About

Tenosynovial giant cell tumor is a benign but locally aggressive growth that forms in joints and tendon sheaths, often causing pain, swelling, and limited movement. Pimicotinib is an oral drug designed to block a specific cellular signal (CSF-1R) that the tumor cells rely on to survive and multiply. By interrupting this signal, pimicotinib may shrink these tumors and alleviate the symptoms that interfere with joint function.
