About this study

Official title: Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Intravenous, Oral and Subcutaneous Doses of Inno8 in Healthy Male Participants

This study will test how different doses of study medicine (Inno8) work in the healthy men. The purpose of this study is to prove safety of Inno8 in healthy men, which will support further development of Inno8 in people with Haemophilia A. The study consists of three parts: single ascending dose (SAD), multiple ascending dose (MAD) and single subcutaneous dose (SSD). Each part will have more than one cohort (like sub-parts). No matter which part the participants will be enrolled in, they will either get the study medicine (Inno8) or a dummy medicine that looks like the study medicine but has no effect on the body (placebo). Which treatment participants get is decided by chance. The study medicine is a new medicine that cannot be prescribed by doctors. In the SAD and SSD part participants will receive a single injection of study medicine or placebo, and the study will last for up to 9 weeks. In the MAD part, participants will receive 1-2 tablets of study medicine or placebo daily for 10 days, and the study will last for up to 11 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing NNC0442-0344 A in people with Haemophilia A, run by Novo Nordisk A/S at 2 sites 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 5 inclusion and 6 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 1 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

SAD: Number of treatment emergent adverse events (time frame: From time of dosing (Day 1) to Day 36). The study lists 3 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 1 Apr 2026.
