Gut Microbiota in Liver Cancer (Treated With TKIs In Combination With ICIs)

Официальное название

A Randomized Controlled Trial Evaluating the Effects of Oral Enterobacterial Capsules in Liver Cancer Patients Treated With Tyrosine Kinase Inhibitors (TKIs) in Combination With Immune Checkpoint Inhibitors (ICIs)

Обзор

To evaluate the additional efficacy and safety of oral enterobacterial capsules in patients with intermediate and advanced liver cancer and treated with tyrosine kinase inhibitors (TKIs) combined with immunotherapy.

Подробное описание

This is a prospective, single-center, randomized, double-blind controlled trial. The clinical study is divided into 2 groups:

Group 1) Patients in the control group were given lenvatinib 8mg (≤ 60 kg body weight) or 12 mg (\> 60 kg body weight) orally once a day, combined with PD-1 monoclonal antibody 200mg intravenously once every 3 weeks until disease progression, intolerable toxicity or death, and patients in the control group were given intestinal bacteria capsules placebo.

Group 2) Patients in the study group were given lenvatinib 8 mg (≤ 60 kg body weight) or 12 mg (\> 60 kg body weight) orally once a day in combination with PD-1 monoclonal antibody 200 mg intravenously every 3 weeks until disease progression, intolerable toxicity, or death, and patients in this study group were given intestinal bacteria capsules.

Oral administration of intestinal bacteria capsules 6 capsules/day, after observing no adverse reactions, oral administration for 10 consecutive days, 6 capsules/day from the second day to the tenth day, and then discontinued to the next course of treatment.

Total course of treatment: a total of 4 courses of oral intestinal bacteria capsules, each course of oral administration for 10 days, and a course of 21 days; A course of TKI combined with immune checkpoint inhibitors treatment is 21 days until the disease progresses or intolerable toxicity and side effects appear.

Observe the metrics: Primary Clinical Endpoint - Progression-Free Survival (PFS); Secondary Clinical Endpoints - Overall Growth Phase (OS), Objective Response Rate (ORR), Duration of Response (DOR), and Disease Control Rate (DCR). The new RECIST1.1 criteria were used for the efficacy evaluation system, the CTCAE5.0 grading system was used for the evaluation of common adverse reactions during treatment, and other indicators included imaging including conventional biochemical indexes such as CT and ultrasound, as well as quality of life scores.
