About this study
Official title: A Phase II, Randomized, Double-Blind, Placebo-Controlled Study of the Safety, Biology, and Clinical Effects of Interferon Gamma-1b Administered Subcutaneously to Patients With IPF Followed by an Open-Label Extension
Study GIPF-002 is a phase 2 study designed to characterize the biologic and clinical effects of IFN-g 1b. The objective of the Study is to characterize the biologic and clinical effects of IFN-g 1b administered to patients with idiopathic pulmonary fibrosis (IPF).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Interferon-gamma 1b in people with Idiopathic Pulmonary Fibrosis, run by InterMune 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?
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 6 Nov 2007. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
change in percent predicted FVC, resting arterial blood gas assessment of alveolar-arterial oxygen gradient, percent predicted DLCO, dyspnea scale, baseline dyspnea index/transition dyspnea index (time frame: 23 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 6 Nov 2007.
