AACR: First-in-class covalent Werner helicase inhibitor shows clinical proof-of-concept in Phase I trial
University of Texas MD Anderson Cancer Center鈥 RO7589831, a new drug from Roche, is first in a new class of drugs called Werner helicase inhibitors 鈥 Drug works similarly to other DNA damage repair inhibitors, such as PARP inhibitors 鈥 This class of drugs is important because many solid tumor patients with microsatellite instability (MSI) do not benefit from currently approved immunotherapies 鈥 Encouraging early results in this first-in-human trial prompted additional trial cohorts to optimize recommended dose for future clinical development
