Description
Sources: https://www.cancer.gov/publications/dictionaries/cancer-drug?cdrid=659167 | http://www.prnewswire.com/news-releases/fda-grants-breakthrough-therapy-designation-for-daiichi-sankyo-and-plexxikons-investigational-csf-1r-inhibitor-pexidartinib-plx3397-in-tenosynovial-giant-cell-tumor-300169556.html

Pexidartinib (PLX3397) is a small-molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Pexidartinib binds to and inhibits phosphorylation of stem cell factor receptor (KIT), colony-stimulating factor-1 receptor (CSF1R) and FMS-like tyrosine kinase 3 (FLT3), which may result in the inhibition of tumor cell proliferation and down-modulation of macrophages, osteoclasts and mast cells involved in the osteolytic metastatic disease. FDA has granted Breakthrough Therapy Designation to pexidartinib (PLX3397) for the treatment of tenosynovial giant cell tumor (TGCT) where surgical removal of the tumor would be associated with potentially worsening functional limitation or severe morbidity. In addition to Breakthrough Therapy Designation, pexidartinib (PLX3397) has been granted Orphan Drug Designation by FDA for the treatment of pigmented villonodular synovitis (PVNS) and giant cell tumor of the tendon sheath (GCT-TS). It also has received Orphan Designation from the European Commission for the treatment of TGCT.

The observed similar M/P ratio indicates that pexidartinib had no impact on the CYP2C19 pathway.

In Vitro Use Guide

In vitro, a population doubling assay showed that the IC50 of pexidartinib (PLX3397) for CSF1-induced bone marrow–derived macrophages (M(CSF1)) was 22 nM. Marked suppression of CSF-1R phosphorylation in M(CSF1) cells could be achieved with PLX3397. In contrast, the same doses of PLX3397 showed no antiproliferation effect on Hepa1-6, MHCC97-H, HCCLM3, HepG2, HUVEC, T cells, fibroblasts cells, and CSF2-induced bone marrow–derived macrophages.
