Outcome Research to Confirm the Anti-anginal Effect of T89 in Patients With Stable Angina

Conditions

Chronic Stable Angina Pectoris angina pectoris

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a multi-center, double-blind, randomized, placebo-controlled, parallel-group phase 3 clinical study to confirm the safety and efficacy of T89 in patients with stable angina pectoris, with an extended open-label period to evaluate the long-term safety of T89. This study includes three main periods: the first study period is a 3-week single-blind qualifying run-in period to screen eligible stable angina patients by exercise tolerance test (ETT). The second study period is a 8-week double-blind treatment period to evaluate the efficacy and safety of T89 in patients with stable angina by ETT. And, the last study period is a 44-week open-label period to observe long-term use safety of T89.

Inclusion Criteria	Exclusion Criteria
1. Willing to participate and sign a written informed consent 2. Males and females ≥ 18 and ≤90 years old. 3. Medical history of chronic stable angina triggered by physical effort and relieved by rest or sublingual nitroglycerin. 4. 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 beta blockers and/or calcium channel blockers, they are able to keep only one beta blocker or one calcium channel blocker (acceptable calcium channel blocker: amlodipine, diltiazem, verapamil or nicardipine), but not both, and subjects 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. 4.1) 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. 4.2) 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. 5. Documented history of coronary artery disease with one or more of the following conditions: 5.1) History of previous myocardial infarction (previous MI that occurred and was diagnosed at least 3 months prior to start of screening). 5.2) Ischemic heart disease determined by stress myocardial imaging examination (including nuclear stress test, cardiac stress MRI and echocardiography stress test). 5.3) Clinically significant coronary stenosis ≥50% in any vessel detected by coronary angiography (or coronary CT angiography). 6. 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. 7. Women of child bearing potential: Female patients of child-bearing potential or male patients with partners of child-bearing potential must use appropriate birth control from the start of screening, until 3 months after the last dose of study medication. 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). 8. 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). 9. To be qualified, patients must have two qualifying ETTs on standard Bruce protocol on Day- 7 and Day 1. The qualifying ETTs are: 1. ETTs must meet the positive ETT criteria; 2. Total exercise duration (TED) of the positive ETT is between 3-12 minutes of exercise; 3. The difference in TED between the two ETTs must not exceed 15% of the longer one. * For the qualifying ETTs, in patients with permitted baseline ST-segment depression at rest (\<1 mm at 80 msec after the J point), qualifying ST-segment depression during ETT will be defined as additional ST-segment depression ≥1 mm (at 80 msec after the J point) below the resting value.	1. Patients with only non-cardiac chest pain or cardiac chest pain not related to angina. 2. 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. 3. 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.). 4. Patients with history of any coronary revascularization procedure (e.g. PCI or CABG) within 2 months prior to the start of screening. 5. Patients who had unstable angina, or myocardial infarction within the recent 3 months prior to the start of screening. 6. Patients with ongoing NYHA Classes III-IV congestive heart failure. 7. Patients with angina pectoris at rest at screening. 8. Patients with rapid atrial fibrillation at screening (rest heart rate \>120/min) or any time prior to randomization from Day -21. 9. Patients with ongoing myocarditis, pericarditis, thrombophlebitis or pulmonary embolism or who have recovered from these conditions \<1 month prior to screening.

Patients who have to be on digoxin, digitalis, or other herbal products containing Danshen (Radix Salviae Miltiorrhizae, RSM), Sanqi (Radix Notoginseng, RN) or Ginkgo biloba during the single-blind screening and/or double-blind treatment period. 15. 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. 16.
