Squamous Cell Carcinoma of the Head and Neck
Conditions
Keywords
programmed cell death ligand 1 (PD-L1), MEDI4736, Cytotoxic T-lymphocyte-associated antigen 4 {CTLA-4}, PFS, SCCHN
Brief summary
This is a randomized, open-label, multi-center, 3-arm, global Phase III study to determine the efficacy and safety of MEDI4736 + tremelimumab combination or MEDI4736 monotherapy versus SoC (EXTREME regimen) in the treatment of patients with SCCHN who have not received prior systemic chemotherapy for recurrent or metastatic disease.
Detailed description
Patients will be randomized in a 2:1:1 ratio to MEDI4736 + tremelimumab combination therapy, MEDI4736 monotherapy, or SoC. Patients in all arms will continue therapy until progression. Tumor assessments will be performed on computed tomography scans or magnetic resonance imaging scans, preferably with intravenous (IV) contrast. Efficacy for all patients will be assessed by objective tumor assessments every 6 weeks for the first 24 weeks, then every 8 weeks thereafter until treatment discontinuation due to progression or toxicity. All patients will be followed every 3 months for survival after progression is confirmed.
