MK-0954E Phase III Long-Term Study in Participants With Hypertension (MK-0954E-356)

This study has two parts. In the first part, the efficacy and safety MK-0954E (losartan potassium 50 mg [L50] (+) hydrochlorothiazide 12.5 mg [H12.5] (+) amlodipine besylate 5mg [A5]) will be evaluated and compared to the efficacy and safety of MK-0954H (L50/H12.5) in Japanese participants. In the second part, the safety and tolerability of long-term use of open-label MK-0954E in participants with hypertension will be evaluated. The primary hypothesis is that MK-0954E is more effective in lowering mean trough sitting diastolic blood pressure (SiDBP) after 8 weeks of treatment compared to MK-954H (L50/H12.5 mg) in Japanese participants with essential hypertension who are not adequately controlled following a 8-week treatment with filter period study drug of MK-954H.

Primary outcomes

  1. Change in Trough Sitting Diastolic Blood Pressure (SiDBP)-Double-Blind Treatment Period

    Time frame: Baseline and Week 8

    Sitting diastolic blood pressure was measured by automated sphygmomanometer pre-dose on Day 1 (baseline) and at 24 ± 2 hours after the last study drug administration at Week 8. The difference between the baseline and Week 8 assessments was calculated and summarized by treatment arm.

  2. Percentage of Participants Who Experience 1 or More Adverse Events (AEs)- Double-Blind Treatment Period

    Time frame: up to Week 8

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. The percentage of participants who experienced at least 1 AE during the 8-week double-blind treatment period were summarized by study drug received.

  3. Percentage of Participants Who Experience 1 or More Drug-Related AEs- Double-Blind Treatment Period

    Time frame: up to Week 8

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. Percentage of participants that experienced at least 1 AE that was reported as possibly, probably, or definitely related to the study drug by the investigator during the 8-week double-blind treatment period were summarized by study drug received.

  4. Percentage of Participants Who Experience 1 or Serious Adverse Events (SAEs)- Double-Blind Treatment Period

    Time frame: up to Week 8

    An SAE is any AE occurring at any dose or during any use of Sponsor's product that does the following: results in death; is life threatening; results in persistent or significant disability/incapacity; results in or prolongs an existing inpatient hospitalization; is a congenital anomaly/birth defect; is a cancer; is associated with an overdose; is another important medical event. The percentage of participants who experienced at least 1 SAE during the 8-week double-blind treatment period were summarized by study drug received.

  5. Percentage of Participants Who Experience 1 or More Drug-Related Serious Adverse Events (SAEs)- Double-Blind Treatment Period

    Time frame: up to Week 8

    An SAE is any AE occurring at any dose or during any use of Sponsor's product that does the following: results in death; is life threatening; results in persistent or significant disability/incapacity; results in or prolongs an existing inpatient hospitalization; is a congenital anomaly/birth defect; is a cancer; is associated with an overdose; is another important medical event. Percentage of participants that experienced at least 1 SAE that was reported as possibly, probably, or definitely related to the study drug by the investigator during the 8-week double-blind treatment period were summarized by study drug received.

  6. Percentage of Participants Who Had Study Drug Discontinued Due to an AE - Double Blind Treatment Period

    Time frame: up to Week 8

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. The percentage of participants who had study drug stopped during the 8-week double-blind treatment period due to an AE regardless of whether or not they completed the study was summarized by treatment arm.
