About this study
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)
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing INS018_055 tablets in people with Idiopathic Pulmonary Fibrosis, run by InSilico Medicine Hong Kong Limited at 47 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 47 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Qinhan Chen (+86 021-50831718, Insilico-Clinicaltrial@insilico.ai), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the annual rate of forced vital capacity (FVC; mL) decline over 52 weeks. (time frame: Weeks 0,4,12,26,39,52). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Oct 2026.
