Correct answer: D — Pembrolizumab monotherapy with uninterrupted treatment capped at 2 years
TA661 recommends pembrolizumab only as monotherapy for untreated metastatic or unresectable recurrent HNSCC with CPS at least 1, with a 2-year uninterrupted-treatment cap. Although pembrolizumab plus chemotherapy is licensed and trial-supported, it is not the TA661 recommendation. Nivolumab is not the relevant untreated-disease appraisal, and the NICE threshold is CPS 1 rather than 20.
