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 fourth quarter and full year ended December 31, 2023, 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.
“By the beginning of next year, we expect to have six ongoing Phase 3 trials for three distinct programs: domvanalimab plus zimberelimab, our Fc-silent anti-TIGIT antibody and anti-PD-1 antibody combination; casdatifan (AB521), our HIF-2a inhibitor; and quemliclustat, our CD73 inhibitor. Two of our Phase 3 trials (STAR-121 and STAR-221) for domvanalimab plus zimberelimab are expected to complete enrollment this year, and we are beginning preparations for regulatory filings,” said Terry Rosen, Ph.D., chief executive officer of Arcus. “We now have cash runway into 2027, enabling us to accelerate our multiple late-clinical stage studies and support our highly productive discovery engine.”
Corporate Update:
- In January 2024, Gilead and Arcus announced an amendment to their collaboration agreement and a separate equity investment, raising Gilead’s ownership stake to 33%. In connection with the announcement, Gilead’s Chief Commercial Officer, Johanna Mercier, joined Arcus’s board.
- In December 2023, Arcus and Exelixis announced a clinical trial collaboration for STELLAR-009, a Phase 1b/2 trial evaluating casdatifan in combination with zanzalintinib in patients with advanced solid tumors, including clear cell renal cell carcinoma (ccRCC). The trial is currently enrolling.
Pipeline Highlights:
Domvanalimab (Fc-silent anti-TIGIT monoclonal antibody) plus Zimberelimab (anti-PD-1 antibody)
Domvanalimab-zimberelimab Updates:
-
Arcus and Gilead announced strategic changes and enrollment updates to their domvanalimab + zimberelimab clinical program to focus on settings with the highest unmet medical need and where the Fc-silent design of domvanalimab has the potential for differentiation in both efficacy and safety.
- Enrollment was discontinued for the Phase 3 study ARC-10 evaluating domvanalimab plus zimberelimab compared to pembrolizumab in first-line PD-L1-high NSCLC. This enables a potential acceleration of the Phase 3 study STAR-121 in the all-comer first-line NSCLC setting.
- Arcus and Gilead plan to initiate STAR-131, a registrational Phase 3 study in perioperative NSCLC.
- The companies also plan to initiate a Phase 2 trial to evaluate domvanalimab plus zimberelimab in a new disease setting.
Upcoming Domvanalimab-Zimberelimab Milestones:
- Updated PFS and ORR data from the Phase 2 EDGE-Gastric trial evaluating domvanalimab + zimberelimab + chemotherapy in first-line upper GI cancers are expected to be presented at the ASCO Annual Meeting in June 2024. This study is evaluating a similar regimen and patient population as our STAR-221 phase 3 study.
- Data and insights from previously enrolled patients in the ARC-10 study (Part 1) are expected to be shared at future scientific conferences.
- The Phase 3 studies STAR-221 and STAR-121 are expected to complete enrollment by year-end.
Casdatifan, also known as AB521 (HIF-2a inhibitor)
Casdatifan (AB521) Updates:
-
Arcus shared PK, PD, safety, and early efficacy data from the dose-escalation phase of ARC-20, a Phase 1/1b study of casdatifan in cancer patients.
-
PK, PD, and Safety Data:
- PD data demonstrated that a 20 mg daily dose of casdatifan (one-fifth the selected Phase 3 dose of 100 mg) achieved a similar level of HIF-2a-mediated EPO suppression as the 120 mg approved dose of the marketed competitor, belzutifan.
- Dose-proportional PK were observed through the selected Phase 3 dose of 100 mg of casdatifan. By contrast, plasma levels of belzutifan do not meaningfully increase above the approved dose of 120 mg.
- Together, the PK and PD profile observed suggests that the selected dose of 100mg of casdatifan has the potential to achieve substantially greater HIF-2a inhibition than the approved dose of belzutifan.
- No dose-limiting toxicities have been observed to date in ARC-20.
- To date, rates of adverse events, including anemia and hypoxia, appear consistent with observations from historical trials of belzutifan.
- Early efficacy data from the dose-escalation and 100 mg dose-expansion cohorts will be discussed on today’s conference call.
-
PK, PD, and Safety Data:
- Arcus intends to initiate a Phase 3 combination study in ccRCC in early 2025.
Upcoming Casdatifan (AB521) Milestones:
-
Efficacy data from the dose-expansion stage of the ARC-20 study are expected to be presented at a medical conference in the second half of 2024.
- The data will focus on the cohort of 30 patients treated with a 100 mg daily dose of casdatifan.
- In addition, a 50 mg daily expansion cohort is currently enrolling and a to-be-determined higher dose expansion cohort is planned; data from these cohorts will be shared at a later date.
Quemliclustat (small-molecule CD73 inhibitor)
-
Arcus presented overall survival data at the 2024 ASCO GI conference from the ongoing Phase 1/1b ARC-8 trial evaluating quemliclustat plus chemotherapy with or without zimberelimab in patients with previously untreated metastatic pancreatic ductal adenocarcinoma (mPDAC).
- Median Overall Survival (mOS) was 15.7 months for all patients treated with 100 mg quemliclustat-based regimens (pooled analysis) in the ARC-8 study, which exceeds the historical benchmark data for chemotherapy alone.
- A 37% reduction in risk of death and a 5.9-month improvement in mOS was observed for patients treated with quemliclustat-based regimens when compared to a Synthetic Control Arm of 1:1 matched patients who were treated with gemcitabine/nab-paclitaxel in Phase 2 and 3 clinical studies in a post hoc analysis.
- Initiation of a Phase 3 trial in pancreatic cancer is expected to begin by early 2025.
Etrumadenant (A2a/A2b adenosine receptor antagonist)
- Data from ARC-9, a randomized Phase 1b/2 study evaluating etrumadenant plus zimberelimab plus chemotherapy versus regorafenib in third-line metastatic colorectal cancer (mCRC) are expected to be presented in the first half of 2024.
- Data from MORPHEUS-PDAC, a randomized Phase 2 platform study operationalized by Roche evaluating etrumadenant plus atezolizumab plus chemotherapy versus chemotherapy in first-line metastatic pancreatic ductal adenocarcinoma, are expected to be presented in the first half of 2024.
Early Clinical and Preclinical Programs
- Arcus initiated ARC-27, a Phase 1 study of AB801, Arcus’s potent and highly selective AXL inhibitor, in advanced cancer patients and expects to initiate the first expansion cohort in NSCLC in 2025.
- Arcus is conducting preclinical toxicity studies on multiple development candidates against KIT, a target involved in multiple allergic and immune-mediated diseases.
Financial Results for Fourth Quarter and Full Year 2023:
- Cash, Cash Equivalents and Marketable Securities were $866 million as of December 31, 2023, compared to $1.1 billion as of December 31, 2022. The decrease during the year is primarily due to the use of cash in research and development activities, partially offset by receipts totaling $49 million in upfront and milestone payments from Gilead and Taiho, and $33 million in proceeds from the issuance of 2.6 million shares of our common stock including shares pursuant to an equity award plan. Together with the $320 million we received from Gilead for their equity investment in January 2024, our cash, cash equivalents and marketable securities were $1.2 billion, which we believe will be sufficient to fund our planned operations into 2027. Cash, cash equivalents and marketable securities are expected to be between $870 and $920 million at the end of 2024.
- Revenues were $31 million for the fourth quarter 2023, compared to $34 million for the same period in 2022. In the fourth quarter 2023, Arcus recognized $22 million in License and development service revenues related to the advancement of programs, primarily the Gilead collaboration, as well as $9 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 $117 million for the full year 2023, compared to $112 million for the same period in 2022.
- Research and Development (R&D) Expenses were $93 million for the fourth quarter 2023, compared to $80 million for the same period in 2022. The net increase of $13 million was primarily driven by higher costs to support our late-stage development program activities. Non-cash stock-based compensation expense was $9 million for each of the fourth quarter 2023 and 2022. R&D expenses were $340 million for the full year 2023, compared to $288 million for the same period in 2022. For fourth quarter 2023 and 2022, Arcus recognized gross reimbursements of $42 million and $49 million, respectively, for shared expenses from its collaborations, primarily the Gilead collaboration. Gross reimbursements were $162 million for the full year 2023, compared to $161 million for 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.
- General and Administrative (G&A) Expenses were $29 million for the fourth quarter 2023, compared to $28 million for the same period in 2022. Non-cash stock-based compensation expense was $9 million for the fourth quarter 2023, compared to $8 million for the same period in 2022. G&A expenses were $117 million for the full year 2023, compared to $104 million for 2022.
- Net Loss was $81 million for the fourth quarter 2023, compared to $67 million for the same period in 2022. The increase in net loss included an increase of $1 million in income tax expense primarily due to an increase in taxable income compared to the prior year. Net loss was $307 million for the full year 2023, compared to $267 million for 2022.
