The shares of clinical-stage biotech, Humanigen (HGEN +22.1%), have added more than a fifth on Friday to record the biggest intraday gain since March 2021, after the company’s Chief Scientific Officer, Dale Chappell, disclosed a series of insider purchases. In a regulatory filing on Thursday, Chappell announced the purchase of call options this week, which will grant the right buy several hundred thousands of company shares. Early this month, Humanigen (NASDAQ:HGEN) witnessed a four-day rally after the company’s Chief Executive Cameron Durrant disclosed over twofold rise in his equity stake to 70,000 shares.
