February 4, 2022 updated by: Prof. Shichun Lu, Chinese PLA General Hospital

A Multicenter, Randomized, Open-label Phase II Study of Expanded Activated Lymphocytes (EAL) as Adjuvant Therapy in Preventing Recurrence in Patients With Primary Hepatocellular Carcinoma (HCC) at High Recurrence Risk After Radical Resection

This is a multi-center, randomized, open-label pivotal phase II study to evaluate the efficacy and safety of EAL as adjuvant therapy in preventing recurrence in patients with primary HCC at high recurrence risk after radical resection.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

HCC, accounting for 80% of all liver cancers, is the third most common cause of cancer-related death worldwide. Radical resection is considered as a curative strategy for patients with primary HCC. However, over 50% of patients experience recurrence after resection, resulting in a very low 5-year survival rate. EAL are ex vivo expanded and activated lymphocytes comprising mainly CD8+ T cells derived from patients' peripheral blood. This is a multi-center, randomized, open-label pivotal phase II study to evaluate the efficacy and safety of EAL in preventing recurrence in patients with primary HCC at high recurrence risk after radical resection. Patients will be randomized in a 1:1 ratio to receive either 20 doses of EAL (1×10^9~2×10^10 per dose) infusion in combination of a single TACE or a single TACE only. Primary endpoint is the independent review committee-determined recurrence-free survival (from randomization to first recurrence or death from any cause). Secondary endpoints include overall survival, cancer-specific survival, adverse events and others.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
