Gothenburg, Sweden, April 25th, 2023 – Dizlin Pharmaceuticals AB, a research-based pharmaceutical development company with focus on diseases of the central nervous system (CNS), today announces a patent approval in the USA

Dizlin Pharmaceuticals has secured a solid patent protection concerning the innovations of Infudopa SubC and Infudopa IntraV for the treatment of advanced Parkinson’s Disease (PD) in the USA – the biggest pharma market in the world. As announced earlier, Dizlin Pharmaceuticals also has patent protection for, among others, Europe, Mexico, and Japan (which is the second biggest PD market).

“This robust patent protection, which will expire in 2039, will give us many years at the market without generic entrance and this was exactly what we had hoped for”, says Björn Velin, CEO of Dizlin Pharmaceuticals. “We have now secured a solid patent protection in the most important markets in the world – USA, Europe, and Japan – and more approved patents are likely to arrive later this year.”

About Infudopa IntraV™
Infudopa IntraV™ (DIZ101) is a levodopa-carbidopa solution aimed to be administered intravenously using infusion pumps to inpatients who cannot receive oral administration of levodopa when being the subject of surgery with general anesthesia.

About Infudopa SubC™
Infudopa SubC™ (DIZ102) is a levodopa-carbidopa solution intended for outpatient treatment. Used with a portable twin pump enabling continuous mixing prior to infusion, Infudopa SubC™ is aimed as monotherapy for subjects who experience moderate to severe motor fluctuations when receiving oral administration of levodopa. When reaching the patient, Infudopa SubC™ displays a physiologically acceptable pH which also seems to optimize efficient levodopa uptake. The shelf life is 36 months in refrigerator and at least three months at room temperature, which would represent a significant logistic advantage for patients, e.g., when traveling.

About Parkinson’s disease
Parkinson´s disease (PD) is a serious neurodegenerative disease afflicting more patients than multiple sclerosis, amyotrophic lateral sclerosis, muscular dystrophy, and myasthenia gravis combined. Characterized by bradykinesia (poverty of motion), tremor, and muscular rigidity, and caused by degeneration of neurons using dopamine as transmitter, PD is a chronic and progressive condition, with a prevalence of 1% over the age of 60 and 3% of those over 75.

The company conducts research in collaboration with researchers at the University of Gothenburg and Linköping University in Sweden.

The company has developed a new patented method for treatment of advanced stages of Parkinson’s disease. Dizlin Pharmaceuticals has two products in late phase development stage.
