Lipocine Announces Successful Completion of Food Effect Study for LPCN 1021, an Oral Testosterone Product Candidate

  • Consistent and predictable therapeutic levels of testosterone when administered with a meal
  • No significant sensitivity to meal fat content

SALT LAKE CITY, June 15, 2015 (GLOBE NEWSWIRE) -- Lipocine Inc. (Nasdaq:LPCN), a specialty pharmaceutical company, today announced the successful completion of its labeling "food effect study" for LPCN 1021, its Oral Testosterone product for hypogonadal men with low testosterone. Lipocine conducted the study per the U.S. Food and Drug Administration ("FDA") requirement for submitting the New Drug Application ("NDA") for LPCN 1021.

"Successful completion of the food effect study is another significant milestone towards both the filing of our NDA for LPCN 1021and potentially bringing this important new convenient therapeutic option to patients," said Dr. Mahesh Patel, Chairman, President and CEO of Lipocine Inc. "Importantly, we remain on track to announce one-year safety data from the pivotal Phase 3 study by the end of June, as well as file the NDA in the second half of the year."

The labeling "food effect" study was an open-label, randomized, four-period, four-treatment, crossover, single-dose study evaluating bioavailability and pharmacokinetics of LPCN 1021 as a function of meal and meal fat content in hypogonadal males. Subjects received a single LPCN 1021 dose of 225 mg testosterone undecanoate (the starting dose in the completed Phase 3 clinical study) under fasted conditions and under the following fed conditions (approximately 30 minutes following an 800 to 1000 calorie meal): 15% of calories from fat ("low fat meal"), 30% calories from fat ("standard fat meal"), and 50% calories from fat ("high fat meal"). The study enrolled 14 hypogonadal males with 13 subjects completing the study.

Topline results from the labeling "food effect" study indicate that bioavailability of testosterone from LPCN 1021 is not affected by changes in meal fat content. The results demonstrate comparable testosterone levels between the standard fat meal (similar to the meal instruction provided in the Phase 3 clinical study) and both the low and high fat meals. Testosterone levels were also comparable between the low fat and high fat meals. Based on the comparative analysis of testosterone exposure in this study, LPCN 1021 bioavailability is not sensitive to low, standard, or high fat meal content. Preliminary data for the pharmacokinetic parameters of maximum observed serum concentration ("Cmax") and area under the curve ("AUC") for testosterone following administration of LPCN 1021 under fed conditions with meals of varying fat content are presented in Table 1.

Administration of LPCN 1021 under fasted conditions resulted in a significant reduction in bioavailability as presented in Table 2.

About LPCN 1021

The current testosterone market is dominated by topical products that are associated with poor patient compliance and FDA "black box" warnings related to inadvertent transfer of testosterone. LPCN 1021 is a twice-a-day, oral product candidate with three simple oral dosing options that we expect will overcome the major shortcomings of existing products.
