Sophiris Bio Reports Fourth Quarter 2018 and Year-end Financial Results and Recent Corporate Highlights
SAN DIEGO and VANCOUVER, British Columbia, March 13, 2019 /PRNewswire/ -- Sophiris Bio Inc. (NASDAQ: SPHS) (the "Company," "We" or "Sophiris"), a biopharmaceutical company developing topsalysin (PRX302), a first-in-class, pore-forming protein, in late-stage clinical trials for the treatment of patients with urological diseases, today reported financial results for the fourth quarter and full year 2018 and recent corporate highlights.
"During the past year, Sophiris has made important progress in determining the ideal method for topsalysin administration as a focal treatment for localized prostate cancer," said Randall E. Woods, president and CEO of Sophiris. "The Phase 2b study provided a compelling look at this potential, showing that a single administration of topsalysin led to a clinical response in 27% of patients, including a complete ablation of tumor in 16% of patients. Our investigators have also noted that a drug capable of delaying or obviating the need for radical therapy in nearly a third of the patient population with the potential safety profile that we have seen to date could be very attractive for patients with localized intermediate risk prostate cancer."
Allison Hulme, Ph.D., chief operating officer and head of R&D for Sophiris, added: "In recent weeks we have made significant progress on a key next step for the development of topsalysin: the development of a Phase 3 protocol for localized prostate cancer. Based on both the efficacy and the encouraging safety data from our Phase 2 program and the invaluable input from our Scientific Advisory Board who are supportive of our continuing development of topsalysin as a focal therapy, we have finalized a proposed Phase 3 design and initiated the process of obtaining formal scientific advice from the European Medicines Agency (EMA). We are on track to obtain feedback from the EMA in the first half of this year."
Woods added, "In addition to working with regulatory authorities to determine the potential path to market, we have been actively pursuing options to move topsalysin into the final stages of clinical development, and we currently believe that the ideal funding option will either be a potential development partnership or other strategic transaction. We have also re-prioritized some development activities enabling us to extend our cash runway through the third quarter of this year."
Recent Corporate Highlights:
- Completion of Phase 2b trial in localized prostate cancer. In December, we provided top-line data from patients who received a second administration of topsalysin in the trial. Eleven of the 37 patients evaluated six months after receiving a single administration of topsalysin went on to receive a second administration. It was determined that both the first and the second administration of topsalysin continue to appear safe and well-tolerated by patients. There were no adverse events considered related to topsalysin that were experienced by more than one patient following the second administration. Importantly, a total of 27% of patients (10/37) demonstrated a clinical response six months following the first administration of topsalysin. Six of the ten clinical responders experienced a complete ablation of their tumor with no remaining tumor detected following a targeted biopsy of the treated area.
- Preparations for Phase 3 trial in localized prostate cancer. We, along with our Scientific Advisory Board and our other scientific advisors, believe that the data generated in the single-administration portion of the Phase 2b prostate cancer study supports the advancement of the program into a single Phase 3 pivotal trial. Currently, we have initiated formal scientific advice with EMA and in the coming weeks plan to initiate dialog with the U.S. Food and Drug Administration on the single confirmatory Phase 3 design.
- Completion of topsalysin drug substance manufacturing. We recently completed the manufacture of a batch of topsalysin drug substance, which is planned for use in the upcoming Phase 3 confirmatory study in localized prostate cancer.
- Funding of future development of topsalysin. The management team remains focused on determining the best path forward for funding future clinical development for topsalysin and continues to engage in strategic discussions as part of this effort.
At December 31, 2018, the Company had cash, cash equivalents and securities available-for-sale of $12.5 million and working capital of $8.2 million. The Company expects that its existing cash and cash equivalents will be sufficient to fund its operations through September 2019, assuming no new clinical trials are initiated and the Company continues operating as a going concern. The Company will require significant additional funding to advance topsalysin in clinical development. As of December 31, 2018, the outstanding principal balance of the Company's term loan was $7 million on which the Company is currently making monthly interest only payments and is scheduled to begin making principal payments in April 2019.
For the three months ended December 31, 2018
The Company reported a net income of $5.5 million or $0.18 per share for the three months ended December 31, 2018, compared to net loss of $4.0 million or ($0.13) per share for the three months ended December 31, 2017. The net income for the three months ended December 31, 2018 was driven by a non-cash gain related to the revaluation of the Company's warrant liability.
Research and development expenses
Research and development expenses were $2.0 million for the three months ended December 31, 2018, compared to $1.9 million for the three months ended December 31, 2017. The increase in research and development costs was primarily attributable to increases in the costs associated with manufacturing activities for topsalysin offset in part by a decrease in personnel related costs.
General and administrative expenses
General and administrative expenses were $0.9 million for the three months ended December 31, 2018, compared to $1.3 million for the three months ended December 31, 2017. The decrease in general and administrative expense was primarily due to decreases in personnel related expenses and marketing research activities.
Gain (loss) on revaluation of the warrant liability
Gain on revaluation of the warrant liability was $8.5 million for the three months ended December 31, 2018, compared to a loss on the revaluation of the warrant liability of $0.6 million for the three months ended December 31, 2017. The Company's outstanding warrants may require it to pay the warrant holder cash under certain provisions of the warrant therefore the Company accounts for these warrants as a liability, and the Company is required to calculate the fair value of these warrants each reporting date. The non-cash gain reported for the three months ended December 31, 2018, was associated with a decrease in the fair value of the Company's warrant liability from September 30, 2018 to December 31, 2018, which is calculated using a Black-Scholes pricing model. The decrease in the fair market value of the Company's warrant liability was directly related to a decrease in the Company's stock price from September 30, 2018 to December 31, 2018. Certain inputs utilized in the Company's Black-Scholes fair value calculation may fluctuate in future periods based upon factors which are outside of the Company's control. A significant change in one or more of these inputs used in the calculation of the fair value may cause a significant change to the fair value of the Company's warrant liability, which could also result in a material non-cash gain or loss being reported in the Company's consolidated statement of operations and comprehensive loss.
For the year ended December 31, 2018
The Company reported a net loss of $6.8 million or ($0.23) per share for the year ended December 31, 2018 compared to a net loss of $8.6 million or ($0.29) per share for the year ended December 31, 2017.
Research and development expenses
Research and development expenses were $10.7 million for the year ended December 31, 2018 compared to $6.2 million for the year ended December 31, 2017. The increase in research and development costs was primarily attributable to increases in the costs associated with manufacturing activities for topsalysin.
General and administrative expenses
General and administrative expenses were $4.4 million for the year ended December 31, 2018 compared to $5.7 million for the year ended December 31, 2017. The decrease in general and administrative expense was primarily due to decreases in non-cash stock-based compensation expense, marketing research activities and its personnel related costs.
Gain on revaluation of the warrant liability
Gain on revaluation of the warrant liability was $8.7 million for the year ended December 31, 2018 as compared to a gain of $3.3 million for the year ended December 31, 2017. The non-cash gain is associated with the change in the fair value of our warrant liability which was calculated using a Black-Scholes pricing model.
