Agreement pairs Norgine’s commercial expertise and leading European footprint with PEDMARQSI^®, the first and only approved therapy in the European Union and U.K. for reducing the risk of cisplatin-induced hearing loss in pediatric patients with localized, non-metastatic solid tumors

Fennec will receive €40 million in upfront and up to €210 million in additional commercial and regulatory milestones, and tiered royalties up to the mid-twenties

Enhances Norgine’s commitment to bringing transformative therapies to patients in Europe, U.K., Australia, and New Zealand who currently do not have access to a therapy to treat this life altering condition

Fennec Pharmaceuticals Inc. (NASDAQ: FENC; TSX: FRX), a commercial stage specialty pharmaceutical company, and Norgine, a leading European specialist pharmaceutical company, today announced an exclusive licensing agreement under which Norgine will commercialize PEDMARQSI^® in Europe, Australia and New Zealand. PEDMARQSI is the first and only approved therapy in the EU and U.K. for the prevention of ototoxicity (hearing loss) induced by cisplatin chemotherapy in patients 1 month to < 18 years of age with localized, non-metastatic solid tumors.

Under the terms of the licensing agreement, Fennec will receive €40 million in upfront consideration and up to €210 million in additional commercial and regulatory milestone payments and double-digit tiered royalties on net sales of PEDMARQSI in the licensed territories up to the mid-twenties. Norgine will be responsible for all commercialization activities in the licensed territories and will hold all marketing authorizations in the licensed territories.

It is estimated that more than 5,000 pediatric patients annually are eligible for platinum-based chemotherapy in Europe. PEDMARQSI was granted EU marketing authorization by the European Commission in June 2023, and received UK approval from the MHRA in October 2023. Approvals were based on safety and efficacy data from two open-label, randomized Phase 3 trials, SIOPEL 6 (pivotal) and Clinical Oncology Group [COG] Protocol ACCL0431. The studies compared PEDMARQSI plus cisplatin-based regimens to cisplatin-based regimens alone for the reduction of cisplatin-induced hearing loss in pediatric patients. PEDMARQSI holds eight years plus two years of data and market protection in Europe based on its Pediatric Use Marketing Authorization. Approval in Switzerland, Australia and New Zealand will also be pursued.

The first study (SIOPEL-6) involved 114 children with hepatoblastoma (a cancer of the liver), with an average age of about 19 months. The results showed that 35% (20 out of 57) of children who received PEDMARQSI 6 hours after each dose of cisplatin developed hearing loss compared with 67% (35 out of 52) of children who only received cisplatin. The second study involved 125 children aged 1 month to 18 years with different types of cancer, including hepatoblastoma, neuroblastoma (a cancer of immature nerve cells) and tumours of the central nervous system. The study found that hearing loss was experienced by 29% (14 out of 49) of children who received PEDMARQSI after each cisplatin dose compared with 56% (31 out of 55) of those who received only cisplatin.

“We are delighted to partner with Norgine, who shares our belief in the potential of PEDMARQSI to mitigate the risk of permanent and irreversible hearing loss that can occur in pediatric patients treated with cisplatin. Further, this partnership is an important step in achieving our mission of expanding PEDMARQSI to patients across the globe who are at risk of suffering from cisplatin-induced ototoxicity,” said Rosty Raykov, Chief Executive Officer of Fennec Pharmaceuticals. “From a deal perspective, the terms provided us many important benefits, including an upfront payment further solidifying our balance sheet, attractive economic terms providing meaningful participation in the ex-US success of PEDMARQSI and an experienced partner to successfully launch PEDMARQSI in the licensed territory.”

Chris Bath, Chief Executive Officer of Norgine, said, “We are thrilled to announce our partnership with Fennec, to bring this vital medicine to pediatric patients who are being treated with cisplatin, across Europe and ANZ. We look forward to working with the Fennec team and launching PEDMARQSI in our territories in the coming months, establishing it as the standard of care in this critical patient population with high unmet need. This important milestone for our company builds on our 30-year track record of creating partnerships of enduring value and further underscores Norgine’s position as the specialty pharma partner of choice across Europe and ANZ.”
