The EVOPACS trial was recently published in the JACC

EVOPACS was an investigator-initiated, double-blind trial comparing Evolocumab vs Placebo treatment in the management of LDL levels, on the background of a high-intensity statin treatment of 40mg atorvastatin. The primary endpoint was calculated LDL-C reduction (%) over an eight week time period. The mean difference in calculated LDL-C change was -40.7% in favour of Evolocumab compared to Placebo. 2mt Ulm provided the Webspirit Data capture system, CTU Bern was involved in Data Quality surveillance and Statistical analyses.

The primary endpoint analyses of the BIOSTEMI trial were recently published in the Lancet

It used a Bayesian analysis to combine data from a previous trial (BIOSCIENCE, STEMI subgroup) with the data newly acquired. Two stents were compared, an ultra-thin strut drug eluting stent vs a thin strut drug eluting stent, randomisation and data acquisition were done in the Webspirit system (2mt Ulm). CTU Bern was involved in planning of the trial, data quality checks and statistical analyses. For further reading and the commentary, see Lancet: paper comment
