1 Introduction
Trial LP0084-1013 was a seamless phase 1/2 clinical trial constituting 2 parts: a phase 1 open
label, dose escalation part and a phase 2 randomised double-blind, vehicle-controlled part.
The trial is reported in two interdependent clinical study reports each presenting one part of
the trial. This report describes the results of Part 1 of the trial, identifying the maximum
tolerated dose (MTD) with a focus on safety and tolerability of LEO 43204 gel and cream
formulations and undertaken in a dose escalation manner. The cream formulation was
discontinued after cohort 4 (0.012%) due to CMC development issues which did not affect the
quality of the investigational medicinal product in this trial and therefore have no
consequences for the analysis and interpretation of the collected data.
All tables and figures in Part 1 are presented in-text (gel) or end-of-text (cream) in this CSR
Part 1 document.
The LP0084-1013 main clinical study report contains the introduction, information on ethics,
objectives, trial administrative structure, investigational plan, and statistical methods for the
whole of the trial. Also, the results from Part 2 of the trial (dose selection) are reported here
and finally, the trial in full is evaluated in the discussion.
The clinical study report synopsis exists as a separately approved document and includes both
Part 1 and Part 2 results.
The schedule of all trial procedures for all trial visits for Part 1 is presented in Table 1.

2 Trial Objectives and Response Criteria/Endpoints – Part 1
2.1 Primary Objectives
To identify MTD levels of LEO 43204 gel and cream, respectively, after once daily
treatment for 2 consecutive days
Dose escalation beyond cohort 4 continued with gel formulation only due to CMC
development issues with the cream formulation, which did not affect the quality of the
investigational medicinal product in this trial and therefore have no consequences for the
analysis and interpretation of the collected data. Consequently, the MTD of LEO 43204 cream
could not be identified (see Section 5.8 of the LP0084-1013 main clinical study report).
2.2 Secondary Objectives
To evaluate safety of LEO 43204 gel and cream, respectively, after once daily treatment
for 2 consecutive days
Dose escalation beyond cohort 4 continued with gel formulation only (see Section 2.1 and
LP0084-1013 main clinical study report, Section 5.8).
2.3 Primary Response Criterion
Dose limiting toxicity based on LSRs up to and including Day 8
2.4 Other Evaluations
2.4.1 Evaluation of (Serious) Adverse Events
Incidence of AEs and SAEs
Incidence of AEs and LSRs leading to discontinuation of the trial medication
Incidence and severity of LSRs
Any adverse drug reactions (ADRs) reported
Changes in vital signs, ECGs, and blood laboratory parameters that are out of normal
range and clinically relevant
Reason for withdrawal
2.4.2 Evaluation of Laboratory Data
Abnormal haematology and biochemistry laboratory values
2.4.3 Evaluation of Other Observations
Change from baseline to Week 2 in ECG assessments
LP0084-1013 20-Aug-2015 Page 12 of 54
The ECG evaluation is erroneously defined in the clinical study protocol and was updated to
reflect the actual ECG assessments (see Section 5.8 of the LP0084-1013 main clinical study
report).

3 Trial Population – Part 1
3.1 Overview
This report describes the results from Part 1 of the trial. Part 2 results are described in
LP0084-1013 main clinical study report.
3.2 Disposition of Subjects
A total of 86 subjects were enrolled in the trial, 6 were screening failures, 2 were excluded as
recruitment goals for all cohorts were met, 1 was a voluntary withdrawal, and thus 77 subjects
were included in Part 1. All 77 subjects completed all visits. In the group administered
LEO 43204 in gel formulation 3 subjects were included in the 0.0015% cohort, 3 subjects in
the 0.003% cohort, 6 in the 0.006% cohort, 6 in the 0.012% cohort, 17 in the 0.018% cohort,
and 18 in the 0.025% cohort. Out of the group administered LEO 43204 in cream formulation
3 subjects were included in the 0.0015% cohort, 3 subjects in the 0.003% cohort, 6 in the
0.006% cohort, and 12 in the 0.012% cohort. A listing of discontinued subjects can be found
in Appendix 2.1 (Part 1), Listings 1-1 and 1-2.
The first subject was enrolled on 09-Oct-2013 and the last subject´s last visit was on
03-Jul-2014. The last subject had scheduled last visit 23-May-2014 and the visit 03-Jul-2014
was a follow-up visit.
The individual visit dates are listed in Appendix 2.4 (Part 1), Listing 4-4 (Part 1).
3.3 Protocol Deviations
A listing of the protocol deviations during the trial conduct is in Appendix 2.2 (Part 1), Listing
2-1. All comments made in the comment field in the CRF are in Appendix 2.2 (Part 1), Listing
2 2. The log of protocol deviations was also reviewed to ascertain protocol deviations.
One subject (Subject Number ) had a major protocol deviation: the subject did not
receive the second dose of investigational product due to AE.
All other protocol deviations were considered minor and are not discussed further in the text.
3.4 Trial Analysis Set
The ‘evaluable subjects analysis set’ was defined as all subjects who received at least one
application of trial medication and had LSRs recorded at all visits up to and including Day 8,
or had experienced a DLT at one or more visits up to and including Day 8. The safety analysis
PPI
LP0084-1013 20-Aug-2015 Page 14 of 54
set was defined as all subjects who received at least one application of trial medication and
had safety information available post treatment.
Of the 86 enrolled subjects 77 subjects were included in the trial of whom all were included in
the evaluable subjects analysis set and safety analysis set.
Listings of the trial analysis sets and reasons for exclusion from the trial analysis sets (screen
failures) are in Appendix 2.3 (Part 1), Listings 3-1 and 3-2, respectively.
3.5 Demographics and Other Baseline Characteristics
Results are presented for the LEO 43204 gel formulation cohorts with cream formulation
results for cohort 1 to 4 as end-of-text for information.
The median age at baseline was 69.0 years for all cohorts in total for both gel (Table 2) and
cream treatment groups (Table 12). All subjects in both treatment groups were white and most
subjects were men, non-Hispanic or Latino with Fitzpatrick skin type II (Table 3 and Table
13). The median duration of AK was 6.0 years for the group treated with gel and 5.0 years in
the group treated with cream (Table 4 and Table 14). Most subjects in both treatment groups
had a history of AK treatment and the most common AK treatment was cryo/liquid nitrogen
and 5-fluorouracil (Table 5 and Table 15). About half of the subjects in both treatment groups
had a history of skin disease. The most common skin disease history was seborrhoeic
keratosis for the gel treatment group and photodermatitis for the cream treatment group (Table
6 and Table 16). Median number of AKs at baseline was 10.0 for the group treated with gel
and 12.0 for the group treated with cream (Table 7, Table 17, and Appendix 2.6 [Part 1]).
There were some differences between cohorts, as would be expected with groups of such
small sizes, but these are not expected to influence the interpretation of the results with regard
to MTD.
Listings of demographic and baseline data are in Appendix 2.4 (Part 1).

4 Exposure and Treatment Compliance– Part 1
All 77 subjects received first administration of medication and 71 subjects received the
second administration (>90%). Out of the 6 subjects not applying the second dose 4 subjects
were in the gel formulation cohorts (3 in the 0.025% cohort and 1 in the 0.018% cohort) and 2
subjects were in the cream formulation cohorts (both in the 0.012% cohort).
A listing is provided in Appendix 2.5 (Part 1), Listing 5-1.

5 Safety Evaluation – Part 1
Note that the primary response criterion for Part 1 was dose-limiting toxicity (DLT) up to and
including Day 8, and that this information is presented in Section 5.3.1.
Results are presented for the LEO 43204 gel formulation cohorts with cream formulation
results for cohort 1 to 4 as end-of-text for information.
5.1 Adverse Events
5.1.1 Brief Summary of Adverse Events
An overview summary of AEs is presented in Table 8 (gel) and Table 18 (cream). All cohorts
for both gel and cream had subjects with AEs and most AEs were related to treatment.
Approximately half of the subjects had administration site reactions (MedDRA high level
group term) and relatively few AEs were of severe intensity (Table 10 and Table 21). There
were no deaths, 2 subjects had SAEs (squamous cell carcinoma (SCC) of skin inside
treatment area and breast cancer, both had gel treatment), and 5 subjects had discontinued
treatment due to AEs (see Section 5.2).
5.1.2 Display of Adverse Events
An overall summary of the AEs is showed in Table 8 (gel) and Table 18 (cream).

5.1.3 Analysis of Adverse Events
The most commonly reported AEs among all cohorts were within the primary SOC ‘general
disorders and administration site conditions’ and the most commonly reported AEs by SOC
and preferred term for the gel cohorts were application site pain and application site pruritus
(Table 9 and Table 19). The cream cohorts had generally few AEs with application site pain as
the most commonly reported AE among the 4 cohorts (Table 19).
Adverse events in the ‘eye disorders’ SOC were reported for 5 subjects in the gel cohorts (2 in
the 0.025% cohort, 1 in the 0.0015% cohort, 1 in the 0.012% cohort, and 1 in the 0.018%
cohort) and 2 subjects in the cream cohorts (both in the 0.012% cohort) (Table 9 and Table
19).
One subject in the 0.018% gel cohort had herpes simplex (not related to treatment) and no
subjects in Part 1 reported insomnia (Table 9, Table 19, Appendix 2.7 [Part 1], Listing 7-1).
Approximately half of the subjects had administration site reactions (MedDRA high level
group term) and most administration site reactions were of mild or moderate intensity.
Administration site reactions of severe intensity were reported for 2 subjects in the cream
cohorts and none in the gel cohorts (Table 10, gel and Table 21, cream).
Listings are available in Appendix 2.7 (Part 1), Listings 7-1, 7-2, and 7-3.

5.2 Deaths, other Serious Adverse Events, and other Significant Adverse
Events
Narratives of SAEs and other significant adverse events are provided end-of-text, Section 8.
No deaths were reported.
5.2.1 Serious Adverse Events
Two subjects had 1 SAE each: SCC of skin (inside treatment area) and breast cancer (non-
cutaneous). Both were assessed as not related to treatment and the treatment was gel for both
subjects.
Subject Number had an SAE (basal cell carcinoma) that was downgraded to AE (AK)
and is thus not reported as an SAE.
For end-of-text narratives, see Section 8.1.
5.2.2 Other Significant Adverse Events
Five subjects (3 in the gel cohorts and 2 in the cream cohorts) discontinued treatment with
investigational product due to AEs after the first application but remained in the trial
(Appendix 2.7 [Part 1], Listing 0-3). Out of these, 1 subject (Subject Number ) had
application site pain, conjunctival hyperaemia, and application site discomfort; 2 subjects
(Subject Numbers and ) had application site pain only; 1 subject (Subject Number
) had eyelid oedema, and 1 subject (Subject Number ) had application site erythema
and application site discolouration (Appendix 2.7 [Part 1], Listings 7-1 and 0-3). Note that the
AE form in the CRF for Part 1 did not contain a specific field to record that the reported AE
lead to discontinuation from treatment. All AEs leading to discontinuation from treatment are
thus based on the investigator comments in the CRF (Appendix 2.7 [Part 1], Listing 0-3). For
Subject Numbers and the AEs leading to discontinuation from treatment were not
specified in the investigator comments and each narrative thus contains all AEs reported
during Day 1 and 2.
For end-of-text narratives, see Section 8.2.
5.3 Local Skin Responses
Figure 1 (gel) and Figure 3 (cream) illustrate the tendency towards an increase in maximum
composite LSR score with increasing dose, from 7 (0.0015% cohort) to 17 (0.025% cohort)
for gel and from 6 (0.0015% cohort) to 13 (0.012% cohort) for cream. Individual LSR
measurements are in Appendix 2.7 (Part 1), Listing 7-4.

5.3.1 Dose-limiting Toxicities
The objective of Part 1 was to identify MTD levels of LEO 43204 gel and cream, after once
daily treatment for 2 consecutive days. The MTD was defined as the highest dose level with
less than 4 out of 12 subjects (cohorts 1 to 4) or less than 6 out of 18 subjects (cohorts 5 and
6) experiencing a DLT. The number of subjects in each cohort depended on the number of
observed DLTs; however, the MTD was always to be confirmed in a cohort of 12 or 18
subjects. LEO 43204 formulated as cream was originally part of the trial objectives but testing
was discontinued after cohort 4 (0.012%) due to CMC development issues with the cream
formulation, which did not affect the quality of the investigational medicinal product in this
trial and therefore have no consequences for the analysis and interpretation of the collected
data (detailed description in Section 8.3 of the clinical study protocol). Therefore, tables and
figures for the cream formulation are presented end-of-text. The dose escalation rules are
presented in Figure 2, an overview of DLTs in Table 11 (gel) and Table 20 (cream), and
individual DLT measurements in Appendix 2.7 (Part 1), Listing 7-4.
LP0084-1013 20-Aug-2015 Page 33 of 54
Figure 2 Dose Escalation Rules
Cohorts 1 to 3
LEO 43204 in gel or cream formulation was administered to subjects in cohort 1 (0.0015%) to
cohort 3 (0.006%) with no DLTs.
Cohort 4
LEO 43204, 0.012% was administered in gel or cream formulation. Two subjects receiving
the cream formulation had DLTs and no DLTs were reported for the gel formulation. Hence, 6
additional subjects were treated with LEO 43204 cream, 0.012% (according to protocol) and
1 DLT was observed. Out of the 3 subjects with DLTs 2 subjects did not get the second
administration of treatment (see Section 5.2.2 and Appendix 2.7 [Part 1], Listing 0-3). One of
LP0084-1013 20-Aug-2015 Page 34 of 54
the subjects with discontinued treatment (Subject Number ) also had LSR component
‘swelling’ of grade 4 (Appendix 2.7 [Part 1], Listing 0-4).
Sponsor’s decision to discontinue dose-escalation with the cream formulation was not based
on the results in the first 4 cohorts, but due to CMC development problems, as described in
the first paragraph of Section 5.3.1. The gel cohort was moved forward to the next dose level.
Due to high variability in LSRs in the first 4 cohorts it was decided from cohort 5 and
onwards to increase the number of subjects per cohort from 6 (with a possible extra 6) to 9
(with a possible extra 9) to reduce variability. Thus, the MTD was defined as the dose with an
occurrence of less than 6 DLTs among 18 subjects instead of less than 4 DLTs among 12
subjects.
Cohort 5
LEO 43204, 0.018% was administered in gel formulation only, due to the sponsor’s decision
to discontinue treatment with the cream formulation (see first paragraph of Section 5.3.1). No
DLTs were reported. One subject did not receive the second treatment administration, as
decided by the investigator, due to LSRs that did not meet the DLT criteria (see Appendix 2.7
[Part 1], Listing 0-4).
Cohort 6
In cohort 6 (0.025%) 2 of the first 9 subjects had DLTs and 2 subjects did not receive the
second treatment administration but did not meet the DLT criteria: 1 subject refused treatment
due to bilateral eyelid oedema and 1 subject had a application site erythema and did not
receive second dose as per investigator decision (see Section 5.2.2). As 2 subjects had DLTs
and 2 subjects did not receive the second dose it was decided to extend the cohort with 9
additional subjects to gain more confidence with the 0.025% dose before further dose
escalation. In this extended cohort, 4 more subjects had DLTs, i.e. 6 subjects in total for the 18
subjects in the cohort. In addition, 1 subject did not receive the second dose due to application
site pain, but it was decided that the subject was to remain in the trial (Appendix 2.7 [Part 1],
Listing 0-3). Thus, the dose escalation was stopped at this point in accordance with the
predefined stopping criteria and the MTD was confirmed at the 0.018% dose by extending
cohort 5 with an additional 8 subjects. According to the clinical study protocol 9 subjects were
to be included in this extended cohort, but the last subject was not included as none of the first
8 subjects had a DLT. As none of the subjects in the extended cohort 5 had DLTs the MTD
was 0.018%.
Doses to be used in Part 2
It was decided to move forward with the MTD dose (0.018%) and 2 doses below in Part 2.
PPI
LP0084-1013 20-Aug-2015 Page 35 of 54
Hence, the doses to be used in Part 2 were the following: 0.018%, 0.012%, 0.006%, and
vehicle.

5.4 Vital Signs, Physical Findings and other Observations Related to Safety
5.4.1 Vital Signs and Physical Findings
Vital sign monitoring showed no findings of concern. Listings are in Appendix 2.8 (Part 1),
Listing 8-3.
5.4.2 ECG Assessments
The ECG assessments were analysed by a central CRO and the results evaluation and
conclusion is presented in a separate ECG Safety Report. The ECG analysis assessed the
change in ECG recordings from baseline to Day 1, Day 3, and Week 2, respectively, for all
dose cohorts and formulations. A listing with individual ECG measurements is in
Appendix 2.8 (Part 1), Listing 8-4.
A small increase in QTcF was noted on Day 3 in the 3 higher dose groups receiving the gel
formulation of LEO 43204. It should be noted that group sizes were rather small and there
was no obvious relationship to the dose administered regarding this effect. Furthermore, no
evidence for an effect of LEO 43204 on QTcF was observed after application of the cream
formulation.
5.5 Clinical Laboratory Evaluation
One subject (Subject Number ) in the LEO 43204 gel, 0.018% group had severe elevated
hepatic enzymes that were non-related to medication and the event was recovered/resolved.
No other subjects had abnormal laboratory measurements of concern and thus, clinical
laboratory evaluations showed no findings of concern. Haematology and biochemistry
parameters are available in Appendix 2.8 (Part 1), Listings 8-1 and 8-2 and Appendix 2.7
(Part 1), Listing 7-1).

6 Overall Conclusions of Part 1
The trial population consisted of primarily old men with fair skin. The median duration of
AK was 5 to 6 years (gel and cream), most subjects had a history of AK treatment and the
most common AK treatments were cryo/liquid nitrogen and 5-fluorouracil (Section 3.5)
The maximum post-baseline composite LSR score had a tendency towards an increased
score with increasing dose for both gel and cream cohorts (Section 5.3)
Based on pre-defined criteria, the MTD of LEO 43204 gel formulation in the 2-day
treatment regimen was 0.018%. As per protocol, the MTD dose (0.018%) and 2 lower
dose levels (0.006% and 0.012%) were taken forward into Part 2 of the trial (Section
5.3.1)
There were no deaths; 2 subjects had 1 SAE each: SCC of skin and breast cancer; and 5
subjects discontinued treatment due to AEs (Section 5.2)
All cohorts for both gel and cream had subjects with AEs, most AEs were related to
treatment, approximately half of the subjects had administration site reactions, and
relatively few AEs were of severe intensity (Section 5.1.3)
Vital signs and laboratory monitoring showed no evidence of safety concern (Sections 5.4
and 5.5)
ECG monitoring showed no association between LEO 43204 treatment and evidence of
cardiac effects (Section 5.4.2)
