Alere Inc., a Waltham company that last year sold about $3 billion worth of medical diagnostic products, said Tuesday that chief operating officer Namal Nawana has been appointed interim chief executive and president following the resignation of Ron Zwanziger as CEO, president, and a company director, effective immediately.

Jerry McAleer, senior vice president of research and development and a company director, and Dave Scott, chief scientific officer, have also resigned, Alere said in a press release.

The moves are part of the company's "ongoing review of its strategy and operations," the release said. The company's board will now start a search for a permanent chief executive.


In May, Alere announced that it had separated the roles of chairman of the board and chief executive. Previously, Zwanziger held the titles of chairman, president, and chief executive. At that time, Alere said its board had unanimously elected Gregg J. Powers as chairman. It added then that Zwanziger would continue as president, chief executive, and a member of the company's board.

Tuesday's press release included a statement from Powers, who said: ''On behalf of the entire Alere board, I would like to thank Ron, Jerry, and Dave for their years of leadership. 'Since founding the company in 2001, Ron, Jerry, and Dave have led Alere's growth into a leading global health care company providing point-of-care diagnostics, health information systems, and chronic care management programs. We believe that with Alere's talented management team in place, now is the right time for the company to transition to new leadership.''

Nawana has served as Alere's chief operating officer since December 2012. Before joining the company, Nawana spent 15 years at Johnson & Johnson in various leadership roles.
