Ultrathin DES in Complex PCI Scenarios: the ULTRA a Multicenter Study (ULTRA)

January 19, 2022 updated by: Fabrizio D'Ascenzo, Azienda Ospedaliera Città della Salute e della Scienza di Torino

Ultrathin Drug Eluting Stents for Patients With Left-main, bifurcaTion, chRonic totAl Occlusion, or In-stent Restenosis Coronary Lesion in Real Life: the ULTRA a Multicenter Study

ULTRA is a multicenter, observational, retrospective registry, enrolling consecutive patients treated with ultrathin coronary DES (coronary stent with strut thickness < 70 um) for coronary bifurcation lesions, left main disease, chronic total coronary occlusion, and in-stent restenosis regardless of their clinical presentation. Target lesion failure (TLF a composite endpoint of cardiovascular death, target vessel myocardial infarction, target lesion revascularization and definite stent thrombosis) will be the primary end point, while its single components will be the secondary ones along with all-cause death, all acute myocardial infarction (excluding peri-procedural AMI), target vessel revascularization and BARC major bleedings (BARC 3-5). Due to the retrospective, observational nature of the registry, no formal sample size estimation is required. Patients complying with detailed inclusion criteria and with a minimum follow up of 6 months will be enrolled.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of target lesion failure (TLF)
Time Frame: Up to 2 years
A composite endpoint of cardiovascular death, target vessel myocardial infarction, target lesion revascularization and definite stent thrombosis
Up to 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of all-cause death
Time Frame: Up to 2 years
death from any cause
Up to 2 years
Incidence of acute myocardial infarction (AMI)
Time Frame: Up to 2 years
all acute myocardial infarction excluding peri-procedural myocardial infarction
Up to 2 years
Incidence of target vessel revascularization (TVR)
Time Frame: Up to 2 years
All revascularization in a vessel treated with ultrathin DES within the index procedure
Up to 2 years
Incidence of major bleedings
Time Frame: Up to 2 years
Major bleedings defined according to Bleeding Academic Research Consortium (BARC 3-5)
Up to 2 years
Incidence of cardiovascular death
Time Frame: Up to 2 years
Death from cardiovascular causes
Up to 2 years
Incidence of target Vessel Myocardial Infarction
Time Frame: Up to 2 years
Myocardial infarction whose culprit artery is unequivocally identified as an artery treated with ultrathin Drug eluting stent within the index procedure
Up to 2 years
Incidence of target lesion revascularization
Time Frame: Up to 2 years
coronary revascularization due to acute coronary syndrome or stable ischemic presentation due to a lesion previously treated with ultrathin drug eluting stent within the index procedure
Up to 2 years
Incidence of definite stent thrombosis
Time Frame: Up to 2 years
stent thrombosis in a coronary segment previously treated with ultrathin drug eluting stent
Up to 2 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2019

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
