Brief Summary:
This is an open label, Phase One, multicenter study, designed to evaluate the safety, tolerability, to explore the biologic effects, and to explore the clinical effects of the following doses of IW001: 0.1mg/day, 0.5 mg/day, and 1.0 mg/day, when administered once a day orally for 24 weeks in patients with IPF.

Condition or disease Intervention/treatment Phase
Idiopathic Pulmonary Fibrosis Drug: IW001 Phase 1

Detailed Description:
IW001 is a therapeutic designed to treat anti-Col (V)-mediated autoimmune diseases via oral tolerance. With the identification of the specific antigen involved in the autoimmune disease process in IPF, IW001 induced oral tolerance may be an effective treatment. IW001 is taken orally, introduced into the mucosal immune system at the Peyer's Patches in the distal small intestine, where antigen-presenting cells present the antigen to regulatory T cells (Tregs). These antigen-specific Tregs enter the blood stream and traffic to areas where the specific antigen has generated an autoimmune response. Thus, IW001 may produce selective suppression of immune responses against Col (V).

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase One, Open Label, Multi-Dose Study to Evaluate the Safety, Tolerability, and Biologic Effects of Three Doses of IW001 in Patients With Idiopathic Pulmonary Fibrosis (IPF)
Study Start Date : September 2010
Actual Primary Completion Date : October 2012
Actual Study Completion Date : October 2012

Arm Intervention/treatment
Experimental: IW001
Three dose cohorts, 0.1 mg, 0.5 mg, 1.0 mg
Drug: IW001
IW001, 0.1 mg, 0.5 mg, 1.0 mg PO daily for 24 weeks.

Primary Outcome Measures :
  1. To evaluate the safety and tolerability of three doses of IW001 (0.1 mg/day, 0.5 mg/day, and 1.0 mg/day orally) in patients with IPF patients over a 24 week treatment period. [ Time Frame: Monthly during the 24 week treatment period. ]

Secondary Outcome Measures :
  1. To explore the biologic effects of IW001 on T-cell and B-cell reactivity. To explore relationships between Col V reactivity and clinical measures of lung function in patients with IPF. [ Time Frame: Monthly during the 24 week treatment period. ]

      Exclusion Criteria:

  • Patients will be excluded from the study for any of the following:

    1. Concurrent use of systemic corticosteroids or immunosuppressives within 30 days of the Baseline visit.
    2. Chronic NSAID use (limited, i.e., up to 72 hours continuous use of NSAIDs will be permitted during the study), (see Section 9, concomitant medications).
    3. N-acetyl cysteine (NAC) use within 14 days of the Baseline visit.
    4. Any disease, condition or surgery (e.g. inflammatory bowel disease, surgical resection) that may cause malabsorption of IW001.
    5. Known or suspected allergy to bovine products.
    6. Concurrent or prior use of any experimental medication within 30 days of the Baseline visit.
    7. History of smoking within three months prior to the Baseline visit.
    8. Known Hepatitis C or Human Immunodeficiency Virus (HIV) infections.
    9. Evidence of active infection at the Baseline visit.
    10. History of unstable or deteriorating cardiac disease.
    11. Myocardial infarction, coronary artery bypass, or angioplasty within 6 months of the Baseline visit.
    12. Unstable angina pectoris or congestive heart failure requiring hospitalization within 6 months of the Baseline visit.
    13. Uncontrolled arrhythmia.
    14. Patient has a history of illicit drug or alcohol abuse in the past year or current evidence of such abuse or addiction in the opinion of the Investigator.
    15. Patient has positive findings on urine drug screen.
    16. Any other clinically significant illness, that, in the opinion of the Investigator, might put the patient at risk of harm during the study or might adversely affect the interpretation of the study data.
