FDA validation of the submission dossier prior to the
The sNDA submission is based on previously disclosed results, including data from the two clinical phase III trials (#071 flexible dose trial n=416[i] and #072 fixed-dose trial (n=553[ii])), and the clinical phase II (#061 flexible dose trial n=321[iii]). All three trials investigated the treatment of PTSD in adults treated with brexpiprazole in combination with sertraline versus sertraline plus placebo.
The primary endpoint for all three trials was the change from Week 1 to Week 10 in the Clinician-Administered PTSD Scale (CAPS-5) total score for brexpiprazole and sertraline combination therapy versus sertraline plus placebo at Week 10 in patients diagnosed with PTSD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
- Trial #071 and trial #061 demonstrated that the combination treatment of brexpiprazole and sertraline was superior to treatment with sertraline plus placebo
- Although trial #072 did not demonstrate superiority of the combination treatment of brexpiprazole and sertraline compared to treatment with sertraline plus placebo, the change from baseline observed in the combination group (brexpiprazole and sertraline) was consistent with the reductions observed in trials #071 and #061
- Brexpiprazole in combination with sertraline was observed to be generally well-tolerated and the safety results of the three trials were consistent with the known safety profile of brexpiprazole
Lundbeck and Otsuka intend to present detailed data from all three trials at the
About post-traumatic stress disorder (PTSD)
PTSD is a psychiatric disorder that may occur in people who have experienced, or witnessed, a traumatic event, series of events or set of circumstances. An individual may experience this as emotionally or physically harmful or life-threatening and may affect mental, physical, social, and/or spiritual well-being. Examples include natural disasters, serious accidents, terrorist acts, war/combat, rape/sexual assault, historical trauma, intimate partner violence and bullying[iv].
PTSD can occur in people, of any ethnicity, nationality, or culture, and at any age. It affects more than 13 million people in the
Symptoms of PTSD are generally grouped into four types: intrusive memories, avoidance, negative changes in thinking and mood, and changes in physical and emotional reactions. Symptoms can vary over time or vary from person to person[vi]. Symptoms usually begin within 3 months of the traumatic incident, but they sometimes emerge later. To meet the criteria for PTSD, symptoms must last longer than 1 month, and they must be severe enough to interfere with aspects of daily life, such as relationships or work[vii].
About brexpiprazole
Brexpiprazole was approved in the
Brexpiprazole was discovered by Otsuka and is being co-developed by Otsuka and Lundbeck. The mechanism of action of brexpiprazole is unknown, however the efficacy of brexpiprazole may be mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, antagonist activity at serotonin 5-HT2A receptors, as well as antagonism of alpha 1B/2C receptors.
