About this study

The DR vs DK trial is designed to elucidate the benefits of Double Rewire crush technique (DR-Crush) over Double Kissing Crush (DK-Crush) technique in patients with Unprotected Left Main Bifurcation lesions (ULMb).

Read the detailed description

DR vs DK is a multicentre, randomized, prospective, non-inferiority clinical trial designed to evaluate the efficacy and safety of DR crush over DK crush for patients with ULMb. More than 12 tertiary centres from Spain will participate including patients. Subjects with Medina 1,1,1 ULMb will be randomized in a 1:1 fashion to DR or DK crush. In order to avoid bias, the Sirolimus coronary stent will be used in all patients (UltimasterTM TanseiTM). The use of Intracoronary imaging techniques are recommended. The primary endpoint is target lesion failure (TLF) including target vessel myocardial infarction, cardiac death and TLR. Other endpoints address individual event of primary end-point, and target vessel revascularization. The safety objective is the ST. Recruitment began in January 2022 and will be completed in January 2024; 180 patients will be randomized.

What is being measured

The primary outcome is the main question the study is designed to answer.

    Measured: 12 months

  2. Rate of stent thrombosis

    The safety endpoint was stent thrombosis (ST), according to the definition by Academic Research Consortium.

    Measured: 12 months

Secondary outcomes (2)

  1. Rate of MACE

    as the composite of cardiac death, non-fatal target vessel myocardial infarction (TVMI), and unplaned target vessel revascularization

    Measured: 1 month

  2. Rate of MACE

    as the composite of cardiac death, non-fatal target vessel myocardial infarction (TVMI), and unplaned target vessel revascularization

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing DK crush and DR crush in people with Coronary Artery Disease, run by Fundación EPIC.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 18 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of target vessel failure (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05258318, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2025.
