Symptomatic Trial of Angina Assessment Prior to Revascularization (ORBITA-STAR)

September 21, 2023 updated by: Imperial College London

Symptomatic Trial of Angina Assessment Prior to Revascularization: A Placebo-controlled Experiment on Symptoms in Stable Coronary Artery Disease

The principal objective of this research is to determine whether symptoms, induced by confirmed experimental ischaemia, can help us predict which patients will respond to PCI.

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.

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

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 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

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
Placebo controlled similarity score during low pressure balloon occlusion of the coronary artery
Time Frame: 30 Days
Similarity Score (1-10) (Higher Score = Better Outcome)
30 Days

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
Change in angina symptom score
Time Frame: 30 Days
Fractional Change in Angina Frequency (0-1) (Lower Score = Better Outcome)
30 Days
Change in treadmill exercise time
Time Frame: 30 Days
30 Days
Change in treadmill time to chest pain
Time Frame: 30 Days
30 Days
Angina severity as assessed by Canadian Cardiovascular Society Class
Time Frame: 30 Days
Canadian Cardiovascular Society Class (0-IV) (Lower Score = Better Outcome)
30 Days
Physical limitation, angina stability, quality of life, angina frequency, freedom from angina as assessed with the Seattle Angina Questionnaire.
Time Frame: 30 Days
Seattle Angina Questionnaire, (Lower Score = Better Outcome)
30 Days
Quality of Life assessed with the EQ-5D-5L questionnaire
Time Frame: 30 Days
(Lower Score = Better Outcome)
30 Days
Change in dobutamine stress echocardiography score
Time Frame: 30 Days
(Lower Score = Better Outcome)
30 Days
Need for anti-anginal medication introduction and uptitration
Time Frame: 30 Days
30 Days
Anxiety as assessed by the GAD-7 Score
Time Frame: 30 days
Generalised anxiety and depression - 7 Score. (Lower Score = Better Outcome)
30 days
Depression as assessed by the PHQ-9 Score
Time Frame: 30 days
Patient Health Questionnaire - 9. (Lower Score = Better Outcome)

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 16, 2020

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.
May 1, 2023

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.
