CD Formulation is committed to exploring and researching the generic nanoformulation process, pharmaceutical quality, and therapeutic equivalence of generic nanoformulations and reference preparations, which has important reference significance for the research and development, large-scale production, and quality control of generic nanoformulations.
Generic nanoformulations are required to be both pharmaceutically and therapeutically equivalent to a reference listed drug (RLD). And Generic nanoformulation and RLD hold the same active ingredient(s), dosage form, route of administration, strength, labeling, and conditions of use, among other characteristics, and are equivalent in safety and therapy.
Currently, nanomedicines that have been approved and can be commercialized include lipid nanomedicines, polymer nanomedicines, nanocrystals, inorganic nanoparticles, and protein nanoparticles. Due the production process of nanoformulation is relatively complex, and it is difficult to break through the technical barriers of patent imitation, resulting in low reproducibility of related products and difficulty in ensuring quality. Therefore, to ensure the safety, effectiveness, and quality control of generic nanoformulation, it is necessary for us to quickly develop generic nanoformulations to reduce the cost of consumption for patients.
Nanoformulations use new excipients and their compositions are relatively complex. The composition and dosage of the excipients must not only be the same as the RLD, but the microstructure should also be consistent with RLD. The production process of nanoformulations is more complex and often requires the use of proprietary processes and equipment, and expansion of production scale can easily affect product quality. In addition, after nanoformulations enter the human body, they usually need to release drugs to exert their efficacy. So the rate and location of drug release in the body may affect clinical efficacy and safety.
We are committed to generic nanoformulation development based on our advanced design concept and reverse engineering research platform for RLD many years. Our solutions for generic nanformulation development are mainly include formulation and process studies, quality analysis and evaluation, in vitro PBE studies.

Based on our reverse engineering technology platform and uses appropriate characterization techniques to reverse analyze RLD. quality target product profile (QTPPs), and critical quality attributes (CQAs) are designed according to the QbD design concept to ensure that the types and amounts of excipients are consistent with the RLD, and the physical and chemical properties of the excipients that are critical to the performance of the nanoparticles are consistent. At the same time, we conduct in-depth research on key production processes such as emulsification, homogenization, filtration, and sterilization preparation methods to ensure that manufacturing equipment and process parameters are consistent with RLD.
Different nanoformulations have different structures and compositions, and their physical, chemical, and biological properties are also different. In the quality study of generic nanoformulations, we use appropriate methods to conduct a comprehensive analysis of COAs including but are not limited to, nanoparticle shape, surface characteristics such as surface charge and functionalization, drug loading and encapsulation efficiency, drug release, particle size and distribution, etc.
According to FDA regulatory guidance requirements, we use the mixed scale method to compare the in vitro population bioequivalence (PBE) of generic nanoformulations and reference products (RP). We are committed to the formulation development, quality analysis and in vitro PBE services for generic nanoformulations including lipid nanomedicines, polymer nanomedicines, nanocrystals, inorganic nanoparticles, protein nanoparticles, etc.
Technology: Characterization of generic citrate-coated gold nanoparticles (AuNPs)
Journal: Advanced Science
IF: 15.1
Published: 2021
Results:
The authors review the phenomenon of nanomaterial-induced endothelial leakage (NanoEL) induced by generic citrate-coated gold nanoparticles (AuNPs) of varying size and concentration and ranging from microscopic gap formation and actin reorganization to molecular signaling pathways and nanoscale interactions of AuNPs with VE-cadherin and its intra/extracellular cofactors. At the same time, the authors used a collaborative in silico approach to reveal the molecular and statistical mechanisms of cadherin response to disruption, specifically the response to the smallest size and highest concentration of AuNPs.
Compared with RLD, generic nanoformulations not only have the same quality and efficacy, but also have significant price advantages, providing convenience to patients. Therefore, the development of generic nanoformulations has attracted great attention from researchers. CD Formulation has consistently been a leader in the advancement of creating generic nanoformulation.
