Our vision: Transformational outcomes. Uncompromising safety.
Our vision: Transformational outcomes. Uncompromising safety.
At Quell, we see a future where people living with refractory autoimmune disease can achieve safe, transformational and durable resolution of their disease from a single, outpatient dose of engineered nTregs.

Our Ambition
A different kind of cell therapy company



Simple. Scalable. Designed to serve many patients.
Cell therapy can deliver transformational outcomes, but first-generation therapies were built for life-threatening cancers treated in hospital and on platforms that are hard to scale. Autoimmune disease affects millions of people who need therapies that are effective, well tolerated and accessible outside hospital.
Quell is designing engineered nTreg therapies specifically for complex autoimmunity.
One product, many diseases
Developing pipeline-in-a-product candidates, designed to treat multiple complex autoimmune diseases.
Outpatient treatment model
Designing therapies to avoid lymphodepletion chemotherapy and toxicities such as cytokine release syndrome (CRS), local immune effector cell-associated toxicity syndrome (LICATS) so they could be given in the outpatient setting.
Built to scale
Manufacturing built to scale from the outset, with a clear roadmap to automation and lower costs.
People

We also partner with scientific and clinical collaborators at King’s College London, UCL, UHN and Hannover Medical School.
Manufacturing & automation
Every patient with a refractory autoimmune condition should have the option of durable disease control. So, while we develop engineered nTreg therapies, we are also solving cell therapy’s scalability, cost and access challenges. We partner with the best manufacturing and automation partners in the field, who share our goals and values.
