If you, or someone you know has metastatic uveal melanoma and is 18 years of age or older, you may want to learn more about the PERIO-01 clinical trial. Talk to your doctor about participating.
The Pressure-Enabled Regional Immuno-Oncology (PERIO-01) clinical trial will study a new investigational drug, SD-101, delivered intravascularly by the TriNav® Infusion System using the Pressure-Enabled Drug Delivery™ (PEDD™) method of administration. The study will evaluate if this platform approach can improve the performance of systemic checkpoint inhibitors in treating patients with liver metastases.
- high intratumoral pressure (ITP)
Studying a Platform Designed
to Address both Treatment Challenges
CHALLENGE 1: Immunosuppression
How do the liver's natural processes interfere with immunotherapy?
Part of a healthy liver's function is controlling immune response.
It's the way the liver manages inflammation and maintains homeostasis.
What happens when tumor cells are present in the liver?
When tumor cells are present in the liver, they trick the immune system by turning anti-tumor mechanisms off.1
The large number of myeloid derived suppressor cells (MDSCs) in the liver create a highly immunosuppressive tumor microenvironment (TME), which is an obstacle to traditional treatment or immunotherapy.
What is the significance of MDSCs in the liver?
MDSCs are key drivers of immunosuppression in the liver and pancreas and accelerate growth of other suppressor cell types2-4
High MDSC levels may predict poor outcomes in cancer patients5
How does investigational SD-101 address the immunosuppressive barrier?
- May stimulate an immune response that reduces and reprograms MDSCs.6,7
- Has been shown in preclinical data to improve the ability of the immune system to attack the cancer and respond to certain therapies.8
Why is this approach being combined with a checkpoint inhibitor?
Our immune system protects us from disease, killing bacteria and viruses. It also helps fight cancer. A T cell is one type of immune cell that does this.
Proteins on T cells turn the immune system on when it needs to fight. Other proteins — checkpoint molecules — turn the system off when not needed.
Cancer can trick the immune system by turning T cells off where they're most needed. Checkpoint inhibitors (CPIs) have shown promise in turning T cells back on so they recognize and attack the disease. We are studying SD-101 to determine if it can boost the effectiveness of CPIs in liver tumors so that T cells can identify and attack the uveal melanoma cancer cells.
CHALLENGE 2: High Intratumoral Pressure (ITP)
How does tumor growth impact treatment?
As the tumor grows, the pressure inside of it increases.9 This intratumoral pressure (ITP) causes blood vessels in the area to collapse, reducing blood flow.9
The lack of blood flow, the high ITP, and the dense tumor tissue create a physical barrier to drug delivery.10
In some cases, <1% of therapy has been reported to reach the tumor with standard delivery approaches.11,12
What is PEDD™?
PEDD stands for Pressure-Enabled Drug Delivery.
PEDD is designed to overcome the physical barrier / high ITP challenge so that more of the drug is delivered directly to the tumor.13,14
In this study, PEDD will enable SD-101 to be delivered into the arteries that supply the liver.
Am I eligible to participate
in this clinical trial?
You may qualify to participate in the study if you:
Are >18 years old
Have a confirmed diagnosis of metastatic uveal melanoma with liver-only or liver dominant disease
Have not received prior cytotoxic chemotherapy, targeted therapy, or external radiation therapy within 14 days prior to screening
Have no prior history of or other concurrent malignancy unless the malignancy is clinically insignificant, no ongoing treatment is required
Are clinically stable
Are not pregnant/breastfeeding
Have not had bacterial pneumonia within 8 weeks of first dose of study drug
Do not have active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection
Do not have active coronavirus disease 2019 (COVID-19), other severe infection, including a liver infection, within 2 weeks before the first dose of study drug, or uncontrolled human immunodeficiency virus (HIV) infection at screening
Do not have active, known, or suspected autoimmune disease or immune-mediated disease. Type 1 diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis or alopecia) not requiring systemic treatment or conditions not expected to recur in the absence of an external trigger are not exclusionary.

Why should I participate
in a clinical trial?
Virtually every therapy and many medical advancements have been made possible by individuals who take part in clinical trials. Clinical trials are needed for the development of new treatment options for people living with metastatic uveal melanoma and other diseases.
Others are here to support you in the fight against metastatic uveal melanoma.
