Uveal melanoma is the most common primary intraocular malignancy in adults and is considered an ultra-rare cancer,1 with approximately 2,500 patients diagnosed annually in the US.2 In approximately 50 percent of patients, ocular melanoma will spread to distant parts of the body within 15 years after treatment of the primary tumor1,3 with the liver the first site of metastasis in up to 90% of patients.3
TriSalus’ Approach to Studying a Treatment for Uveal Melanoma Liver Metastases
TriSalus’ clinical program for treatment of uveal melanoma liver metastases will initially evaluate our investigational TLR9 agonist, SD-101, delivered deep into the vasculature of the solid tumors using our proprietary, FDA cleared drug delivery technology. TLR9 agonists such as SD-101 are not administered intravenously but by direct injection into the skin or tumors, making treatment of liver metastases very difficult.
Our approach to the study will deliver SD-101 directly into the artery supplying the liver, with the potential to distribute the drug into uveal melanoma liver metastases, irrespective of size, number, and location of tumors within this organ.

Locally Advanced Pancreatic Ductal Adenocarcinoma (PDAC) and Liver Metastases
PDAC is the most common tumor arising in the pancreas, accounting for about 85-90% of cases.1 There are usually no symptoms in the disease’s early stages2 and by the time of diagnosis, pancreatic cancer has often grown beyond the limits of surgical therapy and/or to other parts of the body, including nearby lymph nodes, liver, peritoneal cavity, large intestine or lungs.3,4 Pancreatic adenocarcinoma typically has a very poor prognosis with a 5-year relative survival rate of 9% for all stages and 3% for advanced disease.5
TriSalus’ Dual Approach to Studying a Treatment for Locally Advanced PDAC and Liver Metastases
Studying Locally Advanced PDAC Treatment
Unlike the liver, the pancreas does not have a single artery feeding it, making regional intravascular delivery challenging.
TriSalus’ proprietary Pancreatic Retrograde Venous Infusion™ (PRVI™) technique using our PEDD™ with SmartValve™ technology to administer drug into the venous system allows the study for the delivery of investigational SD-101 directly into locally advanced tumors within the pancreas.
Studying PDAC Liver Metastases Treatment
TLR9 agonists such as SD-101 are not administered intravenously but by direct injection into the skin or tumors, making treatment of liver metastases very difficult.
Our approach will study the delivery of investigational agent, SD-101, directly into the artery supplying the liver with the goal to enable distribution of the drug into the PDAC liver metastases, irrespective of size, number, and location of tumors within this organ.

Colorectal Cancer Liver Metastases
Colorectal cancer (CRC) is the fourth most common major cancer in the United States, as approximately 1 in 25 people will be diagnosed with CRC during their lifetime.1,2 Overall, five-year survival rates have increased over time, largely due to increased screening procedures. Despite this, in 20% of cases, CRC has already metastasized at the time of diagnosis3 and represents a serious and life-threatening disease with a poor prognosis. Overall, nearly 70% of CRC metastases occur in the liver3 with the median survival for patients of about 9 months.3
TriSalus’ Approach to Studying CRC Liver Metastases
TLR9 agonists such as SD-101 are not administered intravenously but by direct injection into the skin or tumors, making treatment of liver metastases very difficult.
Our approach will study the delivery of investigational agent, SD-101 directly into the artery supplying the liver, the goal is to enable distribution of the drug into the CRC liver metastases, irrespective of size, number, and location of tumors within this organ.
