Pregnant or nursing (lactating) women Note: Women of child-bearing potential must have a negative serum pregnancy test performed within 24 hours before leukapheresis

Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception starting from the time of informed consent form (ICF) signature and for: - at least 12 months after the tisagenlecleucel infusion and until CART cells are no longer present by qPCR on two consecutive tests for patients in Arm A or patients who crossover. - a duration according to local label and physician recommendations for patients randomized to Arm B (SOC). Furthermore, patients may need to also add barrier contraception methods if required by the local label. Highly effective contraception methods include: - Total abstinence (when this is in line with the preferred and usual lifestyle of the participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception - Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or bilateral tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment - Male sterilization (at least 6 months prior to screening). For female participants on the study, the vasectomized male partner should be the sole partner for that participant - Use of oral, (estrogen and progesterone), injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception. - In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment. - Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or bilateral tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential. Note: If local regulations deviate from the contraception methods listed above to prevent pregnancy, local regulations apply and will be described in the ICF. In addition, participants must not donate oocytes.

Sexually active males who do not use a condom during intercourse starting from the time of ICF signature and for: - at least 12 months after the tisagenlecleucel infusion and until CAR T-cells are no longer present by qPCR on two consecutive tests for patients in Arm A or patients who crossover. - a duration according to local label and physician recommendations for patients randomized to Arm B (SOC) A condom is required for all sexually active male participants to prevent them from fathering a child AND to prevent delivery of study treatment via seminal fluid to their partner. In addition, participants must not donate sperm.

Prior treatment with anti-CD19 therapy, adoptive T cell therapy, or any prior gene therapy product
