(Coherus, Nasdaq: CHRS), today announced data from three immuno-oncology pipeline programs at the 38th Annual Meeting of SITC taking place November 1 - 5, 2023 at the San Diego Convention Center in San Diego, CA. Preclinical data presented support differentiated mechanisms of its next-generation immunotherapies potentially enabling the antitumor immune activation in more cancer patients and enhanced treatment outcomes. “These data presented at SITC highlight the complementary mechanisms that we have in our innovative immunotherapy portfolio, including anti-PD-1, anti-IL27 and anti-CCR8, and the promise of novel immuno-oncology treatment combinations that may overcome the challenging tumor microenvironment,” said Theresa LaVallee, Ph.D., Coherus’ chief development officer. “LOQTORZI™ is the first approved treatment option for patients with nasopharyngeal carcinoma (NPC), and we will continue to generate and use data to optimize our clinical development plans through the selection of additional tumor types and immuno-oncology combinations that can have the greatest impact on extending survival for cancer patients.” Casdozokitug (CHS-388, formerly SRF388), a first-in-class anti-IL-27 antibodyInterleukin (IL)-27 is an immunoregulatory cytokine involved in resolving inflammation and inhibiting anti-tumor immune responses. Blocking IL-27 with casdozokitug in clinical trials has led to monotherapy tumor growth inhibition and partial responses in patients with non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC) (NCT04374877) and ongoing trials are studying combinations with PD-1/PD-L1 pathway blockade in NSCLC and hepatocellular carcinoma (HCC). Data presented at SITC 2023 demonstrate IL-27-mediated gene expression, highlighting its critical role in immune suppressive mechanisms in the tumor microenvironment and importance as a new target for cancer treatment, as well as an opportunity to identify biomarkers that could determine patients most likely to respond to anti-IL-27 treatment. Abstract #1351: Identifying IL-27 dependent biomarkers in lymphocytes, NK cells, and myeloid cells in peripheral blood and the tumor microenvironmentDate and Time: Friday, November 3, 9 a.m.–7 p.m. Pacific Daylight Time (PDT)Location: Exhibit Halls A and B1 – San Diego Convention Center Poster presentation data are summarized as follows: In human immune cells from peripheral blood, IL-27 induces the expression of interferon (IFN)-stimulated genes, which are associated with drug resistance in cancerAlthough many known IFN-responsive genes were induced by both IFNs and IL-27 treatment, distinct gene expression was observed in different immune cell typesIL-27 and IFNs induce unique gene expression in different cell types, for example, GBP5 (guanylate-binding protein 5) and IRF1 (interferon regulatory factor 1), two interferon stimulated genes, are preferentially elevated by IL-27 in NK cells and CD8+ T cellsImmunohistochemistry (IHC) analysis of treatment-naïve NSCLC tumor samples showed that IL-27+ macrophages are co-localized with GBP5+ T-cell-rich areas in the TMEThese studies lend insights into the immune interplay between IFNs and IL-27 signaling across different immune cells and within the TME and ascertain the immunosuppressive role of IL-27 and may inform casdozo clinical development. CHS-114 (formerly SRF114), an anti-CCR8 antibodyCCR8 is a chemokine receptor predominantly expressed by tumor infiltrating Tregs that suppress the body’s natural anti-cancer immune response. Targeting CCR8 is a promising potential therapeutic strategy designed to deplete Tregs, reshape the tumor microenvironment and enhance anti-tumor immune response. CHS-114 is designed to selectively target human CCR8 and preferentially depletes CCR8+ Treg cells and not T effector (Teff) cells in tumors or normal tissue. Data presented demonstrate the role of CCR8+ Tregs as dominant immunosuppressive cells in the TME and highlight head and neck squamous cell carcinoma (HNSCC) as a promising tumor type in which CHS-114 could have anti-tumor activity as monotherapy or in combination with an anti-PD1 antibody. CHS-114 is currently being evaluated in a Phase 1 clinical trial (NCT05635643). Abstract #1354: Anti-CCR8 antibody SRF114 depletes tumor-infiltrating regulatory T cells in dissociated tumors from patients with head and neck squamous cell carcinomaDate and Time: Saturday, November 4, 9 a.m.–8:30 p.m. PDTLocation: Exhibit Halls A and B1 – San Diego Convention Center Poster presentation data are summarized as follows: Chemokine receptor 8 (CCR8) expression is highly enriched on intratumoral Tregs within the TME cells, particularly in HNSCCIn multiple model systems, CHS-114, a cytolytic antibody selective for CCR8, activates natural killer (NK) cells and specifically induces NK-mediated cytotoxicity against tumor-infiltrating CCR8+ Tregs and results in the expansion of effector CD8 T cellsEnhanced antitumor immunity is observed with combination of Anti-CCR8 and anti-PD-1 combination treatmentCHS-114, a CCR8-specific cytotoxicity-inducing antibody that preferentially depletes CCR8+ Treg cells and not T effector (Teff) cells, is currently being evaluated in a Phase 1 clinical trial (NCT05635643). LOQTORZI™ (toripalimab-tpzi), a next generation anti-PD-1 antibodyPD-L1 is a protein found on the surface of some cancer cells that can help evade the body’s immune system by suppressing T cell activation and inhibiting the T cell’s ability to kill cancer cells. LOQTORZI™ is an anti-PD-1 monoclonal antibody that blocks PD-L1 binding to the PD⁠-⁠1 receptor at a unique site with high affinity to activate antitumor immunity. Data presented compare mechanistic data for LOQTORZI™ to commercially available anti-PD-1 monoclonal antibodies and demonstrate higher expression of key immune system biomarkers with LOQTORZI™. Additionally, LOQTORZI™ in combination with chemotherapy shows enhanced clinical efficacy irrespective of PD-L1 status across multiple tumor types in post hoc analyses of 3 randomized controlled clinical trials in NPC, NSCLC and esophageal squamous-cell carcinoma (ESCC). LOQTORZI™ (toripalimab-tpzi) was recently approved by the U.S. Food and Drug Administration (FDA) for metastatic or recurrent NPC as first-line treatment in combination with chemotherapy or as second- or greater-line monotherapy treatment.

- Preclinical data identify SHP-1 as a downstream effector of GDF-15-mediated inhibition of T cell adhesion, further elucidating mechanistic details of GDF-15’s role in immunotherapy resistance. - Combination of visugromab and bispecific T-cell engager significantly increased the number of intratumoral T cells in a mouse tumor model, providing a strong rationale to further investigate this combination approach. - Preclinical data continue to expand the potential of GDF-15 neutralizing therapy, supporting its role as a critical component for treatment success in a broad range of anti-cancer regimens. MUNICH--(BUSINESS WIRE)-- CatalYm today announced the presentation of two preclinical data sets expanding the mechanistic understanding and clinical application of its lead anti-GDF-15 antibody candidate, visugromab, at the upcoming Society for Immunotherapy of Cancer (SITC) 2023 Annual Meeting in San Diego, USA. The findings will be presented in two poster sessions on Friday, November 3rd, and Saturday, November 4th, and provide further clarification on GDF-15-mediated inhibition of T cell infiltration and highlight the potential of combining visugromab with bispecific T-cell engagers as a novel approach in cancer therapy. Visugromab is currently evaluated in a broad Phase 2 program in combination with anti-PD-1 treatment in multiple solid tumor indications. “We are advancing our understanding of the underlying molecular mechanisms that are the foundation for GDF-15’s central role in tumor resistance to immunotherapy and visugromab’s potential to reinstate anti-tumor activity and enhance responses,” said Dr. Christine Schuberth-Wagner, Chief Scientific Officer at CatalYm. “The new data for the combination of visugromab with bispecific T-cell engagers provide strong scientific support for a synergistic effect in this novel therapeutic setting. We will further investigate this combination, which could extend durability and improve outcomes for a broad range of cancer patients with high medical need.” Poster Presentation Identifying SHP-1 as Central Mediator of GDF-15-related T Cell Adhesion Inhibition The first data set further expands understanding of visugromab’s mechanism of action and the underlying pathways involved in the development of GDF-15-mediated therapy resistance in cancer cells. When investigating the involvement of additional cell adhesion pathway components downstream of GDF-15, SHP-1 was identified as a central mediator of GDF-15-related inhibition of T cell adhesion. SHP-1 is an intracellular tyrosine phosphatase known as a negative regulator of antigen-dependent activation and proliferation of T cells. Inhibition of SHP-1 resulted in abrogation of GDF-15’s inhibitory effect. The researchers confirmed that GDF-15 via SHP-1 inhibits the phosphorylation of ZAP-70, another intracellular tyrosine kinase involved in LFA-1 inside-out activation and T cell receptor signaling. These data connect SHP-1 as a downstream effector to the recently published GDF-15-mediated reduction of high-affinity LFA-1 conformation, leading to impaired endothelial adhesion and transmigration of T cells toward the tumor site. Poster Presentation Details Title: SHP-1 is a central mediator of GDF-15 mediated adhesion inhibition in T cells Presenter: Dr. Christine Schuberth-Wagner Abstract number: 1049 Date and time: Friday, Nov 3rd, 5:00-6:30pm PDT Poster Presentation on Visugromab/T-Cell Engager Combination The second data set supports the expansion of visugromab’s application to combinations with immune cell-engaging therapies, underlining its potential to be a critical component for treatment success in a broad range of anti-cancer regimens. The preclinical analyses investigated a new combination of visugromab with a bispecific T-cell engager (tebentafusp). Anti-tumor activity of bispecific T-cell engagers is dependent on infiltration of effector T cells into the tumor microenvironment. In vivo analyses in a mouse tumor model demonstrated that the combination with visugromab significantly increased the number of intratumoral T cells compared with tebentafusp alone. This indicates a direct positive impact of visugromab’s infiltration-enhancing activity on the anti-tumor activity of bispecific T-cell engaging treatments and provides a strong rationale to further investigate this therapeutic concept. Poster Presentation Details Title: GDF-15 neutralizing antibody visugromab increases intratumoral immune cell infiltration to support bispecific T-cell engagers Presenter: Dr. Christine Schuberth-Wagner Abstract number: 1196 Date and time: Saturday, Nov 4th, 7:00-8:30pm PDT CatalYm is investigating its GDF-15-neutralizing antibody visugromab in a broad Phase 2 clinical program, the GDFather (GDF-15 Antibody-mediaTed Human Effector Cell Relocation) trials, in combination with the anti-PD-1 inhibitor nivolumab in patients with advanced solid tumors. First interim data from the Phase 2 (NCT04725474) trial continue to demonstrate a very good safety and tolerability pro promising early responses in major cancer indications, including non-small cell lung cancer (NSCLC), bladder cancer and hepatocellular carcinoma (HCC). In addition, CatalYm recently announced an exploratory Phase 2 study, GDFather-NEO (NCT06059547), evaluating visugromab in combination with neoadjuvant immunotherapy in first-line muscle-invasive bladder cancer. About Visugromab (CTL-002) Visugromab is a monoclonal antibody that neutralizes the tumor-derived Growth Differentiation Factor-15 (GDF-15), a locally acting immunosuppressant fostering immunotherapy resistance. Neutralizing GDF-15 with visugromab reverses key cancer resistance mechanisms to reinstate an efficient anti-tumor response by reenabling immune cell activation and tumor infiltration. Visugromab has already demonstrated a good safety pro potent and durable anti-tumor efficacy in combination with anti-PD-1 treatment in advanced cancer patients The antibody is currently being investigated in ongoing Phase 2 studies in multiple solid tumor indications. About CatalYm CatalYm has identified GDF-15 as a key cancer therapy resistance mechanism and is developing a safe and efficacious immune therapy for solid tumors. GDF-15, an immunosuppressant important for feto-maternal tolerance, is hijacked by cancer cells to evade immune system attack. Visugromab, CatalYm’s lead antibody, has demonstrated durable anti-tumor efficacy with long-lasting objective responses in relapsed and refractory metastatic solid tumor patients in combination with anti-PD-1. CatalYm is now advancing to Phase 2b studies to confirm visugromab as a new class of cancer immunotherapy in a broad range of anti-cancer regimens.

— Data demonstrate preclinical potent T cell activation and differentiated mechanism of action and enhanced clinical efficacy irrespective of PD-L1 status when administered in combination with chemotherapy — — Toripalimab demonstrated twelve-fold higher binding affinity to PD-1 compared to pembrolizumab — — In vitro studies show significantly higher activation of T cells compared to pembrolizumab in multiple assay systems — REDWOOD CITY, Calif., Oct. 14, 2023 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (“Coherus”, Nasdaq: CHRS), today announced a presentation of toripalimab data at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics being held October 11-15, 2023 at the Hynes Convention Center in Boston. PD-L1, a protein found on the surface of some cancer cells, suppresses T cell activation and inhibits the ability of the body’s immune system to kill cancer cells. Toripalimab is an anti-PD-1 monoclonal antibody that binds with high affinity to a unique site on PD-1, thereby blocking the interaction of PD-1 and PD-L1. Preclinical mechanistic data demonstrate statistically significantly higher activation of T cells and higher expression of key immune system activators with toripalimab compared to pembrolizumab, clinically a widely used anti-PD-1 monoclonal antibody for the treatment of cancer patients. These data may provide a mechanistic explanation for the improvements in overall survival irrespective of PD-L1 expression levels observed in clinical trials in multiple tumor types evaluating toripalimab in combination with chemotherapy. A biologics license application (BLA) for toripalimab in combination with chemotherapy as treatment for recurrent or metastatic nasopharyngeal carcinoma (NPC) is currently under review by the U.S. Food and Drug Administration (FDA). “PD-1 inhibition has been a significant advancement in cancer treatment across tumor types but better treatments are needed to increase response rates and drive improved outcomes for patients. These data support toripalimab as a next-generation PD-1 inhibitor that, in combination with chemotherapy, may have greater antitumor activity in less inflamed tumors than more commonly used PD-1 inhibitors in certain cancers due to its unique binding properties,” said Theresa LaVallee, Ph.D., Coherus’ chief development officer. “We look forward to delivering this important new treatment option to patients, first in NPC, if approved, and continuing to evaluate its efficacy in combination with chemotherapy in multiple cancer types and in combination with novel I-O agents.” Poster presentation data are summarized as follows: Toripalimab in combination with chemotherapy significantly improved overall survival irrespective of PD-L1 status in post hoc analyses of 3 randomized controlled clinical trials, including in NPC, non-small cell lung cancer (NSCLC) and esophageal squamous-cell carcinoma (ESCC)Toripalimab exhibits a 12-fold higher binding affinity for PD-1 compared to pembrolizumab that is driven by a slow-off rateToripalimab is more potent than pembrolizumab in enhancing levels of Th1 cytokines and cytotoxicity in human peripheral blood mononuclear cells (PBMCs)In comparison to pembrolizumab, binding of toripalimab to PD-1 induced low levels of SHP1 and SHP2 recruitment, thereby minimizing a key process of T cell suppressionToripalimab induced and elevated IFN-y gene signature in NSCLC dissociated tumor cells with different kinetics and intensity compared to pembrolizumab Poster presentation details: Poster Number C069: Toripalimab, an anti-PD-1 antibody that demonstrates potent T cell activation and enhanced clinical efficacy irrespective of PD-L1 statusSession: Poster Session CDate and time: Saturday, October 14, 12:30 pm-4:00 pm EDTLocation: Level 2, Exhibit Hall D About toripalimabToripalimab is a next-generation anti-PD-1 monoclonal antibody that blocks PD-L1 binding to the PD⁠-⁠1 receptor at a unique site with high affinity and activates antitumor immunity demonstrating improvement in the overall survival of cancer patients in several tumor types.
