Efficacy of Exenatide-LAR Alone and in Combination With Dapagliflozin in Overweight/Obese, Insulin Treated Patients With Uncontrolled Type 2 Diabetes

The purpose of this study is to see what the effects of using one or two additional diabetes
drugs (dapagliflozin and exenatide-LAR) are on blood sugar levels in patients who are taking
insulin. This research study is being done because investigators do not know which of these
commonly-used medications, medication combinations or increasing insulin dose is better.

This is a single center prospective, randomized, placebo-controlled trial in
overweight/obese patients with insulin treated uncontrolled type 2 diabetes

Eligible subjects willing to participate in the study will be randomized to one of 3
treatment groups:

Group 1: Insulin titration + behavioral therapy Basal insulin titration upto 12 weeks with 2
U increment every 3 days (Fasting glucose goal <110) based on self-monitored blood glucose.

After 12 weeks, patients with HbA1c >8% will switch to a basal bolus regimen. Basal insulin
dose will be reduced by one-third or one-half at the investigator's discretion and replaced
with 3 doses of prandial insulin(lispro/novorapid) to maintain the same total insulin dose.
Thereafter, basal insulin will be titrated as before and prandial insulin titration will be
based on self-monitored pre-meal glucose.

Group 2: Exenatide-LAR 2mg q week x 24 weeks + Dapagliflozin placebo x 52 weeks + behavioral
therapy. Daily insulin dose will be reduced by 20%.

Group 3: Exenatide-LAR 2mg q week x 24 weeks plus Dapagliflozin 5mg QD x 2 weeks followed by
10mg QD x22 weeks + behavioral therapy. Daily insulin dose will be reduced by 20%.

Behavioral therapy will be delivered by registered dietitians and will include the BMIQ
program -a web based medical weight loss program designed by Dr Aronne.

All procedures in the study are standard of care except DEXA and blood biomarkers which will
be done for research purposes. Further details of the study design and procedures are in the
attached protocol.
