TriSalus Life Sciences is an oncology-focused medtech company combining proprietary drug-delivery devices with an investigational immunotherapy, nelitolimod, to treat solid tumors, especially in the liver and pancreas. Its core Pressure-Enabled Drug Delivery (PEDD) platform underpins the FDA‑cleared TriNav Infusion System and a 510(k)‑cleared pancreatic device (PRVI).
TriNav, used mainly in TACE and TARE procedures, has been employed in over 31,000 procedures and generated $45.2 million in 2025 revenue, a 53.4% increase versus the prior year. Clinical and real‑world data show improved tumor targeting, higher drug deposition and reduced complications compared with standard microcatheters. Management estimates a U.S. total addressable PEDD market projected to exceed $2.3 billion annually across liver cancers, pancreatic tumors, fibroids, multinodular goiters, prostate disease and osteoarthritis‑related knee pain.
Nelitolimod, a class C TLR9 agonist acquired from Dynavax, is being tested with PEDD in three Phase 1 PERIO studies in uveal melanoma liver metastases, cholangiocarcinoma, hepatocellular carcinoma and locally advanced pancreatic cancer, with readouts expected in 2026. The company holds a broad patent portfolio extending into the 2030s, manufactures TriNav in Colorado, and benefits from permanent CMS reimbursement codes C9797 and C8004 that support outpatient and ambulatory use.
TriSalus Life Sciences reported strong growth for 2025 but remained unprofitable. Revenue from the TriNav system reached $45.2 million for the year, up 53% from 2024, with fourth quarter revenue of $13.2 million, a 60% year-over-year increase and 14% sequential growth.
Full-year gross profit rose to $38.2 million, though gross margin edged down to 84.6%, reflecting launch-related manufacturing inefficiencies. Operating loss narrowed to $26.9 million, and adjusted EBITDA loss improved to $17.2 million. Net loss attributable to common stockholders expanded to $69.7 million, mainly due to preferred stock conversion-related items.
Cash and cash equivalents were $20.4 million as of December 31, 2025, and subsequent to year-end the company raised $46 million in gross proceeds via a public offering. Management reaffirmed 2026 revenue guidance of $60–62 million and highlighted continued commercial adoption of TriNav, higher gross margins in Q4 2025, and ongoing investments in clinical studies and new PEDD-based products.
