Chimeric Antigen Receptor (CAR) T Cell Therapy With YESCARTA in the Outpatient Setting

Primary Objectives

• To explore the feasibility of treating subjects with YESCARTA in the outpatient setting and guide the development of a subsequent, larger study that will determine the tolerability and safety profile of YESCARTA in the outpatient setting.
• To determine the time to specific interventions post infusion and the number of subjects who remain outpatient through 72 hours, 7, 14, and 30 days.

Secondary Objectives:

• Identify risk factors that preclude outpatient administration, and to obtain clinical data that will guide the development of guidelines by which YESCARTA treatment in the outpatient setting can be done safely.
• Assess the impact of close monitoring with telemedicine and twice-daily physical exam on specific outcomes including CRS and ICANS in subjects treated with YESCARTA in the outpatient setting.
• Cumulative steroid exposure within 28 days post YESCARTA infusion.
• To calculate the estimated cost of YESCARTA administered in the outpatient setting.

Exploratory Objectives:

• Time from YESCARTA infusion to the following: fever, fever with neutropenia, fever without neutropenia.
• Time from fever to Tocilizumab, fever to ICU admission, fever to low BP, fever to IV Fluid, fever to vasopressor, fever to onset to arrhythmias and fever to hospitalization.
• Calculate modified Neutropenic Fever Symptom Burden (NFSB) score for days 1-3 for each subject. Appendix D
• Obtain subject reported outcomes measured by Subject-Reported Outcomes Measurement Information System (PROMIS; Appendix F) [16, 17]
• Feasibility of using wearable devices to monitor vital signs in the outpatient setting. Data collected are for research only

Inclusion criteria

Or

Chemotherapy refractory disease evidenced by lack of adequate response to first line therapy. This consists of either progressive disease as best response to first line therapy or stable disease as best response after 4 cycles of appropriate chemotherapy

Or

Refractory after autologous stem cell transplant (ASCT) at any time point

And

Eastern Cooperative Oncology Group (ECOG) performance status 0-2.

Adequate hematologic, hepatic, renal and cardiac function evidenced by:

• absolute neutrophil count (ANC) ≥1000/µL
• Platelet ≥ 75,000/ µL
• T-bilirubin ≤ 1.5 mg/dL
• Normal serum creatinine or creatinine clearance ≥ 60 mL/min/1.73 m2
• Cardiac ejection fraction ≥ 50%
• Serum alanine aminotransferase/aspartate aminotransferase (ALT/AST) ≤ 5 times upper limit of normal (ULN).
• At least 1 measurable lesion
• Baseline oxygen saturation ≥92% on room air.
• Ability to stay at a distance which allows for subjects to come in and for specific interventions like antibiotics and tocilizumab to be started in 1 hour or less. This is approximately 30 miles of Vanderbilt.
• A caregiver who can be educated to operate equipment for vital signs monitoring.

Caregiver Eligibility:

Willingness to serve as a caregiver Ability to read, write and operate a phone Willingness to be taught to operate electronic device Willingness and ability to assist subject to wear electronic device such including patch, blood pressure machine, thermometer Pass caregiver assessment test

Subject and caregiver willing to be taught to operate an iPad or other electronic media for telemedicine, use wearable devices, and pass the caregiver competence test.

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.

Known CD19 negative tumor.

History of Richter's transformation of chronic lymphocytic leukemia (CLL).

Autologous stem cell transplant with therapeutic intent within 6 weeks of planned YESCARTA infusion.

History of allogeneic stem cell transplantation.

Prior CAR therapy or other genetically modified T-cell therapy.

History of severe, immediate hypersensitivity reaction attributed to aminoglycosides.

Presence or suspicion of fungal, bacterial, viral, or other infection that is uncontrolled or requiring IV antimicrobials for management. Simple urinary tract infection (UTI) and uncomplicated bacterial pharyngitis are permitted if responding to active treatment and after consultation with the sponsor's medical monitor.

History of human immunodeficiency virus (HIV) infection or acute or chronic hepatitis B or hepatitis 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 or applicable country guidelines.

Presence of any in-dwelling line or drain (e.g., percutaneous nephrostomy tube, in-dwelling Foley catheter, biliary drain, or pleural/peritoneal/pericardial catheter). Dedicated central venous access catheters, such as a Port-a-Cath or Hickman catheter, are permitted.

Subjects with detectable cerebrospinal fluid malignant cells, or brain metastases, or with a history of central nervous system (CNS) lymphoma or primary CNS lymphoma, cerebrospinal fluid malignant cells or brain metastases. Patients with treated secondary CNS involvement of lymphoma are allowed.

History or presence of CNS disorder, such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, progressive multifocal leukoencephalopathy, or any autoimmune disease with CNS involvement if it impairs ability to complete an effective and reliable neurological assessment.

Subjects with cardiac atrial or cardiac ventricular lymphoma involvement.

History of myocardial infarction, cardiac angioplasty or stenting, unstable angina, or other clinically significant cardiac disease within 12 months of enrolment.

Requirement for urgent therapy due to tumor mass effects (e.g., blood vessel compression, bowel obstruction, or transmural gastric involvement).

Primary immunodeficiency.

Any medical condition likely to interfere with assessment of safety or efficacy of study treatment.

Live vaccine ≤ 6 weeks prior to planned start of conditioning regimen.

History of severe immediate hypersensitivity reaction to any of the agents used in this study.

Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the preparative chemotherapy on the fetus or infant. Females who have undergone surgical sterilization or who have been postmenopausal for at least 2 years are not considered to be of childbearing potential.

Subjects of both genders who are not willing to practice birth control from the time of consent through 6 months after the completion of conditioning chemotherapy.

In the investigator's 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 (e.g. Crohn's, rheumatoid arthritis, systemic lupus) resulting in end organ injury or requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years.

Must not have received immunomodulating agents including checkpoint inhibitors, Bruton tyrosine kinase (BTK) inhibitors, and Revlimid within 2 months or 5 half-lives whichever is shorter.
