About this study

Official title: A 4-Week, Phase 2, Randomized, Double-Blind, Placebo-Controlled, Dose-Ranging, Parallel Group Study To Evaluate The Safety, Tolerability And Efficacy Of Once Daily PF-04971729 And Hydrochlorothiazide In Patients With Type 2 Diabetes Mellitus With Inadequate Glycemic And Blood Pressure Control

MK-8835-042 (B1521004) is designed to assess the safety and efficacy of an investigational drug, ertugliflozin (MK-8835, PF-04971729), in participants with type 2 diabetes and hypertension. Participants in the study will receive 1 of 5 treatments for 28 days (either placebo, 1 of 3 doses of ertugliflozin [1, 5, or 25 mg], or the approved drug hydrochlorothiazide [HCTZ]). The primary hypothesis of the study was that ertugliflozin was superior to placebo on the change from baseline in average, 24-hour systolic blood pressure (SBP) on Day 28.

  10. Baseline Seated, Triplicate Trough DBP

    Trough DBP was measured using an automated blood pressure device with the participant in a seated position for at least 5 minutes before and while the blood pressure measure is obtained.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ertugliflozin 1 mg, Ertugliflozin 5 mg and Ertugliflozin 25 mg in people with Diabetes Mellitus, Type 2 and 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 4 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 13 Sep 2018. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 13 Dec 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?

Baseline 24-hour Average Systolic Blood Pressure (SBP) (time frame: 24 hours). The study lists 2 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 NCT01096667, 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 13 Sep 2018.
