Clinical Trial Summary

This will be a placebo-controlled, randomized, double blind, crossover study with a 4 week wash out period. Collect pilot data on the safety, tolerability, and feasibility of empagliflozin therapy in overweight/obese patients with CFRD to support a future larger randomized controlled trial.

Description:

The overall goal of this proposal is to collect pilot data for safety and feasibility metrics to support a future larger randomized controlled trial. In this study, we will examine the safety and tolerability of Sodium glucose co-transporter 2 inhibitor (SGLT2i) empagliflozin as an add-on therapy to insulin for overweight/obese adult patients with CFRD. We hypothesize that empagliflozin will be safe, well tolerated and will improve glycemic control in overweight/obese adult patients with CFRD. Specific Aim 1: Collect pilot data on the safety, tolerability, and feasibility of empagliflozin therapy in overweight/obese patients with CFRD to support a future larger randomized controlled trial. Hypothesis 1: Empagliflozin will be safe and well tolerated, with no evidence for electrolyte abnormalities, metabolic acidosis, ketosis or increased risk of severe hypoglycemia in overweight/obese adults people with CFRD. Specific Aim 2: Collect preliminary data to evaluate the effect of empagliflozin on glycemic outcomes. Hypothesis 2: Treatment with empagliflozin will improve glycemic control as indicated by glucose levels as measured by oral glucose tolerance test (OGTT), and on glycemic outcomes as measured by continuous glucose monitoring (CGM).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility, safety, tolerability	The primary outcomes are related to feasibility, including safety and treatment tolerability. Safety will be evaluated as the proportion (in %) of participants who experience a serious adverse event during the study. Tolerability will be evaluated as the proportion (in %) of participants who discontinue their assigned treatment due to side effects.	Duration of anticipated participation for an individual participant's would be around 15 weeks.Duration anticipated to complete all study procedures, including any long-term follow-up, and data analysis is 24 months.
