Several clinical trials are ongoing currently with compounds targeted for FGF2; a phase III study was designed to compare the safety and efficacy of a multi-tyrosine kinase inhibitor, masitinib, in combination with bortezomib and dexamethasone to placebo in combination with bortezomib and dexamethasone in patients with relapsing multiple myeloma. This evidence concerns the gene FGF2 and plasma cell myeloma.
