How long Cancer Pain studies take

Of 15 phase 3 interventional studies under Cancer Pain, half reached primary completion within 34 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 334 mo28–51 · 15 studies——
Interventional, no phase18 mo10–40 · 75 studies—17 mo10–40 · 72 studies
Observational24 mo16–40 · 25 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.
