Onyx ONE Month DAPT Program

The Onyx ONE Month DAPT Program studied the most complex HBR patients — including those at the highest thrombotic risk — to provide data reflective of real-world clinical practice and help better inform short DAPT decisions.

Onyx One Global Trial

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

Primary Endpoint

Resolute Onyx™ DES met the primary endpoint for cardiac death, myocardial infarction, and stent thrombosis, showing non-inferiority vs. BioFreedom™* DCS at 12 months (17.1% vs. 16.9%).2

Acute Performance

  • Superior device success
  • Significantly higher crossover from BioFreedom DCS to Resolute Onyx DES
  • Significantly higher acute gain

Landmark Analysis
1–12 Months

Onyx ONE Global Trial Results
Published by The New England Journal of Medicine


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 HBR patients from the United States and Japan in a prospective, multicenter, single-arm trial
  • Pooled with similar “clear” Resolute Onyx DES patients from the Onyx ONE Global Trial
  • ~1,500 total patients included in primary endpoint analysis

“Clear” patients are defined as being event-free and DAPT-adherent for the first 30 days post-procedure.

Primary Endpoint Results

The Onyx ONE Clear analysis showed 7.0% cardiac death or myocardial infarction at one year, beating the performance goal of 9.7%.3

Performance goal derived from contemporary 1-month DAPT trials.#

Resolute Onyx DES Is safe and effective in real-world HBR patients on 1-month DAPT

Based on results from the Onyx ONE Clear Analysis, evaluating over 1,500 complex HBR patients.

DAPT duration decisions are best made on an individual basis. Premature discontinuation or interruption of prescribed antiplatelet medication could result in a higher risk of ST, MI, or death.
