This is a Phase I, open-label study to explore the safety profile and to find the maximum tolerated dose (MTD) or maximum feasible dose (MFD) of Magicell-NK in subjects diagnosed with stage I or stage IIa colon cancer post resection from a single site in Taiwan.
During this study, 3 dose levels of Magicell-NK will be tested with a 3+3 design to determine the MTD/MFD: Cohort 1, low dose (2×10\^8 cells), Cohort 2, middle dose (6×10\^8 cells), and Cohort 3, high dose (12\~18 ×10\^8 cells).
A dated and signed informed consent
Either gender and aged over 20 years old (inclusive) at date of consent
With histologically confirmed stage I or stage IIa colon cancer
Received curative colon resection within 4~8 weeks prior to the screening visit and does not need adjuvant chemotherapy or radiotherapy
Received any other investigational, anti-neoplastic medication (except squamous cell carcinoma, basal cell carcinoma, or carcinoma in situ of the skin, curatively treated with cryosurgery or surgical excision only), or immune cell therapy within 28 days prior to Day 1.
Currently under immunosuppressive or systemic steroid treatment with equivalent dosage higher than prednisolone 30 mg/day for more than 7 days within 14 days prior to Day 1
With known tumor metastasis or coexisting malignant disease
With ongoing acute diseases, or within the past 2 years having serious medical conditions (e.g. concomitant illness) such as cardiovascular (e.g. New York Heart Association grade III or IV), hepatic (e.g. Child-Pugh Class C), psychiatric condition (e.g. alcoholism, drug abuse), medical history, physical findings, or laboratory abnormality that, judged by the investigator, could interfere with the results of the trial or adversely affect the safety of the subject
