Misleading PR
Hi all, I just looked into the Brayer study.
The SLS phase 2 headline says there was a 64% immune response rate, but I realized that's a bit misleading because it was for CR1. Tsirigotis presentation also made it look like those numbers were for CR2, but the actual brayer paper shows that only 20% (2/10) of the CR2 cohort actually had an immune response.
I know the brayer study is messy but it makes me imagine what else they could have been a bit misleading with. Like the enrolment population?
It also makes me question the authenticity of Dr Tsirigotis, as a physician and researcher I’m pretty sure he would have been aware of this.
