Renal Function Impairment clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

A Single Centre Open Label Comparison of [I-123]-Ortho-Iodohippuric Acid (OIH) With [Tc-99m]-Mercaptoacetyltriglycine (MAG3) for Assessment of Renal Tubular Function

Start date: September 2012
Phase: N/A
Study type: Observational

Iodine-123 labelled ortho-Iodohippuric Acid ([I-123]-OIH) was used in the early 1970's as a kidney imaging agent or tracer that "lights-up" inside your body when scanned, but over the years its use has declined. The most commonly used tracer is Technetium-99m labelled Mercaptoacetyltriglycine ([Tc-99m]-Mertiatide or [Tc-99m]-MAG3). However, long-term shortages may threaten the supply of the radioactive substance Tc-99m in Canada and the world. As a result of such shortages, there is a need to identify other types of tracers that can be used for imaging. [I-123]-OIH may be an alternative. The purpose of this study is to examine the diagnostic performance characteristics of [I-123]-OIH in comparison to [Tc-99m]-MAG3.
