"Humanigen initiated with an Outperform at Oppenheimer Oppenheimer analyst Kevin DeGeeter initiated coverage of Humanigen with an Outperform rating and $30 price target."
That $30 PT pairs nicely with the options action today..
Also interesting the expiration corresponds with this timeline stated in a reuters article today:
EU plans faster approval, new joint purchases of COVID-19 drugs
"The Commission also said it would draw up a portfolio of 10 potential COVID-19 therapeutics and will identify the five most promising ones by June"
