研究概览
简要总结
- Purpose: A phase 3, randomized, double-blind, placebo-controlled trial to determine the efficacy and safety of 200 µg of recombinant Interferon gamma-1b administered by subcutaneous (SC) injection, compared with placebo, in patients with IPF
- Enrollment: Approximately 800 patients will be enrolled from approximately 80 centers in North America and Europe
- Randomization: 2:1 active-to-placebo ratio
- Duration: at least 2 years active drug or placebo (rescue therapy will be permitted for patients who meet predefined criteria)
详细描述
INSPIRE, the largest and most comprehensive clinical trial ever conducted in IPF, has now completed enrolling patients with mild to moderate IPF. Eligible patients will receive either Interferon gamma-1b or placebo for a minimum of 2 years.

入选标准
- •Clinical symptoms consistent with IPF of >= 3 months duration
- •Diagnosis of IPF within 48 months before randomization
- •Age 40 through 79, inclusive
- •High-resolution computed tomographic scan (HRCT) showing definite IPF. For patients with surgical lung biopsy showing definite or probable usual interstitial pneumonia (UIP), the HRCT criterion of probable IPF is sufficient.
- •For patients aged < 50 years: open or video-assisted thoracoscopic (VATS) lung biopsy showing definite or probable UIP within 48 months before randomization. In addition, there are no features supporting an alternative diagnosis on transbronchial biopsy or bronchoalveolar lavage (BAL) if performed.
- •For patients aged < 50 years: At least one of the following diagnostic findings, as well as the absence of any features on specimens resulting from any of these procedures that support an alternative diagnosis, within 48 months before randomization:
- •Open or VATS lung biopsy showing definite or probable UIP
- •Transbronchial biopsy showing no features to support an alternative diagnosis
- •BAL showing no features to support an alternative diagnosis IPF Disease Severity and Progression
- •FVC >= 55% of predicted value (post administration of bronchodilator)
- •Hemoglobin (Hb)-corrected carbon monoxide diffusing capacity/carbon monoxide transfer capacity (DLCO/TLCO) >= 35% of predicted value
- •At least one of either FVC or Hb-corrected DLCO/TLCO <= 90% of predicted value
- •IPF disease progression evidenced by one or more of the following within the past year and the absence of evidence of improvement in the past year:
- •Absolute decrease of >= 10% in FVC
- •Absolute decrease of >= 15% in DLCO/TLCO
- •Evidence of clinically significant worsening on chest X ray or HRCT
- •Significant worsening of dyspnea
- •Distance walked >= 150 meters (492 feet) with O2 saturation >= 83% on <= 6 L/min of O2 during the 6 Minute Walk Test (6MWT) oxygen titration procedure
排除标准
- •Not a suitable candidate for enrollment or unlikely to comply with the requirements of this study, in the opinion of the Principal Investigator (PI)
- •Forced expiratory volume in the first second (FEV1)/FVC ratio < 0.6 (after administration of bronchodilator)
- •Residual volume (RV) > 140% of predicted (before administration of bronchodilator)
- •History of clinically significant environmental exposure known to cause pulmonary fibrosis (including but not limited to drugs, asbestos, beryllium, radiation, domestic birds)
- •Known explanation for interstitial lung disease, including but not limited to radiation, sarcoidosis, hypersensitivity pneumonitis, bronchiolitis obliterans organizing pneumonia, and cancer
- •Diagnosis of any connective tissue disease, including but not limited to scleroderma, systemic lupus erythematosus, and rheumatoid arthritis
- •Clinical evidence of active infection, including but not limited to bronchitis, pneumonia, sinusitis, urinary tract infection, and cellulitis
- •On a lung transplantation waiting list at time of randomization
- •Medical Exclusions:
- •Any history of malignancy likely to result in death, significant disability, or likely to require significant medical or surgical intervention within the next 3 years. This does not include minor surgical procedures for localized carcinoma (e.g., basal cell carcinoma)
- •Any condition other than IPF which, in the opinion of the PI, is likely to result in the death of the patient within the next 3 years
- •History of unstable or deteriorating cardiac, vascular, or neurologic disease within the previous 6 months, including but not limited to the following:
- •Myocardial infarction, unstable angina pectoris, coronary artery bypass surgery, or coronary angioplasty
- •Congestive heart failure requiring hospitalization
- •Uncontrolled arrhythmias
- •Thromboembolic event (e.g., deep vein thrombosis, pulmonary embolism)
- •Transient ischemic attacks (TIAs) or cerebral vascular accident
- •Any condition, which, in the opinion of the investigator, might be significantly exacerbated by the known side effects, (e.g., flu-like syndrome) associated with the administration of IFN g 1b
- •History of any of the following medical conditions:
- •Multiple sclerosis
- •Seizures within the past 10 years or taking anti seizure medication
- •Severe or poorly controlled diabetes
- •Pregnancy or lactation. Females of childbearing potential are required to have a negative serum pregnancy test before treatment and must agree to practice abstinence or prevent pregnancy by at least a barrier method of birth control for the duration of the study
- •Inability to tolerate nonsteroidal anti-inflammatory drugs (NSAIDS) or acetaminophen (paracetamol)
- •History of ethanol abuse in the past 2 years
- •Known hypersensitivity to IFN-g or closely related interferons or to any component of the study treatment
- •Presence of human immunodeficiency virus (HIV) or chronic viral hepatitis
- •Laboratory Exclusions:
- •Any of the following liver function test criteria above specified limits:
- •Total bilirubin > 1.5 x upper limit of normal (ULN); aspartate or alanine aminotransferases (AST/SGOT or ALT/SGPT) > 2 x ULN; alkaline phosphatase > 2 x ULN; or albumin < 3.0 mg/dL
