NCT ID: NCT05189834

Last Updated: 2024-02-28

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: NA
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-03-11
• Study Completion Date: 2022-07-30

Brief Summary

Randomized crossover pilot clinical trial in which 10 cirrhotic patients with covert hepatic encephalopathy (CHE) will be assigned to take GELSECTAN® (TID) or placebo for 30 days. After a washout period of 15 days, the treatment branches will be interchanged.

The objective of the trial is to obtain pilot variances to design a phase II trial, in which the efficacy of the treatment will be tested. As an exploratory objective, the efficacy of the product in the treatment of covert hepatic encephalopathy will be analyzed.

Main endpoint Improvement in CHE after 30 days of treatment with GELSECTAN®, measured by the Psychometric hepatic encephalopathy score (PHES)

5. MELD score greater than 25 at the time of inclusion.

6. Hospitalization for any reason.

7. Neurological or psychiatric comorbidity that makes the evaluation of hepatic encephalopathy difficult. This includes patients with mental illnesses (dementia, cerebrovascular disease with sequelae, Parkinson's disease, schizophrenia).

8. Active digestive bleeding. Before inclusion, there must have been a 48-hour period without signs of bleeding.

9. Patients with hypersensitivity or allergy to any of the components of GELSECTAN® (grape, pea).

10. Clinical situations in which the administration of oral feeding is contraindicated.

11. Active oncological processes, including hepatocarcinoma.

12. Active infection of any origin.

13. Acute renal failure (AKI). Defined by the current diagnostic criteria of the KDIGO group (Kidney Disease Improving Global Outcomes).

14. Dehydration Diagnosed by physical examination of the patient.
