Strategic Comparator Sourcing

Comparator sourcing is a bridge between two very different supply chains: Clinical and Commercial. Due to the growing cost of therapeutics, driven up by competitive pressures of biosimilar drugs, this bridge can be complex and heavily impacting the budget of your clinical studies. Access to industry expertise, market intelligence, sourcing networks and world leading services is important to optimize your trial.

A few general questions to start with:

  • Sourcing – should I leverage centralized or local sourcing?
  • How can l provide medicine to my patients faster?
  • How can we import comparator services to my study in specific countries (i.e. China…)?
  • How can we reduce waste and generate savings?

These and many more questions can be answered by our dedicated and global team of Comparator Sourcing Specialists that consult, assist and understand your sourcing needs. Along with our global footprint we guarantee product integrity and quality assurance by limiting supply chain steps.
