Positive Phase 3 Results for Tavapadon in Parkinson's Disease Trial

Cerevel Therapeutics has reported positive results from the TEMPO-3 trial, a Phase 3 study of tavapadon as an adjunctive treatment for Parkinson's disease. The trial showed that patients who received tavapadon along with levodopa (LD) had a significant increase in total "on" time without troublesome dyskinesia compared to those on LD and placebo. The drug was well-tolerated, with a safety profile in line with previous trials.

Tavapadon, a D1/D5 receptor partial agonist, is being studied for its potential to provide a balance of motor control, safety, and tolerability for individuals with Parkinson's. The TEMPO-3 trial's positive outcome is particularly encouraging as it suggests that tavapadon could offer a new treatment option for those living with this debilitating disease.

Parkinson's disease is a progressive neurodegenerative disorder affecting movement and currently has a growing patient population. The need for innovative treatment options that can provide sustained motor control without severe side effects is significant. Tavapadon's mechanism of action, selectively activating D1/D5 dopamine receptors, may help achieve this balance.

Cerevel Therapeutics, based in Cambridge, Massachusetts, is focused on developing treatments for neuroscience diseases. The company's pipeline includes several clinical-stage investigational therapies targeting a range of conditions, including Parkinson's disease.

The TEMPO-3 trial was a 27-week, double-blind, randomized, placebo-controlled study involving 507 adults with Parkinson's disease. Participants received either tavapadon adjunctive to LD or placebo and LD once daily. The trial's primary endpoint was the change from baseline in total "on" time without troublesome dyskinesia, with key secondary endpoints including changes in total daily "off" time and scores on the Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS).

Full results from the TEMPO-3 study are expected to be presented at future medical meetings and will be used to support regulatory submissions for tavapadon as a Parkinson's disease treatment. Results from the Phase 3 monotherapy trials TEMPO-1 and TEMPO-2 are anticipated in the latter half of 2024.

Cerevel Therapeutics is committed to advancing the understanding and treatment of brain disorders, with an aim to develop new therapies that can improve the lives of those affected by neurological conditions. The positive findings from the TEMPO-3 trial represent a step forward in the search for effective treatments for Parkinson's disease.
