New hope for neuroendocrine tumors: zanzalintinib takes on everolimus
NCT ID NCT06943755
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 9 times
Summary
This study compares a new drug, zanzalintinib, to the current standard drug everolimus in people with advanced neuroendocrine tumors that have already been treated. The goal is to see which drug better slows tumor growth. About 440 participants will be randomly assigned to one of the two treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- zanzalintinib
- What this could lead to
- If it works, this could offer a new treatment option for people with advanced neuroendocrine tumors that have stopped responding to other therapies.
- What could go wrong
- This is an early-to-mid-stage trial, so results are not guaranteed. The new drug may not be more effective than the existing drug everolimus, and side effects are possible.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Key Inclusion Criteria: * Histologically confirmed, locally advanced/unresectable or metastatic, well-differentiated Grade 1, 2, or 3 NETs of pancreatic origin or extra-pancreatic origin. * Allowed prior lines of therapy, based on the site of NET and functional status. * Documented radiographic disease progression per RECIST 1.1, as assessed by the Investigator based on imaging assessments (computed tomography \[CT\] or magnetic resonance imaging \[MRI\]) within 12 months before randomization. * Measurable disease according to RECIST 1.1 as determined by the Investigator. * Archival tumor tissue is required, if available. If archival tumor tissue is not available, a fresh biopsy may be submitted if it can be safely and feasibly obtained. Every attempt should be made to provide tumor tissue. Key Exclusion Criteria: * Histologically confirmed neuroendocrine carcinomas (including small cell lung cancer), medullary thyroid cancer, pheochromocytoma, paraganglioma, Merkel cell carcinoma, and mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN). * Prior treatment with a vascular endothelial growth factor receptor (VEGFR) -targeting tyrosine kinase inhibitor or a mammalian target of rapamycin (mTOR) inhibitor. * Systemic chemotherapy and any liver-directed or other ablative therapy within 4 weeks before randomization. * Systemic radionuclide therapy within 6 weeks before randomization. * Radiation therapy for bone metastases within 2 weeks, any other radiation therapy, except as indicated above, within 4 weeks before randomization. Note: Other protocol defined Inclusion/Exclusion criteria may apply.
