About this study
Official title: Effect of Renal Impairment on Pharmacodynamics and Pharmacokinetics of RO4998452: A Multiple-center, Open-label, Parallel Group Study Following Single Oral Dosing of RO4998452 to Type 2 Diabetes Patients With Varying Degrees of Renal Impairment.
This 4 arm study will investigate the pharmacodynamics and pharmacokinetics of RO4998452 in type 2 diabetes patients with varying degrees of renal impairment. Eligible patients will be divided into 4 groups, with normal renal function, or mild, moderate or severe renal impairment. All patients will receive a single oral dose of RO4998452 in the fasted state.The anticipated time on study treatment is <3 months (single dose study)and the target sample size is <100 individuals.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RO4998452 in people with Diabetes Mellitus Type 2, run by Hoffmann-La Roche at 2 sites in 2 countries.
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 4 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 2 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States, Russia. Whether a site is taking part right now should be confirmed with that site. See every site.
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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Creatinine clearance; Pk parameters; adverse events (time frame: Days 1-3). 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 2 Nov 2016.
