AZD4831 for NASH with Fibrosis (COSMOS Trial)

Phase 2
Waitlist Available
Research Sponsored by AstraZeneca
Eligibility Criteria Checklist

Must have
Be older than 18 years old
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 12 weeks

Summary

This trial is testing a new drug called AZD4831 to see if it can help people with a liver condition known as NASH, which causes liver damage and scarring. The study involves adults who have been diagnosed with NASH but do not have cirrhosis. Researchers hope that AZD4831 will reduce liver inflammation and scarring.

Who is the study for?
Adults aged 18-75 with Non-alcoholic Steatohepatitis (NASH) and liver fibrosis, confirmed by biopsy, can join this trial. They should have a history of increased liver enzymes but no other liver diseases or recent use of weight loss drugs or treatments that could affect the fatty liver.
What is being tested?
The study is testing AZD4831 against a placebo to see its effects on NASH with fibrosis. Participants will be randomly assigned to either the drug or placebo for 12 weeks and monitored for an additional 4 weeks after treatment ends.
What are the potential side effects?
Specific side effects are not listed, but participants may experience unexpected reactions due to the experimental nature of AZD4831. The safety follow-up period helps identify any potential adverse events from the treatment.

Other Research
Common treatments for Non-alcoholic Fatty Liver Disease (NAFLD) target reducing liver inflammation and fibrosis, which are critical in preventing disease progression. For instance, pioglitazone, a PPAR-gamma agonist, improves insulin sensitivity and reduces liver fat. Obeticholic acid, a farnesoid X receptor agonist, decreases liver inflammation and fibrosis by modulating bile acid pathways. Additionally, GLP-1 receptor agonists like liraglutide enhance insulin secretion and reduce hepatic fat content. These treatments are crucial for NAFLD patients as they address the underlying mechanisms of liver damage, potentially halting or reversing disease progression.
