CAR-T-cell Treatment for Untreated High Risk MANtle Cell Lymphoma

Summary

First-line CAR-T-cell consolidation after an abbreviated induction with 2 cycles of Rituximab and Ibrutinib prior to CAR-T-cell treatment and followed by 6 months of maintenance with Ibrutinib in patients with high risk MCL.

Sexually active men and women of child-bearing potential must agree to use one of the highly effective contraceptive methods (combined oral contraceptives using two hormones, contraceptive implants, injectables, intrauterine devices, sterilized partner) together with one of the barrier methods (latex condoms, diaphragms, contraceptive caps) while on study; this should be maintained for 6 months after the last dose of KTE-X19 or for 3 months after last dose of Ibrutinib, whichever is longer
12. Negative serum or urine pregnancy test (Females of childbearing potential only, Females who have undergone surgical sterilization or who have been postmenopausal for at least 2 years are not considered to be of childbearing potential)
13. Willingness not to drive a motor vehicle for 8 weeks post CAR T cell treatment
14. Possibility to reach the site within 2 hours in case of toxicity / emergency

Exclusion Criteria:

1. Subjects not able to give consent
2. Subjects without legal capacity, unable to understand the nature, scope, significance and consequences of this clinical study
3. Known history of hypersensitivity to the investigational drug, to drugs with a similar chemical structure or to aminoglycosides
4. Simultaneously active participation in another clinical study involving an investigational medicinal product within 30 days prior to enrollment. Patients included in follow up periods of other clinical trials without ongoing trial medication are allowed
5. Subjects with a physical or psychiatric condition which at the investigator's discretion may put the subject at risk, may confound the study results, or may interfere with the subject's participation in this clinical study
6. Known or persistent abuse of medication, drugs or alcohol
7. Serious concomitant disease interfering with a regular therapy according to the study protocol:

   I. Clinically significant cardiovascular disease such as symptomatic arrhythmias, congestive heart failure, higher grade AV-block, unstable angina, myocardial infarction, cardiac angioplasty or stenting within 12 months of Screening, or any Class 3 (moderate) or Class 4 (severe) cardiac disease as defined by the New York Heart Association Functional Classification or LVEF below 50% II. Baseline oxygen saturation ≤ 92% on room air III. Clinical significant pleural effusion (if not lymphoma related) IV. Endocrinological (severe, not sufficiently controlled diabetes mellitus)
8. Current or planned pregnancy or nursing women. History of or active malignancy other than MCL, non-melanoma skin cancer, carcinoma in situ (e.g. cervix, bladder, breast) or prostate cancer unless disease-free for at least 3 years (and PSA within normal range in case of prostate cancer).
9. Presence of fungal, bacterial, viral, or other infection that is uncontrolled or requiring intravenous (IV) antimicrobials for management.
10. Positive test results for chronic HBV infection (defined as positive HBsAg serology) (mandatory testing) Patients with occult or prior HBV infection (defined as negative HBsAg and positive total HBcAb) may be included if HBV DNA is undetectable
11. Positive test results for hepatitis C (mandatory hepatitis C virus \[HCV\] antibody serology testing). Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA
12. Patients with known HIV infection (mandatory test)
13. History or presence of CNS disorder, such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, cerebral edema, posterior reversible encephalopathy syndrome, or any autoimmune disease with CNS involvement
14. History of or active autoimmune disease (e.g. Crohn's disease, rheumatoid arthritis, systemic lupus) resulting in end organ injury or requiring systemic immunosuppression / systemic medication within the last 2 years
15. History of deep vein thrombosis or pulmonary embolism requiring therapeutic anticoagulation within 6 months of enrolment
16. Known severe primary immunodeficiency
17. Any medical condition likely to interfere with assessment of safety or efficacy of study treatment
18. Live vaccine ≤ 6 weeks prior to planned start of study treatment
19. Any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow up schedule
