About us

Leucid Bio is a clinical stage biotech company pursuing a differentiated approach to develop next generation Chimeric Antigen Receptor T-cell (CAR-T) therapies using the Company’s proprietary Lateral CAR Platform to improve treatment outcomes and save the lives of patients with refractory cancers. Founded, in 2014, to translate 20 years of pioneering CAR-T research led by Dr John Maher at King's College London (KCL),  Leucid has developed a unique Lateral CAR platform that builds upon John’s novel CAR-T model which develops CAR molecules designed to adopt a more natural biological configuration by moving the key functional components into their natural position next to the plasma membrane in a lateral as opposed to a linear configuration – ‘build out, not down’.


Our Company

Leucid Bio is a biotech company pioneering next-generation cell therapies for hard-to-treat cancers. Founded to translate 20 years of pioneering CAR-T research led by Dr John Maher at King's College London (KCL), Leucid Bio has Leucid Bio has developed a proprietary portfolio based upon Dr Maher’s novel approach, in which the CAR structure has been redesigned to recapitulate the lateral distribution of signalling domains as observed in natural immune receptors. The technology gives properties to the CAR-Ts that enable them to consistently outperform previous generations of CAR-T therapies in pre-clinical studies; enhancing T-cell potency and generating a persistent long-term response with reduced toxicity.

Leucid Bio is headquartered in London, UK, with operations based at Guy’s Hospital with its GMP manufacturing and clinical lab facilities, enabling it to maintain its patient-centric focus on developing better cell therapies for the benefit of individuals with hard-to-treat solid tumours.

John Maher



Dr John Maher is a clinically active consultant immunologist at Eastbourne Hospital and King’s Health Partners. While a visiting fellow in the laboratory of Michel Sadelain, he was the first to engineer and test second generation CAR-T technology in human T cells, building on the pioneering work of Helene Finney in the Jurkat model system. He established CAR T-cell research at King’s College London in 2004 where he leads the "CAR Mechanics" group, which is focused on the development of adoptive immunotherapy using CAR engineered and gamma delta T cells. He is chief investigator of a Phase I clinical trial in which a pan-ErbB targeted CAR-T that he developed is being evaluated in patients with refractory locally advanced/ recurrent head and neck cancer.
