Intermittent LGX818 and MEK162 in Treating Patients With Metastatic Melanoma Who Have BRAFV600 Mutations

Withdrawn before enrolling · Phase 2

Conditions studied: Recurrent Melanoma, Stage IV Melanoma

In brief

This phase II trial studies intermittent dosing of BRAF inhibitor LGX818 (encorafenib) and MEK inhibitor MEK 162 (binimetinib) in treating patients with melanoma that has spread to other parts of the body (metastatic) and have a BRAF V600 mutation. LGX818 and MEK162 may stop the growth of tumor cells by blocking different enzymes needed for cell growth. Giving LGX818 and MEK162 with breaks between each course (intermittently) may help delay the time when tumors become resistant to the drugs.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed written informed consent
• Histologically confirmed diagnosis of metastatic melanoma with the presence of the B-Raf proto-oncogene, serine/threonine kinase (BRAFV600) mutation
• Eastern Cooperative Oncology Group (ECOG) performance status < 3
• Absolute neutrophil count (ANC) >= 1.0 x 10\^9/L
• Hemoglobin (Hgb) >= 9 g/dL without transfusions
• Platelets (PLT) >= 90 x 10\^9/L without transfusions
• Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) =< 2.5 x upper limit of normal (ULN); patient with liver metastases =< 5 x ULN
• Total bilirubin =< 2 x ULN, or < 5 ULN if Gilbert’s disease
• Creatinine =< 1.5 mg/dL, or calculated creatinine clearance (determined as per Cockcroft-Gault) >= 50 mL/min
• Left ventricular ejection fraction (LVEF) >= 50% as determined by a multigated acquisition (MUGA) scan or echocardiogram (ECHO)
• Corrected QT (QTc) interval =< 480 ms
• Able to take oral medications
• Patient is deemed by the Investigator to have the initiative and means to be compliant with the protocol (treatment and follow-up)
• Negative serum beta (β) human chorionic gonadotropin (HCG) test (female patient of childbearing potential only) within 72 hours prior to first dose

You may not qualify if…

• Prior exposure to BRAF or MEK inhibitors
• Any active central nervous system (CNS) lesion (i.e., those with radiographically unstable, symptomatic lesions) and/or leptomeningeal metastases; however, patient treated with stereotactic radiotherapy, whole brain radiation or surgery are eligible if patient remained without evidence of CNS disease progression >= 4 weeks; patients must be off corticosteroid therapy for >= 2 weeks
• History or current evidence of retinal vein occlusion (RVO) or predisposing factors to RVO (e.g. uncontrolled glaucoma or ocular hypertension, history of hyperviscosity or hypercoagulability syndromes)
• History of retinal degenerative disease
• History of Gilbert’s syndrome
• Previous or concurrent malignancy is not an exclusion provided that the other malignancy is considered under control and target lesions from melanoma are clearly defined for response assessment
• 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, history or current evidence of clinically significant cardiac arrhythmia and/or conduction abnormality < 6 months prior to screening except atrial fibrillation and paroxysmal supraventricular tachycardia
• Uncontrolled arterial hypertension despite medical treatment
• Known positive serology for HIV (human immunodeficiency virus), active hepatitis B, and/or active hepatitis C infection
• Patients who have neuromuscular disorders that are associated with elevated creatine kinase (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, small bowel resection)
• Patients taking non-topical medication known to be a strong inhibitor of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4); however patients who either discontinue their treatment or switch to another medication at least three days prior to randomization are eligible
• 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, 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 8 weeks after study drug discontinuation; highly effective contraception methods include:
• Total abstinence when this is in line with the preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
• Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment; in case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
• Male sterilization (at least 6 months prior to screening); for female patients on the study, the vasectomized male partner should be the sole partner for that patient
• Combination of any of the two following (a+b or a+c or b+c)
• a. Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception
• b. Placement of an intrauterine device (IUD) or intrauterine system (IUS)
