AstraZeneca/BTG abandon CytoFab for sepsis as it fails in Ph IIb

9 August 2012

Anglo-Swedish drug major AstraZeneca (LSE: AZN) has decided to halt any further development of AZD9773 (CytoFab) for the treatment of severe sepsis and/or septic shock, and will hand the asset back to partner BTG (LSE: BTG) following the drugs failure in a Phase IIb clinical trial. The news saw AstraZeneca’s shares fall 2.2% to £30.15 and BTG’s dropping as much a 10% before closing the day up 1.5% at £3.43.

Top-line data from a global double-blind Phase IIb study comparing the efficacy and safety of two doses of AZD9773 with placebo in patients with severe sepsis and/or septic shock, conducted by AstraZeneca did not show any significant improvements versus placebo in respect of the primary endpoint, ventilator-free days, or secondary endpoints including mortality.
