About this study

Official title: Evaluation of the Effect of a Lotion on Antidandruff and on Mediating Microbiome Rebalance Versus Vehicle and Reference on Volunteers

Edit Brief Summary: To evaluate the NaP lotion effect to decrease dandruff scoring and microbiome rebalance.

Detailed Description: Dandruff is a common scalp disorder affecting almost half of the population of any gender and ethnicity. Skin microflora, in particular Malassezia genus, plays a key etiological role which was demonstrated in many studies.

Read more

Malassezia restricta was found as the major fungal species present on the scalps with or without dandruff; while the two main bacterial species found on the scalp surface were Propionibacterium acnes and Staphylococcus epidermidis. Dandruff seems correlated with a higher incidence of Malassezia restricta and Staphylococcus epidermidis and a lower incidence of Cutibacterium acnes.

Also, the link between dandruff and a higher level of scalp surface lipoperoxidation has been recently described. In fact, dandruff scalp surface is also characterized by higher amounts of squalene monohydroperoxide (SQOOH) and malondialdehyde. MDA is a late biomarker derived from sebaceous unsaturated free fatty acids. Some bibliographic elements suggest that these lipid biomarkers could trigger dandruff.

The main objective of that clinical study is to study the effect on dandruff of a leave-on formulation of anti-fungus NaP associated with anti-oxidant VitCG versus vehicle and versus reference leave-on anti-fungus alone Octopirox, all associated with a neutral shampoo.

Questions about this trial

What is this clinical trial studying?

A study testing NaP1%+VitCG3% leave-on lotion (formula 1256103) and reference Octopirox 0.25% (formula 1256149). in people with Dandruff, run by L'Oreal at 1 site in Portugal.

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 20 inclusion and 48 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: looking for participants now, as of the sponsor's last update on 7 Feb 2025. 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 Portugal. 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact AUDREY GABY GUENICHE, PharmaD and phD (+33660992467 ext. +33, audrey.gueniche@loreal.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Global score of dandruff status of the scalp: evaluation of adherent and non-adherent dandruff according (time frame: Day 0 and Day 28). 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 7 Feb 2025.
