The Role of Q1/Q2 (Q3) Deformulation in ANDAs
Q1/Q2 is a term that refers to the assessment of inactive ingredients that is part of all ANDA filings. In the chemistry, manufacturing, and controls (CMC) portion of Sec. 314.94, “Content and format” of an ANDA, it states that “an applicant must identify and characterize the inactive ingredients in the proposed drug product and provide information demonstrating that such inactive ingredients do not affect the safety or efficacy of the proposed drug product.” For some complex ANDAs, Q3 similarity data may also be required.
Q1/Q2 Sameness Evaluation
Q1 Assessments:
Demonstrate qualitative sameness
Identify an inactive ingredient
Provide information about grade and the chemistry of each inactive ingredient
Q2 Assessments:
Demonstrate quantitative sameness
Determine the quantity/concentration of an inactive ingredient
FDA has typically found differences of +/-5% acceptable
Q3 Similarity
Q3 Assessments:
Confirm physicochemical similarity to the RLD
Parameters may include appearance, pH, globule size distribution, rheological behavior, drug polymorphic form, drug release, etc.
