treatment physician immediately. Male patients, even if surgically sterilized (ie,
status post-vasectomy), who: Agree to practice highly effective barrier contraception
during the entire study treatment period and through 120 days after the last dose of
study drug, or Agree to practice true abstinence, when this is in line with the
preferred and usual lifestyle of the patient, as described in #3 above. Agree not to
donate sperm during the course of this study or within 120 days after receiving their
last dose of study drug.
5. Patients must have a diagnosis of advanced or metastatic malignancy that is refractory
to standard therapies, who have relapsed after standard therapy, or whose cancers have
no standard therapy that induces a CR rate of at least 10% or improves survival by at
least three months.

transfusion within 1 week preceding study drug administration; b) Hepatic: total
bilirubin </= 1.5 x upper limit of normal (ULN), transaminases (aspartate
aminotransferase/serum glutamic oxaloacetic transaminase-AST/SGOT and alanine
aminotransferase/serum glutamic pyruvic transaminase-ALT/SGPT) </= 2.5 x ULN (</= 5 x
ULN if liver metastases are present); c) Renal: creatinine clearance >/=50 mL/min
based either on Cockroft-Gault estimate or based on urine collection (12 or 24 hour);
d) Metabolic: fasting serum glucose (</= 130 mg/dL) and fasting triglycerides </= 300
mg/dL.

10. Patients must be at least 5 half-lives beyond previous treatment with metformin and
currently not taking metformin.
11. Patients must be >/= 4 weeks beyond previous treatment of any chemotherapy, other
investigational therapy, hormonal, biological, targeted agents or radiotherapy, and
must have recovered to </= grade 1 or previous baseline for each toxicity. Exception:
Patients may have received palliative low dose radiotherapy to the limbs 1-4 weeks
before this therapy provided pelvis, sternum, scapulae, vertebrae, or skull were not
included in the radiotherapy field. Patients who have received non-chemotherapeutic
biological agents will need to wait at least 5 half-lives or 4 weeks, whichever is
shorter, from the last day of treatment of non-chemotherapeutic biological agents.
12. Patients must have evaluable or measurable disease by RECIST 1.1 criteria. These
measurements will be done by the Quantitative Imaging Analysis Core (QIAC) group.
Exclusion:

pregnancy test during the screening period or a positive urine pregnancy test on Day 1
before first dose of study drug.
2. Any serious medical or psychiatric illness that could, in the investigator's opinion,
potentially interfere with the completion of treatment according to this protocol.
3. Participation in other clinical trials, including those with other investigational
agents not included in this trial, within 5 half lives of those investigational agents
before the start of this trial and throughout the duration of this trial.
4. Manifestations of malabsorption due to prior gastrointestinal (GI) surgery, GI
disease, or for an unknown reason that may alter the absorption of TAK-228. In
addition, patients with enteric stomata are also excluded.
5. Poorly controlled diabetes mellitus defined as glycosylated hemoglobin (HbA1c) > 7%;
patients with a history of transient glucose intolerance due to corticosteroid

independent of symptom control with medical intervention, or history of valve
