1.Primary Outcome
Title Change From Baseline in Total Body Fat Mass by Dual Energy X-ray Absorptiometry (DXA) at Week 48
Hide Description Dual energy X-ray absorptiometry (DXA) was used to assess changes in body composition, including total fat and lean body mass (FM and LBM) and appendicular skeletal fat and muscle mass (aFM and aLBM). DXA instruments had a source that generated x-rays split into two energies which measured bone mineral mass and soft tissue from which fat and fat-free mass (or lean body mass) were estimated.

Title Change From Baseline in HbA1c at Week 24 and 48
Hide Description HbA1c reflects average glucose concentrations over the past 3 months and therefore provides a useful index of the glycemic control of bimagrumab over that time period. It is a standard endpoint used to assess the glycemic efficacy of any anti-diabetic medication. HbA1c is a key glycemic parameter which correlates with reduction of risk of diabetic complications.

Title Change From Baseline in Lean Body Mass (LBM) Measured by DXA
Hide Description

Lean body mass (LBM) is a part of body composition defined as the difference between total body weight and body fat weight. This means that it counts the mass of all organs except body fat, including bones, muscles, blood, skin, and everything else.

Dual energy X-ray absorptiometry (DXA) was used to assess changes in body composition, including total fat and lean body mass (FM and LBM) and appendicular skeletal fat and muscle mass (aFM and aLBM). DXA instruments had a source that generated x-rays split into two energies which measured bone mineral mass and soft tissue from which fat and fat-free mass (or lean body mass) were estimated.

Title Change From Baseline in Insulin Resistance (HOMA2-IR)
Hide Description Blood samples were collected to analyze insulin resistance. The homeostasis model assessment computational method was used to estimate insulin resistance (HOMA2-IR) from fasting plasma glucose and insulin. The HOMA2-IR is the reciprocal of insulin sensitivity (%S), as a percentage of a normal reference population (normal young adult). Higher numbers indicate higher insulin resistance. No established cutoffs are indicating impaired resistance. HOMA2-IR was calculated using an online calculator [https://www.dtu.ox.ac.uk/homacalculator/].
