March 28, 2018Robust non-animal models and assays for pulmonary toxicology are required to make competent product development and risk assessments for new materials requiring toxicity testing. Three in vitro assays (goblet cell hyperplasia [GCH], ciliary beat frequency [CBF], and MUC5AC quantitation) were evaluated for performance and reproducibility. To assess these assays, 6 laboratories contributed data using a common protocol utilizing IL-13 as an inducer of adverse mucociliary-relevant tissue changes. MatTek EpiAirway™ and Epithelix MucilAir™ 3D tissue models were used to evaluate endpoints...

March 28, 2018While data are still being collected and analyzed, there were at least 1,300 accidental electronic liquid (e-liquid) exposures reported as of 2013. Deaths have occurred as a result of ingestion of e-liquid with the effects being attributed primarily to nicotine.
The Food and Drug Administration (FDA) sought to regulate e-liquid through the Tobacco Control Act passed in 2009. In 2014, the FDA issued its “Deeming” proposals for public comments, which covered e-liquid manufacturing; the Final Rule giving the FDA authority to...

August 21, 2017Study in Response to Consumer Demands for Humane Testing
Washington, D.C. — August 21, 2017 — A first-of-its kind collaborative project is underway to find a non-animal test method to replace the rabbit vaginal irritation test for personal lubricants. The U.S. Food and Drug Administration (FDA) gave the project a green light as part of the agency’s program aimed at modernizing the tests used to develop and evaluate medical devices.
The work of the lubricant industry, the Institute for In Vitro Sciences...
Vaginal Irritation | Cosmetic & Personal Care
August 24, 2016The irritation potential of pharmaceutical, cosmetic and personal care products, medical devices and related consumables (such as lubricants)* that are formulated for application onto human cervical or vaginal tissues can be evaluated using reconstructed organotypic models representative of human ecto-cervical and vaginal tissue. These models overcome some of the disadvantages of monolayer culture by the presence of a barrier layer that permits the direct apical application of active ingredients and final formulations, including mixture, formulations and ingredients that are not...
Vaginal Irritation
August 24, 2016The safety assessment of raw ingredients or finished products intended for human oral use or that can accidentally come in contact with humans’ oral tissues can be performed using in vitro testing platforms based on reconstructed tissue models. The oral irritation potential of oral care, pharmaceutical or tobacco products can be investigated using the tissue viability (%) as main endpoint in the evaluation of cytotoxicity.
The potential oral/buccal irritation of raw ingredients or finished products can be assessed using commercially available...
