Strategies for Regulatory Starting Materials Designation in Drug Development and Manufacturing

Life Sciences, Clinical Trials, Pharmaceutical Regulation, Pharmaceutical, Pharma Manufacturing & Supply Chain, Preclinical,
  • Thursday, May 07, 2020

The selection of drug substance regulatory starting materials (RSMs) and justification of their designation in the pharmaceutical supply chain has become an industry-wide focus as a measure of mitigating regulatory risks, as well as preventing unexpected rises in cost when transitioning from clinical to commercial supply chains.

In this webinar, the speakers will discuss expectations of regulators on the selection of RSM and the justification of their designation in the pharmaceutical supply chain. In addition, the scope of presentation of RSMs required in regulatory filings and how to prepare for “push backs” in the event of a major objection to the sponsor’s RSM designation will be examined.

The speakers will also summarize several case studies where pharmaceutical/biotech CMC teams worked with outsourcing partners to design and execute strategies, enabling successful risk mitigation on RSM “push backs” for global filing.
