Using its proprietary oral Lip'ral™ technology, Lipocine has developed an investigational oral testosterone product. Solvay Pharmaceuticals plans to initiate a development program to further study the investigational product as an oral treatment for male hypogonadism also known as low testosterone (low T).

"This agreement further demonstrates Solvay Pharmaceuticals' commitment to men suffering from low testosterone," said Dr. Stephen Hill, President, Solvay Pharmaceuticals, Inc. "As the market leader in the field, we will apply our expertise in the treatment of low testosterone to the development of an oral testosterone replacement therapy. This compound has the potential to be the next major innovation in the management of low testosterone."

"We are quite pleased to partner with Solvay Pharmaceuticals, a leader in testosterone replacement therapy, to bring this innovative treatment option to patients." said Dr. Mahesh Patel, President and CEO, Lipocine Inc.

Under the terms of the agreement announced today, Solvay Pharmaceuticals will make an upfront payment, make future milestone payments and pay royalties based upon product sales to Lipocine. Solvay Pharmaceuticals will also fund Lipocine development expenses associated with this program.

It is estimated that hypogonadism, also known as low testosterone, affects more than 13 million men in the United States age 45 and older. Because signs and symptoms of low testosterone are subtle and often overlap with other common medical conditions, low testosterone is frequently undiagnosed. Signs and symptoms of low testosterone may include low sex drive, erectile dysfunction, fatigue, depressed mood, reduced muscle mass and strength, increased fat body mass and decreased bone mineral density.
