New data reinforces Ipsen’s commitment to bringing solutions and addressing care gaps in neurological diseases at TOXINS

• 14 abstracts will be presented across a range of neurological conditions including post‑stroke spasticity, cervical dystonia, blepharospasm and other movement disorders
• Interim data from the ongoing EPITOME trial¹ showed that 45.7% of stroke survivors with paresis developed post-stroke spasticity within 1 year
• <1% of stroke survivors receive BoNT-A treatment for spasticity in routine practice²

PARIS, FRANCE, 14 JANUARY 2026 - Ipsen (Euronext: IPN; ADR: IPSEY) announced today the presentation of 14 across multiple neurological conditions at the TOXINS 2026 conference (14-17 January) in Madrid, Spain. Data presented highlighted the depth and diversity of evidence across multiple movement disorders — including post‑stroke spasticity, cervical dystonia and blepharospasm, adding to the available evidence of Dysport®(abobotulinumtoxinA) in patient care – alongside new indications under evaluation.

An interim analysis from the ongoing EPITOME study will be presented. EPITOME is a multi-country epidemiologic study following adults aged 18–85 after their first stroke, to better understand how often post-stroke spasticity (PSS) occurs and to better improve early identification. The study focuses on a Post-stroke Spasticity Monitoring Questionnaire, a remote monitoring tool designed to help clinicians detect early signs of spasticity.

PSS can develop following a stroke and often goes undiagnosed, delaying treatment and limiting recovery. Remote monitoring can help clinicians act sooner, improving the potential for swift rehabilitation and better quality of life for patients. In this interim analysis, 45.7% of stroke survivors with paresis developed spasticity within 1 year of their stroke vs previously documented 39.5%,³ reinforcing the value of monitoring within this period. Previously published real-world evidence and quality of life insights reinforce the existing care gap, with <1% of stroke survivors receiving BoNT-A treatment for spasticity in routine practice.²

“We are proud to present this breadth of data which underscores our mission to bring solutions and address care gaps for people living with a broad range of neurological conditions,” said Sandra Silvestri, MD, PhD, Executive Vice President, Chief Medical Officer, Ipsen. “The EPITOME study is one example of this, focused on providing a standardized and best-practice follow-up to ensure people living after a stroke receive the care they deserve.”

About Dysport

Dysport® (abobotulinumtoxinA) is an injectable form of a botulinum neurotoxin type A (BoNT-A) product, which is a substance derived from Clostridium bacteria producing BoNT-A that inhibits the effective transmission of nerve impulses and thereby reduces muscular contractions. It is supplied as a lyophilized powder. AbobotulinumtoxinA has marketing authorization in approximately 90 countries, more than 30 years of clinical experience and >18 million treatment years of patient experience.
The detailed recommendations for the use of Dysport are described in the Summary of Product Characteristics (SmPC) for Dysport (300 units) Powder and Dysport (500 units) Powder, and the U.S. Prescribing Information (PI).

NOTE: Dysport® labels and approved indications may vary from country to country.

Disclaimers and/or forward-looking statements
The forward-looking statements, objectives and targets contained herein are based on Ipsen’s management strategy, current views and assumptions. Such statements involve known and unknown risks and uncertainties that may cause actual results, performance or events to differ materially from those anticipated herein. All of the above risks could affect Ipsen’s future ability to achieve its financial targets, which were set assuming reasonable macroeconomic conditions based on the information available today. Use of the words ‘believes’, ‘anticipates’ and ‘expects’ and similar expressions are intended to identify forward-looking statements, including Ipsen’s expectations regarding future events, including regulatory filings and determinations. Moreover, the targets described in this document were prepared without taking into account external-growth assumptions and potential future acquisitions, which may alter these parameters. These objectives are based on data and assumptions regarded as reasonable by Ipsen. These targets depend on conditions or facts likely to happen in the future, and not exclusively on historical data. Actual results may depart significantly from these targets given the occurrence of certain risks and uncertainties, notably the fact that a promising medicine in early development phase or clinical trial may end up never being launched on the market or reaching its commercial targets, notably for regulatory or competition reasons. Ipsen must face or might face competition from generic medicine that might translate into a loss of market share. Furthermore, the research and development process involves several stages each of which involves the substantial risk that Ipsen may fail to achieve its objectives and be forced to abandon its efforts with regards to a medicine in which it has invested significant sums. Therefore, Ipsen cannot be certain that favorable results obtained during preclinical trials will be confirmed subsequently during clinical trials, or that the results of clinical trials will be sufficient to demonstrate the safe and effective nature of the medicine concerned. There can be no guarantees a medicine will receive the necessary regulatory approvals or that the medicine will prove to be commercially successful. If underlying assumptions prove inaccurate or risks or uncertainties materialize, actual results may differ materially from those set forth in the forward-looking statements. Other risks and uncertainties include but are not limited to, general industry conditions and competition; general economic factors, including interest rate and currency exchange rate fluctuations; the impact of pharmaceutical industry regulation and healthcare legislation and risks arising from unexpected regulatory or political changes such as changes in tax regulation and regulations on trade and tariffs, such as protectionist measures, especially in the United States; global trends toward healthcare cost containment; technological advances, new medicine and patents attained by competitors; challenges inherent in new-medicine development, including obtaining regulatory approval; Ipsen’s ability to accurately predict future market conditions; manufacturing difficulties or delays; financial instability of international economies and sovereign risk; dependence on the effectiveness of Ipsen’s patents and other protections for innovative medicines; and the exposure to litigation, including patent litigation, and/or regulatory actions. Ipsen also depends on third parties to develop and market some of its medicines which could potentially generate substantial royalties; these partners could behave in such ways which could cause damage to Ipsen’s activities and financial results. Ipsen cannot be certain that its partners will fulfil their obligations. It might be unable to obtain any benefit from those agreements. A default by any of Ipsen’s partners could generate lower revenues than expected. Such situations could have a negative impact on Ipsen’s business, financial position or performance. Ipsen expressly disclaims any obligation or undertaking to update or revise any forward-looking statements, targets or estimates contained in this press release to reflect any change in events, conditions, assumptions or circumstances on which any such statements are based, unless so required by applicable law. Ipsen’s business is subject to the risk factors outlined in its registration documents filed with the French Autorité des Marchés Financiers.
