Intuity Medical said today that it added another $15 million to the $40 million Series C round it reported late last year, bringing the round’s total to $55 million.

Sunnyvale, Calif.-based Intuity said KCK Group joined round leaders PTV Healthcare Capital and affiliates of Luther King Capital Management as new investors; existing backers Accuitive Medical Ventures, Investor Growth Capital, U.S. Venture Partners, Venrock and Versant Ventures also participated.

The Intuity is developing the Pogo 1-step blood glucose meter, which won 510(k) clearance from the FDA in April 2016. It’s designed to combine the lancing, blood collection and analysis functions involved in measuring blood glucose into a single step.

“The additional funding will help further our commercialization efforts in bringing POGO Automatic to the U.S. market for patients who have been looking for a convenient way to test their glucose,” president & CEO Emory Anderson said in prepared remarks.

Intuity, a spin-off of research group Sarnoff Corp., has raised some $109.1 million since February 2010, including $5.5 million drummed up back in early 2014 and a $12 million round in 2012, according to regulatory filings:
