Phase I Clinical Trial of Human AntiCD19 Chimeric Antigen Receptor T Cells for Treatment of Relapsed or Refractory Lymphoid Malignancies (Non-Hodgkin Lymphoma, Acute Lymphoblastic Leukemia, Chronic Lymphocytic Leukemia)

Who is this study for? Patients with relapsed or refractory lymphoid malignancies
What treatments are being studied? Human AntiCD19 Chimeric Antigen Receptor T Cells
Status: Suspended
Location: See location...
Intervention Type: Biological, Drug
Study Type: Interventional
Study Phase: Phase 1
SUMMARY

The purpose of this study is to determine if it is possible to treat relapsed or refractory lymphoid malignancies (Non-Hodgkin Lymphoma, Acute Lymphoblastic Leukemia, Chronic Lymphocytic Leukemia) with a new type of T cell-based immunotherapy (therapy that uses the immune system to treat the cancer).

Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:

• Must have relapsed or refractory non-Hodgkin lymphoma (NHL) (Group A - NHL/CLL), chronic lymphocytic leukemia (Group A - NHL/CLL) or acute lymphoblastic leukemia (Group B - ALL) treated with at least two lines of therapy. Disease must have either progressed after the last regimen or presented failure to achieve complete remission with the last regimen.

• The participant's malignancy is CD19 positive, either by immunohistochemistry or flow cytometry analysis on the last biopsy available or peripheral blood for circulating disease.

• Eastern Cooperative Oncology Group (ECOG) Performance status ≤ 2

• Total bilirubin ≤ 1.5 times the institutional upper limit of normal unless bilirubin rise is due to Gilbert's syndrome (maximum 2 time normal) or of non-hepatic origin

• AST (SGOT) ≤ 3 times institutional upper limit of normal

• ALT (SGPT) ≤ 3 times institutional upper limit of normal

• Serum Creatinine ≤ 2 times the institutional upper limit of normal and creatinine clearance ≥ 30 mL/min (calculated or measured)

• Must have adequate pulmonary function as defined as pulse oximetry ≥ 92% on room air.

• Must have adequate cardiac function as defined as left ventricular ejection fraction≥ 40% in the most recent echocardiogram.

• Absolute Lymphocyte Count \>100/microliter (uL)

• Participants (or legal guardians) must have the ability to understand and the willingness to sign a written informed consent document.

• For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of \< 1% per year during the treatment period and for at least 90 days after the human anti-CD19 CAR-T cell infusion. A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (\< 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of \< 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.

• For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below: With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of \< 1% per year during the treatment period and for at least 6 months after the human anti-CD19 CAR-T cell infusion. Men must refrain from donating sperm during this same period. With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 6 months after the human antiCD19 CAR-T cell infusion to avoid potential embryonal or fetal exposure. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods

Participants
Target number of participants: 36
Treatments
Experimental: Group A - NHL/CLL
Upon enrollment, peripheral blood mononuclear cells will be collected, and T-cell selection and manufacture of CAR-T cells will be done.~Participants will receive 60 mg/Kg/IV Cyclophosphamide on day -6 and 25 mg/m\^2 Fludarabine from day -5 to day -3.~Participants with CD19+ lymphomas and chronic lymphocytic leukemia will be enrolled on this arm sequentially in a 3 + 3 design starting with infusion of CAR-T cells at dose level 1 (DL1) on day 0.~The maximum tolerated dose (MTD) will be determined and then 6 additional participants will be enrolled at the MTD.
Experimental: Group B - ALL
Upon enrollment, peripheral blood mononuclear cells will be collected, and T-cell selection and manufacture of CAR-T cells will be done.~Participants will receive 60 mg/Kg/IV Cyclophosphamide on day -6 and 25 mg/m\^2 Fludarabine from day -5 to day -3.~Participants with Acute Lymphoblastic Leukemia (and lymphoblastic lymphoma as a solid tumor equivalent) will be enrolled on this arm sequentially in a 3 + 3 design starting with infusion of CAR-T cells at DL1 on day 0 and 7.~The maximum tolerated dose (MTD) will be determined and then 6 additional participants will be enrolled at the MTD.
