ANDA Sameness Evaluation Guidance
FDA has published a guidance, Sameness Evaluations in an ANDA — Active Ingredients, to assist applicants in preparing an ANDA by providing recommendations on demonstrating sameness between the active ingredient in a proposed generic product and its reference-listed drug. The document says FDA will refuse to approve an ANDA if it contains insufficient information to show that, among other things, the active ingredient of the proposed generic drug product is the same as that of the reference-listed drug.
“The ANDA applicant is responsible for providing sufficient information to demonstrate that the proposed generic drug product is the ‘same as’ the reference-listed drug with respect to the active ingredient,” the draft says. “FDA has broad discretion to determine whether an ANDA applicant has submitted information sufficient for the agency to reasonably conclude that the proposed generic drug product’s active ingredient is the same as the active ingredient of the reference-listed drug.”
