Why is each in process test required? ? How were the acceptance limits chosen? ? Why were the inprocess tests identified as critical to product quality? ? What scaleup experience does the sponsor have with the unit operations in this process? QBR: Risk Summary ? NTI drug ? Classified as a nonNTI drug, risk score = + 0 ? Classified as an NTI drug, risk score = +1 ? Dosage Form ? Simple Dosage Form, risk score = + 0 ? Other Dosage Forms and NTI drugs, risk score = + 1 ? Development Report ? If the sponsor submits a development report that addresses the FDA’s questions: Risk score = + 0 ? Solution and IR Products: Product Development Report ? Other Dosage Forms: Product and Process Development Reports ? Insufficient or missing development report, risk score = + 1 ? If the application is of high overall quality ? Less than or equal to 2 cycles, risk score = + 0. ? Greater than 2 cycles, risk score = + 1 QBR: RiskBased Conclusion ? Should the application be approved? ? What postapproval waivers/mitments are appropriate for this product? ? If the total risk score is less than or equal to 1 ? CBE0 and CBE30 changes may be in annual reports ? Many PAS to CBE 30 ? If the total risk score is greater than 1 ?
