flipper et al., I want to ask the naysayers whether is there anyone here who can prove the PFS failed already while at least 98 patients are still alive no matter whether the 248 PFS occurred in 2017 or way before 2016 like they claim. If the PFS failed way before 2016, how is that possible there are 98 or 100 still alive. This 98 alive could have some PFS patients or progression free patients included but if there are some progressed patients in those alive, the literature says rGBM progressed patients live 6 or 8 more months SOC. I want these naysayers to include all these scenarios and still prove PFS failed. If they prove, I will sell all my shares Tuesday that is a very significant quantity. I'm challenging exwannable et al here.
