Eisai Inc., an Andover pharmaceutical manufacturer that employs 240 people in town, is laying off 72 employees from its two, local facilities and closing down one of its research divisions.
The company, which makes health care products including cancer and Alzheimer’s treatments, has two facilities, including a six-year-old, $65 million, state-of-the-art research lab on Corporate Drive.
The layoff of roughly 30 percent of Eisai’s local workforce was announced in a letter late last month to the Board of Selectmen from the company’s human resources department in Woodcliff Lake, N.J.
“This is part of a reorganization plan that will include the closing of its pilot plant, the reduction of a significant portion of the Pharmaceutical Science and Technology Core Function Unit in Andover, and workforce reductions in other Andover departments,” the letter said. “These actions are expected to be permanent.”
By law, companies intending to make large-scale layoffs are required to inform local authorities in advance.
The layoffs are expected to take effect Dec. 31, 2013.
A spokeswoman for Eisai, Suzanne Grogan, said Monday that it’s not just Andover that’s being affected. She said 7 percent of Eisai’s global research and development organization is also affected.
“We are always looking at ways of strengthening our capabilities,” she said. “This is part of our periodic evaluation of our resources. We have to make sure we have our resources allocated to our key projects.”
She said Andover would continue to be a hub for discovery research.
The company employs about 10,500 people worldwide. In the U.S., there are about 1,500 Eisai employees and another 300 working for Eisai subsidiaries.
She said layoffs are also being made at the company’s New Jersey headquarters and at one of the subsidiaries in Pennsylvania.
The last layoff by the company was in spring 2011, when 20 percent of the company was cut across the board, she said.
