About this study
Official title: Phase 1a Randomized, Double-Blind, Placebo-Controlled, Single Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamic Effects of AKB 4924 in Healthy Male Volunteers
This will be a double-blind, randomized, placebo-controlled, single ascending dose, Phase I study in healthy male subjects.
Read the detailed description
Single oral doses of AKB-4924 will be investigated in up to 6 sequential cohorts of 8 healthy male subjects. Primarily 6 dose levels are planned; the proposed doses are 20 mg, 60 mg, 120 mg, 240 mg, 360 mg, and 480 mg. Actual doses may be decreased or increased based on the safety and tolerability of the drug, as determined by the Investigator and Sponsor. Additional cohorts may be added as needed to test lower, higher, or repeat doses.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AKB-4924 in people with IBD, run by Aerpio Therapeutics at 1 site in Canada.
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 3 inclusion and 23 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 16 Mar 2017. 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 Canada. 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?
Single ascending dose (SAD): Safety and tolerability of AKB-4924 (time frame: 8 days after a single oral dose). 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 16 Mar 2017; AzTrials last refreshed its copy on 6 Nov 2026.
