- How to Read a Study Record
- There are no established treatments for people with certain advanced kidney cancers. These tumors often don't respond well to currently available treatments. Researchers believe that two drugs that treat other diseases metformin and vandetanib could help people with advanced kidney cancer.
- To test the combination of metformin and vandetanib in people with advanced kidney cancer. Phase I of the study will determine a safe dose for the drugs. Phase II will test this dose in people with certain kidney cancers.
- For Phase I, people 18 and over with advanced kidney cancer
- For Phase II, people 18 and over with advanced hereditary leiomyomatosis and renal cell cancer (HLRCC), succinate dehydrogenase renal cell carcinoma (SDH-RCC), or advanced papillary renal cell carcinoma not related to a hereditary syndrome
- The study will last many months.
- Participants will be screened with medical history and physical exam.
- Participants will take the study drugs by mouth every day.
- Participants will measure and record their blood pressure every day.
- Participants will have many tests:
- Blood and urine tests
- Magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET) scan, and other imaging tests: they will lie in machines that take pictures of their body.
- Electrocardiogram (ECG): soft electrodes will be stuck to the skin. A machine will record the hearts signals.
- Bone scan
- Some participants may have a gynecology evaluation or photos of skin tumors taken.
- Participants will have an optional tumor biopsy.
- After they stop taking the drugs, participants may have medical history, physical exam, and blood tests. They will be contacted once a year by phone to find out how they are doing.

Experimental: Phase I Component - Vandetanib
Phase I Component
PHASE I: Vandetanib by mouth (PO) daily at 300mg in combination with escalating doses of metformin.
Other Name: Caprelsa
Phase I: Metformin starting dose 250mg by mouth (PO) daily in combination with Vandetanib
Other Name: Glucophage
Experimental: Phase II Component- Vandetanib/Metformin
Phase II Component
Phase II: Vandetanib and metformin by mouth (PO) daily at determined maximum tolerated dose (MTD).
- Phase 1 Component - Maximum Tolerated Dose (MTD) of Vandetanib and Metformin When Used in Combination in Patients With Metastatic Renal Cell Carcinoma (RCC) [ Time Frame: 42 days after the last patient starts therapy. ]MTD is the dose level at which no more than 1 of up to 6 patients experience dose limiting toxicity (DLT) during 1 cycle of treatment (42 days from the time the intended dose of metformin is reached for a given dose level), and the dose below that at which at least 2 (of ≤6) patients have DLT as a result of the experimental regimen. A DLT is defined as grade III or greater diarrhea leading to hospitalization or lasting > 48 hours despite optimal anti-diarrheal medication; grade IV diarrhea despite optimal anti-diarrheal prophylaxis; grade III or greater nausea or vomiting despite optimal antiemetics; grade III hypertension that is not controlled (to 140/90 mmHg or below) despite optimal antihypertensive therapy; grade III elevated serum creatinine that cannot be corrected to grade 1 or better with hydration within 48 hours; and electrolyte abnormalities that cannot be corrected with medical management within 72 hours.
- Phase 2 Component - Percentage of Participants With an Overall Response Rate Following Treatment With the Combination of Vandetanib and Metformin [ Time Frame: Approximately 8 weeks after initiation of therapy, every 8 weeks thereafter for the first 32 weeks, and then every 12 weeks while on treatment ]Percentage of participants with an overall response rate following treatment with the combination of vandetanib and metformin in patients with 1) advanced Renal Cell Carcinoma (RCC) associated with Hereditary leiomyomatosis and renal cell cancer (HLRCC) or Succinate Dehydrogenase (SDH), and 2) advanced sporadic/non-HLRCC Papillary Renal Cell Carcinoma assessed by the Response Evaluation Criteria in SOlid Tumors (RECIST) v1.1.
- Phase 2 Component - Progression Free Survival (PFS) [ Time Frame: Time from start of treatment to time of progression or death, whichever occurs first ]Progression-free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Progression was assessed by the and is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The appearance of one or more new lesions is also considered progressions.
- Phase 2 Component - Time to Progression (TTP) [ Time Frame: Approximately 8 weeks after initiation of therapy, every 8 weeks thereafter for the first 32 weeks, and then every 12 weeks while on treatment ]Time to progression is the time between the first day of treatment to the day of disease progression. Progression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) and is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The appearance of one or more new lesions is also considered progressions.
- Phase 1 Component - Number of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). [ Time Frame: Approximately 24 months ]Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
- Phase 1 Component - Number of Participants With a Dose Limiting Toxicity (DLT) [ Time Frame: Cycle 1 or 42 days from the time the intended dose of metformin is reached for a given dose level ]A DLT is defined as grade III or greater diarrhea leading to hospitalization or lasting > 48 hours despite optimal anti-diarrheal medication; grade IV diarrhea despite optimal anti-diarrheal prophylaxis; grade III or greater nausea or vomiting despite optimal antiemetics; grade III hypertension that is not controlled (to 140/90 mmHg or below) despite optimal antihypertensive therapy; grade III elevated serum creatinine that cannot be corrected to grade 1 or better with hydration within 48 hours; and electrolyte abnormalities that cannot be corrected with medical management within 72 hours.
