On 3/13/13, FDA notified the sponsor that the BCS Committee at CDER approved their request for a BCS Class-1 classification for cyclophosphamide capsules.BCS CLASS I High solubility High permeabilityThe Biopharmaceutics Classification System (BCS) is a scientific scheme that. During this time, you may not be able to schedule, reschedule or cancel test.Note that the firm’s requests for a BCS-Class 1 assignation for cyclophosphamide and for a BCS-based biowaiver were reviewed and approved under their IND 112,446 submission.
A drug is considered to have high solubility if drug substance at the highest dose strength for an immediate release formulation can be dissolved in 90%) or exhibits rapid movement through intestinal epithelia cells in vitro. BCS class II compounds (low solubility, high permeability)Table 3.6. BCS class I compounds (high solubility, high permeability)Adapted from Wu and Benet (2005) Table 3.5. Those compounds are well absorbed and their absorption rate is usually higher than excretion.The BCS classification system is used to categorize drugs and serves to help anticipate whether drugs will have bioavailability/ bioequivalence problems.
Thus, it may be possible to waive clinical DDI studies as well.“If in vitro experiments demonstrate that an NME is a P-gp substrate, additional drug-specific factors may be considered before determining whether an in vivo drug interaction study is warranted. For such compounds, the rate and extent of drug absorption is unlikely to be affected by drug dissolution and/or GI residence time, and in vivo bioequivalence studies (for new formulations, etc.) may be waived based on in vitro permeability and solubility data.BCS Divides Compounds into Four Categories:Class I – High Solubility, High PermeabilityClass II – Low Solubility, High PermeabilityClass III – High Solubility, Low PermeabilityClass IV – Low Solubility, Low PermeabilityFurthermore, for Class I compounds, it is unlikely that absorption will be limited by efflux transporters. According to the 2000 FDA BCS Guidance, compounds that are classified as Class I (highly soluble, highly permeable) are eligible for BCS biowaivers. Preclinical Toxicology Testing ServicesBiopharmaceutics 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. Physicochemical Properties/Dose Selection
This, combined with our 10-day turnaround for pre-qualification and our cost effective designs, saves you time and money. 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. Eight of the ten largest generic drug companies have conducted in vitro BCS biowaiver studies with Absorption Systems. Zhang et al., “Predicting Drug-Drug Interactions: An FDA Perspective” (2009) The AAPS JournalAbsorption Systems, World Leader in Biopharmaceutics Classification SystemAbsorption Systems has performed dozens of BCS classification studies over the past ten years, many of which have resulted in successful BCS biowaiver submissions.
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.
