About this study

Official title: Double-Blind, Placebo-Controlled, Concentration-Escalating, Pharmacokinetic Study Evaluating the Systemic Absorption, Safety, and Efficacy of OMS201 in Subjects Undergoing Ureteroscopic Treatment of Ureteral- or Renal Collecting System-Located Stones

The objectives of the study are to assess the systemic exposure, safety and efficacy of three concentrations of OMS201 in subjects undergoing retrograde ureteroscopic removal of upper urinary tract stones.

Read the detailed description

The main objective is to estimate the systemic exposure of OMS201 in retrograde ureteroscopic treatment of upper urinary tract stones. Safety will be assessed by vital signs, laboratory values and adverse events. Exploratory efficacy measures will assess the effect of OMS201 on postoperative pain, duration of surgery and ease of placement of a ureteral access sheath.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing OMS201 in people with Urinary Calculi and Urinary Stones, run by Omeros Corporation at 4 sites in United States.

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 2 inclusion and 13 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 12 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. 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. 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 combined 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.

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?

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?

Peak systemic exposure. (time frame: Day of surgery). 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 12 Oct 2012.
