Third-Party Natural Killer Cells and Mogamulizumab for the Treatment of Relapsed or Refractory Cutaneous T-cell Lymphomas or Adult T-Cell Leukemia/Lymphoma
What this study is about
This phase I trial is to find out the best dose, possible benefits and/or side effects of third-party natural killer cells in combination with mogamulizumab in treating patients with cutaneous T-cell lymphoma or adult T-cell leukemia/lymphoma that has come back (relapsed) or does not respond to treatment (refractory).
View original scientific description
This phase I trial is to find out the best dose, possible benefits and/or side effects of third-party natural killer cells in combination with mogamulizumab in treating patients with cutaneous T-cell lymphoma or adult T-cell leukemia/lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Immunotherapy with third-party natural killer cells, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Mogamulizumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving third-party natural killer cells in combination with mogamulizumab may kill more cancer cells.

Primary outcome measures
Incidence of adverse events
Time frame: Up to day 84
Toxicities will be captured by Common Terminology Criteria for Adverse Events version 5. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns. The incidence of severe adverse events or toxicities will be described. Will assess the proportion of patients who experience grade 3 or higher non-hematologic toxicity.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Able to understand and voluntarily sign an informed consent form
- Age \>= 18 years at the time of signing the informed consent form
- Able to adhere to the study visit schedule and other protocol requirements
- Biopsy-proven, measurable, stage IB-IVB relapsed or refractory cutaneous T-cell lymphoma after 1 prior line of systemic therapy
- Note: extracorporeal photopheresis will be considered a systemic therapy for this study
- Patients with large cell transformation of cutaneous T cell lymphoma are eligible
- Patients with adult T-cell leukemia/lymphoma (ATLL) of any stage and any subtypes. Patient must have had at least one standard chemotherapy and measurable disease at the time of enrollment
- Patients who relapsed after autologous or allogeneic stem cell transplant are eligible
- All cancer therapy, including radiation, topical steroid, and chemotherapy must have been discontinued at least 1 week or 3 half-lives whichever is the longest prior to treatment in this study. The only exceptions are participants who are symptomatic from their skin lesions and have been on corticosteroids for prolonged periods of time (\> 60 days) without change. These patients may continue use of either systemic steroids (equivalent to \< 10 mg per day of prednisone) or topical steroids if the frequency and dosage steroids has not changed for 21 days prior to the study. These participants should continue on the same dose of systemic/topical steroid throughout the study period unless they achieve a complete response at which time steroids can be tapered or discontinued. Patients are allowed to continue any medications with known activity in T cell lymphomas at the pre-enrollment doses for conditions other than T cell lymphomas (ie, steroids for sarcoidosis), as long as there is evidence of T cell lymphoma progression while patients were on these agents
- Eastern Cooperative Oncology Group (ECOG) performance status of =\< 1 at study entry
- Absolute neutrophil count \>= 1000/mm\^3
- Platelet count \>= 50,000/mm\^3
- Total bilirubin =\< 2 x upper limit of normal (ULN)
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\]) and Alanine Aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) =\< 3 x ULN
- AST (SGOT) and ALT (SGPT) =\< 5 x ULN in patients with documented hepatic involvement by lymphoma
- Calculated creatinine clearance \>= 50 ml/min (by the Crockroft-Gault equation)
- Disease free of prior malignancies for \>= 2 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma in situ of the cervix or breast. Patients with early stage of prostate cancer under clinical surveillance without therapy are eligible. Patients with B-cell lymphomas treated with curative intent, and in remission for at least 2 years, may be in included (after discussion with principal investigator \[PI\])
- Negative serum pregnancy test at the time of enrollment for females of childbearing potential. Women who can get pregnant and men with partners who can become pregnant will be asked to practice a highly effective method of birth control while participating in the study that is considered medically acceptable by the study doctor.
- Life expectancy \>= 90 days
Exclusion criteria
- Investigational therapies in the 2 weeks prior to beginning treatment on trial
- Patients with active central nervous system (CNS) involvement with lymphoma
- Patients with known human immunodeficiency virus (HIV) infection with CD4 \< 350
- Patients who had solid organ transplants
- Evidence of active hepatitis B infection, based on positive surface antigen or hepatitis B deoxyribonucleic acid (DNA) polymerase chain reaction (PCR), or active hepatitis C infection based on positive PCR. Patients who are hepatitis B core antibody positive must take prophylaxis with lamivudine or equivalent and be willing to undergo monthly hepatitis B DNA PCR testing
- Present or history of progressive multifocal leukoencephalopathy (PML)
- Active grade II-IV acute or extensive chronic graft versus (vs.) host disease (GVHD)
- Patients may take steroids at any dose for disease control up to 24 hours prior to study enrollment. Steroids must have been discontinued at least 1 week or 3 half-lives whichever is the longest prior to treatment in this study, per inclusion criteria above. Topical steroids are allowed for CTCL patients
- Any illness, medical condition or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety
- A cardiovascular disability status of New York Heart Association class \>= 2
- History of severe allergic reactions to humanized monoclonal antibodies

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
