Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion (OPEN-CTO)

October 14, 2021 updated by: Saint Luke's Health System

Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion (OPEN CTO)

This is an observational registry, sponsored by Saint Luke's Hospital. This study is to be conducted according to DHHS Guidelines, applicable state regulations, and local IRB policies and procedures. The overall objective is to address current gaps in knowledge regarding CTO-PCI, as a prospective, multi-center, single-arm study of 1,000 participants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

  • 1,000 participants will be enrolled into the OPEN CTO study.
  • Study coordinators will screen both men and women over the age of 18 who are admitted for an elective CTO-PCI procedure.
  • Study coordinators will be trained by the Coordinating Center at Saint Luke's Hospital of Kansas City.
  • Participants will be screened for Eligibility, and Informed Consent will be obtained.
  • Participants will also be asked to sign a Medical Records Release form, and a Billing Records Release form.
  • Detailed procedural data will be obtained by the Study Coordinator and local Principal Investigator.
  • Participants will undergo a Baseline interview.
  • These data will be entered into the electronic data capture system, Velos, which has stringent protections and quality controls.
  • Participants will have telephone follow-up interviews conducted by the centralized Follow-up Center at Saint Luke's Hospital.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

18 or older with CAD and at least one chronic total occluded vessel.

Description

Inclusion Criteria:

  • Subject is scheduled for a PCI procedure for at least one chronic total occlusion with TIMI antegrade flow of zero.
  • Subject is ≥ 18 years of age at the time of consent.

Exclusion Criteria:

  • The CTO segment is in a graft
  • Female subjects with a positive quantitative or qualitative pregnancy test, in accordance with hospital policy.
  • Non-English speaking

Cohorts and Interventions

Group / Cohort

Group / Cohort

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
Health Status
Time Frame: One year
Quantify the baseline health status effects of CTO among patients selected for CTO-PCI and quantify the changes associated with CTO-PCI using the Hybrid Approach.
One year

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.

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.
December 1, 2013

Primary Completion (Actual)

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.
September 1, 2017

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
