Plain-language summary
Nasopharyngeal carcinoma (NPC) is an endemic malignancy in Southern China and southeast Asia. Despite intensive radical therapy, between 15% and 30% of NPC patients develop relapse. Recent phase III randomized-controlled trials conducted in China demonstrated an improvement of progression-free survival with combinational therapy immune checkpoint inhibitors (ICI) (camrelizumab, toripalimab, and tislelizumab, respective) and chemotherapy gemcitabine (G) and cisplatin (P) compared with chemotherapy GP alone for recurrent or metastatic NPC. However, none of these studies have described in details the treatment outcomes of those subjects with locally recurrent NPC only, and whether any of these patients would undergo radical surgery to remove the residual locally recurrent NPC after ICI and chemotherapy. Continuation of the same ICI as maintenance therapy may only be the treatment option for these patients who were recruited into these phase III trials, unless if they withdrew from the study and opted for radical resection. While continuing the same ICI may still lead to persistent objective response and disease control, there is a possibility of tumor recurrence leading to unresectable disease and a worse survival outcome, or unexpected, rare but recognized immune-related emergent adverse events with ICI. Radical resection after maximal response to ICI and chemotherapy for patients with locally recurrent NPC only may provide a chance of cure of the disease and these patients may be obviated from continuous exposure to ICI therapy.
In view of the above, we are now proposing a phase II single-arm study on perioperative pembrolizumab and chemotherapy followed by radical surgery for locally recurrent NPC. As a collateral study, we will also perform single-cell DNA and RNA sequencing and proteomics study to observe the tumor and immune microenvironment which certainly helps us decipher the mechanisms of tumor response at genomic, transcriptomic and proteomic levels.

Inclusion criteria
✓. Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of histologically confirmed locally recurrent (rT2-T4, N0-N1, M0) NPC (undifferentiated carcinoma with Epstein-Barr virus (EBV) infection by either presence of Epstein-Barr virus encoded RNA (EBER) in in-situ hybridization of the recently obtained tumor specimen before study entry) or an elevation of plasma EBV DNA in the subject's peripheral blood), staged according to the 8th edition of American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) staging classification (TNM-8). All patients should NOT have received any form of anti-tumor treatment for their locally recurrent NPC before joining the study. However, prior radical treatment for their NPC at diagnosis is allowed if there is at least a 6-month interval between prior radical treatment and the start of study intervention of this study.
✓. The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.
✓. Aged ≥18 years old
✓. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. Evaluation of ECOG is to be performed within 7 days prior to the first dose of study intervention.
✓. All eligible patients must be magnetic resonance imaging of T1, T2 and T1-contrast enhanced sequences of the head and neck region and PET-CT scan within 30 days of study entry.
✓. Adult Comorbidity Evaluation (ACE)-27 Index \<2
✓. Pre-existing peripheral neuropathy \<=1
Exclusion criteria
✕. Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of treatment or 5 half-lives, whichever is shorter.
✕. Has a diagnosis of severe active scleroderma, lupus, other rheumatologic or autoimmune disease within the past 3 months before study recruitment. Patients with a documented history of clinically severe autoimmune disease or a syndrome requiring systemic steroids or immunosuppressive agents will not be allowed on this study. Subjects with vitiligo or resolved childhood asthma/atopy are an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections are not excluded from the study. Subjects with hypothyroidism stable on hormone replacement are not excluded from this study.
✕. Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
✕. Has had any prior monoclonal antibody before study entry, including but not limited to anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another costimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137 etc).
✕. Has had prior chemotherapy or targeted small molecule therapy (including sorafenib or other anti-vascular endothelial growth factor inhibitor) before study entry. Patients who received radical radiation therapy and chemotherapy (but not immune checkpoint inhibitors or any form of immunotherapy) for their previously untreated nasopharyngeal carcinoma at diagnosis was allowed to join this study, provided that such radical treatment was completed \>6 months before study entry.
✕. Has a known additional malignancy that is progressing or has required active treatment within the past 2 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin or carcinoma in situ, excluding carcinoma in situ of the bladder, that have undergone potentially curative therapy are not excluded. Other exceptions may be considered with Sponsor consultation.
✕. Has known carcinomatous meningitis (also known as leptomeningeal carcinomatosis).
✕. Has an active infection requiring intravenous systemic therapy or hospital admission.
