简要总结
Nelitolimod is a classC toll-like receptor 9 (TLR9) agonist that binds to TLR9 receptors on myeloid-derived suppressor cells(MDSCs) and helps reshape the tumor microenvironment (TME) and promote antitumor immunity. Investigators hypothesize that Nelitolimod can induce antitumor immune response in CRLM when administered regionally to the liver via a TriNav Pressure Enabled Drug Delivery (PEDD) catheter without compromising surgical feasibility or patient safety.
The study objective is to investigate the feasibility and safety of an innovative immunotherapeutic approach for patients with CRLM designed to overcome the immunosuppressive TME in CRLM. Investigators hypothesize that this investigational neoadjuvant treatment will be well tolerated and will not prevent patients from undergoing successful, safe CRLM liver resections. Investigators will assess the safety and feasibility of Nelitolimod given via TriNav PEDD in 10 patients with CRLM prior to liver resection. Patients will receive standard treatment with chemotherapy and then undergo placement of the PEDD catheter. Patients will then receive 3 doses of Nelitolimod before undergoing liver resection.

- •Hemoglobin ≥ 8 g/dL
- •Blood chemistry levels defined as:
- •AST, ALT, alkaline phosphatase ≤5 times upper limit of normal (ULN)
- •Total bilirubin ≤2x the ULN. Patients with Gilbert Syndrome should have a serum bilirubin ≤ 4x ULN and a direct bilirubin ≤2x ULN to be eligible.
- •Adequate renal function as estimated by glomerular filtration rate (eGFR) >30 L/min determined based on the Cockcroft-Gault formula.
- •Anticipated life expectancy greater than 6 months.
- •Women of childbearing potential (WOCB) receiving systemic therapy should use effective contraception during treatment and for at least 9 months after the last investigational agent. Patients with partners who could become pregnant should use effective contraception during treatment and for 6 months after the last dose of investigational agent.
