We evaluated the relation between FOLH1 expression and angiogenesis, as well as clinical outcomes, in two prior large trials of IO and/or TKI in m-ccRCC....In COMPARZ, patients with high FOLH1 expression (> median expression value) had improved OS and PFS compared to those with low FOLH1 expression in the sunitinib, but not pazopanib, arm (Log-rank p = 0.014 and 0.024 vs 0.44 and 0.29, respectively)….In IMmotion 150, patients with complete/partial response to sunitinib had significantly higher expression of FOLH1 than non-responders (mean score 30 vs 24, Wilcoxon p = 0.049)…
