About this study

Official title: A Randomized Double-blind Placebo-controlled Phase I Study on the Safety, Tolerability and Pharmacokinetics/-Dynamics of Escalating Single Intravenous Doses of ADRECIZUMAB (HAM8101) in Healthy Male Subjects During Experimental Endotoxemia.

In this randomized, double-blind, placebo-controlled study, either a single dose of Adrecizumab (0.5, 2.0 or 8.0 mg/kg) or placebo will be administrated to 24 healthy male volunteers during experimental endotoxemia.

Read the detailed description

Adrenomedullin (ADM) is a natural occurring 52 amino acid peptide which is mainly expressed in endothelial and smooth muscle cells. ADM plasma levels are increased in patients with sepsis and related with severity of disease. ADM is a key regulator of vasotonus and of endothelial integrity in sepsis. Adrecizumab is an antibody against the N-terminus of ADM which only partially inhibits the bioactivity of ADM. Several septic animal studies have shown that administration of Adrecizumab leads to stabilization of hemodynamics in mice and pigs, improved renal function, reduced catecholamine demand, improved fluid balance and improved survival. The administration of Adrecizumab to rodents, non-human primates and recently humans, has been tolerated very well.

The experimental human endotoxemia model, in which healthy male volunteers receive a low dose of lipopolysaccharide (LPS) derived from Escherichia coli, is widely used to study the effects of systemic inflammation in humans in vivo and is considered a safe and highly reproducible method to activate the innate immune system. Furthermore, previous data has shown that experimental human endotoxemia results in increased plasma ADM levels. In this study, the investigators wish to assess the safety, tolerability and pharmacokinetics/-dynamics of Adrecizumab under inflammatory conditions in healthy volunteers.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EndotoxinDrug

    Also called LPS, Lipopolysaccharide

    At T=0 1 ng/kg E. Coli type O113 lipopolysaccharide is administrated intravenously as a bolus, followed by 1 ng/kg/hour for 3 hours.

  • PlaceboDrug

    At T=1 hour, placebo will be administered intravenously over a 1 hour period. Placebo is indistinguishable from Adrecizumab.

  • AdrecizumabDrug

    At T=1 hour, Adrecizumab will be administered intravenously over a 1 hour period.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Endotoxin and Adrecizumab in people with Healthy Volunteers, run by Adrenomed AG at 1 site in Netherlands.

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 20 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 Feb 2021. 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 Netherlands. 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?

Safety and tolerability expressed in total number of treatment related (serious) adverse events. (time frame: 3 months follow-up period). 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 Feb 2021.
