Exelixis, Inc. (Nasdaq: EXEL) recently announced an update on its ongoing clinical study of XB371, a potential treatment for locally advanced or metastatic solid tumors. The study, which began on August 8, 2025, aims to evaluate the safety and tolerability of XB371, administered as an intravenous infusion. The latest update was submitted on August 27, 2025.

The study is part of Exelixis' ongoing efforts to expand its oncology portfolio. Successful results from this study could potentially enhance the company's offerings in the oncology sector and influence its stock performance. Exelixis has been actively involved in the development of innovative treatments for various types of cancer, including renal cell carcinoma, hepatocellular carcinoma, and differentiated thyroid cancer.

The study of XB371 is particularly significant as it targets a broad range of solid tumors, offering the potential for a more comprehensive treatment approach. The results of the study will provide crucial insights into the safety and efficacy of XB371, which could pave the way for further clinical trials and potential regulatory approvals.

As of the latest update, Exelixis has not released specific details about the interim results of the XB371 study. The company has indicated that it will continue to monitor the study closely and provide further updates as they become available. This approach aligns with Exelixis' commitment to transparency and the importance of thorough clinical data in the development of new cancer treatments.

Exelixis' stock performance has been influenced by its ongoing clinical trials and regulatory approvals. The company's partnership with Ipsen has been particularly notable, with the recent approval of CABOMETYX® (cabozantinib) for the treatment of adult patients with unresectable or metastatic, well-differentiated pancreatic (pNET) and extra-pancreatic (epNET) neuroendocrine tumors who have progressed following at least one prior systemic therapy other than somatostatin analogues [1].
