WHITE PAPER

# The Hollow Fiber Model

**Discover the *In Vivo* Hollow Fiber Model — An Innovative Solution to Accelerate Drug Development.**

Are you struggling to validate *in vitro* findings before moving to *in vivo* studies? Traditional xenograft models can be costly, time-consuming, and resource-intensive. But what if you could streamline your entire testing process — from selecting lead compounds and identifying the most effective tumor models to simultaneously assessing PK/PD — in a cost-effective *in vivo* system?

Download our White Paper to learn the principles behind hollow fiber models and explore two compelling case studies showcasing their application for small molecules and antibodies.
