Thymic Neuroendocrine Tumors clinical trials

Multicenter Phase II Study of IMC-A12 in Patients With Thymoma and Thymic Carcinoma Who Have Been Previously Treated With Chemotherapy

Background: - Cisplatin-containing chemotherapy is the standard of care for advanced thymoma and thymic carcinoma that cannot be treated with surgery. New options for treatment are necessary in patients with advanced thymoma and thymic carcinoma that have progressed on cisplatin-containing therapy. - IMC-A12 is a new (experimental) agent that has not yet been approved by the Food and Drug Administration. IMC-A12 blocks the Insulin-like Growth Factor 1 receptor (IGF-1R). IGF-1R is found on many types of cancer cells, including cancer of the thymus, and is thought to play an important role in helping these cells to grow and divide. Objectives: - To determine if IMC-A12 has an effect on tumor growth in patients with cancer of the thymus. - To evaluate the safety and tolerability of IMC-A12 in treatment for cancer of the thymus. Eligibility: - Individuals older than 18 years of age who have cancer of the thymus (thymoma, thymic carcinoma, or thymic carcinoid tumors) that has progressed in spite of standard treatment. Design: - Treatment will take place in 21-day cycles. Patients will receive one dose of IMC-A12 intravenously once every 3 weeks at the Clinical Center. During the Clinical Center visits, researchers will perform study tests and procedures to see how the study drugs are affecting the body. - Patients will undergo a number of tests and procedures during the treatment cycle, including physical examinations, blood and urine samples for standard tests, imaging studies (ultrasound, magnetic resonance imaging (MRI) or computed tomography (CT) scans) to evaluate tumor growth, and blood and urine samples to evaluate the amount of IMC-A12 in the body. - Patients may continue to take the drug as long as there are no adverse side effects and as long as the tumor does not grow.
