Switzerland-based Aphaia Pharma AG has started a second Phase 2 trial of a new oral candidate drug for obesity which aims to restore endogenous endocrine balance in individuals with the disorder. The drug is a coated formulation of glucose, which is included on the World Health Organization’s list of essential medicines. It is designed to be released in the small intestine to restore endogenous nutrient-sensing signalling pathways and stimulate the release of hormones that control multiple functions including appetite, hunger, satiety and glucose metabolism.
