Eloxx Pharmaceuticals, a subsidiary of La Jolla’s Sevion Therapeutics Inc., has raised $6 million.

The investment was led by OPKO Health Inc., OPKO Chairman and CEO Dr. Phil Frost, and Israel-based venture capital firm Pontifax.

The new money brings the company’s total Series C round to $30 million, according to Eloxx.

The cash was part of an acquisition transaction between Sevion and Eloxx, the companies said in a joint statement. On June 2, the companies announced that Sevion would acquire Eloxx.
