Combination of Nanoxel and Herzuma in Salivary Duct Carcinoma

Study Overview
=================
Brief Summary
-----------------
Study outline This is a multicenter, single-arm, phase II trial to evaluate the efficacy and safety of nanoxel plus herzuma combination chemotherapy in patients with metastatic salivary ductal cancer. Approximately 41 patients will be enrolled. Treatment will be continued until disease progression or unacceptable toxicities. Response evaluation will be performed every 2 cycles. Dosing & Treatment schedule D1 Nanoxel 75 mg/m2 + D5W 100mL MIV over 1hr D1 Herzuma 8mg/kg (loading dose) + N/S 250mL miv over 90mins 6mg/kg (maintenance) + N/S 250mL MIV over 30mins (since 2 cycle) repeated every 3 weeks (In case of discontinuation of nanoxel without progression, single agent herzuma can be administered until progression)
