Alan Tan, MD, assistant professor of Medicine in the division of hematology and oncology at Vanderbilt University Medical Center, discusses upcoming trials that could change the landscape of frontline and adjuvant renal cell carcinoma (RCC) therapy.

Tan says that with the current immunotherapy and tyrosine kinase inhibitor therapy combinations, survival has improved greatly over the past 5 to 10 years, but a plateau has been reached in the frontline metastatic RCC setting in terms of new therapies in the works.

Some newer types of therapy are being investigated in the frontline, such as hypoxia-inducible factor-2α (HIF-2α) inhibitors like belzutifan (Welireg) which is being investigated in combination with pembrolizumab plus lenvatinib in frontline RCC, in the randomized phase 3 LITESPARK-012 trial (NCT04736706), as is the cytotoxic T-lymphocyte–associated protein 4 inhibitor quavonlimab.

Tan also noted that cellular therapies have potential in RCC. At the 2024 International Kidney Cancer Symposium (IKCS), data were presented on chimeric antigen receptor (CAR) T-cell therapies in patients with heavily pretreated RCC, and he suggested these therapies could eventually move to the front line, since patients are willing to try therapies earlier when there is potential for a cure, as with cancer vaccines in the adjuvant setting.

0:10 | We've hit a little bit of a plateau in frontline RCC. We've done so well in the last 5 to 10 years. Yes, we are improving survival, but there's some newer kids on the block; HIF-2α is starting to come into play more and more. I'd love to eventually see how that is moved up closer to adjuvant and frontline metastatic RCC. Of course, we have the LITESPARK-012 trial that we still don’t know results for. I think that is something that could change things quite a bit in the frontline setting in the future. But also, cell therapy is coming. We saw some exciting data at IKCS of CAR T in RCC. If it's efficacious in third, fourth, fifth line, I think this is something that patients would want even in first line or vaccine trials in adjuvant, because they're really willing to risk more if there's a chance for a cure.
