CS8635 20/5/12.5mg and placebo
Olmetec® Plus 20/12.5mg and placebo
Participants receiving Olmetec® Plus 20/12.5mg (OM/HCTZ 20/12.5 mg) for the 4-week, Run-in Period but who do not meet their blood pressure goals(Non-responders) could start receiving this triple fixed dose combination therapy (CS8635 20/5/12.5mg (OM/AML/HCTZ 20/5/12.5mg) + placebo) in randomized, 8-week, double-blind Period. The non-responders finishing double-blind treatment could continue the 8-week Open-label Period with CS8635 40/5/12.5mg (OM/AML/HCTZ 40/5/12.5 mg).
Participants receiving Olmetec® Plus 20/12.5mg (OM/HCTZ 20/12.5 mg) for the 4-week, Run-in Period but who do not meet their blood pressure goals(Non-responders) could start receiving this dual fixed dose combination therapy (Olmetec® Plus 20/12.5mg (OM/HCTZ 20/12.5mg) + Placebo) in randomized, 8-week, double-blind Period.
