Study Evaluation Rentosertib (INS018_055) Administered Orally in Patients With Idiopathic Pulmonary Fibrosis (IPF)

Official title

A Prospective Phase 3, Randomized, Double-blind, Placebo-controlled, Parallel-group Study Evaluating the Efficacy and Safety of Rentosertib (INS018_055) Administered Orally Over 52 Weeks in Patients With Idiopathic Pulmonary Fibrosis (IPF)

Overview

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of Rentosertib (INS018\_055) administered orally in Patients with Idiopathic Pulmonary Fibrosis. The purpose of this study is to evaluate if Rentosertib (INS018\_055) works to treat patients with Idiopathic Pulmonary Fibrosis in adults. It will also learn about the safety of Rentosertib (INS018\_055). In this study, Rentosertib (INS018\_055) will be compared to a placebo (a look-alike substance that contains no drug) to investigate if Rentosertib (INS018\_055) works to treat Idiopathic Pulmonary Fibrosis.

Interventions

• Drug INS018_055 tablets
  Dosage form: Tablets； Frequency of administration: Orally QD. Other Names: Rentosertib
• Drug Placebo
  Dosage Form: Tablet; Frequency of administration: Orally QD.

Primary outcome measures

• the annual rate of forced vital capacity (FVC; mL) decline over 52 weeks. [Time frame: Weeks 0,4,12,26,39,52]

Secondary outcome measures (5)

• time to first occurrence of any disease progression [Time frame: up to 52 weeks]
• change from baseline to Week 52 in quantitative computed tomography-derived lung fibrosis burden on high-resolution computed tomography(HRCT) [Time frame: week 52]
• change from baseline in quality of life (QoL) as measured by the patient-reported outcomes questionnaires using King's Brief Interstitial Lung Disease questionnaire (K BILD) [Time frame: Weeks 0,4,12,26,39,52]
• change from baseline in QoL as measured by the patient-reported outcomes questionnaires using Living with Pulmonary Fibrosis(L-PF) [Time frame: Weeks 0,4,12,26,39,52]
• change from baseline in hemoglobin-corrected diffusing capacity of the lung for carbon monoxide (DLCO) over 52 weeks [Time frame: Weeks 0, 52]

• not on a treatment with nintedanib or pirfenidone for at least 8 weeks prior to screening visit and during the screening period and do not plan to start or restart antifibrotic therapy.
• Estimated minimum life expectancy of at least 30 months for non-IPF related disease in the opinion of the investigator.
• Male patients and female patients of childbearing potential agree to use highly effective contraception/preventive exposure measures from the time of the first dose of the study drug (for the male patient) or the signing of the ICF (for the female patient) until 90 days after the last dose of the study drug.

Exclusion criteria

• Concurrent participation in another interventional drug, device, or biological investigational research study, or use of an investigational agent within 5 half-lives of the agent (or within 8 weeks when half-life is unknown) prior to screening is not allowed.
• Pulmonary hypertension that is clinically relevant or severe as deemed by the investigator, or other clinically significant pulmonary abnormalities.
• Unstable cardiovascular or other disease within 6 months prior to the screening visit or during the screening period.
• Presence of other clinically significant airway disease that may, in the opinion of the investigator, impact the study safety or efficacy objectives, such as asthma, bronchiectasis, cystic fibrosis, active aspergillosis, active tuberculosis, or other serious concomitant respiratory disorder other than pulmonary fibrosis.
• Acute exacerbation of IPF within 6 months prior to screening visit and/or during the screening period.
• Patients with underlying chronic liver disease (Child Pugh A, B, or C hepatic impairment), hepatic steatosis (including non-alcoholic steatohepatitis and/or other types of fatty liver diseases).
