Cabozantinib (s)-Malate

Data from the Phase 1/1b ARC-20 study cohort evaluating casdatifan plus cabozantinib in immunotherapy (IO)-experienced patients with clear cell renal cell carcinoma (ccRCC) will be presented in an oral session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting Additional data from the ARC-20 cohorts evaluating casdatifan monotherapy in patients who had progressed on both an anti-PD-1 and a tyrosine kinase inhibitor (TKI) therapy are expected in the fall Initiation of the Phase 3 study for PEAK-1 evaluating casdatifan plus cabozantinib versus cabozantinib in IO-experienced patients with ccRCC is expected in the second quarter of 2025 Arcus is well positioned to advance its full pipeline with $1.0 billion in cash, cash equivalents and marketable securities at quarter end HAYWARD, Calif.--(BUSINESS WIRE)-- Arcus Biosciences, Inc. (NYSE:RCUS), a clinical-stage, global biopharmaceutical company focused on developing differentiated molecules and combination therapies for patients with cancer, today reported financial results for the first quarter ended March 31, 2025, and provided a pipeline update on its clinical-stage investigational molecules across multiple common cancers. “Beginning with an oral presentation at ASCO for casdatifan in ccRCC, we expect to report a steady stream of data from ARC-20 throughout the remainder of 2025 and into 2026. We believe these data will support our robust development plan for casdatifan across multiple settings. This includes our Phase 3 trial, PEAK-1 in the IO-experienced setting, our clinical trial with AstraZeneca, which will combine casdatifan with their anti-PD-1/CTLA-4 bispecific antibody in the IO-naive setting, and three new cohorts in ARC-20 evaluating casdatifan in first- and second-line ccRCC,” said Terry Rosen, Ph.D., chief executive officer of Arcus. “We believe that casdatifan has the potential to change the treatment paradigm for ccRCC, including the displacement of TKIs in earlier line settings, and our development plan is designed to establish casdatifan as the HIF-2a inhibitor of choice. Our balance sheet remains strong, and our operational plan and priorities are focused on ensuring that casdatifan is funded through its first Phase 3 readout.” Pipeline Highlights: Casdatifan (HIF-2a inhibitor) Casdatifan Updates: New clinical data from three monotherapy expansion cohorts in ARC-20 were presented in an oral session at the 2025 ASCO Genitourinary (GU) Cancers Symposium in February. At the time of data cut-off (DCO, January 3, 2025), the efficacy-evaluable population included a total of 87 patients with ccRCC who had received at least two prior lines of therapy, including both anti-PD-1 and a vascular endothelial growth factor receptor 2 (VEGFR)-TKI therapy. These data support the potential for casdatifan to be a best-in-class HIF-2a inhibitor for the treatment of ccRCC: Despite limited follow-up, two of the cohorts exceeded 30% confirmed overall response rate (inclusive of one partial response that confirmed after the DCO) A 9.7-month median progression-free survival (PFS) was reached for the 50mg twice-daily casdatifan monotherapy cohort; median PFS was not yet reached for other cohorts No unexpected safety signals were observed at the time of DCO, and casdatifan had an acceptable and manageable safety profile across all doses Despite limited follow-up, two of the cohorts exceeded 30% confirmed overall response rate (inclusive of one partial response that confirmed after the DCO) A 9.7-month median progression-free survival (PFS) was reached for the 50mg twice-daily casdatifan monotherapy cohort; median PFS was not yet reached for other cohorts No unexpected safety signals were observed at the time of DCO, and casdatifan had an acceptable and manageable safety profile across all doses Planned Data Readouts: June 2025: Safety and initial efficacy data for the ARC-20 cohort evaluating casdatifan plus cabozantinib in IO-experienced patients will be presented in an oral session at the ASCO Annual Meeting. Fall 2025: More mature data from the cohorts evaluating casdatifan monotherapy in patients who had progressed on both an anti-PD-1 and a TKI therapy. 2026: More mature data from the casdatifan plus cabozantinib cohort and initial data from the new ARC-20 cohorts evaluating casdatifan in the first-line (1L) and IO-experienced settings. Upcoming Study and Cohort Initiations: The PEAK-1 Phase 3 study evaluating casdatifan plus cabozantinib versus cabozantinib in IO-experienced ccRCC is expected to initiate in the second quarter of 2025. Shortly thereafter, Arcus and AstraZeneca expect to initiate a clinical study, part of AstraZeneca’s eVOLVE portfolio, evaluating casdatifan plus volrustomig, AstraZeneca’s investigational anti-PD-1/CTLA-4 bispecific antibody, in IO-naive ccRCC. This study will be operationalized by AstraZeneca. Domvanalimab (Fc-silent anti-TIGIT antibody) plus Zimberelimab (anti-PD-1 antibody) Overall survival data from the Phase 2 EDGE-Gastric study, evaluating domvanalimab plus zimberelimab and chemotherapy in upper gastrointestinal (GI) adenocarcinomas, are expected to be presented in the fall of 2025. The first Phase 3 data readout for domvanalimab plus zimberelimab will be from the ongoing Phase 3 study STAR-221, evaluating domvanalimab plus zimberelimab and chemotherapy in PD-L1 all-comer 1L metastatic upper GI adenocarcinomas and is expected in 2026. CD73-Adenosine Axis: Quemliclustat (small-molecule CD73 inhibitor) and Etrumadenant (A2a/A2b receptor antagonist) Quemliclustat: In the fourth quarter of 2024, Arcus initiated PRISM-1, a Phase 3 trial of quemliclustat combined with gemcitabine/nab-paclitaxel versus gemcitabine/nab-paclitaxel in first-line treatment of metastatic pancreatic cancer. PRISM-1 is recruiting rapidly, with enrollment completion expected by the end of 2025. Etrumadenant: In March 2025, we engaged with the U.S. Food and Drug Administration (FDA) regarding promising results from the ARC-9 study evaluating etrumadenant in third-line metastatic colorectal cancer (mCRC); although the FDA’s feedback confirmed the potential for a registrational path for this program in third-line mCRC, based on our strategic priorities, we are not pursuing a Phase 3 study at this time. Financial Results for First Quarter 2025: Cash, Cash Equivalents and Marketable Securities were $1.0 billion as of March 31, 2025, compared to $992 million as of December 31, 2024. The increase during the period is primarily due to the net proceeds from our underwritten offering in February 2025, partially offset by the use of cash in our research and development activities. We believe our cash, cash equivalents, and marketable securities, together with available facilities, will be sufficient to fund operations through the initial pivotal readouts for domvanalimab, quemliclustat and casdatifan, which include PEAK-1. Revenues were $28 million for the first quarter 2025, compared to $145 million for the same period in 2024. In the first quarter 2025, Arcus recognized $20 million in license and development services revenue related to the advancement of programs, as well as $8 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. Arcus expects to recognize GAAP revenue of between $75 million and $90 million for the full year 2025. Research and Development (R&D) Expenseswere $122 million for the first quarter 2025, compared to $109 million for the same period in 2024. The net increase of $13 million was primarily driven by higher costs in our early-stage development and preclinical program activities, driven by higher enrollment in our Phase 2 studies. The overall increase was partially offset by reduced spend in our late-stage development activities due to lower manufacturing costs driven by the timing of manufacturing activities. Non-cash stock-based compensation expense was $8 million for the first quarter 2025, compared to $10 million for the same period in 2024. For the first quarters 2025 and 2024, Arcus recognized gross reimbursements of $38 million and $37 million, respectively, for shared expenses from its collaborations, primarily the Gilead collaboration. R&D expenses 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) Expenseswere $28 million for the first quarter 2025, compared to $32 million for the same period in 2024. The decrease was primarily driven by the costs incurred to obtain the Third Gilead Agreement Amendment in 2024. Non-cash stock-based compensation expense was $8 million for the first quarter 2025, compared to $10 million for the same period in 2024. Net Losswas $112 million for the first quarter 2025, compared to $4 million for the same period in 2024.

(Nasdaq: KURA), a clinical-stage biopharmaceutical company committed to realizing the promise of precision medicines for the treatment of cancer, today reported first quarter 2025 financial results and provided a corporate update. “In the first quarter of 2025, we achieved a significant milestone with the submission of our first NDA for ziftomenib,” said Troy Wilson , Ph.D., J.D., President and Chief Executive Officer of Kura Oncology . “We are committed to working with FDA to support its review and are strategically advancing our pre-commercial activities to prepare for potential approval for the treatment of adult patients with relapsed or refractory NPM1-mutant AML. Beyond the monotherapy setting, we look forward to sharing data on the combination of ziftomenib with intensive and non-intensive standards of care, while gearing up for two Phase 3 studies in the frontline setting. With a strong pipeline, multiple clinical data readouts expected this year, and a solid financial foundation, we are well-positioned to drive progress across our programs.” Recent Highlights Submission of New Drug Application for ziftomenib to FDA – Kura and Kyowa Kirin Co., Ltd. (Kyowa Kirin) announced submission of the New Drug Application (NDA) for ziftomenib for the treatment of adult patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) with a nucleophosmin 1 (NPM1) mutation to the U.S. Food and Drug Administration (FDA) on March 31, 2025 . From the time of submission, the FDA has a 60-day filing review period, and the Company expects to receive notification from the FDA on this preliminary evaluation in the second quarter of 2025. If Priority Review is granted, it would provide a target FDA review period of six months after NDA acceptance. Abstracts accepted for presentation at ASCO and EHA – In February 2025 , Kura and Kyowa Kirin announced positive topline results from the KOMET-001, the Phase 2 registration-directed trial of ziftomenib in patients with R/R NPM1-mutant (NPM1-m) AML. These data have been accepted for oral presentation at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago and accepted for an encore presentation at the European Hematology Association (EHA) Congress in Milan, Italy . In addition, preliminary clinical data from the Phase 1b expansion cohort evaluating ziftomenib in combination with intensive (7+3) in the frontline setting has been accepted for an oral presentation at EHA. Abstract titles and presentation details can be found on the ASCO and EHA meeting sites at the lift of the respective embargos. Submission of the NDA for ziftomenib has triggered a $45 million milestone payment obligation from Kyowa Kirin – As a result of the NDA submission for ziftomenib, Kura has earned a $45 million milestone payment under the global strategic collaboration agreement between Kura and Kyowa Kirin to develop and commercialize ziftomenib in acute leukemias (Kyowa Agreement). Under the terms of the Kyowa Agreement, Kura received an upfront payment of $330 million in December 2024 and accounting for this $45 million milestone payment, Kura expects to receive up to $375 million in additional, near-term milestone payments. First patients dosed in KOMET-015 trial in GIST – Earlier this week, Kura announced the first patients have been dosed in its KOMET-015 Phase 1 clinical trial of ziftomenib in patients with advanced gastrointestinal stromal tumors (GIST) after imatinib failure. In October 2024 , Kura presented preclinical data at the 36th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona , supporting the potential for ziftomenib in combination with KIT inhibitors for the treatment of GIST. The combination of ziftomenib and imatinib demonstrated robust and durable antitumor activity in imatinib-sensitive (1L) and imatinib-resistant (2L/3L) GIST patient-derived xenograft models. Preclinical data for KO-2806 presented in oral minisymposium session at AACR Annual Meeting – Last month, Kura presented preclinical data for KO-2806, the Company’s next-generation farnesyl transferase inhibitor (FTI), in combination with cabozantinib for the treatment of clear cell renal cell carcinoma at the American Association for Cancer Research (AACR) Annual Meeting in Chicago . These data add to a growing body of preclinical evidence demonstrating the potential of FTIs as companion therapeutic agents to augment the antitumor activities of and to overcome resistance to various targeted therapies. Financial Results Collaboration revenue from our Kyowa Kirin partnership for the first quarter of 2025 was $14.1 million , compared to no revenue for the first quarter of 2024. Research and development expenses for the first quarter of 2025 were $56.0 million , compared to $36.3 million for the first quarter of 2024. General and administrative expenses for the first quarter of 2025 were $22.8 million , compared to $18.2 million for the first quarter of 2024. Net loss for the first quarter of 2025 was $57.4 million , compared to a net loss of $49.5 million for the first quarter of 2024. Net loss for the first quarter of 2025 included non-cash, share-based compensation expense of $7.8 million . This compares to $8.5 million for the same period in 2024. As of March 31, 2025 , Kura had cash, cash equivalents and short-term investments of $658.2 million , compared to $727.4 million as of December 31, 2024 . As adjusted for the $45 million NDA submission milestone payment earned under our collaboration agreement with Kyowa Kirin, Kura had, on a pro forma basis, $703.2 million in cash, cash equivalents and short-term investments as of March 31, 2025 . Based on our current plans, we believe our cash, cash equivalents and short-term investments as of March 31, 2025 will be sufficient to enable us to fund our current operating expenses into 2027 and, combined with anticipated collaboration funding under the Kyowa Agreement, should support our ziftomenib AML program through commercialization in the frontline combination setting.
