CNS Clinical Trials
Early-phase clinical trials for central nervous system (CNS) drugs are highly complex, requiring teams with both therapeutic and technical expertise to address the scientific, operational, and recruitment challenges unique to this field.
With over two decades of experience conducting CNS studies across a wide range of early-phase research areas, our experts deliver the precision, consistency, and speed your program requires.
Clinical Trials for Neurological, Psychiatric, and Cns-Active Compounds
We are a proven CNS Center of Excellence, offering fully integrated, early-phase drug development services designed specifically for the complexities of central nervous system (CNS) therapeutics. With over 30 years of experience and more than 200 CNS studies completed, we support sponsors from preclinical research through clinical proof of concept, all within a single, streamlined organization.
Our CNS expertise spans a broad range of neurological and psychiatric indications, including programs focused on cognition, mood, pain, sleep, and behavioral health. We work across both healthy volunteer and patient populations, using validated models and cognitive assessments to generate high-quality data that drives informed decisions in early pharmacology, safety, and proof-of-concept outcomes.
Led by experienced Principal Investigators, clinicians, and neuroscientists, our team is equipped to design and execute even the most complex early-phase CNS trials. With integrated capabilities in toxicology, clinical pharmacology, bioanalysis, formulation, and manufacturing, Altasciences reduces handoffs, accelerates timelines by up to 40%, and ensures data continuity every step of the way.
From first-in-human (FIH), proof-of-concept (POC), and other clinical pharmacology studies to specialized models―including human abuse liability, pain, driving simulation, and novel CNS compound evaluation―our early-phase capabilities provide the flexibility to evaluate complex CNS programs with precision and confidence.

We partner with Cambridge Cognition, a global leader in digital neuroscience technology, to deliver validated, non-invasive test batteries that assess key cognitive domains such as attention, memory, executive function, and psychomotor performance.
Cognitive Domains
- Complex attention
- Learning and memory
- Language
- Executive function
- Social cognition
- Perceptual-motor function
Driving Simulation:
Through our partnership with Cognitive Research Corporation (CRC), we offer state-of-the-art driving simulation studies that assess the effects of drugs on real-world performance in a controlled, low-risk environment. Our on-site simulators provide accurate and reproducible data comparable in sensitivity to on-road testing, at reduced cost and timelines.
