"All six of the approved CAR-T therapies on the market use one of two signaling domains, which were identified 20 years ago. Since then, the ability to read and write DNA has improved dramatically. Ginkgo is harnessing its ability to generate massive libraries of unique CAR designs with different signaling domains, which can then be screened in an assay that mimics a solid tumor environment," said Shawdee Eshghi, Senior Director, Mammalian Engineering, Ginkgo Bioworks. "In head-to-head tests of these designs, Ginkgo is identifying a number of designs that show improved performance compared to designs with standard signaling domains. We’re excited to present this data to the ASGCT (Free ASGCT Whitepaper) community, especially as this flexible platform is available to partners and can also be used for other applications like natural killer cells."

The preclinical validation study aims to test the cell therapy candidate XNK04 alone and in combination with an antibody checkpoint inhibitor against autologous cancer cells isolated from patients with hepatocellular carcinoma (HCC). The study will provide data to support initiation of a potential future clinical phase I/II trial.

"We will explore synergistic effects of the combination. This is a study where we test an individualized NK cell-based therapy on isolated patient-specific tumor material, and it is our ambition to validate this combination approach in HCC," said Johan Liwing, CEO at XNK.

The study will test the hypothesis that the well documented big pharma PD-L1 antibody, when combined with the expanded and activated NK cells, will facilitate NK cell-mediated cytotoxicity against HCC tumor cells.

"We are excited about entering into this collaborative study. This preclinical research agreement with a renowned big pharma company lends valuable support to our clinical strategy and shows that there is strong interest in the industry for our technology," said Markus Thor, Chief Business Officer at XNK.

The HCC study adds to XNK’s clinical phase II program in multiple myeloma and preclinical programs in urothelial cancer and acute myeloid leukemia (AML). XNK retains all commercial rights to XNK04.

About Hepatocellular Cancer

Cancer in the liver is a major health problem and is the fourth leading cause of cancer-related death worldwide. Each year more than 800,000 people are diagnosed with liver cancer worldwide. HCC constitutes around 80% of all primary liver cancers. Risk factors for developing HCC include e.g. fatty liver disease, alcohol consumption and hepatitis B and C. Treatments include surgery, trans-arterial chemoembolization (TACE), chemotherapy, targeted drug therapy and checkpoint inhibitors. The medical need remains significant with high recurrence rates and with 5-year survival rates around 20%.

On May 4, 2023 Sapience Therapeutics, Inc., a clinical-stage biotechnology company focused on the discovery and development of peptide therapeutics to address oncogenic and immune dysregulation that drive cancer, reported that it was awarded a $2 million, two-year Small Business Innovation Research (SBIR) grant from the National Cancer Institute (NCI) of the National Institutes of Health (NIH) (Press release, Sapience Therapeutics, MAY 4, 2023, View Source;catenin-antagonist-301816245.html [SID1234631069]). The proposed non-clinical studies will investigate pharmacodynamic biomarkers for ST316, a first-in-class β-catenin antagonist, and evaluate the impact of ST316 on the tumor microenvironment (TME) in patient-derived cancer models.

"This award provides further validation of our novel approach with ST316 to impact the Wnt/β-catenin signaling pathway, a known oncogenic driver of many cancers and a key regulator of the tumor microenvironment," said Jim Rotolo, Ph.D., SVP, Translational Pharmacology and Head of Research of Sapience Therapeutics. "ST316 has tremendous therapeutic promise, with a robust preclinical data package that includes a favorable safety profile and significant anti-tumor activity. We look forward to building upon these data with this grant award and evaluating ST316 in patients in our upcoming Phase 1-2 clinical study."

ST316 is a first-in-class peptide antagonist of the interaction between β-catenin and its co-activator BCL9, a complex that drives oncogenesis in multiple cancers where aberrant Wnt/β-catenin pathway signaling is observed. In March 2023, Sapience announced that it received clearance from the U.S. Food and Drug Administration (FDA) to proceed with a Phase 1-2 clinical trial of ST316 for the treatment of solid tumors. In addition, at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2023, Sapience presented late-breaking data on ST316 highlighting its immunotherapeutic potential.

The award will utilize patient-derived xenograft (PDX) models to investigate pharmacodynamic (PD) biomarkers and evaluate the impact of ST316 on the TME, namely macrophage polarization, tumor infiltrating lymphocyte (TIL) expression in tumors and the impact in combination with a PD-1 inhibitor.

About ST316

ST316, a first-in-class β-catenin antagonist, is in Phase 1 clinical development following the clearance of its Investigational New Drug (IND) application by the U.S. Food and Drug Administration in March 2023. β-catenin is a critical member of the canonical Wnt signaling pathway, a well-known development stage pathway that has been considered an "undruggable" cancer target, as small molecules have proven ineffective or toxic. Disruption of the interaction between BCL9 and β-catenin with ST316 reduces oncogenic Wnt-signaling, suppressing transcription of Wnt target genes resulting in tumor cell death and a pro-inflammatory tumor microenvironment, without disruption of homeostatic Wnt function.

In the second quarter of 2023, the Phase 1 dose-escalation portion of the Phase 1-2 study will begin enrolling patients with selected advanced solid tumors likely to harbor abnormalities of the Wnt/β-catenin signaling pathway. The Phase 2 dose-expansion portion aims to continue to assess the safety of ST316 as well as proof of concept in four specific tumor types known to harbor abnormalities of the Wnt/β-catenin signaling pathway.

TNBC is the most aggressive type of breast cancer in women with a 5-years survival rate of 66% and a very low survival rate of 12% after metastasis. Conventional cancer treatments often come with severe side effects, limiting their use and efficacy. Furthermore, targeted therapies and new immunological treatments suit only a limited patient population, while drug resistance can develop rapidly. CRB091 offers a well-tolerable and effective therapy that could address the shortfalls of existing treatments.

CRB091’s active molecules have been proven safe for human use, and CRB anticipates initiating the first-in-human clinical trials in the US in 12 months. The FDA’s Pre-Investigational New Drug (Pre-IND) application advice is scheduled in Q3 2023, with the IND filing in Q3 2024.

As a preclinical oncology company, CRB is focused on developing drugs that address the metabolic disease that induces carcinogenesis. By providing a particularly effective and well-tolerated therapy, CRB091 has the potential to significantly improve the treatment of triple-negative breast cancer and other difficult-to-treat cancers.

With the meaningful efficacy demonstrated on human cancer cell lines, the Switzerland-based startup is poised to take a significant step towards human use of the novel treatment.
