About this study

Official title: A Phase 1/1B Study to Assess Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Nebulized CMR316 in Healthy Volunteers and Patients With Idiopathic Pulmonary Fibrosis

The purpose of this study is to assess the safety, tolerability and pharmacokinetics single and multiple inhaled doses of CMR316 in healthy volunteers and patients with Idiopathic Pulmonary Fibrosis (IPF).

Read the detailed description

This is a 3-part, single-center study; Part 1 will evaluate single ascending doses (SAD) and Part 2 will evaluate multiple ascending doses (MAD; once weekly dosing for 4 weeks) of nebulized CMR316 or placebo in healthy male and female subjects. Part 3 will assess multiple doses (once weekly dosing for 5 weeks) of nebulized CMR316 (open-label) in subjects with IPF.

  5. Number of participants with clinically significant abnormal laboratory test results

    Results outside of laboratory defined normal ranges will be analyzed for clinical significance and used to determine safety and tolerability of CMR316

    Measured: Part 1: Day 1 through Day 15; Part 2: Day 1 through Day 36; Part 3: Day 1 through Day 50

Secondary outcomes (3)
  1. Assess pharmacokinetics, AUC, as available

Model description
Part 1 Cohorts 1-4: double-blind, assess single ascending doses (SAD) of nebulized CMR316. Cohort 5: open label, single dose (at a dose previously determined to be safe) \& incl. lung sample collection via bronchoscopy for PK \& PD. Part 2: double blind, assess multiple ascending dose (MAD) cohorts of CMR316 administered once weekly for 4 weeks. If further PK/PD data from lung samples is required to determine appropriate RP2D then a sub-group of open-label participants who will undergo bronchoscopies may be enrolled to any or all MAD cohorts. Parts 1 \&2 are not required to be conducted entirely sequentially if justified by PK \& safety obtained. The first MAD cohort will not start until data are available from SAD Cohort 3 \& dosing for each MAD cohort will not exceed a dose level previously deemed safe in a SAD cohort. Part 3: IPF patients, will not start until data are available and reviewed from Parts 1 \& 2 and will not exceed a dose level previously deemed safe in a SAD/MAD cohort.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CMR316 in people with Pulmonary Fibroses, Idiopathic, run by Calibr, a division of Scripps Research at 1 site in Germany.

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 14 inclusion and 40 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 9 Jul 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 Germany. 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?

Number of participants with adverse events (time frame: Part 1: Day 1 through Day 15; Part 2: Day 1 through Day 36; Part 3: Day 1 through Day 50). The study lists 5 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 9 Jul 2026.
