Drugmaker Eli Lilly and Co. says it'll build a $3.5 billion manufacturing facility in Pennsylvania, as the company expands domestic production and capitalizes on surging sales of obesity and diabetes treatments. The company said Friday that the new plant will make injectable drugs and devices. Eli Lilly, maker of weight-loss treatment Zepbound and diabetes drug Mounjaro, has also announced new plants in Texas, Virginia and Alabama, and another facility is under construction in Indiana.
