Boston’s PureTech raises $50 million for healthcare research

PureTech Ventures, LLC, a Boston-based funder of healthcare research, has raised an additional $50 million from investors.

The company, which also goes by the name PureTech Health, has large shares in a dozen therapeutic and healthcare technology companies and says it helps them grow and commercialize their research. The company said it reviews about 800 proposals a year. Combined with the $57 million it raised in Oct. 2014, PureTech has raised $107 million in the last four months.

‘‘It’s exciting to see that a number of these truly innovative approaches are generating proof of concept in validating studies and the recent institutional financing is a further recognition of this potential,” said Dr. Robert Langer, a senior partner at PureTech and professor at MIT.
