Dr. Nikolov assured committee members that the FDA recognized this concern and was working on it. “We appreciate the disconnect between the charge and the concerns of the community. I assure you that the issues brought up will be part of our discussions so we can get this [biosimilar pathway] implemented the right way.”
According to the FDA’s regulations, a biosimilar designation does not allow for nonmedical switching, something that could only happen under a related but distinct designation known as interchangeability. During the committee meeting on July 13, a FDA staffer said that the agency is currently developing guidance for an “interchangeable” designation and plans to have it available before then end of 2016.
