The following drugs must be stopped > 4 weeks prior to CTL019 infusion: salvage chemotherapy (e.g. clofarabine, cytosine arabinoside > 100 mg/m2, anthracyclines, cyclophosphamide), excluding the required lymphodepleting chemotherapy drugs;
5.CNS disease prophylaxis: i. CNS prophylaxis treatment must be stopped > 1 week prior to CTL019 infusion (e.g. intrathecal methotrexate).
•Active CNS involvement by malignancy, defined as CNS-3 per National Comprehensive Cancer Network (NCCN) guidelines. Note: Patients with history of CNS disease that has been effectively treated will be eligible12. Patient has participated in an investigational research study using an investigational agent within the last 30 days prior to screening
•Pregnant or nursing (lactating) women. NOTE: female study participants of reproductive potential must have a negative serum or urine pregnancy test performed within 48 hours before infusion
•Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant and all male participants, unless they are using highly effective methods of contraception for a period of 1 year after the CTL019 infusion). Highly effective contraception methods include:
1.Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are NOT acceptable methods of contraception);
2.Female sterilization (have had surgical bilateral oophorectomy with or without 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 participants on the study the vasectomized male partner should be the sole partner for that patient;
4.BOTH of the following forms of contraception must be utilized: i. 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; ii. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository;
5.Use of intrauterine devices (IUDs) are excluded due to increased risks of infection and bleeding in this population; f). 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. And more,... |
