Vandetanib in Combination With Metformin in People With HLRCC or SDH-Associated Kidney Cancer or Sporadic Papillary Renal Cell Carcinoma

• Status: Terminated
• Trial end date: 2020-02-06
• Target enrollment: 0
• Participant gender: All

Summary

Background:

• 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.

Objective:

• 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.

Eligibility:

• 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

Design:

• 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.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Metformin

Criteria

• INCLUSION CRITERIA:

1. Diagnosis/Histology

1. Phase I Component - Histologically confirmed advanced Renal Cell Carcinoma (RCC) of any subtype.

2. Phase II Component - Advanced RCC associated with 1) Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) or Succinate dehydrogenase (SDH) (Cohort 1); OR 2) advanced non HLRCC-related papillary RCC (Cohort 2).

2. Phase 1: Patients must have evaluable disease

Phase 2: Patients must have measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST 1.1) criteria, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >20 mm with conventional techniques or as >10 mm with spiral computed tomography (CT) scan or magnetic resonance imaging (MRI) (except for lymph nodes, which must be >15 mm).

3. Prior Therapy

1. Phase 1- Patients with clear cell RCC must have either declined, be ineligible to receive, have progressed on, or be intolerant to high dose Interleukin 2 (IL-2), or standard first and second line Vascular endothelial growth factor (VEGF), or mammalian target of rapamycin (mTOR) targeted agents. As there is no standard therapy for metastatic non-clear cell RCC, no prior therapy is required.

2. Phase 2- No more than two prior VEGF-pathway targeted agents

3. No previous treatment with vandetanib. Previous or ongoing treatment with metformin is allowed.

4. Age greater than or equal to18 years.

5. Eastern Cooperative Oncology Group (ECOG) performance status <2 (Karnofsky >60%).

6. Negative pregnancy test (urine or serum) for female patients of childbearing potential.

7. Patients must have normal organ and marrow function as defined below:

absolute neutrophil count greater than or equal to 1,500/mcL

platelets greater than or equal to 100,000/mcL

total bilirubin less than or equal to 1.5x upper limit of reference range ( < 3x upper limit of reference range in patients with Gilbert's disease)

aspartate aminotransferase (AST)(serum glutamic-oxaloacetic transaminase (SGOT)/alanine aminotransferase (ALT)(Serum glutamic pyruvic transaminase (SGPT) less than or equal to 2.5 X institutional upper limit of normal

Estimated glomerular filtration rate (eGFR) (Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) greater than or equal to 50 mL/min/1.73 m^2

8. Men and women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) for the duration of study participation and for at least 6 months after vandetanib/metformin therapy. Should a woman become pregnant (either a participant or the partner of a male participant) or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately.

9. Ability of subject to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

1. Known serious allergic reaction to vandetanib or metformin.

2. Brain metastases or spinal cord compression that requires treatment, unless the treatment ended at least 4 weeks before starting protocol therapy and the condition has been stable without steroid treatment for at least 10 days.

3. Major surgery (includes any surgery that carries significant risk of blood loss, extended periods of general anesthesia, or requires at least an overnight hospital admission) within 28 days before starting treatment or inadequately healed incision/scar from prior surgery.

4. Any unresolved chronic toxicity greater than Common Terminology Criteria for Adverse Event (CTCAE) Grade 2 or greater from previous anti-cancer therapy (this criterion does not apply to alopecia).

5. Unacceptable electrolyte values, including:

• Potassium <4.0 mmol/L despite supplementation, or elevated potassium above the CTCAE Grade 1 upper limit.

• Magnesium below the lower limit of normal range despite supplementation, or elevated magnesium above the CTCAE Grade 1 upper limit.

9. Past medical history of interstitial lung disease, drug-induced interstitial disease, radiation pneumonitis which required steroid treatment or any evidence of clinically active interstitial lung disease.

10. Proteinuria > 1gram/24 hrs

11. Evidence of severe or uncontrolled systemic disease or any concurrent condition which in the Investigators opinion makes it undesirable for the patient to participate in the trial or which would jeopardize compliance with the protocol.
