About this trial
Androgenetic alopecia is a common form of hair loss that can affect quality of life. This randomized controlled trial aims to evaluate the efficacy and safety of topical 2-Deoxy-D-ribose (2dDR) hydrogel compared with topical minoxidil 5% solution in the treatment of mild to moderate androgenetic alopecia in adults aged 18 to 50 years. Sixty participants will be randomized into 2 treatment groups. The 2dDR group will apply 1 gram of topical 2dDR hydrogel once daily to the affected scalp areas for 6 months. The minoxidil group will apply topical minoxidil 5% solution to the affected scalp areas for 6 months according to sex-specific dosing in the protocol.
Participants will undergo clinical assessment, trichoscopic evaluation, and standardized scalp photography at baseline, Week 12, and Week 24. The study will also assess tissue vascular endothelial growth factor (VEGF) levels using scalp biopsy specimens obtained at baseline and after 3 months of treatment in both groups. Safety will be evaluated through adverse event monitoring and clinical scalp examination during follow-up visits.

Treatments tested in this trial
Topical 2-Deoxy-D-ribose Hydrogel
DrugTopical 2-Deoxy-D-ribose hydrogel prepared with sodium alginate. The hydrogel will be composed of sodium alginate, propylene glycol, 2-phenoxyethanol, and 2-Deoxy-D-ribose in water. Participants will apply 1 gram once daily to targeted scalp areas for 6 months.
Topical Minoxidil 5% Solution
DrugTopical minoxidil 5% solution administered to targeted scalp areas for 6 months. Male participants will apply 1 cc twice daily, and female participants will apply 1 cc once daily.
Treatment groups
Trial outcomes
Primary outcomes
Change in Terminal Hair Density
Change in terminal hair density in the predefined trichoscopic assessment areas after 12 weeks of treatment, compared between the topical 2-Deoxy-D-ribose hydrogel group and the topical minoxidil 5% solution group.
Change in Total Hair Density
Change in total hair density in the predefined trichoscopic assessment areas after 12 weeks of treatment, compared between the topical 2-Deoxy-D-ribose hydrogel group and the topical minoxidil 5% solution group.
Change in Tissue VEGF Level
Change in tissue vascular endothelial growth factor (VEGF) levels from baseline to Week 12, measured using scalp biopsy specimens in both treatment groups.
Secondary outcomes
Change in Terminal Hair Density at Week 24
Change in terminal hair density in the predefined trichoscopic assessment areas after 24 weeks of treatment, compared between the topical 2-Deoxy-D-ribose hydrogel group and the topical minoxidil 5% solution group.
Change in Total Hair Density at Week 24
Change in total hair density in the predefined trichoscopic assessment areas after 24 weeks of treatment, compared between the topical 2-Deoxy-D-ribose hydrogel group and the topical minoxidil 5% solution group.
Global Photographic Assessment
Change in standardized scalp photographs assessed independently by 3 blinded dermatologists using a 7-point modified physician global assessment scale ranging from -3 (significant disease progression) to 3 (excellent improvement).
Patient Global Assessment
Participant-reported overall improvement using a 5-point scale: 0 = no improvement, 1 = mild response (less than 25%), 2 = moderate response (25% to 49%), 3 = good response (50% to 74%), and 4 = very good response (75% or more).
