About this trial
This phase II trial tests how well ivonescimab works in treating patients with thymic carcinoma. Immunotherapy with monoclonal antibodies, such as ivonescimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Cytologically or histologically confirmed thymic carcinoma, which is incurable
Received prior systemic therapy for thymic carcinoma, or is ineligible for or refuses other therapies
Measurable disease, as per RECIST 1.1
Disqualifiers
Prior treatment with an immune checkpoint inhibitor targeted PD-1 or PD-L1. Prior treatment with VEGF inhibitor is allowed
Concurrent enrollment in another clinical study, unless enrolled only in the follow-up period or an observational study
Any chemotherapy, immunotherapy, biologic, or hormonal therapy for cancer treatment in the prior 3 weeks or within 5 half-lives of the medication, whichever is shorter. Concurrent use of hormones for non-cancer-related conditions (eg, insulin for diabetes and hormone replacement therapy) is acceptable

Trial outcomes
Primary outcomes
Overall response rate (ORR)
ORR is defined as complete response or partial response by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. The ORR estimate and its associated 95% confidence interval will be calculated.
Secondary outcomes
Progression free survival
Cancer progression will be determined per RECIST 1.1.
