FENNEC PHARMACEUTICALS ANNOUNCES FISCAL YEAR 2021 FINANCIAL RESULTS AND PROVIDES BUSINESS UPDATE

~ Resubmission of NDA for PEDMARKTM Targeted for the First Quarter of 2022 ~

~ Company has Approximately $21.1 Million in Cash and $5 Million of Funded Debt ~

Research Triangle Park, NC, February 28, 2022 – Fennec Pharmaceuticals Inc. (NASDAQ:FENC; TSX: FRX), a specialty pharmaceutical company focused on the development of PEDMARKTM (a unique formulation of sodium thiosulfate (STS)) for the prevention of platinum-induced ototoxicity in pediatric patients, today reported its financial results for the fiscal year ended December 31, 2021 and provided a business update.

“We expect to resubmit the New Drug Application (NDA) for PEDMARKTM to the FDA during the first quarter of 2022,” said Rosty Raykov, chief executive officer of Fennec Pharmaceuticals. “We remain committed to making PEDMARK commercially available to children and young adults receiving cisplatin chemotherapy, who currently have no approved therapies for ototoxicity.”

Financial Results for the Fourth Quarter and Fiscal Year Ended December 31, 2021

  • Cash Position – There was a $9.2 million decrease in cash and cash equivalents between December 31, 2021 and December 31, 2020. The net decrease was the result of cash operating expenses, offset by the $5.0 million received from the Bridge Bank Loan Security Agreement and some negligible amounts received from option exercises. During the period ended December 31, 2021, cash for operations was used mainly on pre-commercialization activities for PEDMARKand regulatory submission activities relating to the pending resubmission of the NDA.
  • Research and Development (R&D) Expenses – R&D expenses were $0.5 and $5.0 million, respectively, for the fourth quarter and year ended December 31, 2021, compared to $1.2 million and $5.1 million for the same period in 2020.
  • General and Administrative (G&A) Expenses – G&A expenses were $3.7 million and $12.2 million, respectively, for the fourth quarter and year ended December 31, 2021, compared to $2.3 million and $13.0 million, respectively for the same periods in 2020. The annual decrease in G&A was largely due to commercialization readiness expenses for PEDMARKin 2020, which did not need to be repeated in 2021. The fourth quarter increase in 2021 over the same time period in 2020 arose from non-cash equity grants and our pre-commercialization activities for PEDMARK as the Company prepared for potential NDA approval by the FDA in November 2021.
  • Net Loss – Net losses for the fourth quarter and year ended December 31, 2021 of $4.4 million ($0.18 per share) and $17.3 million ($0.67 per share), respectively, compared to $3.2 million ($0.13 per share) and $18.1 million ($0.76 per share), respectively, for the same periods in 2020.
  • Financial Guidance – The Company believes its cash and cash equivalents on hand as of December 31, 2021 will be sufficient to fund the Company’s planned activities for 2022 including NDA resubmission and commercial readiness activities.

About PEDMARK™

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

In the U.S. and Europe, it is estimated that, annually, over 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 cooperative groups in two Phase 3 clinical studies of survival and reduction of ototoxicity, The Clinical Oncology Group Protocol 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, and medulloblastoma.  SIOPEL 6 enrolled only hepatoblastoma patients with localized tumors.

The Marketing Authorization Application (MAA) for sodium thiosulfate (tradename PEDMARQSI) is currently under evaluation by the European Medicines Agency (EMA).  PEDMARK has received Breakthrough Therapy and Fast Track Designation by the FDA in March 2018.
