INDIANAPOLIS — Eli Lilly and Co. has settled another 900 personal-injury claims against its antipsychotic drug Zyprexa, including five set to go to court next month, thus avoiding what would have been the first trial in the U.S. The Indianapolis drug maker confirmed the settlement Wednesday but declined to reveal the amount. With the latest agreements, Lilly has settled more than 25,000 claims, leaving about 1,100 unsettled. Many of the plaintiffs have claimed Lilly underplayed the drug’s side effects, including weight gain and elevated blood sugar. Lilly has set aside $1.2 billion to pay claims.
