Solengepras

(CVN424)

PARKINSON’S DISEASE

First in class, potent, brain penetrant, non-dopaminergic, GPR6 inverse agonist

Restore balance by regulating just one side of brain circuitry – the indirect pathway

Solengepras (CVN424) targets GPR6 to release the "brake" on movement and restore balance so patients with Parkinson's disease can live with less OFF time.

GPR6 target findings

GPR6, a novel gene, was highly selectively expressed in striatal medium spiny neurons only on the indirect pathway of the basal ganglia circuit as demonstrated by the NETSseq platform below.

signaling pathways in Healthy brain versus brain with parkinson's

Flooding the brain with dopamine replacement (L-DOPA) (or treating patients with drugs that act on dopamine receptors) is NOT precise enough and can cause side effects.

Solengepras (CVN424) offers a novel way of treating Parkinson's disease without the side effects seen with current therapies.

Adjunctive &
Monotherapy

Solengepras (CVN424) is being developed for use across the spectrum of Parkinson's disease, both as an adjunctive treatment as well as for monotherapy use. Cerevance is currently conducting a Phase 2 study as a monotherapy treatment in early, untreated patients with Parkinson's disease with topline data expected in Q1 2025. This study will also demonstrate the potential benefit of solengepras (CVN424) in benefiting quality of life/non-motor symptoms. Cerevance will also initiate a Phase 3 study of solengepras (CVN424) as an adjunctive treatment in the second half of 2024.
