Trial summary

Interleukin (IL)-6 is a cytokine produced in response to infection and tissue damage. IL-6 is believed to act as a key mediator in chronic inflammation and autoimmune diseases such as inflammatory bowel diseases. IL-6 is known to be involved in at least two distinct signalling pathways, classical and trans-signalling. Read more about this study

About this study

Official title: A Placebo-controlled, Within-group Randomised, and Double-blind Trial Investigating Safety, Tolerability, and Pharmacokinetics of FE 999301 After Single Ascending Doses in Healthy Japanese Men

Interleukin (IL)-6 is a cytokine produced in response to infection and tissue damage. IL-6 is believed to act as a key mediator in chronic inflammation and autoimmune diseases such as inflammatory bowel diseases. IL-6 is known to be involved in at least two distinct signalling pathways, classical and trans-signalling. The hypothesis is that classical signalling by IL-6 infers some beneficial effects (e.g. on gut barrier function), while excessive IL-6 trans-signalling may have detrimental effects. Olamkicept (FE 999301) has been shown in vitro to be a selective IL-6 trans-signalling inhibitor and administered at lower doses, it has proven to induce clinical improvement for patients with ulcerative colitis. The aim of this trial is to investigate safety, tolerability, immunogenicity and pharmacokinetics of Olamkicept at higher doses, to support the clinical development program. The hypothesis for this study is that treatment with higher doses of Olamkicept will result in greater clinical improvement for participants with inflammatory bowel diseases.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing FE 999301 in people with Gastroenterology, run by Ferring Pharmaceuticals at 1 site in Japan.

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 6 inclusion and 16 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 6 Dec 2024. 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 Japan. 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 treatment-emergent adverse events (time frame: From baseline up to 36 days after a single dose infusion). The study lists 24 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 NCT06515834, which also lists 1 linked publication.

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 6 Dec 2024.
