Navigating the Small Molecule CMC Pathway: Strategies for Avoiding Regulatory Hurdles and Early Drug Development Pitfalls

Life Sciences, Pharmaceutical Regulation, Drug Discovery & Development, Preclinical,
  • Thursday, January 19, 2023

Navigating the small molecule CMC pathway from discovery to the clinic comes with its own set of challenges and regulatory hurdles. Once the lead candidate has been selected to move into development, what’s next? Bridging discovery and clinical development can present many questions and unknown challenges for drug developers:

  • What are some of the drug substance, drug product and clinical supply considerations in advancing a drug candidate towards a First-in-Human study?
  • Would an integrated drug substance and drug development approach be best for a clinical program?
  • How long does each critical step take before reaching the clinic?
  • What regulatory considerations does one need to be aware of?

With the stakes high, having trusted and experienced guidance at this stage can help streamline the pathway from discovery towards IND, reduce risk and improve the likelihood of clinical success.

Consulting group NGT BioPharm Consultants and Quotient Sciences have helped hundreds of customers achieve their IND milestones and beyond. By offering strategic guidance and integrated services spanning the entire development pathway, both have supported programs with lead candidate selection, drug substance, drug development, biopharmaceutics, clinical and regulatory services, all focused on accelerating development and expediting strategies to address regulatory expectations toward clinical development.

Join the featured speakers as they share their expertise around the challenges and considerations that drug developers may face in early development. Mapping out key early development milestones, they will share strategies on how they’ve helped customers remove obstacles off the critical path, reduce development risks and shorten the small molecule CMC pathway to the clinic.

Mark A. Krook, Head, Early Development, NGT BioPharma Consultants

Mark A. Krook is a pharmaceutical executive with more than 35 years of experience, covering all aspects of small molecule CMC research and development, from early drug development through commercial manufacturing.

Mark began his pharmaceutical career at The Upjohn Company (finally becoming Pfizer) as a process chemist working on API process development for clinical and commercial needs, eventually moving into the leadership of global, multi-site, chemical process R&D organizations with responsibilities for both laboratory and pilot plant facilities. From there he transitioned to portfolio management, providing broad technical, strategic and governance oversight for cross-functional CMC activities within a highly diversified portfolio of development projects.


Upon joining Johnson & Johnson (Janssen), he was responsibile for the API development group in the US and took over leadership of the global CMC Portfolio Management function with accountability for CMC activities across the entire small molecule development spectrum (preclinical to lifecycle management). His most recent role was in Janssen Supply Chain, leading End-to-End Strategy, where he helped orchestrate the lifecycle management of commercial products, via improved strategies, oversight and governance, with attention on delivering the best product possible.

Since retiring from J&J, Mark has joined the leadership team of NGT BioPharma Consultants and is also an independent consultant.
