Exelixis Reveals Positive CABINET Trial Findings on Cabozantinib

ALAMEDA, Calif.--Exelixis, Inc. (Nasdaq: EXEL) has recently shared the updated outcomes of its pivotal CABINET trial. This phase 3 study compares cabozantinib (CABOMETYX) against a placebo for patients undergoing treatment for advanced neuroendocrine tumors. The study's exciting results were presented at the European Society for Medical Oncology Congress, showcasing the potential of cabozantinib to serve as a new treatment standard.

About the CABINET Study

The CABINET trial aims to provide a broad evaluation of cabozantinib’s efficacy, encompassing cohorts of patients with advanced pancreatic neuroendocrine tumors (pNET) and advanced extra-pancreatic NET (epNET). With comprehensive participant enrollment from various backgrounds, the study reflects real-world scenarios and diverse patient profiles, contributing to its applicability in clinical practice.

Study Highlights and Efficacy

Dr. Jennifer Chan, lead investigator of the CABINET trial, indicated that cabozantinib showed a meaningful treatment advantage for patients who had previously tried other therapies. According to the latest data, cabozantinib significantly outperformed placebo in improving progression-free survival (PFS). In the pNET cohort, patients experienced profound benefits, with median PFS extending to 13.8 months compared to 4.4 months with placebo.

For the epNET cohort, the results were similarly promising, with a median PFS of 8.4 months for the treatment group against just 3.9 months for the placebo. These findings mark an essential step forward for treating advanced neuroendocrine tumors, which have been historically difficult to manage.

Patient Perspectives and Safety Profile

Dr. Amy Peterson, Chief Medical Officer of Exelixis, echoed the study's significance, emphasizing the urgent need for innovative treatments in this patient population. She expressed hope that cabozantinib's results will pave the way for quicker access to this therapy for patients through ongoing collaboration with regulatory agencies.

The safety profile of cabozantinib was consistent with previous studies, showing no new adverse events. While adjustments to dosing were common due to adverse effects, these are manageable within a clinical setting.

Regulatory Journey and Future Outlook

Currently, Exelixis is pursuing a supplemental New Drug Application (sNDA) for cabozantinib for treating advanced neuroendocrine tumors, having received acceptance from regulatory bodies with a crucial deadline set for April 2025. The early halting of the CABINET study at an interim analysis due to impressive outcomes further underscores the drug's potential.

Insights into Neuroendocrine Tumors

Neuroendocrine tumors, arising from neuroendocrine cells, have seen an increase in diagnosis rates over the past decades, with approximately 161,000 to 192,000 individuals suffering from this condition in the U.S. alone. These tumors can cause significant health issues, and management often requires complex treatment strategies. As cabozantinib addresses this pressing need, its successful incorporation into therapy regimens could significantly enhance patient outcomes.

Commitment to Innovation

Exelixis demonstrates strong commitment to providing advanced therapeutic options, with its flagship product, CABOMETYX, already approved for multiple cancer types, including renal cell carcinoma and hepatocellular carcinoma. Its expansion into treating advanced neuroendocrine tumors reflects the company's dedication to its mission of improving cancer care through research and development.
