Balancing the Scientific & Human Aspects of Neuroscience Clinical Research

Neuroscience research demands an appreciation for both the human-focused and scientific aspects of clinical research. Worldwide approaches each clinical trial with a thoughtful, patient-centric plan.


Worldwide Clinical Trials has helped advance neuroscience research since the advent of cholinesterase inhibitors in the 1970s. Today, we continue that decades-long tradition of clinical trial excellence by combining our extensive experience with our persistent desire to innovate and excel – and it shows in our many long-term partnerships and collaborations throughout the industry with small to large organizations. We’ll help take your compound from Phase I through Phase III, and you’ll get the full force of our medical and scientific prowess in the form of collaborative, customized project teams with phase- and indication-specific expertise.

Rare neurological diseases each have unique hurdles for developing compelling outcomes assessments that can demonstrate efficacy with small patient populations. Worldwide is a leader in rare disease recruitment, novel endpoint development, and innovative study designs. We deliver specialty studies that apply our overarching knowledge in neurological conditions and rare diseases to thoughtful study designs, respecting patient communities and generating the data sponsors need to advance their compound to market.
