– The FDA assigned a Prescription Drug User Fee Act target action date of December 3, 2026 – – Application is based on results from the phase 3 STELLAR-303 pivotal trial, in which zanzalintinib in combination with atezolizumab improved median overall survival and significantly reduced the risk of death versus regorafenib in the intention-to-treat population – ALAMEDA, Calif. --(BUSINESS WIRE)--Feb. 2, 2026-- Exelixis, Inc. (Nasdaq: EXEL) today announced that its New Drug Application (NDA) for zanzalintinib, in combination with atezolizumab (Tecentriq®), has been accepted for review in the U.S. for the treatment of adult patients with metastatic colorectal cancer (mCRC) who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, and, if RAS wild-type, an anti-epidermal growth factor receptor (EGFR) therapy. The Food and Drug Administration (FDA) assigned a standard review with a Prescription Drug User Fee Act target action date of December 3, 2026 . “We are encouraged by this meaningful progress toward addressing the needs of patients with previously treated metastatic colorectal cancer, for whom effective therapies have been limited and treatment outcomes remain poor,” said Dana T. Aftab , Ph.D., Executive Vice President, Research and Development , Exelixis . “Zanzalintinib has the potential to become an important advancement in a challenging treatment landscape, and if approved, zanzalintinib in combination with atezolizumab would provide a novel mechanism of action for patients with previously treated metastatic colorectal cancer. We are deeply grateful to the patients, caregivers and investigators contributing to the clinical research in support of this application, and we look forward to collaborating with the FDA during the review process for our first NDA for zanzalintinib.” The NDA is based on the results of the phase 3 STELLAR-303 pivotal trial, in which zanzalintinib in combination with atezolizumab demonstrated a statistically significant improvement in overall survival (OS) versus regorafenib in the intention-to-treat (ITT) population of patients with previously treated CRC. Detailed results, including OS and progression-free survival (PFS) in the ITT population and in the subset of patients without liver metastases (non-liver metastases, NLM), were presented at the 2025 European Society for Medical Oncology (ESMO) Congress and published in The Lancet . Data pertaining to the other dual primary endpoint, OS in patients without active liver metastases, were immature at the data cutoff, and the trial is proceeding to the planned final analysis for this endpoint, which is expected in mid-2026, based on current event rates. About STELLAR-303 STELLAR-303 (NCT05425940) is a global, multicenter, randomized, phase 3, open-label study that randomized patients 1:1 to either zanzalintinib in combination with atezolizumab (n=451) or regorafenib (n=450). The study includes patients with previously treated non-MSI-high metastatic CRC. The dual primary endpoints of the study are OS in the ITT population and in the NLM subgroup of patients. The ITT population consisted of all randomized patients, regardless of the presence of liver metastases. The NLM subgroup consisted of patients who did not have active liver metastases at baseline as determined by investigator assessment. Secondary endpoints include PFS, objective response rate and duration of response in the ITT population and in the NLM subgroup of patients. More information about the trial is available at ClinicalTrials.gov. About Zanzalintinib Zanzalintinib is a novel oral kinase inhibitor that inhibits the activity of the TAM kinases (TYRO3, AXL, MER), MET and VEGF receptors. These kinases play important roles in oncogenic processes, including tumor cell proliferation, metastasis, angiogenesis, drug resistance and evasion of antitumor immunity. With zanzalintinib, Exelixis sought to build upon its extensive experience with the target profile of cabozantinib, the company’s flagship medicine, while improving key characteristics, including pharmacokinetic half-life. Zanzalintinib is currently being developed for the treatment of advanced solid tumors, including colorectal cancer, kidney cancer and neuroendocrine tumors. Zanzalintinib is an investigational agent that is not approved for any use and is the subject of ongoing clinical trials. About CRC CRC is the third most common cancer and a leading cause of cancer-related deaths in the U.S. 1 Approximately 159,000 new cases will be diagnosed in the U.S. in 2026, with around 55,000 expected deaths from the disease.1 CRC is most frequently diagnosed among people aged 65-74 and is more common in men and in people of non-Hispanic American Indian/Alaska Native descent.2 Nearly a quarter of CRC cases are diagnosed at the metastatic stage, at which point the five-year survival rate is around just 15%.1,2 The liver is the most common site for CRC metastasis. Liver metastases significantly impact survival, with a median five-year survival rate of less than 14% when treated with palliative chemotherapy.3 About Exelixis Exelixis is a globally ambitious oncology company innovating next-generation medicines and regimens at the forefront of cancer care. Powered by drug discovery and development excellence, we are rapidly evolving our product portfolio to target an expanding range of tumor types and indications with our clinically differentiated pipeline of small molecules and biotherapeutics.
