Summary

This document is a Complete Response Letter (CRL) from the FDA for New Drug Application (NDA) 218506, outlining deficiencies that prevent approval in its current form. It addresses issues related to product quality, proprietary name, facility inspections, and requires a comprehensive safety update.

Key points

  • The applicant must provide satisfactory responses to the deficiencies conveyed by the FDA following a pre-approval inspection of the manufacturing facility.
  • The applicant must include the date(s) of the facility’s response(s) to the FDA Form 483 in their complete response.
  • The applicant must resubmit the proposed proprietary name when responding to all application deficiencies.
  • The applicant must include a safety update as described at 21 CFR 314.50(d)(5)(vi)(b) when responding to the deficiencies.
  • The safety update must include data from all nonclinical and clinical studies/trials of the product under consideration, regardless of indication, dosage form, or dose level.
  • The applicant must describe in detail any significant changes or findings in the safety profile.
  • The applicant must incorporate new safety data into sections describing discontinuations due to adverse events, serious adverse events, and common adverse events, presenting new data from studies/clinical trials for the proposed indication in the same format as the original submission.
  • The applicant must present tabulations of new safety data combined with original application data.

Deficiency summary

The FDA issued a Complete Response Letter for NDA 218506 due to significant deficiencies identified during a facility inspection, requiring satisfactory responses prior to resubmission.

A comprehensive safety update, including detailed data analyses and case report forms, is also required as per regulatory guidelines.

Findings

Unresolved Facility Inspection Deficiencies

Severity: critical

FDA conducted an expedited, risk-based review of the available information from the inspection and determined that the deficiencies represent significant issues that adversely impact the facility's ability to perform the designated functions described in your application. Satisfactory responses to these deficiencies are required prior to complete response resubmission.

Recommended response: Work with the facility to resolve all identified deficiencies and provide satisfactory responses to the FDA Form 483 prior to resubmission. Include the date(s) of the facility’s response(s) in the complete response.

Proprietary Name Resubmission Required

Severity: minor

The proposed proprietary name was found conditionally acceptable pending approval of the application in the current review cycle. It must be resubmitted when all other application deficiencies are addressed.

Recommended response: Resubmit the proposed proprietary name along with the complete response addressing all other deficiencies.

Comprehensive Safety Update Required

Severity: major

A comprehensive safety update is required as described at 21 CFR 314.50(d)(5)(vi)(b). This includes detailed descriptions of significant changes in safety profile, new safety data tabulations (combined with original data), comparison tables, separate tables for adverse events for other indications, retabulation of premature trial discontinuations, case report forms and narrative summaries for deaths/adverse event discontinuations/serious adverse events, and information on changes in common, less serious adverse events.

Recommended response: Provide a comprehensive safety update including all requested data analyses, tabulations, comparisons, case report forms, and narrative summaries as per 21 CFR 314.50(d)(5)(vi)(b).
