Principal investigator is Dr. Tim Cloughesy. He is leading the phase 3 GLOBE study. The shorts' accusations about data all falls apart when you look at Cloughesy's background.
Cloughesy is one of the leaders in the area of malignant gliomas. He is the Director of the UCLA Neuro-Oncology Program. He's not going to put his reputation on the line for some biotech company if some of the stuff the shorts claim are true.
