Metabolite Identification
Common NameBrexpiprazole
DescriptionBrexpiprazole, also known as rexulti, belongs to the class of organic compounds known as n-arylpiperazines. These are organic compounds containing a piperazine ring where the nitrogen ring atom carries an aryl group. Brexpiprazole is a very strong basic compound (based on its pKa). By contrast, brexpiprazole has a much higher affinity for the 5-HT1A receptor than aripiprazole as well as a much higher intrinsic activity. Phase III A new Phase III study was in the recruiting stage: "Study of the Safety and Efficacy of Two Fixed Doses of OPC-34712 as Adjunctive Therapy in the Treatment of Adults With Major Depressive Disorder (the Polaris Trial)". It has been designed to provide improved efficacy and tolerability (e.g., less akathisia, restlessness and/or insomnia) over established adjunctive treatments for major depressive disorder (MDD). Lundbeck gave Otsuka an upfront payment of $200 million, and the deal includes development, regulatory and sales payments, for a potential total of $1.8 billion. This compound has been identified in human blood as reported by (PMID: 31557052 ). Brexpiprazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Brexpiprazole is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
