About this study
Official title: A Phase III, Randomized, Active-Comparator Controlled Clinical Trial to Study the Efficacy and Safety of MK-0954E in Japanese Patients With Essential Hypertension Uncontrolled With Losartan and Amlodipine Co-administration
This study is being done to evaluate the efficacy, safety, and tolerability of losartan potassium 50 mg (L50) + hydrochlorothiazide 12.5 mg (H12.5) + amlodipine besylate 5 mg (A5) (MK-0954E). The primary hypothesis is that L50/H12.5/A5 is more effective in lowering mean trough sitting diastolic blood pressure (SiDBP) after 8 weeks of treatment compared to L50+A5 in Japanese participants with essential hypertension who are not adequately controlled following an 8-week treatment with filter period study drug (L50+A5).

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Mean Trough Sitting Diastolic Blood Pressure (SiDBP)
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.
Measured: Baseline and Week 8
Percentage of Participants Who Experience ≥1 Adverse Event (AE)
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 10-week treatment and follow-up period were summarized by study drug received.
Measured: up to 14 days after last dose of study drug (up to 10 weeks)
Percentage of Participants Who Experience ≥1 Drug-related AE
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 10-week treatment and follow-up period were summarized by study drug received.
Measured: up to 14 days after last dose of study drug (up to 10 weeks)
Percentage of Participants Who Experience ≥1 Serious Adverse Event (SAE)
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 10-week treatment and follow-up period were summarized by study drug received.
Measured: up to 14 days after last dose of study drug (up to 10 weeks)
Percentage of Participants Who Experience ≥1 Drug-related SAE
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 10-week treatment and follow-up period were summarized by study drug received
Measured: up to 14 days after last dose of study drug (up to 10 weeks)
Percentage of Participants Who Had Study Drug Stopped Due to an AE
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 treatment period due to an AE regardless of whether or not they completed the study was summarized by treatment arm
Measured: up to 8 weeks
Secondary outcomes (1)
Change in Mean Trough Sitting Systolic Blood Pressure (SiSBP)
Sitting systolic 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.
Measured: Baseline and 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 10-week treatment and follow-up period were summarized by study drug received.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing losartan potassium + hydrochlorothiazide + amlodipine besylate (MK-0954E), Losartan potassium and Amlodipine besylate in people with Hypertension, run by Merck Sharp & Dohme LLC.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 27 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Mean Trough Sitting Diastolic Blood Pressure (SiDBP) (time frame: Baseline and Week 8). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01302691, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Mar 2019.
