New drug-testing tech could drastically cut animal testing.Israeli human-on-a-chip platform has the unique ability to predict risk of toxicity in pharma and cosmetic product candidates without animal testing. After spending an average of $2.5 billion to develop a single new drug, sometimes pharma companies have to pull it from the market due to a bad outcome that was not detected in clinical studies.That’s what happened in 2000, when a promising Type 2 diabetes drug called troglitazone led to idiosyncratic (unexplained) liver damage in one of every 60,000 users. The troglitazone mystery wasn’t solved until March 2016, when a novel “liver-on-a-chip” platform developed by Hebrew University of Jerusalem Prof. Yaakov Nahmias revealed what no animal or human tests could: even low concentrations of this drug caused liver stress before any damage could be seen. “It was the first time an organ-on-chip device could predict information to help pharmaceutical companies define risk for idiosyncratic toxicity,”
