By utilizing our deep knowledge of complex chemistry and bioconjugation we rapidly develop and streamline your program development and commercial timelines.

An experienced team of process, analytical and manufacturing experts carry out manufacturing in an upgraded facility with well-established controls (engineering, administrative, and PPE controls) for handling cytotoxic materials.

Our Process Development Capabilities

Our process development approach is defined and designed to ensure scale up directly from bench scale to final manufacturing.

Our experience goes beyond ADCs, including bioconjugates, oligonucleotides, nanoparticles, and vaccines.

Development capabilities include:

  • Process development for small molecules, including high potency chemistry
  • Multiple linker chemistries
  • Design of Antibody Drug Conjugates
  • Bench scale process characterization and validation
  • Design of statistical experiments to optimize processes
  • Transfer verification optimization of your process

Our Process Design Capabilities

Material generated is used to develop your early-stage material for analytical and formulation development.

Process Development works with Analytical Method Development (AMD) to determine its quality attributes. We design your processes to optimize yields and remove impurities with minimal steps and optimal recovery.

We have years of experience in characterization and supporting the selection of the best candidates for progressing to clinical studies.

Early candidates can be produced from different antibodies, types of linkers and payloads to screen for the most potent solution for your target.

Our process design capabilities include:

  • Conjugation reaction optimization
  • Chromatographic purification steps including ion-exchange, hydrophobic interaction, metal affinity, etc.
  • Column chromatography from 1ml through 20L of bed volume
  • TFF step optimization
  • Filter sizing studies
  • Lyophilization cycle development
  • Stability on process intermediates and process hold steps
  • Determination of Critical Quality Attributes (CQAs) and Critical Process Parameter (CPPs) validation


Offering a full spectrum of services, we support stability for drug substance, drug product and in-use testing per ICH guidelines.

Stability indicating assays are identified early on via forced degradation studies performed during process development.

Following completion of stability time point testing, a final stability summary report is provided to support your clinical studies and market authorization applications.
