H. Lundbeck A/S today announced that Lu AE58054 has met its primary endpoint in a fixed dose, randomized, placebo-controlled clinical study in 278 patients suffering from Alzheimer’s disease.
The investigational compound, Lu AE58054 is a novel, selective 5HT6 receptor antagonist with a different mechanism of action than currently available Alzheimer’s medications.
Augmentation therapy with Lu AE58054 (plus10mg/day donepezil) at the selected dose resulted in statistically significant improvement in cognition, as measured by the ADAS-cog (Alzheimer’s Disease Assessment Scale-cognitive sub-scale) over a 24 week treatment period versus placebo (plus10mg/day donepezil). Secondary endpoints, including measures of global status and activities of daily living also showed positive trends with the addition of Lu AE58054, compared with patients who only received donepezil.
Treatment with Lu AE58054 in this study was well tolerated.
“These results are very encouraging, and we are now evaluating how to best proceed with the development of Lu AE58054,” says Executive Vice President Anders Gersel Pedersen, Head of Research & Development at Lundbeck, and continues: “We believe that there is a strong need for better treatments for patients with Alzheimer’s disease, and Lundbeck sees Lu AE58054 as a potential new treatment option for this devastating disease.”
The study was conducted in 278 patients suffering from moderate Alzheimer’s disease, and Lu AE58054 was administered as add-on to donepezil, a commonly used acetylcholinesterase inhibitor for a period of 24 weeks. In the study, Lu AE58054 as adjunctive treatment to donepezil was compared with placebo plus donepezil. Lu AE58054 (plus donepezil) demonstrated significant improvements in cognitive function in Alzheimer’s disease compared to placebo (plus donepezil), as assessed by ADAS-cog. Lu AE58054 was considered overall to be well tolerated at the selected dose.
The study was conducted in selected European countries as well as Canada and Australia.
Lundbeck is now evaluating the future development strategy of Lu AE58054 with the intention to initiate a major pivotal clinical programme potentially including development and commercial partnerships.
Full data from this study will be made available through scientific disclosure at upcoming medical congresses and in scientific publications.
About Lu AE58054
Lu AE58054 is a potent and selective 5-HT6-receptor antagonist. The 5-HT6-receptor is primarily found in areas of the brain involved in cognition. A number of early trials have demonstrated that a 5-HT6-receptor antagonist could offer potential benefits in the treatment of disorders such as Alzheimer’s disease and in December 2009 Lundbeck initiated the above described 24 week clinical phase II trial with Lu AE58054 as augmentation therapy in Alzheimer’s disease.
About Alzheimer’s disease
Alzheimer’s disease is a progressive brain disorder, in which the brain gradually degenerates. It most frequently occurs in people aged above 65-70 years. People with Alzheimer’s disease develop distressing changes in memory, thought, function and behaviour, which worsen over time. These changes increasingly impact upon the person’s daily life, reducing their independence, until ultimately they are entirely dependent on others.
Alzheimer’s disease also has an enormous impact on the patient’s caregiver. Most caregivers are close relatives who provide care in the home – a demanding and exhausting role that represents an emotional and physical burden.
Alzheimer’s disease damages and kills brain cells, leading to significant brain shrinkage and neurotransmitter imbalances. As the brain cells degenerate, characteristic waste accumulates in the brain, known as ‘plaques’ and ‘tangles’.
Worldwide, 36 million people have dementia. Perhaps as many as 28 million of the world’s 36 million people with dementia have yet to receive a diagnosis and, therefore, do not have access to treatment, information and care. Every year, an estimated 4.6 million new cases are identified[2]. With the shift towards an increasingly elderly population, it is predicted that the number of people affected by dementia will almost double every 20 years, and by the year 2050, 115 million people will have the condition.
Alzheimer’s disease is the most common cause of dementia, accounting for 50-70% of cases.
The worldwide costs of dementia (USD 604 billion in 2010) amount to more than 1% of gross domestic product (GDP).
