• Top-line data from the studies expected in June 2017

SALT LAKE CITY, UT, USA I April 24, 2017 I Lipocine Inc. (NASDAQ:LPCN), a specialty pharmaceutical company, today announced the completion of enrollment for both its dosing validation (“DV”) study and its dosing flexibility (“DF”) study for LPCN 1021.  LPCN 1021 is an oral testosterone product candidate for testosterone replacement therapy in adult males for conditions associated with a deficiency of endogenous testosterone, also known as hypogonadism.

“We are pleased to complete enrollment for the DV and DF studies which do not require any dose titration; thereby addressing the cited deficiency in the U.S. Food and Drug Administration’s (“FDA”) Complete Response Letter,” said Dr. Mahesh Patel, Chairman, President and CEO of Lipocine. “We look forward to announcing the top-line results from these studies in June 2017, an important milestone toward the resubmission of LPCN 1021.”

The DV study will assess LPCN 1021 in hypogonadal males on a fixed daily dose of 450 mg divided into two equal doses. The DV study is an open-label, fixed dose, no titration single treatment arm study of LPCN 1021.  Efficacy will be assessed via responder analysis at the end of the dosing period which is 24 days.  The pre-specified primary endpoint is the percentage of subjects with an average 24-hour serum testosterone concentration (“Cavg”) within the normal range, with secondary endpoints based on maximum serum testosterone concentrations (“Cmax”).

The DF study will assess LPCN 1021 in hypogonadal males on a fixed daily dose of 450 mg divided into three equal doses. The DF study is an open-label, fixed dose, no titration, single treatment arm study of LPCN 1021.  Efficacy will be assessed via responder analysis at the end of the dosing period which is 24 days.  The pre-specified primary endpoint is Cavg within the normal range, with secondary endpoints based on Cmax.

About LPCN 1021

LPCN 1021 is an oral testosterone replacement therapy product candidate containing Testosterone Undecanoate that is designed to help restore normal testosterone levels in hypogonadal men. Lipocine expects LPCN 1021 will help fulfill an unmet need in the treatment of hypogonadism. The current testosterone market primarily uses short-acting injectable products as well as topical products that carry an FDA “black box” warning related to inadvertent transfer of testosterone to others. Per the IMS Health database, an average of 540,000 prescriptions a month have been dispensed from January 2016 through December 2016 for testosterone products.
