Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 78 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2016-11-28

Brief Summary

The propose of this study is evaluate the safety and efficacy of MG4101 (allogeneic Natural killer cells) in patients with hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE).

Detailed Description

This is randomized, multi-center, open-labeled, Phase 2a study in patients with HCC after transarterial chemoembolization (TACE). A total of 78 patients will be randomized(1:1) into one of the two group, to receive adjuvant therapy using MG4101 (allogeneic Natural killer cells, Treatment group) or no adjuvant therapy (Control group).

Patients who were assigned Treatment group will receive 2 cycles of MG4101 (each cycle is 3 treatments at a frequency of once per week, between each cycle has 3 weeks of withdrawal period). After treatment period, patients will undergo follow up for progression and survival every 12 weeks (± 7 days) and follow up 1 year after the last patient's enrollment date.

The Control group's patients will will undergo follow up for progression and survival every 12 weeks (± 7 days) and follow up 1 year after the last patient's enrollment date.

Conditions

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

The Control Group

Patients will be randomized 1:1 to the control group and the treatment group. Patients who had allocated control group will not receive adjuvant treatment.

Group Type: NO_INTERVENTION

No interventions assigned to this group

The Treatment Group (MG4101)

Patients will be randomized 1:1 to the control group and the treatment group. The treatment group will receive 6 times of MG4101(allogeneic natural killer cells) on week 0, 1, 2, 5, 6, 7.

Group Type: EXPERIMENTAL

MG4101

Intervention Type: BIOLOGICAL

MG4101 is ex vivo-expanded, allogeneic natural killer cells. MG4101 were manufactured from normal healthy donor who underwent lymphopheresis under good manufacturing practice (GMP) conditions.
