• PEDMARK^® Net Product Revenue of $6.5 Million, a 96% Increase Compared to Second Quarter 
  
• Strong Commercial Uptake Underscoring Significant Unmet Medical Need 
• Received Approval in October 2023 by the Medicines and Healthcare Products Regulatory Agency (MHRA) in the U.K. for PEDMARQSI 
• Management to Host Conference Call Today at 8:30 a.m. ET 

RESEARCH TRIANGLE PARK, N.C., Nov. 06, 2023 (GLOBE NEWSWIRE) -- Fennec Pharmaceuticals Inc. (NASDAQ:FENC; TSX: FRX), a commercial stage specialty pharmaceutical company, today reported its financial results for the third quarter ended September 30, 2023 and provided a business update.

“We continued to see strong commercial performance with PEDMARK^® in the third quarter demonstrated by net product revenue of $6.5 million representing 96% quarter over quarter growth. PEDMARK^® addresses a significant unmet medical need in the pediatric oncology community, and we expect to continue building upon our commercial momentum through expanding the prescriber base and increasing the utilization of the earlier endorsement from the NCCN for PEDMARK^® in the adolescent and young adult (AYA) population,” said Rosty Raykov, chief executive officer of Fennec Pharmaceuticals. “Further, we are pleased with the steady progress that we are making preparing for the launch of PEDMARQSI in Europe, including the recent regulatory approval in the U.K. by the MHRA, as we continue to evaluate the best commercial pathway for the Company in Europe.”

Financial Results for the third Quarter 2023

• Net Sales – The company recorded net product sales of $6.5 million in the third quarter of 2023 compared to net product sales of $3.3 million in the second quarter of 2023. The Company had gross profit of $6.2 million for the third quarter of 2023. The increase in sales reflects strong growth in new patient starts and account adoption.
  
  
• Cash Position – Cash and cash equivalents were $12.4 million on September 30, 2023. The decrease in cash and cash equivalents between September 30, 2023, and December 31, 2022, is the result of cash outlays for operating expenses related to the promotion and marketing of PEDMARK^® and general and administrative expenses, which were offset by cash inflows primarily from product sales. We anticipate that our cash, cash equivalents and investment securities as of September 30, 2023, when coupled with PEDMARK revenue assumptions will be sufficient to fund our planned operations for at least the next twelve months.
  
  
• Research and Development (R&D) Expenses – Research and development expenses decreased by $0.8 million for the three months ended September 30, 2023, compared to the same period in 2022. The Company’s research and development activities for the quarter ended September 30, 2023 consisted of costs associated with investigator initiated clinical trials. During the same period in 2022 and prior to approval of PEDMARK^®, manufacturing costs pertaining to PEDMARK^® were allocated to R&D expense in the period incurred, and following approval are reflected in inventory.
  
  
• Selling and Marketing Expenses – Selling and marketing expenses include remuneration of our sales and marketing employees, dollars spent on marketing campaigns (sponsorships, trade shows, presentations, etc.), and any activities to support marketing and sales activities. Selling and marketing expenses for the third quarter of 2023 were $3.4 million compared to $2.3 million in the second quarter of 2023 as the Company increased marketing in the U.S. and pre-commercialization activities in Europe.
  
  
• General and Administrative (G&A) Expenses – For the three-month period ended September 30, 2023, G&A expenses decreased by $3.2 million over the same period in 2022. Further, G&A expenses decreased by $1.7 million compared to the second quarter of 2023. The decrease in G&A was primarily because of decreases in non-cash employee remuneration which accounted for $1.0 million of the decrease over same period in 2022. There was a reduction in legal expenses of $0.7 million for the quarter ended September 30, 2023 over the same period in 2022.
  
  
• Net Loss – Net loss for the quarter ended September 30, 2023, was $1.9 million ($0.07 per share), compared to $8.1 million ($0.31 per share) for the same period in 2022.

About Cisplatin-Induced Ototoxicity

Cisplatin and other platinum compounds are essential chemotherapeutic agents for the treatment of many pediatric 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 only therapeutic agent with proven efficacy and safety data with an established dosing paradigm, across two open-label, randomized Phase 3 clinical studies, the Clinical Oncology Group (COG) Protocol ACCL0431 and SIOPEL 6.

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.
