Lipocine Submits NDA to FDA for Its Oral Testosterone Replacement Product Candidate, LPCN 1021

SALT LAKE CITY, UT, USA I August 31, 2015 I Lipocine Inc. (LPCN), a specialty pharmaceutical company, today announced that it has submitted a 505(b)(2) New Drug Application ("NDA") to the U.S. Food and Drug Administration ("FDA") for LPCN 1021, an oral testosterone product candidate for testosterone replacement therapy ("TRT") in adult males for conditions associated with a deficiency or absence of endogenous testosterone ("hypogonadism").

"Filing of the NDA for LPCN 1021 is a significant achievement for Lipocine and a major milestone toward bringing this potential testosterone replacement therapy option to patients. LPCN 1021 has the potential both to improve the ease of use compared to the available formulations, including topical gels and injections, and to overcome inadvertent testosterone transference risk to children and partners," said Dr. Mahesh Patel, Chairman, President and CEO of Lipocine Inc. "We look forward to working closely with the FDA during the review process."

The NDA filing is supported by results from Lipocine's Study of Oral Androgen Replacement ("SOAR") pivotal Phase 3 clinical study ( evaluating efficacy and safety of LPCN 1021 in hypogonadal men with low testosterone. The study met its primary efficacy endpoint by successfully restoring testosterone levels to the normal range in 88% of the subjects. In addition, 85% of the subjects reached their final dose with no more than one dose titration. LPCN 1021 treatment was well tolerated with no hepatic, cardiac, gastrointestinal or drug related serious adverse events.

About LPCN 1021

LPCN 1021 is a twice-a-day, oral testosterone replacement therapy product candidate with three simple oral dosing options that Lipocine expects will overcome the major shortcomings of existing products. The current testosterone market is dominated by topical products that carry FDA "black box" warnings related to inadvertent transfer of testosterone and by injectable products. The IMS Health database shows that an average of half a million prescriptions a month have been dispensed so far in 2015 for TRT.
