Brief summary
This is a randomised, double-blind, placebo-controlled, single ascending dose treatment, multi-cohort study. The study will evaluate 5 dose levels of the investigational product, OLX72021, in 5 cohorts. Dose levels will be evaluated in a sequential manner starting at the lowest dose level. Healthy male volunteers with mild to severe androgenetic alopecia (AGA), aged 18 to 75 years of age (inclusive) at the time of screening are eligible for recruitment. The total maximum study duration for participants in this study is 87 days (approx. 12 weeks). This includes a screening period (Day -28 to Day -14) and 56 days (± 3 days) post-treatment follow-up. Androgenetic alopecia has been linked to an imbalance of androgen hormones. OLX72021 is designed to target the androgen receptor (AR) gene, leading to reduced AR protein expression in the body. Because androgenetic alopecia could be caused by an imbalance of androgens, blocking the AR gene helps to reduce these harmful responses and allow hair growth to return to normal. The information learned from this study may help future participants with androgenetic alopecia.
Interventions
This is a randomised, double-blind, placebo-controlled, single ascending dose treatment, multi-cohort study. Up to 30 healthy male volunteers with mild to severe androgenetic alopecia (AGA), aged 18 to 75 years of age (inclusive) at the time of screening will be enrolled in a total of 5 cohorts (Cohorts 1 to 5). The study will evaluate 5 dose levels of the investigational product, OLX72021, at the following dose levels: • Cohort 1: 0.6 mg (0.1 mg/injection) • Cohort 2: 3.0 mg (0.5 mg/injection) • Cohort 3: 6.0 mg (1.0 mg/injection) • Cohort 4: 7.2 mg (1.2 mg/injection) • Cohort 5: 9.0 mg (1.5 mg/injection) A single OLX72021 treatment will be administered as 6 intradermal injections to the scalp on study Day 1. Each dose level will be evaluated in a cohort of 6 participants with 4 participants receiving OLX72021 and 2 participants receiving placebo. Dosing in each cohort will start with 2 sentinel participants (1 participant will receive OLX72021 and the other will receive placebo). The safety and tolerability of each sentinel participant will be monitored until Day 2 prior to dosing the remainder of participants in each cohort. The clinical facility staff will administer the study drug via intradermal injections to participants. Compliance will be monitored by site staff witnessing of dosing and documentation in participant study file. Dosing compliance will be recorded in study-specific patient diaries recording the date, time and dose administered.
