A Study of the Effect of Sorafenib or Regorafenib on p63 Expression and Keratinocyte Differentiation in Human Skin
Principal Investigator (?)
Study Number
D11004
Summary
Skin toxicity is a frequently observed side effect in the era of "molecularly targeted therapies". Skin toxicity following administration of protein kinase inhibitors such as sorafenib, regorafenib, lapatinib, sunitinib, and others can be debilitating to the patient, resulting in dose reduction and discontinuation of treatment. The mechanisms of skin toxicity induced by targeted chemotherapy, such as sorafenib or regorafenib, are poorly understood. Further research is warranted to better understand the pathophysiology of drug-related skin toxicity in this setting and develop correction strategies. This study tests the hypothesis that sorafenib and regorafenib interfere with p63 expression and keratinocyte differentiation and skin remodeling. Eligible study participants will be evaluated clinically for evidence of skin toxicity during their visits to the outpatient Oncology clinics. Study participants will undergo skin biopsies before sorafenib or regorafenib treatment is initiated and once rash develops or 12 weeks into treatment with sorafenib or regorafenib. Skin biopsies will be performed in Oncology clinics by the study investigators and clinic support staff. Study participants will undergo both skin biopsies regardless of whether they develop a rash. In patients who develop a rash the most representative lesion will be biopsied. A normal appearing area of skin will be biopsied in participants who do not develop a rash.
