Abstract:

Clinical studies have demonstrated the antitumor efficacy of covalent KRAS G12C inhibitors in treating advanced/metastatic cancers. In the current study, we report the preclinical characteristics of a specific KRAS p.G12C covalent inhibitor, glecirasib. Glecirasib exhibited high potency against KRAS G12C, along with a high level of selectivity over wild-type KRAS, HRAS, and NRAS in biochemical assays. On the cellular level, it substantially reduced downstream ERK and AKT phosphorylation, inhibited the viability of cancer cells harboring the KRAS p.G12C mutation, and demonstrated high selectivity over non-KRAS p.G12C cancer cells. Glecirasib could effectively inhibit HRAS G12C, NRAS G12C, and several G12C-inclusive KRAS double mutants that showed resistance to adagrasib. In vivo research suggested that once-daily dosing of glecirasib can robustly inhibit ERK phosphorylation for at least 24 hours and induced tumor regression in several xenograft models, including the NCI-H1373–luciferase intracranial model. Glecirasib in combination with cetuximab or JAB-3312 (sitneprotafib, a clinical-stage SHP2 inhibitor developed by Jacobio Pharma) significantly enhanced antitumor activity both in vitro and in vivo. Collectively, these results suggest that glecirasib is a potent and selective covalent inhibitor of KRAS G12C, shows potent antitumor activity as monotherapy, and synergizes with either EGFR blockade or SHP2 inhibition. A new drug application for glecirasib has been submitted in China, seeking approval for the treatment of non–small cell lung cancer, supported by a pivotal phase II single-arm study (NCT05009329). Additionally, glecirasib is being explored in clinical trials in combination with cetuximab (phase II, NCT05194995) and JAB-3312 (phase III, NCT06416410).

Significance::

Glecirasib potently and selectively inhibits KRAS G12C and reduces ERK and AKT phosphorylation in KRAS G12C–mutant cancer cells, further inducing cell-cycle arrest and apoptosis. Glecirasib monotherapy leads to tumor regression in KRAS G12C–mutant animal models and shows synergistic effects with cetuximab or JAB-3312 (sitneprotafib).

Discovery of JAB-3312, a Potent SHP2 Allosteric Inhibitor for Cancer Treatment

Article

Author: Xu, Zilong ; Wu, Xinping ; Kang, Di ; Wang, Yanping ; Zhang, Lei ; Wang, Yinxiang ; Gao, Panliang ; Zhang, Wei ; Long, Wei ; Ma, Cunbo ; Cai, Yang ; Han, Huifeng

As an oncogenic phosphatase, SHP2 acts as a converging node in the RTK-RAS-MAPK signaling pathway in cancer cells and suppresses antitumor immunity by passing signals downstream of PD-1. Here, we utilized the extra druggable pocket outside the previously identified SHP2 allosteric tunnel site by the (6,5 fused), 6 spirocyclic system. The optimized compound, JAB-3312, exhibited a SHP2 binding K_d of 0.37 nM, SHP2 enzymatic IC₅₀ of 1.9 nM, KYSE-520 antiproliferative IC₅₀ of 7.4 nM and p-ERK inhibitory IC₅₀ of 0.23 nM. For JAB-3312, an oral dose of 1.0 mg/kg QD was sufficient to achieve 95% TGI in KYSE-520 xenograft model of mouse. JAB-3312 was well-tolerated in animal models, and a close correlation was observed between the plasma concentration of JAB-3312 and the p-ERK inhibition in tumors. Currently, JAB-3312 is undergoing clinical trials as a potential anticancer agent.

JAB-3312, a Potent Allosteric SHP2 Inhibitor that Enhances the Efficacy of RTK/RAS/MAPK and PD-1 Blockade Therapies

Abstract:

Purpose: Recent advances have seen the development of targeted therapeutics against the RTK/RAS/MAPK pathway which, when aberrantly activated, drives malignant transformation of many cancer indications. However, efficacy of inhibitors targeting single molecules is dampened by pathway feedback activation and acquired drug resistance. We seek to evaluate the application of JAB-3312 (Sitneprotafib), a potent inhibitor of SHP2, in the RTK/RAS/MAPK pathway-targeted combination therapies. Furthermore, SHP2 plays a vital role in PD-1-mediated immunosuppression. Rational combination of JAB-3312 with PD-1 blocking therapies is also explored. Experimental Design: Biochemical and cellular assays were applied to evaluate the potency of JAB-3312 in SHP2 inhibition. Tumor cell lines, cell line- and patient-derived xenografts were used to test different combinations of JAB-3312 with KRASG12C, MEK, EGFR, and PD-1 inhibitors. Results: JAB-3312 produced potent in vitro inhibition of SHP2 activity and downstream ERK phosphorylation, with IC50s of 1.44 nM and 0.68 to 4.84 nM, respectively. When in combination, JAB-3312 significantly increased the anti-tumor activity of KRASG12C inhibitor glecirasib in naïve and resistant models. Combination of JAB-3312 with MEK inhibitors significantly delayed RTK signaling reactivation and enhanced tumor growth inhibition in KRAS-mutated cancer models. JAB-3312-osimertinib combination exhibited great efficacy in osimertinib-resistant non-small cell lung cancer models. Besides, JAB-3312 enhanced the efficacy of PD-1 blockade therapies by promoting anti-tumor microenvironment. Representative cases of patients with response to the combination therapies from two ongoing clinical trials (NCT05288205, NCT04720976) were reported. Conclusions: JAB-3312 in combination with RTK/RAS/MAPK or PD-1 blockage therapies is a promising strategy that warrants further clinical investigation.

Jacobio Pharma Secures €172 Million: Concerns Over Collaboration Behind Ailis’ Massive Investment Exposed!

On September 27, 2024, Jacobio Pharma (stock code: 1167.HK) attracted a lot of attention in the industry when it officially announced a major cooperation development - the successful acquisition of Shanghai Ellis Pharmaceutical Technology Co., LTD. (stock code: 688578.SH) received up to 172 million yuan in cooperation funds. This payment not only marks the depth and stability of the cooperation between the two parties, but also demonstrates the excellent strength and extensive influence of Gax in the field of innovative drug research and development. The composition of this cooperation is quite remarkable, including a down payment of 150 million yuan, which is a direct reflection of Ellis' high recognition and value of Gax's research and development results. In addition, there is also 22.79 million RMB as research and development cost compensation and other related payments, which will strongly support Gax's continued investment and innovation exploration in subsequent research and development projects. Looking back at the history of cooperation between the two parties, it all began with the signing of a landmark cooperation agreement on August 30, 2024.This initiative not only shows CAx's trust and respect for its partners, but also reflects its firm determination to promote the development of China and even the global medical and health cause. KRAS G12C inhibitor Golelexel, as a star drug in the field of tumor therapy in recent years, has won widespread praise worldwide for its unique mechanism of action and remarkable efficacy. The SHP2 inhibitor JAB-3312 is another effort of GaX in the field of precision medicine, and its precision strike ability for specific targets has brought new hope to many patients with refractory diseases. The introduction of these two drugs will undoubtedly inject new vitality into Ellis' product line and further consolidate its leading position in the pharmaceutical market. It is worth noting that this cooperation not only reflects the depth of cooperation between the two sides in the field of drug research and development, but also indicates that China's pharmaceutical industry is gradually moving toward a new stage of internationalization and high-end. As the global pharmaceutical market continues to integrate and competition intensifies, Chinese pharmaceutical companies are enhancing their core competitiveness by strengthening international cooperation, introducing advanced technology and management experience. The cooperation between Gax and Ellis has undoubtedly set a new benchmark for the internationalization of China's pharmaceutical industry.
