New Drug Application (NDA) Submissions - Overview

New Drug Application (NDA) 505 b (1) and 505 b (2) is the application process through which pharmaceutical drugs for human use are approved by the United States Food and Drug Administration (US FDA). As per the legislation laid down in the US Federal Food, Drug, and Cosmetic Act, Regulatory pathways to approve new drugs are the 505(b)(1) NDA pathway and 505(b)(2) NDA pathway. The 505(b)(1) NDA pathway is used to obtain new drug approval for new drugs with previously unapproved active components. An NDA application through this pathway should contain full reports of investigations on safety and effectiveness. The 505(b)(2) NDA Regulatory pathway is another Regulatory route, and applications through this pathway should contain full reports of investigations of safety and effectiveness, but where at least some of the information required for approval comes from studies not conducted by the applicant and for which the applicant has not obtained a right of reference. Also, the 505(b)(2) New Drug Application route is used for applications with a change in dosage form, change in strength, and change in the route of administration for the drugs that were evaluated and approved by the FDA as part of other NDAs.

For most of the sponsors, the challenging is to understand the FDA regulations, identifying the right Regulatory pathway for their drug development case, and defining the right Regulatory strategy for the NDA filing process. For an NDA submission, all mandatory information required as per Federal Regulations must be submitted by the sponsor. In case the sponsor fails to submit adequate information, the US FDA may Refuse to File (RTF) the NDA, due to which the sponsor cannot move forward unless additional information is submitted to comply with the Agency’s requirements. Apparent knowledge of the guidance detailing the reasons for RTF of a New Drug Application and its review process will save investment (agency fee) and an ample amount of time for sponsors during the NDA filing process.

Freyr assists the sponsors with end-to-end Regulatory support for the NDA process, starting from pre-NDA meetings to submission of NDA annual reports and further lifecycle management of the product.
