Brief Summary:
This study aims to investigate the clinical activity of sunitinib in patients with advanced thymic carcinoma who have failed chemotherapy.

Condition or disease Intervention/treatment Phase
Thymic Carcinoma Drug: Sunitinib Phase 2

Detailed Description:

Sunitinib (Sutent®; Pfizer, New York, NY, USA) is a multitargeted tyrosine-kinase inhibitor (TKI) with activity against the stem cell-factor receptor (KIT) and platelet-derived growth-factor receptor (PDGFR), vascular endothelial growth-factor receptor (VEGFR), glial cell line-derived neurotrophic factor receptor (rearranged during transfection [RET]), colony-stimulating factor-1 receptor (CSF1R), and Fms-like tyrosine kinase-3 receptor (FLT3).

Sunitinib is a potent inhibitor of mutant KIT with additional inhibitory effects on VEGF receptors that potentially might make it more effective than imatinib against TCs. In the current version of NCCN guideline, sunitinib is suggested as one of the potential targeted therapeutics for advanced TCs.

We planned this study to investigate the clinical efficacy and tolerability of sunitinib in patients with advanced or recurrent TCs in Korean population. In addition, we will collect tumor samples and blood samples from patients for the further exploration of predictive biomarkers.

Experimental: Sunitinib
Sunitinib will be administered orally at a dose of 50 mg once daily in 3-week cycles consisting of 2 weeks of treatment followed by 1 week without treatment.
Drug: Sunitinib

Primary Outcome Measures :
  1. Objective response rate [ Time Frame: Up to 6 months ]
    CR or PR by RECIST criteria version 1.1

Secondary Outcome Measures :
  1. Disease control rate [ Time Frame: Up to 6 months ]
    CR or PR or SD by RECIST criteria version 1.1

  2. Progression-Free Survival [ Time Frame: Up to 6 months ]
  3. Overall survival [ Time Frame: From first day of study treatment to day of any kind of death, assessed up to 24 months ]
  4. Incidence of treatment related adverse events [Safety and Tolerability] [ Time Frame: Up to 6 months ]
    Number of patients with adverse events during cycle 1 (each cycle is 21 days). Subjects will be evaluated for toxicity according to NCI-CTCAE(Common Terminology Criteria for Adverse Events) of version 4.0.

Other Outcome Measures:
  1. Biomarker endpoint [ Time Frame: Day 1 ]
    When available, banked tumor tissue for genomic analysis for predictive biomarker of sunitinib.

  7. Female patients who are pregnant, breast-feeding or male or female patients of reproductive potential who are not employing an effective method of birth control
  8. Other severe acute or chronic medical condition or laboratory abnormality that may increase the risk associated with trial participation or investigational product administration or may interfere with the interpretation of trial results and, in the judgment of the investigator, would make the patient inappropriate for entry into this trial. (including active bleeding, untreated DVT or thromboembolism)
