Brief summary: This early phase 1 trial studies the use of everolimus in restoring salivary gland function in participants with locally advanced head and neck cancer after concurrent chemoradiation or radiation therapy alone.

Detailed description: PRIMARY OBJECTIVES:

I. To describe the recovery of salivary gland function after administration of a 5-day course of everolimus, administered two weeks after completion of radiation or chemoradiation therapy.

SECONDARY OBJECTIVES:

I. To describe the decrease of saliva flow rates during radiation or chemoradiation therapy.

II. To describe the changes in saliva protein composition during radiation or chemoradiation therapy and following administration of a 5-day course of everolimus.

OUTLINE: This is an early phase 1 proof of principal study.

Participants receive everolimus orally (PO) once daily (QD) for 5 days beginning 2 weeks after completion of radiation or chemoradiation treatment. Participants also undergo saliva output testing at baseline prior to radiation or chemoradiation treatment, after 3 weeks of RT/chemoRT, after 6 weeks of RT/chemoRT, prior to everolimus administration, at completion of the 5 day everolimus course, and at 1, 3, and 6 months after the completion of radiation or chemoradiation therapy.

Eligibility criteria: Inclusion Criteria:

* Performance status Eastern Cooperative Oncology Group (ECOG) ≤ 2
* Absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/L
* Platelets ≥ 100 x 10\^9/L
* Hemoglobin (Hgb) \> 9 g/dL
* Total serum bilirubin ≤ 2.0 mg/dL
* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x upper limits of normal (ULN) (≤ 5 x ULN in patients with liver metastases)
* International normalized ratio (INR) ≤ 2
* Serum creatinine ≤ 1.5 x ULN
* Fasting serum cholesterol ≤ 300 mg/dL or ≤ 7.75 mmol/L and fasting triglycerides ≤ 2.5 x ULN

  * NOTE: in case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication
* Signed informed consent obtained prior to any screening procedures
* Patients with locally advanced squamous cell carcinoma of the head and neck, treated with curative intent either in the post-operative or definitive setting with high dose radiotherapy (≥ 50 Gy) with or without chemotherapy

Exclusion Criteria:

* Patients currently receiving anticancer therapies or who have received anticancer therapies within 2 weeks of the start of everolimus (including chemotherapy, radiation therapy, antibody based therapy, etc.)
* Known intolerance or hypersensitivity to everolimus or other rapamycin analogs (e.g. sirolimus, temsirolimus)
* Known impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral everolimus
* Uncontrolled diabetes mellitus as defined by glycated hemoglobin (HbA1c) \> 8% despite adequate therapy; patients with a known history of impaired fasting glucose or diabetes mellitus (DM) may be included, however blood glucose and antidiabetic treatment must be monitored closely throughout the trial and adjusted as necessary
* Patients who have any severe and/or uncontrolled medical conditions such as:

  * Unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction ≤ 6 months prior to start of everolimus, serious uncontrolled cardiac arrhythmia, or any other clinically significant cardiac disease
  * Symptomatic congestive heart failure of New York heart Association class III or IV
  * Active (acute or chronic) or uncontrolled severe infection, liver disease such as cirrhosis, decompensated liver disease, and active and chronic hepatitis (i.e. quantifiable hepatitis B virus \[HBV\]-deoxyribonucleic acid \[DNA\] and/or positive hepatitis B virus surface antigen \[HbsAg\], quantifiable hepatitis C virus \[HCV\]-ribonucleic acid \[RNA\])
  * Known severely impaired lung function (spirometry and carbon monoxide diffusing capacity \[DLCO\] 50% or less of normal and oxygen \[O2\] saturation 88% or less at rest on room air)
  * Active, bleeding diathesis
* Chronic treatment with corticosteroids or other immunosuppressive agents; topical or inhaled corticosteroids are allowed
* Known history of human immunodeficiency virus (HIV) seropositivity
* Patients who have received live attenuated vaccines within 1 week of start of everolimus and during the study; patient should also avoid close contact with others who have received live attenuated vaccines; examples of live attenuated vaccines include intranasal influenza, measles, mumps, rubella, oral polio, Bacillus Calmette-Guerin (BCG), yellow fever, varicella and TY21a typhoid vaccines
* Patients who have a history of another primary malignancy, with the exceptions of: nonmelanoma skin cancer, and carcinoma in situ of the cervix, uteri, or breast from which the patient has been disease free for ≥ 3 years
* Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable or will not be able to complete the entire study
* Patients who are currently part of or have participated in any clinical investigation with an investigational drug within 1 month prior to dosing
* Pregnant or nursing (lactating) women
* Women of child-bearing potential (WOCBP) (including female pediatric patients who are menarcheal or who become menarcheal during the treatment), defined as all women physiologically capable of becoming pregnant, must use highly effective methods of contraception during the study and 8 weeks after; women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms); highly effective contraception methods include combination of any two of the following:

  * Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS) or other forms of hormonal contraception that have comparable efficacy (failure rate \< 1%), for example, hormone vaginal ring or transdermal hormone contraception; in case of use of oral contraception women should have been stable on the oral agent for a minimum of 3 months before taking everolimus
  * Total abstinence
  * Male partner sterilization; (the vasectomized male partner should be the sole partner for that subject)
  * Female sterilization have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks prior torandomization; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child-bearing potential
* Male patients whose sexual partner(s) are WOCBP who are not willing to use adequate contraception, during the study and for 8 weeks after the end of treatment
