High Blood Pressure (Hypertension)
QGC001-3QG2 Enrolling

Hypertension Research Trial (56 Weeks)


Age: 18 Years

Adults (men and women) with a diagnosis of primary hypertension for at least 6 months, may qualify to participate. Individuals must currently be treated with 2 antihypertensive classes of drug, or currently treated with at least 3 antihypertensive classes of drug including a diuretic, at the maximum tolerated doses of those medications (with no change in the antihypertensive regimen for at least 6 weeks). Systolic BP between 140 mmHg and 179 mmHg (inclusive) at screening, while on current chronic antihypertensive treatments, is also required.

Participants will receive investigational oral medication (active study drug) or placebo. Investigational medication and study-related assessments will be provided at no cost. Reimbursement for study-related expenses may be provided.

Study participation will last about 56 weeks and involve about 12 visits to the study centre, plus 2 phone visits.

Adult men and women (at Screening).

Diagnosis of primary HTN for at least 6 months prior to Screening and:

Currently treated with 2 antihypertensive classes of drug (difficult-to-treat subjects), or currently treated with at least 3 antihypertensive classes of drug including a diuretic (treatment resistant subjects), at the MTDs of those medications (ie, the subject can tolerate the current dose of each medication but higher doses have caused or may worsen side effects), with no change in their antihypertensive regimen (drug, dose, or schedule) for at least 6 weeks, and with medication adherence ≥80% during the Run in Period.

Have a successful ABPM measurement with a mean systolic daytime ABP >135 mmHg after the Run-in Period while on their current chronic antihypertensive treatments. An ABPM is successful if at least 21 daytime readings and 6 nighttime readings have been successfully recorded.
Women of childbearing potential and nonsurgically sterile male subjects who are sexually active must agree to use an approved highly effective form of contraception from the time of informed consent until 30 days post dose. Approved forms of contraception include hormonal intrauterine devices, hormonal contraceptives (oral birth control pills, depo, patch, or injectable) together with supplementary barrier methods such as condoms or diaphragms with spermicidal gel or foam.
Women of childbearing potential must have a negative serum pregnancy test result at Screening and a negative urine pregnancy test result at the Inclusion Visit (Visit 2B, Day 1)

Exclusion Criteria:

Target population:

Subjects with uncontrolled primary HTN despite being treated with at least 2 classes of antihypertensive therapies, at the MTDs (difficult-to-treat or treatment-resistant patients).
