NCT00994929

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Biologic Effects by Coagulation Tests

    VWF activity was measured by ristocetin-induced platelet agglutination using a Chronolog aggregometer11-14 and VWF:Ag by "sandwich" ELISA, using anti-VWF antibodies (DakoA082, Carpintera CA). Results were expressed in percent, with normal human plasma pool designated 100%, and severe type 3 VWD plasma used as the negative control

    within 4 days of study drug.

Secondary Outcomes (2)

  • The Frequency of Adverse Events

    within 11 days of study drug

  • The Mechanism of Study Drug Effect by VWF mRNA.

    within 11 days of study drug.

Study Arms (1)

Neumega (Oprelveken, Interleukin 11)

EXPERIMENTAL

Neumega (Oprelveken, interleukin-11 (IL-11) 25 microgram/kilogram by subcutaneou injection once daily for four days, followed on day 4 DDAVP 0.3 microgram/kilogram intravenously 30 minutes after neumega

Biological: Neumega (Oprelvekin, Interleukin 11, IL-11)

Interventions

25 microgram/kg IL-11 by subcutaneous injection once daily for four days, followed by DDAVP 0.3 microgram/kg by intravenous infusion over 30 minutes on day 4, 30 minutes after IL-11.

Also known as: Interleukin-11, IL-11, Oprelvekin

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males or females \>= 18 years of age.
  • A diagnosis of hemophilia A, moderate (FVIII:C 0.01-0.04 U/ml) or mild (FVIII:C \>= 0.05 U/ml); or a diagnosis of VWD, defined by a low VWF:RCo and past bleeding history.
  • For those with VWD, an inability to use DDAVP due to i) unresponsiveness defined as VWF:RCo or FVIII:C level lower than 50 IU/dl or less than a 3-fold increase after 0.3 microgram/kg DDAVP; ii) allergic reactions or seizures; or iii) a contraindication to DDAVP.
  • Willingness to have blood drawn.
  • Willingness to sign informed consent.

You may not qualify if:

  • Presence of other bleeding disorders, acquired Von Willebrand disease, primary thrombocytopenia.
  • Use of immunomodulatory or experimental drugs, or diuretics.
  • Pregnant or lactating women.
  • Previous cardiac disease, congestive failure, arrhythmia (e.g. atrial fibrillation, atrial flutter), hypertension, MI, stroke, or thrombosis.
  • Past allergic reaction to Neumega.
  • Surgery within the past 8 weeks.
  • Inability to comply with study protocol requirements.
  • Concomitant use of antiplatelet drugs, anticoagulants, dextran, aspirin or NSAIDs.
  • Treatment with DDAVP, cryoprecipitate, whole blood, plasma and plasma derivatives containing substantial quantities of FVIII and/or VWF within five days of study.
  • Baseline safety and/or hematology lab values outside the normal limits and/or an EKG indicating an arrhythmia.
