Coya Therapeutics is pursuing a novel therapeutic goal for ALS: making the condition "livable" by stopping its progression. Instead of aiming for a cure or reversing existing damage, their strategy focuses on preserving a patient's current motor function, which would represent a significant breakthrough in managing the neurodegenerative disease.
Coya's therapeutic approach is not limited to ALS. The company views the underlying mechanism—dysfunctional regulatory T-cells driving neuroinflammation—as a common pathway in other conditions like frontotemporal dementia, Alzheimer's, and Parkinson's. This positions their drug as a platform technology, creating a broader pipeline and de-risking the company from reliance on a single indication.
Coya's treatment is a combination therapy that addresses two problems simultaneously. One component increases the number of functional regulatory T-cells (Tregs) to control the immune system. The second component suppresses the underlying inflammation that would otherwise cause these newly boosted cells to become dysfunctional again, ensuring a more durable effect.
For its Phase 2 ALS trial, Coya implemented a patient-centric design to encourage participation. It uses a 2:1 randomization, giving participants a higher chance of receiving the drug. Crucially, it also includes a crossover component where placebo patients are guaranteed to receive the active treatment after six months, addressing ethical concerns and improving enrollment appeal for a fatal disease.
