Engineered immune cells take on Hard-to-Treat blood cancers

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

If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required * REGISTRATION: Provide written informed consent understand and comply with protocol-required study procedures * REGISTARTION: Patients must have an ejection fraction (EF) of ≥ 45% * REGISTRATION: Patients must have pulse ox measurements of \> 92% on room air * REGISTRATION: Willingness to provide mandatory blood specimens for correlative research * REGISTRATION: Willing to return to enrolling institution for study follow-up Exclusion Criteria: * PRE-REGISTRATION: Prior solid organ transplantation * PRE-REGISTRATION: Unstable angina, clinically significant arrhythmia, or myocardial infarction ≤ 6 months of prior to pre-registration, or grade 3 or higher pericardial effusion at the time of pre-registration * PRE-REGISTRATION: Prior anti-BAFF-R therapies * PRE-REGISTRATION: Known contraindication to lymphodepleting (LD) chemotherapy * PRE-REGISTRATION: Use of systemic antitumor therapy or investigational agent ≤ 14 days, prior to pre-registration * PRE-REGISTRATION: Receiving any other investigational agent which would be considered as a treatment for the BAFF-R * PRE-REGISTRATION: Autologous HCT ≤ 60 days prior to pre-registration * PRE-REGISTRATION: Uncontrolled intercurrent non-cardiac illness including, but not limited to: * Previous or concurrent malignancy * Ongoing or active infection * Psychiatric illness/social situations * Dyspnea at rest due to complications of advanced malignancy or other disease that requires continuous oxygen therapy \* Persons of childbearing potential who are pregnant or breastfeeding * Life Expectancy of \< 6 weeks * Persons requiring systemic corticosteroids (\>10 mg prednisone or equivalent per day) and/or other immunosuppressive therapy.
