A Clinical Pharmacodynamic and Pharmacogenetic Study of OPB-51602 in Patients With Advanced Solid Tumours

OPB-51602 is a novel oral small molecule STAT3 inhibitor developed by Otsuka Pharmaceutical Company, Ltd, and is currently undergoing clinical investigation at the National University Health System (NUHS), Singapore. The proposed correlative pharmacodynamic and pharmacogenetic biomarker study is initiated and funded by the investigators, and will be conducted in conjunction with the extension phase I protocol of OPB-51602 in patients with advanced solid tumours (Study code 266-09-801-01/ DSRB protocol B/09/514). All biomarker and pharmacogenetic samples will be collected, stored and analysed at the local laboratory of the study site (Cancer Science Institute, National University Health System, Singapore, Dr Boon-Cher Goh).
