A Multi-center, Single-arm, Open, Phase I/IIa Clinical Trial to Evaluate the Efficacy and Safety of EBViNT Cell (EBV Specific Autologous CD8+ T Cell) in Patients With Treatment Failed Epstein Barr Virus (EBV)-Positive Malignancies
EBV Associated Extranodal NK/T-cell Lymphoma, EBV-Associated GastricCarcinoma or Esophageal AdenoCarcinoma
About this trial
This is an interventional treatment trial for EBV Associated Extranodal NK/T-cell Lymphoma focused on measuring Cytotoxic T cell, Lymphoma, Immuno-oncology, ENKL, EBViNT, Gastric cancer, solid tumor, Esophageal AdenoCarcinoma
Eligibility Criteria
Inclusion Criteria (Visit 1)
- At least 19 years of age
Patients with lymphomas or solid tumors who have been found to be positive for EBV encoded RNA (EBER) by in situ hybridization (ISH) (previous test results may be used as evidence if available)
- Part 1: Histologically or cytologically confirmed lymphoma or solid tumor
- Part 2: Histologically or cytologically confirmed solid tumor
- Part 3: Patients who have been diagnosed with histologically confirmed extranodal NK/T-cell lymphoma (ENKL) according to WHO classification
- Parts 4 and 5: Patients with histologically confirmed gastric cancer or esophageal adenocarcinoma
- Patients who have given written consent to voluntarily participate in the epitope screening
Exclusion Criteria (Visit 1)
- Patients with aggressive NK cell leukemia
- Patients with hemophagocytic lymphohistiocytosis (HLH)
- Persons who have previously received a solid organ transplant
- Persons who have been diagnosed with a malignant tumor other than the target disease in the past 5 years (treated basal cell carcinoma, squamous epithelial cell carcinoma, and non-invasive cervical cancer do not necessitate exclusion)
- Patients in whom a tuberculosis infection was confirmed in the 1 year prior to screening for the present study (However, patients who have been determined to be cured after treatment may be enrolled.)
- Patients who test positive for anti-HIV antibodies
- Patients deemed unsuitable to participate in the clinical trial by an investigator based on active infection (HBV, HCV) test results
Enrollment Criteria (Visit 2)
- Persons who have been found to be capable of production in the epitope screening test
Patients who have failed standard treatment or conventional chemotherapy and who meet any one of the following
- Patients who have relapsed/progressed after 1 or more chemotherapies, and for whom standard treatment does not exist or cannot be performed
- Intolerable patients for whom anticancer treatment cannot be performed or a minimum of one full cycle cannot be completed in a first-line chemotherapy
- Patients who are refractory to first-line chemotherapy
Persons with evaluable lesions
- Lymphoma: Persons with at least 1 lesion with long axis > 15 mm or 18FDG-PET-CT avid
- Solid tumor: Persons with at least 1 measurable lesion based on RECIST 1.1
- Persons with appropriate liver, renal, and bone marrow function (two retests are permitted for borderline results, and corrections such as transfusion are permitted)
Exclusion criteria (Visit 2)
- Where central nervous system (CNS) lymphoma or uncontrolled CNS metastasis is present (patients with brain metastasis that has been treated and is stable [stable for at least 30 days based on radiology records] may be enrolled)
- Persons who have received surgery, radiotherapy, or chemotherapy in the 3 weeks prior to the investigational product administration
- Persons who have been administered any other investigational product in the 3 weeks prior to the investigational product administration
- Persons who have not recovered from the toxicity of any previous treatment to Grade 1 or lower based on NCI CTCAE v5.0 (however, clinically insignificant toxicities such as alopecia are excluded)
- Patients who have received immunosuppressants, including steroids, in the 10 days prior to blood collection (Visit 2) for production of the study drug (however, local steroids and steroids for inhalers are permitted, and steroid equivalent to 20 mg/day of prednisolone may be administered at the investigator's discretion)
Patients with the following (but not limited to) clinically significant cardiovascular comorbidities as determined by the investigator
: Uncontrolled hypertension (i.e., systolic pressure > 180 mmHg and/or diastolic pressure > 100 mm/Hg), unstable angina, pulmonary embolism, cerebrovascular disease, valvular disease, congestive heart failure (NYHA severity classification Grade III or IV), or myocardial infarction or serious cardiac arrhythmia within the 24 weeks prior to the enrollment visit
- Patients with findings of autoimmune or inflammatory disease, whose abnormal results from an autoimmune response test have been deemed clinically significant by an investigator
