Trial overview

Official title: A Phase I, Single-Sequence, Placebo-Controlled, Single-Blind Study to Evaluate the Effect of Repeat Oral Dosing of GSK1120212 on Cardiac Repolarization in Subjects with Solid Tumors
Trial description: A multicenter, non-randomized, placebo-controlled, single dosing schedule, subject-blinded study to evaluate the effect of GSK1120212 on the electrical activity of the heart as compared to placebo in subjects with solid tumor cancers. All subjects will undergo Screening assessments within 21 days prior to the start of the study treatment to determine their eligibility for enrollment in the study. Eligible subjects will receive study treatment administered over a period of 15 days followed by a post-treatment follow-up visit. Study treatment (GSK1120212-matched placebo) will be blinded to subjects. Subjects will receive GSK1120212-matched placebo on one day during the first 14 days of dosing. On all other days the subject will receive a once-daily 2 mg dose of GSK1120212 except for Day 15 when the subject will receive 3mg dose of GSK1120212 12-lead ECG recordings will be obtained from continuous ECG recordings obtained via a 12-lead Holter monitor on Study Days 1 and 15 while subjects are in the clinical research unit. The effect of GSK1120212 on the electrical activity of the heart will be determined by time-matched ECGs obtained at the same time points relative to dosing on these days. Ambulatory blood pressure readings will be obtained from continuous 24-hour recordings via an ambulatory blood pressure monitor The effect of GSK1120212 on blood pressure parameters will be determined by blood pressure readings obtained at the same time points relative to dosing on Study Days 1 and 15. Serial blood samples to analyze the concentration of study drug in the subject’s blood will be obtained at the same time points relative to dosing on Study Days 1 and 15. Subjects who are eligible for continued treatment with GSK1120212 may continue treatment under the rollover study MEK114375 (drug study number). A post-treatment follow-up visit will be conducted within 28 days of the last dose of study treatment for all subjects who do not continue treatment in the rollover study MEK114375.

    Inclusion and exclusion criteria
    Inclusion criteria:
    • Inclusion Criteria
    • Has provided signed, written informed consent.
    • Male or female, age greater than and equal to 18 years of age at the time of signing the informed consent form.
    • Has histologically or cytologically confirmed diagnosis of a solid tumor malignancy that is not responsive to standard therapy(ies) or for which there is no approved therapy.
    • Has Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
    • Able to swallow and retain oral medication.
    • Has adequate baseline organ function as follows: System: Hematologic – absolute neutrophil count, Laboratory values: greater than and equal to 1.2 × 109/L;System: Hematologic
    • Hemoglobin, laboratory values: greater than and equal to 9 g/dL; System: Hematologic-platelets, laboratory values: greater than and equal to 75 × 109/L; System: Hematologic
    • Prothrombin time (PT), INR (international normalizing ratio
    • a blood clotting test))and Partial thromboplastin time (PTT), laboratory values: less than and equal to 1.5 times ULN(Upper limit of normal); System – Hepatic – Total bilirubin, laboratory values: less than and equal to 1.5 times ULN; System: Hepatic-ALT(Alanine aminotransferase), laboratory values: less than and equal to 2.5 times ULN; System: Renal-Creatine, laboratory values: less than anad equal to 1.5 times ULN; or System: Renal-Calculated creatinine clearance, laboratory values: greater than and equal to 50 mL/min; or System: Renal-24hour urine creatine clearance, laboratory values: greater than and equal to 50 mL/min; System: Cardiac-LVEF, laboratory values: greater than and equal to LLN (Lower limit of normal) by ECHO or MUGA(Multigated acquisition scan). Abbreviations: ALT, alanine aminotransferase; AST, aspartate aminotransferase; ECHO, echocardiogram; INR; LLN,lower limit of normal; LVEF, left ventricular ejection fraction; MUGA; PT, prothrombin time; PTT, partial thromboplastin time; ULN, upper limit of normal. INR greater than 1.5 times ULN will be acceptable in case of subjects receiving therapeutic anticoagulants such as warfarin as long as INR is monitored during the study according to clinical practice; Calculated by the Cockcroft-Gault formula; If LLN is not defined for a given institution, then ejection fraction must be greater than and equal to 50%. NOTE: Subjects with aspartate aminotransferase (AST), ALT or bilirubin values outside the range(s) in the table due to Gilbert’s syndrome or asymptomatic gallstones are not excluded. Laboratory results obtained during Screening should be used to determine eligibility criteria. In situations where laboratory results are outside the permitted range, the investigator may opt to retest the subject and the subsequent within-range screening result may be used to confirm eligibility.
    • Have serum potassium, serum magnesium, and total serum calcium levels within normal limits. NOTE: If total serum calcium is below the LLN, then it will be necessary to determine the albumin-corrected total serum calcium level. Use the following calculation: Calcium (mg/dL) = measured total Calcium (mg/dL) + 0.8 (4.0 – serum albumin [g/dL]) NOTE: If serum potassium or magnesium level is below the LLN, supplementation is permitted in order to meet the inclusion criterion. Subject should be retested following supplementation. In order to avoid a situation where the subject cannot be dosed during the study due to electrolyte levels falling below the LLN, it is strongly recommended to maintain serum potassium levels greater than 4 mEq(Milliequivalent )/L and serum magnesium levels greater than 2.2 mg/dL whenever possible. Slight elevations of potassium or magnesium above the upper limit of normal may be seen during supplementation and will not exclude subjects from study entry.
