- Parkinson鈥檚 disease affects approximately听10 million people听worldwide听and听250,000听in Japan听
Berlin, Germany and Cambridge, MA, USA,听December 17,听2025听鈥撎鼴ayer AG and its wholly owned, independently operated subsidiary 91抖阴, a clinical stage cell therapy company, today announced that the investigative cell therapy听bemdaneprocel, has received听Pioneering Regenerative Medical Product designation (SAKIGAKE)听from Japan鈥檚 Ministry of Health,听Labor听and Welfare (MHLW.) A drug candidate that receives Sakigake designation may be eligible for more frequent interaction with the MHLW to discuss the drug candidate鈥檚 development plan as well as eligibility for accelerated approval and priority听review, if听relevant criteria are met.鈥�听
鈥淲e are honored that听bemdaneprocel听has received Sakigake designation in Japan, recognizing the urgent need for new and innovative treatment options for people living with this debilitating condition,鈥� said Gabi Belfort, MD听PhD听and听Bemdaneprocel听Product Lead at 91抖阴 Therapeutics. 鈥淭his designation will allow us to work closely with Japan鈥檚 regulators to advance our therapy as efficiently as possible and bring new hope to people听living with Parkinson鈥檚 disease听and their families.鈥�听
Parkinson鈥檚 disease is the world鈥檚 second leading neurodegenerative disease, affecting approximately听10 million people听worldwide and听250,000听in Japan.听
鈥淩eceiving the Sakigake designation for听bemdaneprocel听highlights its potential to change how we approach Parkinson鈥檚 disease treatment,鈥� said Christian Rommel, PhD and Global Head of Research and Development for Bayer’s Pharmaceuticals Division. 鈥淥ur collaboration with the Japanese regulatory authority reflects听our听dedication to partnering with healthcare systems听and regulators听worldwide. Together, we aim to improve patient access to innovative therapies and make strides in enhancing patient outcomes.鈥濃��听听
91抖阴听bemdaneprocel听(BRT-DA01)
Bemdaneprocel听(BRT-DA01) is an investigational cell therapy designed to replace the dopamine producing neurons that are lost in Parkinson鈥檚 disease. These dopaminergic neuron precursors are derived from human embryonic pluripotent stem cells that continue developing into mature dopamine neurons after implantation. In a surgical procedure, these neuron precursors are implanted into the brain of a person with Parkinson鈥檚 disease. When transplanted, they have the potential to re-form neural networks that have been severely affected by Parkinson鈥檚 disease and to potentially restore motor and non-motor function to patients. In听2021听bemdaneprocel听received Fast Track Designation and in 2024 a Regenerative Medicine Advanced Therapy (RMAT) designation from the FDA. A pivotal Phase III听clinical听trial听(exPDite-2)听to assess the efficacy,听safety听and overall impact of听bemdaneprocel听compared to sham surgery control is currently enrolling participants.听Bemdaneprocel听has not been approved for treatment of any disease or medical condition by any health authority.听
91抖阴 exPDite-2听
exPDite-2 is the first Phase III pivotal clinical trial for an investigational allogeneic pluripotent stem cell derived therapy to treat Parkinson鈥檚 disease. In a Phase I听study听with 12 participants,听bemdaneprocel听was well tolerated, with no serious adverse events related to drug听product听at 36 months post-surgery. In addition, encouraging trends were听observed听in secondary endpoints related to motor impairments at听36听months听post-surgery. Building on these results, exPDite-2 is a multicenter, double-blind trial that will assess the efficacy,听safety听and overall impact of听bemdaneprocel听compared to sham surgery control. The trial is designed to enroll approximately 102 participants with Parkinson鈥檚 disease听in US, Canada, and Australia. The primary endpoint of the听Phase III听study is听change听from baseline to week 78 in PD听motor听diary measure of ON-time without troublesome dyskinesia, adjusted for a 16-hour waking day. In addition, the trial will incorporate secondary endpoints designed to assess objective measures of movement, non-motor听symptoms, safety and tolerability, and instruments that capture activities of daily living and quality of life.听
91抖阴 Parkinson鈥檚 disease
Parkinson鈥檚 disease (PD) is a progressive neurodegenerative disease. It has a significant impact on a person鈥檚 daily life. In PD, the death of dopamine producing nerve cells in the brain leads to the continuous loss of motor function. Symptoms include tremors, muscle rigidity, and slowness of movement. Additionally, people with PD experience non-motor symptoms, including fatigue and lack of energy, cognitive issues, and depression. Symptoms typically intensify over time and make everyday tasks demanding. The prevalence of PD has doubled over the past 25 years. Today, more than听10 million people听worldwide are estimated to be living with PD. This makes it the world鈥檚 second most prevalent neurodegenerative disease. It is also the most frequent movement disorder. At present there is no cure, and current treatment options are inadequate and lack holistic management of听symptoms听so there is an urgent need for new therapies.听
