About this study

Official title: Target Involvement and Exploratory Biomarkers Investigations in Healthy Volunteers and in Patients With Type 2 Diabetes Mellitus

The purpose of this study is to evaluate the vascular function and biomarkers in healthy volunteers and type 2 diabetic patients.

Read the detailed description

The present interventional study will be performed in 3 groups of healthy volunteers of different ages and in type 2 diabetic patients without an investigational medicinal product administrated.

What participants receive

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

  • OtherDrug

    Healthy volunteers will be selected within 3 weeks before inclusion (Day 0). The investigations will be performed on 2 days (Day 1 (D1) and Day 2 (D2)): vascular endothelial function assessment and blood collection for biomarker investigation on Day 1 and Case Report Form (CFR) on Day 2.

    Then, subjects will be discharged at the end of the last investigation day (Day 2).

    All the participants have received two pharmacological agents (NIMP) :

    • Acetylcholine : administered subcutaneously (by iontophoresis) to assess maximal vascular endothelial function.
    • Adenosine : administered intravenously during MRI for the measurement of CFR.
  • OtherDrug

    Type 2 diabetic patients will be selected within 3 weeks before inclusion (Day 0).

    The investigations will be performed on 2 days (Day 1 (D1) and Day 2 (D2)): vascular endothelial function assessment and blood collection for biomarker investigation on Day 1 and CFR on Day 2.

    Then, subjects will be discharged at the end of the last investigation day (Day 2).

    All the participants have received two pharmacological agents (NIMP):

    • Acetylcholine : administered subcutaneously (by iontophoresis) to assess maximal vascular endothelial function.
    • Adenosine : administered intravenously during MRI for the measurement of CFR.

Individual data sharing
Yes: Qualified scientific and medical researchers can request access to anonymized patient-level and study-level clinical trial data. Access can be requested for all interventional clinical studies: * used for Marketing Authorization (MA) of medicines and new indications approved after 1 January 2014 in the European Economic Area (EEA) or the United States (US). * where Servier is the Marketing Authorization Holder (MAH). The date of the first MA of the new medicine (or the new indication) in one of the EEA Member States will be considered for this scope. In addition, access can be requested for all interventional clinical studies in patients: * sponsored by Servier * with a first patient enrolled as of 1 January 2004 onwards * for New Chemical Entity or New Biological Entity (new pharmaceutical form excluded) for which development has been terminated before any Marketing authorization (MA) approval.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Other in people with Type 2 Diabetes Mellitus, run by Institut de Recherches Internationales Servier at 1 site in Germany.

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 45 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 25 Jul 2024. 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 Germany. 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?

Guanylate triphosphate cyclohydrolase (GTP-CH) investigations (time frame: Day 1). 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?
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 25 Jul 2024.
