SUPPRESSING DIABETES
Type 1 diabetes (T1DM) is caused by,insulin deficiency PLUS glucagon excess, but
only the former is treated.
We propose to treat the other half of thedisorder, the glucagon excess to reduce will eliminate
glucose volatility and its clinical consequences.

• Characterized by loss of adipose (fat) tissue
• Concomitant deficiency of leptin (fat-cell hormone)
• Accumulation of excess fat in blood, liver, muscle
• Patients typically affected in childhood or adolescence
Rare and severe metabolic/endocrine disorder
• Severe insulin resistance
• Diabetes, often uncontrolled by current medications
• Severe hypertriglyceridemia (high levels of triglycerides in the bloodstream)
• Excess fat accumulation in the liver
• Multiple other co-morbidities
Often severe metabolic abnormalities
• No therapies indicated specifically for the treatment of the metabolic abnormalities associated with lipodystrophy
Large unmet medical need
Prevalence: ~ a few thousand patients worldwide

Safety observationsSafety observations
Adverse events were generally consistent with known co-morbid conditions of lipodystrophy (pancreatitis, proteinuria, autoimmune/chronic hepatitis) or expected pharmacological effects of metreleptin (weight loss or insulin-induced hypoglycemia in the setting of improved insulin sensitivity)

*In NHANES, “chronic kidney disease" refers to people with microalbuminuria (albumin:creatinine ratio >30 µg/mg).†In the NHANES analysis, "foot problems" includes foot/toe amputations, foot lesions, and numbness in the feet.‡"Eye damage" includes a positive response by NHANES participants to the question, "Have you been told diabetes has affected your eyes/had retinopathy?" Retinopathy is damage to the eye's retina. In NHANES, people without diagnosed diabetes were not asked this question, therefore, prevalence information for nondiabetics is not available.

How Can Diabetes Be Prevented?
People with pre-diabetes should modify
lifestyle, including
Lose 5-10% of body weight if
overweight or obese
Moderate physical activity (e.g.,
walking) at least 150 min/week Medications- metformin, precose and perhaps
thiazolidinediones (TZDs)- should be considered

Surgery for Obesity in Patients with T2DM
• BMI > 30 kg/m2
− laparoscopic-assisted gastric banding in or Roux-en-Y gastric bypass – As approved by FDA
• BMI > 35 kg/m2
− Roux-en-Y gastric bypass to achieve at least short-term weight reduction Patients with T2DM who undergo Roux-en-Y gastric
bypass must have meticulous metabolic postoperative follow-up because of a risk of vitamin and mineral deficiencies and hypoglycemia
