Brief summary: This phase I trial studies the side effects and best dose of sapanisertib and metformin in treating patients with cancers that have spread to other parts of the body (advanced/metastatic), have come back (recurrent), or do not respond to treatment (refractory). Sapanisertib and metformin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description: PRIMARY OBJECTIVES:

I. To evaluate the safety and tolerability and to determine maximum tolerated dose (MTD) of the combination of sapanisertib (TAK-228) with metformin in patients with advanced cancers refractory to standard therapy.

SECONDARY OBJECTIVES:

I. To assess the clinical tumor response of this combination. II. To characterize the pharmacokinetic (PK) profile of metformin and TAK-228.

OUTLINE: This is a dose escalation study.

Patients receive metformin orally (PO) 1-3 times daily on days 1-42 and sapanisertib PO daily on days 15-42 of cycle 1. Patients then receive metformin PO daily and sapanisertib PO daily on days 1-28 of cycle 2 and beyond. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up within 30 days.

Eligibility criteria: Inclusion:

1. Male or female patients 18 years or older.
2. Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
3. Female patients who: Are postmenopausal for at least 1 year before the screening visit, OR Are surgically sterile, OR If they are of childbearing potential, agree to practice 1 highly effective method of contraception and one additional effective (barrier) method at the same time, from the time of signing the informed consent through 90 days (or longer as mandated by local labeling \[eg USPI, SmPC, etc\] 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 (Periodic abstinence \[e.g, calendar, ovulation, symptothermal, postovulation methods\], withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.) MUST have a negative serum or urine pregnancy test within 7 days of initiating protocol treatment unless prior hysterectomy or menopause (defined as 12 consecutive months without menstrual activity).
4. CONTINUED FROM #3: Patients should not become pregnant or breastfeed while on this study. The effects of TAK-228 and metformin on the developing human fetus are unknown. Should a woman become pregnant or suspect she is pregnant, she should inform her 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.
6. Eastern Cooperative Oncology Group (ECOG) performance status and/or other performance status \</= 1.
7. Adequate organ function, as specified below, within 7 days before the first dose of study drug: a) Bone marrow reserve consistent with: absolute neutrophil count (ANC) \>/= 1.5 x 10\^9/L; platelet count \>/= 100 x 10\^9/L; hemoglobin \>/= 9 g/dL without 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.
8. Ability to swallow oral medications.
9. Patients with diabetes are allowed and may be on antidiabetic treatment other than Metformin. The diabetes must be under control within normal range (HbA1C \</=7%).
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.
