GB28547 Lebrikizumab in IPF

Overview

Status: Not yet recruiting
Keywords: IPF , Idiopathic Pulmonary Fibrosis , Pulmonary Disease
IRB Number: 00066033
Specialty: Pulmonary, Pulmonary
Sub Specialties: Pulmonary Fibrosis, Pulmonary

Brief Summary

  

The primary efficacy objective for this study is as follows:

• To evaluate lebrikizumab compared with placebo in patients with idiopathic pulmonary fibrosis (IPF), as measured by progression-free survival (PFS) defined as the time from study treatment randomization to the first occurrence of any of the following events:

• Death from any cause

• Non-elective hospitalization from any cause

• A decrease from baseline of  ≥ 10% in forced vital capacity (FVC) (L) (relative change)

 

The secondary efficacy objectives for this study are as follows:

• To evaluate the efficacy of lebrikizumab compared with placebo in patients with IPF on the basis of pulmonary function, diffusion capacity, death, non-elective hospitalization from any cause, and acute IPF exacerbations

• To evaluate the efficacy of lebrikizumab compared with placebo in patients with IPF on thebasis of distance walked in 6 minutes and health-related quality of life

 

The safety objectives for this study are as follows:

• To evaluate the safety of lebrikizumab compared with placebo in patients with IPF

 

The pharmacodynamic (PD) objectives for this study are as follows:

• To characterize the pharmacokinetics of lebrikizumab in patients with IPF

The exploratory objectives for this study are as follows:

• To evaluate the efficacy of lebrikizumab compared with placebo in patients with IPF on the basis of changes in: use of supplemental oxygen therapy, the number of respiratory hospitalizations, acute IPF deterioration, quantitative lung fibrosis (QLF) on high resolution computed tomography (HRCT), and in patient reported outcomes

• To evaluate potential prognostic and predictive serum and whole blood RNA and DNA biomarkers associated with IPF

Inclusion Criteria

Patients must meet the following criteria for study entry: 
• Able and willing to provide written informed consent and to comply with the study protocol 
 
• Age ≥40 years at Visit 1 
 
• Have a definite IPF diagnosis according to the 2011 ATS/ERS/JRS/ALAT consensus statement on IPF within the previous 4 years from time of screening and confirmed at baseline. 
 
• Have a central review assessment of a screening HRCT performed during the screening period or within 6 months prior to the start of screening. 
 
• All patients who have undergone a SLB as part of their initial workup should have pathology slides sent in for SLB central review assessment.
 
• Eligibility will be determined based on Table 1: 
Table 1 Combined High Resolution Computed Tomography and Surgical Lung Biopsy Eligibility Assessment 
    SLB Assessment SLB Assessment SLB Assessment SLB Assessment SLB Assessment SLB Assessment
    Definite UIP Probable UIP Possible UIP Non-Classifiable fibrosis Inconsistent with UIP No SLB
HRCT Assessment Definite UIP Eligible Eligible Eligible Eligible Not Eligible Eligible
HRCT Assessment Possible UIP Eligible Eligible Not Eligible Not Eligible Not Eligible Not Eligible
HRCT Assessment Inconsistent with UIP Not Eligible Not Eligible Not Eligible Not Eligible Not Eligible Not Eligible

HRCT = high resolution computed tomography; SLB= surgical lung biopsy; UIP= usual interstitial pneumonitis 

 
Additionally, patients must meet the following criteria for study entry: 
• FVC ≥40% and ≤90% of predicted at screening 
 
• Stable baseline lung function as evidenced by a difference of <10% in FVC (L) measurements between screening and Day 1/Visit 2 prior to randomization 
 
• DLCO ≥25% and ≤90% of predicted at screening 
 
• Ability to walk ≥100 meters unassisted in 6 minutes

 

Exclusion Criteria

Patients who meet any of the following criteria will be excluded from study entry: 
 
• History of a severe allergic reaction or anaphylactic reaction to a biologic agent or known 
hypersensitivity to any component of the lebrikizumab injection 
 
• Evidence of other known causes of interstitial lung disease (ILD) (e.g., domestic and occupational environmental exposures, connective tissue disease, and drug toxicity)  
 
• For patients having one or more positive serologies (antinuclear autoantibodies [ANA], rheumatoid factor [RF], or CCP [anti-citrullinated protein antibody]) a relevant work-up should have been performed to exclude connective tissue disease (CTD). 
 
• Lung transplant expected within 12 months of screening 
 
• Evidence of clinically significant lung disease other than IPF (e.g., asthma or chronic obstructive pulmonary disease [COPD]) 
 
• Post bronchodilator forced expiratory volume in 1 second (FEV1)/FVC ratio <0.7 at screening 
 
• Positive bronchodilator response evidenced by an increase of ≥12% predicted and 200 mL increase in either FEV1 or FVC 
 
• Any clinically significant medical disease (other than IPF) that is associated with an expected survival of <12 months, likely to require a change in therapy during the study, or likely to impact the ability of the patient to participate in the study in the opinion of the investigator, or impact the study efficacy or safety assessments 
 
• Requirement for continuous medical care and assistance, or limited ability to self care that would impact the ability of patient to participate in the study or to perform the study-related assessments 
 
• Class IV New York Heart Association chronic heart failure or historical evidence of left ventricular ejection fraction <35% 
 
• Hospitalization due to an exacerbation of IPF within four weeks prior to, or during screening 
 
• Known current malignancy or current evaluation for a potential malignancy
