An advanced way to treat hepatocellular carcinoma
(HCC) and liver metastases.
Intratumoral pressure (ITP) significantly impacts therapeutic delivery.3,4
Effective tumor penetration and saturation may not be achieved with standard approaches.1
Modulate intravascular pressure
to enable deeper perfusion.1
PEDD: A proprietary approach powered by SmartValve™ technology that works in sync with the heart6 to enhance delivery pressure beyond what the cardiovascular system can generate on its own,7 which may help to open collapsed vessels in the tumor and enable deeper perfusion.1,8
SmartValve: A one-way, intermittently occlusive valve that physiologically and atraumatically increases local vascular pressure at the target location7 to improve therapeutic delivery1 while helping to spare normal tissue.
The 5-year survival rate for HCC remains
poor at ~18% due to multiple factors.9
Difficult therapy delivery
Intra-tumoral pressure impacts the uptake of therapy in solid tumors.4,10
Limited therapy options
With systemic chemotherapy, it is difficult to achieve therapeutic levels within the tumor.11 Not only that, but concentrations of drug can accumulate in healthy tissue, which may lead to severe side effects and dose-limiting toxicity.11
Most patients are ineligible for curative treatments
Only 15% of patients are eligible for surgical resection or liver transplant.12
Slowing progression and improving tumor response can help more patients qualify for curative transplant.13
Patients with HCC or liver metastases can face dire outcomes. When transplant is an option, locoregional therapy (LRT) can help downstage ineligible patients to meet transplant criteria and bridge eligible patients through the waiting period,13 which is also recommended by clinical guidelines as an option.14
85% of HCC patients are ineligible for surgical resection or liver transplant.12
Liver transplantation for HCC provides a patient with the best chance at OS, with results of 60%-70% survival achieved at 5 years.15,16
Wait times for a liver transplant can range from <30 days to 5 years or more.17
Achieving complete response (CR) in HCC may extend
overall survival (OS).18
Findings from a US multicenter HCC Transplant Consortium showed that patients who achieved CR to LRT had better 1-, 3-, and 5-year OS and recurrence rates post-transplant.18
Recurrence and Survival Outcomes at 1, 3, and 5 Years After Liver Transplantation18
A database consisting of 20 transplant centers was retrospectively used to compare patients receiving pre-liver transplantation LRT with CR (n = 802) and without CR (n = 2637) from 2002 to 2013.18
Patients who achieve CR in fewer TACE treatments also have superior OS.19
TriNav, powered by the PEDD approach, has been shown in prospective and retrospective clinical studies and in multiple pre-clinical models to improve therapy uptake and tumor response.1,2,8,20,21
