What is being measured

The primary outcome is the main question the study is designed to answer.

The incidence of treatment-emergent adverse events (TEAEs)
An Adverse Event (AE) is any event, side-effect or any untoward medical occurrence in a clinical study participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs are AEs that occur following the start of treatment.
Measured: Approximately 170 days.
The severity of treatment-emergent adverse events (TEAEs)
Severity of TEAEs (Grade 1 to 5) will be assessed based on NCI-CTCAE V5.0.
Measured: Approximately 170 days.
The incidence of serious adverse events (SAEs)
A serious adverse event (SAE) is defined as an AE occurring during any study phase and at any dose of medicinal product that results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, or results in congenital anomaly/birth defect.
Measured: Approximately 170 days.
The severity of serious adverse events (SAEs)
A serious adverse event (SAE) is defined as an AE occurring during any study phase and at any dose of medicinal product that results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, or results in congenital anomaly/birth defect.
Measured: Approximately 170 days.
Assessment of pulmonary function test results-forced vital capacity (FVC)
Pulmonary function test is a test to explore the functional status of human respiratory system with the knowledge of exercise respiratory physiology and modern examination technology. Forced vital capacity (FVC) (mL) will be measured at Visits 1, 8, 14 and 16, to assess the changes in FVC from baseline to post-dose.
Measured: Approximately 170 days.
Assessment of pulmonary function test results-forced vital capacity percent predicted (FVCpp)
Pulmonary function test is a test to explore the functional status of human respiratory system with the knowledge of exercise respiratory physiology and modern examination technology. Forced vital capacity percent predicted (FVCpp) (%) will be measured at Visits 1, 8, 14 and 16, to assess the changes in FVCpp from baseline to post-dose.
Measured: Approximately 170 days.
Assessment of pulmonary function test results-forced expiratory volume in 1 second (FEV1)
Pulmonary function test is a test to explore the functional status of human respiratory system with the knowledge of exercise respiratory physiology and modern examination technology. Forced expiratory volume in 1 second (FEV1) (L) will be measured at Visits 1, 8, 14 and 16, to assess the changes in FEV1 from baseline to post-dose.
Measured: Approximately 170 days.
Assessment of pulmonary function test results-diffusing capacity of the lungs for carbon monoxide (DLCO)

Secondary outcomes (11)

Evaluate the area under the serum drug concentration-time curve from time zero to the last quantifiable time point (AUC0-t) of PMG1015.
AUC is a pharmacokinetic parameter that represents the concentration of a drug in the blood at a certain time.
Measured: Approximately 170 days.
Evaluate the area under the serum drug concentration-time curve from time zero to infinity (AUC0-∞) of PMG1015.

Measured: Approximately 170 days.
Evaluate the maximum concentration (Cmax) of PMG1015.
Cmax refers to the highest concentration of a drug in the blood after administration, which is related to the dose, route of administration, dosing frequency, and time to reach the peak concentration.
Measured: Approximately 170 days.
Evaluate the time to reach the maximum concentration (Tmax) of PMG1015.
Tmax refers to the time when a drug reaches its maximum concentration and exhibits its maximum effect in the body.
Measured: Approximately 170 days.
Evaluate the half-life (t1/2) of PMG1015.
t1/2 refers to the time required for the drug concentration in the blood to decrease by half.
Measured: Approximately 170 days.
Evaluate the clearance rate (CL) of PMG1015.
CL is the volume of blood that is completely cleared of a drug per unit time by the excretory organs, and its unit is usually mL·(min·kg)-1 or L·(h·kg)-1.
Measured: Approximately 170 days.
Evaluate the distribution volume (Vz) of PMG1015.
Vz is a pharmacokinetic parameter that reflects the extent of drug distribution in various tissues in the body.
Measured: Approximately 170 days.
Evaluate the elimination rate constant (λz) of PMG1015.
λz is referred to as the elimination rate constant, which is defined as the ratio of the amount of compound eliminated per unit time to the total amount, with its unit being the reciprocal of time.
Measured: Approximately 170 days.
Correlation between the dose and exposure.
Dose refers to the quantity of drug administered at one time to achieve the desired therapeutic effect, and it can vary depending on the patient's needs and medical condition.
Measured: Approximately 170 days.
Incidence of PMG1015-induced and PMG1015-boosted ADAs.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PMG1015 in people with IPF, run by Pulmongene Ltd. at 7 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 4 inclusion and 10 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: finished, as of the sponsor's last update on 25 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The incidence of treatment-emergent adverse events (TEAEs) (time frame: Approximately 170 days.). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05895565.

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 25 Nov 2025; AzTrials last refreshed its copy on 7 Nov 2026.
