Could a Pre-Surgery drug slash recurrence in rare joint tumors?

NCT ID NCT07707882

First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time

Summary

This trial investigates whether taking pimicotinib—a drug that blocks a protein driving tumor growth—for 12 weeks before surgery can improve outcomes for people with diffuse tenosynovial giant cell tumor (D-TGCT), a rare but aggressive joint tumor with a high recurrence rate. Participants are randomly assigned to receive either pimicotinib followed by surgery or surgery alone. The study measures how long patients stay free of events like recurrence or progression, aiming to see if the drug-surgery combo reduces the need for repeat operations.

What this could mean

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

Active substance
pimicotinib, a CSF1R inhibitor taken orally, followed by tumor removal surgery
What this could lead to
If successful, this approach could lower the high recurrence rate of diffuse TGCT and reduce the need for repeat surgeries.
What could go wrong
This is a phase 2 trial with only 84 participants, so results may not apply broadly. Pimicotinib can cause side effects like itching, swelling, and fatigue.
