Summary

The FDA issued a Complete Response letter for NDA 214429 for Fexinidazole tablets, indicating that the application cannot be approved in its current form due to deficiencies primarily related to product labeling and the need for an updated safety profile.

Key points

  • Submit draft labeling that addresses the FDA's proposed revisions communicated via email on November 4, 2020.
  • Use the SRPI checklist to correct any formatting errors in the labeling to ensure conformance with regulations and guidances.
  • Submit updated content of labeling in Structured Product Labeling (SPL) format as described at FDA.gov, per 21 CFR 314.50(l)(1)(i).

  • Prescribing Information (PI) Formatting and Content Deficiencies
  • Carton and Container Labeling Inconsistencies

Findings

Failure to Submit Revised Labeling and Reach Agreement

Severity: major

The applicant notified the FDA on November 9, 2020, that they would not be able to submit revised labeling during the current review cycle, preventing an agreement on product labeling.

Recommended response: Submit draft labeling that addresses the FDA's proposed revisions communicated via email on November 4, 2020.

Prescribing Information (PI) Formatting and Content Deficiencies

Severity: major

The proposed Prescribing Information (PI) does not conform to content and format regulations. Specific issues include formatting errors, lack of updated content of labeling in Structured Product Labeling (SPL) format, and non-conformance with 21 CFR 201.56(a), (d) and 201.57.

Recommended response: Correct formatting errors using the SRPI checklist, submit updated content of labeling in SPL format, and ensure PI conforms to 21 CFR 201.56(a), (d) and 201.57. Provide a highlighted/marked-up copy and a clean Word version.

Cited: 21 CFR 314.50(l)(1)(i), 21 CFR 201.56(a), 21 CFR 201.56(d), 21 CFR 201.57

Carton and Container Labeling Inconsistencies

Severity: major

The submitted carton and container labeling is not identical to previously submitted versions (carton/wallet labeling submitted August 18, 2020, and container/blistercards labeling submitted September 2, 2020).

Recommended response: Submit carton and container labeling identical to the versions submitted on August 18, 2020, and September 2, 2020.

Incomplete Safety Update

Severity: major

The safety update provided is incomplete and does not fully comply with 21 CFR 314.50(d)(5)(vi)(b). Specific missing elements include detailed changes in safety profile, new safety data presentation, combined tabulations, comparison tables, separate tables for other indications, retabulation of premature discontinuations, case report forms/narratives for deaths/SAEs, information on incidence of common AEs, updated exposure information, worldwide experience summary, and English translations of foreign labeling.

Recommended response: Provide a comprehensive safety update as per 21 CFR 314.50(d)(5)(vi)(b), including all specified data elements for nonclinical and clinical studies, worldwide experience, and foreign labeling translations.
