Descriptive Information
Brief Title  ICMJE Study of Pembrolizumab (MK-3475) or Placebo With Chemoradiation in Participants With Locally Advanced Head and Neck Squamous Cell Carcinoma (MK-3475-412/KEYNOTE-412)
Official Title  ICMJE A Randomized Phase III Study of Pembrolizumab Given Concomitantly With Chemoradiation and as Maintenance Therapy Versus Chemoradiation Alone in Subjects With Locally Advanced Head and Neck Squamous Cell Carcinoma (KEYNOTE-412)
Brief Summary 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).

    Other Name: KEYTRUDA®
  • Drug: Placebo
    Normal saline or dextrose solution administered as an IV infusion Q3W
  • Drug: Cisplatin
    100 mg/m^2 administered as an IV infusion Q3W
    Other Names:
    • Platinol®
    • Platinol®-AQ
  • Radiation: Accelerated Fractionation (AFX) Radiotherapy
    70 Gray (Gy) given in 35 fractions over 6 weeks
  • Radiation: Standard Fractionation (SFX) Radiotherapy
    70 Gy given in 35 fractions over 7 weeks
Study Arms  ICMJE
  • Experimental: 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.
    Interventions:
    • Biological: Pembrolizumab
    • Drug: Cisplatin
    • Radiation: Accelerated Fractionation (AFX) Radiotherapy
    • Radiation: Standard Fractionation (SFX) Radiotherapy
  • Placebo Comparator: Placebo + Cisplatin + CRT
    Participants receive placebo before initiation of CRT (either accelerated or standard fractionation radiotherapy regimen). During CRT, participants receive 2 doses of placebo 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 placebo alone for a total of 17 cycles of placebo. If cisplatin and/or radiation therapy is discontinued, the participant may continue on treatment with placebo.
    Interventions:
    • Drug: Placebo
    • Drug: Cisplatin
    • Radiation: Accelerated Fractionation (AFX) Radiotherapy
    • Radiation: Standard Fractionation (SFX) Radiotherapy

Eligibility Criteria  ICMJE

  • 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

  • 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
  • Has an active autoimmune disease that has required systemic treatment in the past 2 years. Replacement therapy is not considered a form of systemic treatment.
  • Has history of a diagnosed and/or treated hematologic or primary solid tumor malignancy, unless in remission for at least 5 years prior to randomization
  • Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis
  • Has had previous allogeneic tissue/solid organ transplant
  • Has active infection requiring systemic therapy
  • Has a history of severe hypersensitivity reaction to pembrolizumab, Cisplatin or radiotherapy or their analogs
