TAR-0520 Gel in EGFR Inhibitor-induced Folliculitis

Cetuximab and panitumumab hae become the standard treatment for patients with metastatic colorectal cancer without RAS gene mutation. Hoever, these EGFR inhbitors induce a broad spectrum of cutaneous toxicities (skin side effects) in 75-90% of patients, including the folliculitis involving the face,upper torso and scalp. The folliculitis appears within 1-2 weeks of anti-EGFR therapy and peaks around 3-5 weeks of treatment. There is no approved treatment to prevent or treat EGFR-induced folliculitis. Tarian Pharma has developed a new topical treatment of EGFRi-induced folliculitis.This study aims to confirm the good safety of TAR-0520 gel in colorectal cancer patients treated with cetuximab or panitmumab and eplore , in the same patients , the effect of TAR-0520 gel on the extent and severity of EGFRi-induced folliculitis.

Patients aged 18 years and over with metastatic colorectal carcinoma planned to be treated with cetuximab or panitumumab injections will be included in the study.

Participants will be randomly allocated to receive either the topical active TAR-0520 gel or its vehicle.The study will include a 7days treatment period with once daily applications of the test product followed by a treatment free period until the start of the next chemotherapy cycle usually 7 days later.The study will cover 4 complete chemotherapy cycles, thus lasting at least 56 days.
