This is an interventional treatment trial for Idiopathic Pulmonary Fibrosis Read More

Inclusion Criteria:

• Subject's written informed consent obtained prior to any study-related procedure.
• Males or females, of any race, aged between 40 and 80 years of age, inclusive.
• Body weight ≥ 45 kg.
• Diagnosis of IPF as defined by current American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Latin American Thoracic Association guidelines. Diagnosis of IPF must be within the past 5 years prior to enrolment, and in the opinion of the Investigator, has been stable for at least 3 months.
• Subjects not receiving any IPF treatment (including subjects with previous use of antifibrotic treatment that has been stopped) or receiving well-tolerated standard of care approved treatments at a stable dose for at least 8 weeks prior to screening (nintedanib or pirfenidone) and it is anticipated the dose will remain unchanged throughout the study.
• Forced vital capacity (FVC) ≥ 50% of predicted and ratio of forced expiratory volume in the first second (FEV1)/FVC ≥ 0.7 at screening and prior to randomization.
• Diffusing capacity of the lung for carbon monoxide (DLCO; corrected for haemoglobin) from 35% to 79% of predicted, inclusive at screening and prior to randomization.
• Able to understand the study procedures and the risks involved.
• Male and Female subjects following contraceptive requirements detailed in the study protocol.

Exclusion Criteria:

• History of respiratory tract infection within 2 months prior to screening and up to Day 1 of the study.
• History of acute exacerbation of IPF within 3 months prior to screening and up to Day 1 of the study
• Active diagnosis of lung cancer or a history of lung cancer.
• Active cancer or a history of cancer (other than lung cancer) with less than 5 years disease free survival time (whether or not there is evidence of local recurrence or metastases).
• Infiltrative lung disease other than IPF
• Subjects exhibiting unhealed wounds or foot ulcers or have known history of wound healing complications.
• Chronic heart failure categorized as New York Heart Association Class II, III, or IV; clinical diagnosis of cor pulmonale requiring specific treatment; or severe pulmonary hypertension
• Currently receiving, or have received, a systemic corticosteroid, immunosuppressant, cytotoxic therapy, vasodilator therapy for pulmonary hypertension, or unapproved or investigational treatment for IPF within 4 weeks prior to screening or prior to randomization.
• Coronavirus disease-2019 (COVID-19) vaccine at least 7 days before dosing. Any systemic symptoms (e.g. myalgia, fever, chills, fatigue, etc.) after COVID-19 vaccine should subside at least 2 days before the Day 1 visit.
• Documented COVID-19 diagnosis within the last 8 weeks or which has not resolved within 14 days prior to screening or before treatment.
• Known intolerance and/or hypersensitivity to any of the excipients contained in the formulation or any other substance used in the study.
• History of allergic or anaphylactic reaction to human, humanised, chimeric, immunoglobulins (Igs), or murine monoclonal antibodies.
• Clinically relevant abnormal laboratory values (clinical chemistry and haematology) at screening suggesting an unknown disease and requiring further clinical investigation or which may impact the safety of the subject or the evaluation of the study results according to Investigator judgement. .
• Pregnant or lactating women.
