Sprifermin
Sprifermin (INN) (developmental code name AS-902330), also known as recombinant human fibroblast growth factor 18 (rhFGF18), is a recombinant form of human fibroblast growth factor 18 (FGF18)[1]:45 which is under development by Merck and Nordic Bioscience for the treatment of osteoarthritis.[2] As a recombinant form of FGF18, sprifermin is a potent agonist of the FGFR2 and FGFR3.[3][4]

As of 2017, the drug is in phase II clinical trials for the treatment of osteoarthritis.[2][5]
2019 outcomes of phase 2 clinical trial for KOA, shows improvement in cartilage thickness, but fails to satisfy tests like the WOMAC, therefore failing to satisfy its primary end points.[6]
However in some subgroups where cartilage thickness is of specific concern, clinical significance might be achieved.[7]
