Skin Toxicity in Patients With Metastatic Colorectal Cancer Treated With Anti-EGFR and Chemotherapy (DERMIA)

Clinical evidence has suggested that sub-antimicrobial doses of doxycycline may have the potential to treat inflammatory lesions of acne. The efficacy of doses below 100 mg/day of doxycycline in the prevention of skin toxicity in patients with treated with Epidermal Growth Factor Receptor (EGFR)-targeted therapies has never been studied. Therefore, the aim of the present study is to describe the efficacy of doxycycline 50 or 100 mg per day in the prevention of skin toxicity in patients with metastatic Colorectal cancer (mCRC) treated with anti-EGFR in combination with chemotherapy.
