What You Need to Know Before You Apply

What is the purpose of this trial?

This is a multicenter, open-label, phase I/II basket study, evaluating the safety, tolerability, RP2D, pharmacokinetics, pharmacodynamics and antitumor activity of EOS-448 (also known as GSK4428859A or belrestotug) combined with standard of care and/or with investigational therapies in participants with advanced solid tumors.

Will I have to stop taking my current medications?

The trial requires that you have not received any anti-cancer therapy within 4 weeks before the first dose, so you may need to stop certain cancer treatments. However, the protocol does not specify about other medications, so it's best to discuss with the trial team.

Are You a Good Fit for This Trial?

This trial is for adults with advanced solid tumors, including melanoma, lung cancer, and head & neck cancers. Participants must have progressed on anti-PD-(L)1 therapy (for melanoma), or be eligible for first-line metastatic treatment combining anti-PD(L)1 therapy with chemotherapy. They should not have received recent anticancer therapies or live vaccines, nor should they have uncontrolled diseases or certain genetic aberrations indicating other treatments.

Inclusion Criteria

My head and neck cancer cannot be cured with surgery or radiation.

My cancer is advanced or has spread, and there are no standard treatments left.

Part 2 (H&N cancer): PD-L1 status positive

Exclusion Criteria

My brain metastases have been treated and stable for over a month.

I have not received a live vaccine in the last 30 days.

I have been diagnosed with a primary brain cancer.

What Are the Treatments Tested in This Trial?

Interventions

• Dostarlimab
• EOS-448
• inupadenant
• Pembrolizumab
• SOC chemotherapies

Trial Overview The study tests EOS-448 combined with standard care and/or investigational drugs in patients with advanced tumors. It's an open-label phase I/II trial to assess safety, dosage, how the body processes the drug (pharmacokinetics), its effects on the body (pharmacodynamics), and its ability to fight tumors.
