About this study
Official title: Phase II Clinical Efficacy Trial of Recombinant Interleukin-11 (rhIL-11, Neumega) in Subjects With Type 1 Von Willebrand Disease Undergoing Surgery
The purpose of this study is to determine the efficacy and safety of rhIL-11 when given subcutaneously in adults with type 1 von Willebrand disease undergoing elective surgery or major dental procedure. Efficacy will be measured by estimated blood loss, and frequency and severity of bleeding and transfusion requirement during and after surgery. 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 study is a prospective, single-center Phase II trial of Neumega (rhIL-11) in adults with type 1 VWD undergoing elective surgery or major dental procedure. It is anticipated that 10 subjects who meet eligibility criteria will enroll and complete the study. The specific objectives are to determine the efficacy and safety or rhIL-11 during and after elective surgery, and to determine the mechanism of the hemostatic response of rhIL-11.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Neumega (Oprelvekin, Interleukin 11, IL-11) in people with Von Willebrand Disease, run by Margaret Ragni 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 6 inclusion and 14 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: stopped early, as of the sponsor's last update on 11 Jun 2019. 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 7 Nov 2014). 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?
Volume of Surgical Blood Loss (time frame: 4 weeks). The study lists 2 primary outcomes in all. 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 NCT00524225, 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 11 Jun 2019.
