QC and Stability Testing

Companies rely on our Quality Control testing services for their clinical phase vaccines and biologics. cGMP studies are conducted following FDA and EMA guidelines.

Clinical Drug Substance/Product Analysis

We support you to confidently release your clinical product by executing validated assays which form the backbone of your product monograph or IND CMC section, and establish the quality, efficacy and safety of your product.

Our technologies allow complete analysis of bulk drug substance and liquid or lyophilized drug product, and the validated analytical methods are performed under rigorous quality oversight, following defined standard operating procedures.

Your data integrity is assured and your results are handled securely.

GC-MS (vials)

Clinical Drug Substance/Product Stability

We help you build a stability plan that captures the essential storage-dependent characteristics of your product to verify quality, efficacy and safety are maintained and providing critical shelf-life determination data.

The curated selection of stability-indicating assays are implemented at the defined time-points, and validated storage conditions are employed. Be assured that your stability assays are never considered routine by our diligent scientific team.
