Sample text

The stent provides a mechanical scaffold to keep a vessel open. This is a device MOA under the definition. The drug-eluting stent is coated with a drug that is intended to be slowly released from the stent after placement in the vessel to prevent the buildup of new tissue that would reocclude the artery. The pharmacological action of the drug in preventing new tissue buildup is a drug MOA. The PMOA of this product is attributable to the device component’s function of physically maintaining vessel lumen patency.

The regulations therefore describe a mechanism for sponsors to appeal jurisdictional designations. The sponsor may request the product jurisdiction officer to reconsider the decision by filing a written request for reconsideration within 15 days of receipt of the letter of designation. The request for reconsideration should not exceed five pages, and no new information may be included in the request. OCP is required to respond to the appeal in writing within 15 days of its receipt. 42 DETAILED REGULATORY APPROACHES TO DEVELOPMENT, REVIEW, AND APPROVAL In addition to designating the Center that will be assigned primary jurisdiction over the combination product, OCP may indicate in its RFD response that other Centers may collaborate or consult in the review as necessary.

To the outside observer this could make the designation process appear subjective and perhaps inconsistent, particularly when jurisdictional assignments for apparently similar products differ. In response to these types of concerns, the FDA amended its combination product regulations (5) to † † † define “mode of action” (MOA) and “primary mode of action” (PMOA); describe an algorithm to assign combination products to a Center for regulatory oversight when the Agency cannot determine with reasonable certainty which mode of action provides the most important therapeutic action of the combination product; require a sponsor, in its RFD, to base its recommendation of the Center with primary jurisdiction for regulatory oversight of its combination product on the PMOA definition and, if appropriate, the assignment algorithm.
