Pre-Clinical Services

DMPK

Our scientists at Vipragen design and conduct PK studies to examine multiple parameters in support of regulatory submissions with a range of analytical support, including LC-MS/MS, HPLC, CE or immunochemistry. Toxicokinetic assessments are conducted with ongoing toxicology programs and in compliance with GLP requirements.

In Vitro ADME

In Vitro ADME assays are an important part of a successful drug development program aiding in the critical decision-making process by offering metabolic information about drug-drug interactions, pharmacokinetics, absorption and potential toxicities. Our wide range of in vitro assays performed under GLP conditions, yield information in the areas of metabolism, toxicity and physicochemical characteristics of your product.
