About this study
Official title: A Phase I, Randomized, Double-blind, Placebo-controlled, Single-dose, Dose-escalation Clinical Study to Evaluate the Safety, Tolerability and Pharmacokinetic Profiles of AK0406 in Healthy Adult Participants
This study is a phase I, single-center, randomized, double-blind, placebo-controlled study of AK0406 as a first-in-human (FIH) trial to evaluate the safety, tolerability and pharmacokinetics (PK) of AK0406 in healthy adult participants.
Read the detailed description
This study consists of four cohorts: Cohort A: 150 milligram (mg) subcutaneous injection (s.c.) Cohort B: 300 mg s.c. Cohort C: 600 mg s.c. Cohort D: 900 mg s.c. Each cohort will enroll 8 healthy adult participants (AK0406: placebo = 3: 1), including both females and males. Dose escalation will follow a sequential order, beginning with the lowest dose 150 mg and proceeding to 300 mg, 600 mg, and finally 900 mg. A sentinel-dosing strategy will be implemented. For the first cohort (Cohort A) and the last cohort (Cohort D): the first two participants (1 AK0406, 1 placebo) will be dosed and observed for at least 7 days. The first two participants (1 AK0406, 1 placebo) in Cohort B and Cohort C will be dosed and observed for over 48 hours. After both the investigator and sponsor agree with the acceptable safety and tolerability profile, the remaining 6 participants (5 AK0406, 1 placebo) in that cohort will be dosed.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AK0406 150 mg, AK0406 300 mg and AK0406 600 mg in people with Healthy Participants, run by Shanghai Ark Biopharmaceutical Co., Ltd. at 1 site in Australia.
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 11 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: under way, not looking for participants, as of the sponsor's last update on 29 Oct 2026. 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 Australia. 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?
This study is still under way. Results are not available in the source record yet.
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?
Adverse events (time frame: Up to Day 181). 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 29 Oct 2026.
