Study Arms (3)
ADI-001 Dose Escalation
EXPERIMENTALADI-001 is administered via infusion with ascending dose levels as a single dose to determine the maximum tolerated dose (MTD) or maximum assessed dose (MAD) of ADI-001 (Part 1a).
ADI-001 Dose Extension
EXPERIMENTALADI-001 is administered via infusion at MAD/MTD to evaluate the safety of multiple doses (Part 1b).
ADI-001 Dose Expansion
EXPERIMENTALDose Expansion ADI-001 is administered via infusion at the MTD/MAD to confirm recommended phase 2 dose (Part 2).

Eligibility Criteria
You may qualify if:
- Relapsed/refractory (R/R) previously treated B cell malignancies.
- Prior treatment must include at least 2 prior regimens, including anti CD20 antibody therapies. Prior Treatment with CD19 CAR T may be considered.
- Documented measurable disease as defined by Lugano 2014
- Male or female ≥ 18 years of age
- Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1
- Adequate hematological, renal, pulmonary, cardiac, and liver function
- Female patients who are not pregnant or breastfeeding
- Female patients of childbearing potential and all male patients must agree to use highly effective methods of birth control for the duration of the study.
You may not qualify if:
- Current or history of any of the following conditions:
- Central nervous system (CNS) primary lymphoma (current or history)
- Unrelated malignancy requiring systemic treatment (current or history \[in the past 3 years, other than hormonal treatment which is allowed\])
- Any of the following current conditions:
- Active acute or chronic graft versus host disease (GvHD) other than grade 1 with skin involvement, or GvHD requiring immunosuppressive treatment within 4 weeks of enrollment
- Any other acute or chronic medical or psychiatric condition that may increase the risk associated with study participation or investigational product administration
- Tumor mass effects such as bowel obstruction or blood vessel compression that require therapy
- Opportunistic infections
- History of any clinically significant conditions in the opinion of the Investigator
- Prior treatment with any of the following:
- a Gene therapy, genetically modified cell therapy, or adoptive T cell therapy within 6 weeks of study enrollment.
- b Radiation therapy within 4 weeks prior to study entry. Palliative local radiation may be allowed within 1 week prior to study entry.
- c Autologous stem cell transplant (SCT) within 6 weeks of planned ADI 001 infusion.
- d Allogeneic transplant and donor lymphocyte infusion within 3 months of planned CAR T cell infusion
- Patients unwilling to participate in an extended safety monitoring period (long term follow up \[LTFU\] protocol)
