/EIN News/ -- RESEARCH TRIANGLE PARK, N.C., March 10, 2025 (GLOBE NEWSWIRE) -- Fennec Pharmaceuticals Inc. (NASDAQ:FENC; TSX: FRX), a specialty pharmaceutical company, today reported its financial results for the fiscal year ended December 31, 2024 and provided a business update.

“2024 marked the beginning of a foundational transformation for Fennec, setting the stage for the PEDMARK^® strategy that we are utilizing throughout 2025 to realize our next phase of growth. With key management and commercial hires in Q3 and Q4, we strengthened our leadership team and with this enhanced expertise, we are now well-positioned to drive execution and excellence in the field. We are seeing encouraging momentum in early 2025, particularly with adoption by academic institutions and new patient segments, reinforcing the value and need for PEDMARK^®,” said Jeff Hackman, chief executive officer of Fennec Pharmaceuticals. “Global access to PEDMARK^® has also expanded meaningfully, with recent PEDMARQSI^® commercial launches in the United Kingdom and Germany in 2025. With the right foundational strategies now in place, we are confident that our strong and focused execution will translate into significant shareholder value in 2025 and beyond.”

Business Highlights:

• U.S. Clinical Compendia Update: All medical compendia have incorporated Fennec’s clinical updates, and AHFS, the largest online platform for pharmacists, has updated its content to reflect and differentiate PEDMARK^® in accordance with its labeling. We also continue to advance our efforts to have PEDMARK^® added to the NCCN Drug and Biologics Compendium^®, a key step in further expanding access and reimbursement pathways.
  
• PEDMARQSI Commercial Launch in Europe: In December 2024, Norgine received positive guidance from National Institute for Health and Care Excellence (NICE) recommending PEDMARQSI^® for the prevention of cisplatin-induced hearing loss in patients (aged 1 month to 17 years) with localized, non-metastatic, solid tumors and PEDMARQSI^® is currently available in the U.K. In February 2025, Norgine announced that it has commercially launched PEDMARQSI^® in Germany. Both milestones mark an important step in achieving Fennec’s mission of expanding access to PEDMARQSI^® to cancer patients across the globe at risk of hearing loss.
  
• Ex-U.S. Opportunities for PEDMARK: In Japan, the investigator-initiated clinical trial (STS-J01) in Japan evaluating PEDMARK fully enrolled in Q4 2024 and the results of the trial are expected in the second half of 2025 with the potential evaluation for registration of PEDMARK^® in Japan thereafter. Further, Fennec has partnered with Inpharmus, formerly named TRPharm İlaç Sanayi Ticaret A.Ş. and TRPharm FZ-LLC, for the distribution of PEDMARK^® in Turkey and Gulf Cooperation Council Countries.
  
• Early Repayment of $13 Million of the Company’s Approximately $32 Million Outstanding Convertible Debt Facility: In December 2024, Fennec announced the early partial repayment of a significant portion of its debt to Petrichor in a financial and strategic action that optimizes the Company’s balance sheet and overall capital structure, while effectively saving approximately $1.5 million in future annual interest payments and eliminating potential dilutive shares.
  

Financial Results for the Fourth Quarter and Full Fiscal Year Ended December 31, 2024

• Net Product Sales – For the fourth quarter of 2024, the Company recorded net product sales of $7.9 million compared to $7.0 million in the third quarter of 2024, representing an increase of approximately 13%. For the full fiscal year (FY) 2024, the Company recorded $29.6 million compared to $21.3 million in 2023, representing an increase of approximately 40%. The increase in sales in both the quarter and year reflects strong growth in accounts and increased penetration in the AYA market opportunity.
  
• Cash Position – Cash and cash equivalents were $26.6 million as of December 31, 2024. Of note, for the fourth quarter of 2024, our cash flow from operations decreased by $0.6 million. For the FY 2024, there was a $13.4 million increase in cash and cash equivalents between December 31, 2023 and December 31, 2024. The increase in cash was primarily due to the $43 million in upfront cash from the Norgine transaction and cash collected from product sales offset by operating expenses and the $13 million convertible debt paydown in December 2024.
  
• Selling and Marketing Expenses – The Company recorded $3.9 million in selling and marketing expenses in the fourth quarter of 2024 compared to $4.6 million in the third quarter of 2024. For the FY 2024, the Company recorded $18.4 million in selling and marketing compared to $12.1 million in fiscal year 2023. The increase is largely related to increased payroll and additional marketing expenses in the comparable periods as we focused on expanding our outreach to community oncology centers and the adolescent and young adult (AYA) population.
• General and Administrative (G&A) Expenses – The Company recorded $4.1 million in G&A expenses fourth quarter of 2024 compared to $7.0 million in the third quarter of 2024. For the FY 2024, the Company recorded $23.1 million in G&A expenses compared to $20.6 million in fiscal year 2023. For the fourth quarter of 2024, G&A expenses decreased due largely to lower cash based stock compensation and a one-time severance payment related to the previous CEO in the third quarter. For the full year G&A expenses were higher both due to European pre-commercialization related expenses, expenses associated with the Norgine transaction and intellectual property expenses related to ongoing litigation.

About Cisplatin-Induced Ototoxicity
Cisplatin and other platinum compounds are essential chemotherapeutic agents for the treatment of many malignancies. Unfortunately, platinum-based therapies can cause ototoxicity, or hearing loss, which is permanent, irreversible, and particularly harmful to the survivors of pediatric cancer.ⁱ

The incidence of ototoxicity depends upon the dose and duration of chemotherapy, and many of these children require lifelong hearing aids or cochlear implants, which can be helpful for some, but do not reverse the hearing loss and can be costly over time.ⁱⁱ Infants and young children that are affected by ototoxicity at critical stages of development lack speech and language development and literacy, and older children and adolescents often lack social-emotional development and educational achievement.ⁱⁱⁱ

PEDMARK^® (sodium thiosulfate injection)
PEDMARK^® is the first and only U.S. Food and Drug Administration (FDA) approved therapy indicated to reduce the risk of ototoxicity associated with cisplatin treatment in pediatric patients with localized, non-metastatic, solid tumors. It is a unique formulation of sodium thiosulfate in single-dose, ready-to-use vials for intravenous use in pediatric patients. PEDMARK is also the first and only therapeutic agent with proven efficacy and safety data with an established dosing regimen, across two open-label, randomized Phase 3 clinical studies, the Children’s Oncology Group (COG) Protocol ACCL0431 and SIOPEL 6.

As a reminder, PEDMARK is indicated to reduce the risk of ototoxicity associated with cisplatin in pediatric patients 1 month of age and older with localized, non-metastatic solid tumors. PEDMARK is recommended for the AYA population by the National Comprehensive Cancer Network, or NCCN, with a 2A endorsement.

In the U.S. and Europe, it is estimated that, annually, more than 10,000 children may receive platinum-based chemotherapy. The incidence of ototoxicity depends upon the dose and duration of chemotherapy, and many of these children require lifelong hearing aids. There is currently no established preventive agent for this hearing loss and only expensive, technically difficult, and sub-optimal cochlear (inner ear) implants have been shown to provide some benefit. Infants and young children that suffer ototoxicity at critical stages of development lack speech language development and literacy, and older children and adolescents lack social-emotional development and educational achievement.

PEDMARK has been studied by co-operative groups in two Phase 3 clinical studies of survival and reduction of ototoxicity, COG ACCL0431 and SIOPEL 6. Both studies have been completed. The COG ACCL0431 protocol enrolled childhood cancers typically treated with intensive cisplatin therapy for localized and disseminated disease, including newly diagnosed hepatoblastoma, germ cell tumor, osteosarcoma, neuroblastoma, medulloblastoma, and other solid tumors. SIOPEL 6 enrolled only hepatoblastoma patients with localized tumors.

Indications and Usage
PEDMARK^® (sodium thiosulfate injection) is indicated to reduce the risk of ototoxicity associated with cisplatin in pediatric patients 1 month of age and older with localized, non-metastatic solid tumors.

Limitations of Use
The safety and efficacy of PEDMARK have not been established when administered following cisplatin infusions longer than 6 hours. PEDMARK may not reduce the risk of ototoxicity when administered following longer cisplatin infusions, because irreversible ototoxicity may have already occurred.

Important Safety Information
PEDMARK is contraindicated in patients with history of a severe hypersensitivity to sodium thiosulfate or any of its components.

Hypersensitivity reactions occurred in 8% to 13% of patients in clinical trials. Monitor patients for hypersensitivity reactions. Immediately discontinue PEDMARK and institute appropriate care if a hypersensitivity reaction occurs. Administer antihistamines or glucocorticoids (if appropriate) before each subsequent administration of PEDMARK. PEDMARK may contain sodium sulfite; patients with sulfite sensitivity may have hypersensitivity reactions, including anaphylactic symptoms and life-threatening or severe asthma episodes. Sulfite sensitivity is seen more frequently in people with asthma.

PEDMARK is not indicated for use in pediatric patients less than 1 month of age due to the increased risk of hypernatremia or in pediatric patients with metastatic cancers.

Hypernatremia occurred in 12% to 26% of patients in clinical trials, including a single Grade 3 case. Hypokalemia occurred in 15% to 27% of patients in clinical trials, with Grade 3 or 4 occurring in 9% to 27% of patients. Monitor serum sodium and potassium levels at baseline and as clinically indicated. Withhold PEDMARK in patients with baseline serum sodium greater than 145 mmol/L.

Monitor for signs and symptoms of hypernatremia and hypokalemia more closely if the glomerular filtration rate (GFR) falls below 60 mL/min/1.73m².

Administer antiemetics prior to each PEDMARK administration. Provide additional antiemetics and supportive care as appropriate.

The most common adverse reactions (≥25% with difference between arms of >5% compared to cisplatin alone) in SIOPEL 6 were vomiting, nausea, decreased hemoglobin, and hypernatremia. The most common adverse reaction (≥25% with difference between arms of >5% compared to cisplatin alone) in COG ACCL0431 was hypokalemia.
