Outcomes
Primary Outcome Measures
Number of Participants That Completed All Telemedicine Visits
Feasibility will be defined as completion of all telemedicine visits by > 2/3 of enrolled patients (unless treatment discontinued early for toxicity or disease progression).
Secondary Outcome Measures
Percentage of Participants With Stable PSA Levels at 6 Months as Defined by a <20% Change
Percent of patients with 6-month PSA stable 20% change at 6 months as compared to baseline
Adherence With Metformin as Measured by Electronic Pill Adherence Monitoring
Adherence with metformin as measured by electronic pill adherence monitoring. Patients were provided with an electronic medication dispenser/medication adherence monitoring device. The device provided audible and visual reminders to proceed with drug dosing and was equipped with a cellular modem that registers a signal to a cloud-based database each time a patient accessed his or her study medication. However, the size and shape of the metformin pills caused the device to malfunction frequently, which led patients to access the pills from the device manually; the data, therefore, could not be used for analysis.

5. Study Description
Brief Summary
Clinical trials are critical to informing the care of patients with cancer. However, only 3-5% of patients with cancer enroll in clinical trials. Poor accrual to trials has major implications with regards to the pace of progress, the cost of clinical cancer research, and the generalizability of results. The investigators have recently shown in an analysis of 7,776 cancer clinical trials registered on clinicaltrials.gov that approximately 20% of cancer clinical trials fail to complete enrollment at all; the most often cited reason was poor accrual.
Prior research has identified barriers to cancer clinical trial accrual that can be generally categorized in the domains of availability, awareness, and acceptance. Much attention has been paid to the barriers involvement awareness and acceptance - however, trial availability is likely a "rate limiting step". This pilot study is the first in a series of planned steps to attempt to shift the current paradigm of "bringing patients to trials" to "bringing trials to patients." With the integration of telemedicine visits, the investigators aim to decrease the burden of participation for patients, begin to address geographic barriers, and ultimately improve trial accrual. In this study, men with biochemically recurrent prostate cancer (a rising PSA after definitive local therapy) will receive the antidiabetic drug, metformin. Patients will require a single on-site visit for study enrollment. The remainder of the 6 month study will be conducted via a HIPPA secure telemonitoring system (monthly visits conducted via telemedicine with tablet computers provided to each patients).
Detailed Description
Men with an isolated PSA recurrence after local therapy are an ideal population for the evaluation of novel therapies given the minimal disease burden, generally indolent natural history, and patients' preference to avoid the adverse effects of androgen deprivation therapy. Metformin has shown anti-prostate cancer activity in preclinical models and cohort studies. Metformin, a biguanide oral antihyperglycemic agent, abrogates hyperinsulinemia in individuals with and without diabetes and has shown promising anti-prostate cancer activity in preclinical models, epidemiologic studies, and retrospective cohorts. Several epidemiologic/retrospective studies have shown that metformin has a positive impact on overall survival among men with prostate cancer.
These nonclinical and clinical studies have led to calls for prospective studies of metformin in patients with prostate cancer. This is a pilot telemedicine study of metformin in patients with a rising PSA ("biochemical recurrence") after definitive local therapy for prostate cancer.
The current study is supported by the following rationale:
A large proportion of clinical trials close prematurely due to poor accrual.
Geographic inaccessibility is a barrier to clinical trial participation.
Metformin is a safe and inexpensive medication that has demonstrated anti-prostate cancer activity in nonclinical and epidemiologic studies. Importantly, metformin has been shown to be safe in non-diabetic patients (e.g., patients with polycystic ovary disease) and does not cause hypoglycemia.
Use of novel technologies may facilitate clinical trial accrual and minimize the burden of participation for patients. Ultimately, these approaches may also decrease the cost of drug development and increase the pace of progress.
In the absence of prohibitive toxicities or disease progression (defined in 4.4), patients may continue treatment for the 6-month study period. This study will include a baseline visit for study enrollment at Mount Sinai. The remainder of the visits will be telemedicine visits conducted using secure video conferencing.
