The importance of minipigs in dermal safety assessment: an overview.

The use of miniature swine as a non-rodent species in safety assessment has continued to expand for over a decade and their use has become routine, particularly in pharmacology as a model for human integumentary diseases. Translational preclinical swine study data are now favorably compared and contrasted to human data, and miniature swine models provide important information in dermal safety assessment and skin pharmacology. For example, the miniature swine model has been well-accepted for cutaneous absorption and toxicity studies due to swine integument being morphologically and functionally similar to human skin. Subsequently, this model is important to dermal drug development programs, and it is the animal model of choice for assessment of dermal absorption, local tolerance and systemic toxicity following dermal exposures. In conclusion, the miniature swine model has an important role to play in the safety assessment of pharmaceutical products and in multiple aspects of human dermal drug development.

The Miniature Swine as a Model in Experimental and Translational Medicine.

The use of the miniature swine as a nonrodent species in research has continued to expand for over a decade, and they are becoming routinely used both in experimental pharmacology and as a therapeutic model for human diseases. Miniature swine models are regularly used for studies designed to assess efficacy and safety of new therapeutic compounds given through different routes of exposure and are used as an alternative model to rodents, canines, or nonhuman primates. Translational preclinical swine study data presented here support the current understanding that miniature swine are the animal model of choice for the assessment of drugs targeting endocrine, dermal, and ocular disorders. Because research investigators need to be familiar with some of the important features of the models developed in the miniature swine in order to place clinical and experimental findings in their proper perspective, relevant references and data from these models will be presented, compared, and partially illustrated.

Miniature Swine Breeds in Toxicology and Drug Safety Assessments: What to Expect during Clinical and Pathology Evaluations.

The use of miniature swine as a nonrodent species in safety assessment has continued to expand for over a decade, and they are becoming routinely used in toxicology and in pharmacology as well as a model for human diseases. Miniature swine models are regularly used for regulatory toxicity studies designed to assess safety of new therapeutic compounds given through different routes of exposure and are used as an alternative model to the canine or the nonhuman primate. Translational preclinical swine study data presented support the current finding that miniature swine are the animal model of choice for assessment of drug absorption, tolerance, and systemic toxicity following systemic exposures. Because research investigators need to be familiar with important anatomic and histopathologic features of the miniature swine in order to place toxicopathologic findings in their proper perspective, clinical and anatomic pathology data from a large number of Sinclair, Hanford, Yucatan, and Göttingen breeds from control groups from a wide variety of studies performed between 2004 and 2014 will be presented, compared, and partially illustrated.
