About this study

Official title: Assessment of Pharmacokinetics, Pharmacodynamics Profile and Tolerance of P03277 in Healthy Subjects and Patients With Brain Lesions

The primary objective of this study was to evaluate the safety (clinical and biological) and pharmacokinetics (plasma and urine) profile of P03277 following single administration at ascending dose levels in healthy subjects.

Read the detailed description

This single-center, single ascending dose, phase I/IIa study was divided into 2 parts, involving both healthy subjects and patients with brain lesions:

  • Study Part I included healthy subjects: double-blind, randomized, placebo control;
  • Study Part II included patients with brain lesions: open-label.

In Part I, the following 6 dosing groups were investigated:

  • Group 1: 0.025 mmol/kg
  • Group 2: 0.05 mmol/kg
  • Group 3: 0.075 mmol/kg
  • Group 4: 0.1 mmol/kg
  • Group 5: 0.2 mmol/kg
  • Group 6: 0.3 mmol/kg

Healthy subjects were included and were then administered with P03277 or placebo and were to undergo MRI examination according to the randomization scheme.

In Part II, the following 4 doses groups were investigated:

  • Group 7: 0.05 mmol/kg
  • Group 8: 0.075 mmol/kg
  • Group 9: 0.1 mmol/kg
  • Group 10: 0.2 mmol/kg

Patients with brain lesions were included and were then administered with P03277 and underwent MRI examination.

Being tested
P03277, Placebo

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • P03277Drug

    Also called Gadopiclenol

    Part I: P03277 was administered intravenously with a flow rate ranging from 0.5 to 2 mL/s.

    Part II: P03277 was administered intravenously with a flow rate of 2 mL/s.

  • PlaceboDrug

    Also called NaCl 0.9%

    Part I: Placebo was administered intravenously with a flow rate ranging from 0.5 to 2 mL/s.

    Part II: Placebo was administered intravenously with a flow rate of 2 mL/s.

Study groupRoleWhat they receive
Part I (Phase I)ExperimentalIn each dose group (0.025, 0.05, 0.075, 0.1, 0.2 and 0.3 mmol/kg), 9 healthy subjects were to be included: 6 subjects received P03277 and 3 subjects received placebo in one single intravenous administration.
Receives: Drug: P03277; Drug: Placebo
Part II (Phase IIA)ExperimentalIn each dose group (0.05, 0.075, 0.1 and 0.2 mmol/kg), all 3 patients received one single intravenous administration of P03277.
Receives: Drug: P03277

What is being measured

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

  1. Pharmacokinetic (PK) Parameter Cmax

    Cmax = maximum concentration measured. Blood samples were taken to assess the P03277 concentration.

    Measured: From baseline (30 minutes before injection) to 24 hours post-injection

  2. PK Parameter T1/2

    T1/2 = terminal elimination half-life of the compound. Blood samples were taken to assess the P03277 concentration.

    Measured: From baseline (30 minutes before injection) to 24 hours post-injection

  3. PK Parameter Cl

    Cl = total clearance. Blood samples were taken to assess the P03277 concentration.

    Measured: From baseline (30 minutes before injection) to 24 hours post-injection

  4. PK Parameter Vd

    Vd = volume of distribution. Blood samples were taken to assess the P03277 concentration.

    Measured: From baseline (30 minutes before injection) to 24 hours post-injection

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing P03277 in people with Healthy Volunteers and Brain Lesion, run by Guerbet at 1 site in Belgium.

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 0 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 14 May 2021. 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 Belgium. 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 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?

Yes. Results are posted in the registry (first posted 12 Jul 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Pharmacokinetic (PK) Parameter Cmax (time frame: From baseline (30 minutes before injection) to 24 hours post-injection). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03603106, which also lists 1 linked publication.

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 14 May 2021.
