Brief summary

MEK111759 is a dose-escalation, Phase I/II, open-label study to determine the recommended dose and regimen for the orally administered MEK inhibitor GSK1120212 in subjects with relapsed or refractory leukemias. The recommended dose and regimen will be selected based on the safety, pharmacokinetic, and pharmacodynamic profiles. This study will identify the maximum tolerated and recommended Phase II doses using a dose-escalation procedure. Dose escalations will continue based on predefined parameters until a maximum tolerated dose is established. In Phase II, the clinical efficacy of GSK1120212 in subjects with relapsed or refractory leukaemias (AML, MDS or CMML) will be determined.

Number of Participants With a Change From Baseline Grade to Grade 3 and 4 for the Indicated Clinical Chemistry Parameters by Dose

Hematology and clinical chemistry data were summarized according to NCI-CTCAE grade, version 3.0. Grade 1, Mild; Grade 2, Moderate; Grade 3, Severe; Grade 4, Life-threatening or disabling; Grade 5, Death. Data are presented for only those parameters for which an increase to Grade 3 or Grade 4 occurred. Clinical chemistry tests where the toxicity grade is defined by NCI-CTCAE includes albumin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase (AST), total bilirubin, calcium, creatinine, glucose, bicarbonate, potassium, magnesium, sodium, and phosphorus. Participants with missing Baseline grades were assumed to have a Baseline grade of 0. Only those participants (par.) with laboratory values for worst-case on-therapy are presented.

Time frame: From the start of the study drug until the final study visit (up to approximately 407 days)

Population: All Treated Population (ATP). Only those par. available at the specified time points were analyzed. Different par. may have been analyzed for different parameters; the overall number analyzed reflects everyone in the ATP. One Phase 2 par. was incorrectly dosed (received \<2 mg \[0.5 mg\]); thus, 6 par. receiving GSK1120212 \<2 mg OD were analyzed.

Number of Participants With a Change From Baseline Grade to Grade 3 and 4 for the Indicated Hematology Parameters by Dose

Hematology and clinical chemistry data were summarized according to National Cancer Institutes (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade, version 3.0. Grade 1, Mild; Grade 2, Moderate; Grade 3, Severe; Grade 4, Life-threatening or disabling; Grade 5, Death. Data are presented for only those parameters for which an increase to Grade 3 or Grade 4 occurred. Hematology tests where the toxicity grade is defined by NCI-CTCAE includes hemoglobin, international normalized ratio (INR), lymphocytes, total neutrophils, platelet count, and partial thromboplastin time (PTT). Participants with missing baseline grades were assumed to have a baseline grade of 0. Only those participants (par.) with laboratory values for worst-case on-therapy (defined as the worst shift that occurred at any time during the treatment period) are presented.

Time frame: From the start of the study drug until the final study visit (up to approximately 407 days)

Population: All Treated Population (ATP). Only those par. available at the specified time points were analyzed. Different par. may have been analyzed for different parameters; the overall number analyzed reflects everyone in the ATP. One Phase 2 par. was incorrectly dosed (received \<2 mg \[0.5 mg\]); thus, 6 par. receiving GSK1120212 \<2 mg OD were analyzed.

Number of Participants With an Investigator-assessed Best Response (Achieving Complete Response [CR], Marrow CR, Partial Response [PR], Complete Response Without Platelet Recovery [CRp] or Morphologic Leukaemia-free State[MLFS]) by Cohort

Overall response rate (ORR=CR+CRp+Marrow CR+MLFS+PR) was calculated from the investigator's assessment of response recorded within the first eight weeks of treatment. CR includes complete remission. Complete remission is a state in which the participant must be free of all symptoms related to leukemia and have an absolute neutrophil count \>=1 x 10\^9/L, platelet count \>=100 x 10\^9/L, and normal marrow differential (\<=5% blasts). PR includes partial remission. Partial remission is a state in which the participant has a CR with 6 to 25% abnormal cells in the marrow or 50% decrease in bone marrow blasts. CRp is as per CR but platelet count \<100 x 10\^9/L. MLFS is a state in which the participant has a normal marrow differential (\<5% blasts), neutrophil, and platelet counts are not considered.

Time frame: From the start of the study drug until the final study visit (up to approximately 407 days)

Population: Efficacy Population: all participants included in the All Treated Population who had received at least one dose of 2 mg of study drug in Phase 2.
