16. The last treatment for the subject before signing the informed consent was bcl-2 targeted drug treatment (if the subject had received bcl-2 inhibitor treatment but did not develop drug resistance, it could be included in this study).
17. History of secondary active malignancies within the past 2 years. However, adequately treated superficial skin cancer other than melanoma, in-situ cervix cancer more than 4 weeks, or prostate cancer not requiring any treatment and under surveillance prior to enrollment will not be considered exclusionary.
