About this study

CHRONOLOGICAL DESCRIPTION OF THE STUDY

  1. Information provided to study participants
  2. Collection of written informed consent
  3. Harvesting of myometrial biopsies
  4. Creation of tissue explants using myometrial biopsies
  5. Stimulation of the explants with LPS
  6. Study of the effect of SAR150640 (beta3-adrenergic agonist) on LPS-induced oxidative stress Moreover, demonstrating the ability of beta3-adrenergic receptor agonists to prevent the appearance of oxidative stress and its consequences on tissues, as a complement to previous studies, is an additional argument for the clinical development of this class of pharmaceuticals in the management of threatened premature delivery and labour induction.

What is being measured

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

  1. simultaneous assays of 4-amino-5-methylamino-2,7-difluorescein (DAF) / Dihydroethidium (DHE) markers by the technique of high pressure liquid chromatography

    In vitro measurement of the ability of SAR150640 to prevent the release of free radicals (oxidative stress) induced by an inflammatory stimulus on tissue explants of the human myometrium. The level of oxidative stress will be determined using simultaneous assays of DAF/DHE using HPLC. This reference technique for the overall evaluation of oxidative stress is perfectly mastered at the LPPCE (Laboratoire de Physiopathologie et Pharmacologie Cardiovasculaire et Experimentales)

    Measured: The biopsy of myometrium is done specifically for this study in a surgical unit after delivery of the child, in women with a normal pregnancy but requiring a caesarean

Secondary outcomes (1)
  1. Characterization of signalling pathways induced by oxidative stress during inflammation

    Characterization of the implication of NADPH oxidase (luminometry) and the subunits of NADPH oxidase (gp91, p22fox, p67phox, p47phox, p40phox as well as Rac1/2) and NO synthases (eNOS \& iNOS), as the source of the oxidative stress induced by an inflammatory stimulus, using Western blot

    Measured: The biopsy of myometrium is done specifically for this study in a surgical unit after delivery of the child, in women with a normal pregnancy but requiring a caesarean

Questions about this trial

What is this clinical trial studying?

A study testing myometrium biopsy in people with Pregnancy, run by Centre Hospitalier Universitaire Dijon at 1 site in France.

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 4 inclusion and 4 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 11 Aug 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 France. 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.

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?

simultaneous assays of 4-amino-5-methylamino-2,7-difluorescein (DAF) / Dihydroethidium (DHE) markers by the technique of high pressure liquid chromatography (time frame: The biopsy of myometrium is done specifically for this study in a surgical unit after delivery of the child, in women with a normal pregnancy but requiring a caesarean). 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 11 Aug 2016.
