Phase 1/2 Study of EB-NK-301 (Allogeneic TROP2-CAR NK Cells) in Advanced TROP2-Expressing Solid Tumors (SOLID-NK)
A Phase 1/2, Open-Label, Dose-Escalation and Dose-Expansion Study Evaluating the Safety, Tolerability, and Preliminary Anti-tumor Activity of EB-NK-301 (Allogeneic TROP2-Targeted CAR NK Cells) Following Lymphodepleting Chemotherapy in Adults With Advanced or Metastatic TROP2-Expressing Solid Tumors
study evaluates EB-NK-301, an investigational off-the-shelf allogeneic CAR-NK cell product targeting TROP2, in adults with advanced or metastatic solid tumors that express TROP2 and have progressed after standard therapy.
The primary goals are to assess safety and tolerability, identify dose-limiting toxicities (DLTs), and determine a recommended Phase 2 dose (RP2D). Secondary goals include preliminary anti-tumor activity, persistence of infused CAR-NK cells, and exploratory immune biomarkers.
연구 개요
상세 설명
Study Overview: The study includes two parts. Part A (dose escalation) uses a standard dose-escalation design to evaluate multiple dose levels of EB-NK-301 after lymphodepleting chemotherapy. Part B (dose expansion) enrolls additional participants at the selected RP2D to further characterize safety and to estimate preliminary efficacy within selected tumor-type cohorts.
Treatment Plan: Participants receive lymphodepleting chemotherapy (fludarabine and cyclophosphamide) followed by intravenous EB-NK-301 infusions. Participants are monitored closely for cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), infusion reactions, and other adverse events.
Assessments: Tumor imaging is performed every 8 weeks during the first 12 months, then every 12 weeks as clinically indicated. Blood samples are collected to assess CAR-NK cell persistence, cytokines, and other immune biomarkers.
Follow-up: Participants are followed for safety and survival for up to 24 months after first infusion.
