This document discusses guidelines for formal meetings between drug and biologics sponsors/applicants and the FDA. There are three types of meetings - Type A for stalled development programs, Type B for key milestones, and Type C for other issues. Type A meetings should occur within 30 days, Type B within 60 days, and Type C within 75 days of an FDA request. Meeting requests must include an agenda, questions, and lists of attendees to allow the FDA to assess utility and identify necessary staff. The guidelines aim to promote efficient management of meetings between regulators and industry.
