Excerpt:
Histologies that were TMB-high included melanoma (N = 6), bladder cancer (N = 2), cutaneous squamous cell carcinoma (N =2), glioblastoma (N = 1), breast cancer (N = 1), basal cell carcinoma (N = 1), esophageal carcinoma (N = 1), and prostate cancer (N = 1)...All patients were treated with either PD-1/L1 or CTLA4 checkpoint blockade (some received a combination of these agents)...The median PFS for TMB-high tumors compared to TMB-Low to -Intermediate tumors was 26.8 months vs. 4.3 months. (P = 0.0173, HR 0.42 [95% CI 0.22–0.77])...
