简要总结
The purpose of this study is to determine the efficacy and safety of pembrolizumab given concomitantly with chemoradiation (CRT) and as maintenance therapy versus placebo plus CRT in participants with locally advanced head and neck squamous cell carcinoma (LA HNSCC). The primary hypothesis is that pembrolizumab in combination with CRT is superior to placebo in combination with CRT with respect to event-free survival (EFS).
研究者
入排标准
入选标准
- •Has a pathologically proven new diagnosis of oropharyngeal p16 positive, oropharyngeal p16 negative, or larynx/hypopharynx/oral cavity (independent of p16) squamous cell carcinoma. Participants with oral cavity tumors need to have unresectable disease. Participants with multiple synchronous tumors are not eligible for the study.
- •Has provided tissue for Programmed Cell Death Receptor Ligand 1 (PD-L1) biomarker analysis from a core or excisional biopsy. If an excisional or incisional biopsy has been performed, participants remain eligible for the study provided the residual disease meets the staging criteria required for the trial (e.g., excisional biopsy of a lymph node with residual T4 primary). Prior surgical debulking, including tonsillectomy, for the head and neck cancer under study is not allowed.
- •Has evaluable tumor burden (measurable and/or non-measurable tumor lesions) assessed by computed tomography scan or magnetic resonance imaging, based on RECIST version 1.1
- •Is eligible for definitive CRT and not considered for primary surgery based on investigator decision
- •Has Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 performed within 10 days prior to receiving the first dose of study therapy
- •Female participants of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of study therapy
- •Female and male participants of reproductive potential must agree to use adequate contraception throughout the study period and for up to 180 days after the last dose of study therapy
排除标准
- •Is currently participating or has participated in a study with an investigational agent or using an investigational device within 4 weeks of the first dose of study therapy
- •Has received prior therapy with an anti-Programmed Cell Death Receptor 1 (PD-1), anti-PD-L1, anti-Programmed Cell Death Receptor Ligand 2 (PD-L2) agent or with an agent directed to another co-inhibitory T-cell receptor or has previously participated in clinical studies with pembrolizumab
- •Has received a live vaccine within 30 days prior to the first dose of study therapy
- •Has cancer outside of the oropharynx, larynx, and hypopharynx or oral cavity, such as nasopharyngeal, sinus, other para-nasal, or other unknown primary head and neck cancer
- •Has had prior systemic therapy, targeted therapy, radiotherapy treatment or radical surgery for head and neck cancer under study
- •Has not recovered from major surgery prior to starting study therapy
- •Has known active Hepatitis B or C
- •Has known history of Human Immunodeficiency Virus (HIV)
- •Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study therapy
- •Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
研究组 & 干预措施
Pembrolizumab + Cisplatin + CRT
Participants receive a priming dose of pembrolizumab before initiation of CRT (either accelerated or standard fractionation radiotherapy regimen). During CRT, participants receive 2 doses of pembrolizumab and up to 3 cycles of Cisplatin (2 cycles during accelerated and 3 cycles during standard fractionation radiotherapy). Participants also receive up to an additional 14 cycles of pembrolizumab alone as maintenance therapy for a total of 17 cycles of pembrolizumab. If cisplatin and/or radiation therapy is discontinued, the participant may continue on treatment with pembrolizumab.

结局指标
主要结局
Event-free Survival (EFS)
时间窗: Up to approximately 62 months
EFS was defined as the time from date of randomization to the date of first record of any of the following events: death due to any cause; progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR) or biopsy as indicated for locoregional progression or recurrence or distant metastasis. As well as the first record of the following types of surgery: salvage surgery for persistent or residual disease at the primary tumor site requiring surgical removal when invasive cancer is present on final pathology; neck dissection or surgery (performed for clinical or radiological disease progression per RECIST 1.1) ≤ 20 weeks from end of CRT when invasive cancer is present; or neck dissection or surgery \>20 weeks from end of CRT when invasive cancer is present. The non-parametric Kaplan-Meier method was used to estimate the EFS curve in each treatment group.
