Name: A Phase 2, Randomized, Double-Blind, Placebo Controlled, Parallel Group Study (TRANSFORM) to Evaluate the Efficacy and Safety of GSK3915393 in Participants With Idiopathic Pulmonary Fibrosis (IPF)
Published: 2026-03-15T22:06:20.668290

Resumen

Idiopathic Pulmonary Fibrosis is a chronic lung disease which causes scarring of the lungs and difficulty in breathing. GSK3915393 is a new medicine, which is being tested in participants with IPF for the first time. The study will assess the safety and effectiveness of GSK3915393 in IPF participants.

Criterios de inclusión

Participants with IPF diagnosed within 5 years prior to screening based on the applicable American Thoracic Society (ATS)/ European Respiratory Society (ERS)/ Japanese Respiratory Society (JRS)/ Latin American Thoracic Society (ALAT) Guideline at the time of diagnosis.
Centrally read chest High Resolution Computed Tomography (HRCT) obtained at screening or historical HRCT obtained within 12 months of screening that is consistent with Usual interstitial pneumonia (UIP) or probable UIP (if indeterminate HRCT finding, IPF may be confirmed locally by historical biopsy).
FVC greater than or equal to (\>=) 45 percent (%) of predicted normal.
Diffusing Capacity (of Lung) for Carbon Monoxide (DLCO) \>=25% of predicted normal corrected for hemoglobin (Hb).
Prebronchodilator Forced Expiratory Volume in 1 second (FEV1)/FVC \>=0.7.
If receiving antifibrotics must be on stable dose of nintedanib or pirfenidone for at least 12 weeks prior to screening.
If not receiving approved antifibrotics (pirfenidone or nintedanib) there should be a valid reason for this, such as previous failure, contraindications, failure to meet national or regional eligibility criteria for anti-fibrotic treatment, or participant choice.
If not currently receiving pirfenidone or nintedanib, participant must have stopped pirfenidone or nintedanib for at least 4 weeks prior to screening.
Body weight \>=40 kilogram (kg) and body mass index within the range 18.5-35 kilogram per meter square (kg/m\^2) (inclusive).
A female participant is eligible to participate if a woman of nonchildbearing potential (WONCBP)
Capable of giving signed informed consent

Criterios de exclusión

Participants with Interstitial Lung Disease (ILD) associated with other known causes.
Diagnosis of sarcoidosis or any systemic autoimmune disease (including but not limited to scleroderma, polymyositis/dermatomyositis, systemic lupus erythematosus and rheumatoid arthritis).
Acute IPF exacerbation within 6 months prior to screening and/or during the screening period (investigator-determined).
Clinically significant non-parenchymal lung disease (e.g., asthma, chronic obstructive pulmonary disease, cavitary or pleural diseases) at screening.
Diagnosis of severe pulmonary hypertension (investigator-determined)
Extent of emphysema is greater than the extent of fibrosis according to reported results from the most recent HRCT.
History of previous lung transplant or recent major surgery (investigator-determined) within 12 weeks prior to screening or planned during the trial period. Registration on a transplant waiting list is allowed.
Clinically significant respiratory tract infection (e.g., active tuberculosis, infectious pneumonia, Corona virus disease 2019 \[COVID-19\]) requiring treatment within 4 weeks prior to and/or during the screening period.
Cigarette smoking (including e-cigarettes) either current or within 3 months before screening.
Current or chronic liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
Alanine transaminase (ALT), Aspartate transaminase (AST), Alkaline phosphatase (ALP) greater than (\>) 2x Upper Limit of Normal (ULN) and bilirubin \>1.5x ULN (isolated bilirubin \>1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin less than (\<) 35% at screening).
Clinically significant abnormalities detected on ECG of either rhythm or conduction, a Corrected QT interval (QTc) \>450 millisecond (msec) or QTc \> 480msec for participants with a bundle branch block and/or a pacemaker who are actively ventricularly pacing during the screening ECG.
Participants with pacemakers who are not pacing at the time of the screening ECG should have a non-paced QTc \<450 msec.
Prior/Concomitant Therapy-
Simultaneous use of pirfenidone and nintedanib at screening.
Received systemic corticosteroids equivalent to prednisone \>10 milligrams/day or equivalent within 2 weeks of screening period.
Use of any of the following therapies within 4 weeks prior to screening and during the screening period or planned during the study:
Immunomodulatory therapies, including but not limited to azathioprine, mycophenolate mofetil, methotrexate, tacrolimus, cyclophosphamide, imatinib, Tumour Necrosis Factor -Alpha (TNF- α) inhibitors.
Medications that are under investigation for the treatment of IPF including inhaled treprostinil and Phosphodiesterase-4 (PDE-4) inhibitors. Symptomatic cough therapies are allowed.
Current use of systemic strong and moderate inducers or inhibitors of Cytochrome P450 3A4 (CYP3A4) that cannot be safely discontinued or switched to an alternative agent at least 14 days before randomization.
Current use of systemic CYP3A4 substrates that have a narrow therapeutic index that cannot be safely discontinued or switched to an alternative agent at least 14 days before randomization.
