Arcus Biosciences reported that the Phase 3 STAR-121 study in first-line metastatic non-small cell lung cancer, conducted with Gilead Sciences, has been discontinued for futility based on an Independent Data Monitoring Committee recommendation after a pre-planned futility analysis. Safety was not reassessed in that analysis, and no new safety issues have emerged in ongoing IDMC safety reviews. The related Phase 2 EDGE-Lung study will also be discontinued. The study’s exploratory arm showed zimberelimab plus chemotherapy delivering overall survival consistent with pembrolizumab plus chemotherapy.
Arcus also disclosed that Gilead will allow its broader option period to lapse on July 14, 2026 by not making an option continuation payment.

Arcus continues to hold full rights to casdatifan globally except for rights previously licensed to Taiho in Japan and certain other Asian territories, excluding China.

Arcus Biosciences is a late clinical-stage biopharmaceutical company developing small‑molecule and antibody therapies for cancer and inflammatory and autoimmune diseases. It remains loss‑making and expects significant future losses as it funds extensive research and clinical trials.
The lead oncology asset, casdatifan (HIF‑2α inhibitor), has shown improved efficacy versus belzutifan in late‑line renal cell carcinoma and is in a Phase 3 trial (PEAK‑1) with more Phase 3 work planned. Quemliclustat is in a fully enrolled Phase 3 pancreatic cancer study with results expected in the first half of 2027. TIGIT antibody domvanalimab saw one major gastrointestinal Phase 3 study stopped for futility, but lung cancer trials continue. Arcus is also advancing an oral inflammation pipeline, including MRGPRX2 and TNF programs, with first clinical studies targeted around 2026.
The company relies heavily on strategic partnerships, notably a broad multi‑program collaboration with Gilead that includes options, co‑development, co‑promotion and royalties, and regional licensing with Taiho. It highlights substantial risks around funding needs, clinical and regulatory outcomes, dependence on collaborators and manufacturers, intellectual property protection, competition, cybersecurity and evolving healthcare regulation.
Arcus Biosciences reported fourth-quarter and full-year 2025 results alongside a broad pipeline update. Q4 2025 revenue was $33 million, down from $36 million a year earlier, and the company recorded a net loss of $106 million versus $94 million.
For full-year 2025, total revenue was $247 million and net loss was $353 million. Q4 research and development expenses rose to $121 million, reflecting higher late-stage trial activity, while general and administrative costs were $26 million. Cash, cash equivalents and marketable securities totaled $1.0 billion at December 31, 2025, and Arcus expects funding to last until at least the second half of 2028.
Arcus highlighted strong new data for casdatifan in late-line kidney cancer, with a median progression-free survival of 15.1 months and a confirmed overall response rate of about 45% in the 100mg once-daily cohort. The company is running the Phase 3 PEAK-1 study, planning another Phase 3 trial in first-line metastatic kidney cancer by the end of 2026, and expects at least two casdatifan data readouts in 2026.
