Clinical Trials

Neurology & Psychiatry

She thought neurological symptoms would take away her work.

She just designed the fall line.

That is what drives us. Experience, Rho.

neurology and psychiatry

When it comes to the neurologic and psychiatric therapeutic areas, history would have us believe the future of these clinical trials is going to be mired in more of the same – failure.

Over the past decade, 99% of Alzheimer’s drug trials have failed and the likelihood of approval in neuropsychiatry indications is barely 6%. And with nearly a quarter of all Americans having at least one CNS disorder and the majority of effective treatments dating back to the 1950s, the need for better CNS disease research solutions globally is clear.

The way we see it, past failure isn’t a problem. It’s an opportunity.

An opportunity to ask ‘why?’ When history tells us that participant compliance is one of the biggest challenges to the success of CNS clinical trials, we listen, learn, and adapt in a way that only a neuroscience CRO could.

An opportunity to improve participant retention and study adherence by creating a trial experience that’s adaptable and as smooth as possible. By incorporating patient and caregiver needs and concerns into the initial study design process, as well as decentralized clinical trial needs, we are able to mitigate and minimize their burden before it becomes a problem – ensuring participants are fully engaged at each and every step of our CNS clinical research.

An opportunity to unite our global team of experts. With over 130 years of collective experience in the central nervous system (CNS) therapy area, including more than 350 clinical studies, 3,000 sites and 70,000 patients, no matter what challenges may arise during the development of your drug … our collaborative team of experts stand ready to utilize their learnings to enhance the success of your drug development program.

An opportunity to utilize the past to advance our future. Our cross-functional collaborative approach as a CNS focused CRO 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’s flexible and runs smarter and more efficiently.

An opportunity to set a higher standard for CNS clinical research by overcoming past challenges and accelerating the patient path to relief and your path to approval.

And the perfect opportunity to do what we do best – create a better experience for our partners within their central nervous system (CNS) therapy area.

Global Reach

Our global client solutions will ensure you reach your patients, wherever they are. With international capabilities that span 5 continents, we provide full-service capabilities to execute your clinical development programs and trials across the globe.

I have been conducting mental health trials for over 20 years and my experience with Rho is phenomenal. Rho stands out far above other CROs as their teams are truly dedicated and committed to sites, understanding protocol complexities within mental health, and patient safety. With Rho, I have worked with the same CRA throughout a trial when industry norm is having 3-5 CRAs over the course of a trial. Rho CRAs have been very experienced and always responsive to study needs. I highly recommend Rho to any Sponsor.
