Platelets >=100 x 109/L, Hgb >=10g/dL.

8. Subjects must have normal organ function as defined below:

- AST (SGOT) / ALT (SGPT) ≤ 2 x upper limit of normal (ULN),

- Serum creatinine ≤ 1.5 x ULN or creatinine clearance > 60 ml/min

- Coagulation markers - PT and PTT (or INR) within normal limits unless subjects
are already anti-coagulated for other reasons (i.e., atrial fibrillation, etc.).

9. Signed written informed consent to participate in the study.

10. Ability to comply with the requirements of the study.

Exclusion Criteria:

1. Participation in an investigational trial within 30 days of the screening visit.

2. History of allergic reactions attributed to compounds of similar chemical or biologic
composition to erlotinib or docetaxel.

3. Have a previous (unless disease free for more than five years) or concurrent

4. Subjects with known brain metastases or spinal cord compression that is newly

permitted..

5. Subjects with preexisting neuropathy ≥ grade 2.

6. Current serious infections.

7. Current known acute or chronic infection with HBV or HCV.

8. Known human immunodeficiency virus (HIV) infection.

9. Any significant ophthalmologic abnormality, especially severe dry eye syndrome,
keratoconjunctivitis sicca, Sjögren syndrome, severe exposure keratitis or any other
disorder likely to increase the risk of corneal epithelial lesions. The use of
contact lenses is not recommended during the study. The decision to continue to wear
contact lenses should be discussed with the patient's treating Oncologist and the
ophthalmologist.

10. Subjects with other concurrent severe and/or uncontrolled medical condition which
could compromise participation in the study (i.e. active infection, uncontrolled
diabetes, uncontrolled hypertension - grade 4, congestive cardiac failure, unstable
angina, ventricular arrhythmias, active ischemic heart disease, myocardial infarction
within six months, chronic liver or renal or metabolic disease, active upper GI tract
ulceration).

11. Any chronic or acute condition susceptible of interfering with the evaluation of drug
effect.

12. Any form of substance abuse (including drug or alcohol abuse), psychiatric disorder
or any chronic condition susceptible, in the opinion of the investigator, of
interfering with the conduct of the study.

13. Organ allograft or previous history of stem cell transplantation.

14. Subjects who received anti-neoplastic therapy, radiation therapy or had surgery
within 28 days prior to the start of study agent administration or who have not
recovered from the toxic effects of such therapy. Palliative localized radiation is
allowed.

15. Subjects who cannot take oral medication, who require intravenous alimentation, have
had prior surgical procedures affecting absorption, or have active peptic ulcer
disease.

16. Fertile subjects who are not willing to use an acceptable method of contraception
during the treatment period and for 28 days following completion of treatment.

17. For women of child-bearing potential: A positive pregnancy test at screening or
breast-feeding.

18. Subjects who are likely to be non-compliant or uncooperative during the study.
