 (submitted: October 29, 2020)
  • Overall Remission Rate (ORR) Per Independent Review Committee (IRC) (for ALL Participants) [ Time Frame: within 6 months after CTL019 infusion ]
    ORR is defined as the percentage of participants with a best overall disease response of complete remission (CR) or Complete remission with incomplete blood count recovery (CRi), where the best overall disease response is defined as the best disease response recorded from CTL019 infusion until the start of new anticancer therapy. Best response was assigned in the following order: CR, CRi, CR or CRi with residual mediastinal disease, No response and Unknown.
  • Overall Remission Rate (ORR) Per Local Investigator Assessment (for Lymphoblastic Lymphoma Patients Only) [ Time Frame: 6 months after CTL019 ]
    Overall Remission Rate (ORR), which includes Complete Remission (CR) and Complete Remission with Incomplete Blood Count Recovery (CRi), as determined by assessments of peripheral blood, bone marrow, CNS symptoms, physical exam (PE) and cerebrospinal fluid (CSF). This primary endpoint was based on the local investigator assessment. No participants with lymphoblastic lymphoma were infused in this study.

Highly effective contraception methods include:

    2. Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy, or 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
    3. Male sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner should be the sole partner for that patient
    4. Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception
    5. Use of IUDs are excluded due to increased risks of infection and bleeding in this population. However, IUD inserted prior to consent may remain in place, and a second method of contraception is mandated
    6. In case of use of oral contraception, women must be stable on the same pill for a minimum of 3 months before taking study treatment.

Women who are not of reproductive potential (defined as either <11 years of age, Tanner Stage 1, post-menopausal for at least 24 consecutive months (i.e. have had no menses) or have undergone hysterectomy, bilateral salpingectomy, and/or bilateral oophorectomy) are eligible without requiring the use of contraception. Women who are not yet of reproductive potential are to agree to use acceptable forms of contraception when they reach reproductive potential if within 1 year of CTL019 or if CAR cells are present in the blood by PCR. Acceptable documentation includes written or oral documentation communicated by clinician or clinician's staff of one of the following:

  1. Demographics show age < 11
  2. Physical examination indicates Tanner Stage 1
  3. Physician report/letter
