A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Willing to participate and sign a written informed consent
- Patients on antiplatelet drugs (except aspirin or clopidogrel), statins, ACE inhibitor, angiotensin II receptor blocker (ARB), warfarin or other direct acting oral anticoagulants (DOACs) need to be stable at current dose for at least 2 weeks prior to the start of screening.
- Males and females ≥ 18 and ≤90 years old
- Medical history of chronic stable angina triggered by physical effort and relieved by rest or sublingual nitroglycerin. Patients with grade II and III stable angina based on Canadian Cardiovascular Society angina grading.
- Patients who agree and in the opinion of the investigator are able to withdraw all non-beta blocker and all non-calcium channel blocker anti-anginal medications. For those subjects who are on one beta blocker or one calcium channel blocker can keep their medication. And patients agree and are expected to be able to remain on this treatment regimen from Day -21 until the completion of the double-blind period in the opinion of the investigator. For patients who have to modify their anti-anginal treatment regimen to meet the above qualification criteria, health care provider who is responsible for the patient's cardiac care (if this is not the study doctor) must provide a form of agreement (verbal conversation, phone call, in writing or shown as referral) to the PI before the treatment modification. For patients who are not on beta blocker or calcium channel blocker or other antianginal medications, there is no requirement to start on antianginal medication.
- Documented history of coronary artery disease with one or more of the following conditions: History of previous myocardial infarction (previous MI that occurred and was diagnosed at least 3 months prior to start of screening). Ischemic heart disease determined by stress myocardial imaging examination (including nuclear stress test, cardiac stress MRI and echocardiography stress test). Clinically significant coronary stenosis ≥50% in any vessel detected by coronary angiography (or coronary CT angiography).
You likely can't join if
- Patients with only non-cardiac chest pain or cardiac chest pain not related to angina.
- Any family member or relative of the study site staff, sponsor or CRO.
- Patients with contraindication to, unable to, or with other co-morbidities that may prevent or interfere with the ability to perform ETT, in the opinion of investigator, including but not limited to: hospitalization for acute exacerbation of chronic lung disease within 4 weeks prior to the start of screening, current home oxygen use, needs for cardiac glycoside therapy, functionally limiting peripheral arterial disease, physical disability or other intercurrent illness such as acute respiratory infection/illness that, in the opinion of the Investigator or Sub-investigator, may interfere with the ability to perform ETT.
- Patients with any other severe or serious condition that, in the opinion of the investigator is likely to prevent compliance with the study protocol or pose a safety concern if the patient participates in the study.
- Patients whose QTcF (Fridericia’s method corrected QT interval) is >460 ms in male and >470 ms in female during supine 12-lead ECG at rest at screening or any time prior to randomization from Day -21.
- Patients with presence of electrographic or other abnormalities/factors that could interfere with exercise ECG interpretation or may lead to a false positive stress test (including but not limited to, Lown-Ganong-Levine Syndrome (LGL), Wolff-Parkinson-White Syndrome (WPW), left bundle branch block, ≥1 mm ST segment depression at rest, pacemaker rhythm etc.).

Clinically significant coronary stenosis ≥50% in any vessel detected by coronary angiography (or coronary CT angiography).
- Understand and be willing, able and likely to comply with all study procedures and restrictions and comprehends the Seattle Angina Questionnaire rating scales and diary cards.
- Women of child bearing potential: Female patients of child-bearing potential or male patients with partners of child-bearing potential must use highly effective birth control methods from the start of screening, until 3 months after the last dose of study medication (for details please refer to Appendix III). Female patients of child bearing potential must have negative pregnancy tests at screening visit [Day -21, quantitative serum human chorionic gonadotropin (β-hCG test)] and randomization visit (Day 1, urine pregnancy test).
- Patient must experience two or more angina episodes from Day-14 to Day 1, as the baseline frequency of angina. At least two of the angina episodes must be recorded by WCM (Other written forms of recording/reporting angina episodes may be acceptable only in situations and times that recording by WCM is impractical). In addition, patients are allowed to use short acting nitroglycerin for relief of angina.
- To be qualified, patients must have two qualifying ETTs on standard Bruce protocol on Day- 7 and Day 1. The qualifying ETTs are: ETTs must meet the positive ETT criteria (refer to ETT explanation section 1.6 and 3.2.4); Total exercise duration (TED) of the positive ETT is between 3-12 minutes of exercise; The difference in TED between the two ETTs must not exceed 15% of the longer one.
