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. 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’.

Who We Are
Leucid Bio is led by industry veterans with deep scientific, clinical and commercial expertise in the CAR-T field, supported by a diverse group of passionate and dedicated team members. Together, the Leucid Bio team has a proven track-record in the engineering of new chimeric immune receptor systems and their translation to the clinic. The Company is headquartered in London, UK, with operations based at Guy’s Hospital.

CEO
John Maher
CSO

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.
