Phanes Therapeutics announces first patient dosed in clinical study of mavrostobart (PT199) in combination with chemotherapy
SAN DIEGO, May 27, 2025 /PRNewswire/ — Phanes Therapeutics, Inc. (Phanes), a clinical stage biotech company focused on innovative drug discovery and development in oncology, announced today that the first patient has been dosed in the clinical study of mavrostobart (PT199) in combination with chemotherapy. Mavrostobart is an anti-CD73 monoclonal antibody with a differentiated mechanism of action and is designed to counter the adenosine-mediated immunosuppressive tumor microenvironment (TME). Mavrostobart fully inhibits the enzyme activities of both soluble and membrane-bound CD73, unlike several other anti-CD73 antibodies which exhibit incomplete inhibition. Moreover, at higher concentrations, no loss of inhibition or 'hook effect' is observed with mavrostobart. Hence, mavrostobart addresses the limitations of current CD73 inhibitors and is expected to increase antitumor immune activation, and potentially offer a new treatment option for cancer patients. The multi-center Phase I/II clinical trial of mavrostobart (NCT05431270), known as the MORNINGSTAR study, is currently evaluating the safety, tolerability, pharmacokinetics and preliminary efficacy of mavrostobart alone and in combination with a PD-1 Inhibitor or chemotherapy. A Phase I clinical trial of mavrostobart is also ongoing in China (CTR20242381). ABOUT PHANES THERAPEUTICS Phanes Therapeutics, Inc. is a clinical stage biotech company focused on innovative drug discovery and development in oncology. Currently, it is conducting three Phase I/II clinical trials, including the MORNINGSTAR study with its best-in-class monoclonal antibody (mAb) program, mavrostobart (PT199), the TWINPEAK study with spevatamig (PT886) and the SKYBRIDGE study with peluntamig (PT217). Both spevatamig and peluntamig are first-in-class bispecific antibodies and have been granted orphan drug designations as well as Fast Track designations by the FDA. The company has built a strong pipeline by leveraging its proprietary technology platforms: PACbody®, SPECpair® and ATACCbody® to develop novel biologics that address high unmet medical needs in cancer.

Great Novel Therapeutics Biotech & Medicals Corporation (GNTbm) Presented Preclinical Data on GNTnm-38, an Novel Epigenetic Immune Activator, at the 2025 ASCO Annual Meeting
TAIPEI, May 22, 2025 /PRNewswire/ -- GNTbm (stock code: 7427, Taiwan) announced the preclinical data on GNTbm-38, an novel epigenetic immune activator for cancer immunotherapy. GNTbm-38 was presented as posters at the 2025 American Association of Clinical Oncology (ASCO) Annual Meeting, which is held in Chicago, USA, from May 30 to Jun 04, 2025. Abstract: 2574 Title: Preclinical development of GNTbm-38, a novel class I histone deacetylase inhibitor, while combined with anti-VEGFR TKI or anti-PD-1 Ab: Assessment of immune activation and immune memory in cancer immunotherapy. Session Date/Time: 6/2/2025, 1:30 PM-4:30 PM CT Poster Board Number: 221 At present, there is no ICI-based drug combination for the treatment of advanced MSS colorectal cancer, which is a cold tumor. Studies have shown that epigenetic regulators such as class I HDAC inhibitors are an emerging and important drug component for combination therapy that can greatly increase the anti-cancer benefits of cancer immunotherapy. Therefore, rational drug combinations, containing class I HDACi, may provide opportunities in cancer immunotherapy. GNTbm-38 is a new drug candidate independently developed by GNTbm. GNTbm-38 acts as a TME reprogramming regulator in immunotherapy. When combined with TKI, GNTbm-38 significantly improved tumor response rate and survival rate through synergistic effect by normalizing tumor vessels, increasing tumor antigen presentation, increasing activated CD8+ T cell infiltration into tumors, inducing memory T cell persistence, and inhibiting mobilization of immunosuppressive cells into tumors. On the other hand, treatment with GNTbm-38 plus anti-PD-1 antibody in the CT-26 model showed greatly improved tumor response rate and survival rate with a strong synergistic effect. Furthermore, in B-hPD-1/hPD-L1 mice (humanized model) subcutaneously injected with B-hPD-L1 CT-26 cells, treatment of pembrolizumab and GNTbm-38 resulted in a 46.5% inhibition on tumor growth. Therefore, our data provided a strong rationale to explore the combination of GNTbm-38 with anti-VEGF TKI with or without ICI. From these data GNTm-38 has been shown to display powerful induction of immune activation and immune memory in combination therapy with TKI/ICI against colon CT-26 cold tumor. Based on the in vitro, in vivo and preclinical studies, these data show that GNTbm-38 exhibits markedly superior pharmacokinetics, tolerability, and efficacy in animal models. It is expected to complete the US IND application by the end of 2025 and enter the clinical study. About GNTbm-38 GNTbm-38 is a new chemical entity with potential as a pivotal drug component of a new generation of cancer immunotherapy 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 confirm that it has very outstanding anti-cancer activity in tumor microenvironment. GNTbm-38 is an oral drug with dual effects of epigenetic regulation of gene expression and immune activation, which is unique when compared to the mechanism of other epigenetic drugs. GNTbm-38 can remodel the tumor microenvironment (TME) through a unique epigenetic regulatory mechanism, including the cell composition and gene expression that affect the TME, so that "cold tumors" can be transformed into "hot tumors", which can attract CTL to infiltrate into the TME, and 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-38 monotherapy can be used in the treatment of hematological tumors, and GNTbm-38 can also be combined with a unique multi-kinase inhibitor or immune checkpoint inhibitor for treatment of a variety of solid tumors, mainly through a unique anti-cancer immune-regulating mechanism to achieve anti-cancer treatment goals. About GNTbm GNTbm (stock code: 7427, Taiwan) is a company that has conducted clinical trials and developed a new drug against advanced breast cancer on the market in Taiwan. The GNTbm R&D team has the ability to independently develop new drugs, and has multiple anti-cancer drug candidates with global development rights, with the goal of meeting the unmet clinical needs of patients with advanced cancers. GNTbm mainly focuses on the development of drugs with innovative mechanisms for the new generation of cancer immunotherapy, conducts clinical validation, and hopes to successfully provide novel immunotherapy with excellent efficacy and safety for varieties of cancer indications, to fulfil the unmet medical needs of patients around the world and improve the quality of life of patients.
