• Person who had plan of eradication Helicobacter pylori in 1 year 9 months
• Person who has history of previous Trametinib or other MEK inhibitor use.
• Person who has history of hypersensitivity to excipients.
• Person who entered clinical trial and took investigational new drug within 12 weeks.

Male or female patients of reproductive potential and, as judged by the investigator, are not employing an effective method of birth control and pregnant female.

Breast feeding female Have refractory nausea and vomiting , chronic gastrointestinal diseases (e.g . inflammatory bowel disease), or significant bowel resection that would adversely affect the absorption / bioavailability of the orally administered study medication.

Person who has history of hyperrefractory for Trametinib methyl sulfoxide Person who has pneumonia under chest X-ray. Have evidence of any other significant clinical disorder or laboratory finding that, as judgedby the investigator, makes it undesirable for the patient to participate in the study.
