San Diego’s Millennium Laboratories Inc. has acquired RxAnte Inc. for an undisclosed sum, the companies announced.

RxAnte, a McLean, Va.-based health care predictive analytics company, was founded in 2011 and has raised about $4.5 million in Series A funding from San Francisco-based Aberdare and San Diego’s West Health.

The acquisition will help Millennium personalize prescription drug therapy plans, deliver targeted patient support programs and monitor patient outcomes, Millennium said.

Millennium, a fast-growing company that employs about 1,300 in its Poway headquarters, offers medication monitoring using urine testing and pharmacogenetic testing to health providers that treat pain, substance abuse disorders, psychiatric disorders and other chronic diseases.
