Tucson, Ariz.-based biotech firm HTG Molecular Diagnostics has filed for chapter 11 bankruptcy protection, with plans to continue operations as it works out a plan to pay its debts, Tucson.com reported. The company, which developed a proprietary platform to rapidly develop molecular drug compounds, plans to exit that business to focus on its own development of new drugs to treat cancer and other diseases, according to bankruptcy filings. In a bankruptcy petition filed June 5 in Delaware, HTG’s corporate domicile, the company listed assets totaling about $6.7 million and debts of about $9 million.
