Predictive and investigative kidney toxicity and drug safety evaluation, in vitro
Drug-induced nephrotoxicity is one of the leading causes of drug failure as the prediction of kidney toxicity during new drug development remains inaccurate. Early detection of in vitro nephrotoxicity is key to reducing both costs and timelines of drug development. Nephrotoxicity assays, which evaluate kidney toxicity using human-relevant models, provide essential data and insights to improve drug safety. The FDA recommends in vitro nephrotoxicity assessment of new drugs and biologics prior to in vivo assessments in animal models. Newcells kidney in vitro nephrotoxicity assays allow researchers to better predict renal safety profiles earlier in the drug development process.
Additional regulatory guidance from both the FDA and EMA also recommends the detection of early markers of kidney toxicity such as KIM-1, NGAL and clusterin, which can only be quantified in more complex in vitro kidney microtissue models. Such models are therefore needed for reliable predictive and early evaluation of renal safety profiles. Newcells aProximate™ proximal tubule cell model is an advanced microtissue model containing all relevant biomarkers and is designed to assess renal toxicity with unparalleled accuracy. It enables detection of early and late toxic effects, fulfilling a critical need in the field of in vitro nephrotoxicity assessment, through detection of early nephrotoxic markers and transporter activity.
The BASIC Nephrotoxicity study rapidly assesses renal toxicity in human, mouse, rat or dog through quantification of cellular viability (ATP and LDH levels) and trans-epithelial electrical resistance (TEER).
The COMPREHENSIVE Nephrotoxicity study is an in-depth assessment of renal toxicity in human, mouse, rat or dog. This study also includes quantification of FDA-approved kidney injury markers NGAL, KIM1 and Clusterin, ensuring your IND submissions will be further strengthened by the testing of parameters and biomarkers that follow regulatory guidelines.
Gene analysis, inhibitor study and species comparison (human, mouse, rat and dog) are available as insightful complements.
