Measured: From baseline to follow-up visit (on Day 14 in Cohort 1, or On Day 24 in Cohort 2)
Change from Baseline in blood pressure, measured using a sphygmomanometer via a cuff on the arm
Measured: From baseline to follow-up visit (on Day 14 in Cohort 1, or On Day 24 in Cohort 2)
Change from Baseline in heart rate, measured in beats-per-minute by a vital signs machine
Measured: From baseline to follow-up visit (on Day 14 in Cohort 1, or On Day 24 in Cohort 2)
Change from Baseline in respiratory rate, measured in breaths-per-minute manually via a 60-second count

Changes from Baseline in Clinical Laboratory Parameters in haematology.
Blood samples will be collected. All haematology assessments will be assessed by a certified local laboratory, using that laboratory's normal ranges. Any clinically significant changes will be recorded as Adverse Event (AE). The severity of each AE (and SAE or Serious Adverse Event) will be graded using a 5-point scale

Changes from Baseline in Clinical Laboratory Parameters in blood chemistry.
Blood samples will be collected. All blood chemistry assessments will be assessed by a certified local laboratory, using that laboratory's normal ranges. Any clinically significant changes will be recorded as Adverse Event (AE). The severity of each AE (and SAE or Serious Adverse Event) will be graded using a 5-point scale
Measured: From baseline to follow-up visit (on Day 14 in Cohort 1, or On Day 24 in Cohort 2)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ECC0509, Metformin and Caffeine in people with Steatohepatitis, Nonalcoholic and Osteo Arthritis, run by Eccogene 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 3 inclusion and 10 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: opening soon, as of the sponsor's last update on 14 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. 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?
Contact Eccogene Clinical Trials (86-21-61053022, contact@eccogene.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum plasma concentration of metformin in the blood of participants who have taken ECC0509 (as part of called pharmacokinetic or 'PK' testing) (time frame: Blood samples for PK testing of sulfasalazine will be collected on Days 1, 2, 6 and 7). The study lists 8 primary outcomes in all. 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 14 Oct 2026.
