Abstract
Introduction
Antibody–drug conjugate (ADC) and programmed death-1 (PD-1) inhibitors play crucial roles in the treatment of advanced urothelial cancer (aUC). Increasingly, combination treatment modalities are used in patients with aUC intolerant to platinum-based chemotherapy (PBC). However, clinical evidence on the efficacy and safety of disitamab vedotin plus PD-1 inhibitors for aUC is limited. This case series aims to address this knowledge gap.
Methods
Patients with aUC who were refractory or intolerant to PBC were included. All patients received combined treatment with disitamab vedotin (one of the ADC drugs) and PD-1 inhibitors for at least three cycles. The clinical characteristics of examination, histopathology, outcomes, and adverse events (AEs) were retrospectively collected.
Results
Among this case series, eight patients received disitamab vedotin plus PD-1 inhibitors, of which three achieved a complete response (CR) and two had a partial response (PR). The most common AE was peripheral neuropathy (4/8); the remaining AEs were mostly of mild to moderate severity or unknown and were manageable by supportive care.
Conclusions
Disitamab vedotin combined with PD-1 inhibitors exhibits a favorable efficacy and safety profile, but subsequent larger cohort clinical studies are required to provide evidence-based medicine for the universal application of this regimen.
