ASCO 2023 | Belzutifan real-world vs clinical trial data: comparing efficacy and safety in VHL-associated tumors

Anusha Chidharla, MBBS, University of Kansas Medical Center, Kansas City, MO, compares the real-world data of belzutifan in VHL-associated tumors versus clinical trial data. The objective response rate (ORR) for associated renal cell cancer was 23%, lower than the clinical trial’s 49%, likely due to shorter follow-up duration (8 months vs. 21 months) and less frequent scans. Safety findings were similar, with common side effects being anemia and fatigue (65-70%). Belzutifan dose was decreased in 30% of our patients (vs. 15% in the clinical trial) due to poorer performance status (ECOG 1-2 vs. ECOG 0). These results highlight the importance of longer follow-up and more frequent scans to capture treatment responses accurately in the real-world setting. This interview took place at the American Society of Clinical Oncology (ASCO) 2023 Annual Congress in Chicago, IL.
