Resolute Onyx DES Now CE 
Marked for 1-month DAPT in HBR

Advancing DAPT Evidence

High bleeding risk (HBR) patients are a large, growing, complex population that historically had little evidence to support treatment decisions. For these reasons, Medtronic initiated the Onyx ONE Month DAPT Program.

Onyx ONE Month DAPT Program Enrolled a Highly Complex HBR Patient Population

Table illustrating details of patients enrolled in the Onyx ONE Month DAPT Program


Onyx ONE Global Study

First prospective, randomised, 1-month DAPT trial comparing a DES to a DES in ~2,000 HBR patients.

Primary Endpoint

Met with Resolute Onyx DES (17.1%) noninferior to BioFreedom DCS (16.9%) for cardiac death (CD), myocardial infarction (MI), and stent thrombosis (ST)

Acute Performance 

  • Superior device success§
  • Significantly higher crossover from BioFreedom DCS to Resolute Onyx DES||

Landmark Analysis
1–12 Months
after DAPT Discontinuation¶2

Low event rates shown for Resolute Onyx DES in a highly complex HBR patient population, including significantly lower MI versus BioFreedom DCS.#

Onyx ONE Clear Study

The first study in the United States and Japan evaluating 1-month DAPT duration in HBR patients with a current DES.

Onyx ONE Clear Analysis

  • 752 US/Japan HBR patients from prospective, multicenter, single-arm trial
  • Pooled with similar “clear” Resolute Onyx DES patients from the Onyx ONE Global Study
  • ~1,500 patients included in primary endpoint analysis

Primary Endpoint Results

The Onyx ONE Clear study showed 7.0% cardiac death or myocardial infarction at one year, beating the performance goal of 9.7%.1
