Drug efficacy study is the first step in new drug development. The result of  the druggability study determines whether the new compound (or Chinese medicine prescription) is suitable for clinical trials. The design level of major efficacy studies depends on whether the new drug is justifiable.

Boji has been engaged in new drug research and development for nearly two decades. Boji has a professional research team in efficacy study and drug screening. Five major efficacy evaluation and screening platforms have been established for anti-tumor drugs, cardiovascular and cerebrovascular drugs, endocrine and metabolic drugs, nervous system drugs and external preparations (including nebulized inhalation preparations). In addition, the team members also have research experience in the diseases of the digestive system, respiratory system, bone joint system, urogenital system and other diseases.

Boji always adheres to the new drug evaluation concept of "quality management and academic emphasis", and continuously strengthens the construction and implementation of quality management systems. At the same time, Boji pays attention to academic research, exploring new methods of animal models and seeking ways to control the quality of experiments. Boji will regularly provide research and management personnel the opportunity to participate in internal and external trainings, continuously improve professionalsm and strive to provide customers with more professional R & D services.

Five pharmacodynamics test platforms

Anti-tumordrug development platform



In vitro anti-tumor test

This platform can perform in vitro activity measurement of tumors such as lung cancer, liver cancer, stomach cancer, colon cancer, breast cancer, pancreatic cancer, ovarian cancer and leukemia.

In vivo anti-tumor test

The CDX model is the most commonly used method for screening anti-tumor drugs. In addition to conducting research on solid tumors and ascites tumors in nude mice or ordinary mice, this platform also conducts observation of life-cycle tests of tumor-bearing mice and explores new treatment options for tumors. The center is building a PDX model platform and plans to find biomarkers, distinguish treatment-sensitive patient groups, accelerate the drug development process and improve the success rate of drug clinical trials. The platform provides technical services for bone cancer, lung cancer and gynecological cancer.
