Awards & highlights


This trial is testing a new vaccine combo to treat melanoma, with the goal of making it safe & effective.

Who is the study for?
This trial is for adults with untreated, unresectable stage III or IV melanoma. Participants must have good performance status, adequate organ function, and no prior systemic therapy against their melanoma in the last 6 months. They should not have brain metastases or a history of severe allergies to study drugs. Contraception is required for those who can bear children.Check my eligibility
What is being tested?
The study tests if IO102/IO103 vaccines combined with nivolumab and relatlimab are safe and effective for advanced melanoma treatment. It's designed to see how well this combination works compared to standard treatments.See study design
What are the potential side effects?
Potential side effects may include typical reactions from immunotherapy such as fatigue, skin reactions, inflammation in organs like the liver or lungs, flu-like symptoms from the vaccine component, and possible allergic reactions.

Group I: IO102/IO103, Nivolumab, and RelatlimabExperimental Treatment2 Interventions
All patients will be treated with nivolumab-relatlimab FDC on Day 1 of every 28-day cycle for up to two years. Patients will be treated with IO102/IO103 on Days 1 and 15 of the first two 28-day cycles, then on Day 1 of subsequent cycles for up to two total years of treatment.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
The most common treatments for melanoma, such as Nivolumab and Relatlimab, work by enhancing the body's immune response against cancer cells. Nivolumab is a PD-1 inhibitor that prevents cancer cells from evading immune detection, while Relatlimab is a LAG-3 inhibitor that further boosts immune activity. The study vaccines IO102/IO103 aim to stimulate the immune system to recognize and attack melanoma cells. This combination is significant for melanoma patients as it potentially offers a more robust and effective immune response, improving the chances of controlling and eliminating the cancer.
