BI 6727 (Volasertib) Monotherapy Phase I Trial in Japanese Patients With Advanced Solid Tumours

This open-label phase I dose escalation trial, 1230.15, is the first trial with Volasertib in Japanese advanced cancer patients. The trial will investigate the maximum tolerated dose (MTD), safety, tolerability, and preliminary efficacy of this specific polo-like kinase 1 (Plk1) inhibitor in advanced cancer patients.
