Parkinson's Disease Drug Repurposing Consortia
Introduction
Drug repurposing for Parkinson's disease has emerged as a critical strategy to accelerate the development of disease-modifying therapies. Multiple international consortia, patient organizations, and research networks have been established to identify, evaluate, and advance existing drugs for Parkinson's treatment. This page provides an overview of the major consortia and their collaborative efforts.
Major Consortia
1. Linked Clinical Trials (LCT) Program
Lead: [Cure Parkinson's](/institutions/cure-parkinsons) (UK)
An international clinical trials program that has reviewed over 200 compounds and advanced 30+ repurposed drugs into clinical trials. The program brings together leading researchers, pharmaceutical companies, and people with Parkinson's to accelerate disease-modifying therapies.
- Established: 2009
- Compounds reviewed: 200+
- Trials initiated: 30+
2. Parkinson's UK Drug Club
Lead: [Parkinson's UK](/institutions/parkinsons-uk) (UK)
A systematic drug screening initiative focusing on approved drugs with potential neuroprotective effects in Parkinson's. The program leverages a network of UK research centers and patient cohorts.
- Established: 2017
- Annual investment: £2-3M
- Active trials: 10+
3. NIH Parkinson's Disease Repurposing Program
Lead: [NINDS](/institutions/nih-ninds) and [NIA](/institutions/nih-nia) (USA)
