On 23-Nov-2010, B1131001 (CVX-060-102) was closed to enrollment due to emerging clinical data which led to a re-assessment of the strategic goals of the PF-04856884 program. The study enrolled the Phase 1b portion only. Subsequently, on 25-Oct-2012, due to data safety signals in a separate clinical trial with PF-04856884 (CVX-060), all PF-04856884 studies were discontinued and ongoing patients on B1131001 were permitted to remain on study at a reduced PF-04856884 dose if determined to have been deriving clinical benefit.
