Summary

The purpose of this study is to evaluate the effectiveness and safety of the combination of Pembrolizumab (KEYTRUDA) and the investigational drug, Metformin.

Description

Patients are being asked to take part in this clinical research study because they have advanced, un-resectable stage III or IV Melanoma. If they participate they will be randomized to receive Pembrolizumab (KEYTRUDA) or the combination of Pembrolizumab (KEYTRUDA) plus Metformin.

This research study will evaluate the effectiveness and safety of the combination of Pembrolizumab (KEYTRUDA) and the investigational drug, Metformin.

Patients will be randomized into one of two groups - either Arm A or Arm B. In Arm A, patients will receive pembrolizumab alone. In Arm B, patients will receive both pembrolizumab and metformin.

If patients are randomized to Arm A, they will be administered pembrolizumab (200 mg), by IV, every three weeks. After the first three doses, pembrolizumab dosing can be changed to 400mg IV every 6 weeks, at the treating physician's discretion. Pembrolizumab can be administered up to two years, if disease does not progress or have unacceptable toxicity. However, if the disease progresses the patient may continue on the study if they are clinically stable or clinically improved.

If patients are randomized to Arm B, they will be administered pembrolizumab (200 mg), by IV, every three weeks, plus metformin (500 mg), twice a day for nine weeks. Metformin will be taken in the morning and evening, 12hrs apart, with food. After the first three doses, pembrolizumab dosing can be changed to 400mg IV every 6 weeks, at the treating physician's discretion.

Discontinuation of treatment may be considered for patients who have attained a confirmed complete response that have been treated for at least 24 weeks with pembrolizumab and had at least two treatments with pembrolizumab beyond the date when the initial complete response was declared.

Patients will be followed for 5 years after removal from study or until death, whichever occurs first, through standard of care visits, phone call or by medical records review.

Be willing and able to provide written informed consent for the trial
Have un-resectable (stage III) or advanced (stage IV) melanoma
Be 18 years of age or older on day of signing informed consent
Have measurable disease based on RECIST 1.1. Patients without measurable disease may be included on study after discussion with the Sponsor, given that the primary endpoint of the study is Ki-67 of TIL (flow cytometry)
Have biopsiable disease. Be willing to provide tissue from a newly obtained biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 30 days prior to initiation of treatment on Day 1
Patients may have received prior adjuvant therapy with anti-PD-1, anti-CTLA-4, or BRAF/MEK inhibitors
Patients may be immunotherapy treatment nave in the advanced setting or may be on anti-PD-1 therapy with SD or PR for at least 12 weeks. Patients may have received ipilimumab plus nivolumab in the metastatic setting with SD or PR for at least 12 weeks on maintenance anti-PD1
Have a performance status of 0, 1 or 2 on the ECOG Performance Scale
Have a baseline HbA1c 6.4
Demonstrate adequate organ function. All screening labs should be performed within 14 days of treatment initiation
Absolute neutrophil count (ANC) 1,500 /mcL
Platelets 100,000 / mcL
Hemoglobin 9 g/dL or 5.6 mmol/L without transfusion or EPO dependency (within 7 days of assessment)
Serum creatinine OR Measured or calculateda creatinine clearance 1.5 X upper limit of normal (ULN) (GFR can also be used in place of creatinine or CrCl 60 mL/min for subject with creatinine levels > 1.5 X institutional ULN)
Serum total bilirubin 1.5 X ULN OR Direct bilirubin ULN for subjects with total bilirubin levels > 1.5 ULN
AST (SGOT) and ALT (SGPT) 2.5 X ULN OR 5 X ULN for subjects with liver metastases
Albumin >2.5 mg/dL
International Normalized Ratio (INR) or Prothrombin Time (PT) 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants; Activated Partial Thromboplastin Time (aPTT) 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
Patients must be free of active brain metastases by contrast-enhanced CT/MRI scans within 2 weeks prior to starting the study drugs. If known to have prior brain metastases, must not have evidence of active (enlarging and/or symptomatic lesions) brain disease on MRI evaluation within 4 weeks from SRS or WBRT treatment
Patients who have received radiation may be enrolled if the treating physician determines that they have recovered from radiation and are not experiencing radiation related clinically significant adverse events
Female patients of child bearing potential must have a negative urine or serum pregnancy test within 7 days from the time of registration
Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year

Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
Has an active infection requiring systemic IV antibiotic therapy
