FDA Approves Mezofy (aripiprazole) Oral Film for the Treatment of Schizophrenia


In continuation of my update on Aripiprazole




CMG Pharmaceuticals, an affiliate of Cha Biotech, announced on the 16th that it had received product approval for the schizophrenia treatment drug Mezofy (formerly Depibzo) from the U.S. Food and Drug Administration (FDA).

Mezofy is an oral film-type schizophrenia treatment drug (ingredient name: aripiprazole) developed by CMG Pharmaceuticals. Patients with mental illnesses including schizophrenia often refuse or spit out medication, but the film-type drug can be taken without water and easily dissolves in the mouth, solving this problem.

CMG Pharmaceuticals first applied for FDA approval in December 2019. At that time, CMG Pharmaceuticals was the world’s first film-type schizophrenia treatment company to knock on the FDA’s door. However, the supplementary inspection was delayed due to problems with overseas raw material factories and the impact of the COVID-19 pandemic.

Meanwhile, Opipza, aripiprazole film treatment from China's LP Pharma, received FDA approval in July of last year. CMG Pharmaceuticals then reapplied for product approval in October of last year and received marketing approval.

Mezofy is the fourth product from a domestic pharmaceutical company to receive FDA approval for an improved new drug. An improved new drug is not simply a copy of a new drug whose patent has expired, but rather an improvement in the dosage method by changing the efficacy or formulation. Unlike simple generic drugs, it is protected separately by a patent.

The company explained, “The price of improved new drugs is set higher than that of generic drugs, and they can be marketed and prescribed under the product name rather than the ingredient name, which is advantageous in increasing awareness in the market.”


CMG Pharmaceuticals expects Mezofy to be launched in the US in the first half of 2026. According to Data Monitor, a US market research and analysis firm, the US schizophrenia treatment market is the largest in the world, at 12 trillion won.

The company predicted that the market for Mezofy would expand to over KRW 22 trillion when its indications are expanded to include bipolar disorder, major depressive disorder, autism spectrum disorder, and Tourette's disorder.

The company said, “We plan to complete the selection of a local distribution partner in the U.S. by the second half of this year,” and “We will work with our distribution partners to establish a competitive drug pricing strategy.”

CMG Pharmaceuticals has set a goal of achieving annual sales of over 100 billion won within five years of entering the U.S. market. CMG Pharmaceuticals CEO Lee Ju-hyung said, “After proving the excellence of Mezofy in the U.S. market, we will advance into other overseas markets.”

At the time of the initial application for product approval, the product name was Depipzo. The company explained that in collaboration with the global pharmaceutical branding specialist Brand Institute, it decided on Mezofy as a name that is easier to remember and less likely to cause prescription errors.

FDA Approves Atzumi (dihydroergotamine) Nasal Powder for the Acute Treatment of Migraine

Shin Nippon Biomedical Laboratories, Ltd. (TSE:2395),  announced  the U.S. Food and Drug Administration (FDA) approval of    New Drug Application (NDA) for Atzumi™(dihydroergotamine (DHE)) nasal powder for the acute treatment of migraine with or without aura in adults. Atzumi was previously known as STS101.

 




Migraine is a neurological disorder that is thought to be the result of temporary changes in the chemicals, nerves and blood vessels in the brain, with symptoms that are often incapacitating. According to the American Migraine Foundation, approximately 40 million Americans live with migraine. It is the second leading cause of disability worldwide in terms of time lost to disability and most common cause of disability among young women.

"The approval of Atzumi is a milestone to celebrate, providing a new option for the acute treatment of migraine combining long-proven benefits of DHE with a patient-friendly and easy-to-use delivery system developed based on SNBL's novel intranasal drug delivery platform technology," said Dr. Ryoichi Nagata, President and CEO of Satsuma. "We believe that Atzumi will contribute to improving the quality of life of patients struggling for relief from these highly disabling problems."

"DHE plays a unique clinical role in the acute treatment of migraine, providing patients long lasting effects and the unique ability to provide benefit even when taken late in a migraine attack. The convenience of Atzumi, the only DHE nasal powder, will offer patients ease of use combined with the important known DHE clinical advantages", said Dr. Stewart J. Tepper, M.D., Vice President of the New England Institute for Neurology and Headache in Stamford, Connecticut.

About Atzumi

Atzumi is a proprietary drug device product incorporating both Satsuma's advanced nasal powder formulation of dihydroergotamine (DHE) administered via its unique nasal delivery device. The product is designed to provide patients an easy-to-use and easy-to-carry treatment option.

The FDA approval for Atzumi is based on two clinical studies (Phase 1 PK trial and ASCEND Phase 3 open-label, long-term safety trial), which demonstrated fast absorption, rapid achievement of high DHE plasma concentrations, and sustained DHE plasma levels over time as well as safety and tolerability in subjects with migraine.

About Dihydroergotamine (DHE)

Since its approval in 1946, DHE has long been recommended in published migraine treatment guidelines as a first-line acute treatment option for migraine and has significant advantages versus other anti-migraine treatments for many patients. However, disadvantages of current DHE liquid nasal spray and injectable products, including invasive and burdensome administration and/or sub-optimal clinical performance, have limited the widespread use of DHE.
