Those who have been clinically aware of heart disease within 6 months prior to screening 2. Those identified as thromboembolic disease, pulmonary embolism or bleeding bleeding diatheses within 6 months prior to screening 3. Those who have identified a history of malignant tumors other than B-cell non-Hodgkin's lymphoma within five years prior to screening 4. Those who have undergone major surgery within 4 weeks prior to screening 5. Those who have undergone non-critical surgery within two weeks prior to screening * Childbearing women or men who do not have the will to use effective contraception for a longer period of time, either 12 months after clinical trial period and AT101 administration or when AT101 in the body is not identified * Those who have been administered or applied to other IP/ID within 4 weeks of screening * Those who are addicted to alcohol and/or medication * Those who are unfit or unable to participate in this trial when judged by PI
