Summary

This trial aims to determine if Clascoterone can help men with male pattern hair loss. The study will compare Clascoterone solution to a placebo in two parts. In Part 1

Who is the study for?
Men over 18 with mild to moderate male pattern baldness at the top and temple areas of the scalp, who are willing to keep their hair style and color consistent, follow study instructions, maintain their diet and supplement patterns, use birth control if applicable, and make required clinic visits.
What is being tested?
The trial is testing Clascoterone 5% solution versus a placebo. It's divided into two parts: The first part (6 months) checks for effectiveness and safety in a double-blind setup. Responders then enter Part 2 for another six months in a single-blind test for long-term effects.
What are the potential side effects?
Potential side effects aren't specified here but typically include scalp irritation where the solution is applied. Since it's being tested for safety, monitoring will include physical exams, vital signs checks, ECGs, blood tests, urine samples to catch any adverse reactions.
