Developmental and Reproductive Toxicology
Developmental and Reproductive Toxicology (DART) studies are an essential component of safety assessments for pharmaceuticals and chemicals (ICH M3, S5, S6; OECD 421, 422, 443, 414, 415, 416). Our DART department boasts extensive experience and can provide clients with a comprehensive suite of reproductive and developmental toxicity tests that comply with the guidelines set forth by the U.S. FDA, U.S. EPA, ICH, OECD, and CFDA. All tests are conducted in strict adherence to international GLP regulatory standards. Our years of accumulated historical control databases, a stable technical team, and highly qualified senior researchers ensure that we can deliver high-quality services to our clients promptly and efficiently.
The safety tests for pharmaceutical formulations primarily include irritation, sensitization, and hemolytic tests. These tests evaluate the toxicity—such as local irritation and local allergic reactions—that may occur at the site of administration when a drug formulation is administered via non-oral routes, including through the skin, mucous membranes, body cavities, and blood vessels, as well as any systemic toxicity—such as systemic allergic reactions and hemolysis—that may arise from systemic exposure. These tests are an integral part of preclinical safety evaluation.
We have an experienced team of toxicology specialists and a team of highly qualified experts—both domestic and international—who can provide clients with scientifically sound study designs and dose selections to ensure the smooth conduct of toxicology studies. Our general toxicology studies comply with international GLP regulatory standards, and our study designs meet the requirements of relevant guidelines issued by the NMPA (CFDA), U.S. FDA, OECD, and ICH, enabling us to satisfy the requirements for clinical trial applications or market approvals in various countries and regions.
Early Toxicity Prediction and Screening
Drug safety issues are a major factor contributing to drug development failures and one of the primary reasons for withdrawing marketed drugs from the market. Traditionally, toxicity testing and safety evaluations of drugs have been conducted during the non-clinical phase through animal studies. Once serious toxic reactions are identified, leading to development failures, this can result in substantial economic losses. Conducting ion channel and cell-level toxicity tests early in the drug development process can significantly reduce the likelihood of later-stage development failures, thereby increasing the success rate of drug development and lowering R&D costs.
