The story
In the first quarter of 2006, DUSA acquired Sirius Laboratories in a transaction valued at approximately $30 million. Sirius was a privately held specialty pharmaceutical company founded by dermatologist Joel E. Bernstein in 2000. It developed treatments for conditions including acne vulgaris and rosacea.
In June 2007, Robert F. Doman was elected chief executive officer. Shulman remained chairman of the board and assumed the position of chief strategic officer. In April 2008, DUSA announced that Shulman's role was expected to change because of a serious illness. His employment agreement was terminated in December 2008 and replaced by a part-time consulting arrangement, with company filings citing his health.
In 2012, Caraco Pharmaceutical Laboratories, a subsidiary of Sun Pharmaceutical, acquired DUSA.
