Clinical Trial Summary

Primary Objective:

To assess the effects of SAR407899 on coronary vasomotor function using the coronary flow reserve (CFR) in participants with microvascular angina (MVA) and/or persistent stable angina despite angiographically successful percutaneous coronary intervention (PCI).

Secondary Objectives:

• To assess the effects of SAR407899 on quality of life using Seattle Angina Questionnaire physical limitation scale (SAQ-PL) in participants with MVA and/or persistent stable angina despite angiographically successful PCI.

• To assess the safety of SAR407899 in participants with MVA and/or persistent stable angina despite angiographically successful PCI with a focus on identified risks such as hypotension and orthostatic hypotension.

• To assess SAR407899 plasma concentrations in MVA participants and/or persistent stable angina despite angiographically successful PCI.

Description:

The total duration of study per participant was:

• up to 9 weeks for participants with previous coronary artery angiography or coronary computed tomography angiography (CCTA) within 24 months prior to screening with up to 4 weeks screening period, 3 weeks titration phase, 1 week maintenance period, and 1 week follow-up after the last investigational medicinal product administration.

or

• up to 11 weeks for participants with previous coronary artery angiography or CCTA between 24 months and 5 years prior to screening who need CCTA during screening period with up to 6 weeks screening period, 3 weeks titration phase, 1 week maintenance period, and 1 week follow-up after the last investigational medicinal product administration.

In participants with stenting, a minimum diameter stenosis of <10% is required.

or Coronary computed tomography angiography (CCTA) with finding of non-obstructive coronary arteries within the past 24 months* in participants without previous percutaneous coronary intervention (PCI).

*Note: in cases of clinically suspected progression of atherosclerosis as per the Investigator, a more contemporary (i.e., 6 months) evidence should be provided.

or CCTA performed during screening period, with finding of non-obstructive coronary arteries, in participants diagnosed with microvascular angina (MVA) and stable angina without previous PCI who did not have a coronary angiogram or CCTA in the previous 24 months but between 24 months to 5 years.

• Baseline global coronary flow reserve (CFR) (measured during the study) assessed by 13N-ammonia or 82Rubidium positron emission tomography (PET) scan <2.0.

Exclusion criteria:

• Any use of nitrates (except short-acting nitrates) and/or dipyridamole and/or phosphodiesterase type 5 (PDE 5) inhibitors within one week prior to baseline PET scan or anticipated to be used during the study.

• Esophageal dysmotility or esophagitis.

• Participants with acute coronary syndrome (ACS) (myocardial infarction [MI] and/or unstable angina) in previous 3 months.

• Unsuccessful or incomplete coronary revascularization with residual obstructive stenosis or coronary artery disease (CAD) progression in native vessels as documented on invasive coronary angiography (>=50% stenosis) within 24 months of enrollment.

• Percutaneous coronary intervention performed at the time of an ACS (MI or unstable angina) in the previous 12 months.

• Recent PCI within the past 3 months.

• Participants with history of coronary artery bypass grafting (CABG).

• Recent (<=3 months) major surgery (i.e. valvular surgery, surgery for congenital heart disease), stroke, transient ischemic attack [TIA], sustained ventricular arrhythmia, clinically significant structural heart disease (moderate-severe valvular disease, hypertrophic cardiomyopathy, congenital heart disease, pulmonary hypertension).

• Regional local flow abnormal perfusion defects at baseline PET scan*.

*Note: if contemporary evidence with invasive coronary angiography or CCTA demonstrates non-obstructive coronary arteries or if the regional local flow abnormal perfusion defect on PET scan is consistent with previous studies then participant qualifies for the study.

• Participants with cardiac conduction abnormalities (second or third degree atrioventricular [AV] block, sick sinus syndrome, symptomatic bradycardia, sinus node disease) except in participants fitted with a functioning pacemaker.

• History or known carotid stenosis:

• Carotid stenosis (>50%) or

• History of carotid stenosis in participants with previous symptoms.

• Contraindication or known hypersensitivity to adenosine or regadenoson.

• Contraindication to aminophylline.

• Contraindication to vasodilator stress PET scan and/or CCTA if CCTA needed during screening.

• Inability to discontinue treatment with methylxanthines treatment within 24 hours prior to PET scan.

• Participant unable to read, understand and fill a questionnaire without any help (eg, partially visually impaired or blind).

• Systolic blood pressure (SBP) <110 millimeter of mercury (mmHg) at baseline.

• Presence at baseline of symptomatic orthostatic hypotension (SBP decrease of 20 mmHg or more at Minute 3 or Minute 5 between seated and standing position), or asymptomatic orthostatic hypotension with a decrease in SBP equal or greater than 30 mmHg at Minute 3 or Minute 5 when changing from the seated to the standing position.

• Renal impairment with estimated glomerular filtration rate (eGFR) <50 milliliter/minute/1.73 square meter (mL/min/1.73 m^2) at screening and baseline.

• Drug-induced liver injury related criteria:

• Underlying hepatobiliary disease.

• Alanine Aminotransferase (ALT) >3 times the upper limit of normal (ULN).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Uncorrected Global Coronary Flow Reserve (CFR) at Week 4	Absolute change from baseline to Week 4 in uncorrected global CFR, as assessed by the central core laboratory. The global CFR is the ratio of absolute myocardial blood flow (MBF) at stress over that at rest. The MBF was assessed by 13N-ammonia or 82Rubidium positron emission tomography (PET) scan.	Baseline, Week 4
Secondary	Change From Baseline in Angina-induced Physical Limitation Assessed Using Seattle Angina Questionnaire Physical Limitation Scale (SAQ-PL) at Week 4	The SAQ-PL measures how common daily activities representing low, medium, and high exertional requirements were limited by angina (9 items). It was scored by assigning each response an ordinal value, beginning with 1 for the response that implied the 'lowest level of functioning' to 5 for 'not at all limited', and summing across the 9 items. The score of 9 items was then transformed to 0-100 range by subtracting the lowest possible scale score, dividing by the range of the scale and multiplying by 100. The range of scores was 0 to 100, with higher scores indicates better functioning. A change of 10 points was considered to be clinically important.	Baseline, Week 4
Secondary	Pharmacokinetic Parameter: SAR407899 Plasma Concentration		Day 1, 8, 15, 22, and Day 29
