Complete Response Letter NDA 505b1 220049 (Aug 18, 2025)

The FDA has issued a Complete Response Letter (CRL) for NDA 220049 for vatiquinone, indicating that the application is not ready for approval in its current form. The agency found that the nominally significant findings on exploratory endpoints (Upright Stability Subscale and Modified Fatigue Impact Scale) were not statistically robust or persuasive enough to establish effectiveness, especially given negative results on primary and key secondary endpoints. Concerns were raised regarding statistical observations, handling of missing data, baseline imbalances, and the interpretability of certain outcome assessments. Real-world evidence and biomarker data submitted as confirmatory evidence were deemed insufficient to serve as such without a positive, adequate, and well-controlled study. The FDA requires a new positive, adequate, and well-controlled study to establish effectiveness, suggests a specific study design, and outlines deficiencies related to nonclinical/product quality, labeling, proprietary name, and a comprehensive safety update for any resubmission.

Complete Response Letter BLA 761211 (Aug 6, 2025)

The FDA issued a Complete Response Letter (CRL) for Biologics License Application (BLA) 761211 for AEB1102, indicating that the effectiveness of the drug has not been established for traditional approval. While the drug showed a statistically significant reduction in plasma arginine levels, it failed to meet key secondary clinical endpoints. The FDA suggests that plasma arginine may be a reasonably likely surrogate endpoint for accelerated approval, provided a confirmatory trial is conducted. The letter outlines numerous deficiencies related to clinical efficacy, safety data updates, labeling, proprietary name resubmission, and specific clinical and clinical pharmacology data requirements, including trials for pediatric patients and subcutaneous administration.

The FDA has identified significant deficiencies in New Drug Application (NDA) 215244 for elamipretide, concluding that its effectiveness has not been established for traditional approval due to a lack of superiority over placebo in clinical trials (SPIBA-201 Part 1 & 2, SPIBA-001) and concerns regarding bias in endpoint measurements. The proposed surrogate endpoints (LVSV, MLCL:CL ratio, acylcarnitines) are also deemed insufficient for accelerated approval due to various limitations. The FDA suggests exploring muscle strength of knee extensors as a potential intermediate clinical endpoint for accelerated approval, contingent on demonstrating its predictive clinical benefit and proposing a confirmatory postmarketing trial. Additionally, the applicant must resolve facility inspection deficiencies, and address labeling and proprietary name issues.

The FDA has reviewed a New Drug Application (NDA 219045) for a naloxone HCl, 4 mg, nasal spray. While the product's efficacy is considered comparable to Narcan, significant safety concerns exist due to its higher systemic exposure, which is greater than Narcan. This higher exposure poses an increased risk of precipitated opioid withdrawal, especially in opioid-dependent individuals and in a nonprescription setting without healthcare guidance. The submitted safety data is deemed inadequate, and communicating this risk effectively on a Drug Facts Label (DFL) is challenging. The FDA recommends either product reformulation to achieve lower systemic exposure or conducting further studies to establish the safety of the current higher-exposure formulation for nonprescription use, along with potential labeling modifications. A comprehensive safety update is also required.
