Lipocine Inc. (NASDAQ: LPCN), a clinical-stage biopharmaceutical company focused on metabolic and endocrine disorders, today announced it has entered into an exclusive licensing agreement with Antares Pharma, Inc. to commercialize TLANDO in the United States.  TLANDO is an oral testosterone product for testosterone replacement therapy ("TRT") in adult males indicated for conditions associated with a deficiency or absence of endogenous testosterone: primary hypogonadism (congenital or acquired) and hypogonadotropic hypogonadism (congenital or acquired).

As previously announced, the U.S. Food and Drug Administration ("FDA") granted tentative approval to TLANDO.  Upon the expiration of the exclusivity period granted to Clarus Therapeutics, Inc., with respect to its drug, JATENZO^®, under the Hatch-Waxman Act, which expires on March 27, 2022, TLANDO will be eligible for final approval. The FDA has affirmed the NDA resubmission for final approval will be a Class 1 resubmission which includes a two-month FDA review goal period.

Under the terms of the agreement, Lipocine will receive an immediate upfront cash payment of $11.0 million and, subject to certain conditions, an additional $5.0 million licensing payment in January 2025 and another $5.0 million licensing payment in January 2026.  Lipocine will also be entitled to receive sales-based commercial milestone payments totaling up to $160.0 million based on TLANDO net sales and, if Antares Pharma exercises its option, TLANDO XR sales, in addition to tiered royalty payments at rates ranging from the mid-teens to up to 20% on net sales of TLANDO. Lipocine retains all rights for ex-US territories, and non TRT indications for TLANDO. Under the agreement, Antares Pharma will undertake all commercialization, post-marketing obligations, and sourcing of TLANDO in the U.S.

In addition, Lipocine has granted Antares Pharma an option to license, on or before March 31, 2022, TLANDO XR, a next-generation, potential once-daily oral product candidate for TRT, in the U.S.  TLANDO XR met primary and secondary regulatory end points for TRT in an earlier Phase 2 clinical study. Upon exercise of the TLANDO XR option, Lipocine is entitled to receive an additional $4.0 million in license fees, clinical and regulatory milestone payments of up to an aggregate of $35.0 million, and tiered royalties on net sales at rates ranging from the mid-teens to up to 20%. Antares Pharma will be responsible for development costs, regulatory filings, commercialization, and post-marketing commitments for TLANDO XR.
