Understanding the Importance of Clinical Trials in Dermatology Treatments

Dermatology trials have unique characteristics, including visible endpoints (e.g., skin lesions or pigmentation), conditions that follow seasonal patterns, and skin-of-color considerations. These, along with the use of photography and imaging in dermatology clinical trials, add complexity to these studies.

Why do Clinical Trials Matter?

These trials play a crucial role in accelerating dermatological science, for example by translating discoveries in skin barrier physiology and skin microbiome research into approved therapies.

For instance, head-to-head studies compare new treatments with others already in use, and add-on trials test how new options work when added to standard care. These trials determine whether a new therapy should replace existing care, and often influence future treatment guidelines, helping raise the standard of care.

Lastly, trial results contribute to the safety profiling of different products and therapies, shedding light on how these perform in the long term and in real-word scenarios. This reduces uncertainty and ensures data quality in dermatology trials meets regulatory standards.

To better understand the importance of clinical trials in dermatology, let’s look at what these studies can contribute to the current state of this medical specialty.

The Current State of Dermatology Treatments

Major Indications & Unmet Needs

Dermatology trials target high-prevalence conditions like atopic dermatitis, psoriasis, acne, photoaging, and hidradenitis suppurativa. These studies also help develop new treatments for diseases such as vitiligo and alopecia areata.

Evidence Gaps

Evidence gaps in dermatology are a challenge to outcome equity and broad clinical adoption. For example, a review of clinical trials completed between 2017 and 2021 showed that less than 22% of studies included Black/African American participants.

Other areas where data is limited include pediatric treatment, long-term safety insights, and comparative effectiveness studies, for instance, comparing the long-term effect of biologics in psoriasis.

Innovations

The latest innovations involve topical delivery systems using nanotechnology, systemic small molecules like JAKs that regulate immune response in psoriasis, vitiligo, and others; and precision biologics that target personalized biomarkers. That’s in addition to wearable monitors and AI-based tracking devices, which are increasingly used during clinical trials in dermatology.

How Are Dermatology Trials Designed?

First, trial endpoints are set. How are endpoints selected in dermatology trials? Based on what outcomes matter most for a given condition or product claim. There are standardized endpoint sets for dermatological conditions (e.g. psoriasis studies often use Psoriasis Area and Severity Index (PASI), whereas atopic dermatitis uses Eczema Area and Severity Index (EASI).

Endpoints are measured using validated scales that assess severity, improvement, or response. For example, trials targeting aesthetic skin concerns may use Global Aesthetic Improvement Scale (GAIS). This initial step in trial design helps ensure that results are consistent and comparable. By clearly defining how endpoints are selected in dermatology trials, researchers create a framework that regulators, clinicians, and patients can trust.

Trial design also requires setting placebo groups or active comparators, to determine the relative efficacy of a new treatment against no treatment, or against standard treatment. Some trials are designed as add-on studies, where a new treatment is tested alongside an existing therapy to assess whether this combined approach provides an extra benefit.

The choice of instruments and imaging in dermatology clinical trials is also part of trial design: tools are selected ensuring they capture the specific outcomes needed to answer the study’s key questions. Choosing the right imaging tools and standardizing their use ensures consistent measurements across participants and sites, which is essential for maintaining high data quality in dermatology trials.

Trial design also involves participant selection and stratification, using factors like age, gender, Fitzpatrick skin type, or health condition, which provides insights into how different groups respond.

Barry Skillington explains – “At Atlantia, we invest upfront in time and effort on specific trial designs coupled with open dialogues with our clients and experts in the field to ensure the highest quality trials at the best possible budget for our clients.”

Ethical Considerations in Dermatology Clinical Trials

When designing a study in this field, there are several common ethical considerations in dermatology clinical trials that must be accounted for. For example, facial photography and lesion imaging could raise privacy concerns, so protocols must include informed consent for dermatology imaging, and participants must be made aware of data use and storage procedures and of the potential use of data in publications. However, every effort is made to minimize unnecessary exposure to any participant. Also, trial subjects are made aware of any potential risks such as inflammation, irritation, etc.

Balancing the scientific need for controls with patient welfare is a central ethical consideration in dermatology trials. Many studies now include early rescue protocols to minimize untreated condition duration, so that patients in placebo groups aren’t left with visible or uncomfortable symptoms longer than necessary.

Diversity, equity and inclusion are other important ethical concerns. Where possible, participants should be recruited across a wide range of skin phototypes to ensure that the treatments tested are safe and effective for all patients. Inclusion also means addressing access barriers, like travel costs or limited trial sites.

Lastly, dermatological conditions account for 30% of pediatric consults, so ethical trial design requires ensuring appropriate assent, parental consent, and minimizing the caregiver burden during the study.

Accounting for these ethical considerations in dermatology clinical trials ensures integrity, patient safety, and inclusivity.

The Future of Dermatology Clinical Trials

The future of dermatology clinical trials will strongly feature the following themes:

• Precision dermatology, with the inclusion of biomarkers or endotypes in participant stratification toidentifylikely responders early and improve trial efficiency. 
• Digital & decentralized models that rely on smartphone imaging, wearables, and home assays via tele-dermatology widen access and increase retention.
• Advanced designs like adaptive trials, Bayesian methods, and synthetic control arms reduce time to market while keeping research scientifically robust.
• AI-assisted phenotyping & endpoints, with technologies that support automated lesion detection and severity scoring, as well as objective phenotype classification. Because these technologies offer bias mitigation and reproducible outcomes, their use in dermatology diagnosis is only set to increase, with this market tripling its size by 2029.

FAQs

1. What makes clinical trials in dermatology different from other specialties?

Dermatology studies rely on visible endpoints, photography, and seasonal changes, which make trial design more complex than in other medical fields.

2. Which dermatology trial endpoints are most commonly used – and why do they matter?

Endpoints like PASI, EASI, and assessment scales like IGA or SCORAD, measure severity and treatment impact. These endpoints matter because they help researchers determine whether a product or treatment is effective and offer clinically meaningful benefits.

3. How is imaging used in dermatology clinical trials, and how is privacy handled?

Imaging tools are used to objectively measure how skin conditions or lesions change. Privacy protection is these trials involves protocols for data de-identification, secure storage, obtaining informed consent specifically for dermatology imaging, personnel training on data privacy matters, and compliance with relevant regulations, like GDPR or HIPAA.

4. How are participants recruited and retained in dermatology clinical trials – especially for diversity?

Recruitment typically starts with pre-screening, followed by a more detailed screening, and on-site or online health assessments to confirm eligibility. Established CROs that conduct dermatology trials will have a recruitment funnel that addresses the under-representation of diverse populations. Trial retention hinges on a variety of factors, like flexible visit options, decentralized methods, the use of custom participant apps, protocol design, ongoing support, and regular communication.
