Trial of RAD001 and Erlotinib With Recurrent Head and Neck Squamous Cell Carcinoma

The goal of this clinical research study is to learn if RAD001 in combination with Tarceva (erlotinib hydrochloride) can help to control head and neck squamous cell cancer (HNSCC). The safety of this drug combination will also be studied.

The Study Drugs:

RAD001 is designed to stop cancer cells from multiplying. It may also stop the growth of new blood vessels that help tumor growth, and this may cause the tumor cells to die.

Erlotinib hydrochloride is designed to block the activity of a protein found on the surface of many tumor cells that may control tumor growth and survival. This may stop tumors from growing.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will take 1 RAD001 tablet and 1 erlotinib hydrochloride tablet every day of each 28 day study "cycle".

Both drugs should be taken at the same time, by mouth, with a cup (8 ounces) of water. You should take the drugs at least 1 hour before or 2 hours after eating. You should take the study drugs at around the same time each day. Your eating habits around the time you take the drugs should stay the same while you are on study. lf you vomit, you should not take another tablet until your next scheduled dose.

Tell your doctor if you have any side effects, as your dose(s) of study drug(s) may be lowered or stopped for a few days. You may be given drugs to help reduce the risk of side effects.

Study Visits:

On Day 1 (+/- 3 days) of each cycle, the following tests and procedures will be performed:

* You will have a complete physical exam, including measurement of your weight and vital signs.
* You will be asked about any drugs you may be taking and any side effects you may be having.
* Your performance status will be recorded.
* Blood (about 3 teaspoons) will be drawn for routine tests. If your doctor thinks it is needed, you may have to have these blood tests more often.

On Day 1 (+/- 3 days) of every evenly numbered cycle (Cycles 2, 4, 6, and so on), you will have a CT scan or MRI scan to check the status of the disease.

Length of Study:

You may continue to take the study drugs for as long as you are benefitting. You will be taken off study if the disease gets worse or if you have intolerable side effects.

End-of-Study Visit:

When you go off study for any reason, you will have an end-of-study visit. The following tests and procedures will be performed:

* Your medical history will be recorded.
* You will have a complete physical exam, including measurement of your weight and vital signs.
* You will be asked about any drugs you may be taking and any side effects you may be having.
* Your performance status will be recorded.
* Blood (about 3 teaspoons) will be drawn for routine tests.
* You will have a CT scan or MRI scan to check the status of the disease.

Follow-Up:

You will be called within 30 days after the end-of-study visit and asked how you are doing and about any possible side effects that you may have had. The call should take about 5 minutes.

This is an investigational study. RAD001 is FDA approved and commercially available for the treatment of certain types of breast cancer. Erlotinib hydrochloride is FDA approved and commercially available for the treatment of advanced non-small cell lung carcinoma (NSCLC) and advanced pancreatic cancer. The use of this drug combination for the treatment of HNSCC is investigational.

Up to 35 patients will take part in this study. All will be enrolled at MD Anderson.

Eligibility Criteria:
Inclusion Criteria:

1. Histologically or cytologically confirmed squamous cell carcinoma of the head and neck
2. Patients that have failed one platinum-containing chemotherapy regimen with or without EGFR inhibitor and/or epidermal growth factor receptor (EGFR) inhibitor as systemic therapy for recurrent/metastatic disease. Prior investigational therapy (with the exclusion of mammilian target of rapamycin (mTOR) inhibitor) allowed but at least 4 weeks must have elapsed with recovery from all toxicities
3. Patients who had prior induction or concurrent chemotherapy delivered as part of their primary treatment are eligible as long as they have completed primary therapy at least 6 months prior to study entry.
4. Patients must have at least one measurable site of disease according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria that has not been previously irradiated. If the patient has had previous radiation to the marker lesion(s), there must be evidence of progression since the radiation
5. Age \>/= 18 years
6. Minimum of two weeks since any major surgery or completion of radiation. Note: Patients may have received prior radiation therapy to tumor sites that will not be assessed for response, unless there is evidence of progression.
7. Completion of all prior systemic anticancer therapy for the treatment of recurrent/metastatic disease (adequately recovered from the acute toxicities of any prior therapy) at least 4 weeks prior to study entry
8. Eastern Cooperative Oncology Group (ECOG) performance status \</= 2
9. Laboratory Values (within 14 days prior to administration of study drugs): Adequate bone marrow function as shown by: absolute neutrophil count (ANC) \>/= 1.5 \* 10\^9/L, Platelets \>/= 100 \* 10\^9/L, Hgb \> 10 g/dL; Adequate liver function as shown by: serum bilirubin \</=1.5 \* upper limit of normal (ULN), and serum transaminases activity \</= 3 \* ULN.

Exclusion Criteria:

1. Prior treatment with any investigational drug within the preceding 4 weeks, concomitant chemotherapy, hormonal therapy, radiotherapy or immunotherapy, or therapy with agents otherwise used in treatment of cancer (for example, methotrexate for rheumatoid arthritis)
