Scalp — ANR-001.1
Scalp combination study — target-area hair count and width, Day 0–120
Objective
Evaluate the effect of the minoxidil + latanoprost combination on target-area hair count and hair shaft width relative to the individual components.
Population
Adults with androgenetic alopecia
Formulation
Topical minoxidil + latanoprost fixed-dose combination; individual components evaluated as comparators
Duration
120 days, once-daily application
Comparator
Combination vs latanoprost alone vs minoxidil alone
Sample size
Early-phase cohort (see limitations)
Design
Early-phase evaluation; results expressed as a relative index normalized to the combination arm (= 100)
Endpoints
- Change in target-area hair count, Day 0–120
- Change in average hair shaft width, Day 0–120
- Combination
- Latanoprost
- Minoxidil
Early-phase evaluation; results expressed as a relative index normalized to the combination arm (= 100). Duration: 120 days, once-daily application.
Observed findings
The combination showed a directionally larger relative change in hair count and hair width than either component alone — consistent with the dual-mechanism hypothesis.
Limitations
Early-phase data from a small cohort; results are expressed as a relative index rather than absolute changes; the findings require confirmation in larger, randomized, controlled trials.
Next development step
A larger randomized controlled study to define effect size, optimal concentration, vehicle, tolerability and safety.
