Xyzagen (ZiZaGen) is seeking a highly skilled scientist with a background in Pharmaceutical Sciences to be Associate Director of Clinical Pharmacology. This role is designed for a professional who will lead the design, execution, and interpretation of clinical pharmacology studies (Phase I–III), develop and implement quantitative pharmacometric strategies to support dose selection and regulatory submissions. This position can either have experience in clinical development of biologics or small molecules. If the individual has experience in small molecule drug development then they should also be experienced in in vitro ADME studies. This position would lead our in vitro ADME solutions internally, and provide strategic drug development and regulatory consulting to a diverse client base ranging from NIH-funded startups to mid-sized pharmaceutical companies in small and large molecules. If the individual has large molecule experience then they should be experienced in large molecule bioanalytical assay development and validation for PK and ADA assays.

Xyzagen is a contract research lab supporting pharmacokinetics, ADME, in vivo PK, small and large molecule bioanalytical, pharmacology, and non-GLP safety assessments. We are also a drug development consultancy providing regulatory advice to clients across nonclinical and clinical disciplines. At Xyzagen, we accelerate medicines to patients by partnering with life science innovators, contributing to multiple FDA submissions and approvals since 2018. Xyzagen has provided strategic advice to early NIH funded biotechs, small and mid-size pharma and venture capital firms. At Xyzagen, we accelerate medicines to patients by partnering with life science innovators. Since 2018, we have worked with over 100 different innovators worldwide and have helped in the approval of multiple new therapeutics by the FDA. Xyzagen also conducts its own research on Kv7 channel openers within the therapeutic areas of Neurology, Seizures and Pain.

Why Join Xyzagen?

• Rapid execution of nonclinical pharmacokinetic and safety studies
