Negative data from another trial led to termination of this trial by sponsor.

This phase I trial studies how well talactoferrin works in treating patients with relapsed or refractory non-small cell lung cancer (NSCLC) or squamous cell head and neck cancer. Biological therapies, such as talactoferrin, may stimulate the immune system in different ways and stop tumor cells from growing

PRIMARY OBJECTIVES:

I. Monitoring of immunologic response to therapy in tumor tissue and peripheral blood. Identification of potential candidate biomarkers indicating clinical benefit to talactoferrin.

SECONDARY OBJECTIVES:

I. Progression free survival (PFS), objective response rate (ORR), stable disease (SD), overall survival (OS), disease stability, and disease stability at 7 weeks.

OUTLINE:

Patients receive talactoferrin orally (PO) twice daily (BID) for 12 weeks. Courses repeat every 14 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up monthly for at least 12 months.

Inclusion Criteria:

Histologically or cytologically confirmed, incurable metastatic relapsed/refractory NSCLC or relapsed/refractory, incurable, locally advanced or metastatic squamous head and neck cancer Head and neck squamous cell cancer patients must be able to be biopsied safely in clinic or by Stanford Interventional Radiology as determined by a Stanford Head and Neck Oncologist or Stanford Head and Neck Surgeon Hemoglobin (Hgb) >= 9 gm/dl Platelets >= 80,000/uL International normalized ratio (INR) =< 1.5 Total bilirubin =< 1.5 Creatinine =< 1.5 Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2 times the upper limit of normal Failed therapy with at least one standard first line chemotherapy regimen, or intolerant of standard chemotherapy At least 4 weeks from the last chemotherapy, immunosuppressive/immunomodulatory therapy or investigational agent and 2 weeks from erlotinib or other non-immunogenic therapy Palliative radiotherapy to painful bony metastases must be completed at least 2 weeks prior to initiation of study treatment Brain metastases must be adequately treated (stable and asymptomatic) with surgery and/or radiation prior to enrollment and any steroids completed at least 3 weeks prior to study treatment initiation At least one un-irradiated target lesion measurable by Response Evaluation Criteria In Solid Tumors (RECIST) criteria At least one lesion amenable to repeat biopsy Life expectancy of at least 2 months Eastern Cooperative Oncology Group (ECOG) performance status 0-2 Absolute neutrophil count >= 1,000/µl Absolute lymphocyte count >= 800/µl Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

Concomitant chemotherapy, radiotherapy, immunosuppressive/immunomodulatory therapy or investigational agents Head and Neck Squamous Cell Carcinoma that can not be safely biopsied in Head and Neck Oncology Clinic or by Stanford Interventional Radiology as determined by a Stanford Head and Neck Oncologist or a Stanford Head and Neck Surgeon
