Clinical Trial Summary

This is a Phase 1 open-label, study designed to characterize the safety, tolerability, and preliminary anti-tumor activity of memory-like natural killer cells (ML NK) in combination with nivolumab and relatlimab in subjects with advanced and/or metastatic melanoma. There will be two arms to test the variables of ML NK cell source. ML NK cells from an autologous source will be used for Arm 1, and ML NK cells from an allogenic source will be used for Arm 2. The investigators hypothesize that ML NK cells from either an autologous source or allogenic source are safe and tolerable in subjects with advanced and/or metastatic melanoma.

• Oxygen saturation = 90% on room air
• Ejection fraction = 45%
• Patients with a prior history of symptomatic CNS metastases must have received treatment and be neurologically stable for at least for 4 weeks and off anti-seizure medication and steroids for 7 days prior to initiation of LDC are eligible.
• Able to be off corticosteroids and any other immune suppressive medications for at least 14 days prior to apheresis or lymphodepletion and continuing until 30 days after the infusion of the ML NK cells. However, use of physiological dosing of corticosteroids (defined as =15mg prednisone or equivalent) is permitted if deemed medically necessary.
• Women of childbearing potential must have a negative pregnancy test within 28 days prior to study registration. Female and male patients (along with their female partners) must agree to use two forms of acceptable contraception, including one barrier method, during participation in the study and until 30 days after the last ML NK cells infusion.
• Life expectancy >12 weeks
• Ability to understand and willingness to sign an IRB approved written informed consent document

Exclusion Criteria:

• Active autoimmune disorder requiring immunosuppression (physiologic steroids defined as =15mg prednisone or equivalent are acceptable).
• Prior history of an immune-related Grade 3 or 4 AE attributed to prior cancer immunotherapy (other than endocrinopathy managed with either replacement therapy or asymptomatic elevation of serum amylase or lipase) that resulted in permanent discontinuation of the prior immunotherapeutic agent.
• Patients with Grade =2 irAE who have not completely recovered from irAE (i.e. have residual toxicities >Grade 1) related to prior cancer immunotherapy (other than endocrinopathy management with replacement therapy or stable vitiligo). Patients treated with corticosteroids for irAE must demonstrate absence of related signs or symptoms for =7 days following discontinuation of corticosteroids.
• Leptomeningeal disease, carcinomatous meningitis, or symptomatic CNS metastases. Patients with asymptomatic brain metastasis with no pending intervention needed, or patients with treated CNS disease and stable for at least 4 weeks and off anti-seizure medication and steroids for 7 days prior to initiation of LDC are eligible.
• Known hypersensitivity to one or more of the study agents.
• Comorbidities and any conditions, that in the opinion of the investigator, that put the subject at unacceptable risk for study therapy or prevent the participant from consenting or participating in the study.
• Uncontrolled or untreated infections, including but not limited to HIV, Hepatitis B or C infection.
• Uncontrolled angina, severe uncontrolled ventricular arrhythmias, or EKG suggestive of acute ischemia or active conduction system abnormalities.
• New progressive pulmonary infiltrates on screening chest CT scan that have not been evaluated with bronchoscopy. Infiltrates attributed to infection must be stable/ improving after 1 week of appropriate therapy (4 weeks for presumed or proven fungal infections).
• Received any investigational drugs within the 14 days prior to the first dose of fludarabine. (Wash-out period of at least 5 half-lives from the last dose of any investigational therapy prior to screening period or 14 days, whichever is longer).
• Pregnant or breastfeeding.
• Subjects are not acceptable candidates if they received prior tumor infiltrating lymphocytes (TIL) therapy (either in the setting of clinical trial or standard of care if TIL therapy is FDA approved in the future).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence and severity of adverse events	-As determined according to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI CTCAE v5.0)	From start of treatment through end of safety follow-up (estimated to be 15 months)
Secondary	Objective response rate (ORR)	Objective response rate (ORR), defined as the proportion of patients with a complete response (CR) or partial response (PR) on two consecutive occasions Objective response rate (ORR), defined as the proportion of patients with a complete response (CR) or partial response (PR) on two consecutive occasions = 4 weeks apart, according to RECIST v1.1. 4 weeks apart, according to RECIST v1.1.; Complete Response (CR). Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm (<1 cm).Disappearance of all non-target lesions and normalization of tumor marker level.; Partial Response (PR). At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.	Through completion of treatment (estimated to be 12 months)
Secondary	Duration of response (DOR)	-Duration of response (DoR), defined as the time from the first occurrence of a documented response after the ML NK cell infusion, to disease progression or death according to RECIST v1.1.	Through completion of follow-up (estimated to be 3 years)
Secondary	Progression-free survival (PFS)	PFS, defined as the time from ML NK cell infusion to the first occurrence of disease progression or death from any cause (whichever occurs first), according to RECIST v1.1.; Progressive Disease (PD). At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm (0.5 cm). Appearance of 1 or more new lesions and/or unequivocal progression of existing non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.	Through completion of follow-up (estimated to be 3 years)
Secondary	Disease control rate (DCR)	Disease control rate (DCR), defined as the percentage of patients who have achieved a complete response, partial response, or stable disease according to RECIST v1.1.; Complete Response (CR). Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm (<1 cm).Disappearance of all non-target lesions and normalization of tumor marker level.; Partial Response (PR). At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.; Stable Disease (SD). Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.	Through completion of follow-up (estimated to be 3 years)
Secondary	Overall survival (OS)	-OS, defined as the time from ML NK cell infusion to death from any cause.	Through completion of follow-up (estimated to be 3 years)
