SAN DIEGO, Jan. 09, 2017 (GLOBE NEWSWIRE) -- Retrophin, Inc. (NASDAQ:RTRX) today announced that, based on preliminary and unaudited financial data, the Company expects net product sales for the fourth quarter of 2016 to be approximately $37 million. For the fiscal year 2016, the Company expects total net product sales of approximately $134 million.  

"2017 is an important year for Retrophin as we continue to advance our two clinical programs towards NDA filing," said Stephen Aselage, chief executive officer of Retrophin. "We look forward to our meeting with the FDA later this month regarding the regulatory pathway for sparsentan in FSGS, as well as dosing the first patient in our Phase 3 trial evaluating RE-024 for PKAN in the coming months. In addition, we closed the year with strong financial performance and anticipate revenue growth will continue in 2017 which will provide further financial support to develop our maturing pipeline."

In early March, the Company expects to announce final financial results from the fourth quarter and full-year 2016, as well as a detailed corporate update, in a press release and conference call.
