Parkinson’s disease (PD) is a progressive disease characterized by loss of dopaminergic neurons in the substantia nigra, which lead to motor symptoms. Aromatic-L-amino-acid decarboxylase (AADC) converts levodopa into dopamine and glial cell line-derived neurotrophic factor (GDNF) promotes the survival, growth and regeneration of dopaminergic neurons. VGN-R09b is an adeno-associated viral vector (AAV)-based AADC and GDNF combination gene therapy that is delivered to the striatum for the treatment of PD.

The transition from complex and costly ex vivo strategies to platforms that enable direct cellular intervention within the body, known as in vivo therapies, is marking a paradigm change in the field of gene and cell therapies by simplifying manufacturing, improving tissue targeting and expanding clinical access to treatments.

Cala Health Inc.’s KIQ wearable device delivers transcutaneous afferent patterned stimulation through nerves at the wrist that modulate neural activity in the brain and reduces hand tremors in individuals with essential tremor, two recent studies show.
