LONDON, March 16, 2022 /PRNewswire/ -- Leucid Bio ("Leucid" or the "Company"), a biotech company pioneering next-generation cell therapies for hard-to-treat cancers, today notes the publication of two studies in Cell Reports Medicine and Frontiers in Immunology co-authored by its Chief Scientific Officer John Maher.

The research reinforces the conclusion that Leucid's leading technology, parallel CAR (pCAR), has now achieved proof-of-concept across a range of co-stimulatory domains, binders, targets and target combinations in pre-clinical liquid and solid tumour cell lines/models. Professor Maher's technical and scientific expertise in advancing CARs that harness lessons of nature to deliver greater functional persistence is a key driver behind Leucid's technology platform. Leucid's LEU-011 programme is a NKG2D-targeted pCAR T-cell therapy in pre-clinical development for the treatment of solid tumours and haematological malignancies. LEU-011 has potential for the treatment of multiple cancer types as NKG2D ligands are expressed on more than 80% of human tumour cells.

John Maher, Chief Scientific Officer of Leucid Bio, noted: "Our findings confirm that Juxta-membrane localisation is required for effective CAR-mediated co-stimulation and that our proprietary resulting pCAR configurations promote functional persistence of T-cells. As a result, pCAR T-cells have a role in mediating enhanced anti-tumour activity. The data also reinforces the evidence that our pCAR platform delivers enhanced anti-tumour activity through effective provision of dual co-stimulation. pCAR has now been proven across a range of constructs and targets and Leucid is in a leading position to leverage these findings."

Artin Moussavi, Chief Executive Officer of Leucid Bio, added: "John's latest research provides further evidence of the great potential of pCAR and these papers and the accompanying work underpin the activities of the Company and especially the imminent clinical trial. John has been a pioneer in the CAR-T space for decades, and his prolific publication record speaks volumes to his prominence in the field. These recently published studies highlight the strength of the translational research done at John's CAR Mechanics research group and Leucid Bio. I am honored to work with John in translating his findings into patient-driven outcomes."

John Maher has been an early pioneer of CAR T-cell immunotherapy with 100 research papers published over the last three decades. He developed a novel CAR structure, pCAR, in which two co-stimulatory domains are integrated in parallel across the cell membrane. This formation replicates the natural side-by-side position of these molecules across the cell membrane that is seen in endogenous immune receptors. The resulting pCAR T-cells consistently outperform previous generations of CAR T-cells. Professor Maher also worked on the adapter CAR which simulates the configuration adopted by many naturally occurring immune receptors in which the binding and signalling domains are physically separated onto two or more proteins. Leucid's experience has been that this architecture is also compatible with the engineering of CARs with substantial anti-tumour activity.

The recently published papers are as follows:

About Leucid Bio

Leucid Bio is a pioneering biotech company developing cell therapies for refractory cancers, especially solid tumours. Leucid was founded to translate 20 years of King's College London (King's) research in the CAR-T field and is led by a highly experienced management team with both scientific and commercial expertise. As part of Leucid's ongoing relationship with King's, it benefits from exclusive access to and resources from the deep scientific, clinical and manufacturing expertise of John Maher and his academic team of immuno-oncology experts. Leucid is headquartered in London, UK, with operations based at Guy's Hospital with its own 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. 

About John Maher

John Maher is the Scientific Founder and Chief Scientific Officer of Leucid Bio and has worked on CAR T-cell immunotherapy, with a primary focus on solid tumors, for over 20 years.  The first to engineer and develop CD28-based second generation CAR technology in human T-cells, John also leads the "CAR Mechanics" research group at King's College London. He played a key role in the early development of second generation (CD28) CAR technology while a visiting fellow in the lab of Michel Sadelain at Memorial Sloan Kettering Cancer Center, an approach that has achieved significant clinical impact in hematological malignancies. His research group is focused on the development of adoptive immunotherapy using CAR engineered and gamma delta T-cells, with a primary emphasis on solid tumor types. He is Chief Investigator of a Phase 1 clinical trial in which panErbB-specific CAR T-cells are administered to patients with relapsed/ refractory head and neck cancer. John holds an FRCPath in Immunology (by examination) from Royal College of Pathologists and is registered on the General Medical Council specialist register of Clinical Immunologists. He is also a Consultant Immunologist at Eastbourne Hospital.
