What is being measured

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

  1. The maximum plasma concentration (Cmax)

    Measured: From Day 1 to Day 24.

  2. Area under the concentration curve from time 0 to extrapolated infinite time (AUC0-inf)

    Measured: From Day 1 to Day 24.

  3. Area under the concentration curve from time 0 to time of last quantifiable concentration (AUC0-tau)

    Measured: From Day 1 to Day 24.

  4. Area under the concentration curve from time 0 to time t (AUC0-t)

    Measured: From Day 1 to Day 24.

Secondary outcomes (4)
  1. Accumulative excretion rate (Ae)

    Measured: Day 1, Day 19 and Day 20.

  2. Fractional excretion (Fe)

    Measured: Day 1, Day 19 and Day 20.

  3. Renal clearance (CLr)

    Measured: Day 1, Day 19 and Day 20.

  4. Adverse events (AEs)

    Measured: From Day 1 to Day 30.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HRS-9813 Capsule, Nintedanib Soft Capsules and Pirfenidone Tablets in people with Pulmonary Fibrosis, run by Guangdong Hengrui Pharmaceutical Co., Ltd at 1 site 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 15 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 21 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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 maximum plasma concentration (Cmax) (time frame: From Day 1 to Day 24.). The study lists 4 primary outcomes in all. 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 21 Sep 2026.
