Arcus Biosciences Reports Third Quarter 2023 Financial Results and Provides a Pipeline Update
- Domvanalimab shows encouraging objective response rates (ORR) and high progression-free survival (PFS) in the Phase 2 EDGE-Gastric study, positioning it as a potential first-to-market anti-TIGIT antibody for upper GI adenocarcinomas. AB521's consistent results in cancer patients and potential for greater HIF-2a inhibition than competitors bode well for Arcus's future. The company's strong financial position with $950 million in cash and funding expected into 2026 provides stability and resources for pipeline advancement.
- None.
- Data were presented from the ongoing EDGE-Gastric Phase 2 study in first-line upper GI cancers at the Annual Meeting of the American Society of Clinical Oncology (ASCO) Plenary Series; domvanalimab is the only Fc-silent anti-TIGIT antibody in Phase 3 for upper GI adenocarcinomas and has the potential to be first-to-market for these cancers.
- Pharmacokinetic and pharmacodynamic data from the dose-escalation phase of ARC-20, a Phase 1b study in cancer patients of AB521, a potential best-in-class HIF-2a inhibitor, are consistent with results seen in healthy volunteers; more details, including preliminary signs of efficacy, are expected in early 2024.
- An analysis of efficacy and safety data from the Phase 1/1b ARC-8 study of quemliclustat in advanced pancreatic cancer will be presented in early 2024.
-
With
in cash, cash equivalents and marketable securities and funding expected into 2026, Arcus is well positioned to advance its pipeline.$950 million
“As we continue to execute on our Phase 3 trials for domvanalimab in lung and GI cancers, we have one of three important near-term data readouts now behind us. Today’s presentation of data from our Phase 2 EDGE-Gastric study provided important evidence to support domvanalimab’s potential as a differentiated and first-to-market anti-TIGIT antibody for the treatment of first-line upper GI adenocarcinomas. We are also looking forward to sharing more on our HIF-2a inhibitor, AB521, which continues to show a potentially improved clinical profile, with PK/PD results in patients consistent with those seen in healthy volunteers,” said Terry Rosen, Ph.D., chief executive officer of Arcus. “Lastly, we will be presenting mature OS data from our Phase 1/1b study of quemliclustat in pancreatic cancer early next year; we are excited to share next steps in the coming months.”
Pipeline Highlights:
Domvanalimab (Fc-silent anti-TIGIT monoclonal antibody)
-
Preliminary data from Arm A1 of the Phase 2 EDGE-Gastric study, evaluating domvanalimab plus zimberelimab and chemotherapy in patients with previously untreated, locally advanced unresectable or metastatic upper gastrointestinal (GI) cancers, were presented during the Annual Meeting of the American Society of Clinical Oncology (ASCO) Plenary Series on November 7, 2023. These data were from the cohort that includes a patient population and dosing regimen similar to the ongoing Phase 3 study, STAR-221.
-
Domvanalimab plus zimberelimab and chemotherapy showed encouraging objective response rates (ORR) of
80% (confirmed ORR (cORR) of73% ) in patients with PD-L1-high tumors (TAP ≥5% ),46% (all confirmed) in patients with PD-L1-low tumors (TAP <5% ) and59% (cORR of56% ) for patients overall. -
Six-month landmark progression-free survival (PFS) was
93% for patients with PD-L1-high tumors (TAP ≥5% ),68% for patients with PD-L1-low tumors (TAP <5% ) and77% for patients overall. - Mature PFS has not been reached and data are expected in the second half of 2024.
- Domvanalimab plus zimberelimab and chemotherapy was well tolerated, with a similar safety profile to what has been reported for anti-PD-1 plus chemotherapy in this setting.
- Domvanalimab is the only Fc-silent anti-TIGIT antibody in Phase 3 for gastric, gastroesophageal junction and esophageal adenocarcinoma and has the potential to be first to market for these cancers. These tumor types represent a potential drug-treatable population of over 25,000 in the US and over 100,000 in G-7 countries.
-
Domvanalimab plus zimberelimab and chemotherapy showed encouraging objective response rates (ORR) of
AB521 (HIF-2a inhibitor)
-
Pharmacokinetic (PK) and pharmacodynamic (PD) data from the dose-escalation phase of ARC-20, a Phase 1/1b study of AB521 in cancer patients, are consistent with the results seen in healthy volunteers to date.
- No dose-limiting toxicities have been observed to date in ARC-20.
- Detailed PK, PD and safety data along with preliminary anti-tumor activity from this stage of ARC-20 will be shared in early 2024.
- Enrollment for the dose-expansion stage of ARC-20 in clear cell renal cell carcinoma (ccRCC) patients is near completion. Efficacy data from this stage of the ARC-20 study are expected later in 2024. The dose-expansion stage will include 30 patients on a 100-mg daily dose, which Arcus believes has the potential to achieve substantially greater HIF-2a inhibition than the approved dose of the marketed competitor.
- A Phase 2 study evaluating AB521 in combination with a tyrosine kinase inhibitor (TKI) is anticipated to begin in the fourth quarter of 2023.
Quemliclustat (small-molecule CD73 inhibitor)
-
Arcus conducted an analysis of mature OS data (minimum follow-up of 18 months) from the ongoing Phase 1/1b ARC-8 trial evaluating quemliclustat plus chemotherapy with or without zimberelimab in first-line pancreatic cancer.
- At this analysis, 122 patients in the study had received the go-forward dose of 100 mg of quemliclustat; median follow-up time was 21 months.
- These data will be presented in early 2024.
Etrumadenant (A2a/A2b adenosine receptor antagonist)
- Data from ARC-9, a Phase 1b/2 study evaluating etrumadenant plus zimberelimab plus chemotherapy in second-line and third-line metastatic colorectal cancer (mCRC), which is fully enrolled, are expected in the first half of 2024.
Early Clinical and Preclinical Programs
- ARC-25, a Phase 1 trial in cancer patients for AB598, an anti-CD39 antibody, is currently enrolling.
- Arcus initiated a Phase 1 study in healthy volunteers of AB801, its potent and highly selective AXL inhibitor, and expects to initiate a Phase 1 study in advanced cancer patients in the first quarter of 2024.
- Arcus expects to select a new development candidate against KIT, a target involved in multiple allergic and immune-mediated diseases, by year end.
Financial Results for Third Quarter 2023:
-
Cash, Cash Equivalents and Marketable Securities were
as of September 30, 2023, compared to$950 million as of December 31, 2022. The decrease during the period is primarily due to the use of cash in research and development activities, partially offset by receipts of$1.1 billion in upfront payments from Gilead to initiate Arcus-led discovery and early development activities on two jointly selected inflammation targets and$35 million in proceeds from the issuance of 1.2 million shares of our common stock. Arcus now expects cash utilization between$25 million and$265 million for the year ended December 31, 2023. Arcus continues to expect cash, cash equivalents and marketable securities on-hand to be sufficient to fund operations into 2026.$290 million
-
Revenues were
for the third quarter 2023, compared to$32 million for the same period in 2022. In the third quarter 2023, Arcus recognized$33 million in license and development service revenues related to the advancement of programs, primarily the Gilead collaboration, as well as$22 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. Revenues were$10 million for the nine months ended September 30, 2023, compared to$86 million for the same period in 2022.$78 million
-
Research and Development (R&D) Expenses were
for the third quarter 2023, compared to$82 million for the same period in 2022. The net increase of$77 million was primarily driven by:$5 million of higher spend for Arcus programs not under a cost-sharing collaboration due to our expanding clinical and development activities; partially offset by a net decrease of$7 million in shared costs for programs optioned by our collaboration partners, primarily from the Gilead collaboration. The net decrease of$2 million was due to a decrease in shared collaboration costs of$2 million primarily from the timing of clinical manufacturing; with a corresponding decrease in reimbursements for shared expenses of$10 million . Non-cash stock-based compensation expense was$8 million for each of the third quarter 2023 and 2022. R&D expenses were$8 million for the nine months ended September 30, 2023, compared to$247 million for the same period in 2022. For third quarter 2023 and 2022, Arcus recognized reimbursements of$208 million and$33 million , respectively, for shared expenses from its collaborations, primarily the Gilead collaboration. Reimbursements were$41 million for the nine months ended September 30, 2023, compared to$119 million for the same period in 2022. 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.$111 million
-
General and Administrative (G&A) Expenses were
for the third quarter 2023, compared to$30 million for the same period in 2022. The increase was primarily driven by the increased complexity of supporting Arcus's expanding clinical pipeline and partnership obligations. Non-cash stock-based compensation expense was$26 million for the third quarter 2023, compared to$10 million for the same period in 2022. G&A expenses were$8 million for the nine months ended September 30, 2023, compared to$88 million for the same period in 2022.$76 million
-
Net Loss was
for the third quarter 2023, compared to$71 million for the same period in 2022. The increase in net loss included an increase of$65 million in income tax expense primarily due to an increase in taxable income compared to the prior year. Net loss was$2 million for the nine months ended September 30, 2023, compared to$226 million for the same period in 2022.$200 million

About the Gilead Collaboration
In May 2020, Arcus established a 10-year collaboration with Gilead to strategically advance our portfolio. Under this collaboration, Gilead obtained time-limited exclusive option rights to all of our clinical programs arising during the collaboration term. Arcus and Gilead are co-developing five investigational products, including zimberelimab (Arcus’s anti-PD-1 molecule), domvanalimab (Arcus’s anti-TIGIT antibody), etrumadenant (Arcus’s adenosine receptor antagonist) and quemliclustat (Arcus’s CD73 inhibitor). The collaboration was expanded in November 2021 to include research directed to two targets for oncology, which research collaboration was further expanded in May 2023 to add up to four targets for inflammatory diseases.
