Study Description

This is a multicenter, randomized, double-blind, factorial design Phase 2 study to evaluate the pharmacodynamics, safety and tolerability of a combination of QCZ484 and inclisiran compared to QCZ484, inclisiran, and placebo in participants with hypertension and concomitant hypercholesterolemia. The study will last up to 12 months and has three periods:

* Eligibility will be assessed during the screening period including 2 screening visits. Some eligibility criteria will be confirmed at the Baseline/Randomization visit.
* Eligible participants will be randomized to receive a combination of QCZ484 and inclisiran, QCZ484, inclisiran or placebo once on Day 1 at the Baseline/Randomization visit.
* Afterwards, participants will enter the safety follow-up period. Eligible participants who complete the treatment period have the option to participate in an open-label extension study instead of entering the safety follow-up period.
