A Study of Vismodegib in Patients With Relapsed/Refractory Acute Myelogenous Leukemia and Relapsed Refractory High-Risk Myelodysplastic Syndrome
A PHASE IB/II STUDY TO EVALUATE THE SAFETY AND EFFICACY OF VISMODEGIB IN RELAPSED/REFRACTORY ACUTE MYELOGENOUS LEUKEMIA (AML) AND RELAPSED/REFRACTORY HIGH-RISK MYELODYSPLASTIC SYNDROME (MDS)
This study will assess the safety and efficacy of vismodegib in patients with relapsed/refractory acute myelogenous leukemia (AML) and relapsed/refractory high-risk myelodysplastic syndrome (MDS). Patients in Cohort 1 will receive single-agent vismodegib 150 mg orally daily. In Cohort 2, patients will receive vismodegib 150 mg orally daily in combination with cytarabine 20 mg subcutaneously for 10 days.
Anticipated time on study treatment is until disease progression, intolerable toxicity, or patient withdrawal of consent.

Percentage of Participants With a Complete Response (CR) or CR With Incomplete Blood Count Recovery (CRi) or Morphologic Leukemia Free State (MLFS) or Partial Response (PR) at Week 8
Časové okno: Week 8

CR was defined as achieved if the neutrophils count was greater than (>) 1000 cells per microliter (µL), platelets count >100000/µL, bone marrow blasts percentage (%) less than (<) 5, no Auer rods (clumps of azurophilic granular material that form elongated needles seen in the cytoplasm of leukemic blasts), no transfusion requirements and no signs of extra medullary disease (EMD).
CRi was defined if either of the cell (neutrophil or platelet) lineage was not recovered (neutrophils >1000 cells/µL or Not applicable [NA] or platelets count >100000/µL or NA), bone marrow blasts <5% with no Auer rods and confirmed by flow cytometry with no signs of EMD.
MLFS (neutrophil and platelet criteria were NA) was defined as bone marrow blasts <5% with no Auer rods and confirmed by flow cytometry with no signs of EMD.
PR was defined as neutrophils count >1000 cells/µL, platelets count >100000/µL, and >50% decrease from baseline to a range of 5-25% of bone marrow blasts or blasts <5% with Auer rods.

|
Median Overall Survival (OS) Time

OS was defined as the time from start of study drug to death from any cause.
OS was estimated using Kaplan-Meier analysis.
Participants alive at the last date known to be alive were censored for the analysis.
