About this study

Official title: Phase II Clinical Efficacy Trial of Recombinant Interleukin-11 (rhIL-11, Neumega) in Women With Type 1 Von Willebrand Disease and Refractory Menorrhagia

The purpose of this study is to determine the efficacy and safety of rhIL-11, when given subcutaneously for six consecutive months, in reducing menstrual blood loss in women with type 1 von Willebrand disease and refractory menorrhagia. Efficacy will be measured by subjective bleeding severity scale and pictorial bleeding chart. 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 women with type 1 VWD and menorrhagia refractory to estrogen, hormones, or hemostatic agents. It is anticipated that 10 subjects who meet eligibility criteria will enroll and complete this study. All aspects of this study, including the rhIL-11 injections and the screening, hemostatic and safety monitoring, and coagulation testing, are considered experimental. The specific objectives are to determine the efficacy and safety of rhIL-11 in reducing menstrual blood loss in adult women with type 1 VWD during six consecutive menstrual cycles, and to determine the mechanism of the hemostatic response of rhIL-11.

What is being measured

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

  1. >50% Reduction in PBAC (Pictorial Blood Assessment Chart) at 6 Months

    Subjective estimate of blood loss was measured by using a Pictorial blood assessment chart (PBAC) . The PBAC measures scores on a scale where 0 to 100 is normal and greater than 100-200 are abnormal.

    Measured: 6 months

Secondary outcomes (2)
  1. No. of Subjects With Detectable VWF mRNA (Von Willebrand Factor Messenger RNA).

    No. of subjects with detectable VWFmRNA, a measure of IL-11 (interleukin-11) function, specifically increasing VWF synthesis.

    Measured: The time frame is up to 7 months per subject.

  2. No. of Subjects With IL-11 Associated Adverse Events.

    The number of subjects with IL-11 associated adverse events.

    Measured: The time frame is up to 7 months per subject.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 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 4 inclusion and 8 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 31 Jan 2018. 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?

>50% Reduction in PBAC (Pictorial Blood Assessment Chart) at 6 Months (time frame: 6 months). 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 NCT00524342, which also lists 3 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 31 Jan 2018.
