Development of CNS Treatments

CNS drugs have had relatively lower success rates owing to a multitude of factors: poor predictive value of pre-clinical efficacy models, limited understanding of relevant mechanism of action, inability of large molecules to cross the BBB and underappreciation of the heterogeneity of neurobiological phenotypes.

Unique Challenges With CNS Development

Because our team has been in the industry for so long, we understand that CNS programs have many challenges. The following roadblocks are frequently encountered during development:

  • Limited understanding of target engagement and selection of an animal model with insufficient predictive value.
  • Inefficient drug delivery systems and, therefore, brain availability too low to reach efficacious levels.
  • Heterogeneity of neurobiological phenotypes.
  • Challenging regulatory pathway and competitive landscape
  • Long clinical development

KreaMedica’s Solutions For CNS Drug Development

KreaMedica’s core expertise in CNS drug development and services spans right from validating pre-clinical efficacy data across relevant animal models and optimizing formulation development to ensure target engagement, through to IND-enabling toxicology studies and beyond.

  • Gap analysis to ensure that the molecule and the drug delivery systems are exhaustively characterized.
  • Development and execution of a regulatory strategy
  • Appropriate animal model selection including robust study designs that factor in most phenotypes and off-target effects.
  • Our program managers will ensure that all cross-functional dependencies and timelines are aligned to propel your program on the critical path.

Meet Our CNS Expert

Dave Hawver

Before becoming a consultant, Dave spent twenty-three years reviewing nonclinical data submitted to the FDA/CDER Divisions of Neurology 1 and 2 in support of 266 commercial INDs, 22 NDA/BLAs, 203 Pre-INDs, and 113 Research INDs. In this role he reviewed nonclinical study reports (pharmacology, safety pharmacology, ADME, toxicology, genotoxicity, carcinogenicity, reproductive and developmental toxicity, and other toxicity studies), draft protocols (carcinogenicity, juvenile animal study, combination toxicity), meeting packages (Pre-IND, EOP1/2/3, pre-NDA), requests for clarification, Investigator’s Brochures, Informed Consent Documents, and responses to full or partial clinical holds.

With a PhD from Columbia University in Neuroscience and Pharmacology and postdoctoral studies at NIH on the mechanisms underlying bipolar disorder and Alzheimer’s disease, in addition to his extensive FDA experience, Dave is uniquely positioned to provide guidance on the non-clinical development of your CNS drug.
