LEADERS FREE - NEJM October 2015

Leaders Free a prospective, double-blind, randomized (1:1) clinical trial comparing the BioFreedom™ DCS to the GazelleTM BMS in High Bleeding Risk (HBR) patients with 1 month DAPT.

Leaders Free is currently the only published trial of complex patients and lesions to exclusively enroll HBR patients mandating a 1 month DAPT for all.


BioFreedom is the only active stent with 1 month DAPT that has demonstrated superior outcomes to BMS11

With Leaders Free, BioFreedom becomes the standard of care for High Bleeding Risk (HBR) patients11

  • Leaders Free is the first randomized clinical trial dedicated to HBR patients
  • Such patients are often excluded from stent and drug trials, constitute a rapidly growing proportion of PCI candidates and suffer high event rates.
  • Together with a one-month only DAPT course, the use of a BA9-DCS was both significantly safer and more effective than a control BMS in HBR patients

Even greater safety and efficacy than the general LF population

The pre-specified Acute Coronary Syndrome sub-group of the Leaders Free trial was presented as a late breaking clinical trial at Euro PCR 2016 by Dr Christophe Naber.

This sub-group analysis reinforces the benefit of the BioFreedom DCS vs BMS in HBR patients. The improvement in safety and efficacy achieved with BioFreedom is even greater in the high risk HBR ACS patient population.


In HBR patients with an ACS, BioFreedom combined with 1-month DAPT displays significantly better efficacy and safety, with significantly lower cardiac mortality and myocardial infarction than a BMS.

LEADERS FREE 2 years: Safety and Efficacy preserved

High Bleeding Risk patients: safety and efficacy benefits of BioFreedom™ Drug-Coated Stent over BMS are preserved up to two years

BioFreedom™ is the only active stent with CE mark for ultra-short 1 month DAPT in High Bleeding Risk (HBR) patients, supported by clinical data from a double-blind randomized controlled trial.

LEADERS FREE 2 year follow-up maintains that BioFreedom and 1 month DAPT followed by SAPT alone should be the treatment strategy of choice for HBR patients undergoing PCI.
