Case Study: Integrated CMC Solution for IND Application in 9 Months

We supported the 30+ AA macrocyclic peptide project by providing integrated CMC services, including API process development, manufacturing, formulation development, and CMC writing. We successfully completed the IND application within nine months, overcoming the challenges of an original route yield of less than 1% and a limited supply of a special building block for conjugation.

In the end, we developed a new route based on SPPS, and synthesize the main-chain and side-chain in parallel; we further achieved cyclization on resin, and completed the API synthesis via solid phase coupling strategy, which increased the yield by fourfold. The conjugation process was optimized to facilitate Tox and GMP batches in a more efficient manner. In-parallel and seamless workstreams allowed the entire project to be completed in nine months.

Manufacturing

With our global standard quality system, we are well positioned to be your strategic manufacturing partner for reliable and robust supplies of your peptide APIs, from gram to metric ton scales.

Our custom synthesizers and cleavage systems are designed to minimize risks of both microbial contamination and cross-contamination. Our peptide platform ensures knowledge retention and scale-up throughout your product life cycle, while expediting your development through seamless collaboration among different functional teams.

At our Changzhou and Taixing sites in China, we have over 20 Solid Phase Peptide Synthesis (SPPS) production lines with a wide range of synthesizers from 20 L to 5,000 L. T he total reactor volume for SPPS is over 100,000 L. And we are still expanding our SPPS capacity at Taixing and Singapore sites in the next few years.

Our peptide manufacturing platform is also equipped with the latest technologies, including Liquid Phase Peptide Synthesis (LPPS), reactor-in-series (with PAT data collection), continues flow chromatography, Tangential Flow Filtration (TFF) / precipitation, etc.
