Brief summary
This is an open-label, single arm, multicenter, Phase II clinical study to investigate the efficacy and safety profiles of autologous ATL administration in HCC patients after curative treatment. Among all the eligible patients, ratio of 7:2:1 for Stage I:II:IIIa of the HCC will be the enrolled strategy of the study to reflect the results of the previous study (Lee, Lee et al. 2015).
Detailed description
Eligible patients with HCC received curative treatment will be given ATL administration in this study. The investigational product ATL revealed great efficacy in previous clinical trials. This study aims to treat eligible patients, who had undergone curative treatment for HCC, with ATL as a preventive immunotherapy and to evaluate the effectiveness on the basis of patients' RFS rate in 12 months. The administration of the subject will be in a staggered manner for the first 3 patients. The 2nd and 3rd subject will not be dosed until the prior subject has taken the 4th dose of investigational products for at least 4 weeks. During the pretreatment period, peripheral blood for manufacturing the individualized ATL agent will be collected from patients at least 28 days before starting treatment. Patients will receive 200 mL of the ATL agent intravenously within 40 to 60 minutes without any premedication. They will be scheduled to receive the ATL 10 times at Weeks 1, 2, 3, 4, 6, 8, 10, 14, 18, and 22. A Data and Safety Monitoring Board (DSMB) will be appointed while 10% of schedule subjects were enrolled and complete 4 times of ATL infusions, the DSMB will convene a meeting to review safety data to date, including AEs and toxicities to indicate whether the study would advance unaltered, amend the protocol, or halt recruitment until a resolution of a specific issue.

Inclusion criteria
for Donor 1. Patients must be able to understand and sign the informed consent documents and aware of the investigational nature of the study. 2. Patient is ≥ 20 years old. 3. Patient has been diagnosed as HCC by pathological data or radiological test in the stage of I, II or IIIa according to the American Joint Committee on Cancer staging system (8th Edition). 4. Patient is scheduled to or has received tumor removal by curative treatments (e.g., surgical operation, percutaneous ethanol injection \[PEI\], microwave ablation \[MWA\], or radiofrequency ablation \[RFA\]). 5. Patient meets below conditions by blood test, kidney and liver function test: White blood cell (WBC) count \> 3,000/μL Absolute neutrophil count (ANC) ≥ 1,500/μL Hemoglobin (Hb) ≥ 9.0 g/dL Thrombocyte count \> 50,000/μL Blood urea nitrogen (BUN) and serum Creatinine ≤ 1.5× Upper Limit of Normal (ULN) AST and ALT ≤ 5×ULN 6. Female patient with childbearing potential should be confirmed of not being pregnant at the screening and during the study.
Exclusion criteria
for Donor 1. Patient with syphilis, human immunodeficiency virus I/II (HIV-I/II), human T-lymphotropic virus I/II (HTLV-I/II), or an increased risk (or has been diagnosed) for human transmissible spongiform encephalopathy (TSE); including Creutzfeldt-Jakob disease (CJD) 2. Patient with ongoing active hepatitis including acute or active chronic HBV/HCV infection, alcohol-associated hepatitis, and autoimmune hepatitis, etc., according to site-specific diagnostic criteria and laboratory parameters at screening 3. Patient who has clinically significant and unstable gastrointestinal, renal, endocrine, pulmonary, or cardiovascular disease judged by the investigator 4. Patient who has disease history of malignancy other than HCC except for curatively treated non-melanoma skin cancer, cervical carcinoma in situ, or superficial bladder tumors within 5 years before participating in this clinical trial 5. Patient who has medical history of immune deficiency or auto-immune disease (including but not limited to: rheumatoid arthritis , Burger's disease, multiple sclerosis and Type I diabetes) 6. Patient with the following medication or treatment should be excluded as the donor: 1. Systemic corticosteroids within 4 weeks prior to blood collection 2. Immunosuppressive treatment within 4 weeks prior to blood collection 3. Other anti-cancer treatments within 3 months prior to blood collection 4. Attenuated vaccines within 4 weeks prior to blood collection 7. Patient who has participated in other investigational studies and received any investigational therapy within 4 weeks prior to blood collection 8. Patient who has known or suspected hypersensitivity to any ingredient in the product (e.g. kanamycin, streptomycin or albumin, etc.) Inclusion Criteria for subject 1. Patient must be able to understand and has signed the informed consent documents and been aware of the investigational nature of the study. 2. Patient who has the histopathological or cytological proof (e.g. liver biopsy test) of HCC in the stage of I, II or IIIa. Patient's tumor has been totally removed by curative treatment (surgical operation, PEI, MWA or RFA) in 12 weeks based on the agreement date for written consent and the tumor's removal should be perfectly confirmed by medical imaging (Computed tomography (CT) scan or Magnetic resonance imaging (MRI)) within 4 weeks of first dosing. 3. Hepatic function of Child-Pugh class A 4. ECOG Performance status (ECOG-PS) score ≤ 1 5. Patient's remaining life-time is expected at least more than 3 months. 6. Patient meets below conditions by blood test, kidney and liver function test: WBC count \> 3,000/μL ANC ≥ 1,500/μL Hb ≥ 9.0 g/dL Thrombocyte count \> 50,000/μL BUN and serum Creatinine ≤ 1.5× ULN AST and ALT ≤ 5×ULN 7. Female patient with childbearing potential should be confirmed of not being pregnant or not lactating at the screening and during the study. 8.
