Open-label, Phase 1 Study of CD19 t-haNK as a Single Agent and in Combination With an IL-15 Superagonist (N-803) and Rituximab in Subjects With Relapsed/Refractory Non-Hodgkin Lymphoma.
Open-label, Phase 1 Study of CD19 t-haNK as a Single Agent and in Combination With an IL-15 Superagonist (N-803) and Rituximab in Subjects With Relapsed/Refractory Non-Hodgkin Lymphoma. Up to 20 subjects will be enrolled and randomized 1:1 to 1 of 2 cohorts, as outlined below. The initial 3 subjects will be sequentially enrolled in a staggered fashion, with a 7 day interval between each subject to enable the capture and monitoring of any acute and subacute toxicities.
• Age ≥ 18 years old.
• Able to understand and provide a signed informed consent that fulfills the relevant Institutional Review Board (IRB) or Independent Ethics Committee (IEC) guidelines.
• Histologically documented CD19- and CD20-positive B-cell NHL with the following specific criteria:
∙ Have active disease after ≥ 2 lines of cytotoxic chemotherapy.
‣ Have received rituximab or another anti-CD20 antibody.
‣ Have either failed autologous transplant or are ineligible to receive autologous transplant.
‣ Have measurable disease by Lugano classification documented within 8 weeks of the time of consent, defined as nodal lesions \> 15 mm in the long axis or extranodal lesions \> 10 mm in long and short axis, or bone marrow involvement that is biopsy proven.
‣ Have CD19- and CD20-positive disease on most recent biopsy performed (a repeat biopsy is not mandatory for this study except as noted below). A minimum of 5% CD19 and CD20 positivity by immunohistochemistry or flow cytometry on prior or repeat biopsy is required.
• History of central nervous system (CNS) involvement with cerebral spinal fluid (CSF) analysis following magnetic resonance imaging (MRI) brain and lumbar puncture showing no evidence of CNS involvement by cytology and flow cytometry.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
• Expected survival \> 12 weeks.
• Willing and able to have central line placed for study drug infusions.
• Stated willingness to comply with study procedures.
• Able to attend required study visits and return for adequate follow-up, as required by this protocol.
⁃ Agreement to practice effective contraception for female subjects of child-bearing potential and nonsterile males. Female subjects of child-bearing potential must agree to use effective contraception while on study and for at least 5 months after the last dose of study drug. Nonsterile male subjects must agree to use a condom while on study and for up to 5 months after the last dose of study drug. Effective contraception includes surgical sterilization (eg, vasectomy, tubal ligation), two forms of barrier methods (eg, condom, diaphragm) used with spermicide, intrauterine devices (IUDs), and abstinence.
