NCT00957242

Brief Summary

This study will test the effectiveness of warfarin in patients with IPF. Approximately 256 patients will be randomized 1:1 to either warfarin or placebo. Patients will return at week 1 for a safety review and every 16 weeks for 48 weeks. The primary endpoint in the study is the time to either death, non-bleeding/non-elective hospitalization, or a drop of greater than 10% in forced vital capacity (FVC) from baseline.

Eligibility Criteria

Age35 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of IPF
  • Age between 35 and 80, inclusive
  • Capable of understanding and signing consent
  • Progression despite conventional therapy (standard of care). Progression defined as:
  • Worsened dyspnea
  • FVC decreased by \>=10% predicted OR
  • DLCO decreased by \>=10% absolute OR
  • Reduction of oxygenation saturation \>= 5% with or without exertion on a constant oxygen (02) administration
  • Worsened radiographic findings (chest x-ray or high-resolution computed tomography)

You may not qualify if:

  • Current enrollment in another investigational protocol
  • Current treatment with an investigational drug (i.e., participating in an active investigational drug protocol) within the previous 4 weeks or 5 times the half-life of the investigational agent, whichever is longer, prior to screening
  • Subject is actively listed for lung transplantation at the time of enrollment
  • Subjects who will not be able to perform/complete the study, in the judgment of the physician investigator or coordinator, for at least 3 months. For example:
  • Subject has current signs or symptoms of severe, progressive or uncontrolled comorbid illnesses such as: renal, hepatic, hematologic, gastrointestinal, endocrine, cardiac, neurologic, or cerebral disease, or any laboratory abnormality which would pose/suggest a risk to the subject during participation in the study.
  • Subject has a transplanted organ requiring immunosuppression
  • History of substance abuse (drugs or alcohol) within the 2 years prior to screening, history of noncompliance to medical regimens, inability or unwillingness to perform INR monitoring, or other condition/circumstance that could interfere with the subject's adherence to protocol requirements (e.g. psychiatric disease, lack of motivation, travel, etc).
  • Have any known active malignancy or have a history of malignancy within the previous 2 years (an example of an exception is a non-melanoma skin cancer that has been treated with no evidence of recurrence for at least 3 months) that might increase the risk of bleeding.
  • Estimated life expectancy \< 12 months due to a non-pulmonary cause.
  • Subject has another respiratory disease that is predominant (as judged by the PI) in addition to IPF.
  • Current anticoagulation therapy with warfarin
  • Increased risk of bleeding (e.g. uncorrectable inherited or acquired bleeding disorder)
  • Platelet count \< 100,000 or hematocrit \< 30% or \> 55%
  • History of severe gastrointestinal bleeding within 6 months of screening
  • History of cerebral vascular accident (CVA) within 6 months of screening
  • +6 more criteria
