Medexus has acquired exclusive rights to commercialize Gleolan in the United States,
complementing Medexus’s existing rights to Gleolan in Canada

Gleolan is an optical imaging agent currently indicated in the United States in patients with glioma
as an adjunct for the visualization of malignant tissue or tumor tissue during surgery

Gleolan generated $3-4 million U.S. net sales in the fourth calendar quarter of 2021

TORONTO and CHICAGO, March 01, 2022 (GLOBE NEWSWIRE) -- Medexus Pharmaceuticals (Medexus) (TSX: MDP) (OTCQX: MEDXF) is pleased to announce that its U.S. subsidiary, Medexus Pharma (Medexus US), has acquired the exclusive right to commercialize Gleolan in the United States from NX Development Corp. (NXDC), the U.S. subsidiary of photonamic GmbH & Co. (Photonamic). This transaction extends Medexus’s strong relationship with Photonamic and complements Medexus’s existing commercialization rights to Gleolan in Canada, where Medexus recently launched the product. Using information provided by NXDC, Medexus estimates that Gleolan generated U.S. net sales of $3 million to $4 million in the fourth calendar quarter of 2021. Based on Medexus’s evaluation of Gleolan’s effectiveness, Medexus is confident in Gleolan’s prospects in both Canada and the United States, and expects strong sales and institutional uptake in both markets. Medexus and NXDC plan to work together closely to ensure a seamless transition for existing customers.

Under the terms of Medexus’s new license, supply, and distribution agreement, Medexus will commercialize Gleolan in the United States and will pay NXDC annual royalty payments (tiered based on net sales relative to an annual minimum baseline and net of supply price paid) and periodic low- to mid-single-digit-million dollar milestone payments (including an upfront payment, two payments triggered by passage of time, and three payments triggered by achievement of net sales thresholds). NXDC will supply Gleolan to Medexus and will remain the sponsor of the new drug application for Gleolan on file with the U.S. Food and Drug Administration (FDA). This transaction will allow NXDC, as sponsor, to continue the company’s important research and development activities, including pursuit of additional indications for Gleolan. Medexus US’s exclusive commercialization rights extend to one additional indication, meningioma, with the opportunity to negotiate commercialization rights to future indications. The initial term of the parties’ arrangement will extend through and including March 31, 2028 with successive two-year extension terms thereafter.

“We are thrilled to license Gleolan in the United States and continue to drive our business forward,” said Ken d’Entremont, Medexus’s chief executive officer. “We believe Gleolan has a bright future and testing is currently underway for its use for meningioma, which would be a new indication.” Mr d’Entremont then continued, “This product fits extremely well into our portfolio. We are already very familiar with Gleolan given our successful launch of the product in Canada early last year. Extending our Gleolan distribution rights into the United States will allow us to continue developing our U.S. operations. We expect this product will both grow our U.S. revenues and allow us to put in place an infrastructure that will also support our U.S. launch of Treosulfan planned for later this year, assuming FDA approvals have been obtained.”

About Gleolan

Gleolan (aminolevulinic acid hydrochloride or ALA HCl) is an FDA-approved optical imaging agent indicated in patients with glioma (suspected World Health Organization Grades III or IV on preoperative imaging) as an adjunct for the visualization of malignant tissue during surgery. The FDA has granted Gleolan orphan drug designation through June 2024.

Gleolan makes high-grade gliomas (malignant, rapidly progressive brain tumors) fluoresce under a particular form of fluorescent blue light. Gleolan is a powder and is administered to patients as an oral solution. After administration, when the brain is exposed to blue light during surgery, areas within the tumor glow pink or red in contrast to healthy brain tissue which appears blue. This assists neurosurgeons in better visualizing these gliomas to facilitate more complete removal.

Surgeons using fluorescence-guided surgery with Gleolan demonstrated significant improvement in extent of resection when compared to procedures using white light. NXDC estimates that to date ALA HCl has been used in over 42 countries for over 100,000 patients worldwide.

The American Society of Clinical Oncology estimated that in 2021 approximately 24,500 adults in the United States would be diagnosed with primary cancerous tumors of the brain and spinal cord. According to the American Association of Neurological Surgeons, glioblastoma is the most common malignant central nervous system tumor, accounting for 47.7% of all diagnosed cases, and has an incidence of 3.21 per 100,000 population.
