NCT05629546

Brief 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 allogeneic source will be used for Arm 2. The investigators hypothesize that ML NK cells from either an autologous source or allogeneic source are safe and tolerable in subjects with advanced and/or metastatic melanoma.

Study Arms (3)

Arm 1: Autologous: Memory-like natural killer cells + nivolumab + relatilimab

EXPERIMENTAL

* Subjects enrolled into arm 1 will receive autologous ML NK cells on Day 0. * Relatlimab and nivolumab will be initiated at day 29 and continue every 28 days for 11 cycles, or until unacceptable toxicity, or progression, whichever is earlier.

Biological: Cytokine-induced memory-like natural killer cellsBiological: RelatilmabBiological: Nivolumab

Arm 2: Allogeneic: Memory-like natural killer cells + nivolumab + relatilimab

EXPERIMENTAL

* Subjects with a haploidentical donor will enroll into Arm 2 * Subjects will receive the IV infusion of ML NK cells on Day 0. * Relatlimab and nivolumab will be initiated at day 29 and continue every 28 days for 11 cycles, or until unacceptable toxicity, or progression, whichever is earlier.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of histologically confirmed advanced or metastatic melanoma that has progressed after at least 12 weeks or a minimum of 2 doses of treatment with a standard of care PD1/PDL1 containing therapy (nivolumab, pembrolizumab, atezolizumab, or durvalumab).
  • Age: ≥18 years of age
  • Have an Eastern Cooperative Oncology Group Performance Status (ECOG) ≤ 2 at screening Form Arm 1 only: Patients must meet the eligibility criteria to undergo apheresis to obtain autlogous NK cells.
  • For Arm 2 only: Patient must have an available allogeneic NK cell donor who meets the eligibility criteria.
  • Adequate organ function as defined below:
  • Total bilirubin \< 2 mg/dL
  • AST(SGOT)/ALT(SGPT) \< 3.0 x ULN
  • Creatinine within normal institutional limits OR creatinine clearance \> 40 mL/min/1.73 m\^2 by Cockcroft-Gault Formula
  • 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.
  • 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.

  • 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.
