Accelerating your path, we develop, execute and document phase appropriate methods necessary to produce high-quality, well-characterized material and the data to support successful BLA and marketing applications.

End-to-end support

Applying our expertise and experience, we develop data packages that support your regulatory approvals with all global agencies.

Our in-house analytical approach focuses on qualifying phase appropriate assays for a spectrum of testing including: safety, potency, purity, identity, and extended characterization that enable end-to-end support for:

  • Formulation
  • GMP manufacturing
  • Release and stability testing for GMP material

Stability

Offering a full spectrum of services, we support stability studies 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.
