HAYWARD, Calif.--( BUSINESS WIRE )--Arcus Biosciences, Inc. (NYSE:RCUS), a clinical-stage, global biopharmaceutical company focused on developing differentiated molecules and combination therapies for patients with cancer, today reported financial results for the third quarter ended September 30, 2024, and provided a pipeline update on its clinical-stage investigational molecules — targeting TIGIT, HIF-2a, CD73, the A2a/A2b receptors, CD-39, AXL and PD-1 — across multiple common cancers. “ Through the course of this year, we have presented multiple compelling datasets at medical conferences that we believe have de-risked several programs and support potential best-in-class profiles for our molecules, including our HIF-2a inhibitor casdatifan in ccRCC and our Fc-silent anti-TIGIT antibody domvanalimab in lung and upper gastrointestinal cancers,” said Terry Rosen, Ph.D., chief executive officer of Arcus. “ Meanwhile, in addition to our rapidly approaching first Phase 3 readout for domvanalimab in gastric cancer, we are aggressively pursuing our development plan for casdatifan, including in the IO-naive ccRCC setting in collaboration with AstraZeneca, and in the post-IO setting with the initiation of our Phase 3 PEAK-1 study in the first half of next year.” Corporate Updates: In October 2024, Arcus announced a clinical collaboration with AstraZeneca to evaluate casdatifan in combination with volrustomig, AstraZeneca’s investigational PD-1/CTLA-4 bispecific antibody, in IO-naive patients with ccRCC. AstraZeneca will operationalize the study. This is the second clinical collaboration between Arcus and AstraZeneca. Gilead retains the right to opt in to the development and commercialization for casdatifan after delivery of a qualifying data package. Pipeline Highlights: Casdatifan (HIF-2a inhibitor) Casdatifan Updates: First clinical data from the casdatifan 100mg and 50mg expansion cohorts of ARC-20, a Phase 1/1b study in metastatic ccRCC, were presented in an oral plenary session at the 2024 EORTC-NCI-AACR Symposium in October. Observations from the 100mg daily expansion cohort included: An objective response rate (ORR) of 34% (2 responses are pending confirmation; 25% confirmed ORR), a low rate of primary progression of 19% and a high disease control rate of 81%. The median progression-free survival (PFS) had not been reached at the time of the data cutoff. Together, these data support the potential for casdatifan to be a best-in-class HIF-2a inhibitor for the treatment of ccRCC. In the third quarter, Arcus had a successful Type B meeting with the U.S. Federal Drug Administration (FDA) to discuss its first Phase 3 study for casdatifan, PEAK-1, which will evaluate casdatifan in combination with cabozantinib versus cabozantinib in post-IO patients with ccRCC. Arcus is moving rapidly toward the initiation of PEAK-1 in the first half of 2025. Upcoming Casdatifan Milestones: Multiple expansion cohorts of ARC-20 evaluating casdatifan in ccRCC as a monotherapy and in combination with cabozantinib in ccRCC are underway with additional data presentations expected in the next 12 months. 100mg (50mg twice daily (BID), capsules) and 50mg expansion cohorts: Updated data, including median PFS, are expected to be presented in the first quarter of 2025. 150mg and 100mg (once daily (QD), tablets) expansion cohorts: Initial data are expected to be presented in 2025. 100mg of casdatifan plus cabozantinib: Safety data are expected to be presented in 2025. Domvanalimab (Fc-silent anti-TIGIT antibody) plus Zimberelimab (anti-PD-1 antibody) Domvanalimab-Zimberelimab Updates: Data from Part 1 of ARC-10, a randomized study evaluating domvanalimab plus zimberelimab in PD-L-1 high NSCLC are being presented at the SITC Annual Meeting in November. Domvanalimab plus zimberelimab was associated with greater PFS, overall survival, and objective response rate compared with zimberelimab or chemotherapy. A 36% reduction in risk of death (hazard ratio [HR]=0.64) was observed for domvanalimab plus zimberelimab compared to that of zimberelimab alone. Zimberelimab reached a median overall survival of 2 years, and the median overall survival for domvanalimab plus zimberelimab was not reached. Treatment-related adverse events leading to treatment discontinuation were low (10.5%) for the combination of domvanalimab and zimberelimab. Data from an investigator-sponsored trial evaluating domvanalimab plus zimberelimab in anti-PD-(L)1 refractory hepatocellular carcinoma will be presented in an oral session at the SITC Annual Meeting. Upcoming Domvanalimab-Zimberelimab Milestones: Overall survival data from the Phase 2 EDGE-Gastric study, evaluating domvanalimab plus zimberelimab and chemotherapy in upper gastrointestinal (GI) adenocarcinomas, are expected to be presented in 2025. CD73-Adenosine Axis: Quemliclustat (small-molecule CD73 inhibitor) and Etrumadenant (A2a/A2b receptor antagonist) Quemliclustat Arcus has initiated PRISM-1, a Phase 3 trial of quemliclustat combined with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel in pancreatic cancer. Etrumadenant Biomarker data from cohort B of ARC-9, a randomized Phase 1b/2 study evaluating etrumadenant plus zimberelimab, FOLFOX chemotherapy and bevacizumab (EZFB) versus regorafenib in third-line metastatic colorectal cancer (mCRC), are being presented at SITC in November. Early Clinical Programs Evaluation of AB801, a potent and highly selective small-molecule AXL inhibitor, in the dose-escalation phase of a Phase 1/1b study in patients is ongoing. Arcus anticipates advancing this molecule into expansion cohorts in NSCLC in early 2025. Financial Results for Third Quarter 2024: Cash, Cash Equivalents and Marketable Securities were $1.1 billion as of September 30, 2024, compared to $866 million as of December 31, 2023. The increase during the period is primarily due to the receipt of $320 million in cash from Gilead for their January 2024 equity investment, the receipt of the $100 million option continuation payment from Gilead in July 2024 and proceeds from our $50 million term loan, partially offset by the use of cash in research and development activities. We believe our cash, cash equivalents and marketable securities on-hand will be sufficient to fund operations into mid-2027. Cash, cash equivalents and marketable securities are expected to be between $950 million and $985 million at the end of 2024. Revenues were $48 million for the third quarter 2024, compared to $32 million for the same period in 2023. In the third quarter 2024, Arcus recognized $41 million in license and development services revenue related to the advancement of programs and Taiho's exercise of its option for the license of quemliclustat for the Taiho Territory of $15 million, as well as $7 million in other collaboration revenue primarily related to Gilead’s ongoing rights to access Arcus’s research and development pipeline in accordance with the Gilead collaboration agreement. Research and Development (R&D) Expenses were $123 million for the third quarter 2024, compared to $82 million for the same period in 2023. The net increase of $41 million was primarily driven by higher clinical trial and headcount-related costs associated with our late-stage development program activities. Non-cash stock-based compensation expense was $9 million for the third quarter 2024, compared to $8 million for the same period in 2023. For the third quarter 2024 and 2023, Arcus recognized gross reimbursements of $37 million and $33 million, respectively, for shared expenses from its collaborations, primarily the Gilead collaboration. R&D expense by quarter may fluctuate due to the timing of clinical manufacturing and standard-of-care therapeutic purchases with a corresponding impact on reimbursements. General and Administrative (G&A) Expenses were flat for the third quarter 2024, compared to the same period in 2023. Non-cash stock-based compensation expense was $10 million for each of the third quarter 2024 and 2023. Net Loss was $92 million for the third quarter 2024, compared to $71 million for the same period in 2023.

HAYWARD, CA, USA I November 05, 2024 I Arcus Biosciences, Inc. (NYSE:RCUS), a clinical-stage, global biopharmaceutical company focused on developing differentiated molecules and combination therapies for patients with cancer, today announced results from Part 1 of ARC-10, a randomized, open-label, three-arm study evaluating domvanalimab, an Fc-silent anti-TIGIT monoclonal antibody, plus zimberelimab, an anti-PD-1 monoclonal antibody, (DZ) versus zimberelimab (Z) or chemotherapy in patients with front-line locally advanced or metastatic squamous or non-squamous non-small cell lung cancer (NSCLC) with PD-L1 tumor proportion score (TPS) ≥50% without the presence of any tumor genomic aberration or driver mutation for which a targeted therapy is approved. This study was conducted in partnership with Gilead Sciences. These results will be presented on November 8 in a late-breaking poster session at the Society for Immunotherapy of Cancer (SITC) 2024 Annual Meeting by Melissa L. Johnson, M.D., Director of the Lung Cancer Research Program, Sarah Cannon Research Institute, and investigator for the ARC-10 study. “Domvanalimab plus zimberelimab demonstrated a meaningful improvement in overall survival compared to zimberelimab alone, with a 36% reduction in risk of death and a median overall survival that will exceed two years,” said Melissa L. Johnson, M.D. “These data provide further evidence that co-inhibiting the TIGIT and PD-1 pathways may result in a greater therapeutic benefit over inhibition of the PD-1 pathway alone.” “These are the first results demonstrating an improvement in overall survival reported for domvanalimab and zimberelimab,” said Dimitry Nuyten, M.D., Ph.D., chief medical officer of Arcus. “They add to the growing body of evidence that domvanalimab, an Fc-silent anti-TIGIT antibody, may have a differentiated efficacy, safety and tolerability profile relative to published data from studies with Fc-enabled anti-TIGIT antibodies.” At the time of data cutoff (DCO, May 17, 2024), 98 patients were randomized and 95 received treatment in Part 1 of the study. The median follow-up was 24.5 months, and as of the DCO, 22 patients remained on treatment (DZ, n=11; Z, n=10; chemo, n=1). Patient baseline demographics were generally balanced across the arms, with a slight imbalance of more patients with adenocarcinoma, ECOG status 0, and brain metastasis favoring the chemotherapy arm. A summary of efficacy results is below. DZ and Z were generally well tolerated with no new safety concerns at the time of DCO. Treatment-related adverse events (TRAEs) leading to treatment discontinuation were higher for chemotherapy (23.5%) than for DZ (10.5%) and Z (7.5%). Infusion-related reactions were low (DZ, 7.9%; Z, 2.5%; chemotherapy, 0%). Grade ≥3 TRAEs were higher for chemotherapy (47.1%) than for DZ (21.1%) or Z (15.0%). TRAEs leading to death were lower for DZ (2.6%; n=1 sudden death) vs Z (10.0%; n=1 each sudden death, acute kidney injury, acute myocardial infarction, intestinal perforation) or chemotherapy (11.8%; n=1 each febrile neutropenia, ischemic stroke).

About the ARC-10 Study ARC-10 was initially initiated and conducted as a randomized Phase 3 trial; the protocol was subsequently amended to evaluate domvanalimab plus zimberelimab versus pembrolizumab (part 2). Part 1 of the ARC-10 study is a multicenter, randomized, open-label study for patients with front-line locally advanced or metastatic squamous or non-squamous NSCLC with PD-L1 TPS ≥50% without the presence of any tumor genomic aberration or driver mutation for which a targeted therapy is approved. The study randomized patients 2:2:1 across the three study arms to receive every three weeks: (1) 15 mg/kg of domvanalimab plus 360 mg/kg of zimberelimab, (2) 360 mg/kg of zimberelimab or (3) platinum doublet chemotherapy in countries where anti-PD-(L)1 monotherapy was not yet standard of care. The primary endpoint was PFS per Response Evaluation Criteria in Solid Tumors (RECIST 1.1). The secondary endpoints were OS, confirmed ORR and safety. About Domvanalimab Domvanalimab is the most clinically advanced Fc-silent investigational monoclonal antibody that was specifically designed with Fc-silent properties to block and bind to the T-cell immunoreceptor with Ig and ITIM domains (TIGIT), a checkpoint receptor on immune cells that acts as a brake on the anticancer immune response. By binding to TIGIT with Fc-silent properties, domvanalimab is believed to work by freeing up immune-activating pathways and activating immune cells to attack and kill cancer cells without depleting the peripheral regulatory T cells important in avoiding immune-related toxicity. Combined inhibition of both TIGIT and programmed cell death protein-1 (PD-1) is believed to significantly enhance immune cell activation, as these checkpoint receptors play distinct, complementary roles in anti-tumor activity. Domvanalimab is being evaluated in combination with anti-PD-1 monoclonal antibodies, including zimberelimab, as well as other investigational cancer immunotherapies and A2a/A2b adenosine receptor antagonist etrumadenant, in multiple ongoing and planned early and late-stage clinical studies in various tumor types. About Zimberelimab Zimberelimab is an anti-programmed cell death protein-1 (PD-1) monoclonal antibody that binds PD-1, with the goal of restoring the anti-tumor activity of T cells. Zimberelimab has demonstrated high affinity, selectivity and potency in various tumor types. Zimberelimab is being evaluated in the U.S. and globally as a foundational anti-PD-1 treatment option in multiple ongoing and planned early and late-stage clinical studies in combination with other immunotherapies, including investigational Fc-silent anti-TIGIT monoclonal antibody domvanalimab and A2a/A2b adenosine receptor antagonist etrumadenant. Guangzhou Gloria Biosciences Co. Ltd., which holds commercialization rights for zimberelimab in greater China, has obtained approval for zimberelimab for the treatment of recurrent or metastatic cervical cancer and for relapsed or refractory classical Hodgkin’s lymphoma. Zimberelimab is not approved for any use in the U.S. or other regions outside of China. Gloria conducts its development and commercialization activities independent of Arcus and Gilead. Domvanalimab and zimberelimab are investigational molecules. Arcus and Gilead have not received approval from any regulatory authority for any commercial use globally, and their safety and efficacy for the treatment of lung cancer have not been established.
