Posted in Courses & Conferences,Industry News on 21st Jun 2021

New ONGENTYS® (opicapone) phase III study design released for first time at European Academy of Neurology (EAN) congress, alongside wealth of opicapone data
• Design of phase III study to investigate the efficacy of opicapone in early-stage Parkinson’s disease (PD) as an add-on to stable levodopa/dopa decarboxylase inhibitor (L-dopa/DDCI) therapy has been presented for the first time.1
• A design for an additional new study to evaluate the potential for opicapone as a first-line option to address ‘wearing off’ for patients on L-dopa/DDCI was also presented.2
• Designs for three further opicapone studies were also shared at EAN 2021, alongside new data from the real-world OPTIPARK study on the influence of age, disease duration and onset of motor fluctuations (MF) on opicapone treatment outcomes3-8


PORTO, Portugal, 18 June 2021 – The design for a new phase III, double-blind, randomised trial for opicapone has been presented for the first time at the European Academy of Neurology (EAN) congress. Around 50% of patients with PD experience some degree of motor complications within 2–5 years of starting L-dopa/DDCI therapy and almost all develop such symptoms after 10 years of L-dopa/DDCI therapy.9,10 Opicapone is a once-daily catechol-O-methyltransferase (COMT) inhibitor, approved in Europe for the treatment of end-of-dose motor fluctuations in adult PD patients on L-dopa/DDCI therapy.11 The EPSILON (Early Parkinson with L-dopa/DDCI and OpicapoNe) study will investigate the use of opicapone earlier in the treatment pathway, prior to the appearance of motor complications, over the course of 6 months, to explore its potential to enhance the benefit of L-dopa/DDCI in early-stage PD.1

The design for a new randomised, prospective, open-label exploratory trial, ADOPTION (eArly levodopa with Opicapone in Parkinson’s paTients with motOr fluctuatioNs), was also presented at the congress.2 As with EPSILON, the study will evaluate the potential for earlier opicapone use, this time as a first-line add-on treatment for patients on L-dopa/DDCI experiencing ‘wearing off’.2

Lead author for both study designs, Professor Joaquim Ferreira, commented:

We are pleased to share the designs for these new studies exploring the potential for opicapone as a first-line treatment for both early motor complications and early-stage Parkinson’s disease before motor complications have occurred. Previous clinical studies have demonstrated the efficacy of opicapone in the treatment of end-of-dose motor fluctuations so it will be interesting to see if this is reflected at different points in the treatment pathway. We look forward to sharing data from these studies as they become available.

Three further study designs will be presented at the congress; these studies have been developed to investigate the impact of opicapone on L-dopa pharmacokinetics at different L-dopa/carbidopa-optimised treatment regimens, PD-associated sleep disorders and motor fluctuation-associated pain, all in patients with end-of-dose motor fluctuations.3-5 In addition to this, a wealth of data will be shared from the OPTIPARK real-world study, revealing the impact of various factors, including age, disease duration and onset of MF, on the effectiveness of opicapone.6-8

Professor Soares da Silva, Director of Research & Development of Bial, shared his thoughts: “More than 10 million people worldwide are living with Parkinson’s disease,12 a condition that can have an enormous impact on quality of life. At Bial we are committed to improving the lives of patients with Parkinson’s through our medical research and ongoing support and resources. A key part of this is our dedication to new avenues of research for existing treatments. We are proud to be presenting designs for so many new opicapone studies at EAN 2021, as well as being able to share such a range of data from our previous trials.”

BIAL is presenting opicapone data from 22 abstracts at the EAN 2021 congress.

About ONGENTYS® (opicapone)

Opicapone is a once-daily, peripherally-acting, third-generation, highly-selective COMT inhibitor.11
Opicapone works by decreasing peripheral levodopa’s conversion rate into 3-O-methyldopa, thereby prolonging the duration of levodopa’s effect in reducing the OFF-time period of PD and extending the ON-time period.11
In June 2016, the European Commission authorised ONGENTYS® (opicapone) as an adjunct therapy to preparations of levodopa/DOPA decarboxylase inhibitors (DDCIs) in adult patients with PD and end-of-dose motor fluctuations who cannot be stabilised on those combinations.11 In Europe, opicapone is currently marketed in Germany, United Kingdom, Spain, Portugal, Italy and Switzerland.
BIAL entered into an exclusive licensing agreement with Neurocrine Biosciences, Inc. in February 2017 for the development and commercialisation of opicapone in the U.S. and Canada.
In November 2019, ONGENTYS® (opicapone) was approved by the regulatory authorities of South Korea and is commercialised by BIAL’s partner SK Chemicals Co., Ltd.
In April 2020, the U.S Food and Drug Administration (FDA) approved ONGENTYS® (opicapone) as an add-on treatment to levodopa/carbidopa in patients with Parkinson’s disease experiencing “off” episodes.
ONGENTYS® (opicapone) is marketed in Japan by BIAL’s partner Ono Pharmaceutical Co., Ltd., after approval of the Japanese authority in June 2020.
ONGENTYS® (opicapone) is also marketed in Finland since May 2021 by BIAL’s partner NordicInfu Care AB
