Yes, I don't think the path forward is in ET. I think it was just an initial PoC to support moving into MF and other hem onc settings. FWIW, I think they indicated in a prior call that telomeres are very short in MF patients; seemed to suggest the drug might even work better in MF. Also, they said in a prior call that imetelstat produced stat sig PFS results in the NSCLC trial in the subset of patients that had short telomeres. So, may still be hope in solid tumors too.
