Phycocyanin for liver protection in fibrosis and cirrhosis

Official title: Research on the Role of Phycocyanin in the Prevention, Treatment, and Mechanism of Liver Fibrosis/Cirrhosis

Run by Second Affiliated Hospital, Zhejiang University, School of Medicine · NCT07271576 · Data updated 2026-11-12

This trial will test whether a daily phycocyanin supplement can help adults with liver fibrosis or cirrhosis by lowering liver enzymes and improving liver stiffness.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with a clinical diagnosis of liver fibrosis or cirrhosis, who have been clinically stable for at least four weeks and can provide informed consent, are the intended participants.

Probably not a fit

People with severe comorbidities, known allergy to phycocyanin, recent acute worsening of illness, or who cannot comply with study procedures are unlikely to benefit from this trial.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants with liver fibrosis or cirrhosis will take one sachet of either phycocyanin or a placebo daily for at least four weeks and will be compared to a control group receiving maltodextrin placebo. The trial measures changes in blood markers of liver injury (like ALT and AST) and liver stiffness by ultrasound, with blood and stool samples collected before and after treatment. Routine clinic visits every 2–3 months will monitor safety with blood and urine tests. The design uses a placebo control to determine whether phycocyanin produces measurable improvements over no active supplement.

Why it matters

Potential benefit: If successful, phycocyanin could offer a low-risk supplement option that lowers liver enzyme levels and reduces liver stiffness, potentially slowing progression of liver fibrosis or cirrhosis.

How similar studies have gone: Preclinical studies and a few small clinical reports suggest antioxidant and liver-protective effects of phycocyanin, but robust randomized clinical evidence in fibrosis or cirrhosis is currently limited.
