About this study

The purpose of this study was to investigate the pharmacokinetics of MP-3180 (1 µmol/kg) compared to the pharmacokinetics of iohexol (5 mL of a 300 mg iodine (I)/mL solution) in healthy adult participants. The secondary objective was to evaluate the safety and tolerability of MP-3180 in healthy adult participants.

Read the detailed description

Single-dose pharmacokinetics were characterized in sixteen (16) healthy, adult male participants in this Phase 1, open-label study following the administration of a single, intravenous 1 µmol/kg dose over 2 minutes followed by 10 mL saline under fasting conditions. Iohexol (Omnipaque-300, 5 mL of a 300 mg I/mL solution) was also administered over 2 minutes followed by 10 mL of saline. The pharmacokinetics of MP-3180 and iohexol was assessed by statistical comparison of pharmacokinetic parameters derived from plasma concentration-time curves and urine recovery data.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total plasma clearance of MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. Total plasma clearance (the volume of plasma cleared of the drug over time) was calculated as: Clp = Dose/ AUC∞.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

  2. Renal clearance of MP-3180 and iohexol

    Urine samples were collected pre-dose (time 0) and 5 mL urine samples were collected each time the subject voided. The total volume of urine excreted was recorded until 12 hours post-dose, and analyzed using validated analytical methods. Renal clearance (the volume of plasma cleared of the drug by the kidneys over time) was calculated as: CLr = Ae/ AUClast, where Ae is the cumulative amount of analyte excreted in urine over the sampling interval.

    Measured: Pre-dose and each time the participant voided up to 720 minutes post dose

  3. Maximum Plasma Concentration (Cmax) for MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. Maximum plasma concentration (Cmax; measured in ng/mL) was directly determined from the concentration-time data.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

  4. Time to Maximum Plasma Concentration (Tmax) for MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. The time to maximum plasma concentration (Tmax; measured in hours) was directly determined from the concentration-time data.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

  5. The terminal rate constant for MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. The terminal rate constant (λz) was determined by linear regression of the terminal linear phase of the log plasma concentration-time profile.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

  6. Area under the plasma concentration-time curve from time zero to the time of the last quantifiable concentration for MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. The area under the plasma concentration-time curve (ng*hr/mL) was estimated from time 0 to the last measurable concentration using noncompartmental analyses.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

  7. Area under the plasma concentration-time curve from time zero to infinity for MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. The area under the plasma concentration-time curve (ng*hr/mL) from time 0 to infinity was calculated as: AUC∞ = AUClast + LQC/λz where LQC is the predicted concentration (based on the terminal regression) at the time of the last measurable concentration.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

  8. The elimination half-life of MP-3180 and iohexol

    Blood samples were collected and analyzed using validated analytical methods. The elimination half-life (the time required for the concentration of the drug to reach half of its original value) was calculated as t1/2 λz= ln(2)/ λz.

    Measured: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose

Secondary outcomes (2)
  1. Incidence of adverse events

    An adverse event (AE) was defined as any untoward medical occurrence in a study subject after study drug administration and that did not necessarily have a causal relationship with this treatment.

    Measured: 1, 3, and 8 hours after dosing, and within 2 weeks after the final study dose

  2. Number of laboratory values that fall outside of pre-specified normal ranges

    Blood samples were collected and analyzed for hematology and clinical chemistry. Out of range values were documented.

    Measured: Pre-dose and within 2 weeks after the final study dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MP-3180 and Iohexol comparator in people with Glomerular Filtration Rate and Acute Kidney Injury, run by MediBeacon at 1 site 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 8 inclusion and 17 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 23 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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?

Total plasma clearance of MP-3180 and iohexol (time frame: Pre-dose and the following times after dosing: 5, 10, 15, 30, 45, 60, 90, 120, 180, 240, 300, 360, 480 and 720 minutes post-dose). The study lists 8 primary outcomes in all. 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 23 Sep 2016.
