Scientific titleA Phase II study of pazopanib in metastatic merkel cell carcinoma
Study acronymUKMCC-01
Study objectivesMerkel cell carcinoma (MCC) is a rare neuroendocrine cancer of the skin with poor prognosis. The annual incidence is thought to be 0.6 per 100,000 of population, with approximately 400 cases per year in the UK. In this study we aim to determine if pazopanib is clinically active, as determined by response rate using the RECIST scoring, in advanced MCC and thus warrants further investigation in a phase III trial. Furthermore, through a translational sub-study, we aim to explore the biological features of MCC and relate these to clinical outcome in order to identify possible clinical biomarkers and therapeutic targets.

6. Toxicities from first line chemotherapy resolved to at least grade 1
7. Adequate end organ function
7.1. Renal function tests: serum creatinine ≤150 μmol/L. If serum creatinine is >150 μmol/L, calculated creatinine clearance must be ≥30 ml/min Urine Protein to Creatinine ratio (UPC) <1. If UPC ≥1, then a 24-hour protein must be assessed. Patients must have 24-hour protein value <1 g to be eligible. Alternatively, Albumin/Creatinine ratio may be measured (in accordance with institutional policy, same test to be used for study duration)

7.3. Haematology: Absolute Neutrophil Count (ANC) ≥1.5 X 109/L, Serum creatinine ≤150 μmol/L. If serum creatinine >150 μmol/L, calculated creatinine clearance must be ≥30 ml/min, Urine Protein to Creatinine ratio (UPC) <1. If UPC ≥1, then a 24-hour protein must be assessed. Patients must have 24hour protein value <1 g to be eligible
7.4. Liver function tests: Total serum bilirubin ≤1.5 X Upper Limit Normal (ULN), Alanine Aminotransferase or Aspartate Aminotransferase (in accordance with institutional policy, same test to be used for study duration) ≤2.5 X ULN (or ≤5 X ULN if liver metastases are present)
7.5. Haematology: Absolute Neutrophil Count (ANC) ≥1.5 X 109/L Haemoglobin ≥10 g/dL Platelets ≥100 X 10 to the power of 9/L
7.6. Coagulation test: International Normalized Ratio ≤1.2 X ULN, unless on therapeutic anticoagulation. For patients on therapeutic anticoagulation, INR should be stable and in target range
8. Able to give written informed consent
9. Women of childbearing potential, or men in a relationship with a woman of childbearing age, prepared to adopt adequate contraceptive measures if sexually active
10. Willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures
