A Reliable Option for Reversing Morning Akinesia for Patients With Parkinson Disease

FDA approves once-daily oral tavapadon for Parkinson disease, a first-in-class D1/D5 partial agonist that improves motor function and ON time, with key safety warnings.

Benjamin Walter, MD, MBA, discusses how advances in biomarker testing and genetic characterization are informing Parkinson disease care, alongside developments in adaptive deep brain stimulation and efforts to identify disease earlier.

Seven investigational cerebral palsy therapies—from baby-tooth stem cells to cannabinoids and botulinum toxin—show mixed early results, highlighting key clinical trial milestones ahead.

Late-breaking findings from MDS 2026 suggest a gluten-free diet may affect cognitive and quality-of-life measures in Parkinson disease, although no significant changes in motor function were observed.

Exploratory extracellular vesicle biomarkers suggested KP405, a brain-penetrant GLP-1/GIP agonist, engaged insulin signaling and neuroinflammation pathways in a small phase 1 study.

Early phase 1 findings showed that the PROTAC LRRK2 degrader ARV-102 was associated with improvements in saccadic hypometria and changes in CSF markers of endolysosomal function, neuroinflammation, synaptic integrity, and axonal guidance in participants with Parkinson disease.

Full results from the phase 2b LUMA showed that investigational BIIB122/DNL151 did not slow confirmed clinical worsening in early-stage Parkinson's disease compared with placebo.

New analyses from the D1AMOND clinical program found that 69.8% of participants achieved a clinically meaningful reduction in tic severity within 8 weeks of ecopipam treatment, while an interim 18-month analysis showed sustained improvement without new safety signals.
