Evaluation of Postoperative Ascites After Somatostatin Infusion Following Hepatectomy for Hepatocellular Carcinoma (SOMAPROTECT01)

September 30, 2025 updated by: Hospices Civils de Lyon

Evaluation of Postoperative Ascites After Somatostatin Infusion Following Hepatectomy for Hepatocellular Carcinoma: Multicenter Randomized Double-blind Placebo Controlled Trial (SOMAPROTECT01)

Most patients undergoing hepatectomy for hepatocellular carcinoma (HCC) suffer from underlying liver disease and are exposed to the risk of postoperative ascites, with subsequent morbidity, liver and renal failure, the need for specific treatments and prolonged hospital stay. Postoperative ascites is favored by an imbalance between portal venous inflow and the diminished hepatic venous outflow. Finding a reversible, non-invasive method for modulating the portal inflow would be of interest: it could be used temporarily during the early postoperative course to prevent acute portal hypertension. Somatostatin, a well-known drug already used in several indications, may limit the risk of postoperative ascites and liver failure by decreasing portal pressure after hepatectomy for HCC in patients with underlying liver disease.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
179

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients with HCC diagnosed by histology or by imaging findings according to the Barcelona Clinic Liver Cancer Group
  • Patients with a single or multiple HCCs deemed to be resectable with a curative intent at the preoperative evaluation
  • Patients for whom an indication for hepatectomy has been decided and approved by multidisciplinary board:
  • by laparotomy
  • by coelioscopy with resection of at least 2 liver segments
  • Patients with any underlying liver disease with or without proven cirrhosis, regarding histological features (including F2-F3-F4 fibrosis with or without cirrhosis) or with other evidence of a diseased liver if no biopsy has been performed preoperatively (dysmorphic liver or evidence of portal hypertension at imaging findings, oesophageal varices at endoscopy)
  • Age ≥ 18 years
  • Patients with ability to understand and sign a written inform consent form
  • Patients who will be available for follow-up

Exclusion Criteria:

  • Patients participating in another interventional research in progress or including an exclusion period still in progress at pre-inclusion (except interventional research with minimal risks and constraints that do not interfere with the judgement criteria of the study according to the judgement of the coordinating investigator).
  • Patients with evidence of a healthy liver at biopsy

Disease-associated non-inclusion criteria include:

  • Another histologic type of hepatic tumor besides HCC
  • Distant extra-hepatic metastases, including peritoneal carcinomatosis
  • The existence of complete portal thrombosis of the main portal trunk

Operative technique-associated non-inclusion criteria include:

- Indication of coelioscopy with resection of less than 2 liver segments
