  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Subjects must provide written informed consent prior to any Screening procedures being performed.
  • Male and female subjects 18-55 years of age (inclusive) on the day of signing the informed consent.
  • Subjects deemed in good physical health by the Investigator, as determined by no clinically significant findings from medical history, laboratory safety tests (serology, hematology, biochemistry and urinalysis), physical examination, vital signs, and electrocardiogram (ECG).
  • Women of child-bearing potential (WOCP) must agree not to attempt to become pregnant or donate ova, and to use a highly effective form of hormonal or non-hormonal birth control during the study and for 180 days after the last study drug administration, including:
  • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation:

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GB1211 in people with Pharmacokinetics, run by Galecto Biotech AB 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 25 inclusion and 25 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 Sep 2023. 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. 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?

To measure the maximum plasma concentration of GB1211 (Cmax) (time frame: 5 weeks). 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?

On the ClinicalTrials.gov record for NCT05747573, 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 1 Sep 2023; AzTrials last refreshed its copy on 6 Nov 2026.
