Pharmacokinetic Study of BKM120 in Subjects With Hepatic Impairment

To assess pharamcokinetics, safety and tolerability of a single oral dose of BKM120 in subjects with mild, moderate and severe hepatic impairment


Eligibility Criteria:
Inclusion Criteria:

* Subjects should be in good health (except for additional/ specific inclusion criteria related to hepatic impaired subjects) as determined by past medical history, physical examination, vital signs, electrocardiogram, and laboratory tests of no significance at screening

  ---Additional inclusion criteria Group 1 - control healthy subjects
* Subjects should be matched to the hepatic impaired subjects of group 2 in gender, age (± 10 years), weight (± 20%), and BMI (±5%)

  ---Additional inclusion criteria Group 2 - hepatic impaired subjects
* Subjects with physical signs consistent with stable hepatic impairment
* Child-Pugh Clinical Assessment Score consistent with degree of hepatic impairment (mild , moderate or severe)

  * Additional exclusion criteria Group 2- hepatic impaired subjects
* Subjects with clinically significant abnormal findings, not consistent with clinical disease, upon physical examination, ECG or laboratory evaluation
