10:25 – 10:30 AM EST (4:25 – 4:30 PM CET)

"PARP1 selective agents offer the promise of delivering effective PARP inhibition while mitigating the hematologic and GI toxicity associated with first generation PARP inhibitors," said Patricia LoRusso, D.O., Ph.D., Associated Center Director for Innovative Medicine at Yale Cancer Center. "By optimizing PARP1 selectivity and potency, SNV1521 has the potential to emerge as a best-in-class agent with a differentiated safety profile compared to standard of care and PARP inhibitors in development."

Synnovation also announced a clinical collaboration with DualityBio to evaluate the combination of SNV1521 with Duality’s HER3-directed antibody-drug conjugate (ADC), DB-1310. DB-1310 is a novel ADC targeting HER3 developed using DualityBio’s proprietary DITAC platform. In June 2025, Dr. Aaron E. Lisberg from the University of California, Los Angeles (UCLA) presented the first-in-human Phase I/IIa clinical trial data (NCT05785741) of DB-1310 in an oral session at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. The results demonstrated encouraging efficacy and a manageable safety profile in patients with advanced solid tumors who had failed standard therapies.

"The combination of cytotoxic agents with PARP inhibitors has shown clear preclinical synergy, however, overlapping hematologic toxicity has so far hindered the successful co-development." said Wenqing Yao, Ph.D., CEO and Co-Founder at Synnovation. "This collaboration provides an exciting opportunity to evaluate the combination of two potentially best-in-class therapies—a heme-sparing, PARP1-selective inhibitor, SNV1521, and the HER3-targeting ADC, DB-1310—with the aim of demonstrating synergistic efficacy and improving patient outcomes".

Abstract: 2242
Title:Preclinical development of GNTbm-TKI, a novel multi-receptor tyrosine kinase inhibitor, while combined with GNTbm-38 showing potent induced tumor microenvironment remodeling activity in cancer immunotherapy
Session Date/Time: 10/19/2025, 12:00-12:45 CEST
Poster Board Number: 1577P

Currently, although there are many options for cancer immunotherapy, they still cannot meet the needs of clinical treatment, especially for advanced solid tumors defined as ‘cold tumors’. Genetic alterations of certain receptor tyrosine kinases (TKs), including TAM (TYRO3, AXL, and c-MER), are critical in creating environment conducive to tumor development in several cancers such as HNSCC, CRC, HCC, and RCC. GNTbm-TKI is a novel multi-targeted TKI, showing induction of immune activation in the tumor microenvironment (TME), that indicates the potential application in cancer immunotherapy for unmet medical needs.

The results of the study show that GNTbm-TKI strongly inhibited the activities of TYRO3, AXL, c-MER, BTK, ROS1, NTRK2, MET, and VEGFR2 at nanomolar level. GNTbm-TKI showed anti-proliferation activity in NCI-60 human cancer cell lines with low GI50 values. GNTbm-TKI showed a superior in vivo efficacy in WT mice compared to immune-deficient mice in CT-26 model, indicating anti-cancer immune activation induced by the treatment. Furthermore, treatment with GNTbm TKI + GNTbm-38 (an immune activator of class ⅠHDACi) combined with ICI significantly improved tumor response rate and boosted survival rate through synergistic effect by normalizing tumor vessels, increasing activated CD8+ T cell infiltration into tumors, inducing memory T cell persistence, and strongly inhibiting mobilization of immunosuppressive cells into tumors. On the other hand, GNTbm-TKI + GNTbm-38 combined with anti-PD-1/VEGF bispecific antibodies in a humanized B-PD-1/PD-L1/VEGFA mouse model also greatly improved anti-cancer with a strong synergistic effect.

GNTbm-TKI is a potent immune-activating multi-tyrosine kinase inhibitor, and it is surprisingly found capable of significantly reshaping the tumor microenvironment when combined with GNTbm-38. When further combined with ICI or anti-PD-1/VEGF bispecific antibodies, it can greatly enhance anti-cancer efficacy, providing a scientific basis for future clinical trials.

About GNTbm-TKI
GNTbm-TKI is a new chemical entity independently developed by GNTbm. It is a drug candidate selected by an immuno-competent tumor-bearing animal testing platform, and has undergone many preclinical research studies to be demonstrated that it has very outstanding anti-cancer activity in tumor microenvironment. GNTbm-TKI is an oral drug with dual effects of strong immune activation and multi-tyrosine kinase, which is unique when compared to the mechanism of other TKI drugs. GNTbm-TKI can remodel the tumor microenvironment (TME) through a unique multiple regulatory mechanism based on its kinase targets which it selectively inhibits. GNTbm-TKI strongly inhibits tumor growth and development, suppresses tumor invasion and metastasis, inhibits tumor angiogenesis, and most importantly, possesses potent tumor immune regulatory activity. When GNTbm-TKI is combined with GNTbm-38, based on their respective unique mechanisms, they have a complementary and powerful tumor microenvironment remodeling function, capable of converting ‘cold tumors’ into ‘hot tumors.’ When further combined with ICI or anti-PD-1/VEGF bispecific antibodies, they exhibit exceptionally superior anti-tumor immuno-oncology activity, which can attract CTL to infiltrate into the TME, and activate CTLs and reduce CTL exhaustion. At the same time, it can also reduce the attraction of immunosuppressive cells (such as: TAM, Treg, and MDSCs) into the TME, so as to achieve the remodeling of the TME, which is more conducive to obtaining the therapeutic benefits of cancer immunotherapy. GNTbm-TKI monotherapy can be used in the treatment of advanced neuroendocrine tumor, and GNTbm-TKI can also be combined with GNTbm-38 or/and ICI/anti-PD-1/VEGF bispecific antibodies for treatment of a variety of solid tumors, mainly through a unique anti-cancer immune-regulating and multiple-tyrosine kinase inhibition mechanism to achieve anti-cancer treatment goals.

7MW4911 is an investigational CDH17-targeting ADC developed using Mabwell’s proprietary IDDC platform. Its highly optimized structure integrates three key elements:

– Mab0727: A highly specific CDH17 monoclonal antibody with rapid internalization properties, cross-species (human/monkey) moderate affinity, and minimal off-target binding.

– Novel cleavable linker: Ensures precise payload release in tumor tissues.

– MF-6 payload: A proprietary DNA topoisomerase I inhibitor designed to overcome multidrug resistance (MDR), exhibiting superior plasma stability, controlled drug release, and potent bystander effects.

In July 2025, Mabwell published preclinical data in Cell Reports Medicine ("Overcoming multidrug resistance in gastrointestinal cancers with a CDH17-targeted ADC conjugated to a DNA topoisomerase inhibitor"), demonstrating 7MW4911’s tumor-selective cytotoxicity via CDH17-mediated internalization. Key advantages include:

– Optimized molecular design: Homogeneous drug-to-antibody ratio (DAR=4, >95%) and stable linker confer exceptional plasma stability, while membrane-permeable MF-6 drives potent bystander killing.

– Broad Antitumor Efficacy: Demonstrates robust tumor regression in colorectal, gastric, and pancreatic cancer PDX/CDX models, including tumors with RAS/BRAF mutations and diverse Consensus Molecular Subtypes (CMS).

– MDR resistance: Outperforms MMAE/DXd-based ADCs in ABC transporter-mediated MDR models and reverses tumor progression post-ADC treatment.

– Target versatility: Active even in tumors with low-to-moderate CDH17 expression, expanding potential patient eligibility.

– Favorable safety profile: Limited tissue distribution in mice, controllable pharmacokinetics (moderate half-life, no accumulation), and a wide therapeutic window in cynomolgus monkeys, with no significant toxicity signals.

With this profile, 7MW4911 emerges as a promising therapeutic candidate for advanced gastrointestinal cancers. 7MW4911 has also received IND clearance from US FDA to initiate clinical study in patients with advanced colorectal cancer and other advanced gastrointestinal tumors.

About CDH17

CDH17 is a pan-cancer validated target with restricted expression in normal intestinal epithelium but marked overexpression in gastrointestinal cancers (e.g., colorectal, gastric, pancreatic). Its aberrant expression correlates with tumor metastasis and poor prognosis, positioning it as an ideal therapeutic target.
