Summary

This document is a Complete Response letter from the FDA to Ocular Therapeutix, Inc. regarding their New Drug Application (NDA) 208742 for DEXTENZA (dexamethasone ophthalmic insert). The FDA has determined that the application cannot be approved in its current form due to deficiencies related to product quality/facilities inspection, prescribing information, proprietary name, and safety updates. The letter outlines specific issues and provides recommendations for addressing them.

Key points

  • Satisfactorily resolve deficiencies identified during the manufacturing facility inspection to comply with current good manufacturing practice regulations (21 CFR 210 and 211).
  • If revising labeling, review labeling review resources, use the SRPI checklist, and ensure the prescribing information conforms with format items in regulations and guidances.
  • Include updated content of labeling in structured product labeling (SPL) format (21 CFR 314.50(l)(1)(i)).
  • Resubmit the proposed proprietary name (DEXTENZA) when responding to the application facility inspection-related deficiencies.
  • Include a safety update with data from all nonclinical and clinical studies/trials of the product (21 CFR 314.50(d)(5)(vi)(b)).
  • Update visual inspection controls to include acceptable quality limits (AQL) and justification for the limits.
  • Provide a comprehensive list of manufacturing, equipment, and procedural changes and controls implemented since the previous re-submission.
  • Provide updated batch manufacturing instructions and any new production records supporting the NDA.

Cited reasons

  • Unresolved Manufacturing Facility Deficiencies
  • Proprietary Name Resubmission Timing
  • Safety Update Required
  • Labeling Content Update Required
  • Additional Manufacturing Control Recommendations
  • The application cannot be approved in its current form primarily due to unresolved manufacturing facility deficiencies related to cGMP compliance. Additionally, the agency requires a safety update and updated labeling content in SPL format upon resubmission, and clarification on the proprietary name resubmission timing. Several recommendations for manufacturing controls were also provided.

Recommended actions

  • Satisfactorily resolve deficiencies identified during the manufacturing facility inspection to comply with current good manufacturing practice regulations (21 CFR 210 and 211).
  • If revising labeling, review labeling review resources, use the SRPI checklist, and ensure the prescribing information conforms with format items in regulations and guidances.
  • Include updated content of labeling in structured product labeling (SPL) format (21 CFR 314.50(l)(1)(i)).
  • Resubmit the proposed proprietary name (DEXTENZA) when responding to the application facility inspection-related deficiencies.
  • Include a safety update with data from all nonclinical and clinical studies/trials of the product (21 CFR 314.50(d)(5)(vi)(b)).
  • Update visual inspection controls to include acceptable quality limits (AQL) and justification for the limits.
  • Provide a comprehensive list of manufacturing, equipment, and procedural changes and controls implemented since the previous re-submission.
  • Provide updated batch manufacturing instructions and any new production records supporting the NDA.

Deficiency summary

The application cannot be approved in its current form primarily due to unresolved manufacturing facility deficiencies related to cGMP compliance. Additionally, the agency requires a safety update and updated labeling content in SPL format upon resubmission, and clarification on the proprietary name resubmission timing. Several recommendations for manufacturing controls were also provided.

Findings

Unresolved Manufacturing Facility Deficiencies

Severity: critical

Satisfactory resolution of deficiencies identified during a recent inspection of the manufacturing facility (Ocular Therapeutix, Inc., FEI#3008477155) is required. The methods, facilities, and controls for manufacturing must comply with current good manufacturing practice regulations.

Recommended response: Address all deficiencies identified during the manufacturing facility inspection, ensuring full compliance with cGMP regulations (21 CFR 210 and 211). Provide comprehensive documentation of corrective and preventive actions (CAPA) and evidence of sustained compliance.

Cited: 21 CFR 210, 21 CFR 211

Proprietary Name Resubmission Timing

Severity: minor

The proposed proprietary name DEXTENZA was found acceptable pending approval of the application. The agency requests resubmission of the proposed proprietary name when responding to the application facility inspection-related deficiencies.

Recommended response: Resubmit the proposed proprietary name concurrently with the response to the manufacturing facility deficiencies to ensure proper administrative processing.

Safety Update Required

Severity: major

A comprehensive safety update, as described at 21 CFR 314.50(d)(5)(vi)(b), must be included when responding to the deficiencies. This update should encompass data from all nonclinical and clinical studies/trials of the product, regardless of indication, dosage form, or dose level.

Recommended response: Compile and submit a comprehensive safety update, including all relevant nonclinical and clinical data, in accordance with 21 CFR 314.50(d)(5)(vi)(b) as part of the resubmission.

Cited: 21 CFR 314.50(d)(5)(vi)(b)

Labeling Content Update Required

Severity: major

The agency reserves comment on the proposed labeling until the application is otherwise adequate. However, any revised labeling must include updated content of labeling as per 21 CFR 314.50(l)(1)(i) in structured product labeling (SPL) format.

Recommended response: Prepare updated content of labeling in SPL format, ensuring compliance with 21 CFR 314.50(l)(1)(i) and relevant guidance, to be submitted once manufacturing issues are resolved.

Cited: 21 CFR 314.50(l)(1)(i)

Additional Manufacturing Control Recommendations

Severity: info

Recommendations include updating visual inspection controls to include acceptable quality limits (AQL) with justification, and providing a comprehensive list of manufacturing, equipment, and procedural changes and controls since the previous resubmission, along with updated batch manufacturing instructions and new production records.

Recommended response: Address these recommendations to strengthen the application's quality control aspects, providing detailed documentation for AQLs and all manufacturing changes, even though they are not immediate approvability issues.
