  • Once all other eligibility criteria are confirmed, must have an apheresis product of non-mobilized cells received and accepted by the manufacturing site. Note: Apheresis product will not be assessed for acceptance by the manufacturing site until documented confirmation of all other eligibility criteria.
  • Women of child-bearing potential (defined as all women physiologically capable of becoming pregnant) must agree to use highly effective methods of contraception during the entire study period (1 year after the CTL019 infusion). Highly effective contraception methods include:
  • 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)
  • 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

  • BOTH of the following forms of contraception must be utilized:
  • 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

  • Allogeneic cellular therapy: Any donor lymphocyte infusions (DLI) must be completed > 6 weeks prior to CTL019 infusion c. GVHD therapies: Any drug used for GVHD must be stopped > 4 weeks prior to CTL019 infusion (e.g. calcineurin inhibitors, methotrexate or other chemotherapy drugs, mycophenolyate, University of Pennsylvania Page 20 of 138 Oncology Protocol Protocol No. UPCC#07414/CCTL019B2207J V00.1 04-02-2014 steroids [see above], rapamycin, thalidomide, or immunosuppressive antibodies such as rituximab, anti-tumor necrosis factor [anti-TNF] , anti-interleukin 6 [anti-IL6] or anti-interleukin 6 receptor [anti-IL6R]) d. Chemotherapy: i. The following drugs must be stopped >1 week prior to CTL019 infusion: hydroxyurea, vincristine, 6-mercaptopurine, 6-thioguanine, methotrexate <25 mg/m2, cytosine arabinoside <10 mg/m2/day, asparaginase ii. The following drugs must be stopped >4 weeks prior to CTL019 infusion: salvage chemotherapy (e.g. clofarabine, cytosine arabinoside >100mg/m2, anthracyclines, cyclophosphamide), excluding the required lymphodepleting chemotherapy drugs e. CNS disease prophylaxis i. CNS prophylaxis treatment must be stopped > 1 week prior to CTL019 infusion (e.g. intrathecal methotrexate).
  • 11. Active Central Nervous System (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 eligible.
  • 12. Patient has received an investigational medicinal product within the last 30 days prior to screening 13. 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

The study will have the following sequential phases: Screening, Pre-Treatment, Treatment and Primary Follow-up, Secondary Follow-up (Relapse Follow-up) and Survival Follow-up. The total duration of the primary follow-up is 1 year from cell infusion. Safety will be assessed until the end of the treatment and primary follow-up phase.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CTL019 in people with B-cell Acute Lymphoblastic Leukemia and Relapsed B-cell Acute Lymphoblastic Leukemia, run by Abramson Cancer Center at Penn Medicine.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 23 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 14 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Adverse Events (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02167360.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Feb 2017.
