You likely can't join if

- Subject must have one or more measurable disease sites defined as follows: a. A positron emission tomography/computed tomography (PET/CT) scan demonstrating PET- positive lesion(s) AND b. At least one measurable nodal lesion (long axis > 1.5 cm and short axis > 1.0 cm) or ≥ one measurable extra-nodal lesion (long axis > 1.0 cm) on CT scan or MRI
- Ability to understand and willingness to sign written informed consent. Signed informed consent must be obtained before any study specific procedure
- Women of childbearing potential and sexually active men must practice a highly effective method of birth control during and after the study, consistent with local regulations regarding the use of birth control methods for subjects participating in clinical trials. Men with female partners who are of childbearing potential must agree to use a condom when sexually active or practice total abstinence from the time of giving informed consent until at least 7 months after the patient receives his last dose of study treatment. Men must agree not to donate sperm from the time of giving informed consent until at least 7 months after the patient receives his last dose of study treatment. For female subjects, they apply for 12 months after the last dose of the study drug
- Total bilirubin ≤ 1.5 times the upper limit of normal (ULN), except for patients with Gilbert syndrome, cholestasis due to hepatic hilum adenopathies or liver involvement, or biliary obstruction due to lymphoma, who may have a total bilirubin ≤ 3 times the ULN
- Women of childbearing potential participating in the study will be required to undergo a pregnancy test using either urine or serum beta-human chorionic gonadotropin (beta-hCG) at the screening visit. A negative result is necessary for inclusion in the study
- Acute toxicity (except alopecia, fatigue) of any prior lymphoma therapy should be resolved to Grade ≤ 1 (with the exception of prior CRS or ICANS that should be fully resolved) at study screening
