Genomic biomarkers are only relevant for approximately 15% of tumors, thus limited in use. Protein-level biomarkers can predict patient populations not seen by genomic means, by directly measuring proteins, their interactions, and their functions. To tap into the potential of protein-level data, Protai has built a proteomics AI-based platform that comprehensively maps the course of a disease on the protein level. Its technology allows it to better predict which patients will respond to a given drug, as well as discover novel drug targets that were missed by genomic approaches. These discoveries may be the key to significantly accelerating drug discovery and clinical development, lowering the time and costs of R&D.

Since its initial funding last year, Protai has opened laboratories at its Israel R&D center for data acquisition, biological validation and drug discovery activities and recruited an experienced drug discovery team with significant experience in successfully bringing drugs to the clinic. Additionally, Protai established collaborations with several leading hospitals, and now has access to over 100k well-defined banked samples for its comprehensive tumor mapping process, focused on gyno-oncology and lung cancer indications.

With the additional funding, Protai will expand its activities to include an oncology drug discovery pipeline, initially focusing on targets with a clearly-defined novel patient population biomarker, derived from its AI proteomics platform. To help navigate these efforts, the company has added Dr. Sharon Shacham, a serial biotech entrepreneur and Founder of Karyopharm Therapeutics, to Protai’s Board of Directors. In addition, Protai is supported by leading oncology experts, including Prof. Giulio Draetta, Chief Scientific Officer at MD Anderson and former Pharma executive; Prof. Bradley J. Monk, Director of Gynecologic Oncology at the University of Arizona College of Medicine; Prof. Funda Meric-Bernstam, Chair of the Department of Investigational Cancer Therapeutics at MD Anderson Cancer Center, and Dr. Jurgen Moll, former Head Molecular Oncology, Sanofi Vitry.

This round of financing will accelerate its further expansion of its existing product pipeline and rapid transformation to the clinical stage.

Globally, adoptive cell therapy has demonstrated excellent disease remission rates and survival advantages compared to chemotherapy and traditional immunotherapy, and has become a hot spot for biomedical innovation. In recent years, cell therapy based on TCR (T cell receptor) has gradually begun to show its unique charm after years of technological accumulation, especially in the treatment of advanced malignant solid tumors. TCR recognition signal is the first signal of T cell activation in immune surveillance. TCR can recognize a wider range of intracellular antigens than CAR, and the resulting activation of tumor-specific T cells is targeted at tumors (especially solid tumors). The most critical step in the cellular immune response. Currently, TCR-T therapies targeting tumor-related antigens such as MAGE-A4 and NY-ESO-1 have achieved considerable efficacy in clinical trials. However, the expandable indications of TCR-T drugs targeting these targets are relatively limited. How to target neoantigens (neoantigens) produced by tumor driver gene mutations that cover a wider range of population indications and discover extremely low-frequency natural TCR sequences with high affinity and guaranteed safety is the bottleneck of the current TCR-T cell therapy industry. question.

Because of this, biotechnology companies focusing on "new antigen target discovery" and "natural TCR" in the past two years are setting off an increasing wave in the international capital market. In March 2022, Affini-T completed a US$175 million Series A financing, expanding the potential application areas of cell therapy to lung cancer, colorectal cancer and pancreatic cancer; in January 2023, AstraZeneca announced that it would acquire clinical trials for US$320 million. Neogene, a TCR-T R&D company in the previous stage, uses this to enter the TCR-T cell therapy track.

Xinjing Zhiyuan complies with the general trend of industry development and is at the forefront of the industry in the discovery of neoantigens and natural TCRs. Its powerful discovery platform has accumulated thousands of neoantigen target-natural TCR data, which has not only lifted the last hurdle in the TCR-T field.
