Biopharmaceutics Classification

We Are the World Leader in Biopharmaceutics Classification System

BCS BiowaviersAbsorption Systems has performed dozens of BCS classification studies over the past ten years, many of which have resulted in successful BCS biowaiver submissions. Eight of the ten largest generic drug companies have conducted in vitro BCS biowaiver studies with Absorption Systems.  It was our permeability data that supported some of the very first in vitro BCS biowaivers.

Our extensive experience continues to facilitate innovative solutions and enable in vitro classification for a broader range of drugs. This, combined with our 10-day turnaround for pre-qualification and our cost effective designs, saves you time and money. Just a few reasons why Absorption Systems averages more than 30 BCS studies each year.

Avoid expensive and time consuming clinical bioequivalence studies with in vitro solubility, permeability, and dissolution data. It is a critical optimizer in time and money for drug developers.

Our validated 3-step study design allows for early identification of BCS biowaiver candidates and optimization of protocol elements. These steps include: 

1.

Pre-qualification and determination of the eligibility of test compound for BCS biowaiver. Your go/no-go decision point.

2.

Protocol optimization and conduct of FDA-required experiments to establish protocol for pivotal studies.

3.

GLP BCS classification of permeability and/or solubility

BCS Classification

BCS Biowaivers Background Information
Biopharmaceutics Classification System (BCS) is a regulatory mechanism through which drug developers and generic companies can obtain a waiver of clinical bioequivalence studies, also called a biowaiver.

BCS Classification Studies Per Year

A Decade of BCS History
Absorption Systems has performed dozens of BCS studies over the past ten years, resulting in some of the very first BCS biowaivers granted by the FDA.


Translating Cellular Science into Human Outcomes
The FDA explicitly recommends the BCS approach for many drugs and welcomes data for any qualified candidate. Find out which clinical studies you could potentially waive by using Absorption Systems’ dually validated Caco-2 test system.


Redefining the Threshold for Permeability Classification
The permeability threshold defined by Absorption Systems novel High Permeability Internal Standard is the lowest available, about 7-fold less than metoprolol.
