•PEAK-1, the initial Phase 3 study evaluating casdatifan in combination with cabozantinib, is expected to begin in the first half of 2025
•Patient enrollment has completed for the Phase 3 study STAR-221 (upper gastrointestinal (GI) cancers) for domvanalimab plus zimberelimab and chemotherapy
•Arcus is well-positioned to advance its full pipeline with $1.0 billion in cash, cash equivalents and marketable securities and runway into 2027
•Conference call today at 2:00 PM PT / 5:00 PM ET
HAYWARD, Calif. – (BUSINESS WIRE) – August 8, 2024 – Arcus Biosciences, Inc. (NYSE:RCUS), a clinical-stage, global biopharmaceutical company focused on developing differentiated molecules and combination therapies for people with cancer, today reported financial results for the second quarter ended June 30, 2024, and provided a pipeline update on its clinical-stage investigational molecules – targeting TIGIT, the adenosine axis (CD73 and A2a/A2b receptors), HIF-2a, AXL and PD-1 – across multiple common cancers.
“Our upcoming presentation of efficacy and safety data for casdatifan will demonstrate that it has the potential to be the best-in-class HIF-2a inhibitor,” said Terry Rosen, Ph.D., chief executive officer of Arcus. “We are pursuing a broad development program in both first- and second-line settings, as well as differentiated combinations, to maximize the opportunity for casdatifan in ccRCC. Meanwhile, the accumulating data continue to enhance our confidence that our Fc-silent anti-TIGIT antibody, domvanalimab, has the potential for an improved safety profile over that of Fc-enabled antibodies, particularly when combined with chemotherapy, which may also result in an efficacy advantage for domvanalimab. With STAR-221 enrollment completed, we are looking forward to our first Phase 3 data readout.”
Corporate Updates:
•In July 2024, Taiho Pharmaceutical (Taiho) exercised its option for quemliclustat, an investigational small molecule CD73 inhibitor, in Japan and certain other territories in Asia (excluding mainland China). As a result of this option exercise, Taiho will operationalize the Phase 3 PRISM-1 study evaluating quemliclustat in pancreatic cancer in Japan, and Arcus will receive an opt-in payment and is eligible to receive near-term milestone payments.
Pipeline Highlights:
Casdatifan (HIF-2a inhibitor)
•Multiple expansion cohorts evaluating casdatifan in clear cell renal cell carcinoma (ccRCC) are underway, with several data presentations expected in the next 18 months. Each cohort is enrolling approximately 30 patients.
◦ARC-20: Phase 1/1b study evaluating casdatifan as a monotherapy and in combination with other agents:
▪100 mg daily expansion cohort in 2L+ ccRCC: ORR data are expected to be presented in the fourth quarter of 2024.
▪50 mg and 150 mg expansion cohorts in 2L+ ccRCC: Enrollment has been completed for both cohorts and data are expected to be presented in 2025.
▪An expansion cohort evaluating casdatifan in combination with cabozantinib in 2L+ ccRCC is also enrolling.
•Following FDA feedback later this year, Arcus plans to initiate its first Phase 3 study, PEAK-1, evaluating casdatifan in combination with cabozantinib versus cabozantinib monotherapy in patients with metastatic ccRCC who have previously received anti-PD-1 therapy, in the first half of 2025.


•Arcus is in advanced stages of planning with a clinical collaboration partner to evaluate casdatifan in a potential first-in-class combination regimen for first-line metastatic ccRCC.
Domvanalimab (Fc-silent anti-TIGIT antibody) plus Zimberelimab (anti-PD-1 antibody)
Domvanalimab-Zimberelimab Updates:
•Updated data presented at the ASCO Annual Meeting from Arm A1 of the Phase 2 EDGE-Gastric study showed 12.9 months median progression-free survival (PFS) for domvanalimab plus zimberelimab and chemotherapy in first-line upper GI adenocarcinomas, which exceeded historical benchmarks for anti-PD-1 plus chemotherapy.
◦The EDGE-Gastric study is evaluating the same regimen in the same setting as the STAR-221 Phase 3 study.
•STAR-221, a Phase 3 study evaluating domvanalimab plus zimberelimab and chemotherapy in PD-L1 all-comer first-line metastatic upper GI adenocarcinomas, completed enrollment in June.
•STAR-121, a Phase 3 study evaluating domvanalimab plus zimberelimab and chemotherapy in PD-L1 all-comer first-line metastatic non-small cell lung cancer (NSCLC), is expected to complete enrollment in 2024.
Upcoming Domvanalimab-Zimberelimab Milestones:
•Overall survival (OS) and PFS data from previously enrolled patients in Part 1 of the Phase 3 ARC-10 study, evaluating domvanalimab plus zimberelimab versus zimberelimab versus chemotherapy in first-line PD-L1-high NSCLC, are expected to be presented by the end of 2024.
•OS data from the Phase 2 EDGE-Gastric study, evaluating domvanalimab plus zimberelimab and chemotherapy in upper GI adenocarcinomas, are expected to be presented in 2025.
CD73-Adenosine Axis: Etrumadenant (A2a/A2b receptor antagonist) and Quemliclustat (small-molecule CD73 inhibitor)
Etrumadenant
•Cohort B data from 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), were presented at ASCO in June.
◦Results showed 19.7 months median OS for the EZFB arm, and EZFB significantly reduced the risk of death by 63% and risk of disease progression by 73% compared to regorafenib. This is the longest median OS reported in third-line mCRC to date in a randomized trial.
◦Biomarker data from this study are expected to be presented at a scientific conference in the second half of 2024.
•Based on these encouraging results, Arcus and Gilead are determining next steps for the development of etrumadenant in mCRC.
Quemliclustat
•Initiation of a Phase 3 trial, PRISM-1, of quemliclustat combined with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel in pancreatic cancer is expected to begin by early 2025.
•Taiho exercised its option for an exclusive license to quemliclustat in Japan and certain territories in Asia and will operationalize PRISM-1 in Japan.
Early Clinical Programs
•Dose escalation for AB801, a potent and highly selective small-molecule AXL inhibitor, continues. Arcus anticipates advancing this molecule into expansion cohorts in NSCLC in early 2025.
Financial Results for Second Quarter 2024:
•Cash, Cash Equivalents and Marketable Securities were $1.0 billion as of June 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, 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 2027. Cash, cash equivalents and marketable securities are expected to be between $885 million and $925 million at the end of 2024.


•Revenues were $39 million for the second quarter 2024, compared to $29 million for the same period in 2023. In the second quarter 2024, Arcus recognized $28 million in license and development services revenue related to the advancement of programs, as well as $11 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 $115 million for the second quarter 2024, compared to $84 million for the same period in 2023. The net increase of $31 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 $10 million for the second quarter 2024, compared to $9 million for the same period in 2023. For the second quarter 2024 and 2023, Arcus recognized gross reimbursements of $40 million and $44 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 $30 million for the second quarter 2024, compared to $28 million for the same period in 2023. The increase was primarily driven by higher headcount and costs incurred to obtain the Third Gilead Agreement Amendment. Non-cash stock-based compensation expense was $10 million for the second quarter 2024, compared to $9 million for the same period in 2023.
•Net Loss was $93 million for the second quarter 2024, compared to $75 million for the same period in 2023.
