Lundbeck Provides Update On The Development Program For Desmoteplase

* The first of two phase III clinical studies (DIAS-3) in patients with acute ischaemic stroke treated in the time-window 3-9 hours after stroke onset did not meet the primary endpoint
* When analysing only the patients fulfilling all protocol requirements (per protocol population) desmoteplase showed an effect relative to placebo
* The study demonstrated an excellent tolerability profile of desmoteplase
* As a consequence of the results the further development plan is under consideration

Valby, Denmark, 27 June 2014 - H. Lundbeck A/S (Lundbeck) today announced the initial headline conclusions from DIAS-3, the first of two phase III clinical trials of desmoteplase for the treatment of adult patients with acute ischaemic stroke.

The study did not meet the primary endpoint, i.e. the proportion of patients with a favourable outcome of modified Rankin Scale (mRS) score 0-2 at Day 90 was not statistically different between patients treated with desmoteplase (51.3%) and patients in the placebo control group (49.8%).

The DIAS-3 study confirmed the favourable safety profile of desmoteplase by providing excellent safety and tolerability data. Desmoteplase was well tolerated with adverse events at placebo level. In particular, the mortality was equal between treatment groups and the rate of symptomatic intracranial haemorrhage (the most serious adverse event associated with the current available thrombolytic treatment) after desmoteplase treatment was also comparable to placebo.

"It is obviously disappointing for us, treating physicians and patients that desmoteplase did s not met the primary endpoint in the study, also considering that desmoteplase seems safe and showed an effect in the predefined per protocol population”, said Anders Gersel Pedersen, EVP and head of R&D in Lundbeck and continues “We will now consult with clinical and regulatory experts about the future of the desmoteplase project”.

The DIAS-3 study protocol defined the target population as patients with symptoms of stroke and treatable ischaemic stroke pathology (proximal cerebral vessel occlusion/high-grade stenosis without signs of extensive infarction, intracranial haemorrhage or sub-acute infarction). Analysing only the patients fulfilling the protocol requirements (per protocol population) a favourable effect of desmoteplase was observed relative to placebo measured by mRS. This result is in line with the hypothesis based on the earlier post-hoc analysis of DIAS-2 on the target patient population1.

As a consequence of the failure to meet the primary outcome, but considering the efficacy signal in the per protocol population and the excellent safety and tolerability, further development will be evaluated with advice from key clinical and regulatory experts during the next few months in order to evaluate if a path forward is feasible.

DIAS-3 was a multi-centre, randomised, double-blind, placebo-controlled study in 479 patients from 18 countries in Europe and Asia. Patients with symptoms of stroke and a treatable ischaemic stroke pathology (proximal cerebral vessel occlusion/high-grade stenosis without signs of extensive infarction, intracranial haemorrhage or sub-acute infarction), as assessed by magnetic resonance imaging (MRI) or computerised tomography (CT) scanning were randomised to receive either desmoteplase (90 µg/kg) or placebo within three to nine hours of symptom onset.

Further results of the study will be presented at a scientific congress and published in a scientific journal.

Financial guidance

The content of this release will have no influence on the Lundbeck Group's financial guidance on revenue or core EBIT for 2014 which were provided on 23 June 2014. The status of the desmoteplase program is depending on the internal and external evaluation during the next few months. If the outcome of this evaluation is negative a write-down of DKK 330 million will be recognised in the R&D cost line as communicated earlier this year.

About desmoteplase

Desmoteplase, a fibrin-dependent plasminogen activator, is a genetically engineered version of a clot-dissolving protein found in the saliva of the vampire bat Desmodus rotundus. It has received fast-track designation from the U.S. Food and Drug Administration (FDA) for the treatment of acute ischaemic stroke.

About acute ischaemic stroke (AIS)

Stroke is a medical emergency bringing an enormous burden. The annual incidence rate of stroke in the US varies between 150-200 cases per 100,000 people, corresponding to 795,000 cases. For major 5 European countries (France, Germany, Italy, Spain, UK) the incidence rate is estimated at 110-220 cases per 100,000 people a year, resulting in approximately 700,000 cases annually. In Japan, the reported incidence rate is twice as high as that in Europe and U.S., i.e. 410 cases per 100,000 people a year, leading to approximately 350,000 cases annually. The overall incidence rate in the less developed countries, traditionally lower than that in the developed countries, has surpassed the latter and is still rising.

Stroke is the third biggest cause of disability and the second biggest cause of mortality globally.
