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 RESEARCH TRIANGLE PARK, N.C. and UXBRIDGE, United Kingdom, March 17, 2024 (GLOBE NEWSWIRE) -- 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.” Moelis & Company LLC acted as financial advisor, and LaBarge Weinstein LLP acted as legal advisor to Fennec. Arnold & Porter acted as legal advisor to Norgine.

MINNEAPOLIS, March 12, 2024 (GLOBE NEWSWIRE) -- Panbela Therapeutics Inc. (Nasdaq: PBLA), (“Panbela”), a clinical stage company developing disruptive therapeutics for the treatment of patients with urgent unmet medical needs, today announced that it will host a conference call on March 26, 2024, at 4:30 PM Eastern Time to discuss results for its fourth quarter and year ended December 31, 2023. Conference Call Information Toll Free: 888-506-0062 International: 973-528-0011 Participant Access Code: 195310 Webcast Link: Conference Call Replay Information Toll Free: 877-481-4010 International: 919-882-2331 Replay Passcode: 49978 Webcast Replay: About Panbela’s Pipeline The pipeline consists of assets currently in clinical trials with an initial focus on familial adenomatous polyposis (FAP), first-line metastatic pancreatic cancer, neoadjuvant pancreatic cancer, colorectal cancer prevention and ovarian cancer. The combined development programs have a steady cadence of anticipated catalysts with programs ranging from pre-clinical to registration studies. Ivospemin (SBP-101) Ivospemin is a proprietary polyamine analogue designed to induce polyamine metabolic inhibition (PMI) by exploiting an observed high affinity of the compound for pancreatic ductal adenocarcinoma and other tumors. It has shown signals of tumor growth inhibition in clinical studies of metastatic pancreatic cancer patients, demonstrating a median overall survival (OS) of 14.6 months and an objective response rate (ORR) of 48%, both exceeding what is typical for the standard of care of gemcitabine + nab-paclitaxel suggesting potential complementary activity with the existing FDA-approved standard chemotherapy regimen. In data evaluated from clinical studies to date, ivospemin has not shown exacerbation of bone marrow suppression and peripheral neuropathy, which can be chemotherapy-related adverse events. Serious visual adverse events have been evaluated and patients with a history of retinopathy or at risk of retinal detachment will be excluded from future SBP-101 studies. The safety data and PMI pro in the previous Panbela-sponsored clinical trials provide support for continued evaluation of ivospemin in the ASPIRE trial. Flynpovi ™ Flynpovi is a combination of CPP-1X (eflornithine) and sulindac with a dual mechanism inhibiting polyamine synthesis and increasing polyamine export and catabolism. In a Phase III clinical trial in patients with sporadic large bowel polyps, the combination prevented > 90% subsequent pre-cancerous sporadic adenomas versus placebo. Focusing on FAP patients with lower gastrointestinal tract anatomy in the recent Phase III trial comparing Flynpovi to single agent eflornithine and single agent sulindac, FAP patients with lower GI anatomy (patients with an intact colon, retained rectum or surgical pouch), showed statistically significant benefit compared to both single agents (p≤0.02) in delaying surgical events in the lower GI for up to four years. The safety pro Flynpovi did not significantly differ from the single agents and supports the continued evaluation of Flynpovi for FAP. CPP-1X CPP-1X (eflornithine) is being developed as a single agent tablet or high dose powder sachet for several indications including prevention of gastric cancer, treatment of neuroblastoma and recent onset Type 1 diabetes. Preclinical studies as well as Phase I or Phase II investigator-initiated trials suggest that CPP-1X treatment may be well-tolerated and has potential activity.

Panbela’s lead assets are Ivospemin (SBP-101) and Flynpovi. Further information can be found at . Panbela’s common stock is listed on The Nasdaq Stock Market LLC under the symbol “PBLA”.
