In comparison, after 1 year on the Merck PD1, 86% of patients with PDL1 positive tumours and 72% of patients with PDL1 negative tumours were still alive as presented at AACR earlier this year.
This is early data, so it is worth checking what the patient populations look like- if one was considerably sicker, that has obviously an influence on the result!
