Anthony Ratcliffe, CEO of Synthasome Inc., of Del Mar, Calif., said on a recent FDA webinar that companies might want to consider the lowly goat as the animal model of choice in preclinical studies of cartilage products because “the cost, ease of management, and the social aspects were all manageable” with goats.

The FDA has issued new risk classification orders for two series of products, including in vitro diagnostics for hepatitis C, two of which the agency down-regulated from class III to class II. However, blood lancets for multiple uses on more than one patient has been elevated from class I to class III, a change that has no impact on any products currently available on the U.S. market.
