In recent times, the prevalence of respiratory diseases has dramatically increased due to a combination of lifestyle choices and environmental pollutants. Worldwide, asthma affects more than 300 million people, and lung conditions such as COPD kill more than 3 million people every year. The symptoms of these conditions can have significant impacts on the quality of life for patients and their caregivers, affecting them physically and mentally.

Clinical trials in the respiratory therapeutic area present a multitude of challenges and require the clinical expertise of a seasoned CRO. And when it comes to respiratory diseases such as asthma, cystic fibrosis and COPD, the nuances and additional technical knowledge required for the handling of various instruments for disease management can make executing successful respiratory clinical trials seem like a daunting task.

Find out how a decentralized trial can help you improve your patient experience, recruitment, and retention while producing overall higher data quality.

Why Choose Rho?

Committed to Respiratory Research

Rho has a deep and long-standing commitment to research in respiratory diseases, having supported groundbreaking research in inner-city asthma and peanut allergies beginning in 1997. Drawing on this dedication and exceptional experience, our project teams understand what it takes to successfully enroll and execute respiratory studies.

With any respiratory program, building and maintaining strong relationships is critical. For this reason, we make a concerted effort to keep our cross-functional respiratory teams together over the course of multiple studies—aiding development of our therapeutic indication expertise.

Along with conducting inpatient and outpatient studies, we have experience coordinating standard of care with study-specific procedures and assessments, as well as interacting with multidisciplinary care teams. Through our extensive expertise, we have developed strong relationships with high-performing and high-enrolling sites equipped with trained investigators and staff – allowing us to consistently meet or exceed our sponsors’ start-up timelines.

Our cross-functional, collaborative approach allows us to identify challenges earlier, de-risk your development strategy, and eliminate the missteps and delays often caused by silos and handoffs – ultimately ensuring a consistent program that runs smarter and more efficiently.

Rho not only gave Anthera a clear picture of how their team would fulfill the study needs, but showed their knowledge and expertise of the [Cystic Fibrosis] indication as well as the protocol in a way that made them a collaborative partner rather than a service provider.

Expertise in Action

Cystic Fibrosis

Rho has developed relationships with 35+ cystic fibrosis research centers (both TDN and non-TDN sites) and has led 8 cystic fibrosis studies and 2 marketing application submission efforts in just the past 3 years.

Following study start-up for a Phase III cystic fibrosis study, the Cystic Fibrosis Foundation Therapeutics Development Network (TDN) conducted a survey of participating clinical sites to assess their satisfaction with Rho. Some highlights include:

  • 100% of sites ranked Rho as good or excellent for 6 of the 7 questions asked. For the seventh question, 90% of sites ranked Rho as good or excellent.
  • On all questions, Rho scored higher than the TDN average.
  • “Rho is tremendous! Their people put in the extra effort to get our site initiated over a weekend in order to make it easier for a subject.”


Rho has supported more than 50 asthma trials over the past 3 decades and we offer full-service clinical trial solutions for adult and pediatric populations. We have proven metrics demonstrating study start-up and enrollment timelines that consistently exceed projections for our sponsors.

  • 50+ clinical studies
  • 700+ sites
  • 65K+ patients

As a measure of the value of Rho’s contributions to allergy and asthma research, Rho allergy and asthma staff have co-authored over 40 manuscripts, including several in high-impact journals, such as the New England Journal of Medicine, Nature Immunology, and Science Translational Medicine.
