The investigator must discuss with the sponsor to determine whether a surgery is major surgery before enrolling the participant in the trial. 16.The participant has not recovered to Common Terminology Criteria for Adverse Events (CTCAE) v5.0 = Grade 1 from toxicities attributable to previous treatments, except for alopecia, peripheral neuropathy, and other events that, in the judgment of the investigator, are unlikely to result in lymphodepletion or cumulative toxicities of CT071 treatment; 17.Other conditions considered inappropriate for participation in this clinical trial by the investigator. |
