The First New Class of Antipsychotic Drugs in 70 Years Offers Hope for Millions but Faces Pricing Challenges
In a significant advancement for the treatment of schizophrenia, the U.S. Food and Drug Administration (FDA) has approved Bristol Myers Squibb’s (BMY) new drug, Cobenfy. This marks the first time in over seven decades that a novel class of medication has been developed to address the debilitating mental disorder, offering a new lifeline to the nearly 3 million adults in the United States living with schizophrenia. The company plans to make the twice-daily pill available by late October, with a monthly price tag of $1,850, or $22,500 annually, before insurance and rebates.
A New Hope for Schizophrenia Treatment
Schizophrenia, a chronic mental disorder that distorts a person’s thoughts, feelings, and behavior, can manifest through symptoms such as paranoia, delusions, hallucinations, and significant changes in emotion and behavior. These symptoms often lead to severe disruptions in daily life, making it difficult for individuals to work, socialize, or manage basic tasks. Typically diagnosed in late teens to early adulthood, the condition has long been in need of more effective and tolerable treatment options.
Cobenfy’s approval is seen as a major breakthrough, particularly given that only about 1.6 million schizophrenia patients in the U.S. receive treatment, and a staggering 75% of those patients discontinue their medication within the first 18 months due to inefficacy or intolerable side effects. Existing antipsychotic drugs work by directly blocking dopamine receptors in the brain, which, while effective for some, come with a host of serious side effects, including weight gain, excessive fatigue, and involuntary movements. These adverse effects often lead to patients abandoning their treatment, further complicating their condition.
A New Mechanism of Action
Cobenfy represents a departure from traditional antipsychotic treatments. Rather than directly blocking dopamine receptors, Cobenfy utilizes a dual-action mechanism involving two components: xanomeline and trospium. Xanomeline activates specific muscarinic receptors in the brain, indirectly reducing dopamine activity without the severe side effects associated with conventional antipsychotics. Trospium, on the other hand, mitigates the gastrointestinal side effects commonly linked to xanomeline, such as nausea, vomiting, and diarrhea, making the treatment more tolerable for patients.
Dr. Samit Hirawat, Chief Medical Officer of Bristol Myers Squibb, emphasized that Cobenfy’s innovative approach could significantly improve the lives of those who have struggled to find effective and manageable treatments. “The majority of these patients have already cycled through one or two of these products,” Hirawat said. “So the enthusiasm that we’re hearing from physicians is the opportunity to have a patient go onto treatment without seeing the side effects but also getting unprecedented efficacy.”
Market Potential and Economic Considerations
Cobenfy’s approval comes at a critical time for Bristol Myers Squibb, which is facing the impending loss of revenue from top-selling drugs that are approaching patent expiration. The drug, which was acquired through Bristol Myers Squibb’s $14 billion purchase of Karuna Therapeutics, is anticipated to be a significant long-term revenue driver for the company. While analysts at Guggenheim have predicted that Cobenfy could become a multi-billion dollar product, they also noted that its launch may be slow, meaning it might not substantially impact the company’s revenue until 2026 or later.
However, the high cost of Cobenfy could be a barrier to its widespread adoption. At $1,850 per month, the drug is priced comparably to other branded schizophrenia treatments, but significantly higher than generic options, such as the generic version of Abilify, which can be as low as $16 for a month’s supply. While Bristol Myers Squibb has assured that most patients, particularly those on Medicare and Medicaid, will face minimal out-of-pocket costs, the company’s Chief Commercialization Officer, Adam Lenkowsky, acknowledged that the drug’s price might limit its initial use to patients who have failed other treatments.
Future Prospects for Cobenfy
The FDA’s approval of Cobenfy is based on data from three clinical trials that demonstrated its efficacy in reducing schizophrenia symptoms compared to a placebo, as well as two longer-term studies assessing its safety and tolerability over a year. While the initial approval is for schizophrenia, Bristol Myers Squibb has ambitious plans for Cobenfy, with ongoing research into its potential applications for other conditions such as Alzheimer’s disease, bipolar mania, and autism-related irritability.
Andrew Miller, founder and former president of research and development at Karuna Therapeutics, now an advisor to Bristol Myers Squibb, expressed optimism about the long-term impact of Cobenfy. “I think there’s potentially a really transformational moment in how we treat and talk about schizophrenia,” Miller said. “The most important moment is going to be five or ten years from now when we look back and say we’ve actually made a difference.”
As the healthcare community awaits the broader implications of Cobenfy’s introduction, its approval represents a pivotal moment in the treatment of schizophrenia, offering renewed hope to millions of patients and their families.
