A Phase 2 Trial of Emapalumab for the Prevention of CAR-T Cell Associated Toxicities

Description

This research study involves assessing the impact of emapalumab as preventative management of CAR-T related cytokine release syndrome in participants with Non-Hodgkin's lymphoma (NHL). The research study involves the following study interventions: * Fludarabine and cyclophosphamide (Lymphodepleting Chemotherapy) * Axicabtagene Ciloleucel * EmapalumabThis is a phase 2 multi-center, open label study that is evaluating the safety and efficacy of emapalumab in preventing toxicities associated with axicabtagene ciloleucel in subjects with second- or third-line large B-cell non-Hodgkin's lymphoma. A phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has not approved emapalumab for the participants specific disease, but it has been approved for other uses. The U.S. FDA has approved axicabtage

Trial Eligibility

Inclusion Criteria: * Adult patients with large B-cell lymphoma that is refractory to first-line chemoimmunotherapy or that relapses within 12 months of first-line chemoimmunotherapy. Or adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma. * At least 1 measurable lesion per Lugano at time of screening. * At least 2 weeks or 5 half-lives, whichever is shorter, must have elapsed since any prior systemic therapy at the time the subject is planned for leukapheresis, except for systemic inhibitory/stimulatory immune checkpoint therapy however steroids only require a 7-day washout. * At least 3 half-lives must have elapsed from any prior systemic inhibitory/stimulatory immune checkpoint molecule therapy at the time the subject is planned for leukapheresis (e.g. ipilimumab, nivolumab, pembrolizumab, atezolizumab, OX40 agonists, 4-1BB agonists, etc). * Age 18 or older * Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. * Adequate renal, hepatic, pulmonary and cardiac function defined as: * ANC ≥1000/uL * Platelet count ≥50,000/uL * Absolute lymphocyte count ≥100/uL * Creatinine clearance (as estimated by Cockcroft Gault or CKD-EPI) ≥ 30 mL/min * Serum ALT/AST ≤2.5 per institutional ULN * Total bilirubin ≤1.5 mg/dl, except in subjects with Gilbert's syndrome. * Cardiac ejection fraction ≥ 40%, no clinically significant pericardial effusion, and no clinically significant ECG findings * Baseline oxygen saturation \>92% on room air. * Females of childbearing potential must have a negative serum or urine pregnancy test (females who have undergone surgical sterilization or who have been postmenopausal for at least 2 years are not considered to be of childbearing potential). * Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria: * History of malignancy other than nonmelanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast) or follicular lymphoma unless disease free for at least 3 years. * History of Richter's transformation of CLL. * Autologous stem cell transplant within 6 weeks of planned axicabtagene ciloleucel infusion. * History of allogeneic stem cell transplantation. * Presence of uncontrolled fungal, bacterial, viral, or other infection at time of screening. * Known history of acute or chronic active hepatitis B or C infection. Subjects with history of hepatitis infection must have cleared their infection as determined by standard serological and genetic testing per current Infectious Diseases Society of America (IDSA) guidelines. * Patients should also be negative for latent Tb, CMV (NAT), EBV (NAT) and adenovirus (NAT) by PCR testing. * No evidence of active CNS disease regardless of prior CNS history. * History or presence of CNS disorder such as seizure disorder, cerebrovascular ischemia/hemorrhage within 6 months of enrollment. * History of myocardial infarction, cardiac angioplasty or stenting, unstable angina, or other clinically significant cardiac disease within 12 months of enrollment. * History of symptomatic pulmonary embolism within 3 months of enrollment; ongoing anticoagulation is allowed if beyond 3 months. * Any medical condition likely to interfere with assessment of safety or efficacy of study treatment. * History of allergic reactions or severe immediate hypersensitivity reaction to any of the agents used in this study or compounds of similar chemical or biologic composition. * Females who are pregnant or breastfeeding or female or male participants who are not willing to practice birth control from the time of consent through 6 months after the completion of axicabtagene ciloleucel * In the investigators judgment, the subject is unlikely to complete all protocol-required study visits or procedures, including follow-up visits, or comply with the study requirements for participation. * History of autoimmune disease requiring ongoing systemic immunosuppression. Steroids are allowed up to 5mg predinosine-equivalent for adrenal insufficiency. * Patients anticipated to require canakinumab, JAK inhibitors, TNF inhibitors, and tocilizumab for non-CAR-T management of baseline autoimmune/inflammatory disease at the time of emapalumab initiation. * Receipt of a BCG vaccine within 12 weeks prior to Screening. * Receipt of a live or attenuated live (other than BCG) vaccine within 4 weeks prior to screeing. * Participants who are receiving any other investigational agents for this condition.
