Brief Summary

Brief summaries of CZXH-PH-ALV-2403 The goal of this clinical trial is to learn if the combination of alverine and carvedilol works to treat portal hypertension in adult patients with liver cirrhosis. It will also learn about the safety of alverine.

The main question it aims to answer is:

For patients with liver cirrhosis and portal hypertension who have been treated with carvedilol at a dose of up to 15 mg/day or at a lower dose that is the maximum tolerated for at least 3 months, and still have a hepatic venous pressure gradient (HVPG) of 12 mmHg or higher and up to and including 20 mmHg, can the addition of alverine help to reduce portal hypertension? On the basis of maintaining unchanged routine hepatoprotective and symptomatic supportive treatments and the original dose of carvedilol, participants will be administered with compound alverine citrate capsules (Le Jian Su; specification: each capsule contains alverine citrate 60 mg and simeticone 300 mg; manufactured by Laboratoires MAYOLY SPINDLER), at a dosage of 180 mg/day (1 capsule orally, 3 times a day), for a continuous period of 24 weeks.

Detailed Description

1. Study Overall Design This trial is a prospective, single-arm, multicenter, exploratory clinical trial. Subjects who meet the inclusion criteria and do not meet the exclusion criteria enter a 24-week treatment period after signing the informed consent form. In addition to the baseline period, subjects undergo efficacy assessment 24 weeks after treatment. The safety of carvedilol combined with alverine treatment for portal hypertension in patients with liver cirrhosis is evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0; safety is assessed through laboratory tests, 12-lead electrocardiograms, and vital signs, physical examinations, etc.

2. Study Purpose 2.1 Primary Study Purpose To evaluate the efficacy of carvedilol combined with compound alverine citrate capsules in the treatment of portal hypertension in patients with liver cirrhosis.

2.2 Secondary Study Purposes 2.2.1 To evaluate the effect of carvedilol combined with compound alverine citrate capsules on the incidence of esophageal and gastric variceal bleeding and other decompensating events in cirrhosis; 2.2.2 To evaluate the safety of carvedilol combined with compound alverine citrate capsules in the treatment of portal hypertension in patients with liver cirrhosis.

3. Study Endpoints 3.1 Primary Endpoint The proportion of patients who achieve a reduction in HVPG of ≥10% from baseline or a reduction to below 12mmHg after 24 weeks of treatment (the treatment response rate).

3.2 Secondary Endpoints 3.2.1 The reduction in HVPG from baseline levels after 24 weeks of treatment; 3.2.2 The incidence of decompensating events in cirrhosis during the treatment period (esophageal and gastric variceal bleeding and rebleeding, new-onset ascites/progression of ascites, spontaneous bacterial peritonitis, overt hepatic encephalopathy, acute kidney injury/hepatorenal syndrome, etc.); 3.2.3 The treatment response rate at 12 weeks; 3.2.4 The reduction in HVPG from baseline HVPG after 12 weeks of treatment; 3.2.5 The reduction in mean arterial pressure of subjects after treatment compared to baseline values; 3.2.6 The reduction in heart rate of subjects after treatment compared to baseline values; 3.2.7 The incidence of adverse events, serious adverse events, and adverse events leading to treatment discontinuation after treatment (evaluated according to CTCAE version 5.0).
