CD19/CD22 Chimeric Antigen Receptor (CAR) T Cells With or Without NKTR-255 in Adults With Recurrent or Refractory B Cell Malignancies

Trial ID or NCT#

NCT03233854

Status

not recruiting iconNOT RECRUITING

Purpose

This phase I trial studies the side effects of CD19/CD22 chimeric antigen receptor (CAR) T cells when given together with chemotherapy and NKTR-255, and to see how well they work in treating patients with CD19 positive B acute lymphoblastic leukemia that has come back or does not respond to treatment. A CAR is a genetically-engineered receptor made so that immune cells (T cells) can attack cancer cells by recognizing and responding to the CD19/CD22 proteins. These proteins are commonly found on diffuse large B-cell lymphoma and B acute lymphoblastic leukemia. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine phosphate, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. NKTR-255 is an investigational IL-15 receptor agonist designed to boost the immune system's natural ability to fight cancer. Giving CD19/CD22-CAR T cells and chemotherapy in combination with NKTR-255 may work better in treating patients with diffuse large B-cell lymphoma or B acute lymphoblastic leukemia.

Official Title

Phase 1 Dose Escalation Study of CD19/CD22 Chimeric Antigen Receptor (CAR) T Cells With or Without NKTR-255 in Adults With Recurrent or Refractory B Cell Malignancies

Eligibility Criteria

Ages Eligible for Study: Older than 18 Years
Sexes Eligible for Study: ALL
Accepts Healthy Volunteers: No
Exclusion Criteria:
  1. 1. History of other malignancy, unless disease free for at least 3 years. At the discretion of the Principal Investigator, subjects in remission for 1-2 years prior to enrollment may be deemed eligible after considering the nature of other malignancy, likelihood of recurrence during one year following CAR therapy, and impact of prior treatment on risk of CD19/CD22-CAR T cells. Subjects in remission \<1 year are not eligible.
    1. * Exception: Nonmelanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast) is eligible. * Hormonal therapy in subjects in remission \>1 year will be allowed.2. Presence of fungal, bacterial, viral, or other infection that is uncontrolled. Simple UTI and uncomplicated bacterial pharyngitis are permitted if responding to active treatment.3. Known history of infection with any of the following:
    2. * HIV * Hepatitis B (HBsAg positive) * Hepatitis C virus (anti-HCV positive) A history of hepatitis B or hepatitis C is permitted if the viral load is undetectable per quantitative PCR and/or nucleic acid testing.4. Presence of a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with CNS involvement that in the judgment of the investigator may impair the ability to evaluate neurotoxicity.5. History of myocardial infarction, cardiac angioplasty or stenting, unstable angina, or other clinically significant cardiac disease within 12 months of enrollment6. Any medical condition that in the judgement of the investigator is likely to interfere with assessment of safety or efficacy of study treatment7. History of severe immediate hypersensitivity reaction to any of the agents used in this study8. Women who are pregnant or breastfeeding9. In the investigator's judgment, the subject is unlikely to complete all protocol-required study visits or procedures, including follow-up visits, or comply with the study requirements for participation.10. Previous treatment with interleukin-2 or interleukin-15.11. Confirmed diagnosis of relapsed/refractory biphenotypic BT cell ALL12. Primary immunodeficiency or history of autoimmune disease (e.g. Crohns, rheumatoid arthritis, systemic lupus) requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years
