What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests INBRX-109, a protein that attaches to harmful cells and signals the body to destroy them. It targets patients with conditions involving DR5, like certain cancers.

Will I have to stop taking my current medications?

The trial requires that you have not received any anticancer therapy within 4 weeks or within 5 half-lives prior to the first dose of the study treatment. This suggests you may need to stop certain medications before participating, but the protocol does not specify all medications.

Are You a Good Fit for This Trial?

This trial is for adults with advanced or inoperable solid tumors, including various sarcomas and specific cancers like mesothelioma and pancreatic adenocarcinoma. Participants must have tried standard treatments without success or have no beneficial standard options available. They should be physically able to perform daily activities (with some limitations) and have their major organs functioning well. People with recent severe liver disease, infections needing antibiotics, prior DR5 agonist exposure, other cancer treatments within the last month, certain heart conditions, or known sensitivity to the study drugs cannot join.

Inclusion Criteria

My cancer is advanced, cannot be surgically removed, and does not respond to standard treatments.
I am between 12 and 84 years old with Ewing sarcoma, or 18 and 84 with GIST.
My blood, liver, and kidney functions meet the required health standards.

What Are the Treatments Tested in This Trial?

Interventions

  • INBRX-109
Trial Overview The trial is testing INBRX-109, a new antibody targeting death receptor 5 on cancer cells. It's given alongside existing chemotherapy drugs: carboplatin, cisplatin, pemetrexed, fluorouracil (5-FU), irinotecan, and temozolomide. The study has three parts but isn't randomizing patients; instead it progressively includes more participants as safety data emerges.
