Interventions

  • Durvalumab Plus Tremelimumab — DRUG
    Durvalumab 1500mg plus tremelimumab 75mg via IV infusion Q4W, starting on Week 0, for up to a maximum of 4 doses/cycles followed by durvalumab monotherapy 1500mg via IV infusion Q4W, starting 4 weeks after the last infusion of the combination until progression.).

Study Details

* Clinical Phase: phase II single arm study * Primary Objectives: Response rate * Number of Subjects: 27 patients * Study Population: recurrent or metastatic head and neck squamous cell carcinoma * Investigational Product(s), Dose, and Mode of Administration: Durvalumab 1500mg plus tremelimumab 75mg via IV infusion Q4W, starting on Week 0, for up to a maximum of 4 doses/cycles followed by durvalumab monotherapy 1500mg via IV infusion Q4W, starting 4 weeks after the last infusion of the combination until progression.). Proton therapy 5 GyE x 5 fractions \- Study Assessments and Criteria for Evaluation: Safety Assessments: according to NCI CTCAE version 4.0 Efficacy Assessments: according to RECIST version 1.1 \- Statistical Methods and Data Analysis: PFS: from the date of treatment to the date of progression or death or last follow-up OS: from the date of treatment to the date of death or last follow-up \- Sample Size Determination: Patients must have a histologically confirmed diagnosis of HNSCC. In this phase II study, up to approximately 27 eligible patients will be enrolled. It is anticipated that full accrual to this study will take approximately 24 months. H0: Objective response rate ≤10% H1: Objective response rate ≥35% According to Simon's two-stage optimal design (power of 90% and one-sided alpha of 0.05), this study needs total 27 evaluable patients. At the first stage, 11 patients would be enrolled. If two or more among them achieve objective response, the study will go forward the second stage. At the second stage, 16 additional patients (total 27 patients) would be enrolled. Among the total 27 evaluable patients, six or more objective responses are necessary for this drug to be evaluated further in the group of R/M HNSCC
