14. 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:

1) 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 folliclestimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).

2) 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).

15. Written informed consent obtained prior to performing any protocol-related procedures, including screening evaluations

Exclusion Criteria:

1. Nasopharyngeal, paranasal sinuses, nasal cavity tumors or thyroid cancers

2. Metastatic disease

3. Active CNS disease

4. Any prior or current treatment for invasive head and neck cancer

5. Any unresolved toxicity NCI CTCAE v5.0 Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria.

   1. Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis
   2. Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the investigator

6. Major surgical procedure (as defined by the investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable

7. History of leptomeningeal carcinomatosis

8. Body weight ≤ 30 kg and/or weight loss of ≥ 15% during the last 4 weeks (except if renutrition with a feeding tube is planned before the onset of treatment or is ongoing)

9. Concurrent treatment with any other systemic anti-cancer therapy that is not specified in the protocol

10. Concomitant treatment with any drug on the prohibited medication list such as live vaccines within 30 days prior to the first dose of IP

15. Uncontrolled intercurrent illness, including but not limited to, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent
