The revised drug efficacy looks dismal on the headline. Admittedly I am no expert but would not touch this.
I have noticed a recent trend for clinical stage biopharma co stocks to recover hugely after a 60 to 70% one day drop, over a period of several months, a lot of them seem to come out one day w/ a revised indication after a catastrophic data point & spike the stock... but it takes some time & surely is not in all cases.
