Deciphera Pharmaceuticals Inc. CEO Steven Hoerter told BioWorld Asia the FDA approval of Turalio (pexidartinib) from Daiichi Sankyo Co. Ltd. last week "leaves a lot of headroom for efficacy," given the response rate of about 40%. "One of the most significant concerns that the FDA had was hepatotoxicity, which is an off-target effect," he added, so the approval came with "some fairly onerous monitoring requirements."
