Our Preclinical Offering
LNPs are essential to ensure safe and efficient nucleic acid delivery to cells. These particles, typically composed of four different lipids, provide a protective bubble for the delicate nucleic acid molecules. As part of our LNP CDMO services capabilities, the Early Formulation Screening Service encompasses a best-in-class expert team that is dedicated to screening and optimizing LNP formulations for your nucleic acid payloads.
Screening of ionizable lipids and of appropriate lipid compositions that provide effective results, functionalization of LNPs with targeting ligands, scale up of lead candidates, development of advanced characterization techniques, or long-term stabilization, are only a few examples of technical challenges that we, as experts in the field, tackle for you.

Formulation Screening
Ionizable lipids are essential excipients driving the success of LNP delivery systems. Our carefully curated portfolio of ionizable lipids from multiple independent libraries encompasses a diverse chemical design space, demonstrating a proven track record of success across various applications. We identify the most promising lead lipids for your payloads, complemented by comprehensive analytical characterization including advanced in vitro testing.

Formulation Optimization
We refine the formulation composition and perfect the lead mixture for maximal/optimal efficacy and in vivo tropism. Our advanced analytical characterization includes extensive in vitro and in vivo studies, as well as lipidomics analysis, enabling accurate predictions of biological behavior.

Preclinical Scale-Up
To prepare your formulation for clinical development, we focus on finding optimal manufacturing conditions and transition bench-scale unit operations to their scalable counterparts. Additionally, we offer long-term stability studies and lyophilization development. When the formulation is ready to progress to the clinical phase, our experts ensure a seamless technology transfer to our in-house GMP manufacturing site.
As an experienced CDMO partner, you can rely on us to facilitate seamless technology transfers, robust process optimization, and scalable manufacturing to bridge the gap from discovery to clinical application. Our Indianapolis Center of Excellence has a worldwide reputation in contract manufacturing and fill and finish services for emerging biotech through established pharmaceutical companies. The site has manufactured a wide range of sterile, complex drug products including LNPs, liposomes and PEGylated formulations.
