E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy and dose-response relationship of different doses of XXB750 SC compared to placebo in reducing the mean 24hr ambulatory systolic blood pressure (mean 24hr SBP) from baseline at Week 12. |
- |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the treatment effect of the highest XXB750 dose versus placebo in reducing the mean 24hr SBP from baseline to Week 12.
To characterize the dose-response relationship of XXB750 compared to placebo in the nocturnal systolic blood pressure (SBP) dipping at Week 12.
To evaluate the proportions of participants achieving ambulatory BP control (i.e., mean 24hr SBP < 130 mmHg and mean 24hr DBP < 80 mmHg) with respect to the dose-response relationship of the four XXB750 dose level groups compared to placebo at week 12.
To evaluate the safety and tolerability of the XXB750 regimens over 12 weeks of treatment and over the 20-week study period |

E.3 | Principal inclusion criteria |
1. Male and female participants who are = 18 years old. 2. Signed informed consent prior to participation in the study. 3. Apparent rHTN at screening (Visit 1) defined as uncontrolled BP with an office msSBP = 145 mmHg despite treatment with stable (i.e., unchanged for =4 weeks), maximally tolerated doses of three antihypertensive drugs of different classes, specifically an ACEI/ARB, a long-acting dihydropyridine CCB, and a thiazide or thiazide-like diuretic. Refer to Section 10.8 for minimum required doses of some commonly prescribed drugs in those classes. 4. Mean 24hr SBP =135 mmHg (measured by ABPM) at the end-of Runin-Visit (Visit 30) on treatment with maximally tolerated doses of an ACEI/ARB, a long-acting dihydropyridine CCB, and a thiazide or thiazidelike diuretic.
Additional inclusion criteria are described in the clinical study protocol. |

E.4 | Principal exclusion criteria |

Known history of secondary hypertension (moderate-to-severe obstructive sleep apnea without receiving CPAP therapy (either face mask or nasal device), renovascular hypertension, primary aldosteronism, pheochromocytoma, Cushing syndrome, aortic coarctation or other cause of secondary hypertension). 3. Estimated GFR <30 mL/min/1.73m2 using CKD-Epi equation at screening (Visit 1) or at end-of-run-in visit (Visit 30). 4. Serum potassium >5.0 mmol/L (or equivalent plasma potassium value) at screening or end-of-run-in visit (Visit 30). 5.

Clinically significant cardiac arrhythmias (e.g., ventricular tachycardia), high-grade AV block (e.g., Mobitz type II and third-degree AV block in absence of a pacemaker) within 6 months of screening according to investigator's judgement. 8. Chronic non-paroxysmal atrial fibrillation 9. Acute myocardial infarction (AMI) or unstable angina, or any history of ischemic or hemorrhagic stroke within 12 months of screening; or any percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) within 12 months of screening 10.

Participants receiving beta blockers and prostate-specific alpha blockers (e.g., tamsulosin) are allowed in the study only if those medications are being used for nonhypertension indications and benign prostatic hypertrophy, respectively. 14. Night shift workers. 15. History of presence of any other disease where the life expectancy is less than 3 years. 16. History of malignancy of any organ system (other than localized basal or squamous cell carcinoma of the skin or localized prostate cancer), treated or untreated, within the past 3 years, regardless of whether there is evidence of local recurrence or metastases. 17. Evidence of hepatic disease as determined by any one of the following:SGOT (AST) or SGPT (ALT) values exceeding 3x the upper limit of normal (ULN),or bilirubin >1.5 mg/dl at Visit1. 18. Use of other investigational drugs at the time of enrollment, or within 30 days or 5 half-lives of enrollment, whichever is longer. 19. History of drug abuse or alcohol dependency. 20. Lacking the ability to comprehend or follow instructions, or for any reason in the opinion of the investigator, a participant that would be unlikely or unable to comply with study protocol. 21. Concurrent enrollment in any other investigational drug or device trial (participation in non-interventional registries is acceptable). 22. Requiring prolonged/regular use of NSAIDs or other prohibited medications during of the study (i.e., required use for longer than 1 week). 23. Pregnant, nursing or planning to become pregnant (documented negative pregnancy test required within a maximum of 7 days prior to enrollment of all women of childbearing potential). Documentation of highly effective contraception is also required for women of childbearing potential (see below).
Additional exclusion criteria are described in the clinical study protocol. |
