How long Lewy Body Disease studies take

Of 24 phase 2 interventional studies under Lewy Body Disease, half reached primary completion within 26 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 226 mo16–45 · 24 studies——
Interventional, no phase35 mo26–61 · 63 studies—34 mo26–53 · 59 studies
Observational81 mo40–171 · 45 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.
