Detailed Description

Analysis of the effect of i.v. VAS203 on renal function and perfusion in healthy subjects.

Primary objective:

Possible adverse effect of VAS203 on the Renal Plasma Flow (RPF) and the Glomerular Filtration Rate (GFR) during and after 6 hours of constant-rate iv. infusion of 10 mg/kg VAS203.

Secondary objective:

To analyse the effects of VAS203 on

  • filtration fraction
  • hemodynamics (afferent and efferent resistance, intraglomerular pressure)
  • markers of kidney injury and renal function
  • systolic, mean and diastolic brachial blood pressure
  • Plasma Pharmacokinetic of VAS203 and its first metabolite.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: 0, 2h, 4h, 6h and 8 h after start of infusion
Renal plasma flow measurement by para-Amino-Hippuric-Acid Clearance Method
0, 2h, 4h, 6h and 8 h after start of infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
