TriSalus Life Sciences Announces Publication of Safety and Efficacy Results for a Novel Pressure-Enabled Thyroid Embolization Technique
Published in the
“We are encouraged to see our technology being evaluated in new areas of clinical need,” said
Key Study Highlights:
- Population: 22 patients with symptomatic thyroid disease (benign thyroid nodules or multinodular goiters) (median age: 59)
- Procedure: Pressure-enabled embolization via the inferior thyroid artery; 45% had unilateral treatment and 55% bilateral
-
Outcomes:
- 100% technical and clinical success (technical success defined as successful catheterization and embolization. Clinical success measured as the absence of non-target embolization, target volume reduction, and/or normalization of thyroid function, when appropriate.)
- 71% (5 of 7) of patients with hyperthyroidism achieved normal thyroid function (euthyroid)
- 73% mean reduction in thyroid gland volume at 6 months (n=18)
- No major complications or neurovascular events
- Mild post-procedure symptoms (e.g., neck discomfort) reported in 81% of patients, resolving within two weeks
- No patients developed hypothyroidism following the procedure
The authors conclude that PED-TAE is a safe and feasible treatment option for large goiters and may offer an alternative to more invasive approaches for treating large benign thyroid nodules and benign multinodular goiters. However, prospective research is needed to establish long-term efficacy.
Additionally, a multi-institutional registry study (PROTECT, NCT06868459) has been initiated by
“These early results lay the foundation for a broader evaluation of pressure-enabled embolization in the management of benign thyroid disease,” said
“TriSalus continues to support innovations in embolization techniques,” said CEO
About
TriSalus Life Sciences® is an oncology focused medical technology company seeking to transform outcomes for patients with solid tumors by integrating its innovative delivery technology with standard-of-care therapies. The Company’s platform includes devices that utilize a proprietary drug delivery technology and a clinical stage investigational immunotherapy, nelitolimod, a class C Toll-like receptor 9 agonist, for a range of different therapeutic and technology applications. The Company’s two FDA-cleared devices use its proprietary Pressure-Enabled Drug Delivery™ (PEDD) approach to deliver a range of therapeutics: the TriNav® Infusion System for hepatic arterial infusion of liver tumors and the Pancreatic Retrograde Venous Infusion System for pancreatic tumors. The PEDD technology is a novel delivery approach designed to address the anatomic limitations of arterial infusion for the pancreas. The PEDD approach modulates pressure and flow in a manner that delivers more therapeutic to the tumor and is designed to reduce undesired delivery to normal tissue, bringing the potential to improve patient outcomes. Nelitolimod, the Company’s investigational immunotherapeutic candidate, is designed to treat the immunosuppressive environment created by many tumors and which can make current immunotherapies ineffective in the liver and pancreas. The Company is in the final stages of data completion for a number of phase 1 clinical trials and will begin exploring partnership opportunities for development. In partnership with leading cancer centers across the country – and by leveraging deep immuno-oncology expertise and inventive technology development – TriSalus is committed to advancing innovation that improves outcomes for patients.
