The purpose of this study is to determine whether the combination of palbociclib with cetuximab is superior to cetuximab in prolonging overall survival in HPV-negative, cetuximab-naive patients with recurrent/metastatic squamous cell carcinoma of the head and neck.

Official Title

A Randomized, Multicenter, Double-blind Phase 2 Study Of Palbociclib Plus Cetuximab Versus Cetuximab For The Treatment Of Human Papillomavirus-negative, Cetuximab-naïve Patients With Recurrent/Metastatic Squamous Cell Carcinoma Of The Head And Neck After Failure Of One Prior Platinum-containing Chemotherapy Regimen


Squamous Cell Carcinoma of the Head and Neck (SCCHN) palbociclib, cetuximab, human papillomavirus, squamous cell carcinoma, head and neck cancer Carcinoma Carcinoma, Squamous Cell Head and Neck Neoplasms Palbociclib Cetuximab Palbociclib plus Cetuximab


For people ages 18 years and up

Key Inclusion Criteria:

  • Histologically or cytologically confirmed squamous cell carcinoma of the oral cavity,oropharynx, hypopharynx or larynx, not amenable for salvage surgery or radiotherapy.
  • Measurable disease as defined per RECIST v. 1.1. Tumor lesions previously irradiated or subjected to other locoregional therapy will only be deemed measureable if disease progression at the treated site after completion of therapy is clearly documented.
  • HPV- negative SCCHN tumor as determined per institutional standard (eg, p16 IHC;multiplex nucleic acid sequence based amplification [NASBA] or other polymerase chain reaction [PCR]-based assays).
  • Documented progressive disease according to RECIST v1.1 (Appendix 2) following receipt of at least 2 cycles of one platinum-containing chemotherapy regimen administered for R/M disease (min. 50 mg/m2 for cisplatin, minimum area under the curve [AUC] > 4 for carboplatin).
  • Availability of a tumor tissue specimen (ie, archived formalin fixed paraffin embedded tissue [block preferred, or 15 unstained slides]), which will be used for centralized,retrospective biomarker analysis. If archived tumor tissue is not available, then a de novo biopsy will be required for patient participation.

Key Exclusion Criteria:

  • Prior nasopharyngeal cancer, salivary gland or sinus tumors.
  • More than one chemotherapeutic regimen given for R/M disease. Prior treatment with immunotherapy is allowed.
  • Known active uncontrolled or symptomatic central nervous system (CNS) metastases,carcinomatous meningitis, or leptomeningeal disease as indicated by clinical symptoms,cerebral edema, and/or progressive growth. Patients with a history of CNS metastases or cord compression are eligible if they have been definitively treated with local therapy (eg, radiotherapy, stereotactic surgery) and are clinically stable off anticonvulsants and steroids for at least 4 weeks before randomization.
  • Progressive disease within 3 months after completion of curatively intended treatment for locoregionally advanced SCCHN.
  • Difficulty swallowing capsules.
  • Prior use of cetuximab in the R/M disease treatment setting (except cetuximab during curative radiotherapy)
