5. Fasting glucose =/< 120 mg/dL (6.7 mmol/L).

6. Total calcium (corrected for serum albumin) within normal limits (8.8 - 10.5 MG/DL). This is MD Anderson Cancer Center (MDACC) lab standard. Supplements for calcium allowed to meet eligibility criteria.

7. Magnesium >/= the lower limit of normal (1.8 MG/DL). Supplements for magnesium allowed to meet eligibility criteria

8. Potassium within normal limits (3.5 - 5.0 milliequivalent (MEq)/L). Supplements for potassium allowed to meet eligibility criteria

9. international normalized ratio (INR) =/< 2

10. Women of childbearing potential, defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months), must have a negative serum or urine pregnancy test within 48 hours prior to the start of study drug

11. Patients should be able to take oral medications.

Exclusion Criteria:

1. Patients who have received myelosuppressive chemotherapystarting study drug (with the exception of Hydroxyurea which will be allowed during Course 1 of treatment).

2. Patients who have received targeted anticancer therapy ≤ 2 week (for non myelosuppressive therapy) prior to starting study drug.

3. central nervous system (CNS) disease

4. Patient has active cardiac disease including any of the following: Left ventricular ejection fraction (LVEF) < 50% as determined by Multiple Grated acquisition (MUGA) scan or echocardiogram (ECHO), corrected QT interval (QTc) > 480 msec on screening ECG (using the QTcF formula), Angina pectoris that requires the use of anti-anginal medication, Ventricular arrhythmias except for benign premature ventricular contractions, Supraventricular and nodal arrythmias requiring a pacemaker or not controlled with medication, Conduction abnormality requiring a pacemaker, Valvular disease with document compromise in cardiac function, Symptomatic pericarditis

5. Patient has a history of cardiac dysfunction including any of the following:

Myocardial infraction within the last 6 months, documented by persistent elevated cardiac enzymes or persistent regional wall abnormalities on assessment of LVEF function Documented congestive heart failure (New York Heart Association functional classification III-IV) Documented cardiomyopathy

6. Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g., e.g., uncontrolled infection, such as persistent fever despite antibacterial therapy) that could cause unacceptable safety risks or compromise compliance with the protocol. Significant symptomatic deterioration of lung function. If clinically indicated, pulmonary function tests including measures of predicted lung volumes, diffusion capacity of lung for carbon monoxide (DLco), O2 saturation at rest on room air should be considered to exclude pneumonitis or pulmonary infiltrates.

7. Patient has poorly controlled diabetes mellitus or steroid-induced diabetes mellitus

8. Patients with acute or chronic liver, renal disease or pancreatitis

9. Patients with diarrhea >/= CTCAE grade 2

10. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of BKM120 (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection). Patients with unresolved diarrhea will be excluded as previously indicated

11. Patients who have been treated with any hematopoietic colony-stimulating growth factors (e.g., G-CSF, GM-CSF)or darbepoetin therapy, if initiated at least 2 weeks prior to enrollment, may be continued

12. Patients with the following mood disorders as judged by the Investigator or a psychiatrist, or as a result of patient's mood assessment questionnaire: a. Medically documented history of or active major depressive episode, bipolar disorder (I or II), obsessive-compulsive disorder, schizophrenia, a history of suicidal attempt or ideation, or homicidal ideation (immediate risk of doing harm to others) b. >/= CTCAE grade 3 anxiety c. Meets the cut-off score of >/= 10 in the Patient Health Questionnaire PHQ-9 or a cut-off of >/= 15 in the General Anxiety Disorder GAD-7 mood scale, respectively, or selects a positive response of "1, 2, or 3" to question number 9 regarding potential for suicidal thoughts in the PHQ-9 (independent of the total score of the PHQ-9) will be excluded from the study unless overruled by the psychiatric assessment

13. Patients who have received prior treatment with a PI3K inhibitor

14. Patients with a known hypersensitivity to BKM120 or to its excipients

15. Patients who are currently receiving treatment with medication with a known risk to prolong the QT interval or inducing Torsades de Pointes and the treatment cannot either be discontinued or switched to a different medication prior to starting study drug. Please refer to table 4-7 or a list of prohibited QT prolonging drugs with risk of Torsades de Pointes

16. Patients who are currently treated with drugs known to be moderate and strong inhibitors or inducers of isoenzyme CYP3A, and the treatment cannot be discontinued or switched to a different medication prior to starting study drug. If treatment with such an inhibitor is in the best interest of the patient, extreme caution should be taken with its concomitant use. Please refer to Table 4-6 for a list of prohibited inhibitors and inducers of CYP3A (Please note that co-treatment with weak inhibitors of CYP3A is allowed)

17. Patients receiving chronic treatment with steroids or another immunosuppressive agent

18. Patients who have taken herbal medications and certain fruits within 7 days prior to starting study drug. Herbal medications include, but are not limited to St. John's wort, Kava, ephedra (ma huang), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto, and ginseng.

Double barrier contraceptives must be used through the trial by both sexes. Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are therefore not considered effective for this study. Women of child-bearing potential must have a negative serum or urine pregnancy test ≤ 48 hours prior to initiating treatment.

22. Known diagnosis of human immunodeficiency virus (HIV) infection

23. History of another malignancy within 3 years, except cured basal cell carcinoma of the skin or excised carcinoma in situ of the cervix and squamous cell carcinoma in situ of the skin.
