Brief Summary

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.

Detailed 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) and in combination with approved or novel anticancer agents that may be active in the tumour type being evaluated (for all substudies except Substudy 1 and Substudy 7).

Number of patients with adverse events and with serious adverse events including abnormal clinical observations, abnormal Electrocardiogram (ECG) parameters, abnormal laboratory assessments and abnormal vital signs that changed from baseline.

PSA50 response (Substudy 3 only)From baseline to PSA response evaluated according to the PCWG3 criteria (up to 12 weeks)

Proportion of participants achieving a ≥ 50% decrease in PSA from baseline to the lowest post-baseline PSA result, confirmed by a second consecutive PSA assessment at least 3 weeks later.

Progression free survival (PFS) response (Substudy 4C only)From baseline to progressive disease or death (approximately 1 year)

PFS is defined as time from start of treatment until progression per RECIST 1.1 as assessed by the investigator or death due to any cause.

Secondary Outcome Measures
NameTimeMethod
Duration Of Response (DoR)From baseline to progressive disease or death (approximately 1 year)

DoR is defined as the time from the date of first documented confirmed response until date of documented progression per RECIST 1.1 as assessed by the investigator or death.

Progression free survival (PFS)From baseline to progressive disease or death (approximately 1 year)

PFS is defined as time from start of treatment until progression per RECIST 1.1 as assessed by the investigator or death due to any cause.

Best percentage change in tumour sizeFrom baseline to progressive disease or death (approximately 1 year)

The best percentage change from baseline in tumour size will be derived as the maximum reduction from baseline or (in the absence of reduction) the minimum increase from baseline.

Pharmacokinetics of Dato-DXd (all substudies) and volrustomig and rilvegostomig (substudy 6): Maximum plasma concentration of the drug (Cmax)At predefined intervals throughout the treatment period (approximately 1 year)

The concentration in plasma will be determined.

Pharmacokinetics of Dato-DXd (all substudies) and volrustomig and rilvegostomig (substudy 6): The time taken to reach the maximum concentration (Tmax)At predefined intervals throughout the treatment period (approximately 1 year)

The concentration in plasma will be determined.
