Register a trial

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Aprocitentan 12.5 mg
Treatment: Drugs - Aprocitentan 25 mg
Treatment: Drugs - Placebo

Experimental: Aprocitentan 25 mg in Part 1 (double-blind) - Participants will receive aprocitentan 25 mg, orally, once daily in the morning for 4 weeks.

Experimental: Aprocitentan 12.5 mg in Part 1 (double-blind) - Participants will receive aprocitentan 12.5 mg, orally, once daily in the morning for 4 weeks.

Placebo comparator: Placebo in Part 1 (double-blind) - Participants will receive placebo (matching aprocitentan), orally, once daily in the morning for 4 weeks.

Experimental: Aprocitentan 25 mg in Part 2 (single-blind, single arm) - After 4-weeks in the double-blind randomized part (Part 1), participants will received 25 mg aprocitentan, orally, once daily in the morning for 32 weeks.

Experimental: Aprocitentan 25 mg in Part 3 (double-blind withdrawal) - After 32-weeks in the single-blind, single-arm part (Part 2), participants will be re-randomized and receive aprocitentan 25 mg, orally, once daily in the morning for 12 weeks.

Placebo comparator: Placebo in Part 3 (double-blind withdrawal) - After 32-weeks in the single-blind, single-arm part (Part 2), participants will be re-randomized and receive placebo (matching aprocitentan), orally, once daily in the morning for 12 weeks.

* Historical documentation in the participant's medical records on uncontrolled blood pressure despite at least 3 background antihypertensive medications within 1 year before screening visit;
* Treated with at least 3 antihypertensive therapies of different pharmacological classes for at least 4 weeks before the screening visit (Visit 1);
* Mean Sitting Systolic Blood Pressure (SiSBP) greater or equal to 140 mmHg measured by Automated Office Blood Pressure Measurement (AOBPM);
