About this study

Official title: Evaluation of the Effects of Shampoo RV3438G in Recurrent Squamous States and Maintenance of the Effects

The aim of the study is to evaluate, with clinical, biological and biometrological assessment methods, the effectiveness of RV3438G shampoo, after 2 weeks of short intensive treatment phase and also the effects of a maintenance phase of 8 weeks in association with a neutral shampoo, or with a gentle balancing shampoo, compared to a neutral shampoo used single.

This is a bicentric, comparative (during the maintenance phase), randomized, controlled and open study, in parallel groups conducted in subjects having mild to moderate recurrent squamous states, for 10 weeks.

  16. Tolerance of the test product RV3438G assessed by the investigator

    Determined by the subject's spontaneous reporting, the investigator's non-leading questioning and his/her clinical evaluation

    Measured: assessed at baseline and after 2, 6 and 10 weeks of use

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 7 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 30 Aug 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 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?

Efficacy of the test product RV3438G during the maintenance phase by the global evolution of the squamous state assessed by the investigator (time frame: Assessed after 8 weeks of use, during the maintenance phase). 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 NCT06578962, which also lists 3 linked publications.

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 30 Aug 2024.
