Trial Outcomes & Findings for A Pilot Study of Alpha-1-Antitrypsin (AAT) in Steroid Refractory Acute Graft vs Host Disease (NCT NCT01700036)

NCT ID: NCT01700036

Last Updated: 2018-11-27

Results Overview

To estimate the proportion of patients with steroid refractory acute Graft vs Host Disease) GvHD who respond (achieve either PR or CR) to Alpha-1 Antitrypsin (AAT) at a dose of 60mg/kg twice weekly for 8 doses Partial Response (PR) is defined as a decrease of at least one grade in the severity of GVHD without deterioration of any organ systems by d28 of therapy. Complete Response (CR) is defined as the resolution of all manifestations of GVHD by d28 of treatment. All organs must have a Stage 0.
