The goal of this clinical research study is to find the highest tolerable dose of the combination of temsirolimus and metformin that can be given to patients with advanced cancer. The safety of the drug combination will also be studied.

Temsirolimus is designed to block a protein called mTOR (a protein that is thought to cause cancer cells to grow) inside the cancer cell. This may interfere with the growth or spread of cancer cells or possibly kill them.

Metformin was designed to treat patients with diabetes. It may be able to block the protein mTOR and slow the growth of tumors.

Primary Outcome Measures:
  • Maximum Tolerated Dose (MTD) of Temsirolimus and Metformin [ Time Frame: 10 weeks ]
    MTD defined as highest dose studied in which incidence of dose limiting toxicity (DLT) less than 33%. DLTs defined as adverse events (AEs) related to study agents which occur during first cycle of treatment. Toxicity must have possible, probable or definite attribution to study drugs.

Secondary Outcome Measures:
  • Clinical Tumor Response [ Time Frame: 10 weeks ]
    Clinical efficacy measured by objective tumor response per RECIST (Response Evaluation Criteria In Solid Tumors) criteria. Clinical response defined as Complete Response (CR) or Partial Response (PR) or at least 4 months Stable Disease (SD).

Estimated Enrollment: 104
Study Start Date: March 2012
Estimated Primary Completion Date: March 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Temsirolimus + Metformin
Starting dose of Temsirolimus 25 mg by vein weekly. Metformin titrated over 3 weeks at 500 mg by mouth daily. Four weeks of treatment constitute 1 cycle. Cycle one (1) however, will be 6 weeks long to allow for metformin titration.
Drug: Temsirolimus

Starting dose: 25 mg by vein weekly.

Expansion cohort: Once MTD is determined, or at maximum tolerated dose level explored (Level 5) if MTD is not reached, additional 14 patients enrolled.

Other Names:
  • CCI-779
  • Torisel
Drug: Metformin

Starting dose: 500 mg titrated over first 3 weeks.

Expansion cohort: Once MTD is determined, or at maximum tolerated dose level explored (Level 5) if MTD is not reached, additional 14 patients enrolled

Ages Eligible for Study:   14 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients with advanced or metastatic cancer that is refractory to standard therapies, who have relapsed after standard therapy, or whose cancers have no standard therapy that induces a complete response (CR) rate of at least 10% or improves survival by at least three months.
  2. Patients must have evaluable or measurable disease by RECIST criteria.
  3. Patients must be >/= 4 weeks beyond 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 wks, whichever is shorter, from the last day of treatment.
  4. Patients must be at least 5 half-lives beyond treatment with metformin and currently not taking metformin
  5. Patients may be on antidiabetic treatment other than Metformin
  6. ECOG performance status </= 1
  7. Abnormal organ function is permitted. However, patients must have absolute neutrophil count >/= 1000/mL; platelets >/= 75,000/mL; creatinine < 1.5 mg/dl in males and < 1.4 in females;T. Bilirubin </= 3 X upper limit of normal (ULN); AST(SGOT) and/or ALT(SGPT) </= 2 X ULN
  8. Women of child-bearing potential MUST have a negative serum or urine pregnancy test unless prior hysterectomy or menopause (defined as 12 consecutive months without menstrual activity). Patients should not become pregnant or breastfeed while on this study. Sexually active patients must agree to use contraception prior to study entry, for the duration of study participation, and for 30 days after the last dose
  9. Ability to understand and willingness to sign a written informed consent document.
  10. Patients must be >/= 14 years of age.
  11. Patients in the tumor-specific endometrial carcinoma expansion cohort that have known mutation must be willing to provide consent for biopsies.

Exclusion Criteria:

  1. Patients who are pregnant or breastfeeding.
  2. Uncontrolled intercurrent illness including, but not limited to, active infection requiring hospitalization.
  3. History of hypersensitivity to temsirolimus or metformin.
  4. History of CVA, myocardial infarction or unstable angina within the previous six months before starting therapy
  5. New York Heart Association Class III or greater congestive heart failure.
  6. Patients with major surgery within 30 days prior to entering the study.
  7. Patients unable to swallow oral medications or with pre-existing gastrointestinal disorders that might interfere with proper absorption of oral drugs.
  8. Patients on drugs that are strong P450 CYP3A4 modifiers. These drugs should be stopped 5 half-lives prior to starting investigational agents with temsirolimus. The strong inducing or inhibiting agents should not restart until 1 week after the end of the study treatment. NOTE: We will allow replacement of steroids (with either prednisone or hydrocortisone) in patients with adrenalectomy.
  9. Patients with a history of any grade of persistent or chronic nausea or vomiting within the last 4 weeks related to prior therapy or disease process.
