abstract = {{OBJECTIVE} To assess factors associated with regulatory approval or reasons for failure of investigational therapeutics in phase 3 or pivotal trials and rates of publication of trial results. {DESIGN}, {SETTING}, {AND} {PARTICIPANTS} Using public sources and commercial databases, we identified investigational therapeutics that entered pivotal trials between 1998 and 2008, with follow-up through 2015. Agents were classified by therapeutic area, orphan designation status, fast track designation, novelty of biological pathway, company size, and as a pharmacologic or biologic product. {MAIN} {OUTCOMES} {AND} {MEASURES} For each product, we identified reasons for failure (efficacy, safety, commercial) and assessed the rates of publication of trial results. We used multivariable logistic regression models to evaluate factors associated with regulatory approval.

{RESULTS} Among 640 novel therapeutics, 344 (54\%) failed in clinical development, 230 (36\%) were approved by the {US} Food and Drug Administration ({FDA}), and 66 (10\%) were approved in other countries but not by the {FDA}. Most products failed due to inadequate efficacy (n = 195; 57\%), while 59 (17\%) failed because of safety concerns and 74 (22\%) failed due to commercial reasons. The pivotal trial results were published in peer-reviewed journals for 138 of the 344 (40\%) failed agents. Of 74 trials for agents that failed for commercial reasons, only 6 (8.1\%) were published. In analyses adjusted for therapeutic area, agent type, firm size, orphan designation, fast-track status, trial year, and novelty of biological pathway, orphan-designated drugs were significantly more likely than nonorphan drugs to be approved (46\% vs 34\%; adjusted odds ratio [{aOR}], 2.3; 95\% {CI}, 1.4-3.7). Cancer drugs (27\% vs 39\%; {aOR}, 0.5; 95\% {CI}, 0.3-0.9) and agents sponsored by small and medium-size companies (28\% vs 42\%; {aOR}, 0.4; 95\% {CI}, 0.3-0.7) were significantly less likely to be approved.

{CONCLUSIONS} {AND} {RELEVANCE} Roughly half of investigational drugs entering late-stage clinical development fail during or after pivotal clinical trials, primarily because of concerns about safety, efficacy, or both. Results for the majority of studies of investigational drugs that fail are not published in peer-reviewed journals.},
