• In December 2016, Lancet Oncology published the results of COGACCL0431.

Key Milestones for 2017

• Results from SIOPEL 6 on hearing efficacy is expected to be announced in the fourth quarter of 2017.

Financial Update

The selected financial data presented below is derived from our audited condensed consolidated financial statements which were prepared in accordance with U.S. generally accepted accounting principles.  The complete audited consolidated financial statements for the period ended December 31, 2016 and management’s discussion and analysis of financial condition and results of operations will be available via www.sec.gov and www.sedar.com. All values are presented in thousands unless otherwise noted.

The Company reported a net loss from operations of $1.1 million (which excludes an immaterial non-cash gain on derivatives) for the three months ended December 31, 2016, compared to a net loss from operations of $0.5 million (excluding the non-cash gain of $0.01 million) in 2015. Research and development expenses totaled $0.2 million for the three months ended December 31, 2016, as compared to a $0.07 million in the same period in 2015 as the Company increased drug manufacturing expense. General and administrative expenses increased by $0.5 million in the three months ended December 31, 2016, as compared to the same period in 2015. The increase relates to non-cash equity based compensation for directors and officers, the extension of expiration dates on various prior option issuances to officers and directors and increased remuneration for officers and directors.

Total operating expenses were $2.9 million for the year ended December 31, 2016 and $1.9 million for the year ended December 31, 2015. The increase in net loss from operations excluding the non-cash impact of derivatives was due to both an increase in research and development expenses and general and administrative expenses. Research and development expenses were higher in fiscal 2016, as compared to fiscal 2015 primarily due to the preparation for the manufacturing of registration batches upon release of the study results from SIOPEL 6 in late 2017.

The $0.80 million increase in general and administrative expenses are attributed to a rise in compensation to officers, directors and key contract employees. Most of this increase relates to non-cash equity based compensation that was granted and vested during the year. Of the $0.70 million issued in equity based compensation, $0.35 million of that relates to expense recognized with extending the expiration dates of existing options issued to executives and directors. The rest relates to increases in remuneration paid to officers and directors as the Company moved to brings its compensation for key individuals in line with industry benchmarks.

Other income fell by $1.2 million as a result of the expiration of all remaining derivative warrants carried on the books. The company has a very small number of derivative options outstanding. Future changes in the valuation associated with these options are not expected to have a significant impact on the Company’s financial statements for the remaining life of these derivatives.

The Company completed the sale of certain intellectual property, data and other assets related to Eniluracil and Adh-1 for gross proceeds of $40. Interest income increased slightly in fiscal 2016, as compared to 2015 due to a higher average cash balance for the comparable periods.

The $3.0 million increase in cash and cash equivalents between December 31, 2016 and December 31, 2015 is due to the $5.0 million equity financing completed in May 2016, and the $0.1 million cash proceeds from the exercise of 67 warrants offset by clinical trial expenses related to our Phase III study of STS, the increase in regulatory and manufacturing activities for STS and our general and administrative expenses.

The decrease in other current assets between December 31, 2015 and December 31, 2016 relates to a reduction in pre-paid Director’s and Officer’s Insurance over the prior year. Current liabilities decreased primarily due to a write-off of old payables which had become statute barred. The Company wrote off approximately $0.08 million of payables which has become statute barred.

Working capital increased between December 31, 2016 and December 31, 2015 by $2.9 million. The increase was a result of a private placement funding in addition to various warrant and option exercises in 2016. These cash inflows were offset by cash expenditures related to our clinical trials, the commercial development of STS and general and administrative expenses.

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. and Europe there is estimated that over 10,000 children are diagnosed with local cancers that may receive platinum based chemotherapy.   Localized cancers that receive platinum agents may have overall survival rates of greater than 80% further emphasizing the quality of life after treatment. 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.
