Financial Results for the First Quarter 2022

• 
  Cash Position –
  
  Cash and cash equivalents were $18.3 million as of March 31, 2022. The decrease in cash and cash equivalents between March 31, 2022 and December 31, 2021, is the result of expenses related to the development and preparation of our New Drug Application (NDA) resubmission of PEDMARK™ and general and administrative expenses.
• 
  Research and Development (R&D) Expenses
  
  – R&D expenses were $1.4 million for the first quarter ended March 31, 2022 compared to $2.4 million for the same period in 2021. R&D expenses decreased by $1.0 million for the three months ended March 31, 2022 over the same period in 2021 as the Company’s development activities decreased Company’s as efforts on year over year basis were less focused on development and shifted towards pre commercialization activities.
• 
  General and Administrative (G&A) Expenses –
  
  G&A expenses were $2.1 million for the first quarter ended March 31, 2022, compared to $2.5 million for the same period in 2021.  The decrease in general and administrative expenses over same period in 2021 reflects select expenses associated with pre-commercialization not needing to be repeated as they were completed in 2021.
• 
  Net Loss –
  
  Net loss for the quarter ended March 31, 2022 was $3.7 million ($0.14 per share), compared to $4.7million ($0.18 per share) for the same period in 2021.

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.
