The Big Give Christmas Challenge 2025

Double your impact for people living with Parkinson’s
We’re delighted to be taking part once again in the Big Give Christmas Challenge, the UK’s biggest match-funding campaign.
For one week only, every donation you make through the Big Give website will be doubled, meaning your support can go twice as far in the search for a cure.
What is the Big Give?
The Big Give Christmas Challenge brings together charities, match funders and the public to make an incredible difference each year. For seven days, every pound donated via the Big Give platform is matched, turning £20 into £40, £50 into £100, and so on, until the match pot runs out.
It’s a powerful way to make your generosity go further and help accelerate breakthroughs in Parkinson’s research.
This year’s campaign will run from midday Tuesday 2 December to midday Tuesday 9 December.
During that week, all donations made through the Big Give to Cure Parkinson’s will be matched, doubling the difference you make.
EJS ACT-PD: The world’s largest clinical trial for Parkinson’s
This year’s Big Give will support EJS ACT-PD, a pioneering new platform trial testing multiple potential Parkinson’s treatments at once.
Traditionally, every time a new drug can be tested, a clinical trial must be developed from scratch (protocol, infrastructure, recruitment, and funding). It is comparable to building a football stadium, playing a single game, and then dismantling the stadium, only to restart the process for each trial.
What’s needed is a smarter approach: EJS ACT-PD is the first multi-arm multi-stage (MAMS) clinical trial platform for Parkinson’s in the UK – and the world’s largest clinical trial for Parkinson’s.
Multi-arm multi-stage platform trials allow for the assessment of several potential therapies simultaneously against a single placebo, reusing the same infrastructure to increase the pace of scientific progress.
It’s faster, more efficient, and could transform the future of Parkinson’s research.
Ultimately, the launch of the platform represents a leap forward in our goal of finding a therapy able to slow, stop, or reverse Parkinson’s progression.
The first phase of the trial will involve 1,600 people living with Parkinson’s, with over 40 sites opening across England, Wales, Scotland, and Northern Ireland. This means there’s more opportunity than ever before for people with Parkinson’s to participate in clinical research.
This year, thanks to our incredibly generous match funders, Cure Parkinson’s supporter Andrew Moncreiff and Michael Strong, we aim to hit an ambitious £120,000 target.
Your support will help us reach our £120,000 target, and every pound you give between Tuesday 2 and Tuesday 9 December will be doubled.
