How long Astrocytoma studies take

Of 82 phase 1 interventional studies under Astrocytoma, half reached primary completion within 50 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 150 mo35–78 · 82 studies—49 mo35–78 · 72 studies
Phase 1/273 mo53–185 · 25 studies——
Phase 252 mo39–100 · 51 studies—54 mo41–100 · 45 studies
Observational94 mo54–104 · 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.
