  • Adult, Older adult

Study population: Data from 33 physicians from different levels of hospitals were invited to provide information on patients who received MK-0954A and had pre- and post-treatment serum uric acid and lipid profile reports during the study period. Each physician could provide up to 30 clinical charts of patients matching the inclusion criteria for the study.

Who may be able to join

  • Participant was >20 years and <75 years of age on the index date (i.e., the date of initiating MK-0954A therapy)
  • Diagnosed with hypertension and had received MK-0954A 50/12.5 mg for at least 3 months
  • Had at least one serum uric acid measurements at baseline and one at 3 months after using MK-0954A 50/12.5 mg
  • Had the following records documented in the chart during the data collection period:
  • medical history and co-morbidities (if available)
  • sitting blood pressure, serum uric acid, lipid profile test results before and after using MK-0954A 50/12.5 mg
  • serum electrolytes, serum creatinine, and pre-meal sugar (if available)
  • prescription information of all antihypertensive regimens

Who cannot join

  • Had been treated with diuretic or angiotensin-receptor blockers (ARBs) 2 weeks before initiated treatment with MK-0954A 50/12.5 mg
  • Serum creatinine >2 mg/dL

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Feb 2022. 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.

Are results available for this study?

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?

Serum Uric Acid (SUA) Level (time frame: Baseline and Month 3). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Feb 2022.
