Motor fluctuations in Parkinson disease - a mini-review of emerging drugs.
(PubMed, Expert Opin Emerg Drugs)
- "Preliminary results of a phase III study of dopamine D1/D5 agonist tavapadon and phase II of CVN424, a GRP6 inverse agonist suggest improved ON time. Negative studies were reported with foliglurax (MGluR4 inverse agonist) and the repurposed drugs naftazone and bumetanide. Several novel targets are in early-stage development with results awaited. Overall, it is unclear whether the field is significantly further ahead, as the benefit of these emerging drugs in comparison with currently available agents for motor fluctuations needs to be clarified."

HOW THE THERAPEUTIC APPROACH TO EARLY PARKINSON'S DISEASE WILL CHANGE IN THE NEXT FUTURE
(ADPD 2025)
- "Levodopa remains the most efficacious drug, a better preparation of levodopa like IPX 203 can ensure more stable plasma levels of Levodopa...Tavapadon is a new dopamine agonist stimulating D1-D5 receptors which concluded the phase III. Other compounds such as CVN424 (Cerevance) orally active and selective GPR6 inverse agonist, piperamat (IRLAB 752) a cortical enhancer to improve balance, Clenbuterol/Nadolol for cognition, mesdopetam a D3 antagonist are under investigation...These include the monoclonal antibody prasinezumab, UCB0599 and buntanetap small-molecules α-synuclein aggregation inhibitor, the vaccine ACI-7104.056 by AC immune...The LRKK2 kinase inhibitor BIIB122/DNL151 is in phase IIb in PD. BIAL BIA 28-6156 activator of the GCase enzyme is under investigation in patients with GBA mutation. The combination of symptomatic and disease modifying therapy, the use of accurate biomarkers and more precise treatment will be the future in the treatment of PD."

NETSseq Identifies Novel Therapeutic Targets for Neurodegenerative Diseases
(AAN 2025)
- "Based on the highly specific localisation and the biological function of GPR6 in models of PD, we developed solengepras (CVN424), which in a Phase 2 study was demonstrated to be generally well-tolerated and provided clinically meaningful activity in PD (Brice et al 2022/2024)...In conclusion, NETSseq has the potential to identify cell specific gene targets and biological insight into human brain disorders, which can be developed into novel therapies for neurodegenerative diseases."

Structural insights into the high basal activity and inverse agonism of the orphan receptor GPR6 implicated in Parkinson's disease.
(PubMed, Sci Signal)
- "Here, we solved crystal structures of GPR6 without the addition of a ligand (a pseudo-apo state) and in complex with two inverse agonists, including CVN424, which improved motor symptoms in patients with Parkinson's disease in clinical trials...A combination of site-directed mutagenesis, native mass spectrometry, and computer modeling suggested potential mechanisms for high constitutive activity and inverse agonism in GPR6 and identified a series of lipids and ions bound to the receptor. The structures and results obtained in this study could guide the rational design of drugs that modulate GPR6 signaling."

Cerevance Announces Publication of Positive Phase 2 Results of Solengepras for the Treatment of Parkinson’s Disease in eClinicalMedicine
(GlobeNewswire)
- P2 | N=136 | NCT04191577 | Sponsor: Cerevance Beta, Inc. | "On Day 27, the change from baseline in daily OFF time was -1.6 hours (p <0.0001) in the solengepras 150 mg group, -1.3 hours (p <0.01) in the solengepras 50 mg group, and -0.5 hours in the placebo group. The placebo-adjusted least squares mean treatment difference was statistically significant for the solengepras 150 mg dose at -1.3 hours (p=0.0225). Decreases in OFF time were accompanied by trends towards increased total daily ON time without troublesome dyskinesia (Good ON time). The placebo-adjusted least squares mean treatment difference for good ON time was +0.67 (p=0.27) with the solengepras 150 mg dose...In the supplementary post-hoc analysis, treatment with solengepras 150 mg group reduced OFF time by -1.78 hours (p= 0.0045) compared to placebo and increased good ON time by +1.3 hours (p=0.04)...Solengepras was generally well tolerated, and no serious treatment-related adverse events were reported."
