What is the mechanism of action of this treatment?

The most common treatments for melanoma, particularly advanced stages, include immune checkpoint inhibitors such as PD-1 inhibitors (e.g., nivolumab and pembrolizumab). These drugs work by blocking the programmed death-1 (PD-1) receptor on T-cells, preventing it from binding to its ligand PD-L1 on tumor cells. This blockade reactivates T-cells, allowing them to recognize and attack melanoma cells more effectively. This mechanism is crucial for melanoma patients as it enhances the body's immune response against cancer, potentially leading to better control of tumor growth and improved survival outcomes.

What side effects are associated with this type of intervention?

The most common treatments for melanoma, particularly those involving PD-1 inhibitors like nivolumab (OPDIVO®), can lead to a range of side effects. These include skin reactions (such as rash and pruritus), endocrine events (like thyroid dysfunction), and gastrointestinal issues (such as diarrhea). Immunotherapy with PD-1 inhibitors may also cause immune-related adverse events, including pneumonitis, hepatitis, and colitis. Combination therapies with CTLA-4 inhibitors (e.g., ipilimumab) can increase the frequency and severity of these side effects, leading to higher rates of serious adverse reactions such as pneumonia, febrile neutropenia, and acute kidney injury.

What prior FDA approvals exist?

The FDA has approved several PD-1 inhibitors for the treatment of melanoma. Nivolumab (Opdivo) and pembrolizumab (Keytruda) are prominent examples. Nivolumab is approved for use in patients with progression after chemotherapy, and pembrolizumab has been approved for various advanced solid tumors, including melanoma, based on its efficacy in improving progression-free survival and overall survival. These approvals are based on data from multiple clinical trials demonstrating their effectiveness in treating advanced melanoma.

What other types of research exist?

Promising novel alternatives to ABP 206 (PD-1 inhibition) for melanoma patients include: 1) CEACAM1 immune checkpoint inhibitors, which are in the development pipeline and show potential in disarming tumor escape mechanisms. 2) Combination therapies such as talimogene laherparepvec (T-VEC) plus pembrolizumab, which have shown efficacy in advanced melanoma. 3) CTLA-4 inhibitors like ipilimumab, either alone or in combination with PD-1 inhibitors, which continue to be a cornerstone in melanoma treatment.

Summary

This trial is testing a new drug, ABP 206, against an existing drug, OPDIVO® (nivolumab), in patients who have had surgery for advanced melanoma. The goal is to see if ABP 206 is as effective and safe as OPDIVO® in preventing the cancer from returning by helping the immune system fight cancer cells. Nivolumab, marketed as OPDIVO®, has been used in various treatments for melanoma, showing improved outcomes in patients with advanced melanoma.

Who is the study for?

This trial is for adults over 18 with advanced melanoma that's been surgically removed within the last 12 weeks. Participants should be relatively healthy, with a performance status showing they can carry out daily activities (ECOG score of 0 or 1). They must have tumor tissue available for testing and cannot have had previous cancer treatments, autoimmune diseases, severe allergies to monoclonal antibodies, ocular melanoma, or require systemic immunosuppression.

What is being tested?

The study is comparing ABP 206 to two versions of Nivolumab: one licensed in the US (FDA-licensed) and another authorized in Europe (EU-authorized). It aims to see if ABP 206 works similarly in terms of pharmacokinetics (how the drug moves through the body), effectiveness, safety profile, and whether it triggers immune responses against itself.

What are the potential side effects?

Potential side effects may include immune-related reactions such as inflammation in various organs like lungs or intestines; skin issues; hormonal gland problems; infusion reactions during administration; fatigue; and possibly other symptoms similar to those observed with Nivolumab.
