Females of childbearing potential must have a negative serum pregnancy test within 3 days prior to registration

NOTE: Females are considered of childbearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least 12 consecutive months. Documentation of postmenopausal status must be provided
Females of childbearing potential must be willing to abstain from heterosexual activity or to use 2 forms of effective methods of contraception from the time of informed consent until 12 months after treatment the last dose of siltuximab. The two contraception methods can be comprised of two barrier methods, or a barrier method plus a hormonal method or an intrauterine device that meets < 1% failure rate for protection from pregnancy in the product label
Male subjects with female partners must have had a prior vasectomy or agree to use an adequate method of contraception (i.e., double barrier method: condom plus spermicidal agent) starting with the first dose of study therapy through 12 months after the last dose of siltuximab
Subjects with prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the experimental regimen are eligible for the trial
Subject is willing and able to comply with study procedures based on the judgement of the investigator or protocol designee
FOR SILTUXIMAB TREATMENT OF CRS/ICANS: Any subject with grade 1 ICANS lasting > 12 hours
FOR SILTUXIMAB TREATMENT OF CRS/ICANS: Any subject with grade >= 2 CRS after CD19.CAR-T cell therapy
FOR SILTUXIMAB TREATMENT OF CRS/ICANS: Any subject with grade >= 2 CRS after CD19.CAR-T cell therapy with concurrent ICANS
SECOND SILTUXIMAB TREATMENT DOSE FOR CRS/ICANS: Subjects meeting criteria for a treatment dose who have received a treatment dose and have no change in the CRS or ICANS grade after 12 hours

Exclusion Criteria:

Subjects requiring daily corticosteroids at a dose > 10mg of prednisone per day (orequivalent). Pulsed steroids for disease control are acceptable
Subjects who are planned to receive prophylactic steroids for mitigating CRS/ICANS before, during, or after CD19.CAR-T infusion
Active central nervous system or meningeal involvement by lymphoma. Subjects with symptoms of possible central nervous system (CNS) disease should undergo CNS workup with magnetic resonance imaging (MRI) brain and diagnostic lumbar puncture prior to enrollment on this study.
