Cabometyx® Trial Highlights Advancements in NET Treatment

Significant Findings from the CABINET Phase III Trial

The recent results from the CABINET Phase III trial have provided promising insights into the efficacy of Cabometyx® (cabozantinib) for patients dealing with advanced neuroendocrine tumors (NETs). The trial demonstrated remarkable benefits of Cabometyx over standard placebo treatments, showing a 77% reduction in the risk of disease progression or death for patients with advanced pancreatic neuroendocrine tumors (pNETs) and 62% for those with advanced extra-pancreatic neuroendocrine tumors (epNETs).

Data Presentation and Future Implications

This promising data was presented during the prestigious European Society for Medical Oncology (ESMO) 2024 Congress and also published in the renowned New England Journal of Medicine. Ipsen has proactively submitted an extension of indication Marketing Authorization to the European Medicines Agency, aiming to expand treatment options for patients suffering from these challenging tumors.

The Need for Effective Treatment Options

Advanced NETs have limited approved treatment options, dictated largely by the site of the primary disease. Unfortunately, there are currently no approved therapies for lung NETs that progress after previous systemic treatment. The challenge lies in the non-specific symptoms of NETs, which often delay diagnoses and complicate subsequent care.

Understanding the Impact of Cabometyx

The CABINET trial’s findings bolster the understanding of Cabometyx's utility in addressing the needs of advanced NET patients. The trial enrolled 298 patients who had experienced disease progression following prior therapies. The outcomes showed superior progression-free survival (PFS) rates favoring Cabometyx, making a strong case for its incorporation into treatment protocols.

CABINET Trial Insights

During a median follow-up period, the PFS was notably higher for those on Cabometyx compared to the placebo group. For pNET patients, the median PFS was recorded at 13.8 months, vastly outperforming the 4.4 months seen in the placebo group. Similarly, in the epNET cohort, the PFS was 8.4 months versus 3.9 months, signaling a significant therapeutic advantage.

Expert Commentary on New Advances

Teodora Kolarova, Executive Director of the International Neuroendocrine Cancer Alliance, highlighted the importance of these findings, emphasizing the ongoing need for research and innovative treatments in the complex landscape of neuroendocrine tumors. These advancements not only bring hope but also reflect the potential for improved quality of life for affected individuals.

About Cabometyx and Its Mechanism

Cabometyx (cabozantinib) operates by inhibiting multiple receptor tyrosine kinases essential for tumor growth and progression. This includes targets such as VEGFRs and MET, which are critical in tumor angiogenesis and metastasis. The collaboration between Ipsen and Exelixis has allowed for this therapy to be explored globally, now with indications for renal cell carcinoma and thyroid cancer.

Continual Global Rise in NETs

A rise in NET diagnoses can be attributed to greater awareness and improved diagnostic techniques. It is estimated that 35 out of every 100,000 individuals worldwide live with NETs today. Despite this increased visibility, the nonspecific nature of NET symptoms often results in significant delays in accurate diagnosis, which can span several years.

Commitment to Patient Care

At Ipsen, the commitment extends beyond just offering treatments like Cabometyx but also involves enhancing the overall understanding and care pathways associated with NETs. The goal is to provide personalized care that considers the unique circumstances of each patient.
