IR, DRL Guidance
FDA has published a guidance, Information Requests and Discipline Review Letters, explaining how the agency will issue and use an information request (IR) and/or a discipline review letter (DRL) during the assessment of an original section 505(j) ANDA. The document does not apply to a supplement or an amendment to a supplement.
The guidance revises one issued 1/2022 to incorporate information on IRs and DRLs from the GDUFA 3 reauthorization.
