Beat the Odds in CNS Drug Development

Central Nervous System (CNS) drug development faces a high failure rate — 85% of Phase II–III studies fail due to disease complexity, high placebo response, and subjective assessments. Cytel helps address these challenges with advanced statistical methodologies, adaptive trial designs, and AI-driven analytics, helping you de-risk your trial and increase the probability of success.

CNS Drug Development Is Expensive — Avoid Costly Failures

Cytel is at the forefront of CNS drug development. Our solutions and proven expertise can guide you through the unique challenges faced within CNS drug development:

  • Unreliable Preclinical Models — Many animal models fail to replicate human CNS diseases, limiting their predictive value.
  • Difficult Clinical Measurements — Difficult clinical measurements lead to a reliance on surrogate endpoints.
  • Patient Adherence Issues — Cognitive and physical impairments make it harder for patients to follow treatment regimens.
  • Subjective and Variable Assessments — Many CNS measures lack standardization, are prone to bias, and reduce data reliability.
  • Need for Early Validation — Strong Proof of Mechanism (PoM) and Proof of Concept (PoC) are essential to de-risk late-stage failures.
