Hi Phil - thanks for that, it's a phase 1 trial and as far as I can work out, they're establishing the effective dose of the medication in humans, after successful tests in animals and in vitro.
Because it's an early trial they tell me I'll definitely get the drug (possibly in combination with another), they haven't got to the blind-testing phase etc yet.
I'll be meeting with the team in the coming days and will update with anything significant ...
