Open-label Study to Evaluate the Safety, PK, and PD of MEK Inhibitor GSK1120212 in Subjects With Relapsed or Refractory Leukemias

6. března 2014 aktualizováno: GlaxoSmithKline

An Open-Label, Dose-Escalation, Phase I/II Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of the MEK Inhibitor GSK1120212 in Subjects With Relapsed or Refractory Leukemias

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.

An AE is any untoward medical occurrence in a participant (par.) or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury. Refer to the general Adverse AE/SAE module for a complete list of AEs and SAEs.

Časové okno: From the start of the study drug until the final study visit (up to approximately 407 days)
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.
