First-In-Human Intracoronary OCT-FLIm In Patients Undergoing PCI

November 29, 2023 updated by: Jin Won Kim, Korea University Guro Hospital

First-In-Human Intracoronary Dual-modal Optical Coherence Tomography and Fluorescence Lifetime Imaging (OCT-FLIM) In Patients Undergoing Percutaneous Coronary Intervention

Patients will undergo intracoronary imaging using combined optical coherence tomography-fluorescence lifetime imaging (OCT-FLIm) during percutaneous coronary intervention, and the obtained imaging data will be used to assess the efficacy of this dual-modal catheter imaging strategy in characterizing high-risk plaque.

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.

Detailed Description

Fluorescence lifetime imaging (FLIm) is a novel imaging approach allowing label-free biochemical characterization of atherosclerotic plaque. A combined optical coherence tomography (OCT) and FLIm that can provide a simultaneous structural and biochemical assessment of atheroma has been constructed successfully. This study sought to investigate whether the dual-modal intravascular OCT-FLIm is able to characterize high-risk plaques in patients undergoing percutaneous coronary intervention.

Forty patients with multivessel coronary artery disease, who had at least one obstructive lesion (>70% diameter stenosis) that is considered suitable for PCI, will be included in the study. Culprit and mildly stenotic non-culprit plaques will be imaged using OCT-FLIm catheter.

Six-month follow-up assessment is systematically scheduled in all patients to assess temporal changes in FLIm signatures according to treatment strategies (medical therapy, interventional therapy etc).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

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
Fluorescence lifetime measurement of plaque inflammation in the target/culprit or non-target/non-culprit lesion (nanosecond)
Time Frame: day 1
Difference in fluorescence lifetime measurement reflecting plaque inflammation according to pre-specified plaque subtypes
day 1

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
Fluorescence lifetime measurement of healed plaque in the target/culprit or non-target/non-culprit lesion (nanosecond)
Time Frame: day 1
Difference in fluorescence lifetime measurement reflecting healed property according to pre-specified plaque subtypes
day 1

Time Frame: day 1
Difference in fluorescence lifetime measurement reflecting superficial calficiation according to pre-specified plaque subtypes
day 1

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
