Exclusion criteria

Subjects who meet any of the following criteria are not eligible for enrollment.

• A skin examination reveals the presence of any active disease (e.g., eczema), tattoos or other problems, such as open lesions, that could make the application site unacceptable for study drug lotion application, located on the face/neck and/or upper chest that, in the Investigator's opinion, could confound the evaluation of the rash;
• Any clinically significant safety laboratory or diagnostic results that, in the opinion of the Investigator, would place the subject at undue risk if the subject were to participate in the study;
• Any clinically significant finding or concurrent clinical illness in the physical examination or medical history that, in the opinion of the Investigator, would place the subject at undue risk if the subject were to participate in the study;
• Undergoing any current treatment for cancer other than the prescribed EGFRI that in the opinion of the Investigator, would place the subject at undue risk if the subject were to participate in the study;
• Prior treatment with any other marketed or investigational EGFRI therapy within the 3 months prior to screening (Visit 1);
• Treatment with topical antibiotics, topical steroids, and other topical treatments on the face/neck and upper chest within 14 days of first study lotion application;

• Any subjects with prior history of bleeding and hematologic disorders;
• Clinically significant abnormal laboratory values at screening, to include but not limited to the following hematologic, renal and liver function laboratory values:

• Hematologic function:

• Hemoglobin < 9.0 gL/dL or < 10.0 g/dL for subjects receiving hematopoietic growth factors, such as darbopoeitin alfa or epoetin alfa
• ANC < 1,500/mm3 (or < 1.5 ×109/L)
• Platelet count < 100,000/mm3 (or < 100 ×109/L)
• Renal function:

• Serum creatinine > 1.5 mg/dL or < 133 umol/L (SI units) or calculated estimated creatinine clearance < 60 ml/min/1.73 m2 based on Cockcroft and Gault formula
• Hepatic function:

• Aspartate transaminase (AST) or alanine transaminase (ALT) > 3 × institutional upper limit of normal (ULN) or > 5 × institutional ULN if documented liver metastasis
• Total bilirubin > 2 × institutional ULN or > 5 × institutional ULN if documented liver metastasis
• Treatment with any cosmetic cream, make-up or products such as sun screen, oils, powders, perfumes, lotions, ointments, etc. to the anticipated study lotion application area within 3 days before treatment or during the treatment period;
