Financial Update

The selected financial data presented below is derived from our unaudited condensed consolidated financial statements which were prepared in accordance with U.S. generally accepted accounting principles. The complete interim consolidated financial statements for the period ended September 30, 2015 and management’s discussion and analysis of financial condition and results of operations will be available viawww.sec.gov and www.sedar.com. All values are presented in thousands unless otherwise noted.

Research and development expenses for the three months ended September 30, 2015 were in line with those in the comparable period in 2014 as the Company’s focus continued to be solely on STS development. Research and development costs are impacted by the clinical support costs associated with the number of patients enrolled and participating in the trial during the financial period.

General and administrative expenses were down sharply for the three month period ended September 30, 2015 as compared to the same period in 2014 primarily as a result of a large reduction in equity based compensation.

The Company recorded an unrealized gain on derivatives of $216 in the three months ended September 30, 2015 compared to the same three months ended September 30, 2014 where there was an unrealized gain of $619 on derivative valuation and a realized gain of $379 on derivative settlement. These derivatives have been recorded at their fair value as a liability at issuance and will continue to be re-measured at fair value as a liability at each subsequent balance sheet date. Any change in value between reporting periods will be recorded as an unrealized gain/(loss). These warrants will continue to be reported as a liability until such time as they are exercised or expire. The fair value of these warrants is estimated using the Black-Scholes option-pricing model.

Total operating expenses were $1,339 for the nine-months ended September 30, 2015 and approximately $2,086 for the nine-months ended September 30, 2014. Research and development expenses were comparable for the same period as the Company’s focus was solely STS. There was a significant decrease in general and administrative expense due primarily to a reduction in non-cash expenses associated with the issuance of stock options in 2014.

Cash and cash equivalents were $1,366 at September 30, 2015 and $2,307 at December 31, 2014. The decrease in cash and cash equivalents between September 30, 2015 and December 31, 2014 is due to clinical trial expenses related to our Phase III study of STS and our general and administrative expenses offset by the exercise of options and warrants during the fiscal year. The Company received approximately $0.5 million in cash from the exercise of options and warrants to purchase an aggregate of approximately of 347 of our common shares.

At September 30, 2015, the Company had working capital balance totaling approximately $1.1 million compared to $1.9 million as of December 31, 2014.

About Sodium Thiosulfate (STS)

Cisplatin and other platinum compounds are essential chemotherapeutic components for many pediatric malignancies. Unfortunately platinum-based therapies cause ototoxicity in many patients, and are particularly harmful to the survivors of pediatric cancer.

In the U.S., it is estimated that over 2,000 children are diagnosed with local cancers that may receive platinum based chemotherapy and globally over 5,000. The incidence of hearing loss in these children 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 at critical stages of development lack speech language development and literacy, and older children and adolescents lack social-emotional development and educational achievement.

STS 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 are closed to recruitment. The COG ACCL0431 protocol enrolled one of five 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.
