Challenges: Stability, Cost, and Market Access
Customized peptide drug development has accelerated rapidly, addressing a range of therapeutic needs; however, the sector continues to encounter several key challenges in 2025, particularly regarding peptide stability, manufacturing costs, and market access.
One of the primary technical hurdles is peptide stability. Peptides are inherently susceptible to enzymatic degradation and rapid renal clearance, which can limit their bioavailability and therapeutic efficacy. Efforts to improve stability include chemical modifications such as cyclization, incorporation of D-amino acids, and conjugation to polyethylene glycol (PEGylation). For instance, Bachem, a leading peptide manufacturer, continues to advance formulations that enhance peptide half-life and resistance to proteolytic cleavage, essential for chronic disease indications.
Cost remains a significant barrier, particularly for highly customized or complex peptides. The multi-step synthesis and purification processes required for sequence-specific peptides can be resource-intensive, and yields may decrease as sequence length and complexity increase. Innovations in solid-phase peptide synthesis (SPPS) and process automation, as seen in the technologies provided by CordenPharma and Polypeptide Group, are vital to reducing cost per batch and improving scalability. Nevertheless, as personalized medicine demands increase, balancing customization with economic feasibility remains an ongoing concern.
Market access poses additional challenges, especially given the regulatory complexities surrounding novel peptide therapeutics. Customized peptides often fall outside traditional regulatory pathways, requiring extensive characterization and safety validation. Both the U.S. Food and Drug Administration and the European Medicines Agency have published evolving guidance on peptide drugs, but regulatory harmonization and streamlined approval processes for highly tailored peptides remain limited. This can delay patient access and increase development timelines.
Looking ahead, the next few years are expected to see advances in peptide engineering—such as stapled and self-assembling peptides—and further automation of synthesis, which should help address some stability and cost issues. Industry stakeholders are also collaborating with regulatory agencies to clarify guidelines and accelerate clinical translation. Despite these efforts, the path to widespread adoption of customized peptide drugs in the clinic will depend on continued innovation in both technical and regulatory domains.
Future Outlook: Next-Gen Peptides and Market Opportunities to 2030
