Aim: To describe overall survival, time to castration resistance and castration resistance-free survival in patients with metastatic castration-sensitive prostate cancer (mCSPC) initiating apalutamide in a US oncology network. Patients & methods: Patients with mCSPC initiating apalutamide on or after 17 September 2019 from an electronic health record-derived deidentified database were included. Patients were followed from apalutamide initiation and were censored at the earlier of end of clinical activity or data availability (31 October 2022). Results: At 12 and 24 months, overall survival rates were 91.0 and 88.3%, rates of castration sensitivity were 85.7 and 72.1%, and castration resistance-free survival rates were 80.2 and 65.9%, respectively. Conclusion: Real-world clinical outcomes of patients with mCSPC treated with apalutamide were comparable to results from the phase III TITAN trial.
This study looked at health outcomes among 176 patients receiving a prostate cancer medication, apalutamide. The average age of patients was 72 years, and approximately two-thirds of patients were White. Two years after starting apalutamide, most patients remained alive and their cancer did not progress.
