Brief Summary

Immunotherapy targeting the PD-1/PD-L1 pathway had previously been shown to be efficacious in the treatment of patients with metastatic head and neck squamous cell carcinomas. Stereotactic Body Radiotherapy (SBRT) to metastatic lesions causes localized cancer cell killing and the release of cancer cell debris, which could stimulate the immune system in the presence of immunotherapy. The purpose of this study is to assess the tolerability and efficacy of combining Durvalumab (MEDI4736), Tremelimumab and SBRT in controlling cancer progression. SBRT will be administered to patients while they are receiving Durvalumab and Tremelimumab.

Conditions

13. Eastern Cooperative Oncology Group/World Health Organisation (ECOG/WHO) performance status score of ≤ 1

14. Patients with locoregional recurrence(s) can be included only if they have evidence of distant metastasis; patients with locoregional recurrences which are symptomatic and/or potentially affect quality of life may undergo palliative radiation therapy to this region prior to enrollment on the protocol at the discretion of the treating physician. However, a minimum of 6 weeks must elapse before receiving protocol treatment.

• Haemoglobin ≥ 9.0 g/dL
• Absolute neutrophil count (ANC ≥ 1.5 (or 1.0) x (> 1500 per mm3)
• Platelet count ≥ 100 (or 75) x 109/L (>75,000 per mm3)
• Serum bilirubin ≤ 1.5 x institutional upper limit of normal (ULN). This will not apply to subjects with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only in consultation with their physician.
• AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be ≤ 5x ULN

16. Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:

• Women <50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
• Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).

17. Patient is willing and able to give written informed consent, prior to performing any protocol-related procedures, including screening evaluations.

18. Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

19. Patients who have received prior anti-PD-1, anti PD-L1 or anti CTLA-4, including durvalumab and tremelimumab if the following are fulfilled:
