HAYWARD, Calif.–(BUSINESS WIRE)–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, 2022 and provided a pipeline update on its six clinical-stage molecules – targeting TIGIT, the adenosine axis (CD73 and A2a/A2b), HIF-2a and PD-1 – across multiple common cancers. Arcus and Gilead continue to rapidly advance Arcus’s broad and diverse pipeline, and the companies remain on track to have four ongoing registrational Phase 3 trials of domvanalimab-based combinations in non-small cell lung cancer (NSCLC) and gastrointestinal (GI) cancers by year-end. Topline disclosure from the Phase 2 ARC-7 study is expected in the second half of 2022 with a planned presentation of the data at a medical conference in 2023. Arcus continues to advance its next wave of novel molecules, with at least two INDs expected in 2023.
“This is a transformational year in the evolution of Arcus, as we expand the scope of our global clinical programs to include four registrational Phase 3 trials with domvanalimab-based combinations,” said Terry Rosen, Ph.D., chief executive officer of Arcus. “The data we have generated in our Phase 2 ARC-7 study support our conviction in the initiation of two new registrational Phase 3 trials with our domvanalimab plus zimberelimab anti-TIGIT / anti-PD-1 doublet regimen, and we intend to be the leader in bringing anti-TIGIT-based therapies to patients. Our strong cash position and strategic collaborations enable us to maintain competitive positioning and execute efficiently in disease areas with significant patient populations and high unmet need, including lung and upper GI cancers.”
Anti-TIGIT program (domvanalimab and AB308)
Update on Domvanalimab:
- Arcus is on track to complete enrollment in Q3 2022 of 150 patients for ARC-7, a randomized Phase 2 study evaluating the safety and efficacy of zimberelimab alone vs. domvanalimab plus zimberelimab vs. domvanalimab plus zimberelimab and etrumadenant in first-line PD-L1≥50% metastatic NSCLC.
-
Arcus and Gilead are pursuing a broad development program for domvanalimab-based combinations in NSCLC, with three ongoing or soon-to-be initiated registrational Phase 3 trials:
- STAR-121, evaluating the combination of domvanalimab plus zimberelimab and chemotherapy versus pembrolizumab with chemotherapy in first-line NSCLC PD-L1 all-comers, is expected to achieve first site initiation in the third quarter and is being operationalized by Gilead.
- ARC-10 is evaluating domvanalimab plus zimberelimab vs. zimberelimab alone vs. chemotherapy in first-line PD-L1≥50% locally advanced or metastatic NSCLC.
- PACIFIC-8, operationalized by AstraZeneca, is evaluating domvanalimab plus durvalumab, an anti-PD-L1 antibody, in unresectable Stage III NSCLC.
-
The companies are also advancing the study of domvanalimab plus zimberelimab-based combinations with two new studies in GI cancers, which are on track to start by year-end:
- ARC-21, a Phase 2 trial evaluating domvanalimab plus zimberelimab-based combinations in upper GI cancers, is open for enrollment and is intended to support the registrational Phase 3 trial STAR-221.
- STAR-221, a randomized Phase 3 study, will evaluate a domvanalimab plus zimberelimab-based combination in upper GI cancers.
Upcoming Anti-TIGIT Milestones:
- Topline disclosure from the Phase 2 ARC-7 study is expected in the second half of 2022 with a planned presentation of the data at a medical conference in 2023.
- Arcus and Gilead expect to initiate two Phase 2 platform lung studies evaluating novel domvanalimab-based combinations, including domvanalimab plus zimberelimab-based triplet combinations with etrumadenant, Trodelvy® (sacituzumab govitecan-hziy), and/or quemliclustat, by year-end.
Etrumadenant (A2a/A2b adenosine receptor antagonist)
Upcoming Etrumadenant Milestones:
- Topline disclosure from the Phase 2 ARC-7 study is expected in the second half of 2022 with a planned presentation of the data at a medical conference in 2023.
- Data from the randomized cohort of ARC-6 evaluating etrumadenant plus zimberelimab and docetaxel versus docetaxel in second-line metastatic castrate-resistant prostate cancer (CRPC) are anticipated in-house in the second half of 2022 with a presentation of results expected in 2023.
- Data from ARC-9, a Phase 1b/2 study evaluating etrumadenant-based combinations in second-line and third-line metastatic colorectal cancer (mCRC), are expected in the first half of 2023.
Quemliclustat (small-molecule CD73 inhibitor)
Update on ARC-8:
- The ARC-8 study includes two stages: the first stage is a dose-escalation and dose-expansion stage evaluating quemliclustat plus a chemotherapy doublet and zimberelimab (the quad) followed by the second stage, a randomized cohort comparing the quad versus quemliclustat plus a chemotherapy doublet in first-line PDAC.
-
Arcus conducted an interim analysis for ARC-8, which included patients from the first stage of the trial and the initial two-thirds of patients from the second stage.
- At this interim analysis, we continued to observe encouraging data from patients treated in the first stage of ARC-8. However, data from patients treated in the randomized portion were similar to historical benchmarks for chemotherapy alone.
- At the time of data cut off, no unexpected safety signals were observed.
- The companies plan to wait for more mature PFS and overall survival data from all 90 patients in the randomized cohort to inform next steps for the PDAC program. These data are expected in the first half of 2023.
Upcoming Quemliclustat Milestones:
- As mentioned above, Arcus and Gilead expect to initiate a Phase 2 platform study to evaluate domvanalimab and quemliclustat combinations in NSCLC by year-end. We also expect to explore quemliclustat-based combinations in GI cancers in the ARC-21 study.
AB521 (HIF-2a inhibitor)
AB521 Update:
- Arcus is on track to initiate ARC-20, a Phase 1/1b study to explore the safety and clinical activity of AB521 in cancer patients in Q3 2022. Data from the ongoing healthy volunteer study enable Arcus to start dose escalation in patients at a pharmacologically relevant dose level. Pharmacokinetic (PK)/pharmacodynamic (PD) data for AB521 in healthy volunteers demonstrate its potential to have an improved clinical profile compared to the approved HIF-2a inhibitor.
Discovery Programs:
- AB598 (anti-CD39 antibody) continues to progress through preclinical development, and we expect to file an Investigational New Drug (IND) application and initiate a Phase 1 trial in cancer patients in the first half of 2023.
- Arcus nominated a new small molecule development candidate, AB801, a potent and selective AXL inhibitor, which has the potential to address various treatment-resistant tumor types, such as STK11-mutant NSCLC.
- Arcus expects to nominate a potential first-in-class small molecule candidate designed to treat a wide range of inflammatory conditions in the second half of 2022.
- As part of Arcus’s and Gilead’s research collaboration, the companies have now selected targets for the two drug discovery programs in oncology. Upon completion of certain IND-enabling activities, Gilead has the right to exercise its option for a payment of $60 million for each program.
Financial Results for the Second Quarter 2022
- Cash, cash equivalents and investments: were $1,271.1 million as of June 30, 2022, compared to $681.3 million as of December 31, 2021. The increase was primarily due to the receipt of $725 million from Gilead in January 2022. Arcus expects cash, cash equivalents and marketable securities on-hand to be sufficient to fund operations into 2026.
- Revenues: Collaboration and license revenues were $26.8 million for the three months ended June 30, 2022, compared to $9.5 million for the same period in 2021. In the three months ended June 30, 2022, Arcus recognized $16.7 million in license and development service revenues for all programs optioned by Gilead, based on estimates of progress made toward satisfying the related performance obligations, $8.3 million in collaboration revenue related to Gilead’s ongoing rights to access Arcus’s research and development pipeline in accordance with the Gilead collaboration agreement, as well as $1.8 million related to the collaboration agreement with Taiho. In the three months ended June 30, 2021, Arcus recognized $7.7 million in other collaboration revenue related to Gilead’s access to Arcus’s research and development pipeline, as well as $1.8 million related to the Taiho collaboration agreement. Collaboration and license revenues were $44.8 million for the six months ended June 30, 2022, compared to $18.9 million for the same period in 2021.
- R&D Expenses: Research and development expenses were $69.9 million for the three months ended June 30, 2022, compared to $68.8 million for the same period in 2021. Arcus’s expanding clinical and development activities for domvanalimab and zimberelimab drove increases in manufacturing and clinical costs. Arcus’s growing employee base and 2022 stock awards drove an increase in employee compensation costs, including a $0.7 million increase in non-cash stock-based compensation to approximately $7.7 million. The above increases in research and development costs were mostly offset by increased cost-sharing reimbursements compared to the same quarter in the prior year. The increase in cost-sharing reimbursements was driven by the four programs optioned by Gilead in the current quarter, compared to a single program in the same quarter of the prior year. Research and development expenses were $131.1 million for the six months ended June 30, 2022, compared to $135.2 million for the same period in 2021.
- G&A Expenses: General and administrative expenses were $25.8 million for the three months ended June 30, 2022, compared to $16.8 million for the same period in 2021. The increase was driven by the increased administrative costs to support the growing size and complexity of Arcus’s clinical development organization associated with Arcus’s expanding clinical pipeline and collaboration obligations. Arcus’s growing employee base and 2022 stock awards drove increases in employee compensation costs and facilities expense, including a $1.6 million increase in non-cash stock-based compensation to approximately $8.0 million for the three months ended June 30, 2022 compared to the prior year period. General and administrative expenses were $49.8 million for the six months ended June 30, 2022, compared to $32.6 million for the same period in 2021.
- Net Loss: Net loss was $66.6 million for the three months ended June 30, 2022, compared to a net loss of $76.0 million for the same period in the prior year. Net loss was $134.6 million for the six months ended June 30, 2022, compared to a net loss of $148.6 million for the same period in the prior year.

About the Gilead Collaboration
In May 2020, Gilead and Arcus entered into a 10-year collaboration that provided Gilead immediate rights to zimberelimab and the right to opt into all other Arcus programs arising during the collaboration term. In November 2021, Gilead and Arcus amended the collaboration in connection with Gilead’s option exercise for three of Arcus’s then-clinical stage programs. For all other programs that are in clinical development or new programs that enter clinical development thereafter, the opt-in payments are $150 million per program. Gilead’s option, on a program-by-program basis, expires after a specified period of time following the achievement of a development milestone for such program and Arcus’s delivery to Gilead of the requisite qualifying data package. Concurrent with the May 2020 collaboration agreement, Gilead and Arcus entered into a stock purchase agreement under which Gilead made a $200 million equity investment in Arcus. That stock purchase agreement was amended and restated in February 2021 in connection with Gilead’s increased equity stake in Arcus from 13% to 19.5%, with an additional $220 million investment.
Gilead and Arcus are co-developing and equally share global development costs for five clinical candidates, including domvanalimab, an Fc-silent anti-TIGIT antibody, etrumadenant, a dual adenosine A2a/A2b receptor antagonist, quemliclustat, a small molecule inhibitor of CD73, and zimberelimab, an anti-PD1 antibody.
