With LEADERS FREE, BioFreedom™ becomes the standard of care for High Bleeding Risk (HBR) patients

LEADERS FREE is a prospective, double-blind, randomized (1:1) clinical trial comparing the BioFreedom™ drug coated stent (DCS) to the Gazelle™ bare metal stent (BMS) in 2466 High Bleeding Risk (HBR) patients with 1 month dual anti-platelet therapy (DAPT).

The results demonstrated that BioFreedom™ is superior to a bare metal stent with respect to the primary safety and efficacy endpoints at 1 year when used with a 1-month course of DAPT11.

LEADERS FREE is currently the only published trial to exclusively enroll HBR patients with 1 month DAPT.

LEADERS FREE, at 1 year proved that BioFreedom™ is the only active stent with 1 month DAPT that demonstrated significantly superior outcomes to BMS in High Bleeding Risk Patients11. NEJM (October 2015)

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.  JACC (January 2017)

 

BioFreedom™ is now listed as stent of choice in ESC DAPT guidelines, for 1 month-ultra short DAPT in patients with stable CAD in whom longer DAPT regimes poses safety concerns12

Trial design and unique HBR patients^

Rationale and Design of the LEADERS FREE Trial
A Randomized Double-Blind Comparison of the BioFreedom Drug-Coated Stent vs the Gazelle Bare Metal Stent in Patients at High Bleeding Risk Using a Short (1 Month) Course of Dual Antiplatelet Therapy Urban p. Am Heart J. 2013 May;165(5):704-9


LEADERS FREE - 1 year follow-up: BioFreedom™ is significantly safer and more efficacious than a BMS11

  • LEADERS FREE is the first randomized clinical trial dedicated to HBR patients who received 1 month of DAPT followed by single antiplatelet therapy.
  • 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 an ultra short one-month only DAPT course, the use of BioFreedom™ (a Biolimus A9™ polymer and carrier free DCS) was both significantly safer and more effective than a control BMS in HBR patients.

LEADERS FREE - Pre-specified ACS subgroup - Even greater safety and efficacy than the general LF population13

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 Christoph K. Naber and published13.

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 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 maintained at two years14.

LEADERS FREE: Two-Year Outcomes of High Bleeding Risk Patients after Polymer-Free Drug-Coated stents14

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 II - Safety and Efficacy in a North American population

Reproducibility of LEADERS FREE findings
> Safety of DCS with 30 day DAPT in HBR patients15
> Effectiveness of DCS with 30 day DAPT in HBR patients15
