It is also testing an immune-stimulating drug, nelitolimod, given through those devices, in early trials.","summary":"TriSalus Life Sciences, headquartered in Westminster, Colorado, develops what it calls Pressure-Enabled Drug Delivery (PEDD): devices that modulate pressure and flow in blood vessels to overcome intratumoural pressure and improve delivery of therapies to liver and pancreatic tumours. It has two FDA-cleared devices, the TriNav Infusion System for delivery into the liver and the Pancreatic Retrograde Venous Infusion (PRVI) System, and says PEDD has been used in over 18,000 procedures. In 2020 it acquired nelitolimod (SD-101), an investigational TLR9 agonist, which it is testing delivered by PEDD with checkpoint inhibitors in phase 1 trials in uveal melanoma with liver metastases, hepatocellular carcinoma and intrahepatic cholangiocarcinoma, and locally advanced pancreatic adenocarcinoma (NCT04935229, NCT05220722, NCT05607953). Its common stock trades on Nasdaq as TLSI; SEC records show the listed company was formerly MedTech Acquisition Corp, renamed in August 2023.","asOf":"2026-11-04","links":[{"label":"Official website","url":"https://trisaluslifesci.com/"},{"label":"Pipeline","url":"https://trisaluslifesci.com/pipeline/"},{"label":"Drug delivery technology","url":"https://trisaluslifesci.com/drug-delivery-technology/"},{"label":"Nelitolimod","url":"https://trisaluslifesci.com/candidate-nelitolimod/"},{"label":"SEC EDGAR filings","url":"https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001826667"},{"label":"OrbiMed portfolio entry","url":"https://www.orbimed.com/portfolio/"}],"tags":[],"related":[],"cancers":["hcc","intrahepatic-cholangiocarcinoma","pancreatic","uveal-melanoma"],"sections":["surgery","immunotherapy"],"technologies":[],"targets":[],"drugs":["nelitolimod"],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Founding year not stated on the pages read.","OnCo has no TLR9 target record and no technology record for pressure-enabled intravascular delivery, so targets and technologies are empty.","None of the TriSalus-sponsored nelitolimod trials has an OnCo trial record.
