About this study
Official title: Safety, Tolerability, and Pharmacokinetic Study of Single Ascending Dose of GV101 in Healthy Subjects.
This is a single center Phase 1, placebo-controlled, randomized, double blind, first-in-human (FIH), sequential single ascending dose (SAD) study.
Read the detailed description
GBS-101 is a single center Phase 1, placebo-controlled, randomized, double blind, first-in-human (FIH), sequential single ascending dose (SAD) study to evaluate the safety, tolerability and PK of GV101 in healthy subjects. 8 healthy subjects wills be enrolled cohorts 5 - 7 cohorts of the study. Cohorts 1-4 were previously completed with a tablet form of the study drug at 50 mg, 100 mg, 200 mg, and 400 mg. Planned cohorts 5 - 7 will be dosed 400 mg (liquid), 800 mg (liquid), 1600 mg (liquid) or matched placebo.. Participants will be randomized in a 3:1 ratio, 1:1 for 2 sentinel subjects and 5: 1 GV101 drug to matching placebo thereafter. Subjects in each cohort will receive a single oral dose of GV101 or matching placebo under fasting conditions. A staggered schedule will be used for each dose level, where 2 sentinel subjects (1 active and 1 placebo) will be dosed first, with the remaining 6 subjects (5 active and 1 placebo) dosed at least 24 hours after the sentinel subjects.
This study of GV101 will provide safety, tolerability, and plasma pharmacokinetic data in healthy individuals. The PK component will characterize the PK of GV101 to inform dosing and may help to correlate exposures treatment-related AEs.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GV101 in people with Phase 1, run by Graviton Bioscience Corporation at 1 site in United States.
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 15 inclusion and 21 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 17 Oct 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 United States. 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?
Treatment emergent AEs (time frame: Up to day 7.). 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 17 Oct 2023; AzTrials last refreshed its copy on 7 Nov 2026.
