The US Food and Drug Administration (FDA) has approved Capsida Biotherapeutics’ investigational new drug (IND) application for CAP-003 to treat Parkinson’s disease (PD).
The clearance allows CAP-003, an intravenously administered gene therapy, to proceed to clinical trials for treating PD associated with glucocerebrosidase (GBA) mutations (PD-GBA).
This is Capsida’s second completely owned clinical programme that has successfully navigated through IND clearance.
CAP-003 leverages an engineered capsid capable of crossing the blood-brain barrier and delivering targeted genetic material while minimising off-target tissue effects.
The company plans to commence the Phase I/II study for CAP-003, with the first subject anticipated to receive the dose in the third quarter of 2025.
Capsida Biotherapeutics chief medical officer Swati Tole stated: “PD-GBA is an area of substantial unmet need given the lack of approved treatments that target GCase [glucocerebrosidase], which is the protein encoded by the GBA gene, and provide meaningful slowing or halting of disease progression.

By GlobalData“We recognise the urgency for new treatment approaches, so we are working diligently to initiate the Phase 1/2 clinical trial for CAP-003 with the aim of dosing the first patient in the third quarter of this year.”
Mutations in GBA are prevalent in up to 15% of individuals with PD and pose the most significant genetic risk factor for developing the disease.
Studies have shown that patients exhibit around a 30% deficit in GCase enzyme activity compared to healthy subjects, yet no approved treatments address this issue or modify disease progression. Capsida has a central nervous system pipeline comprising disease-modifying and potentially curative treatments intended for rare as well as more common diseases across all ages.
