You know it’s a quiet week for healthcare M&A when only one pharmaceutical deal is announced. Last week, Tanner Pharmaceuticals, a portfolio company of Bourne Partners, paid an undisclosed sum for specialty pharma company BurnsAdler Pharmaceuticals. Both companies are based in Charlotte, North Carolina. The two have merged to form Tanner Pharma Group, which includes Tanner Clinical Trial Sourcing, Tanner Global Access Programmes, and Tanner Licensing, Acquisition and Commercialisation. Although the company is headquartered in the United States, it has offices in London, Sao Paulo and Mexico City.
