Arcus Biosciences Reports Fourth Quarter and Full Year 2020 Financial Results and Provides Operational Highlights

HAYWARD, Calif.–(BUSINESS WIRE)–Feb 24, 2021–
Arcus Biosciences, Inc. (NYSE:RCUS), an oncology-focused biopharmaceutical company working to create best-in-class cancer therapies, today reported financial results for the fourth quarter and year ended December 31, 2020 and provided operational highlights.
“With $735 million in cash at the end of the year, plus $220 million from Gilead’s recent equity investment, we are extremely well-positioned to accelerate the advancement of our pipeline, initiate our first registrational trials for domvanalimab, and deliver multiple readouts from the randomized portions of our ongoing clinical studies,” said Terry Rosen, Ph.D., CEO. “These readouts include the interim analysis for ARC-7, our Phase 2 randomized study evaluating domvanalimab and zimberelimab in first-line, PD-L1 high, non-small cell lung cancer, in the second quarter of 2021, as well as initial data from our randomized studies evaluating our A 2a /A 2b adenosine receptor antagonist, etrumadenant. In 2021, we also expect to continue to advance AB680, our CD73 inhibitor, in pancreatic cancer and to expand the clinical program for this first-in-class small molecule to other tumor types. We are also pleased to announce that we received IND clearance for AB308 in January, allowing us to achieve a new milestone with five molecules now in clinical development, and we expect to advance at least one new small molecule program into clinical development in the second half of 2021.”
Corporate and Partnership Updates

  • Announced that Gilead increased its ownership in Arcus from approximately 13.0% to 19.5%. The $220 million received from this investment will enable Arcus to accelerate the development plans for Arcus’s five clinical-stage molecules.
  • Continued to advance our clinical collaboration with AstraZeneca for the conduct of PACIFIC-8, a registrational trial designed to evaluate domvanalimab and durvalumab in Stage 3 non-small cell lung cancer (NSCLC). We expect this trial to start in the second half of 2021.
  • Expanded our relationship with Wuxi Biologics and Arcus’s portfolio of molecules targeting the ATP-adenosine axis through a licensing and collaboration agreement with WuXi for anti-CD39 antibodies. We expect to file an IND for an antibody from this program in 2022 and to develop it in combination with our first-in-class small molecules targeting other points of intervention in this pathway.
  • As part of our option agreement with Taiho for their development and commercialization of Arcus’s molecules in Japan and other territories in Asia (excluding China), Taiho is planning to initiate clinical development of zimberelimab, our anti-PD-1 antibody, to advance assets in their portfolio. To date, Taiho has exercised its option rights to zimberelimab and etrumadenant.

Domvanalimab (FcR-silent TIGIT antibody)
Recent Highlights:

  • Initiated ARC-10, Arcus’s first registrational trial, evaluating domvanalimab + zimberelimab vs. zimberelimab vs. chemotherapy in first-line PD-L1≥50%, locally advanced or metastatic NSCLC. This “two-in-one” study involves a single trial to support the potential approvals of both zimberelimab monotherapy and domvanalimab + zimberelimab, and the timing of the study initiation aligns well with the planned interim analysis for ARC-7 in the second quarter. We expect to initiate other registrational trials for domvanalimab later in the year.

Upcoming Milestones:

  • Interim analysis from ARC-7, our randomized, three-arm Phase 2 trial ongoing in the U.S. and Asia, evaluating zimberelimab + domvanalimab vs. zimberelimab vs. zimberelimab + domvanalimab + etrumadenant in first-line PD-L1≥50% locally advanced or metastatic NSCLC, is expected in the second quarter of 2021, and we plan to provide a directional update on the data at that time. We expect to present data from this analysis at a medical conference in the second half of 2021.

AB680 (CD73 inhibitor)
Recent Highlights:

  • Presented promising preliminary data from the dose-escalation portion of ARC-8, our Phase 1/1b study evaluating AB680 in combination with zimberelimab and gemcitabine/nab-paclitaxel (G/NP) in first-line metastatic pancreatic cancer at the ASCO GI Conference in January.
    • As of the efficacy data cut-off date (DCO) of 12/9/20, 17 patients across the four dose-escalation cohorts (25mg, 50mg, 75mg and 100mg) were evaluable for response. In these patients, the objective response rate (ORR) was 41% (three confirmed partial responses (PRs), four PRs pending a second confirmatory scan). One of the confirmed PRs converted to a complete response after the DCO.
    • The confirmed ORR for Abraxane® (nab-paclitaxel), as stated in its FDA approved label for use in combination with gemcitabine, is 23%. To date, PD-1 antibodies have not shown any benefit when added to G/NP in this setting. 1,2,3,4
  • Initiated enrollment of the dose-expansion portion of ARC-8 using a dosing regimen of 100mg of AB680 administered intravenously every two weeks. Due to ARC-8’s rapid enrollment, we expect to open a control arm of AB680 plus G/NP by the end of this quarter, which will inform the design of a potential registrational trial. We and our investigators continue to be encouraged by the number of responses seen in ARC-8, and if data continue to look promising, we anticipate discussing these data with health authorities later in the year.
  • Nearing completion of a study with the oral formulation of AB680 in healthy volunteers. Having both oral and intravenous formulations of AB680 will give us flexibility to customize AB680’s dosing regimens based upon the combination partner.
  • Initiated enrollment of our first cohort evaluating the combination of AB680 and etrumadenant. This cohort is part of our ongoing ARC-6 metastatic castrate-resistant prostate cancer (mCRPC) platform study. We also intend to evaluate AB680 + etrumadenant combinations in our ARC-9 metastatic colorectal cancer (mCRC) platform study and to evaluate other AB680 combinations in other settings and tumor types.

Upcoming Milestones:

  • More mature data from ARC-8, including data from the dose-escalation and dose-expansion cohorts, are expected to be presented at a medical conference in the second half of 2021.

Etrumadenant (A 2a /A 2b adenosine receptor antagonist)
Recent Highlights:

  • Initiated the Stage 2 randomized portion of the etrumadenant + zimberelimab + docetaxel cohort in ARC-6, our ongoing Phase 1b/2 platform study evaluating etrumadenant-based combinations in mCRPC. Stage 2 was initiated after passing the Stage 1 futility assessment and is evaluating etrumadenant + zimberelimab + docetaxel vs. a docetaxel control arm.
  • Initiated ARC-9, a randomized Phase 1b/2 platform study to evaluate etrumadenant in combination with other agents in 2L+ mCRC based on intriguing durability and response data, particularly those in late-line mCRC patients, from the ARC-3 study.

Upcoming Milestones:

  • Updated data from ARC-3, including overall survival and progression-free survival data for the 3L+ mCRC cohort, will be presented at the American Association for Cancer Research (AACR) Virtual Meeting being held April 10-15, 2021 (week 1) and May 17-21, 2021 (week 2).
  • Initial data from Stage 1 of ARC-6 are expected to be presented in the second quarter of 2021. These data will be from the etrumadenant + zimberelimab + docetaxel cohort in 2L mCRPC in patients that failed androgen deprivation therapy. Initial data from the Stage 2 randomized portion, which compares this etrumadenant combination to docetaxel, are expected to be presented in the second half of 2021.
  • Initial randomized data from ARC-4, our ongoing study evaluating etrumadenant + zimberelimab + chemotherapy vs. zimberelimab + chemotherapy in EGFR mut tyrosine kinase inhibitor (TKI)-relapsed and refractory NSCLC, are expected to be presented at a medical conference in the second half of 2021.

Other Programs

  • Received IND clearance for AB308, Arcus’s FcR-enabled anti-TIGIT antibody, in January. We plan to evaluate AB308 in settings where the depletion of TIGIT-bearing cancer cells could be beneficial, such as certain hematological malignancies.
    • Our Phase 1/1b dose-escalation study for AB308, which will leverage Arcus’s anti-TIGIT antibody development experience, is designed to quickly establish the safety, pharmacokinetics and pharmacodynamics of AB308 in combination with zimberelimab and could enable the advancement of AB308 into a registrational trial by year-end 2021.
  • Initiation of clinical development for our HIF-2a inhibitor is anticipated in the second half of 2021.

Financial Results for the Fourth Quarter and Full Year Ended December 31, 2020

  • Cash, cash equivalents and investments were $735.1 million as of December 31, 2020, compared to $188.3 million at December 31, 2019. After December 31, 2020, Arcus received an additional $220.4 million in proceeds from the sale of equity to Gilead. The increase from December 31, 2019 to December 31, 2020 was primarily due to net proceeds of $326.2 million from the May 2020 public equity offering and $375 million received upon closing of the Gilead agreements, partially offset by cash utilized for our operations. We expect cash, cash equivalents and investments on-hand to be sufficient to fund operations at least through 2023.
  • Revenues: Collaboration and license revenues were $9.5 million for the three months ended December 31, 2020, compared to $9.8 million for the same period in 2019. The revenues in 2020 were comprised of $7.7 million from our Gilead collaboration and $1.8 million from our Taiho agreement for both partners’ ongoing rights to access our research and development pipeline. The revenues in 2019 were solely from our Taiho agreement and related to $8.0 million for Taiho’s exercise of its option for rights to zimberelimab as well as $1.8 million for Taiho’s ongoing rights to access our research and development pipeline. Collaboration and license revenues were $77.5 million for the full year ended December 31, 2020, compared to $15.0 million for the same period in 2019.
  • R&D Expenses: Research and development expenses were $48.7 million for the three months ended December 31, 2020, compared to $20.7 million for the same period in 2019. The increase was primarily due to increases in manufacturing and clinical costs required to supply and conduct our ongoing clinical studies, as well as increases in employee compensation costs driven by an increase in our headcount, approximately $2.6 million of which consists of non-cash stock-based compensation. Research and development expenses were $159.3 million for the full year ended December 31, 2020, compared to $78.5 million for the same period in 2019.
  • G&A Expenses: General and administrative expenses were $12.8 million for the three months ended December 31, 2020, compared to $6.6 million for the same period in 2019. The increase in expense was due to increases in employee compensation driven by an increase in headcount, approximately $2.9 million of which consists of non-cash stock-based compensation costs. Additional increases in legal and accounting expenses resulted from ongoing public company compliance obligations. General and administrative expenses were $42.4 million for the full year ended December 31, 2020, compared to $25.2 million for the same period in 2019.
  • Net Loss: Net loss was $51.9 million for the three months ended December 31, 2020, compared to a net loss of $16.6 million for the same period in the prior year. The increase in net loss was primarily attributable to an increase in operating expenses as noted above. Net loss for the full year ended December 31, 2020 was $122.9 million, compared to $84.7 million for the same period in 2019.
