The protein and peptide therapeutics market: sizing the next decade.
Quietly, one of pharma's most consequential categories has become its biggest growth engine. A look at the numbers behind protein and peptide therapeutics, and who is building the moat.
Protein and peptide therapeutics — insulins, GLP-1s, monoclonal antibodies, hormone analogues, oncology biologics — have moved from a specialist corner of the drug industry to its commercial centre of gravity. The category now sits behind some of the largest individual products in the world, with GLP-1 receptor agonists alone reshaping the obesity and diabetes franchises of multiple top-twenty pharma names.
What makes the category investable from a research standpoint is its combination of large existing scale, double-digit growth, and a small, identifiable group of incumbents with both the manufacturing capability and the regulatory infrastructure to defend their position. Most of the value continues to accrue to a familiar set of names.
