Could a super steroid tame blood cancers? new trial underway

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Females of childbearing potential and nonsterile males must agree to use medically effective methods of contraception from the time of informed consent/assent through 1 month after study drug infusion, which must, at a minimum, include a barrier method; and 8\. The ability to understand and willingness to sign a written informed consent form (ICF) and the ability to adhere to the study schedule and prohibitions. Patients under the age of 18 years (or other age as defined by regional law or regulation) must be willing and able to provide written assent and have a parent(s) or guardian(s) willing and able to provide written, signed informed consent after the nature of the study has been explained and prior to performance of any study-related procedure. Exclusion Criteria: * Patients who meet any of the following criteria will be excluded from participation in the study for Phase 2: 1. History of another malignancy, except for the following: * Adequately treated local basal cell or squamous cell carcinoma of the skin; * Adequately treated carcinoma in situ without evidence of disease; * Adequately treated papillary, noninvasive bladder cancer; or * Other cancer that has been in complete remission for ≥2 years. Patients with low-grade prostate cancer, on active surveillance, and not expected to clinically progress over 2 years are allowed; 2.
