Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: LAS41007
All patients will be instructed to apply the IMP twice daily, once in the morning and once in the evening. Per application, not more than 1.5 g of the IMP should be applied, which is sufficient to cover a total area of 75 cm2 (corresponding to 3 single TAs, each with a size of 25 cm²) in maximum. The IMPs will be applied for 90 days in maximum.
Drug: LAS41007
Topical gel, to be applied twice daily (mornings and evenings), for up to 90 days. Generally 0.5 g gel (pea-sized amount of gel) per application will be sufficient to cover an overall area of 25 cm².
Active Comparator: LASW1510
All patients will be instructed to apply the IMP twice daily, once in the morning and once in the evening. Per application, not more than 1.5 g of the IMP should be applied, which is sufficient to cover a total area of 75 cm2 (corresponding to 3 single TAs, each with a size of 25 cm²) in maximum.
