Explain the formal meeting process with FDA

"Sponsor Actions: meeting request, meeting information package, preparation for meetings (contingency planning), Meeting conduct, Meeting Follow-up (issuance of minutes) (*never add new mater during the meeting). FDA Actions: Review meeting request & notify sponsor of outcome (grant denial), pre-meeting/internal meeting in advance of sponsor meeting, issue preliminary answers to questions to the sponsor 24-48 hours before the meeting, Issue official meeting minutes issued within 30 days"

What are examples of drug development tools?

"animal modles, ii. biological markers: a characteristic that is objectively measured and evaluated as an indicator of normal biologic processes, pathogenic processes or biological responses to a therapeutic intervention. Thus, a change to a biomarker following treatment with the drug product can predict or identify safety problems related to the drug or reveal a pharmacological activity expected to predict an eventual benefit from treatment. They may reduce uncertainty in drug development and evaluation by producing quantitative predications about drug performance. iii. clinical outcome assessments: (PRO: patient reported outcome) 1) PRO: an instrument that captures the outcomes of drug intervention during a clinical trial from the patient's perspective (change in pain or depression from before the therapy compared to over time after therapy). This is a questionnaire that is self-administered by the patient or through interview but other parties that report on patient perspectives. The questionnaires measure characteristics or constructs that should have a sound theoretical basis and be relevant to the patient group in which they are to be used. Must be thoroughly tested for its use; reports from validated PRO instruments can be used to support drug approval and claims in approved medical product labeling. iv. Clinician rating scales/caregiver rating scales

What is the intial review process when FDA receives an NDA?

(1)Once received, FDA has 60 days to determine whether the application is sufficiently complete to allow for a substantive review. If it is complete it will be filed on day 60, if not FDA can "refuse to file" (RTF) and will issue a formal RTF letter by Day 60 that will proved the reasons for the decision. FDA can also RTF sections of the NDA. If an applicant strongly disagrees with FDA's decision to RTF an application, the applicant has 30 days to request a meeting with FDA - following the meeting then the applicant can request that the agency file the application "over protest". The date of filing for "over protest" will be 60 days from the date the applicant requested the meeting. (2)For applications that are file: FDA performs an "initial filing review" by day 60 to identify filing review issues which are substantive deficiencies or concerns that may have significant impact on FDA's ability to review or approve the application. (3) Then applicant will receive the day 74 letter (mandated by PDUFA). This states the date FDA received the application (date the review clock begins); provides the review time line and includes an action date, when FDA will provide a decision on the application as well as dates when the applicant can expect or receive feedback from the review division on proposed labeling and Postmarketing requirements/commitments; also identifies the review classification granted by FDA. (under PDUFA V "program" will also state whether the division is considering convening an advisory committee meeting; (4)During the review FDA may ask the applicant for additional information "solicited information" or the applicant may submit additional information on its own initiative "unsolicited information". If the new information constitutes an amendment FDA may determine that an extension of the review PDUFA action date is needed to review the information. Only 1 three month extension can be given per review cycle. For solicited information that requires an amendment, FDA will also provide a new timeline for feedback on proposed labeling and postmarketing requirements or commitments.

What is FDA's review process when the initial NDA has been review and no RTF was issued?

FDA review process: (A) When the application is validated and received it is routed to the regulatory project manager (RPM). The RMP will ask supervisory team leaders from appropriate disciplines to assign reviewers. The first review task is to determine from each specific discipline whether the application is fileable. Review team is made up of clinical, pharmacology and toxicology, chemistry, clinical pharmacology, etc. if clarification is needed the specialist can communicate to the sponsor through an information request (IR) or advice letter (AD) these are handled via email, telephone or direct mail. The RPM facilitates these communications. (B) DR letters can be issued "discipline review" after each discipline reviewed their section. They are used sparingly (C) For some applications outside experts are needed.(D) FDA then determines whether any bioresearch monitoring (BIMO) or current GMPs inspections are required prior to approval. (i) Preapproval inspection: FDA can inspect manufacturing facilities (CGMP inspection) and/or sites where the drug was tested in nonclinical or clinical studies (BIMO inspections). They are likely to occur: (a)NMEs or original BLAs (b) Priority reviews (c) The first application filed by an applicant (d) For-cause inspections (ie. one clinical trial site had a significantly better trial outcome than other sites) (e) Original or supplemental applications, if the cGMP status is unknown (ie. more than 2 years since the domestic facility was last inspected, or the establishment is new and has yet to be inspected by FDA or another global regulated authority. (E) FDA will then make a determination whether postmarketing requirements or commitments are necessary. If yes, this is communicated to the applicant to discuss and agree on specific studies. (F) FDA also review the labeling in parallel to the step above. FDA makes sure that the labeling reflects the product's safety and efficacy and allows physicians, healthcare providers and consumers to understand if the drug outweighs the risk. (G) Finally FDA will decide if they are ready to take action on the application. If it's a new molecular entity or an original BLA the office director must sign, all others the division director can sign. (H) FDA decision on an application: (1)Approval letters: issued when FDA has determined that the drug is safe and effective- can be acceptably manufactured and is appropriately labeled: this is the date you can start to market the drug for sale. (2)Complete response: lists all deficiencies identified by FDA and identifies the steps the applicant should take to address these deficiencies in a future submission before the application can be approved.

Where you can find all the RLDs and use RLD to submit and ANDA through a suitability petition. (2)The generic drugs list in the orange book are given two ratings "A" or "B". A rating: no in vivo bioequivalence issue is known; Active ingredients or dosage form present a potential bioequivalence problem but applicant's approved application contains scientific evidence (through in vivo and in vitro studies) establishing bioequivalence of the product to the selected RLD. B rating: FDA has documented bioequivalence problems or a significant potential for such problems and no adequate studies demonstrating bioequivalence have been submitted to the agency; FDA has an insufficient basis to determine therapeutic equivalence (quality standards are inadequate); the drug products are under regulatory review. (3)Pharmacist also use this to find generic drugs that are approved for the RLD so it's cheaper for the patient.
