Phase II Biologic Effects Study of Recombinant Interleukin-11 (rhIL-11, Neumega) in Subjects With Moderate or Mild Hemophilia A, or Von Willebrand Disease Unable to Use DDAVP
In Brief
A Phase 2 clinical trial evaluating Neumega (Oprelvekin, Interleukin 11, IL-11) for Hemophilia A and Von Willebrand Disease. Completed, enrolled 9 participants across 1 site.
Detailed Summary
The purpose of this study is to determine the biologic efficacy and safety of rhIL-11 when given subcutaneously in adults with moderate or mild hemophilia A or Von Willebrand disease unresponsive to DDAVP. Biologic efficacy will be measured by the number and percent increase of VWD coagulation tests (FVIII:C, VWF: Ag, VWF: RCo, closure time, APTT, and VWF multimers) to the normal range, or at least to 1.5-3 time baseline, following dosing of rhIL-11 when given daily for 4 days, and boosted by DDAVP infusion on day 4, in those in whom DDAVP is not contraindicated. Safety will be measured by the frequency of adverse events, including fever, headache, fatigue, myalgias, arthralgias, fluid retention, or edema.
