Study of HBV-TCR T Cells (LioCyx-M) as Monotherapy or as Combination With Lenvatinib for HBV-related HCC

Prior treatment

• Local or loco-regional therapy of intrahepatic tumour lesions (e.g. surgery, radiation therapy, hepatic arterial embolization, chemoembolization, radiofrequency ablation, percutaneous ethanol injection, or cryoablation) must have been completed ≥4 weeks before the first infusion of LioCyx-M.
• Concurrent administration of any other anti-tumour therapy, including cytotoxic chemotherapy, tyrosine kinase inhibitor therapy, and immunotherapy.
• Treatment with anticancer therapy, including investigational therapy, within 2 weeks prior to first infusion. For prior therapies with a half-life longer than 3 days, discontinuation of the therapy must have occurred at least 28 days prior to leukapheresis.
• Treatment with other investigational therapy within 28 days prior to initiation of study treatment. Patients participating in surveys or observational studies are eligible to participate in this study.
• Likelihood to require any immunosuppressive treatments during the period of the clinical trial (Localized steroid use should be allowed)
• Significant cardiovascular disease (such as New York Heart Association (NYHA) Functional Classification Class II or greater cardiac disease, myocardial infarction, or cerebrovascular accident within 3 months prior to initiation of study treatment), unstable arrhythmia, or unstable angina

Other illness

• Second primary malignancy that is clinically detectable at the time of consideration for study enrolment, except for in situ carcinoma of the cervix, non-melanoma skin carcinoma localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer and superficial bladder tumours.
• Lack of peripheral venous or central venous access or any condition that would interfere with drug administration or collection of study samples
• History of severe allergic anaphylactic reactions to T cell therapy products and/or lenvatinib
• Human immunodeficiency virus (HIV) positive or active infection requiring treatment (except for HBV)
• Uncontrolled hypertension, defined as systolic blood pressure \>160 mmHg or diastolic pressure \>110 mmHg, despite optimal medical management

Other

• Brain metastasis

• Eastern Cooperative Oncology Group (ECOG) performance status ≤1
• Advanced HCC with diagnosis confirmed by histology/ cytology or clinically by AASLD criteria in cirrhotic patients.
• Disease that is not amenable to curative surgical and/or locoregional therapies, or progressive disease after surgical and /or locoregional therapies
• Patients who failed first-line systemic therapy for HCC
• Serum HBsAg positivity
• Non-cirrhotic or compensated cirrhosis Child-Pugh A (5 - 6 points)
• HLA class 1 profile matching HLA-class I restriction element of the available T cell receptor
