According to the Wall Street Journal, the layoffs impact employees at the company's facilities in Kenilworth, Rahway and North Wales, Pennsylvania. In addition to layoffs, some employees will be transferred to a new research facility expected to open in San Francisco in 2017.

The research unit has struggled in the last 10 years to develop a successful drug.

The company's headquarters are in Kenilworth.
