Brief 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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

  • Body Weight \>30kg
  • For women of childbearing potential, a negative serum or urine pregnancy test within 14 days prior to the start of treatment for their NPC. Women will be considered postmenopausal if they are amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: - Women 1 year ago, had chemotherapy-induced menopause with last menses \>1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).

  • 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.
