RESEARCH TRIANGLE PARK, N.C., Aug. 14, 2025 (GLOBE NEWSWIRE) -- Fennec Pharmaceuticals Inc. (NASDAQ:FENC; TSX: FRX), a specialty pharmaceutical company, today reported its financial results for the second quarter ended June 30, 2025 and provided a business update.
“We are pleased to have delivered three consecutive quarters of strong performance, with second quarter revenue up 33% over the same quarter in 2024. This acceleration reflects significant progress in both large community practices and academic centers – driven by a completely overhauled go-to-market approach, increased awareness of the importance of preventing cisplatin-induced ototoxicity (CIO) and expanded patient support program offerings,” said Jeff Hackman, chief executive officer of Fennec Pharmaceuticals. “The results demonstrate the scalability of our model and the strong demand for PEDMARK® across key segments of the market. With the U.S. momentum for PEDMARK building, coupled with Norgine’s ex-U.S. PEDMARQSI® launches and results from the investigator-initiated clinical trial STS-J01 in Japan expected in the coming months, we believe the global opportunity for both patients and Fennec shareholders is significant.”
Business Highlights:
- Continued Growth Within Key PEDMARK® Accounts: In the second quarter, Fennec’s segmentation model and data-driven target lists enhanced field execution, yielding a mix of new and repeat customers, with notable growth across both large community and academic practices.
- A Large National Oncology Group Has Added PEDMARK® to its Formulary for Patients Under 40: This rapidly growing group includes numerous community-based oncology practices across the U.S. This decision reflects the growing recognition of the need to protect younger patients from cisplatin-induced hearing loss and signals momentum for broader adoption in community settings.
- NCODA PQI (Positive Quality Intervention) Issued for PEDMARK®: This recently published PQI aims to provide pharmacists, nurses, and oncologists with clinical data and guidance on the use, administration, and timing of PEDMARK to prevent platinum-induced ototoxicity in pediatric patients and the AYA population. NCODA PQIs are designed to help multidisciplinary oncology care teams manage patients on oral and IV cancer therapies.
- Quarter Over Quarter Growth in Enrollment in Fennec HEARS™ and Specialty Pharmacy Program: The newly revamped patient support program offerings is delivering improved experiences through strengthened HCP and patient services, expanded payer reimbursement support, and streamlined access to home nursing resources.
- Recent Issuance Further Strengthens Fennec’s Patent Portfolio: In May, the U.S. Patent and Trademark Office issued U.S. Patent 12,311,026 entitled “Pharmaceutical Composition Comprising Sodium Thiosulfate.” The patent claims cover the use of a broad range of stabilizers or a mixture of stabilizers for the pharmaceutical composition of sodium thiosulfate to reduce ototoxicity in a pediatric patient receiving a platinum-based therapeutic. Fennec currently has six FDA Orange Book listings providing U.S. patent protection for PEDMARK® until 2039 as well as global patents issued and pending globally.

Financial Results for the Second Quarter 2025 Ended June 30, 2025
- Net Product Sales – For the second quarter of 2025, the Company recorded net product sales of approximately $9.7 million compared to $7.3 million in the second quarter of 2024. The increase in sales is attributable to the expanded focus and growth in the AYA population, as well as the successful growth and retention of existing accounts within this population.
- Selling and Marketing Expenses – The Company recorded $4.4 million in selling and marketing expenses in the second quarter of 2025, compared to $4.6 million in the second quarter of 2024.
- General and Administrative (G&A) Expenses – The Company recorded $7.0 million in G&A expenses in the second quarter of 2025 compared to $6.9 million in the second quarter of 2024. The comparable quarter increase in expenses year over year is due to increased intellectual property expenses offset by decreased consulting fees related to the European commercialization. Additionally, there was approximately $1.5 million in non-cash stock-based compensation in the second quarter of 2025 compared to $0.9 million in the comparable quarter in 2024.
- Cash Position – Cash and cash equivalents were $18.7 million as of June 30, 2025, compared to $22.7 million as of March 31, 2025. The decrease in cash in the second quarter is primarily due to cash operating expenses, which are seasonally higher in the first half of the Company’s calendar year as a result of commercial and marketing spending patterns for 2025.

About Cisplatin-Induced Ototoxicity
Cisplatin and other platinum-based chemotherapies are widely used to treat solid tumors and have been vital in improving survival rates. Unfortunately, these life-saving treatments often result in permanent, irreversible hearing loss, also known as ototoxicity.i
Hearing loss from cisplatin treatment is not rare. Studies show that between 60-90% of patients treated with cisplatin may develop hearing loss, depending upon the dose and duration of chemotherapyii. Many of those treated with cisplatin will 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.iii Treatment-induced hearing loss can reduce quality of survivorship as it impacts many aspects of life, such as speech and language skills, academic performance, social-emotional development, career potential and the ability to live independently.iv,v While audiologic monitoring is recommended to help manage ototoxicity, it is currently underutilized in certain cancer patient populations.
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 1 month of age and older 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.
Additionally, PEDMARK is recommended for the adolescent and young adult (AYA) population by the National Comprehensive Cancer Network, or NCCN, with a 2A endorsement.
Approximately 500,000 patients in the U.S. are diagnosed annually with cancers that could be treated with a platinum-based chemotherapy. The incidence of ototoxicity depends upon the dose and duration of chemotherapy, and many of those treated will require lifelong hearing aids. Until the FDA approval of PEDMARK, there were no preventative agents for this hearing loss. Patients with hearing loss resulting from cancer treatment have a statistically significant worse quality of life compared with peers who have no hearing loss.vivii
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.
