Impact of Discordance Among Regulations for Biopharmaceutics Classification System-Based Waivers of Clinical Bioequivalence Studies

Open access
Cook, Jack·2015·Dissolution Technologies

Abstract

Approximately 10 years ago, the FDA issued a guidance whereby dissolution could be used to establish bioequivalence for highly soluble and highly permeable immediate-release products.This pathway has advantages in lower costs for pharmaceutical companies and avoids unnecessary exposure of human subjects who would derive no medical benefit from participating in bioequivalence studies.Subsequently, other agencies have also adopted similar guidances.However, there are differences among agency guidances that significantly impact the number of compounds eligible for BCS-based biowaivers across all regulatory agencies.These include differences in BCS Classes for which biowaivers are considered, differences in the definition of highly permeable, and differences in the definition of highly soluble.The currently low rate of biowaiver submissions may in part be due to these differences.

  • In 2000, the US-FDA was the first regulatory agency to publish guidance for industry describing criteria for requesting a waiver of in vivo bioavailability and bioequivalence studies for highly soluble, highly permeable (BCS Class I) drugs.

    “In 2000, the US-FDA was the first regulatory agency to publish guidance for industry describing how to meet criteria for requesting a waiver of in vivo bioavailability and bioequivalence studies for highly soluble, highly permeable (BCS Class I) drugs.”

    From BCS Biowaivers: Similarities and Differences Among EMA, FDA, and WHO Requirements (2016) · cites this paper as [11]

    The Abstract describes FDA guidance for highly soluble, highly permeable immediate-release products, and References entry 2 dates the FDA’s BCS-based waiver guidance to 2000. However, the Introduction explicitly says the FDA published the first such regulatory guidance in 2005. The paper therefore supports the guidance’s purpose but gives conflicting dates for the claim’s key year. (LLM, conf=0.84)

  • The low rate of BCS-biowaiver submissions from 2000 to 2015 may have been due in part to these differences.

    “The low rate of BCS-biowaiver submissions from 2000 to 2015 may have been due in part to these differences (11); for example, from 2000 to 2015, the number of BCS biowaiver requests submitted to the US-FDA averaged approximately two per year (Mehta M.

    The Conclusions (page not available) say that differences among agency guidances may partly explain the currently low rate of biowaiver submissions. The paper does not establish that this explanation applies specifically to the stated 2000–2015 period. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The first regulatory guidances encouraging the use of the BCS for biowaivers of Class I immediate-release solid oral dosage forms were issued by the US-FDA in 2000 and by the EMA in 2001.

    “The first regulatory guidances encouraging the use of the BCS for biowaivers of Class I immediate-release (IR) solid oral dosage forms were issued by the US Food and Drug Administration (US-FDA) in 2000 (6,11) and by the European Medicines Agency (EMA) in 2001 (12).”

    From BCS Biowaivers: Similarities and Differences Among EMA, FDA, and WHO Requirements (2016) · cites this paper as [11]

    The References list the FDA’s BCS-based guidance for immediate-release solid oral dosage forms as issued in 2000. However, the Introduction says the FDA first published that guidance in 2005, and the copy does not give 2001 as the date of the EMA’s first guidance; its cited EMA guideline is dated 2010. The source therefore does not support the full chronology claimed. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
