Refuse-To-Receive Practices


To ensure the consistency in the content, to reduce the time that would be spent by FDA reviewers and to minimize the approval timelines to be included in the substantially complete ANDA, FDA have set up Refuse-To-Receive guidelines, which are very vital to the manufacturers/ANDA holders to be complaint with all RTR standards for an ANDA.

FDA will refuse to receive the ANDA that means will reject the substantially incomplete ANDA in case of non-compliance to RTR standards, which will lead to loss of 25% of ANDA fee and also delay in receiving the approval subsequently delay in market entry. Therefore, to submit error-free application right at first time, an applicant must have complete understanding of FDA’s Refuse-to-receive standards for ANDA.

Interpretation of FDA’s RTR guidelines and adhering to the requirements is quite challenging for the manufacturers/ANDA holders. Freyr can help client in preparation, review and submission of ANDA as per RTR standards and FDA requirements within the timelines.
