Brief summary
Alpha-melanocyte stimulatory hormone (α-MSH) is a melanocyte-stimulating hormone produced by the hypothalamus and released from the pituitary gland. It acts as an agonist to the melanocortin 5 receptor (MC5R) in human skeletal muscle, playing a role in glucose uptake and disposal. This study aims to investigate whether α-MSH can enhance glucose tolerance in patients with Type 2 Diabetes Mellitus (T2DM).
Detailed description
Pre-clinical studies in mice have shown improved glucose clearance with α-MSH infusion, particularly in skeletal muscle. Research has demonstrated that α-MSH improves glucose tolerance in healthy humans by promoting glucose uptake in skeletal muscle cells. Therefore this study seeks to answer the question of whether alpha-MSH improves glucose tolerance in patients with T2DM. This will be addressed through measuring the impact of α-MSH infusion in patients with T2DM. The research involves a double-blinded, randomized, placebo-controlled crossover study.
Interventions
Pharmaceutical grade α-MSH is custom synthesized to GMP standards by Auspep (Australia www.auspep.com.au), a good manufacturing practice (GMP) accredited manufacturer of peptides, approved by the Therapeutic Goods Administration (TGA), European Medicines Agency (EMA) and U.S. Food and Drug Administration (FDA).
Pharmaceutical GMP-grade sterile 0.5% human albumin dissolved in saline.
