Experimental pill avenciguat targets liver blood pressure in cirrhosis – but trial halted early
NCT ID NCT05161481
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a drug called Avenciguat in adults with liver cirrhosis and high blood pressure in the portal vein (the main vessel to the liver). Participants took either a low or high dose of Avenciguat or a placebo twice daily for 24 weeks. The goal was to see if the drug could lower this blood pressure. The trial was terminated early, so results are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Avenciguat (BI 685509)
- What this could lead to
- If it works, this could point toward a new oral treatment to lower dangerous blood pressure in the liver's main vein for people with cirrhosis.
- What could go wrong
- This was a small, early-phase (phase 2) trial that was terminated, so results are limited. It is not yet proven to be safe or effective, and side effects are possible.

Inclusion Criteria: 1. Signed and dated written informed consent in accordance with International Council on Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial 2. Male or female who is ≥ 18 (or who is of legal age in countries where that is greater than 18) and ≤ 75 years old at screening 3. Clinical signs of Clinically Significant Portal Hypertension (CSPH) as described by either one of the points below. Each trial patient must have a gastroscopy during the screening period or within 6 months prior to screening. * documented endoscopic proof of oesophageal varices and / or gastric varices at screening or within 6 months prior to screening * documented endoscopic-treated oesophageal varices as preventative treatment 4. CSPH defined as baseline Hepatic Venous Pressure Gradient (HVPG) ≥ 10 mmHg, based on a local interpretation of the pressure tracing 5. Diagnosis of compensated alcohol-related cirrhosis. Diagnosis must be based on histology (historical data is acceptable) or on clinical evidence of cirrhosis (e.g. platelet count \< 150 x 10\^9/L \[150 x 10\^3/µL\], nodular liver surface on imaging or splenomegaly) 6. Abstinence from significant alcohol misuse / abuse for a minimum of 2 months prior to screening, and the ability to abstain from alcohol throughout the trial (both evaluated based on Investigator judgement) 7. Willing and able to undergo HVPG measurements per protocol (based on Investigator judgement) 8. If receiving statins must be on a stable dose for at least 3 months prior to screening, with no planned dose change throughout the trial Further inclusion criteria apply. Exclusion Criteria: 1. Previous clinically significant decompensation events (e.g. ascites \[more than perihepatic ascites\], Variceal Haemorrhage (VH) and / or apparent Hepatic Encephalopathy (HE)) 2. History of other forms of chronic liver disease (e.g. non-alcoholic steatohepatitis (NASH), Hepatitis B virus (HBV), untreated Hepatitis C Virus (HCV), autoimmune liver disease, primary biliary cholangitis, primary sclerosing cholangitis, Wilson's disease, haemachromatosis, alpha-1 antitrypsin (A1At) deficiency) 3. Has received curative anti-viral therapy with direct-acting anti-virals within the last 2 years for HCV, or, if such treatment was \> 2 years ago and there is no sustained virological response (SVR) at screening, or, must take curative anti-viral therapy with direct-acting anti-virals throughout the trial 4. Alcohol-Related Liver Disease (ARLD) without adequate treatment (e.g. lifestyle modification) or with ongoing pathological drinking behaviour (misuse / abuse based on Investigator judgement) 5. Must take, or wishes to continue the intake of, restricted concomitant therapy or any concomitant therapy considered likely (based on Investigator judgement) to interfere with the safe conduct of the trial 6. Systolic Blood Pressure (SBP) \< 100 mmHg and Diastolic Blood Pressure (DBP) \< 70 mmHg at screening 7. Model of End-stage Liver Disease (MELD) score of \> 15 at screening, calculated by the central laboratory 8. Hepatic impairment defined as a Child-Turcotte-Pugh score ≥ B8 at screening, calculated by the site, using central laboratory results Further exclusion criteria apply.
