LITESPARK-012

Adding belzutifan to first-line lenvatinib-pembrolizumab did not deliver, a reminder that later-line success does not guarantee first-line benefit.

Results presented at ASCO GU 2026 fell short of the trial's goals for the belzutifan-containing triplet versus the lenvatinib-pembrolizumab doublet. Belzutifan's role in RCC is therefore later line and adjuvant (LITESPARK-022), not first-line intensification.
