be coded according to the current version of MedDRA at the time of database 
lock and will be classified by MedDRA preferred term and system organ class. AE listings 
will be presented by subject, system organ class and preferred term. 
Incidence of all reported TEAEs and SAEs will be tabulated by treatment, group, dose and 
overall. In addition, summary tables will be presented by maximum intensity, drug 
relationship and TEAEs associated with premature withdrawal of study medication. 
A TEAE is defined as any AE that occurs during the active phase of the study if:  
• 
it was not present prior to receiving the first dose of IMP, or  
• 
it was present prior to receiving the first dose of IMP but the intensity increased during 
the active phase of the study. 
All TEAEs will be flagged in the AEs listings. 
Summary statistics (mean, median, SD and range as appropriate) by treatment group, dose 
and by overall will be presented for clinical laboratory tests at each assessment with change 
from Baseline. For laboratory data, abnormal values will be flagged in the data listings and a 
list of clinically significant abnormal values will be presented. Shift tables will be presented 
of the number and percentage of subjects with low, normal or high values and normal or 
abnormal exams. 
The number and percentage of subjects with the presence of BTX-A antibodies (neutralising) 
at Baseline will be presented. The number of seroconverters (subjects who have negative 
results at Baseline and have at least one positive result at any one post-treatment timepoint) 
for neutralising antibodies will be reported. 
11.5 
Subgroup Analyses 
Descriptive statistics for the primary efficacy endpoint and main baseline characteristics will 
be provided by pain onset subtype (primary and secondary PVD) for Stage 2 on the mITT 
population. In addition, overall adverse events summary as well as TEAEs and SAEs will be 
provided (by SOC and PT) by pain onset subtype. 
Other subgroup analyses may be planned according to clinical interest and detailed in the 
SAP. 
11.6 
Intermediate Analyses 
At the point when the DRC recommends moving to Stage 2 of the study, an intermediate 
unblinded analysis of data available from all double-blind periods of all cohorts in Stage 1 
will be performed when all subjects from the latest cohorts have completed their Cycle 1-
Week 12 visit (data cut-off date corresponding to the last Cycle 1-Week 12 visit date).

Authorised personnel from external CAs and sponsor authorised Quality Assurance personnel 
may carry out inspections and audits. The purpose of an audit is to ensure that ethical, 
regulatory and quality requirements are fulfilled in all studies performed by the sponsor. 
Auditors and inspectors must have direct access to study documents and site facilities as 
specified in Section 13.4, and to any other locations used for the purpose of the study in 
question (e.g. laboratories). 
In the event of the site being notified directly of a regulatory inspection, the investigator must

Protocol Amendments and Protocol Deviations   
13.1.1 
Protocol Amendments 
No changes from the final approved (signed) protocol will be initiated without the prior 
written approval or favourable opinion of a written amendment by the IEC/IRB, except when 
necessary to eliminate immediate safety concerns to the subjects or when the change involves 
only logistics or administration. The principal investigator and the sponsor will sign the 
protocol amendment. 
13.1.2 
Protocol Deviations and Exceptions 
All protocol deviations will be identified and recorded by the sponsor or sponsor’s 
representative. 
A protocol deviation is any change, divergence, or departure from the study design or 
procedures defined in the protocol. 
Major protocol deviations are a subset of protocol deviations that might significantly affect 
the completeness, accuracy, and/or reliability of the study data or that might significantly 
affect a subject’s rights, safety, or well-being. (For example, major protocol deviations might 
include enrolling subjects in violation of key eligibility criteria designed to ensure a specific 
subject population or failing to collect data necessary to interpret primary endpoints, as this 
may compromise the scientific value of the trial.) 
Generally, a protocol deviation qualifies as major if: 
(1) 
The deviation has harmed or posed a significant or substantive risk of harm to the 
research subject 
(2) 
The deviation compromises the scientific integrity of the data collected for the study 
(3) 
The deviation is a wilful or knowing breach of human subject protection regulations, 
policies, or procedures on the part of the investigator(s) 
(4) 
The deviation involves a serious or continuing noncompliance with any applicable 
human subject protection regulations, policies, or procedures 
(5) 
The deviation is inconsistent with Ipsen’s research, medical, and ethical principles. 
See also Section 11.1.2 for details on the impact of major protocol deviations on the inclusion 
of subjects in each analysis population. 
A minor protocol deviation is any change in the study design, study conduct and/or 
procedures that are not in accordance with the protocol and any study materials originally 
approved by the IEC/IRB but do not have a major impact on the subject’s rights, safety or 
wellbeing, or the completeness, accuracy and reliability of the study data. 
As a matter of policy, the sponsor will not grant exceptions to protocol specific entry criteria 
to allow subjects to enter a study. If under extraordinary circumstances such action is 
considered ethically, medically, and scientifically justified for a particular subject, prior 
approval from the sponsor and the responsible IRB/IEC, in accordance with the Standard 
Operating Procedure (SOP), is required before the subject will be allowed to enter the study. 
If study site personnel learn that a subject who did not meet protocol eligibility criteria was 
entered in a study (a protocol deviation), they must immediately inform the sponsor. Such 
subjects will be discontinued from the study, except in an exceptional instance following 
review and written approval by the sponsor, and if applicable according to the local regulatory 
requirement, the responsible IRB/IEC.

13.2 
Information to Study Personnel 
To ensure accurate, complete and reliable data, the sponsor or its representatives will provide 
instructional material to the study sites, as appropriate. A study initiation visit will be 
conducted prior to screening start to instruct the investigators and study coordinators. This 
session will give instruction on the protocol, the completion of the CRF and all study 
procedures. The investigator is responsible for giving information about the study to all staff 
members involved in the study or in any element of subject management, both before starting 
any study procedures and during the course of the study (e.g. when new staff become 
involved). The investigator must assure that all study staff members are qualified by 
education, experience, and training to perform their specific responsibilities. These study staff 
members must be listed on the study site authorisation form, which includes a clear 
description of each staff member’s responsibilities. This list must be updated throughout the 
study, as necessary. 
The study monitor is responsible for explaining the protocol to all study staff, including the 
investigator, and for ensuring their compliance with the protocol. Additional information will 
be made available during the study when new staff become involved in the study and as 
otherwise agreed upon with either the investigator or the study monitor. 
13.3 
Study Monitoring 
The investigator is responsible for the validity of all data collected at the site. 
The sponsor is responsible for monitoring these data to verify that the rights and wellbeing of 
subjects are protected, that study data are accurate (complete and verifiable to source data) 
and that the study is conducted in compliance with the protocol, GCP and regulatory 
requirements. 
Sponsor assigned monitors will conduct regular site visits. The investigator will allow direct 
access to all relevant files (for all subjects) and clinical study supplies (dispensing and storage 
areas) for the purpose of verifying entries made in the eCRF, and assist with the monitor’s 
activities, if requested. Adequate time and space for monitoring visits should be made 
available by the investigator. 
The site must complete the eCRFs on an ongoing basis to allow regular review by the study 
monitor, both remotely by the internet and during site visits.  
Whenever a subject name is revealed on a document required by the sponsor (e.g. laboratory 
print outs) the name must be blacked out permanently by the site personnel, and annotated 
with the subject number as identification. 
13.3.1 
Data Review Committee 
The DRC will be composed of sponsor representatives independent from the study team, 
including at least a representative from neurology therapeutic area department and a 
statistician, a non-sponsor physician expert in the treatment of vulvodynia and a CRO 
representative to assist in the logistics of the meetings. A DRC charter will be developed to 
define roles and responsibilities and the DRC meetings will take place as defined in the 
charter describing the operation of this committee.  
The Chair of the DRC will be responsible for communicating the committee’s 
recommendations to the study team who will immediately inform the investigators. 
The DRC charter will be available in the TMF. 
Refer to Section 3.1.1.2 for details of safety assessments to be done by the DRC.

13.4 
Investigator’s Regulatory Obligations 
All clinical work under this protocol will be conducted according to GCP rules. This includes 
that the study may be audited at any time by a quality assurance personnel designated by the 
sponsor, or by regulatory bodies. The investigator must adhere to the GCP principles in 
addition to any applicable local regulations. 
If requested, the investigator will provide the sponsor, applicable regulatory agencies, and 
applicable IEC/IRB with direct access to any original source documents. 
The investigator(s) should demonstrate due diligence in recruitment and screening of potential 
study subjects. The enrolment rate should be sufficient to complete the study as agreed with 
the sponsor. The sponsor should be notified of any projected delays, which may impact the 
completion of the study. 
13.5 
Audit and Inspection 
Authorised personnel from external CAs and the sponsor’s authorised Quality Assurance 
personnel may carry out inspections and audits (see Section 12). 
13.6 
Data Quality Assurance 
Monitored eCRFs shared between the investigational site and the assigned Data Management 
CRO, will be reviewed (data review) for completeness, consistency, legibility and protocol 
compliance. 
Reasons should be given on the relevant eCRF for any missing data and other protocol 
deviations. Any electronic queries and items not adequately explained will require additional 
electronic manual queries to be raised to the investigator by the monitor for 
clarification/correction. The investigator must ensure that queries are dealt with promptly. All 
data changes and clarifications can be viewed in the audit trail function of the eCRF.

ETHICS 
14.1 
Compliance with Good Clinical Practice and Ethical Considerations 
This study will be conducted in compliance with IECs/IRBs, informed consent regulations, 
the Declaration of Helsinki, ICH GCP Guidelines (Section 1), FDA 21 CFR Part 11, 
Electronic Records, Electronic Signatures, and FDA, Guidance for Industry: Computerized 
Systems Used in Clinical Trials. 
In addition, this study will adhere to all local regulatory requirements.  
Before initiating a study, the investigator/institution should have written and dated 
approval/favourable opinion from the IEC/IRB for the study protocol/amendment(s), written 
informed consent form, any consent form updates, subject emergency study contact cards, 
subject recruitment procedures (e.g. advertisements), any written information to be provided 
to subjects and a statement from the IEC/IRB that they comply with GCP requirements. The 
IEC/IRB approval must identify the protocol version as well as the documents reviewed. 
After IEC/IRB approval, changes will require a formal amendment. Once the study has 
started, amendments should be made only in exceptional circumstances. Changes that do not 
affect subject safety or data integrity are classified as administrative changes and generally do 
not require ethical approval. If ethically relevant aspects are concerned, the IEC/IRB must be 
informed and, if necessary, approval sought prior to implementation. Ethical approval on 
administrative changes will be obtained if required by local/site IEC/IRB. 
14.2 
Informed Consent for Participation in the Study 
Prior to study entry, the investigator, or a person designated by the investigator, will explain 
the nature, purpose, benefits and risks of participation in the study to each subject, subject’s 
legally acceptable representative or impartial witness. Written informed consent must be 
obtained prior to the subject entering the study (before initiation of any study-related 
procedure and administration of the IMP). Sufficient time will be allowed to discuss any 
questions raised by the subject. 
The sponsor will provide a sample informed consent form. The final version controlled form 
must be agreed to by the sponsor, and the IEC/IRB and must contain all elements included in 
the sample form, in language readily understood by the subject. Each subject’s original 
consent form, personally signed and dated by the subject or by the subject’s legally acceptable 
representative, and by the person who conducted the informed consent discussion, will be 
retained by the investigator. The investigator will supply subjects with a copy of their signed 
informed consent. 
The consent form may need to be revised during the study should important new information 
become available that may be relevant to the safety of the subject or as a result of protocol 
amendments. In this instance approval should always be given by the IEC/IRB. It is the 
investigator’s responsibility to ensure that all subjects subsequently entered into the study and 
those currently in the study sign the amended form. This is documented in the same way as 
previously described. Subjects who have completed the study should be informed of any new 
information that may impact on their welfare/wellbeing. 
The investigator should, with the consent of the subject, inform the subject’s primary 
physician about their participation in the clinical study.

14.3 
Health Authorities and Independent Ethics Committees/Institutional Review 
Boards 
As required by local regulations, the sponsor’s Regulatory Affairs group will ensure all legal 
regulatory aspects are covered, and obtain approval of the appropriate regulatory bodies, prior 
to study initiation in regions where an approval is required. 
The following documents should be submitted to the relevant IEC/IRB for review and 
approval to conduct the study (this list may not be exhaustive): 
• 
Protocol/amendment(s) approved by the sponsor, 
• 
Currently applicable IB or package labelling, 
• 
Relevant investigator’s curriculum vitae, 
• 
Subject information and informed consent document(s) and form(s), 
• 
Subject emergency study contact cards, 
• 
Recruitment procedures/materials (advertisements), if any. 
The IEC(s)/IRB(s) will review all submission documents as required, and a written favourable 
opinion for the conduct of the study should be made available to the investigator before 
initiating the study. This document must be dated and clearly identify the version number(s) 
and date(s) of the documents submitted/reviewed and should include a statement from the 
IEC/IRB that they comply with GCP requirements. 
The study may begin at the investigative site(s) only after receiving this dated and signed 
documentation of the IEC/IRB approval or favourable opinion. 
During the study, any update to the following documents will be sent to the IEC/IRB either 
for information, or for review and approval, depending on how substantial the modifications 
are: (1) IB; (2) all protocol amendments and revised informed consent(s), if any. 
At the end of the study, the EC will be notified about the study completion. 
14.4 
Confidentiality Regarding Study Subjects 
The investigator must assure that the privacy of the subjects, including their personal identity 
and all personal medical information, will be maintained at all times. In eCRFs and other 
documents or image material submitted to the sponsor, subjects will be identified not by their 
names, but by their year of birth and an identification code (identification number). 
Personal medical information may be reviewed for the purpose of verifying data recorded on 
the eCRF. This review may be conducted by the study monitor, properly authorised persons 
on behalf of the sponsor, the quality assurance unit, or regulatory authorities. Personal 
medical information will always be treated as confidential.

DATA HANDLING AND RECORD KEEPING 
15.1 
Data Recording of Study Data 
In compliance with GCP, the medical records/medical notes, etc., should be clearly marked 
and permit easy identification of a subject’s participation in the specified clinical study. 
The investigator must record all data relating to protocol procedures, IMP administration, 
laboratory data, safety data and efficacy ratings on the eCRFs provided for the study. The 
investigator, by completing the signature log, may formally designate authority to complete 
eCRFs to appropriately qualified staff having certified user access to the eCRF.  
Subject completed diaries and questionnaires will be electronic. The data will be entered by the 
subject directly into a separate EDC (ePRO) secured by individual and confidential access 
codes. Data will be accessible to the clinical site and sponsor in a read only mode.  
The investigator must, as a minimum, provide an electronic signature (e-signature) to each 
case report book to attest to the accuracy and completeness of all the data. If any changes are 
made to the eCRF, after a form has been locked and electronically signed, the investigator 
will be required to perform an additional e-signature authorising agreement with any new 
information or changes to the eCRF. 
All corrections on the eCRF will be automatically tracked and a reason for change is always 
required. In the eCRF, the audit trail function will allow the changes made to be viewed on 
each item entered. 
15.2 
Data Management 
Electronic Data Capture (EDC) will be utilised for collecting subject data (except subject 
reported questionnaires and diaries entered into an ePRO). Each site is required to have a 
computer and internet connection available for site entry of clinical data. All entries in the 
eCRF will be done under the electronic signature of the person performing the action. This 
electronic signature consists of an individual and confidential username and password 
combination. It is declared to be the legally binding equivalent of the handwritten signature. 
Only sponsor authorised users will have access to the eCRF as appropriate to their study 
responsibilities. Users must have successfully undergone software application training prior to 
entering data into the eCRF. 
Data management will be conducted by a CRO, directed by the sponsor’s Biometry group. All 
data management procedures will be completed in accordance with the sponsor and the 
contracted CRO SOPs. Prior to data being received in-house at the assigned CRO, they will be 
monitored at the investigator site (for further details please see Section 13.3 Study Monitoring). 
The CRF and other data documentation removed from the investigator site(s) will be tracked by 
the CRO and the monitor. 
The sponsor will ensure that an appropriate eCRF is developed to capture the data accurately, 
and suitable queries are raised to resolve any missing or inconsistent data. The investigator 
will receive their data, from the clinical study, in an electronic format (PDF files) which will 
be an exact copy of the eCRF and ePRO, and will include the full audit trail, for archiving 
purposes and future reference. 
Any queries generated during the data management process will also be tracked by the 
contracted Biometry CRO. It is the CRO’s study monitor’s responsibility to ensure that all 
queries are resolved by the relevant parties. 
The sponsor will also ensure that SAE data collected in the eCRF are consistent with 
information provided to the sponsor’s pharmacovigilance department (and vice versa).

The coding of an AE, medical history, surgical procedures and concomitant medication terms 
will be performed by a contracted CRO, directed by the sponsor’s Biometry Group, and 
reviewed and approved by the sponsor. Concomitant medications will be coded using 
WHODRUG and AEs/medical history terms will be coded using MedDRA. 
Complete data from enrolled subjects will be reported in the eCRFs and collected in the 
sponsor’s database. 
For screen failure subjects, at least the Unique Subject Identifier, the date of informed 
consent signature and the potential AEs which occurred during the screening phase will be 
reported in the eCRFs and collected in the sponsor’s database. Rescreened subjects will sign a 
new informed consent form and a new subject identification number will be allocated. 
15.3 
Record Archiving and Retention 
Prior to the start of the study, the monitor must ensure the archiving facilities are adequate 
and archiving/retention responsibilities of the investigator have been discussed.  
Study documents should be retained until at least 2 years after the last approval of a marketing 
application in an ICH region and until there are no pending or planned marketing applications 
in an ICH region (that is at least 15 years) or at least 2 years have elapsed since the formal 
discontinuation of clinical development of the product. However, these documents should be 
retained for a longer period if required by the local applicable regulatory requirements or by 
an agreement with the sponsor. The investigator should take measures to prevent accidental or 
premature destruction of these documents. The final archiving arrangements will be confirmed 
by the monitor when closing out the site. The sponsor will inform the investigator, in writing, 
as to when these documents no longer need to be retained. 
If the principal investigator relocates or retires, or otherwise withdraws his/her responsibility 
for maintenance and retention of study documents, the sponsor must be notified (preferably in 
writing) so that adequate provision can be made for their future maintenance and retention.

sponsor and investigator responsibilities in relation to the study. Financial remuneration will 
cover the cost per included subject, based on the calculated costs of performing the study 
assessments in accordance with the protocol, and the specified terms of payment will be 
described in the contract. The contract should describe whether costs for pharmacy, laboratory 
and other protocol required services are being paid directly or indirectly. 
Financial Disclosure Statements will need to be completed, as requested by FDA 21 CFR 
Part 54. 
16.2 
Insurance, Indemnity and Compensation

REPORTING AND PUBLICATIONS OF RESULTS 
17.1 
Publication Policy 
The sponsor encourages acknowledgement of all individuals/organisations involved in the 
funding or conduct of the study, including medical writers or statisticians subject to the 
consent of each individual and entity concerned, including acknowledgement of the sponsor. 
The results of this study may be published or communicated to scientific meetings by the 
investigators involved in the study. For multicentre studies, a plan for scientific publication 
and presentation of the results may be agreed and implemented by the study investigators or a 
Steering Committee. The sponsor requires that reasonable opportunity be given to review the 
content and conclusions of any abstract, presentation, or paper before the material is 
submitted for publication or communicated. This condition also applies to any amendments 
that are subsequently requested by referees or journal editors. The sponsor will undertake to 
comment on the draft documents within the time period agreed in the contractual 
arrangements, including clinical trial agreements, governing the relationship between the 
sponsor and authors (or the author’s institution). Requested amendments will be incorporated 
by the author, provided they do not alter the scientific value of the material. 
If patentability would be adversely affected by publication, this will be delayed until (i) a 
patent application is filed for the content of the publication in accordance with applicable 
provisions of the clinical trial agreement concerned, (ii) the sponsor consents to the 
publication, or (iii) the time period as may be agreed in the contractual arrangements, 
including clinical trial agreements, governing the relationship between the sponsor and 
authors (or authors’ institution) after receipt of the proposed publication by the sponsor, 
whichever of (i), (ii) or (iii) occurs first. 
The author undertakes to reasonably consider the sponsor's request for delay to the proposed 
publication should the sponsor reasonably deem premature to publish the results obtained at 
the then stage of the study. 
17.2 
Clinical Study Report 
As indicated in Section 11.4.6, a primary analysis will be performed after all subjects in 
Stage 2 complete the Week 12 visit. An interim Clinical Study Report (CSR) may be 
prepared.  
A final CSR will be prepared where any subject has signed informed consent, regardless of 
whether the study is completed or prematurely terminated. Where appropriate an abbreviated 
report may be prepared. The CSR will be prepared according to the ICH guideline on 
structure and contents of CSRs and will comply with any applicable regulatory requirements, 
national laws in force and will be in English.

REASON(S) FOR CHANGES 
 
The protocol was updated to add more flexibility in the duration of 
the screening period, to make the screening period consistent 
between Stage 1 and Stage 2, remove the upper age limit of subjects, 
clarify the timing of assessments performed as part of 
inclusion/exclusion criteria, revise the scoring requirement of the 
mFSFI questionnaire exclusion criterion, remove the PCS exclusion 
criterion, clarify the concomitant medications exclusion criterion, 
update the rescreening criteria, specify the PGI-S secondary endpoint 
as mean change from baseline, modify the mITT population to be 
consistent with the SAP, and correct any inconsistencies. 
Additionally, in response to the FDA agency feedback:  
• 
The recall periods for some subscales/domains of patient 
reported outcomes were modified and questionnaires 
updated (mFSFI and mVPAQ) which were appended to the 
protocol 
• 
The schedule of assessments was updated with regards to the 
frequency and timing of collection of some parameters to 
align with the recommendations 
• 
Subject interviews to assess the content relevance of the 
dilator test (primary endpoint) were added.
