How long Fibromyalgia studies take

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

Start to primary completionEvery sponsorIndustryNon-industry
Phase 220 mo13–35 · 24 studies——
Phase 320 mo15–26 · 17 studies——
Interventional, no phase15 mo6–31 · 449 studies—16 mo6–31 · 436 studies
Observational27 mo8–91 · 88 studies—25 mo8–109 · 81 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.
