topical lingual leptin

Topical lingual leptin is an investigational formulation of the hormone leptin designed for delivery via the tongue (lingual) or oral mucosa, rather than by injection. This approach leverages a newly discovered biological pathway—the "tongue-brain connection"—to activate satiety centers in the brain without systemic exposure, aiming to reduce risks and side effects associated with systemically delivered therapeutics. Leptin is a hormone produced by adipose tissue that signals satiety to the hypothalamus, thereby regulating appetite and energy expenditure. Traditional recombinant leptin therapies have been used primarily for rare conditions like congenital or acquired lipodystrophy but have shown limited efficacy in common obesity due to issues such as leptin resistance. The topical lingual approach seeks to bypass these limitations by directly stimulating neural pathways from the tongue to the brain involved in appetite regulation. Gila Therapeutics is developing this modality as part of its pipeline targeting obesity and metabolic disorders[1].
