The quest to treat post-traumatic stress disorder (PTSD) with new medication faces an unexpected hurdle. Otsuka America Pharmaceutical, Inc., and H. Lundbeck A/S, major players in the pharmaceutical sector, find themselves reevaluating their strategy after the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) regarding their supplemental New Drug Application (sNDA). The sNDA sought approval for using a combination of REXULTI® (brexpiprazole) and sertraline to treat adults with PTSD. The decision stirs conversation about the potential pathways to explore in reaching an effective treatment for this prevalent mental health condition.
Regulatory Roadblock
The FDA stated after reviewing the sNDA that it could not approve it because the application failed to present substantial evidence of effectiveness. Despite relying on data from three randomized clinical trials, the FDA maintained that not all studies contributed to sufficient evidence for approval. Earlier in July, the Psychopharmacologic Drugs Advisory Committee had also expressed skepticism during their vote, with a 1-10 tally against the efficacy of brexpiprazole in combination with sertraline for treating PTSD.
Industry Reactions and Next Steps
Otsuka and Lundbeck remain optimistic about brexpiprazole’s potential in treating PTSD, emphasizing addressing unmet needs in psychiatric care. The companies plan to review the FDA’s feedback thoroughly to establish their future course of action. As underscored by John Kraus, M.D., Ph.D., they see value in their medication combination and are committed to advancing care for those grappling with PTSD.
– Brexpiprazole has approval for other conditions like major depressive disorder and schizophrenia.
– The CRL highlights the necessity for more robust clinical trial data to support its efficacy in PTSD treatment.
– Otsuka and Lundbeck’s response underlines continued dedication to pursuing innovative solutions for mental health challenges despite regulatory setbacks.
PTSD represents a significant mental health challenge, affecting around 5% of the U.S. population annually. The disorder results from traumatic events and manifests through various symptoms, complicating daily life. Standard treatment involves psychotherapy, but medication becomes critical when therapy is unavailable or patients prefer pharmaceutical interventions. The therapeutic landscape for PTSD continually evolves as researchers and developers strive to provide effective solutions.
Moving ahead, Otsuka and Lundbeck’s commitment will entail further clinical trials to gather the substantial evidence required for FDA approval, ensuring potential treatment regimens meet the highest efficacy standards. This pursuit reflects ongoing strides in mental health research, crucial for addressing the increasing burden of PTSD on individuals and society. Stakeholders and patients alike await developments with cautious optimism, recognizing the complexities and time investment needed to bring new therapeutic options to fruition.
