2 Trial Identification 
This clinical trial (LP0084-1369) is conducted under US IND number 118384. 
EudraCT number: 2017-000228-85 
Clinicaltrials.gov identifier: NCT03115476 
 
3 Introduction and Rationale 
3.1 Actinic Keratosis 
Actinic keratosis (AK) is a common skin condition visible as thickened, cornified, scaly 
lesions and characterised histologically by atypical epithelial proliferation (1). Actinic 
keratoses usually develop on areas that are frequently exposed to the sun (e.g. face, ears, 
scalp, neck, forearms and the back of the hands). 
In population studies performed in the European Union (EU) and the United States (US), 
reported prevalence rates for AK have been approximately 11-25% of the population, while 
estimates are higher in Australian studies (up to 60%) (2). Patients with AK tend to have 
Fitzpatrick type I or II skin that burns with sun exposure and does not tan or tans minimally 
(3). 
There is increasing evidence that AK represents squamous cell carcinoma (SCC) in situ in its 
earliest stages (1, 4, 5). Histological evidence shows that contiguous AK is present in 97% of 
SCC lesions on sun-damaged skin (4). AK is linked epidemiologically to development of SCC 
(6), and both conditions share specific gene expression (7). If left untreated, AK may progress 
to SCC resulting in increased morbidity (4). 
AK usually occurs on large, sun-damaged areas of the skin (field cancerisation). Field 
cancerisation is characterised by the epithelial surface being more susceptible to the 
development of AKs or malignancies than normal skin due to DNA mutations generated in 
epidermis as a result of excessive sun exposure. This is evidenced by the presence of multiple 
subclinical and clinically visible AKs as well as multifocal pre-neoplastic changes with 
genetic mutations (8). Once field cancerisation has developed, new AKs will continue to 
develop. Most treatment therapies are directed against discrete, visible AKs, and there is an 
unmet need for improved therapies for field treatment that will reduce the rate of recurrence 
of AKs.

3.2 Experience with Investigational Medicinal Product 
Ingenol disoxate gel is a novel ingenol derivative being developed for field treatment of AKs 
on treatment areas of up to 250 cm2 (40 in2) on the face, chest and scalp. 
 
The clinical development program for ingenol disoxate gel in AK comprises phase 1, 
seamless phase 1/2 and phase 2 dose (regimen) finding trials, and phase 3 trials. The phase 1 
program addresses various issues potentially relevant to human safety including local 
tolerability, systemic safety and contact sensitization potential. One phase 1 trial investigating 
the biological effects by means of histopathology is ongoing. The phase 2 dose finding 
program is completed. The ongoing phase 3 program includes two confirmatory trials on face 
and chest, and two confirmatory trials on scalp investigating a 3-day treatment period with an 
8-week follow up and an extended 12 month follow-up period. 
 
The safety profile of ingenol disoxate gel is characterised by local skin responses (LSR): 
erythema, flaking/scaling, swelling, crusting, vesiculation/pustulation, and erosion/ulceration. 
In clinical trials, scores are assessed for each of these LSRs (on a scale from 0-4) and 
combined to a composite LSR score (on a scale from 0-24). The LSR profile observed in the 
ingenol disoxate development programme is consistent across anatomical locations. Typically, 
the LSRs peak shortly after last drug application, rapidly decline and resolve within 2 weeks. 
Adverse events (AEs) are predominantly application site reactions in the form of pain, 
pruritus and discomfort of mild or moderate intensity. 
 
In 3 phase 1/2 dose finding trials (LP0084-1013, -1014, and -1015), ingenol disoxate gel, 
0.018%, 0.037% and 0.1% were identified as effective and tolerable doses for once daily 
treatment for 2 consecutive days of AKs on face/chest, scalp, and trunk/extremities, 
respectively. With the intent of developing a dosing regimen with a better efficacy/tolerability 
ratio, these doses were further investigated in an open-label safety trial, Trial LP0084-1148. In 
this trial, dosing regimens of once daily for 3 consecutive days of ingenol disoxate gel 
0.018%, 0.037%, and 0.1% for face/chest, scalp, and trunk/extremities were evaluated and 
were all shown to be well tolerated. 
 
Based on the phase 2 trial results, ingenol disoxate gel, 0.018% once daily for 3 consecutive 
days is being investigated for treatment of the face/chest (Trials LP0084-1193 and -1194), and 
ingenol disoxate gel, 0.037% once daily for 3 consecutive days is being investigated for 
treatment of the scalp (Trials LP0084-1195 and -1196). These 4 phase 3 trials are divided into 
an 8-week short-term part (providing confirmatory efficacy data and short term safety data) 
and a 12 months extended follow up period providing data on recurrence and safety from 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 10 of 52 
 
Week 8 to Month 14. The present trial is an extension of the 4 ongoing phase 3 trials 
following the subjects for SCC and other neoplasia for additional 24 months. 
 
The safety and preliminary efficacy of ingenol disoxate gel is presented in the Investigator’s 
Brochure. 
 
3.3 Trial Rationale 
One of the main reasons for treating AK is the wish to abate the risk of progression of AK to 
SCC. This risk is in the order of 1 per 1000 AKs per year, which is in itself a small risk, but 
since patients can have dozens of AKs and the disease is chronic the cumulative risk for a 
patient can be substantial. Although it is generally assumed that removal of AKs by surgery or 
topical treatment will reduce the risk of progression, this has never been demonstrated in 
clinical trials. There may be several reasons for this lack of clinical trial evidence of a 
preventive effect of AK treatment on SCC risk: in general, the study of cancer development 
requires large cohorts and long follow-up time; even for a relatively common cancer type as 
SCC of the skin, this is a significant obstacle. Furthermore, the treatment whose effect on 
SCC risk is to be studied, can be actively allocated in the intervention period where also other 
treatment can be prohibited, but it is difficult to keep the exposure clean in a prolonged 
follow-up period. In particular, it is difficult to prohibit other treatments than the experimental 
treatment for AK. Finally, it is difficult to recruit patients for trials dedicated to study the risk 
of SCC of the skin. The latter obstacle is overcome by the design here proposed, where the 
population is initially followed for the treatment effect on AK whereas in the prolonged 
follow-up phase the emphasis shifts to long-term effects on skin neoplasia, in particular SCC. 
 
Patients who enter trials in AK are at increased risk of developing SCC from the outset and 
SCCs will be observed, no matter how effective the treatment. The occurrence of even a few 
cases of SCC after treatment with a topical product may cast a shadow over the new product 
and a large, well-controlled trial would be needed to alleviate this kind of concern. This is 
another reason for implementing this extension protocol. 
 
In this extension protocol, LEO will study the incidence of SCCs and other skin neoplasia in 
vehicle and ingenol disoxate treated patients over a period of 2 years, so that the total follow- 
up time for each patient will be 3 years and 2 months. 
 
3.4 Ethical Considerations 
This extension protocol does not include any experimental treatments or procedures, either 
active or vehicle. Patients will be seen every 6 months by a qualified dermatologist for 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 11 of 52 
 
assessment of the treatment area specified in the main trial LP0084-1193, -1194, -1195 or - 
1196. 
 
The only restricted medication during this extension protocol is the use of ingenol mebutate 
and ingenol disoxate in and within 5 cm of treatment area, as field treatment or individual 
lesion specific treatment. If it is judged by the investigator that it is in the best interest of the 
patient to receive field treatment in and within 5 cm of treatment area, such a treatment is not 
prohibited. However, investigators will be encouraged to pursue individual lesion specific 
treatment options where clinically relevant and before employing field treatment. If topical 
treatment is indicated, ingenol mebutate and ingenol disoxate are not allowed in and within 5 
cm of the treatment area. Since subjects will not be deprived of active AK treatment options, 
there is no ethical concern related to the treatment of subjects participating in this extension 
protocol.

6 Trial Design 
6.1 Overall Trial Design 
This is an international, phase 3, multi-centre, randomised, open-label, parallel group, 24- 
month trial in subjects with AK. The subjects who qualify for this trial have previously been 
enrolled in LEO trials LP0084-1193, -1194, -1195, or -1196 (‘main trial’) in which a 
treatment area has been defined.

Page 12 of 52 
 
At Visit 1 (which ideally coincides with visit 11 [Month 14]) subjects will sign the trial- 
specific consent form in the presence of the investigator and the subject’s eligibility will be 
checked. Additional trial visits will take place at Month 6, 12, 18, and 24. 
 
At Visit 2-5 the treatment area will be assessed for any adverse events (AEs). 
 
If a biopsy is taken due to suspicion of SCC or other skin neoplasia in the treatment area (see 
section 8.4.1), it will be sent for central review by an independent adjudication committee 
(IAC) with 3 expert dermatopathologists, see section 12.1. 
 
Cryotherapy is allowed in the treatment area. Investigators are encouraged to pursue these 
treatment options where clinically relevant and before employing other treatments. Until end 
of trial, if topical treatment is indicated, ingenol mebutate and ingenol disoxate are not 
allowed in, and within 5 cm of the treatment area.

6.2 Trial Schedule 
Subjects are expected to participate for up to 24 months. 
 
Planned date of first subject first visit (FSFV): Q2 2017 
Planned date of last subject first visit (LSFV): Q4 2017 
Planned date of last subject last visit (LSLV): Q4 2019 
Estimated number of trial sites and country allocation: Approximately 80 sites in Canada, 
Germany, France, Italy, Spain, the United Kingdom, and USA. 
 
6.3 Sample Size 
No formal sample size calculation has been made. The sample size is determined by the 
number of subjects who complete Visit 11 in the confirmatory phase 3 trials (LP0084-1193, - 
1194, -1195, -1196) and are willing to enter the extension protocol. Two thirds would have 
been treated with ingenol disoxate, one third with vehicle. 
 
6.4 Randomisation 
Not applicable 
 
6.5 Blinding 
The phase 3 trials LP0084-1193, -1194, -1195, or -1196 are vehicle controlled and blinded. 
The blinding will, however, not be maintained during the 2 years of the extension protocol 
except for the blinding of the adjudication committee members, who evaluate the pathology 
slides from skin neoplasias in the treatment area.

1) Visit 1 ideally coincides with visit 11 (month 14) of the main trial and should be 
performed before or at Visit 2 of the present trial. 
2) Visit 2 is 6 months after visit 11 (month 14) of main trial and the visit window is 
relative to visit 11. 
3) Information regarding medication or treatments which may suppress the immune 
system in subjects or which may alter the course of AK or SCC. Also, any 
medications (topical or systemic) and procedures used for AEs in the treatment 
area. 
4) Within treatment area only (SAEs outside treatment area are only collected if 
deemed related to IMP in main trial or reported elsewhere in the CRF). 
5) Early termination only. 
 
 
All assessments in this trial will be made in the treatment area that was documented in the 
main trial (LP0084-1193, -1194, -1195 and -1196). The study transparency used in the main 
trial should be used to reidentify the treatment area for assessment of the treated skin on the 
face, chest, or scalp for all visits in the present trial.

8.2 Subject Eligibility 
Refer to sections 7.2 and 7.3 
 
8.3 Concomitant Medication and Procedures 
The following should be collected: 
 
Information regarding medication or treatments which may suppress the immune system in 
subjects or which may alter the course of AK or SCC will be collected. 
 
Information will be collected regarding concomitant medications (topical or systemic) and 
procedures used for AEs in the treatment area. 
 
No other information on concomitant medications or procedures will be collected. 
 
Use of concomitant treatment must be recorded in the subject’s medical record and the CRF 
(e.g. treatment/drug name, route of administration, total daily dose, indication and dates of 
start and stop). 
 
If Visit 1 does not not coincide with Visit 11 of trial LP0084-1193, -1194, -1195 and -1196 
concomitant medication and procedures for the period between the two visits must be 
recorded at Visit 1.

8.4 Adverse Events 
Only AEs in the treatment area (including keratoacanthoma [KA], SCC, or other skin 
neoplasia) will be collected. AEs must be assessed and recorded as specified in section 9. 
 
If Visit 1 does not coincide with Visit 11 of the main trial (LP0084-1193, -1194, -1195 and - 
1196) events in the treatment area for the period between the two visits must be recorded at 
Visit 2. 
 
8.4.1 Adverse EventS of Special Interest and other Skin Neoplasia 
All biopsies of KA, SCC or other skin neoplasia in the treatment area should be sent for 
central review in the IAC, Section 12.1. If there are any discrepancies between the local 
histology report and the central pathology review, there should not be any changes in the 
CRF. For the central review, the local pathology laboratory will send the relevant histology 
slides to the investigator who will forward the slides to the CRO for distribution to the 
adjudication committee. Only if the original slides cannot be sent is it acceptable to use new 
slides made from the same tissue block. 
 
A biopsy should be considered in the following clinical situation: 
 
• A new lesion in the treatment area that has bled on more than 2 occasions. 
• Any papular lesion that measures more than 0.5 cm in diameter (0.2 inches). 
• A presumed actinic keratosis that has been treated twice with cryosurgery without 
resolution. 
 
8.5 Scarring 
Presence of scarring (Yes/No) in the treatment area will be recorded at visits indicated in 
Section 8.1. If scarring is present, the investigator should record in the CRF if the scarring is 
hypotrophic, hypertrophic or keloid. If a scarring is recorded it should also be recorded as an 
AE. 
 
8.6 End of Trial 
The End of Trial Form must be completed for all enrolled subjects. This includes last 
attended scheduled visit number and primary reason for withdrawal .

9 Adverse Events 
• AEs and serious adverse events (SAEs) are defined in Appendix 3: Definitions of 
Adverse Events and serious Adverse Events. 
• Classification of AEs in terms of severity, causality and outcome are defined in 
Appendix 4: Classification of Adverse Events. 
9.1 Collection of Adverse Events 
In this extension protocol, where no treatment is being administered, all AEs and SAEs 
occurring in the area treated in the phase 3 trials (treatment area) will be routinely collected 
from completion of Visit 11 in the main trial until the subject’s last visit to the clinic. 
 
SAEs occurring outside the treatment area in the main trial, and considered not related to IMP 
in these trials, will not be systematically collected. For an overview of which AEs should be 
collected, see table below.

Related to IMP in main trials 
Referenced elsewhere in the CRF (e.g. death on end of 
trial form, hospitalisation as reason for missing visit) 
 
 
AEs must be assessed by medically qualified personnel. A qualified experienced 
dermatologist must conduct all dermatologic examinations and AE evaluation of the treatment 
area defined in the main trials (LP0084-1193, -1194, -1195, -1196). 
 
At all visits, the subject will be asked a non-leading question by the (sub)investigator about 
AEs, for example: “How have you felt since I saw you last?” No specific symptoms should be 
asked for. It is important that the (sub)investigator also observes the subject for any changes 
not reported by the subject and records these changes.

Page 20 of 52 
 
9.1.1 Local Skin Responses 
Local skin responses (LSR) matching the criteria in the LSR grading scale in the pivotal 
phase 3 trials are considered AEs in this extension protocol and should be handled and 
reported as such. 
 
9.2 Reporting of Adverse Events in the CRF 
AEs reported by the subject or observed by the (sub)investigator must be recorded on the AE 
form of the CRF and should be described in the following manner: 
 
The AE term will be in precise English medical terminology (i.e. not necessarily the exact 
words used by the subject). Whenever possible, a specific diagnosis should be stated (e.g. 
allergic contact dermatitis). 
 
The duration of the AE must be reported by the start date and stop date of the event. In 
addition, it must be recorded whether the AE started prior to start of IMP. 
 
AEs must be classified in terms of severity, causality and outcome according to the definitions 
in Appendix 4: Classification of Adverse Events. 
 
9.2.1 Actions Taken as a Consequence of an Adverse Event 
Any action taken as a result of the AE must be recorded (none, concomitant medication, 
concurrent procedure). 
 
Withdrawn due to AE: it must be recorded whether the AE leads to withdrawal from the trial. 
 
9.3 Other Events to be Reported 
Overdose, medication error, misuse and abuse will not be reported since no IMP is given in 
this trial. 
 
9.3.1 Pregnancy 
Any pregnancy occurring during the main trials (LP0084-1193, -1194, -1195 and -1196) from 
Visit 1 until Visit 7 has been reported. This extension protocol investigates subjects following 
their participation in one of the four pivotal phase 3 trials without any additional treatment, 
hence pregnancies are not to be reported in the current trial as treatment has been finalised 14 
months prior to enrollment.

Version: 2.0 
Page 21 of 52 
 
9.3.2 Aggravation of Condition 
Any clinically significant aggravation/exacerbation/worsening of any medical condition(s), 
compared to baseline, must be reported as an AE. 
 
9.3.3 Adverse Events of Special Interest 
Due to the sun-damage, the target population is prone to SCC development. Sun-damaged 
skin is also prone to development of keratoacanthoma (KA) as a response to local irritation 
and/or inflammation. To ensure that all information relevant for surveillance is collected, 
SCCs and KAs in the area treated in the pivotal phase 3 trials are considered adverse events of 
special interest (AESI). 
 
For SCCs and KAs in the area treated in the confirmatory phase 3 trials (LP0084-1193, -1194, 
-1195, -1196), the relevant information will be collected in the CRF. In addition, the local 
histology report should be faxed or emailed to Global Pharmacovigilance, once available, 
using the following fax number or email address: 
 
Fax number: +45 7226 3287 
 
Email address: drug.safety@leo-pharma.com 
 
SCCs and KAs in the treatment area (defined in the main phase 3 trials) that meet the criteria 
for being serious should be reported as SAEs (please refer to section 9.4.1 for reporting 
details). 
 
The pathology slides that have been used for the initial diagnosis of the AESI will be sent for 
central pathology review by the procedure outlined in section 8.4 
 
9.4 Additional Reporting Requirements for Serious Adverse Events 
9.4.1 Investigator Reporting Responsibilities 
When reporting SAEs, the paper SAE Form – Clinical Trials, must be used, and submitted to 
LEO within 2 4 hours of first knowledge. This report should contain an assessment of 
available information on seriousness, severity, causal relationship to the IMP, comparator or 
trial procedure, the action taken, the outcome to date, and a narrative description of the course 
of the event. 
 
The completed SAE form must be faxed or scanned and e-mailed to Global 
Pharmacovigilance, LEO using the following fax number or e-mail address: 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 22 of 52 
 
Fax number: +45 7226 3287 (for Global Pharmacovigilance) 
 
E-mail address: drug.safety@leo-pharma.com (for Global Pharmacovigilance) 
 
It may be relevant for the (sub)investigator to enclose other information with the SAE form, 
such as anonymised reports of diagnostic procedures, hospital records, autopsy reports, etc. 
 
Additionally, Global Pharmacovigilance, LEO may request further information in order to 
fully assess the SAE. The (sub)investigator must forward such information to Global 
Pharmacovigilance, LEO upon request by fax or e-mail (see contact details above). 
 
The investigator must notify the local IRB(s)/IEC(s) of SAEs as required by current 
applicable legislation for the concerned country. 
 
SAEs occurring after the completion of the clinical trial including any protocol required post- 
treatment follow-up period should not be routinely sought or collected. However, such events 
should be reported to Global Pharmacovigilance, LEO (drug.safety@leo-pharma.com) if the 
(sub)investigator becomes aware of them. 
 
9.4.2 LEO Reporting Responsibilities 
Global Pharmacovigilance, LEO is responsible for assessing whether or not an SAE is 
expected. The relevant reference document for this clinical trial is: 
 
For the IMP, the Investigator’s Brochure, LEO 43204, Field Therapy, Edition No. 5 and 
subsequent updates hereof must be used (9). 
 
Global Pharmacovigilance, LEO will notify the regulatory authorities and concerned 
investigators of SAEs according to the current applicable legislation for the concerned 
countries. 
 
The IRB(s)/IEC(s) will be notified of SAEs according to the current applicable legislation for 
the concerned countries. 
 
For all non-US countries, all SAEs which are assessed as casually related to the IMP by either 
the investigator or LEO (ICH E2A Guideline), and which are unexpected (Suspected, 
Unexpected Serious Adverse Reactions (SUSARs)), are subject to expedited reporting to 
regulatory authorities and IRB(s)/IEC(s) according to the current applicable legislation in the 
concerned countries. Investigators will be notified of these on an ongoing basis. 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017

Page 23 of 52 
 
For the US, all SAEs which are assessed as casually related to the IMP by LEO (Guidance for 
Industry and Investigators – Safety Reporting Requirements for INDs and BA/BE Studies) 
and which are unexpected (Serious and Unexpected Suspected Adverse Reactions (IND safety 
report)) are subject to expedited reporting to regulatory authorities and IRB(s)/IEC(s) 
according to the current applicable legislation in the concerned countries. Investigators will be 
notified of these on an ongoing basis. 
 
9.5 Follow-up for Final Outcome of Adverse Events 
During the trial, the investigator should follow up for final outcome on all AEs (including 
SAEs). Once a subject leaves the clinical trial, the investigator should follow up on the 
outcome of all non-serious AEs classified as of possible/probable relationship to the 
investigational product for 2 months or until the final outcome is determined, whichever 
comes first. SAEs must be followed up until a final outcome has been established, i.e. the 
follow-up may continue beyond the end of the clinical trial. 
 
10 Trial Product 
Not applicable 
 
11 Statistical Methods 
Data on skin neoplasia from the 14 months observation time in the confirmatory phase 3 trials 
LP0084-1193, -1194, -1195, and -1196 will be combined with the data from the present trial. 
 
11.1 Sample Size 
No formal sample size calculation has been made. The sample size is determined by the 
number of subjects who complete Visit 11 in the pivotal phase 3 trials (LP0084-1193, -1194, - 
1195, -1196) and are willing to enter the extension protocol. Two thirds have been treated 
with ingenol disoxate, one third with vehicle. 
 
A total of 1200 subjects were planned be enrolled in the pivotal phase 3 trials (LP0084-1193, - 
1194, -1195, and - 1196) and randomised 2:1 to the two treatment groups ingenol disoxate gel 
or vehicle gel. With 800 subjects in the ingenol disoxate treatment group and 400 subjects in 
the vehicle gel group, an adequate precision of the 3-year plus 2 months incidence rate can be 
obtained. Assuming a 3-year plus 2 months rate of 4.0%, the upper 95% confidence limit will 
on average be 5.36% for ingenol disoxate gel and 5.92% for vehicle gel, and assuming a 6.0% 
rate, the upper 95% confidence limit will on average be 7.65% for ingenol disoxate gel and 
8.33% for vehicle gel.

11.2 Trial Analysis Sets 
All subjects enrolled in the trial (i.e. subjects for whom informed consent has been obtained 
and who have been registered in a clinical trial) will be accounted for in the clinical trial 
report. 
 
All randomized subjects from the pivotal phase 3 trials (LP0084-1193, -1194, -1195, -1196) 
are included in the full analysis set (FAS) and will be analysed for incidence of SCC and other 
skin neoplasia. Exclusions from the full analysis set can be considered in special cases as 
described in ICH E9, section 5.2.1., Full Analysis Set. If it is decided to exclude a subject 
from the full analysis set, a justification addressing ICH E9 will be given. 
 
A safety analysis set will be defined by excluding subjects from the full analysis for whom no 
post-baseline safety evaluations are available. 
 
The decisions regarding inclusion/exclusion of subjects and/or subject data from the trial 
analysis sets will be documented in the statistical analysis plan update . 
 
11.3 Statistical Analysis 
11.3.1 Disposition of Subjects 
The reasons for leaving the trial will be presented for the FAS by last visit attended and by 
treatment group in the main trial. This will also be done for the enrolled and eligble subjects 
not included in the FAS. 
 
11.3.2 Demographics and other Baseline Characteristics 
Descriptive statistics of demographics and other baseline characteristics will be presented for 
all subjects, by treatment group in the main trial and by country. Presentations of age, sex, 
ethnicity and race and baseline AK count by treatment group will also be given by main trial. 
 
The demographics and other baseline characteristics will be summarised for the 4 main trials 
combined as well as the subset of those who enter the extension trial. 
 
Demographics include age, sex, race, ethnicity and skin type. Other baseline characteristics 
include anatomical location (face, chest, or scalp) of treatment area in the main trials, 
treatment area size, concurrent diagnoses (from medical history and indications for 
concomitant medication), and concomitant medication. Baseline AK characteristics will 
include baseline AK count for the treatment area, duration of disease, previous treatment of

Version: 2.0 
Page 25 of 52 
 
AKs (anywhere) and previous treatment of AKs in the treatment area as reported in the main 
trial. 
 
11.3.3 Exposure and Treatment Compliance 
11.3.4 Analysis of Primary Endpoint 
The null hypothesis is that there is no difference in time to first SCC between ingenol disoxate 
gel and vehicle gel. The hypothesis will be tested against the two-sided alternative that there 
is a difference between the two treatment groups. 
 
Primary endpoint is time to first SCC in the treatment area from Visit 2 in trials LP0084-1193, 
-1194, -1195 and -1196. 
 
Only the SCC confirmed by the IAC will be used in the primary endpoint analysis. 
 
The annual and the 3-year and 2 months cumulative incidence of first event of SCC will be 
calculated for each treatment group (active and vehicle) in main trial using methods of 
survival analysis in the presence of censoring. The cumulative incidence rates will be 
presented by treatment group for the event of first SCC as primary endpoint. A proportional 
hazards model will be fitted if the model assumptions are valid. Log-rank test comparing the 
two treatment groups will be performed. For descriptive purposes, as an additional analysis, 
the difference in cumulative incidence rates between the two arms will be estimated and 
presented together with its 95% confidence interval. A landmark analysis will additionally be 
performed in order to exclude SCC and other neoplasia reported within the first 8 weeks 
which are not assumed to be associated with the trial treatment. This corresponds to left- 
truncation of the trial period at 8 weeks, the analysis will otherwise be conducted as above. 
Patients who experience a SCC before the 8-week landmark time point are excluded from the 
landmark analysis. 
 
11.3.5 Analysis of Secondary Endpoint 
For the secondary endpoint, the null hypothesis is that there is no difference in time to first 
SCC or other skin neoplasia between ingenol disoxate gel and vehicle gel. The hypothesis will 
be tested against the two-sided alternative that there is a difference between the two treatment 
groups. 
 
Secondary endpoint is time to first SCC or other skin neoplasia in the treatment area from 
Visit 2 in trials LP0084-1193, -1194, -1195 and -1196. 

 
 
Trial ID: LP0084-1369

Page 26 of 52 
 
Only the SCC or other skin neoplasia confirmed by the IAC will be used in the secondary 
endpoint analysis. 
 
Analysis of the secondary endpoint will be performed as outlined above for the primary 
endpoint. 
 
11.3.6 Analysis of Safety 
The analysis of safety will be based on the safety analysis set. 
 
11.3.6.1 Adverse Events 
AEs will be coded during the course of the trial according to Medical Dictionary for 
Regulatory Activities (MedDRA). AEs will be presented by preferred terms and primary 
system organ class (SOC). 
 
AEs from the 24-month trial period, will be summarised and included in the subject data 
listings by its start date. All adverse events will be considered treatment-emergent and will be 
included in the tabulations described in the following. In each of the tabulations, AEs are 
defined by MedDRA preferred terms within primary SOC. 
 
An overall summary of the number (percentage) of subjects with any AEs, SAEs, premature 
discontinuations from the trial due to AEs, treatment-related AEs and severe AEs will be 
presented overall and by treatment group in main trial. 
 
The number of subjects experiencing each type of AEs will be tabulated by treatment group in 
main trial regardless of the number of times each AE is reported by each subject. The 
percentage of subjects with any AEs will be compared between treatment groups by a chi- 
square test or Fisher’s exact test (if expected cell count < 5). 
 
Severity 
The severity for each type of AE will be tabulated by treatment group in main trial. Where 
there are several recordings of severity for a given type of AE, severity will be taken as the 
most severe recording for that AE. 
 
Causal relationship 
The causal relationship to IMP for each type of AE will be tabulated by treatment group. 
Where there are several recordings of causal relationship to the IMP for a given type of AE, 
causal relationship will be taken as the most-related recording from the last report of that AE, 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 27 of 52 
 
since that is when the (sub)investigator will be in possession of most information and so best 
able to judge causal relationship. 
 
Related AEs are defined as AEs for which the (sub)investigator has not described the causal 
relationship to IMP as ‘not related’. The number of subjects experiencing each type of related 
AE will be tabulated regardless of the number of times each related AE is reported by each 
subject. The percentage of subjects with related AEs will be compared between treatment 
groups by a chi-square test or Fisher’s exact test (if expected cell count < 5). 
 
Most common adverse events 
The most common AEs (≥2% of subjects in the active treatment group in the main trial) will 
be presented by treatment group. 
 
Serious adverse events and withdrawal 
SAEs will be evaluated separately and a narrative for each will be given. AEs leading to 
withdrawal from trial will be listed. 
 
Adverse events of special interest 
AESI will be presented by treatment group in the main trial. For the AESI the number of 
events with agreement and disagreement between data from the AE form in the CRF and data 
from the central review will be presented by treatment group. A narrative for each AESI will 
be given. 
 
11.3.7 Interim Analysis 
No interim analyses are planned. 
 
11.3.8 General Principles 
All significance tests will be two-sided using the 5% significance level . All confidence 
intervals will be presented with 95% degree of confidence. 
 
An observed-cases approach will be used for tabulations of data by visit (i.e. involving only 
those subjects who attended each specific visit). 
 
Categorical data will be summarised using the number and percentage of subjects in each 
category. Continuous data will be summarised using the mean, median, standard deviation 
(SD), minimum and maximum values.

Any changes from the statistical analysis planned in this clinical trial protocol will be 
described and justified in a protocol amendment/the statistical analysis plan update and/or in 
the clinical trial report dependent on the type of deviation. 
 
11.3.9 Handling of Missing Values 
Missing values for time to occurrence of SCC or other neoplasia will be handled as censored 
observations. 
 
12 Trial Committees 
12.1 Independent Adjudication Committee 
In LEO ingenol trials, squamous cell carcinoma (SCC) and keratoacanthoma (KA) inside the 
treatment area have been defined as an AESI. KA may be difficult for some pathologists to 
distinguish from SCC and may be underreported due to the fear of misdiagnosing the 
malignant SCC. As many AK patients are prone to SCC as well as KA due to the heavy sun 
damage, it is of great importance that possible tumours that occur after treatment with ingenol 
disoxate are diagnosed correctly. An independent adjudication committee (IAC) has therefore 
been assembled to provide consistent evaluation of the incidence of KA in the patient 
population as opposed to the incidence of SCC. The IAC comprises 3 medical doctors, who 
are experts in dermatopathology. 
 
All biopsies of AESIs and other skin neoplasia in the treatment area at any time during the 
trial will be sent to the IAC for central review, as described in sections 8.4 and 9.3.3. 
 
See Appendix 4: Contact list of LEO, protocol authors, vendors, trial committees and 
coordinating investigators for contact details on all trial committee members. 
 
13 Case Report Forms and Data Handling 
13.1 Case Report Forms (CRFs) 
Data will be collected by means of Electronic Data Capture (EDC). The investigator or staff 
authorised by the investigator will enter subject data into electronic CRFs. Data recorded in 
the electronic CRFs will be accessible to the trial site and LEO personnel immediately after 
entry. The CRFs must be maintained in an up-to-date state by the trial site at all times. 
 
The investigator must verify the correctness of the data entered by the site by electronically 
date and sign all CRFs used. This signature information will be kept in the audit trail and 
cannot be altered. Any correction(s) made by the (sub)investigator or authorised site staff to 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 29 of 52 
 
the CRF after original entry will be documented in the audit trail. Changes to data already 
approved will require the re-signature by the investigator. The person making the change to 
the data, and the date, time and reason for the change will be identified in the audit trail. 
 
For archiving purposes, each investigator will be supplied with a copy of the CRFs for all 
subjects enrolled at the trial site. This is done after completion of the trial and before access to 
the eCRF is revoked. Audit trail information will be included. CRFs must be available for 
inspection by authorised representatives from LEO, from regulatory authorities and/or 
IEC/IRBs. 
 
13.2 Data Handling 
Subject data should be entered into the CRF as soon as possible after each visit in accordance 
with the requirements described in the Clinical Trial Agreement. Queries for discrepant data 
will be generated automatically by the system upon entry or manually by the monitor or the 
data manager. All queries will be raised electronically within the EDC system. This systematic 
validation will ensure that a clean and consistent database is provided for the statistical 
analysis. 
 
13.3 Source Data 
For all data recorded, the source document must be defined in a source document agreement 
or similar document at each trial site. There must only be one source defined at any time for 
any data elements. 
 
Source data should as a general rule be recorded in the subject’s medical record or other 
defined document normally used at the trial site. Source data not normally collected as a 
routine part of the clinical practice at the site may be entered on a worksheet. 
 
If the worksheet does not become part of the subject’s medical record, the following should as 
a minimum be added to the subject’s medical record: 
• Date(s) of conducting the informed consent process (date of enrolment) including 
date of provision of subject information 
• A statement from the investigator to verify that each of the eligibility criteria are 
met for each subject 
• Subject ID 
• The fact that the subject is participating in a clinical trial. 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 30 of 52 
 
• Other relevant medical information 
The trial monitor will check the CRFs for accuracy and completeness by verifying data 
recorded in the CRF against source data to ensure such records are consistent. 
13.4 Trial Monitoring 
During the course of the trial, the monitor will visit the trial site to ensure that the protocol 
and GCP are adhered to, that all issues have been recorded to perform source data 
verification, and to monitor drug accountability. 
 
The monitoring visit intervals will depend on the trial site’s recruitment rate, the compliance 
of the trial site with the protocol and GCP. 
 
In order to perform their role effectively, monitors and persons involved in quality assurance 
and inspections will need d irect access to source data, e.g. medical records, laboratory reports, 
appointment books, etc. If the electronic medical record does not have a visible audit trail, the 
investigator must provide the monitor with signed and dated printouts. In addition, relevant 
site staff should be available for discussions at monitoring visits and between monitoring 
visits (e.g. by telephone). 
 
14 Handling of an Urgent Safety Measure 
An Urgent Safety Measure is a measure taken to implement an action/protocol deviation 
under an emergency. This is defined within the EU Directive as “…the occurrence of any new 
event relating to the conduct of the trial or the development of the investigational medicinal 
product where that new event is likely to affect the safety of the subjects, the sponsor and the 
investigator shall take appropriate urgent safety measures to protect the subjects against any 
immediate hazard.” (Article 10(b) of Directive 2001/20/EC). 
 
If the investigator becomes aware of information that necessitates an immediate change in the 
clinical trial procedure or a temporary halt to the clinical trial in order to protect clinical trial 
subjects from any immediate hazard to their health and safety, the investigator can do so 
without prior approval from LEO, regulatory authority(ies) or IRB(s)/IEC(s). 
 
The investigator must immediately inform LEO - by contacting the CPM or medical expert - 
of this change in the clinical trial procedure or of the temporary halt providing full details of 
the information and the decision making process leading to the implementation of the urgent 
safety measure.

Version: 2.0 
Page 31 of 52 
 
LEO must act immediately upon receipt of the urgent safety measure notification in 
accordance with the internal procedures and national requirements. 
 
15 Quality Assurance/Audit 
The clinical trial will be subject to audits conducted by LEO or inspections from domestic or 
foreign regulatory authorities or from IRBs/IECs. Audits and inspections may take place 
during or after the trial. The investigator and the site staff as well as LEO staff have an 
obligation to cooperate and assist in audits and inspections. This includes giving auditors and 
inspectors direct access to all source documents and other documents at the trial site relevant 
to the clinical trial. This includes permission to examine, verify and reproduce any records 
and reports that are important to the evaluation of the trial. 
 
If the trial site is contacted for an inspection by competent authorities, LEO must be notified 
immediately. 
 
16 Completion of Trial 
16.1 Trial Completion Procedures 
End of trial is defined as the date of the last subject’s last visit in each participating country 
and overall (all countries). 
 
Investigators will be informed when subject recruitment is to cease (if applicable) 
 
16.1.1 Criteria for Premature Termination of the Trial and/or Trial Site 
LEO, the investigator, the IRB/IECs or competent authorities may decide to stop the trial, part 
of the trial or a trial site at any time, but agreement on procedures to be followed must be 
obtained. 
 
If a trial is suspended or prematurely terminated, the investigator must inform the subjects 
promptly and ensure appropriate therapy and follow-up. As specified by applicable regulatory 
requirements, the investigator or LEO must promptly inform IRB/IECs and provide a detailed 
written explanation. Relevant competent authorities must be informed. 
 
The trial must be terminated if the perception of the benefit/risk ratio (judged from clinical 
signs and symptoms, (S)AEs and/or remarkable safety laboratory changes) becomes 
unfavourable for the continuation of the trial. 
 
Due to the design of this trial, there are no statistical criteria for trial termination.

16.2 Provision for Subject Care Following Trial Completion 
In order to ensure appropriate treatment of the subjects after they have completed the trial, the 
subjects will be treated at the investigator’s discretion or referred to other physician(s) 
according to standard practice. 
 
16.3 Archiving of Trial Documents 
The investigator at each trial site must make arrangements to store the essential trial 
documents including the Investigator Trial File (ICH E6, Guideline for Good Clinical 
Practice) until LEO informs the investigator that the documents are no longer to be retained or 
longer if required by local regulations. 
 
In addition, the investigator is responsible for the archiving of all relevant source documents 
so that the trial data can be compared against source data after the completion of the trial (e.g. 
in case of an inspection from regulatory authorities). 
 
The investigator is required to ensure the continued storage of the documents even if the 
investigator leaves the clinic/practice or retires before the end of the required storage period. 
 
The destruction process must ensure confidentiality of data and must be done in accordance 
with local regulatory requirements. 
 
17 Ethics and Regulatory Authorities 
17.1 Institutional Review Boards (IRBs)/Independent Ethics Committees 
(IECs) and Regulatory Authorities 
Written approval or favourable opinion must be obtained from relevant IRB/IECs prior to the 
enrolment of subjects. 
 
Any amendments to the approved clinical trial must be approved by/receive favourable 
opinion from relevant IRBs/IECs and regulatory authorities as required prior to the 
implementation. 
 
The appropriate regulatory authority(ies) must be notified of/approve the clinical trial as 
required.

17.2 Ethical Conduct of the Trial 
This clinical trial must be conducted in accordance with the principles of the revision current 
at the start of the trial of the World Medical Association (WMA), Declaration of Helsinki, 
Ethical Principles for Medical Research Involving Human Subjects. 
 
17.3 Subject Information and Informed Consent 
All subjects shall receive written and verbal information concerning the clinical trial. This 
information will emphasise that participation in the clinical trial is voluntary and that the 
subject may withdraw from the clinical trial at any time and for any reason. All subjects will 
be given an opportunity to ask questions and will be given sufficient time to consider before 
consenting. 
 
The subject’s signed and dated informed consent to participate in the clinical trial must be 
obtained prior to any clinical trial related procedure being carried out in accordance with ICH 
GCP (4.8) and all applicable laws and regulations. 
 
17.4 Processing of Personal Data 
This protocol specifies the personal data on trial subjects (e.g. age, gender, health condition, 
height, medical history, test results, etc.) which shall be collected as part of the trial and 
processed during and after trial completion. 
 
Personal data collected as part of the clinical trial will be transferred to/from the 
institution/investigator and LEO. 
 
Processing of personal data on behalf of LEO requires a written agreement between LEO and 
the relevant party which covers collection, processing and transfer of personal data in the 
clinical trial. In certain cases an agreement on transfer of personal data may also be required. 
 
Investigators and LEO must ensure that collection, processing and transfer of personal data 
are in compliance with national legislation on data protection and privacy. 
 
The investigator/institution may be considered as data controller when they wish to use 
personal data collected in the clinical trial for their own purpose such as publication of 
clinical trial results. 
 
Subjects [(or their legally acceptable representative)] must be asked to consent to the 
collection, processing and transfer of their personal data to [EU and non-EU countries] for the 
purpose of conducting the clinical trial, research and development of new or existing

to enter the extension protocol. 
Main criteria for 
inclusion 
1. Signed and dated informed consent has been obtained. 
2. The subject has been treated in one of the trials LP0084-1193, - 
1194, -1195, or -1196 and has been evaluated at Visit 11 of that 
trial. 
Main criteria for 
exclusion 
1. The subject is in need of treatment with ingenol mebutate or 
ingenol disoxate in the selected treatment area* . 
2. The subject is enrolled in any other interventional clinical trial.

incidence of first event of SCC will be calculated for each treatment 
group (active and vehicle) using methods of survival analysis in the 
presence of censoring. The incidence rates will be presented for the 
event of first SCC as primary endpoint . A proportion hazards model will 
be fitted if the model assumptions are valid. Log-rank test comparing the 
two arms will be performed. For descriptive purposes, as an additional 
analysis, the difference in cumulative incidence rates between the two

arms will be estimated and presented together with its 95% confidence 
interval. A landmark analysis will additionally be performed in order to 
exclude SCC and other neoplasia reported within the first 8 weeks which 
are not assumed to be associated with the study treatment. This 
corresponds to left-truncation of the trial period at 8 weeks, which is 
otherwise conducted as above. Patients who experience a neoplasia 
before the 8-week landmark time point are excluded from the landmark 
analysis.

Appendix 2: Definitions of Adverse Events and Serious Adverse Events 
Adverse Event Definition 
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 
subject administered a pharmaceutical product and which does not necessarily have a causal 
relationship with this treatment. An AE can therefore be any unfavourable and unintended 
sign (including an abnormal laboratory finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational) product, whether or not related to the medicinal 
(investigational) product. (ICH Harmonized Tripartite Guideline for Good Clinical Practice, 
E6 (R1)). 
 
This definition includes: 
 
• accidental injuries, events related to trial procedures, reasons for any unfavourable 
and unplanned change in medication (drug and/or dose), clinically significant 
worsening of pre-existing conditions, or reasons for admission to hospital or 
surgical procedures unless these were planned before enrolment. It also includes 
AEs commonly observed and AEs anticipated based on the pharmacological effect 
of the IMP. In addition, any laboratory abnormality assessed as clinically 
significant by the (sub)investigator must be recorded as an AE. 
Serious Adverse Event Definition 
 
An SAE is any untoward medical occurrence that 
 
• results in death 
• is life-threatening 
• requires inpatient hospitalisation or prolongation of existing hospitalisation. 
Planned hospitalisation or planned prolonged hospitalisation do not fulfill the 
criteria for being an SAE but should be documented in the subject’s medical 
record. 
• results in persistent or significant disability/incapacity 
• is a congenital anomaly/birth defect 
or 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 43 of 52 
 
• is a medically important condition. Events that may not be immediately life- 
threatening or result in death or hospitalisation but may jeopardise the subject or 
may require intervention to prevent one of the other outcomes listed in the 
definition above. Examples are intensive treatment in an emergency room or at 
home for allergic broncospasm, blood dyscrasias and convulsions that do not result 
in hospitalization, development of drug dependency or drug abuse.

Page 44 of 52 
 
Appendix 3: Classification of Adverse Events 
Severity 
The severity of the AE should be described in terms of mild, moderate or severe according to 
the (sub)investigator’s clinical judgement. 
 
Mild 
An AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual 
activities of daily living. 
Moderate 
An AE that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, causing 
discomfort but poses no significant or permanent risk of harm to the subject. 
Severe 
An AE that interrupts usual activities of daily living, or significantly affects 
clinical status, or may require intensive therapeutic intervention. 
If the severity of an AE worsens, a new AE should be recorded. 
 
Causality 
 
The causal relation of the AE to the use of the IMP should be described in terms of probable, 
possible or not related according to the following: 
 
Probably 
related 
Follows a reasonable temporal sequence from administration of the IMP. 
Could not be reasonably explained by the subject’s clinical state, 
environmental or toxic factors or other therapies administered to the subject. 
Follows a known pattern of response to the IMP. 
Disappears or decreases on cessation or reduction in dose of the IMP. 
Reappears or worsens upon re-challenge. 
Possibly 
related 
Follows a reasonable temporal sequence from the administration of the IMP. 
Could also be reasonably explained by the subject’s clinical state, 
environmental or toxic factors or other therapies administered to the subject. 
Follows a known pattern of response to the IMP. 
Not related 
Does not follow a reasonable temporal sequence from administration of the 
IMP. 

 
 
Trial ID: LP0084-1369 
Date: 25-Jul-2017 
Version: 2.0 
Page 45 of 52 
 
 
Is better explained by other factors like the subject’s clinical state, 
environmental or toxic factors or other therapies administered to the subject. 
Does not reappear or worsen upon re-challenge. 
Does not follow a known pattern of response to the IMP. 
 
 
Outcome 
 
The outcome of the event should be classified and handled as follows: 
 
Recovered/ 
resolved 
The event has stopped. The stop date of the event must be recorded. 
Recovering/ 
resolving 
The subject is clearly recovering from an event. The event is not yet 
completely resolved. 
Not 
recovered/ 
not resolved 
Event is still ongoing. 
Recovered/re 
solved with 
sequelae 
The event has reached a state where no further changes are expected and the 
residual symptoms are assumed to persist. An example is hemiparesis after 
stroke. 
The stop date of the event must be recorded. In case of a SAE, the sequelae 
should be specified. 
Fatal 
The subject has died as a consequence of the event. Date of death is recorded 
as stop date for the AE. 
Unknown 
Unknown to (sub)investigator, e.g. subject lost to follow-up.

of Directive 2001/20/EC of the European Parliament and the Council of the European Union. 
 
Overall rationale for the amendment 
The reason for the amendment is to change the definition of the FAS to include all 
randomised subjects from the pivotal phase 3 trials. The amendment also addresses requests 
for changes from the Health Authorities in Europe and US after their review of the protocol.

The sample size is determined by the 
number of subjects who complete Visit 11 
in the confirmatory phase 3 trials (LP0084- 
1193, -1194, -1195, -1196) and are willing 
to enter the extension protocol and is 
 expected to be around 1080.

area for the period between the two visits 
must be recorded at Visit 28.4.1 
8.4.1 Adverse Events of Special Interest 
and other Skin Neoplasia 
• A new lesion in the treatment area that 
has bled on more than 2 occasions. 
• Any papular lesion that measures more 
than 0.5 cm in diameter (0.2 inches). 
• A presumed actinic keratosis that has 
been treated twice with cryosurgery 
without resolution.

of Adverse 
Events 
SAEs occurring outside the treatment 
area in the main trial, and considered 
not related to IMP in these trials, will 
not be systematically collected. For an 
overview of which AEs should be 
collected, see table below.

Clarification 
11.1 Sample 
size 
 The total number of subjects in the trials is 
 around 1200, and assuming 10% drop outs 
 after 14 months, the number of subjects 
 being offered the extension protocol will 
 be around 1080. 
A total of 1200 subjects were planned be 
enrolled in the pivotal phase 3 trials 
(LP0084-1193, -1194, -1195, and - 1196) 
and randomised 2:1 to the two 
treatment groups ingenol disoxate gel or 
vehicle gel. With 800 subjects in the 
ingenol disoxate treatment group and 
400 subjects in the vehicle gel group, an 
adequate precision of the 3-year plus 2 
months incidence rate can be obtained. 
Assuming a 3-year plus 2 months rate of 
4.0%, the upper 95% confidence limit 
will on average be 5.36% for ingenol 
disoxate gel and 5.92% for vehicle gel, 
and assuming a 6.0% rate, the upper 
95% confidence limit will on average be 
7.65% for ingenol disoxate gel and 
8.33% for vehicle gel.

11.2 Trial 
Analysis Sets 
All enrolled and eligble randomized 
subjects from the pivotal phase 3 trials 
(LP0084-1193, -1194, -1195, -1196) are 
included in the full analysis set (FAS) and 
will be analysed for incidence of SCC and 
other skin neoplasia. 
Change definition of FAS 
Analysis of 
Primary 
Endpoint 
The null hypothesis is that there is no 
difference in time to first SCC between 
ingenol disoxate gel and vehicle gel. The 
hypothesis will be tested against the two- 
sided alternative that there is a 
difference between the two treatment 
groups. 
The annual and the 3-year and 2 months 
cumulative incidence of first event of SCC 
will be calculated for each treatment group 
(active and vehicle) in main trial using 
methods of survival analysis in the 
presence of censoring. 
Specification of the null 
hypothesis for the primary 
endpoint 
Analysis of 
Secondary 
Endpoint 
For the secondary endpoint, the null 
hypothesis is that there is no difference 
in time to first SCC or other skin 
neoplasia between ingenol disoxate gel 
and vehicle gel. The hypothesis will be 
tested against the two-sided alternative 
that there is a difference between the 
two treatment groups. 
Specification of the null 
hypothesis for the secondary 
endpoint

Urgent Safety 
Measure 
LEO must act immediately upon receipt of 
the urgent safety measure notification in 
accordance with the internal procedures 
and national requirements.
