Plain English Summary
Background and study aims
The study drug (OLX10010) is an investigational drug which is being developed by OliX Pharmaceuticals Inc., with the aim to help people who develop hypertrophic scars (a type of permanent scar) in the future. Hypertrophic scars are formed when a wound becomes red, raised, and itchy before it eventually heals. These scars tend to develop due to disease, surgical operations, or burns. There are an estimated 92 million patients in the US who have developed these scars, and this number is expected to continue to rise. In the UK it is reported by the British Skin Foundation that seven in ten people have visible scars or skin conditions, and of these people, 72% say that it affects their confidence. Research by ‘Changing Faces’ has also shown that 1,345,000 people (1 in 44 people) have a significant disfigurement to their face or body. There are currently no therapeutic drugs or methods that allow for the complete prevention or treatment of hypertrophic scars. Available physical treatment methods to remove scars include surgery or laser therapy, but these are often accompanied by further complications including pain and recurrence of the scar and can be costly. Similarly, treatments such as ointments or oral drugs have little to no effect in preventing or treating hypertrophic scars. The aims of this study are to determine the safety of the study drug and any side effects that might be associated with it, and how much of the study drug gets into the bloodstream and how long it takes the body to remove it.
Who can participate?
Healthy volunteers aged 18 to 60 years old (women In Groups A1 to A4 must be postmenopausal or have had a hysterectomy)
What does the study involve?
This study is conducted in two parts, Part A and B. In Part A, 32 participants are randomly allocated into eight groups (A1 to A8). In each of Groups A1 to A8, three participants receive OLX10010 and one participant receives a placebo (dummy drug). Groups A1 to A4 are injected subcutaneously (into the fatty layer of tissue under the skin) at a single injection site. Groups A5 to A8 are injected intradermally (into the dermis skin layer) and the doses are given at different dose volumes at either two or four injection sites. Each participant participates in one treatment period only and stays at the Clinical Research Unit (CRU) from Day -1 (the day before dosing) to Day 3 (48 hours after dosing). Participants return for a follow-up visit at 14±2 days after dosing. All groups are divided into two cohorts, with each cohort being dosed at least 24 hours apart. The first cohort comprises two participants, one of whom receives OLX10010 and one of whom receives placebo. The second cohort comprises two participants who both receive OLX10010. There is minimum of 2 weeks between dose increases to allow enough time for a safety review.
In Part B, 12 participants are randomly allocated into three groups (Groups B1 to B3) with each group consisting of four participants. In each group, three participants receive OLX10010 and one participant receives a placebo. Each participant is given three doses of OLX10010 or placebo at 2-week intervals (i.e., on the morning of Days 1, 15, and 29). Participants stay at the CRU from Days -1, 14, and 28 (i.e., the day before dosing) until Days 3, 17, and 31 (i.e., 48 hours after each dose). Participants return for a follow-up visit at 14±2 days after their final dose. The dose given at each occasion does not exceed the highest well-tolerated single dose in Part A. There is a minimum of 2 weeks between dose increases to allow enough time for a safety review.
What are the possible benefits and risks of participating?
Participants do not receive any health benefit (beyond that of an assessment of their medical status). The risks of participation are side effects such as injection site pain and reactions, although there may also be some discomfort from collection of blood samples and other study procedures.

Healthy subjects without significant conditions
This study will be conducted in 2 parts, Part A and B.
Part A will be a single subcutaneous dose (Groups A1 to A4) or intradermal dose (Groups A5 to A8), dummy controlled study. Overall, 32 subjects will be studied in 8 groups; 4 groups (Groups A1 to A4) of 4 subjects to assess OLX10010 administered subcutaneously and 4 groups (Groups A5 to A8) of 4 subjects to assess OLX10010 administered intradermally. In Groups A1 to A4, doses will be administered at a single injection site. In Groups A5 to A8, the doses will be administered at different dose volumes at either 2 or 4 injection sites. In each of Groups A1 to A8, 3 subjects will receive OLX10010 and 1 subject will receive placebo. Each subject will participate in 1 treatment period only and reside at the Clinical Research Unit (CRU) from Day -1 (the day before dosing) to Day 3 (48 hours postdose). Subjects will return for a Follow-up Visit at 14±2 days postdose. All groups will be divided into 2 cohorts, with each cohort being dosed at least 24 hours apart. The first cohort will comprise 2 subjects, 1 of whom will receive OLX10010 and 1 of whom will receive placebo. The second cohort will comprise 2 subjects; both subjects will receive OLX10010. All groups will therefore be only partially-blinded. There will be a minimum of 2 weeks between dose escalations to allow sufficient time for an adequate safety review.
A1: 1 mg of OLX10010 or placebo, subcutaneously
A2: 4 mg of OLX10010 or placebo, subcutaneously
A3: 10 mg of OLX10010 or placebo, subcutaneously
A4: 20 mg of OLX10010 or placebo, subcutaneously
A5: 4 mg of OLX10010 or placebo, intradermally (4 injection sites)
A6: 10 mg of OLX10010 or placebo, intradermally (4 injection sites)
A7: 10 mg of OLX10010 or placebo, intradermally (2 injection sites)
A8: 20 mg of OLX10010 or placebo, intradermally (4 injection sites)
Part B will be a multiple intradermal dose, dummy controlled study. Overall, 12 subjects will be studied as 3 groups (Groups B1 to B3) with each group consisting of 4 subjects. In each group, 3 subjects will receive OLX10010 and 1 subject will receive placebo. Each subject will be given 3 dose administrations of OLX10010 or placebo at 2 week intervals (i.e., on the morning of Days 1, 15, and 29). Subjects will reside at the CRU from Days -1, 14, and 28 (ie, the day before dosing, respectively) until Days 3, 17, and 31 (ie, 48 hours postdose of each dose, respectively). Subjects will return for a Follow-up Visit at 14±2 days after their final dose. The dose administered at each dosing occasion will not exceed the highest well-tolerated single dose in Part A. There will be a minimum of 2 weeks between dose escalations to allow sufficient time for an adequate safety review.
B1: OLX10010 or placebo biweekly for 3 times, intradermally (dose will be determined after Part A)
B2: OLX10010 or placebo biweekly for 3 times, intradermally (dose will be determined after Part A)
B3: OLX10010 or placebo biweekly for 3 times, intradermally (dose will be determined after Part A)
Primary outcome measures
Safety and tolerability of single subcutaneous and intradermal doses, and multiple intradermal doses of OLX10010. Safety and tolerability are evaluated by adverse events upon checking clinical symptoms, lab values, injection site tolerability, and so on. Single dose ascending groups will be monitored at Day 14. Multiple dose ascending groups will be treated with OLX10010 or placebo 3 times on Day 1, 15, and 29, and their safety profiles are monitored up to Day 43.
Secondary outcome measures
Pharmacokinetics of OLX10010 will be evaluated. The blood samples are collected at predose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, and 48 hours postdose.
