Cytochroma, Inc., a company managed by former employees of Bone Care International, has announced the settling of a lawsuit filed in August 2006 by Genzyme Corp., the company that acquired Bone Care in 2005.

The lawsuit, in which Genzyme claimed that the former Bone Care employees had begun to develop the company's trade secrets into new products, was being adjudicated in the United States District Court, Western District of Wisconsin.

Genzyme filed the suit in August of 2006 against Cytochroma Inc., Proventiv Therapeutics, LLC, and the three former Bone Care International employees.

The complaint alleged the misappropriation of Vitamin D-related trade secrets, and has been formally dismissed. The terms of the settlement were not disclosed.

The three former Bone Care employees - Charles Bishop, Keith Crawford, and Eric Messner - formed Proventiv Therapeutics, which was acquired by Cytochroma in 2006.

Cytochroma is a pharmaceutical company that is developing products to treat and prevent diseases and disorders related to vitamin D hormone deficiency. The company is deciding whether to open an office in Madison.
