ECC4703 with Sulfasalazine and Pitavastatin in adults with NAFLD and dyslipidemia

Official title: A Phase 1, Open-Label, Fixed-Sequence, Single-Center, Two-Period, Drug-Drug Interaction Trial in Healthy Adult Participants to Evaluate the Effect of Steady-State ECC4703 on the Pharmacokinetics of Sulfasalazine (BCRP Probe Substrate) and Pitavastatin (OATP1B1/OATP1B3 Probe Substrate)

Run by Eccogene · NCT07726368 · Data updated 2026-11-12

This early study tests whether adding ECC4703 to sulfasalazine and pitavastatin is safe and how the body handles the combination in adults with fatty liver disease and high cholesterol.

Is this trial a fit for you?

Likely a good fit

Adults 18–65 without significant health issues that could confound safety or pharmacokinetic results, and who can tolerate withholding other medications around the dosing period.

Probably not a fit

Individuals with significant renal, hepatic, cardiovascular, psychiatric, or other conditions posing safety risks may not benefit and could be excluded.

What this trial studies

This is a Phase 1 interventional study examining the safety, tolerability, and pharmacokinetics of ECC4703 when given together with sulfasalazine and pitavastatin. The trial enrolls adults aged 18 to 65 who are generally healthy aside from potential NAFLD/dyslipidemia risk factors as determined by investigators. Participants will undergo clinical assessments, monitoring, and laboratory tests to characterize potential drug interactions and safety signals. The study is led by Eccogene with Nucleus Network as the site in Melbourne, Australia. Primary outcomes focus on safety and how the combination is processed in the body; exploratory aims may inform future dosing and development.

Why it matters

Potential benefit: If successful, the combination could support safer and more effective use of ECC4703 with standard therapies for NAFLD and dyslipidemia.

How similar studies have gone: As a first-in-class safety/pharmacokinetic exploration, prior data on the exact combination is limited; outcomes will inform feasibility for later studies.

Inclusion Criteria:

* Male or female between the ages of 18 and 65 years, inclusive, at the time of Screening.
* Are healthy and in the opinion of the Investigator have an acceptable medical history (free from significant cardiac, pulmonary, gastrointestinal, hepatic, renal, haematological, neurological, infective, or psychiatric diseases as determined by medical history over the past 5 years, physical examination, vital signs, 12-lead ECG, and clinical laboratory tests).
* Has not consumed and agrees to abstain from taking any prescription drugs or non-prescription drugs for 7 days or 5 half-lives (whichever is longer) prior to first dose of trial treatment and continuing through end of the Treatment Period.

Exclusion Criteria:

* Has a history of significant renal, hepatic, cardiovascular, psychiatric, neoplastic, thyroid disease/abnormality or other disease which, in the opinion of the Investigator, represents a safety risk for taking part in the trial.
* Has a history of sensitivity to any of the trial treatments (and/or their excipients), or severe drug or other allergy
* Has a history of drug abuse within the previous 2 years, or a positive drug screen at Screening and/or Day -1.
* Regular consumption of more than 10 standard alcoholic drinks/week and/or more than 4 standard alcoholic drinks on any one day
* Has a history or current diagnosis of a significant psychiatric disorder that would, in the opinion of the Investigator, affect the participant's ability to comply with the trial requirements.
* Has a personal or family history of hereditary muscular disorders, previous statin-induced myopathy/rhabdomyolysis, or unexplained repeated or severe muscle pain.
* Has a history of any unexplained chronic skin rash or autoimmune skin diseases.
* Has a personal or family history of Stevens-Johnson syndrome (SJS), or other severe drug-induced skin reactions.
