Summary

The goal of the Phase I portion of this study is to find the highest tolerable dose of the combination of dasatinib and erlotinib hydrochloride that can be given to patients with advanced solid tumors.

Asymptomatic brain metastasis without prior treatment are acceptable if the largest lesion is less than 7 mm in diameter, there is no bleeding, midline shift, nor need for steroids or anti-convulsants.

13. Patient agrees to discontinue St. Johns Wort at least 5 days before starting dasatinib or erlotinib.

14. Patient agrees that IV bisphosphonates will be withheld for the first 8 weeks of dasatinib therapy due to risk of hypocalcemia.

17. (Phase I only) - Histological or unequivocal cytological proof of solid tumor malignancy.

18. (Phase I only) - At least one prior systemic chemotherapy or biological therapy for recurrent or metastatic solid tumor (i.e., this protocol therapy must be administered as second line or greater), ), except if there is no standard or experimental systemic therapy available. If no effective systemic agent is available for first line therapy, then patients may be enrolled on the phase I as first line therapy.

19. (Phase I only) - Prior radiotherapy is permitted (see exclusion criterion 4 for details on unallowable radiotherapy).

20. (Phase II only) - Histological or unequivocal cytological proof of NSCLC.

21. (Phase II only) - NSCLC that is appropriate for systemic therapy without curative intent: Stage IV, Stage IIIB with pleural effusion, or incurable recurrent disease after surgery or radiotherapy.

22. (Phase II only) - Zero to one line of prior systemic therapy for recurrent or metastatic NSCLC. Prior adjuvant chemotherapy or adjuvant biologic therapy for NSCLC is not included as a line of prior therapy if it was completed greater than 3 months prior to recurrence, provided that the patient has never received any EGFR or SFK inhibitors.

23. (Phase II only) - Measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

24. (Phase II only) - Availability of tumor tissue that is at least adequate for EGFR mutational analysis. This can come from pre-existing paraffin blocks (from diagnostic biopsy or surgical resection) or patient may undergo a biopsy for research purposes.

25. (Phase II only) - Prior radiotherapy is permitted as long as there is measurable disease outside of the radiotherapy port OR clearly recurrent and growing within the radiotherapy port (see exclusion criterion 2 for details on unallowable radiotherapy).

Exclusion Criteria:

1. Women who are pregnant, breastfeeding, or have child-bearing potential and are unwilling/unable to use an acceptable method of contraception for the entire study period and for at least 4 weeks after cessation of the study drugs. All women of child-bearing potential must have a negative pregnancy test prior to first receiving protocol therapy. If the pregnancy test is positive, the patient must not receive dasatinib or erlotinib, and must not be enrolled on the study

2. Radiotherapy to ribs, sternum, pelvis, vertebrae or skull within 4 weeks prior to entering the study. (If none of these axial skeletal areas are included in the radiotherapy field, patients may have received palliative radiotherapy to long bones provided that it has ended at least 2 weeks prior to initiation of dasatinib-erlotinib therapy.)

3.
