Interventions of Interest:
- Xanomeline tartrate/trospium chloride (KarXT, Karuna Therapeutics)
The independent appraisal committee voted that current evidence is not adequate to demonstrate superior net health benefits for KarXT compared to generically available aripiprazole.
If long-term data confirm KarXT’s benefits and lack of weight gain, it would achieve common thresholds for cost-effectiveness if priced between $16,000 to $20,000 per year.
Final Documents
ICER’s Chief Medical Officer, David Rind, MD stated:
“Schizophrenia is a serious mental illness that affects how a person thinks, feels, and behaves. Among the important side effects of current treatments is weight gain leading to metabolic syndrome. This, in turn, places patients at risk for cardiovascular events and death. KarXT has a novel mechanism of action and, at least in the short run, does not seem to cause weight gain. This may lead to major health benefits compared with existing treatments, however current evidence on benefits and harms is limited.”
