Read the detailed description
This is a single arm, multicenter, OLE study designed to evaluate long-term safety, tolerability and efficacy of QCZ484, administered SC, once Q6M, in patients with HTN, who have successfully completed treatment period in the parent studies of the QCZ484 HTN program.
Participants at sites from the parent study will be offered the option to enroll in this extension study at the Month 12 visit upon successful completion of the parent study treatment.

Measured: Up to 66 months
Secondary outcomes (2)
Change in SBP and DBP assessed by ambulatory blood pressure monitoring
Change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) from Baseline (parent study) and from Day 1 of the OLE and at Months 12 and so on (every 12 months) assessed by assessed by ambulatory blood pressure monitoring (ABPM) - applicable only for the subgroup of participants who had ABPM in the parent study
Measured: Baseline (parent study), Day 1 (OLE study) and up to month 60 (OLE study)
Change in SBP and DBP assessed by office blood pressure measurement
Change in SBP and DBP from Baseline (parent study) and from Day 1 of the OLE and at Months 6, 12 and so on (Q6M) assessed by assessed by office blood pressure measurement (OBPM)
Measured: Baseline (parent study), Day 1 (OLE study) and up to month 66 (OLE study)
