About this trial
This is a dose escalation, and dose expansion study of T-DXd plus hyaluronidase administered subcutaneously, to assess the safety, tolerability, PK and efficacy of SC T-DXd plus hyaluronidase in participants with metastatic solid tumors.

Treatment groups
Trial outcomes
Primary outcomes
Number of Participants Experiencing a Treatment Emergent Adverse Event (TEAE)
TEAEs are defined as those Adverse Events (AEs) with start or worsening date during the on-treatment period (from the first dose date of trial intervention to 21 days after the last dose date of trial intervention).
Area Under Curve (AUC)
Number of Participants with Dose limiting toxicities (DLT) During the Dose-Escalation Phase
Secondary outcomes
Percentage of Participants with Anti-Drug Antibody (ADAs)
Overall Response Rate (ORR)
ORR is defined as the proportion of participants who achieved a best overall response (BOR) of confirmed complete response (CR) or confirmed partial response (PR), as assessed by investigator per RECIST v1.1
Disease Control Rate (DCR)
DCR is defined as the proportion of participants with a BOR of confirmed CR, confirmed PR, or stable disease (SD) per RECIST v1.1.
