Ligand Earns $1 Million Milestone Payment Triggered by FDA Approval of Merck’s NOXAFIL® (posaconazole) Injection for Intravenous Use, a New Captisol-enabled Formulation

SAN DIEGO-- Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) announces that it has earned a $1 million milestone payment as a result of the recent U.S. Food and Drug Administration (FDA) approval of Merck’s NOXAFIL® (posaconazole) injection (18 mg/mL). This is a new Captisol®-enabled formulation of NOXAFIL for intravenous (IV) use. Ligand will sell Captisol to Merck for this product under a commercial supply agreement.

“We congratulate the project team at Merck on this important advancement in the treatment of invasive fungal infections,” said John Higgins, President and Chief Executive Officer of Ligand Pharmaceuticals.

“Ligand's business is thriving with the continued success of our partners with late-stage clinical and regulatory events. This is the second new product expected to be made available in 2014 following the launch of Duavee® last month by Pfizer and three additional Ligand-partnered programs are pending approvals in 2014,” continued Higgins. “Captisol is a proven formulation that is garnering more interest by prospective customers and partners given the technology’s elevated profile.”

NOXAFIL injection for intravenous use is indicated for prophylaxis of invasive Aspergillus and Candida infections in patients who are at high risk of developing these infections due to being severely immunocompromised, such as hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD) or those with hematologic malignancies with prolonged neutropenia (low white blood cell counts) from chemotherapy. NOXAFIL injection is indicated in patients 18 years of age and older.

The availability of a NOXAFIL formulation for intravenous administration is particularly important for those patients who may benefit from or require intravenous therapy, or who might not be able to take an oral formulation. Merck’s antifungal agent is also marketed as NOXAFIL (100 mg) delayed-release tablets and NOXAFIL (40 mg/mL) oral suspension.
