I am involved in study out of UCLA And the primary researcher is involved in a stem cell study funded by Bayer. They are about to start recruitment for a phase 2 trial. Phase 1 was promising. I have announced my interest in being involved in the phase 2 trial, but there is a risk separate from any medical risk of the treatment. There is a chance that any given participant could end up in the control group, which would involve being knocked out for “surgery“ and having a small incision placed on your scalp without having any stem cells injected. Participants will never know if stem cells were actually injected into their brains. This would be done to avoid the placebo effect skewing the study results.
