Phase III Ascentar (NOVC) Study Halted - Ineffective Drug or Faulty Trial Design?
November 8, 2007
Novacea Halts ASCENT-2 Trial in Advanced Prostate Cancer | www.therapeuticsdaily.com
Prior studies had suggested an improvement in survival when calcitriol was added to weekly docetaxel. The premature closure of this study ocurred due to an increased death rate in patients receiving the combination of weekly docetaxel compared to q 21 day docetaxel. Faulty trial design, and not necessarily inactivity of the drug, may be to blame for this. Competing trials in this space include the Docetaxel Plus GVAX phase III (Cell Genesys) and the Docetaxel plus Bevacizumab phase III study (US Cooperative Group/Genentech)
