Lundbeck acquires Prexton Therapeutics and foliglurax ,a promising treatment for Parkinson's disease.

H. Lundbeck A/S and Prexton Therapeutics BV announced signing of a definitive agreement in which Lundbeck will acquire Prexton. Under terms of the agreement, Lundbeck will pay EUR 100 million (approximately DKK 750 million) upfront and is furthermore required to later pay up to EUR 805 million (approximately DKK 6 billion) in development and sales milestones to the group of current owners.

By acquiring Prexton, Lundbeck will obtain global rights of an attractive compound foliglurax, which currently is in clinical phase II testing for symptomatic treatment of OFF-time reduction in Parkinson's disease and dyskinesia including Levodopa Induced Dyskinesia (LID). First data from the ongoing clinical phase II programme is expected to be available during the first half of 2019.

Foliglurax works by stimulating a specific glutamatergic target (mGluR4) which activates a compensatory neuronal system in the brain which is largely unaffected in Parkinson's disease. Animal models have convincingly demonstrated positive effects in models of Parkinson's disease. The aim is to treat the motor symptoms of Parkinson's disease, such as resting tremor, muscle rigidity and uncontrolled movements (dyskinesia).Lundbeck will pay EUR 100 million upfront to the current investors of Prexton Therapeutics BV. Furthermore, Lundbeck is required to pay up to EUR 805 million in development, regulatory and sales milestones depending on successful outcome of certain undisclosed milestones. More than half of the EUR 805 million is connected to sales milestones.
