A Study of Empagliflozin in Patients With Refractory Diabetes Mellitus With Insulin Resistance

A Multicenter, Open-label, Single-arm Study With Regard to the Efficacy and Safety of Empagliflozin in Patients With Refractory Diabetes Mellitus With Insulin Resistance

A multicenter, open-label, single-arm study with regard to the efficacy and safety of empagliflozin in patients with refractory diabetes mellitus with insulin resistance

To evaluate the clinical efficacy of a treatment with empagliflozin in refractory diabetes mellitus patients with insulin resistance (insulin resistance syndrome, lipoatrophic diabetes mellitus) by using the HbA1c change at Week 24 of treatment from baseline

• 3) A patient with >= 7.0 % of HbA1c at the time of screening
• 4) A patient, if taking other SGLT2 inhibitor than empagliflozin, whose SGLT2 inhibitor can be washed out for more than 12 weeks prior to starting empagliflozin
• 5) A patient at the age of >=20 years at the time of consent
• 6) A patient who has received sufficient explanation with regard to information such as the objectives and details of this study, expected drug efficacy/pharmacological action, and risks, and has given written consent by her/himself.

• 2) A patient with suspected hepatic dysfunction, that either of serum ALT, AST or alkaline phosphatase in the screening period is exceeding 3-fold of upper limit of normal rang
• 3) A patient who is receiving a systemic steroid at the time of consent (except for type B)
• 4) A patient whose thyroid hormone product dose has been changed within 6 weeks before obtaining consent
• 5) A patient with unstable endocrine diseases other than diabetes mellitus
• 6) A patient with hemolysis or blood diseases that destabilize erythrocytic cells and other various disorders (e.g., malaria, babesiosis, hemolytic anemia).
• 7) A premenopausal female patient (the latest menstruation was within 1 year before obtaining consent), a lactating or pregnant patient, or a patient who may be pregnant (without hysterectomy or ovariectomy) who has no intention to use efficacious contraception defined in this study during the treatment period and would not agree to receive regular pregnancy tests during the treatment period

• 9) A patient who is in the condition that makes it difficult to administer the study drug
• 10) A patient with renal dysfunction of eGFR (MDRD calculating formula) < 45 mL/min/1.73 m2 in the screening period
• 11) A patient who indicates a hypersensitivity response to empagliflozin or its excipients, or a patient with lactose-intolerance
• 12) A patient with severe ketosis, diabetic coma or precoma, severe infection, perioperative status, or serious trauma
