Trial Summary

What is the purpose of this trial?

The goal of this clinical trial is to study the effect of sacituzumab govitecan-hziy in adult patients with advanced thymoma and thymic carcinoma after progressing on at least one prior line of therapy. The main question it aims to answer is: • What is the overall response rate (ORR) in patients with advanced thymoma and thymic carcinoma? Participants will: * receive a fixed dose of 10 mg/kg given intravenously, once weekly on Days 1 and 8 of continuous 21-day treatment cycles until disease progression or unacceptable toxicity * have regular blood tests, scans, and examinations to monitor their health. * have blood and a biopsy of their tumor for research purposes.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but it does mention that you cannot have concurrent therapy with other approved or investigational anticancer treatments. It's best to discuss your current medications with the trial team to get a clear answer.

How is the drug Sacituzumab Govitecan unique for treating thymic cancer?

Sacituzumab Govitecan is unique because it is an antibody-drug conjugate, which means it combines an antibody that targets cancer cells with a chemotherapy drug, allowing for direct delivery of the chemotherapy to the cancer cells. This targeted approach may offer a novel treatment option for thymic cancer, which currently has limited effective therapies. ^{1 2 3 4 5}

Treatment Details

Interventions

• Sacituzumab Govitecan (Monoclonal Antibodies)

Trial Overview The trial tests Sacituzumab Govitecan's effectiveness in treating advanced thymoma and thymic carcinoma. The key measure is the overall response rate to this medication after previous treatments failed. Patients get fixed doses over continuous 21-day cycles until they can't tolerate it or their disease gets worse.

Findings from Research

In a multicenter phase II study involving 15 patients with metastatic thymic epithelial tumors, the combination of capecitabine and gemcitabine (CAP-GEM) demonstrated a promising objective response rate of 40%, with complete and partial responses observed in 20% of patients each.

The treatment was generally well-tolerated, with manageable side effects primarily including grade 1-2 neutropenia, anemia, and thrombocytopenia, and a median progression-free survival of 11 months, suggesting that CAP-GEM could be an effective option for pretreated TETs.

Sunitinib, a tyrosine kinase inhibitor, has been shown to be effective in a phase II trial for patients with thymic carcinoma who have already undergone previous treatments.

This study provides the first viable second-line treatment option for patients suffering from this rare and aggressive type of thymus cancer.

A multicenter phase II study is investigating the combination of atezolizumab (an anti-PD-L1 antibody) with carboplatin and paclitaxel in 47 patients with advanced or recurrent thymic carcinoma, aiming to improve treatment outcomes compared to standard chemotherapy.

The study will assess the safety and efficacy of this combination therapy, with the primary focus on the objective response rate, and will follow patients for up to 2 years to evaluate long-term effects.
