## TL;DR

Cabozantinib tripled the time without progression in neuroendocrine tumours that had outgrown other treatments, leading to a 2025 approval.

## Summary

CABINET, Alliance trial A021602, NCT03375320, sponsored by the Alliance, the NCI and Exelixis and reported in the New England Journal of Medicine in 2024, showed that cabozantinib roughly tripled the time without progression in neuroendocrine tumours that had outgrown other treatments, leading to FDA approval in March 2025. It randomised 298 patients in separate pancreatic and extra-pancreatic cohorts to cabozantinib or placebo and met its primary progression-free survival endpoint in both, with an ESMO 2025 subgroup analysis showing a large reduction in progression risk in lung and thymic tumours. OnCo links it to neuroendocrine tumours, cabozantinib and the Alliance for Clinical Trials in Oncology. Whether cabozantinib's benefit holds against, or in sequence with, radioligand therapy is the open question.
