WuXi Biologics' WuXiHighTM High-throughput High Concentration Formulation Development Logo

High throughput formulation development platform for high concentration biologics drug products 

 

The WuXiHighTM platform provides customized biologics formulation development strategies for high concentration drug products (up to 230 mg/mL).  The platform can be applied to a variety of biological modalities, such as monoclonal, bispecific and multispecific antibodies, fusion proteins, and other recombinant proteins. Its distinctive viscosity reducers and synergistic excipient combinations enhance formulation stability and reduce viscosity. As an industry-leading high concentration drug product (DP) development platform, WuXiHigh integrates advanced computer simulation technologies like homologous modeling, molecular dynamics simulation, and machine learning. Through this integration, formulation development is achieved more efficiently and with less risk by leveraging computational simulation results, high-throughput experimental screening, and experimental verification.

 

To enable efficient protein characterization, the platform is equipped with high-throughput equipment including UNcle, HT-DLS, Rheosense, as well as novel technologies such as LF-NMR. WuXiHigh also offers tailored process development and technology transfer strategies for drug substance (DS) and drug product (DP) across a wide range of viscosities (up to 21.5 cP). Additionally, the platform facilitates the development, production, assembly and fill of prefilled syringes and autoinjectors. With a wealth of experience from over 70+ projects in high concentration formulation development and manufacturing, the platform has acquired significant expertise and a knowledge database, allowing us to provide comprehensive end-to-end formulation and drug product development services to our global clients.

 

Regardless of your development phase, our scientists design the ideal formulation that can be adapted for the container closure system (CCS) of your choosing. Ready-to-sterilize (RTS) and ready-to-use (RTU) vials in multiple sizes are available for liquid, frozen, and lyophilized dosage forms. For clients looking for specialized drug delivery systems, prefilled syringes (with or without NSD) and autoinjectors are also available.

 

 

Container Closure Systems Features:

 

  • Vials in 2R, 6R, 8R, 10R, 14R, 20R, and 50R sizes with RTS and RTU configurations
  • Prefilled syringes (PFS) in 1 mL long, 1 mL standard, 2.25 mL, 3 mL syringe with staked needle or luer lock design
  • PFS with passive needle safety device (NSD) options
  • Autoinjector products optimized for improved user experience
  • Pilot, clinical phase and large-scale commercial GMP production for all CCS types

 

To expedite your path to clinical or commercial drug product manufacturing, our team of DP development experts support the drug product fill process development, scale-up and characterization using well established lab-scale models and full state-of-the-art analytical support.

 

 

Leveraging our advanced and automated fill line technologies, we offer a variety of process development and technology transfer services for process development for RABS (Restricted Access Barrier Systems), isolator-based filling lines, and fully-automated Vanrx systems including:

 

  • Pilot scale (non-GMP) fill finish and lyophilization services for preclinical toxicology studies, non-GMP stability studies and scale-down process development
  • End-to-end drug product fill process development from drug substance thawing through mixing, filtration, filling, stoppering and capping to final visual inspection.
  • Lyophilization cycle development and optimization
  • Container and closure selection and integrity testing

 

With the increasing number of patients with chronic diseases and growing trend in at-home healthcare, improved drug delivery solutions are becoming more vital to patient health and safety. Combination products such as prefilled syringes (PFS), PFS with needle safety devices (NSD) and autoinjectors offer greater convenience, operability and compliance to foster better patient outcomes.
