Choose the right perspective
Match the person's product experience to yours, since CMC questions for small molecules, biologics and cell or gene therapies differ a great deal. Also consider whether your decision concerns early development filings or post-approval changes, and ask which stage the person has handled most.
Questions to take into the conversation

- 02How do you handle a manufacturing site or process change after approval across different health authorities?
