• 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)
• Patient who has clinically significant and unstable gastrointestinal, renal, endocrine, pulmonary, or cardiovascular disease judged by the investigator

Lab values

• 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
• Patient who has known or suspected hypersensitivity to any ingredient in the product (e.g. kanamycin, streptomycin or albumin, etc.)
• 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.
• Patient who has known or suspected hypersensitivity to any ingredient in the product (e.g. kanamycin, streptomycin or albumin, etc.)

Other

• Patient who fails to provide blood collection as a self-donor whose blood collection sample fails to generate adequate amount of ATL
• Patient who is not able to take MRI or CT scan examination
• Patient who has serious mental, social or psychological factors that may interfere with compliance and assessments of the study in the investigator's opinion

• Patients must be able to understand and sign the informed consent documents and aware of the investigational nature of the study.
• Patient is ≥ 20 years old.
• 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).
• 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 \[RFA\]).
• 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
• Female patient with childbearing potential should be confirmed of not being pregnant at the screening and during the study.
• Patient must be able to understand and has signed the informed consent documents and been aware of the investigational nature of the study.
• 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.
• Hepatic function of Child-Pugh class A
• ECOG Performance status (ECOG-PS) score ≤ 1
• Patient's remaining life-time is expected at least more than 3 months.
• 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
• Female patient with childbearing potential should be confirmed of not being pregnant or not lactating at the screening and during the study.
• Patient is willing to comply with protocol-stated requirements, instructions and restrictions.
• All male and female patients with child-bearing potential (between puberty and 2 years after menopause) are willing to use at least any one of the appropriate contraception methods shown below, for during and at least 24 weeks after ATL treatment.
  • Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception).
  • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
  • Male sterilization (at least 6 months prior to screening). For female subjects on the study, the vasectomized male partner should be the sole partner for that subject
  • Combination of any two of the following listed methods: (d.1+d.2 or d.1+d.3, or d.2+d.3):
  • d.1Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate \<1%), for example hormone vaginal ring or transdermal hormone contraception.
  • d.2Placement of an intrauterine device (IUD) or intrauterine system (IUS). d.3Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps).
