Journal

Asia-Pacific Journal of Clinical Oncology

Year

2025

Materials & Methods

Data from patients with locally advanced or metastatic UC who received ≥ 1 dose of avelumab 1L maintenance treatment between September 2021 and January 2023 were obtained retrospectively. Patient and treatment characteristics, best response to treatment, and safety were assessed.

Results

Data were provided from 13 patients treated at 9 hospitals in Malaysia. Seven patients (53.8%) were female, and ECOG performance status prior to 1L chemotherapy was 0–1 in 11 patients (84.6%) and 2 in 2 patients (15.4%). Chemotherapy included cisplatin in 6 patients (46.2%) and carboplatin in 7 patients (53.8%), and the best response was complete response in 1 patient (7.7%), partial response in 7 patients (53.8%), and stable disease in 5 patients (38.5%). The median duration of avelumab treatment was 9 months, with treatment ongoing in 4 patients (30.8%) at last follow-up. The objective response rate was 30.8% and an additional 5 patients (38.5%) had stable disease as the best response. Median PFS was 10.4 months. Reasons for discontinuation were disease progression in 8 patients (61.5%) and patient withdrawal in 1 patient (7.7%). Treatment-related adverse events occurred in 3 patients (23.1%) and were grade 2 in 1 patient (7.7%) and grade 1 in 2 (15.4%).

Conclusion

Data from this small EAP population support the use of avelumab 1L maintenance treatment in patients with advanced UC in Malaysia.

Clinical trials are part of research studies involving patient volunteers that are conducted to find safe and effective treatments for a variety of health conditions. They are critical to the advancement of medicine and improving patient health. Participating in clinical trials offers patients the opportunity to try new and effective treatments that could potentially improve their condition while taking part in vital research that can benefit many future patients.

In Pantai Hospital Kuala Lumpur, clinical trials are carried out under our Clinical Research team.
