Senhwa was invited to present positive topline results from their global phase II trial,evaluating the combination of Silmitasertib plus Gemcitabine/Cisplatin compared to Gemcitabine/Cisplatin alone in the frontline treatment of patients with Cholangiocarcinoma.The trial met its primary endpoint at a pre-specified interim analysis demonstrating a statistically significant and clinically meaningful improvement in progression-free survival (PFS) (P<0.05),and was stopped early because superior efficacy was demonstrated. PFS was assessed by an independent statistician.
