Kevin McCormack discusses encouraging phase II trial news at his blog:
The treatment seemed to start showing effectiveness after two weeks and at three months…
“As of 90 days post-treatment, Kris has gained significant improvement in his motor function, up to two spinal cord levels. In Kris’ case, two spinal cord levels means the difference between using your hands to brush your teeth, operate a computer or do other things you wouldn’t otherwise be able to do, so having this level of functional independence cannot be overstated.”
One commenter asks why the trial does not include those who were in accidents many years ago and Kevin McCormack responded:
The plan is for Asterias to first test and show it is safe and works in this particular group of patients. Then, if that clinical trial is successful, to expand the number of people who can try it including someone with an older injury.
Trials often include patients from groups where the trial is most likely to be successful before a later trial expands to include harder cases.
