This is a Phase 1b, open label, dose-finding study to determine the Maximum Tolerated Dose (MTD) of MEK162 in combination with mFOLFIRI, and to evaluate the response rate, clinical benefit rate and additional safety parameters of the treatment combination


Inclusion Criteria: - Age > 18 years old - Patients with histologically confirmed KRAS positive metastatic colorectal cancer. - Patients must have progressed during or after first-line treatment for metastatic disease with oxaliplatin and fluoropyrimidines based chemotherapy (with failure within six months) or not be a candidate for oxaliplatin (i.e. neuropathy). - ECOG Performance Status 0-1 - Able to provide informed consent and willing to sign an approved consent form that conforms to federal and institutional guidelines. - Women of childbearing potential must have a negative blood pregnancy test at the screening visit - Adequate bone marrow, organ function and laboratory parameters as defined by the protocol - Adequate cardiac function as defined by the protocol - Must have recovered from adverse effects of any prior surgery, radiotherapy or other antineoplastic therapy. Alopecia and CTCAE grade 1 peripheral neuropathy is acceptable - Willingness and ability to comply with all study procedures and able to take oral medications Dose Expansion Phase Additional Inclusion Criteria - Patients must be willing and able to undergo biopsy according to the institute's own guidelines and requirements for such procedures - Patients must have measurable disease as defined by RECIST v1.1 (at least one lesion ≥ 10mm in at least one dimension when assessed by CT or MRI, or a cutaneous lesion with clearly defined margins that measures ≥ 10 mm in at least one dimension) - Patients must be irinotecan refractory. Patients must have progressed on prior irinotecan therapy but must be able to tolerate standard irinotecan doses. Exclusion Criteria: - UGT1A1 *28 homozygous patients - Previous treatment with any MEK inhibitor - Treatment with systemic antineoplastic therapy (including unconjugated therapeutic antibodies and toxin immunoconjugates) or any investigational therapy within 4 weeks (<6 weeks for nitrosurea or mitomycin-C, antibodies except for trastuzumab) or within 5-half lives of the investigational therapy prior to starting study treatment, whichever is longer - Patient received radiotherapy within 2 weeks prior to the first dose of study treatment except localized radiation therapy for symptomatic bone metastasis. - Have had a diagnosis of another malignancy, unless the patient has been disease-free for at least 3 years following the completion of curative intent therapy, with the following exceptions: - Patients with treated non-melanoma skin cancer, in situ carcinoma, or cervical intraepithelial neoplasia, regardless of the disease-free duration, are eligible for this study if definitive treatment for the condition has been completed. - Patients with organ-confined prostate cancer with no evidence of recurrent or progressive disease based on prostate-specific antigen (PSA) values are also eligible for this study if hormonal therapy has been initiated or a radical prostatectomy has been performed. - History or current evidence of retinal vein occlusion (RVO) or current risk factors for RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyperviscosity or hypercoagulability syndromes. - Personal history of Gilbert's syndrome. - Uncontrolled arterial hypertension defined by blood pressure >150 mmHg systolic and/or 100 mmHg diastolic at rest (average 3 consecutive readings at least 5 minutes apart) despite appropriate medical therapy. - Impaired cardiovascular function or clinically significant cardiovascular diseases, including any of the following: - History of acute coronary syndromes (including myocardial infarction, unstable angina, coronary artery bypass grafting, coronary angioplasty, or stenting) <6 months prior to screening, - Symptomatic chronic heart failure; evidence of clinically significant cardiac arrhythmias and/or conduction abnormalities < 6 months prior to screening except atrial fibrillation and paroxysmal supraventricular tachycardia. - Known positive serology for HIV, active Hepatitis B, and/or active Hepatitis C infection (Note: if not suspected, testing is not required at baseline). - Patients who have neuromuscular disorders that are associated with elevated CK (e.g., inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy). - Patients who are planning on embarking on a new strenuous exercise regimen after first dose of study treatment. Muscular activities, such as strenuous exercise, that can result in significant increases in plasma CK levels should be avoided while on MEK162 treatment. - Impairment of gastrointestinal function or gastrointestinal disease (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection that under the judgment of the PI may impair absorption of study drugs). - Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g., infection/inflammation, intestinal obstruction, unable to swallow medication.(patients may not receive drug through a feeding tube), social/ psychological issues, etc. - Patients who have undergone major surgery ≤ 3 weeks prior to starting study drug or who have not recovered from side effects of such procedure. - Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test. - Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception throughout the study and for 15 days after study drug discontinuation. - Sexually active males unless they use a condom during intercourse while taking the drug and for 15 days after stopping treatment and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid. - Medical, psychiatric, cognitive or other conditions that may compromise the patient's ability to understand the patient information, give informed consent, comply with the study protocol or complete the study.
