Overview
TROPION-PanTumor03 will investigate the safety, tolerability, and anti-tumour activity of Datopotamab Deruxtecan (Dato-DXd) as Monotherapy and in Combination with Anticancer Agents in Patients with Advanced/Metastatic Solid Tumours.
Description
This Phase II, open-label, uncontrolled, multicentre study evaluating the efficacy and safety of Dato-DXd as monotherapy (MONO) and in combination with anticancer agents (COMBO) in various advanced solid tumour types.
This study has a modular design, as such a master protocol with independent substudies enables simultaneous evaluation of the safety profile, recommended Phase II dose (RP2D), and efficacy of Dato-DXd in multiple disease populations and treatment combinations. This study will evaluate various solid tumour types, including endometrial cancer (Substudy 1), gastric cancer (Substudy 2), metastatic castration-resistant prostate cancer (mCRPC) (Substudy 3), ovarian cancer (Substudy 4), colorectal cancer (CRC) (Substudy 5), urothelial cancer (Substudy 6) and biliary tract cancer (Substudy 7) in the advanced or metastatic setting. Within each substudy, Dato-DXd will be evaluated as monotherapy (for all substudies except Substudy 2 (Gastric Cancer) and Substudy 6 (Urothelial Cancer) and in combination with approved or novel anticancer agents that may be active in the tumour type being evaluated (for all substudies except Substudy 7).
