A Phase II, Randomized, Open-Label, Multi-Center, Global Study of MEDI4736 Monotherapy, Tremelimumab Monotherapy, and MEDI4736 in Combination With Tremelimumab in Patients With Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck (SCCHN)


Brief Summary
The purpose of this study is to determine the efficacy and safety of investigational medical products (MEDI4736 monotherapy, tremelimumab monotherapy, and MEDI4736 + tremelimumab combination therapy) in the treatment of patients with recurrent or metastatic carcinoma of the head and neck who have progressed during or after treatment with a platinum containing regimen for recurrent/metastatic disease.

Detailed Description
This is a randomized, open-label, multi-center, global, Phase II study to determine the efficacy and safety of MEDI4736 + tremelimumab combination therapy, MEDI4736 monotherapy and tremelimumab monotherapy in the treatment of patients with recurrent or metastatic PD-L1-negative squamous cell carcinoma of the head and neck (SCCHN) who have progressed during or after treatment with only 1 systemic palliative regimen for recurrent or metastatic disease, that must have contained a platinum agent. Patients will be randomized in a stratified manner according to prognostic factors, including human papillomavirus (HPV) status and smoking status to achieve a balance between treatments for each of the factors. Patients will be randomized in a 1:1:2 fashion to receive MEDI4736 monotherapy, tremelimumab monotherapy, or MEDI4736 + tremelimumab combination. All treatments will be administered beginning on Day 0 for 12 months or until confirmed progression of disease; unless, in the Investigator's opinion, the patient continues to receive benefit from the treatment), initiation of alternative cancer therapy, unacceptable toxicity, withdrawal of consent, or another discontinuation criterion is met. Patients with confirmed progression of disease who, in the Investigator's opinion, continue to receive benefit from their assigned investigational product and who meet the criteria for treatment in the setting of progression of disease may continue to receive their assigned investigational product treatment for a maximum of 12 months after consultation with the Sponsor and at the Investigator's discretion. The monotherapy arms (tremelimumab and MEDI4736) should be discontinued if there is confirmed progression of disease following a previous response in target lesions (complete response or partial response). Tumor assessments will be performed using computed tomography or magnetic resonance imaging. Efficacy for all patients will be assessed by objective tumor assessments every 8 weeks (q8w) for the first 48 weeks (relative to the date of the first infusion) then q12w in patients who have disease control after 12 months until confirmed objective disease progression. Following completion or discontinuation of treatment, patients will enter a follow-up period.


Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.

  • Histologically confirmed squamous cell carcinoma of any other primary anatomic location in the head and neck;
  • Received more than 1 regimen for recurrent or metastatic disease
  • Any concurrent chemotherapy, Investigational Product, biologic, or hormonal therapy for cancer treatment;
  • Receipt of any investigational anticancer therapy within 28 days or 5 half-lives;
  • Receipt of last dose of an approved (marketed) anticancer therapy (chemotherapy, targeted therapy, biologic therapy, mAbs, etc) within 21 days prior to the first dose of study treatment;
  • Major surgical procedure within 28 days prior to the first dose of Investigational Product;
  • Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criterion;
  • Current or prior use of immunosuppressive medication within 14 days before the first dose of their assigned Investigational Product;

  • Uncontrolled intercurrent illness;
  • another primary malignancy
  • Patients with history of brain metastases, spinal cord compression, or a history of leptomeningeal carcinomatosis;
  • History of active primary immunodeficiency;
  • Known history of previous tuberculosis;
  • Active infection including hepatitis B, hepatitis C or human immunodeficiency virus (HIV);
  • Receipt of live, attenuated vaccine within 30 days prior to the first dose of Investigational Product;
