Biomarker Solutions for Biotherapeutics

Inotiv has extensive experience designing preclinical and clinical biomarker strategies to support our clients’ broader clinical development objectives. Working collaboratively with you, we focus on carefully selecting biomarkers to deliver results that support your decision making and produce a significant return on investment.

Our specialized biomarker services include:

• Advice on the optimal selection of biomarkers in the context of your drug candidate, target disease, and project budget
• Development, optimization, and validation of biomarker assays across a wide range of matrices and technology platforms
• Biomarker analysis of preclinical and clinical samples for exploratory or clinical trial settings
• Explanation/interpretation of results and advice on key outcomes and decisions to be made about candidate therapies

Our biomarker strategies encompass the full biological spectrum, including DNA, RNA, protein, cell, and tissue analysis, matched with proven and trusted technology platforms:

Inotiv’s flow cytometry expertise will provide the data needed to get your therapeutic to market faster and provide patients with the treatment they deserve. We specialize in customized flow cytometry panels in early-phase preclinical and clinical trial research and are equipped to process samples from a wide range of matrices, from fresh to cryopreserved.

We analyze samples using a variety of sophisticated approaches, including multimer, phospho-flow cytometry, and receptor occupancy (RO) assays. We utilize dedicated peripheral blood mononuclear cell (PBMC) processing units that are linked to biosafety level 2 (BSL2) cell culture laboratories.
