Eligibility
Key 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 = 140 mmHg despite treatment with stable (i.e., unchanged for =4 weeks), optimal or maximally tolerated doses of three or four antihypertensive drugs of different classes, including an ACEI/ARB, a long-acting dihydropyridine CCB, and a thiazide or thiazide-like diuretic. Participant with documented intolerance to any doses of CCBs may be eligible if receiving another class of antihypertensive medication at an optimal or maximally tolerated dose (referred to as triple background antihypertensive therapy. An optimal dose is defined as the highest dose taking in to account participant's documented comorbidities and tolerability per investigator's clinical judgment.

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).

Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception while taking study treatment and for 3 months after stopping medication. Highly effective contraception methods include:
* Total abstinence (when this is in line with the preferred and usual lifestyle of the participant. Periodic abstinence (e.g. calendar, ovulation, symptom-thermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
* Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or bilateral tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment.
* Male sterilization (at least 6 months prior to screening). For female participants on the study, the vasectomized male partner should be the sole partner for that participant.
* Use of oral, (estrogen and progesterone), injected, or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception.

In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.

Women are considered post-menopausal if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age-appropriate history of vasomotor symptoms). Women are considered not of childbearing potential if they are post-menopausal or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or bilateral tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of child bearing potential.

If local regulations deviate from the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the ICF.
24. History of hypersensitivity to any of the study drugs, excipients or drugs of similar class.

Summary
Brief summary
The purpose of this 20-week randomized double-blind study in patients with resistant hypertension (rHTN) is to evaluate the efficacy, safety, and tolerability, of different doses of XXB750 administered as subcutaneous (SC) injections, compared to placebo. Since all study participants will be patients with rHTN, all study treatments will be given on top of maximally tolerated background antihypertensive therapy recommended by international guidelines for treatment of HTN (i.e., a thiazide or a thiazide-like diuretic, an angiotensin converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB), and a long-acting dihydropyridine calcium channel blocker (CCB).
