carcinoma of the head and neck at the following sites: oral cavity, oropharynx,
hypopharynx and larynx with either:

- Stage IV p16 positive tumors and >10 pack-years smoking history.

- Stage III/IV p16 negative tumors, regardless of smoking history.

- At least evaluable disease; one measurable site of disease according to RECIST
(Version 1.1) criteria (at least 10 mm for conventional CT/MRI or spiral CT scan) is
desirable.

- Subjects enrolled in the MTD expansion cohort must have at least 1 tumor lesion that
is suitable for repeat biopsy (pre- and post-CUDC-101 infusion).

- If female, neither pregnant nor lactating

- If of child bearing potential, must use adequate birth control throughout the
participation in the treatment phase and for 60 days following the last study
treatment.

- Absolute neutrophil count ≥ 1,800/µL; platelets ≥ 100,000/µL; hemoglobin ≥ 8.0 g/dL,
creatinine ≤ 1.5x upper limit of normal (ULN); total bilirubin ≤ 1.5x ULN; AST/ALT ≤ 2
x ULN.

- Serum magnesium and potassium within normal limits (may be supplemented to achieve
normal values)

- Able to render informed consent and to follow protocol requirements.

Exclusion Criteria:

- Prior radiotherapy to the region of the study cancer or adjacent anatomical sites, or
> 25% of marrow-bearing area.

in the past 6 months prior to Day 1 of treatment, serious arrhythmias requiring
medication for treatment.

treatment.

- Symptomatic cardiac conduction abnormality within 12 months prior to study treatment.

- Prior history of hearing impairment.

- Known history of renal disease or ongoing renal impairment.

- Any uncontrolled condition (such as active systemic infection, diabetes,

participation in the study.
