How long Gastroparesis studies take

Of 20 phase 2 interventional studies under Gastroparesis, half reached primary completion within 24 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 224 mo11–31 · 20 studies——
Interventional, no phase28 mo11–58 · 65 studies—35 mo15–59 · 56 studies
Observational81 mo20–142 · 47 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.
