How long Meningitis studies take

Of 19 phase 3 interventional studies under Meningitis, half reached primary completion within 15 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry

Phase 315 mo7–28 · 19 studies——
Interventional, no phase28 mo10–34 · 24 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.
