Eligibility

Inclusion Criteria:

Patients who meet each of the following criteria will be considered "eligible":

• Histologically or cytologically confirmed diagnosis of squamous cell carcinoma of the head and neck.
• Disease must be considered incurable. Incurable is defined as metastatic disease or a local or regional recurrence in a previously irradiated site that is unresectable (or patient declines resection).
• Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as >10 mm with CT scan, as >20 mm by chest x-ray, or >10 mm with calipers by clinical exam.
• Patients may have received pembrolizumab, platins, cetuximab or other chemotherapies in the metastatic setting, but do not need to have received cetuximab.
• Measurable disease per RECIST v1.1 as determined by the investigator;
• The subject has had an assessment of all known disease sites e.g., by computerized tomography (CT) scan, magnetic resonance imaging (MRI), bone scan as appropriate, within 28 days before the first dose of cabozantinib.
• A CT of the neck and a CT of the chest will be required at baseline for all patients.
• The subject is = 18 years old on the day of consent.
• The subject has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Recovery to baseline or = Grade 1 CTCAE v.5.0 from toxicities related to any prior treatments, unless AE(s) are clinically nonsignificant and/or stable on supportive therapy.
• The subject has organ and marrow function and laboratory values as follows within 14 days before the first dose of cabozantinib.

1. The ANC = 1500/mm3 without colony stimulating factor support.

2. White blood cell count = 2500/mm3 (= 2.5 GI/L).

3. Platelets = 100,000/mm3;

4. Hemoglobin = 9 g/dL;

5. Bilirubin = 1.5 x the ULN. For subjects with known Gilbert's disease, bilirubin = 3.0 mg/dL;

6. Albumin = 2.8 g/dl;

7. Creatinine = 2.0 x ULN or creatinine clearance (CrCl) = 40 mL/min. For creatinine clearance estimation, the Cockcroft and Gault equation should be used: i. Male: CrCl (mL/min) = (140 - age) × wt (kg) / (creatinine × 72); h. Female: Multiply above result by 0.85; Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) = 3 x upper limit of normal (ULN). ALP = 5 x ULN with documented bone metastases. i. Lipase < 2.0 x the upper limit of normal and no radiologic or clinical evidence of pancreatitis. j. UPCR = 1. k. Phosphorus, calcium, magnesium and potassium = LLN.

• The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document;
• Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (e.g., male or female condom) during the course of the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used. All subjects of reproductive potential must agree to use both a barrier method and a second method of birth control during the course of the study and for 4 months after the last dose of study drug(s).
• Female subjects of childbearing potential must not be pregnant at screening. Females of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e., females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low body weight, ovarian suppression or other reasons.
• No Grade 3-4 hypersensitivity reaction to cetuximab. Exclusion Criteria:

Patients who meet any of the following criteria will be considered "ineligible":

• Any patient who has received >70 Gy of XRT to the neck in the same radiation field. No head and neck radiation within 2 months prior to initiation. Treatment areas should be healed with no sequelae from RT that would predispose to fistula formation.
• A history of other malignancy = 5 years previous with the exception of basal cell or squamous cell carcinoma of the skin which were treated with local resection only, carcinoma in situ of the cervix, synchronous H&N primaries or low grade tumors deemed cured and not treated with systemic therapy.

Intervention

Drug:
• Cabozantinib
Cabozantinib will be initiated at 40 mg PO daily, with subsequent 20 mg or 40 mg doses as tolerated per the study design.
• Cetuximab
Cetuximab will be administered at 500 mg/m^2 intravenously every other week on Days 1 and 15 of each cycle, with a window of up to 3 days before the scheduled date. In an effort to prevent a hypersensitivity reaction, it is recommended that all patients pre-medications, hydration, and anti-emetics will be given according to institutional guidelines and/or per treating physician discretion.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	maximum tolerated dose (MTD)	from 3 testing dose levels: 20, 40, and 60. Three patients will be enrolled at the dose level 0 of 40 mg. The dose escalation scheme is as follows: If none of the initial three patients at a given dose level experience DLT within 4 weeks, the next dose level will be studied.; If one of the initial three patients at a given dose level experiences DLT, three additional patients will be treated at the same dose level. Escalation will continue only if there is no additional DLT observed.If two or more patients experience DLT at a given dose, the previous dose level will be studied. Should two or more patients experience the DLT at the lowest dose level (20 mg), the study will be halted, and alternative dosing will be considered.; 4. The highest dose level with no more than one DLT among six patients will be declared as the MTD. If only three patients were treated at a dose under consideration as the MTD, an additional three patients will be treated at that level.	2 years
