April 23, 2021 updated by: Nitiloop Ltd.

A Prospective, Single Center, Non-randomized, Single Arm, Open Label, Study to Evaluate the Safety and Effectiveness of the NovaCross™ Micro-catheter in Facilitating Crossing Chronic Total Occlusion (CTO) Coronary Lesions

This is an open label, single-center, prospective, pivotal study in which the investigational device, NovaCross™ micro-catheter, will be tested in up to 15 patients scheduled to undergo CTO-PCI using an anterograde approach.

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.

Enrollment (Actual)

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.

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.

Ages Eligible for Study

25 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

Device: NovaCross
A device that is intended to asisst interventional cardiologists during catheterization to cross and open coronary chronic total occlusions

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
Cardiovascular Adverse Events (Primary Safety)
Time Frame: 30 days
Accumulative incidence of Major Adverse Cardiovascular Events (MACE), defined as the composite of death, myocardial infarction (MI), or urgent revascularization (target vessel revascularization (TVR) or urgent coronary artery bypass surgery (CABG)).
30 days
Technical Success (Primary Efficacy)
Time Frame: 1 day
Intra-procedural technical success, defined as the ability of the NovaCross™ microcatheter to successfully facilitate placement of a guidewire beyond a native coronary chronic total occlusion in the true vessel lumen
1 day

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

Assistance in Guidewire Penetration
Time Frame: 1 day
The ability of the NovaCross™ micro-catheter to facilitate a guidewire successfully penetrating the proximal cap of the CTO
