EBNK-001 + IL-15 + Pembrolizumab
What this trial is about
This Phase 1/2 study evaluates the safety, tolerability, and preliminary anti-tumor activity of EBNK-001 (allogeneic NK cells) given after lymphodepleting cyclophosphamide/fludarabine (CY/FLU) and supported with low-dose IL-15, administered either alone or in combination with pembrolizumab in adults with advanced/metastatic solid tumors. The study will determine a recommended Phase 2 dose (RP2D) and explore signals of clinical activity using RECIST-based response criteria.

Inclusion criteria
- Age ≥18 years.
- Histologically confirmed advanced/metastatic solid tumor that is relapsed/refractory after standard therapy (or no standard therapy available).
- Measurable disease per RECIST v1.1 (or iRECIST if applicable).
- ECOG performance status 0-1 (or 0-2 as allowed).
- Adequate organ function (thresholds modeled on NK protocols):
- Platelets ≥ 75,000/µL; hemoglobin ≥ 9 g/dL; ANC ≥ 1,000/µL (unsupported by growth factors/transfusions as defined).
- eGFR ≥ 60 mL/min/1.73m².
- AST/ALT ≤ 3× ULN.
- Oxygen saturation ≥ 90% on room air (with PFT requirements if indicated).
- LVEF ≥ 40% (by ECHO/MUGA/CMR).
- If brain metastases are present, they must be stable for a defined period (example: ≥3 months) and not requiring escalating steroids.
Exclusion criteria
- Pregnant or breastfeeding.
- Any condition requiring systemic immunosuppression (e.g., \>5 mg prednisone/day or equivalent) during dosing window (topical/inhaled may be allowed).
- Active autoimmune disease requiring systemic immunosuppression.
- Uncontrolled bacterial, fungal, or viral infection.
- Receipt of investigational agent within 28 days before first study drug.
- Live vaccine within 6 weeks prior to lymphodepletion.
- Known HIV positivity or active hepatitis B/C with detectable viral load (protocol may allow chronic asymptomatic hepatitis depending on risk plan).
- Known allergy to investigational product components (example: albumin/human or DMSO).
- Any medical/social condition likely to interfere with study compliance or increase risk.
