Pimicotinib (ABSK021), an oral, highly potent and selective small molecule inhibitor of colony-stimulating factor 1 receptor (CSF-1R) independently discovered by Abbisko Therapeutics. A number of studies have shown that blocking the CSF-1R signaling pathway could effectively modulate and change macrophage functions, and potentially treat many macrophage-dependent human diseases.[1]

History edit
In December 2023, Abbisko Therapeutics entered into a licensing agreement for pimicotinib in all indications for China rights with Merck KGaA.[2] [3][4]
In April 2023, a global phase III, randomized, double-blind, placebo-controlled, multicenter clinical trial designed to evaluate the safety and efficacy of pimicotinib in patients with tenosynovial giant cell tumor was started (NCT05804045).[5]
Following with pimicotinib for tenosynovial giant cell tumor treatment in phase III, pimicotinib has also entered into a phase II trial in June 2023 for cGVHD treatment in China.[6]
The U.S. Food and Drug Administration (FDA) and the Center for Drug Evaluation (CDE) of NMPA granted pimicotinib breakthrough therapy designation (BTD) for the treatment of tenosynovial giant cell tumor patients that are not amenable to surgery in January 2023 and July 2022, respectively.[7]
Research edit
Pimicotinib is being investigated as a treatment for tenosynovial giant cell tumor,[8][9] chronic graft-versus-host-disease (cGVHD), and pancreatic cancer.
