12.11.2021 13:36:13 CET | Business Wire | Press release
Kyowa Kirin Co., Ltd. (TSE:4151, President and CEO: Masashi Miyamoto, “Kyowa Kirin”) today announced that following a re-examination procedure the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) issued a negative opinion for istradefylline as an add-on treatment to levodopa (L-Dopa) based regimens in adults living with Parkinson’s, experiencing end-of-dose motor fluctuations. Parkinson’s is a chronic, progressive neurodegenerative condition that affects small regions in the brain that control movement, balance and posture.1 It is the fastest growing neurodegenerative disorder in the world.2
“We are disappointed by the CHMP opinion. We will take time to assess our plans for istradefylline in EMEA,” said Tomohiro Sudo, Executive Officer, Head of Global Product Strategy Department at Kyowa Kirin. “We appreciate the collaboration we have had with all stakeholders and applaud the Parkinson’s community for their commitment to supporting people living with this chronic, debilitating condition.”
The Kyowa Kirin Group companies strive to contribute to the health and well-being of people around the world by creating new value through the pursuit of advances in life sciences and technologies. The company is committed to bringing our innovative therapies to patients.
About istradefylline
Istradefylline was developed as a novel, first-in-class non-dopaminergic, adenosine A2A receptor antagonist that reduces ‘OFF’ time in people living with Parkinson’s through selective targeting of adenosine A2A receptors in the basal ganglia. Whilst dopaminergic treatment targets the dopamine receptors in the direct and indirect pathways to facilitate movement, istradefylline, as an add-on to L-Dopa, reduces the activity of the indirect pathway which suppresses movement.3,4 Consequently, it helps restore the balance within the basal ganglia.1,2
About Parkinson’s and ‘OFF’ episodes
There are an estimated 10 million people in the world currently living with Parkinson’s.5 Although it is classically characterised by motor symptoms (symptoms involving movement), people living with the condition also experience a large range of non-motor symptoms, which add to the complexity of living with the condition.5 Although Parkinson’s is not life threatening there is currently no cure.1 Over time symptoms progress and can be unpredictable, imposing a significant impact on daily life.1 This impact can extend to caregivers, friends and family, whose own wellbeing and quality of life can deteriorate as a result.6
‘OFF’ episodes is used to describe the return of Parkinson’s symptoms, also known as ‘OFF’ symptoms, and can be triggered by a variety of phenomena, including:7
- Delayed onset of response to medication
- Reduced duration of benefit from a medication
- Reduced or no efficacy of a dose of medication

Dompé Doses First Patient in Phase 3 Study of Cenegermin-bkbj in NAION14.7.2026 14:00:00 CEST | Press release
Non-arteritic anterior ischemic optic neuropathy (NAION) is a loss of blood flow to the optic nerve which causes spontaneous and rapid vision loss, for which there are currently no FDA-approved treatments. Given the substantial unmet need for effective treatments in NAION, in October 2025, Dompé was awarded a Commissioner’s National Priority Review Voucher (CNPV) by the US FDA to accelerate a potential Biologics License Application for intranasal nerve growth factor (NGF) in NAION. Dompé, a biopharmaceutical company with operations in Italy and the US, announced the first patient has been enrolled in a Phase 3 study of cenegermin-bkbj for the treatment of non-arteritic anterior ischemic neuropathy (NAION). Involving more than 130 centers globally, the Phase 3 trial, “Galassia-NAION-301” is a multicenter, double-blind study comparing cenegermin-bkbj against placebo in improving vision loss caused by NAION. “Our NGF R&D program continues to accelerate with our third clinical study of 202
