About this study

Official title: 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

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.

Read the detailed description

This is a prospective, single center, Phase II biologic effects study of recombinant interleukin-11 (rhIL-11, Neumega) in subjects hemophilia A, moderate or mild; or with Von Willebrand disease unable to take desmopressin acetate (DDAVP) because they are unresponsive, allergic, or DDAVP is contraindicated. The purpose of the study is to establish the biologic efficacy and safety of rhIL-11 in those not able to take DDAVP. Study subjects will include adults, age >= 18 years, with hemophilia A, moderate, defined as factor VIII 0.01-0.04 U/ml, or mild, defined as factor VIII >= 0.05 U/ml; or with VWD defined by low VWF:RCo and /or low VWF:Ag, past bleeding history, and/or family history of VWD. A total of 10-16 subjects will be enrolled in order to assure that 10 complete the study. The specific aims of the study are: 1) to determine the biologic effect of rhIL-11 when given 4 consecutive days; 2) to determine the safety of rhIL-11 when used in subjects with hemophilia A, moderate or mild; or with VWD unresponsive or unable to take DDAVP; and 3) to determine the mechanism of the hemostatic effects of rhIL-11. The biologic efficacy outcomes will be measured by VWD-related coagulation tests (VWF:RCo, FVIII:C, VWF:Ag, closure times) before and after rhIL-11 injection. Safety outcomes will be measured by the number and frequency of adverse events, including fever, headache, fatigue, myalgias, arthralgias, fluid retention, or edema. The mechanism of rhIL-11 hemostatic effect will be measured by VWFmRNA before and after rhIL-11 response. Response to DDAVP following rhIL-11 will also be assessed in those in whom DDAVP is not contraindicated. The study will last up to 1 month per subject, and for 24 months for the entire study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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

    Measured: within 4 days of study drug.

Secondary outcomes (2)
  1. The Frequency of Adverse Events

    Measured: within 11 days of study drug

  2. The Mechanism of Study Drug Effect by VWF mRNA.

    Measured: within 11 days of study drug.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Neumega (Oprelvekin, Interleukin 11, IL-11) in people with Hemophilia A and Von Willebrand Disease, run by University of Pittsburgh at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Mar 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Biologic Effects by Coagulation Tests (time frame: within 4 days of study drug.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00994929, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2016.
