Still, Pfizer has other experimental extreme weight medicines in its pipe to start with of progress that present as much as operate in numerous methods from its now-discontinued therapies. That consists of a dental medication that obstructs yet one more digestive tract hormonal agent referred to as GIPR, which went into stage 2 assessments in 2015, and an added once-daily dental GLP-1 in stage one assessments.
Pfizer thinks a medication concentrating on GIPR could be a lot extra dependable and far simpler for folks to endure, earlier Chief Scientific Officer Mikael Dolsten, that has often because left the agency, knowledgeable capitalists inOctober He included that “there are so many applications for GLP-1s.”
Pfizer’s danuglipron advertises weight-loss by concentrating on GLP-1, which is likewise precisely how Novo Nordisk’s weight-loss shot Wegovy and diabetic points remedy Ozempic job. Eli Lilly’s weight-loss shot Zepbound and diabetic points shot Mounjaro goal GLP-1 but likewise set off yet one more digestive tract hormonal agent referred to as GIP.
The simply dental GLP-1 licensed by the Food and Drug Administration till now’s Novo Nordisk’s Rybelsus, which offers with Type 2 diabetic points and generated round $3.38 billion in sales in 2024.
