This study tests the safety and how well a new drug, called **VDPHL01**, works for men with *Androgenetic Alopecia* (AGA), also known as male pattern baldness. AGA is when a hormone makes hair fall out. The drug **VDPHL01** is a pill not yet approved for general use. The study will last about 13 months and requires 11 visits to the study center. The first seven visits are during the placebo-controlled period, where some men get the real drug and some get a fake one (placebo). In the last four visits, everyone gets the real drug. To join, you must be a man aged 18-65 with mild to moderate AGA, be healthy, and keep your hair the same length and style. You should not have certain heart or thyroid issues, recent hair treatments, or be taking certain medications.

• The study lasts 13 months with 11 visits.
• All participants will eventually receive the actual drug.
• You must maintain the same hair length and style.
