OBJECTIVES: To present a snapshot of experimental cardiovascular research with a
focus on geographical and temporal patterns of early termination due to poor
accrual. SETTING: The Aggregate Analysis of ClinicalTrials.gov (AACT) database,
reflecting ClinicalTrials.gov as of 27 March 2016. DESIGN: The AACT database was
searched for all cardiovascular clinical trials that started from January 2006 up
to December 2015. RESULTS: Thirteen thousand and seven hundred twenty-nine
cardiovascular trials were identified. Of these, 8900 (65%) were classified as
closed studies. Globally, 11% of closed trials were terminated. This proportion
varied from 9.6% to 14% for trials recruiting from Europe and Americas,
respectively, with a slightly decreasing trend (p=0.02) over the study period.
The most common reason for trials failing to complete was poor accrual (41%).
Intercontinental trials exhibited lower figures of poor accrual as the reason for
their early stopping, as compared with trials recruiting in a single continent
(28% vs 44%, p=0.002). CONCLUSIONS: Poor accrual significantly challenges the
successful completion of cardiovascular clinical trials. Findings are suggestive
of a positive effect of globalisation of cardiovascular clinical research on the
achievement of enrolment goals within a reasonable time frame.
