Summary

This phase 3 trial tests whether a new drug called HCP1803-4 can safely lower blood pressure in adults with essential hypertension. Participants are randomly assigned to receive either the new drug or a control drug. The study measures changes in sitting blood pressure over time to see if the new drug works better or as well as existing options.
