How Peptide Development Complexity Is Reshaping CDMO Partnerships

As peptide pipelines continue expanding globally, pharmaceutical companies are increasingly turning to CDMOs earlier in the lifecycle to help manage growing technical and operational complexity. Outsourcing partners are being leaned on to support process development, analytical strategy, scale-up, and regulatory readiness from the earliest stages of a program. At the same time, rising demand for peptide therapeutics is placing new pressure on manufacturing capacity, raw material availability, and technical expertise across the industry. 

In a recent episode of Off Script: A Pharma Manufacturing Podcast, we spoke with Dr. Sharadsrikar Venkatesan Kotturi, chief scientific officer at Neuland Laboratories, about how peptide development is reshaping relationships between sponsors and CDMOs. The conversation explores why pharmaceutical companies are engaging outsourcing partners earlier in the process, the growing execution challenges associated with peptide scale-up and impurity control, and how analytical complexity, raw material sourcing, and manufacturing scalability increasingly intersect across peptide programs. Kotturi also discusses the strain these shifting expectations are placing on both sponsors and service providers, along with the operational realities of supporting early-stage peptide development. 

In the second half of our conversation, Kotturi detailed the operational and technical realities shaping modern peptide manufacturing. He explained why long-chain and high-purity peptides are increasingly difficult to scale reproducibly, how aggregation, impurity control, and analytical sensitivity compound across larger sequences, and why process robustness ultimately determines whether peptide programs can succeed commercially. The discussion also covered the growing intersection between process design and supply chain resilience, including how early route selection decisions can amplify sourcing risk for protected amino acids and specialized reagents.
