Lipocine Announces Submission of SPA on LPCN 1107, an Oral Alternative for the Prevention of Preterm Birth

SALT LAKE CITY, June 26, 2017 (GLOBE NEWSWIRE) -- Lipocine Inc. (NASDAQ:LPCN), a specialty pharmaceutical company, today announced that it has submitted a Special Protocol Assessment ("SPA") request to the U.S. Food and Drug Administration ("FDA"), as part of the ongoing interaction with the FDA on the detailed design of the planned Phase 3 clinical development program for LPCN 1107 for prevention of recurrent preterm birth ("PTB") with history of singleton pregnancy. An SPA is an advanced declaration from the FDA that a planned trial's design, clinical endpoints, and statistical analyses could potentially result in data acceptable for FDA review towards approval for the proposed indication.

The proposed Phase 3 clinical trial has been designed as an adequate and well-controlled non-inferiority trial comparing LPCN 1107 with Makena®, the current standard of care for PTB.  Based on prior interactions with the FDA, Lipocine has proposed an efficacy endpoint focusing on the rate of delivery at less than 37 weeks gestation.  Success on this gestational age endpoint could lead to Subpart H approval by the FDA.  The proposed enrollment population is singleton pregnant women with a history of singleton spontaneous preterm birth.  The proposed trial has an adaptive design with an interim analysis.

"We have submitted an SPA request to the FDA with the goal of solidifying the development and regulatory pathway for LPCN 1107, and specifically, the details of our planned Phase 3 clinical trial," said Dr. Mahesh V. Patel, Chairman, President and CEO of Lipocine.  "Prevention of PTB is a significant unmet need with approximately 11.7% of all U.S. pregnancies resulting in this outcome (delivery less than 37 weeks). It is a leading cause of neonatal mortality and morbidity."
