TriSalus Life Sciences to Showcase Treatment Platform and Present Pressure-Enabled Regional Immuno-Oncology (PERIO) Data at the Society of Interventional Radiology’s 2023 Annual Scientific Meeting

Feb 28, 2023


PHOENIX, February 28, 2023 – TriSalus Life Sciences® Inc., (“TriSalus” or the “company”), an oncology company integrating immunotherapy with disruptive delivery technology to transform the treatment paradigm for patients with liver and pancreatic tumors, will participate in a series of events at the Society of Interventional Radiology (SIR) 2023 Annual Scientific Meeting, held March 4-9, 2023, at the Phoenix Convention Center.

At this year’s conference, new data from Phase 1/1b of the company’s Pressure-Enabled Regional Immuno-Oncology (PERIO) clinical trial program will be presented. The PERIO-01 and PERIO-02 trials are studying an investigational toll-like receptor 9 agonist, SD-101, delivered intravascularly by the TriNav® Infusion System (“TriNav®”) using the company’s proprietary Pressure-Enabled Drug Delivery™ (PEDD™) method of administration. The studies are evaluating whether this platform approach can improve the performance of systemic checkpoint inhibitors in treating patients with uveal melanoma with liver metastases, hepatocellular carcinoma or intrahepatic cholangiocarcinoma.

In addition to several data presentations, the company is hosting numerous educational opportunities for interventional radiologists to learn more about the company’s FDA-cleared TriNav® Infusion System, including multiple in-booth presentations, a lunch symposium and an evening networking reception. The TriNav® Infusion System utilizes the PEDD™ method of administration with SmartValve™ technology to overcome intratumoral pressure and improve delivery of therapeutic agents during outpatient interventional radiology procedures.

The details of these additional activities are highlighted below. Oral abstract presentations listed below are part of the SIR 2023 CME-accredited scientific program and are not TriSalus-sponsored activities.

About TriSalus
TriSalus is an oncology company integrating immunotherapy with disruptive delivery technology to transform the treatment paradigm for patients with liver and pancreatic tumors. TriSalus’ proprietary platform approach addresses immune dysfunction in liver and pancreatic tumors by combining its highly effective drug delivery technology with immunotherapeutics. The TriSalus platform comprises the TriNav® Infusion System and SD-101, a class C toll-like receptor 9 (“TLR9”) agonist. TriNav® is an FDA-cleared device that is designed to administer established and emerging therapeutics. SD-101, the company’s investigational TLR9 agonist, is being delivered via TriNav® to selected sites, including tumors in the liver. TriNav® is the latest TriSalus asset for the proprietary PEDD™ method of administration which has been shown to overcome intratumoral pressure through modulation of pressure and flow to increase delivery of therapeutic agents.
