Pfizer plans to vacate 46,000 square feet of office space in Cary that it acquired as part of its purchase of King Pharmaceuticals earlier this year.

The move will affect about 60 employees, many of whom will be relocated to Pfizer’s offices in Durham or its vaccine facility in Sanford.

“We’re going to be consolidating as many of these functions as we can to those two sites,” said Rick Chambers, a company spokesman.

King occupies two floors of an office building on Highwoods Properties CentreGreen campus. The company’s lease doesn’t expire until late 2014.

Pfizer plans to close the office by the end of the year and sublease the space.
Chambers said there’s a possibility that some employees in Cary may be let go.

“It’s too soon to know how many positions may be eliminated,” he said.

Research in Motion, the Canadian company that makes the BlackBerry devices, has expanded its presence in the Triangle.

The company said in a regulatory filing this week that it has added more office space in Highwoods Properties CentreGreen campus in Cary and now occupies a total of 78,000 square feet.

RIM has been tight-lipped about its operations in the Triangle ever since initially announcing last year that it planned to open an office in the region.

RIM is part of a growing cluster of mobile technology companies that have recently opened offices in the Triangle.
