CD Formulation is dedicated to ensuring the safety of nucleic acid drugs, particularly in terms of their potential effects on reproductive toxicity. We provide extensive reproductive toxicity study services, offering high-precision toxicity evaluations through scientifically stringent experimental methodologies and cutting-edge technical assistance. Our commitment is to aid clients in speeding up the development of safe and dependable drugs.
Reproductive toxicity studies are a crucial part of evaluating the effects of compounds on the reproductive function and development processes of mammals through animal experiments. In the development of nucleic acid drugs, these studies hold great promise for predicting potential adverse effects on reproductive cells, the conception process, embryonic development, and even the growth of offspring. As nucleic acid drugs make breakthroughs in the medical field, these multi-layered toxicity evaluations lay a safe foundation for the clinical application of new drugs.
CD Formulation, with many years of experience in toxicological research, provides accurate and stable reproductive toxicity assessments for clients at home and abroad with a professional technical team and internationally standardized laboratory environment.
In this phase, we carefully design drug administration to experimental animals before mating to thoroughly investigate the potential impacts of drugs on reproductive cells. By assessing conception ability and the health status of the reproductive system, we explore whether the drug poses long-term impacts on the development of offspring.
Teratogenic sensitivity studies aim to use precise administration strategies during critical stages of organogenesis to evaluate potential embryotoxicity of drugs on embryos. Using advanced imaging and biological testing tools, we identify possible structural deformities or functional abnormalities to ensure the safety of new drug development.
Focusing on dosing schemes around the perinatal and lactation periods, we assess the sustained impact of drugs on maternal health and the development of the new generation. Through detailed behavioral and physiological tests, we ensure comprehensive understanding of the possible changes in reproductive capacity at different growth stages caused by the drug.
Combining specific customer needs, we provide customized study plans for nucleic acid drugs to ensure that testing processes and research data are highly relevant. Through personalized services and scientific support, we help clients obtain targeted and practical research conclusions.
Items | Descriptions |
---|---|
Animal Selection | Young, sexually mature, unbred adult animals, usually rodent rats, are generally selected, and their initial body weight should not fluctuate more than 20% from the mean range. |
Dose Design | Administered once a day with at least three dose groups to establish a dose-response relationship, with doses chosen from ranges similar to repeated-dose toxicity studies. |
Route of Administration | It is generally recommended to be consistent with the clinically intended route; if multiple routes exist, choose the one with higher exposure unless tests show no significant difference in pharmacokinetics between routes. |
Drugs are administered subcutaneously according to set dose groups, observing the effects of each dose on biological markers.
Administer drugs 60 days before mating for male rats, 14 days before mating, and 20 days after pregnancy for female rats to ensure comprehensive evaluation of reproductive and developmental functions.

Through an in-depth preliminary planning stage, we work closely with customers to fully understand research goals and specific needs.
After confirming the experimental design, we fully prepare the experimental conditions, from regulating the experimental environment to calibrating trial equipment and preparing materials, ensuring the experiment is conducted under highly controlled conditions.
During the experiment, we use professional technical equipment for precise data collection and conduct in-depth data analysis using complex analytical tools.
After the experimental phase is completed, we compile a detailed experimental report covering all research methods, data results, and analysis discussions.
Technology: Developmental toxicity testing utilizing an in vitro modeling platform

The authors describe the development of in vitro models of human development that could conceivably be applied to developmental toxicity testing. To date, these regulatory assessments have been conducted in animal experiments, and their relevance to adverse reactions in humans may be questioned. However, recently developed cell culture-based embryo-fetal developmental models have not demonstrated sufficient standardization and reproducibility. This paper explores the strengths and weaknesses of in vivo and in vitro developmental toxicity testing and the possibility of using a combination of testing strategies as a viable option in the near future.
