Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Erythema at the Patch Test Site is Evaluated for Each Participant

    Erythema Scoring Scale with 0 being no visible erythema and 5 being bullous reaction.

    Time frame: 3 weeks

Secondary outcomes

  1. Sensitization Reactions

    Erythema Scoring Scale with 0 being no visible erythema and 5 being bullous reaction. Allergic Dermal Sensitization Potential - Erythema will be evaluated at the patch site for only the test material (positive and negative control will not be evaluated). Sensitization reactions will be determined at the patch test site after a two week rest period for each participant (similar to a "wash-out period"). The patch test site will be tested on the same study subject population, but using a virgin test site.

    Time frame: 5 weeks
