Eligibility Criteria
-----------------
Inclusion Criteria: Diagnosed with mCRC; Currently being treated with an FDA approved EGFRI for the treatment of mCRC, including but not limited to Erbitux® (cetuximab) Injection and Vectibix® (panitumumab) Injection, as directed by the approved labeling; Treatment with the FDA approved EGFRI initiated within 12 weeks prior to the Screening Visit; Grade 1 or 2 acneiform lesions at the Screening and Baseline (Day 0) Visits; A minimum of 3 subjects per dose cohort must have Grade 2 non-infected acneiform lesions at the Screening and Baseline (Day 0) Visits; Age ≥18 years at the time of signing the informed consent form (ICF); Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2; Expected life expectancy greater than 3 months; Subject can understand and sign the ICF, can communicate with the Investigator, can understand and comply with the requirements of the protocol, and can apply the study drug by himself/herself or has a care giver that can apply the drug; Women of childbearing potential (WCBP) must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at baseline (Day 0); WCBP must agree to abstain from sex or use an adequate method of contraception from the time of informed consent through the Day 55 Visit and for 90 days after the last dose of study drug (LUT014); Males must abstain from sex with WCBP or use an adequate method of contraception from the time of informed consent through the Day 55 Visit and for 90 days after the last dose of study drug (LUT014). Exclusion Criteria: Active infection; Significant skin disease other than EGFRI induced acneiform lesions; Any cancer other than mCRC within 3 years of Screening; Any condition which, in the opinion of the Investigator, places the subject at unacceptable risk if he/she were to participate in the study; Clinically relevant serious co-morbid medical conditions including, but not limited to, unstable angina, symptomatic congestive heart failure, uncontrolled hypertension, uncontrolled cardiac arrhythmias, chronic obstructive or chronic restrictive pulmonary disease, active central nervous system (CNS) disease uncontrolled by standard of care, known positive status for human immunodeficiency virus (HIV) and/or active hepatitis B or C, cirrhosis, or psychiatric illness/social situations that would limit compliance with study requirements; Pregnant or lactating; Treatment with an EGFRI other than those specified in the inclusion criteria within 30 days or 5 half-lives of the drug prior to Screening, whichever is longer; Treatment with a serine/threonine-protein kinase B-Raf (B-Raf) inhibitor, including but not limited to Zelboraf® (vemurafenib), Tafinlar® (dabrafenib), BraftoviTM (encorafenib), and Nexavar® (sorafenib), within 30 days or 5 half-lives of the drug prior to Screening, whichever is longer; Treatment with a systemic antibiotic within 7 days prior to Screening; Treatment with a topical corticosteroid to the face, neck, or upper portion of the anterior or posterior chest within 14 days prior to Screening or treatment with a systemic corticosteroid within 14 days prior to Screening, except for low dose systemic corticosteroids (e.g., 8-20 mg dexamethasone or comparable) given for up to one or two days every two weeks as part of standard of care for the prevention or treatment of chemotherapy-induced nausea and vomiting (CINV) for subjects being treated with FDA-approved EGFRI and chemotherapy combinations for mCRC; Treatment with an oral retinoid within 7 days prior to Screening; Treatment with another investigational drug within 30 days or 5 half-lives of drug prior to Screening, whichever is longer; Known hypersensitivity to the inactive ingredients of the study drug (LUT014).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
