Dose translation from animal to human studies revisited.

Reagan‐Shaw, Shannon, Nihal, Minakshi, Ahmad, Nihal·2008·The FASEB Journal

Abstract

As new drugs are developed, it is essential to appropriately translate the drug dosage from one animal species to another. A misunderstanding appears to exist regarding the appropriate method for allomet‐ric dose translations, especially when starting new animal or clinical studies. The need for education regarding appropriate translation is evident from the media response regarding some recent studies where authors have shown that resveratrol, a compound found in grapes and red wine, improves the health and life span of mice. Immediately after the online publication of these papers, the scientific community and popular press voiced concerns regarding the relevance of the dose of resveratrol used by the authors. The animal dose should not be extrapolated to a human equivalent dose (HED) by a simple conversion based on body weight, as was reported. For the more appropriate conversion of drug doses from animal studies to human studies, we suggest using the body surface area (BSA) normalization method. BSA correlates well across several mammalian species with several parameters of biology, including oxygen utilization, caloric expenditure, basal metabolism, blood volume, circulating plasma proteins, and renal function. We advocate the use of BSA as a factor when converting a dose for translation from animals to humans, especially for phase I and phase II clinical trials.—Reagan‐Shaw S., Nihal, M., Ahmad N.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The dose of each SSRI administered in mice was within the range of what would be prescribed to human patients to treat depression, taking into account species differences in metabolism.

    “The dose of each SSRI administered in mice was within the range of what would be prescribed to human patients to treat depression (taking into account species differences in metabolism) (23).”
  • The dose of atorvastatin 40 mg/Kg in mice is equivalent to 3.24 mg/Kg in humans based on FDA mouse-to-human dose translation guidelines.

    “Worth noting is that the dose of each atorvastatin injection administered to mice in the study at hand, 40 mg/Kg, is equivalent to a dose of 3.24 mg/Kg in man based on United States Food and Drug Administration (FDA) mouse to human dose translation guidelines (Reagan-Shaw et al., 2008).”

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.
