Cancer drug cabozantinib takes on rare, Fast-Growing tumors

NCT ID NCT04412629

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests the drug cabozantinib in 35 people with high-grade neuroendocrine tumors that have worsened after at least one prior treatment. These are rare, fast-growing cancers with limited options. The study aims to see if cabozantinib can shrink tumors or slow their growth. Participants take the drug daily on an empty stomach, and researchers track response, survival, and side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Cabozantinib (a targeted cancer drug, also called Cabometyx)

What this could lead to

If it works, this could offer a new treatment option for people with aggressive neuroendocrine tumors that have stopped responding to standard chemotherapy.

What could go wrong

This is a small, early-phase trial (35 people) with no control group, so results may not be definitive. Cabozantinib can cause side effects like fatigue, diarrhea, and high blood pressure.
