Lipocine Initiates a Dosing Flexibility Study for LPCN 1021, Its Oral Testosterone Replacement Product Candidate

SALT LAKE CITY, Jan. 05, 2017 (GLOBE NEWSWIRE) -- Lipocine Inc. (NASDAQ:LPCN), a specialty pharmaceutical company, today announced plans to initiate a dosing flexibility ("DF") study in addition to its previously announced dosing validation ("DV") study for LPCN 1021.  LPCN 1021 is an oral testosterone product candidate for testosterone replacement therapy ("TRT") in adult males for conditions associated with a deficiency of endogenous testosterone, also known as hypogonadism.  The DF study will assess LPCN 1021 in hypogonadal males on a fixed daily dose of 450 mg divided into three equal doses whereas the DV study is assessing the impact of LPCN 1021 in hypogonadal males on a fixed daily dose of 450 mg divided into two equal doses. Lipocine expects resubmission of the LPCN 1021 new drug application ("NDA") to the U.S. Food and Drug Administration ("FDA") to contain data from both the DV study and the DF study.

Lipocine expects the first patient of the DF study to be enrolled in the first quarter of 2017 with top-line results projected in the second quarter of 2017. The DF study is an open-label, fixed dose, single treatment arm study of LPCN 1021 and is expected to enroll 100 hypogonadal males.  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"). 

"We are pleased to initiate the DF study with LPCN 1021 as we continue to advance LPCN 1021 into a position for approval," said Dr. Mahesh Patel, Chairman, President and CEO of Lipocine. "We remain on track with our DV study and continue to expect top-line results from the DV study in the second quarter of 2017."

About LPCN 1021

LPCN 1021 is a novel 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 September 2016 for testosterone products.
