RESEARCH TRIANGLE PARK, N.C., Aug. 13, 2024 (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, 2024, and provided a business update.

"We continued to execute well in the second quarter and are encouraged by the early third quarter momentum of PEDMARK^® within the community oncology and the adolescent and young adult (AYA) population," said Jeff Hackman, chief executive officer of Fennec Pharmaceuticals. "I am excited to join Fennec and take on the challenge of guiding the Company towards greater commercial success. We will focus on expanding our initial outreach to community oncology centers and the adolescent and young adult (AYA) population, who can greatly benefit from our treatments. By reaching more patients in these critical areas, I am confident that we can drive growth and make a significant impact in improving patient outcomes."

Recent Developments and Highlights:

Appointed Jeffery Hackman as Fennec's New CEO and Board Member: Jeff has been appointed as the new Chief Executive Officer and a member of the Board of Directors. With a passion for patients and a track record of success, Jeff is poised to make an immediate impact by driving Fennec's strategic direction and leading the Company into its next exciting phase of growth. Rosty Raykov will continue to contribute as a member of the Board of Directors.

NCCN AYA Guidelines Updated: The NCCN Adolescent and Young Adult (AYA) Guidelines have been modified to remove "pediatric" specific wording. This change is instrumental in solidifying PEDMARK's position for access to a broader patient population to prevent ototoxicity, both with payers and providers.

Participation in Key Scientific Meetings: During the second quarter, Fennec actively participated in key regional and national scientific meetings, including the American Society of Clinical Oncology (ASCO), the Advanced Practice Providers Oncology Summit (APPOS), and the Oncology Nursing Society (ONS) annual meetings. These engagements underscore our commitment to advancing oncology care and fostering strong relationships within the healthcare community.

Financial Results for the Second Quarter 2024

Net Sales – The Company recorded net product sales of $7.3 million for the three-month period ended June 30, 2024, compared to $3.3 million in net sales for the same period in 2023.

Cash Position – Cash and cash equivalents were $43.1 million on June 30, 2024. The increase in cash and cash equivalents between June 30, 2024, and December 31, 2023, is the result of approximately $43 million from the Norgine transaction and cash inflows from net sales offset by cash outlays for operating expenses related to the promotion of our product, selling and marketing expenses and general and administrative expenses. We anticipate that our cash, cash equivalents and investment securities as of June 30, 2024 will be sufficient to fund our planned operations for at least the next twelve months

Selling and Marketing Expenses –The Company recorded $4.7 million in selling and marketing expenses for the period ended June 30, 2024, compared to $2.3 million for the same period in 2023. The increase is largely related to additional selling and marketing expenses as the Company expanded its focus in the AYA and community oncology population during 2024.

General and Administrative (G&A) Expenses – G&A expenses increased by $1.4 million over the same period in 2023 to $6.9 million. There was an increase in consulting, and professional costs related to European pre-commercialization related expenses in the 2024 period over the comparable period. European related expenses are expected to wind down after Q2 2024 with the announcement of the Norgine transaction in March 2024.

Net Earnings – Net loss for the quarter ended June 30, 2024 was $5.6 million (basic and diluted loss of $0.20 per share) compared to a net loss of $5.4 million (basic and diluted loss of $0.21 per share) for the same period in 2023.

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.¹

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.² 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.³

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.⁷ 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.
