How long Alopecia Areata studies take

Of 30 phase 2 interventional studies under Alopecia Areata, half reached primary completion within 24 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 224 mo15–35 · 30 studies——
Phase 332 mo18–46 · 20 studies——
Interventional, no phase13 mo9–24 · 21 studies——

Each figure is the month by which half the studies had reached primary completion, with the range in which the middle half did. Studies still running count until their last registry update; studies that stopped early are left out. Phase 1 includes early phase 1; observational means prospective or not stated, as retrospective and cross-sectional studies date a window of data rather than a study.
