Clinical Trials


She thought her skin condition would keep her from staying in touch with her friends.

Now, she never misses a moment.

That is what drives us. Experience, Rho.

Dermatological conditions can cause patients physical, mental, and emotional distress. We believe that everyone should be able to feel comfortable in their own skin. Having supported more than 175 dermatology clinical trials, Rho is recognized as an industry leading CRO in the space. Serving as the statistical and clinical coordinating center for the NIAID funded Atopic Dermatitis Research Network (ADRN) since 2004, we fully understand the challenges prevalent in today’s dermatology landscape. While we are able to support a variety of indication-specific studies, we have a strong history with atopic dermatitis, alopecia areata, pruritus, and vitiligo trials. Our regulatory, biometrics, and government partnership expertise compliments our deep understanding of skin conditions to create a unique approach.

Decentralized Trial Solutions 

At Rho, we believe that the best decentralized solutions are patient-centric, customizable, and rooted in a robust Risk-Based Quality Management (RBQM) framework. With patient safety and patient centricity as our primary goal, we use our data-driven RBQM process to evaluate risk and make recommendations for the optimal decentralized solution for your clinical trial or program. When designing and executing decentralized solutions, our teams focus on ensuring patient safety, increasing patient engagement, and reducing patient burden. We have found decentralized solutions essential in successful dermatology clinical trials. Prioritizing the patient’s comfort is of the utmost importance during dermatology studies, and our decentralized approach ensures positive patient experience and study outcomes.

Everyone should feel comfortable in their own skin. Join us in our effort to bring comfort to those who need it.
