“2017 was a transformative year for Arsanis, with significant clinical, financial and staffing achievements that position us well as we advance our novel monoclonal antibody-based therapies to address serious infections,” said René Russo, chief executive officer of Arsanis. “We are pleased with the continued progress of our Phase 2 clinical study of ASN100, which we believe represents a novel approach to managing the clinical and health economic burden of pneumonia in critically ill hospital patients. We expect to report results of an interim analysis from this study in the first half of this year and top-line efficacy results from the completion of this trial in the second half of 2018.”
ASN100, Arsanis’ lead product candidate, is a first-in-class mAb therapy that neutralizes the six cytotoxins critical to Staphylococcus aureus pneumonia pathogenesis, and is currently being evaluated in a Phase 2 clinical trial for the prevention of S. aureus pneumonia in high-risk, mechanically ventilated patients. Arsanis believes ASN100 has both preventive and therapeutic potential in this setting and may reduce the need for multiple antibiotic courses that contribute to antibiotic resistance, toxicity, and subsequent infections. The company believes infection prevention in this population would also reduce mechanical ventilation days, shorten hospital stays, reduce healthcare costs, and decrease the risk of re-hospitalization.
Dr. Russo continued, “We also are making progress in other areas, including the advancement of our ASN500 program, which currently focuses on evaluating multiple highly potent monoclonal antibodies that target respiratory syncytial virus, or RSV. We expect to select a lead mAb for development from this program in the near term and to begin preclinical testing to advance this candidate toward clinical development.”
“Our completion of an initial public offering and concurrent private placement of common stock in November 2017 combined with our April 2017 Series D financing provide us with adequate capital to fund our planned operations into the second half of 2019, well beyond our anticipated timelines for the Phase 2 data from our lead ASN100 program,” said Michael Gray, chief operating and chief financial officer of Arsanis. “Our ASN500 program is currently funded under a grant agreement with the Bill & Melinda Gates Foundation, and we therefore expect that the majority of our available capital will continue to be directed toward advancement of ASN100.”
Key 2017 highlights
- Advanced the Phase 2 clinical trial of ASN100 to evaluate the safety, tolerability, and efficacy of a single dose of ASN100 versus placebo for the prevention of Staphylococcus aureus pneumonia in high-risk, mechanically ventilated patients.
- Secured an exclusive worldwide license to antibodies targeting RSV from Adimab and entered into a grant agreement of up to $9.3 million from the Bill & Melinda Gates Foundation to fund preclinical development activities.
- Closed on a $50.5 million Series D financing led by the Bill & Melinda Gates Foundation, with strong support from existing investors.
- Presented preclinical and Phase 1 clinical data supportive of ASN100’s non-antibiotic mechanism of action, safety and pharmacokinetics.
- Appointed senior pharmaceutical executives Chip Clark and David McGirr to our Board of Directors and promoted Michael Gray to Chief Operating Officer and Chief Financial Officer.
- Closed the company’s initial public offering of 4,600,000 shares and a concurrent private placement of 2,000,000 shares of its common stock at a public offering price of $10.00 per share, including 600,000 additional shares of common stock issued upon the exercise in full by the underwriters of their over-allotment option. The gross proceeds to Arsanis from these two offerings were $66.0 million, before deducting underwriting discounts and commissions and other offering expenses.
Arsanis expects that it will make presentations at the following conferences through April 2018:
- Presentation at the 38th Annual Cowen and Company Health Care Conference on March 12, 2018 in Boston, MA
- Presentation at the Needham & Company 17th Annual Healthcare Conference on March 27, 2018 in New York City
- Multiple presentations at the 28thEuropean Congress of Clinical Microbiology and Infectious Diseases from April 21-24, 2018, in Madrid, Spain
Fourth Quarter 2017 Financial Results
For the fourth quarter ended December 31, 2017, Arsanis reported a net loss of $11.2 million, or $1.68 loss per share, as compared to a net loss of $5.3 million and $10.37 loss per share for the fourth quarter of 2016.
Operating expenses for the fourth quarter of 2017 were $11.6 million, as compared to $5.7 million for the fourth quarter of 2016, and were comprised of the following:
Research and development expenses were $9.2 million for the fourth quarter of 2017, as compared to $4.2 million for the fourth quarter of 2016. The increase of $5.0 million was primarily due to an increase of $4.2 million in direct costs for our ASN100 program, an increase of $0.3 million in direct costs for our ASN500 program, and an increase of $0.6 million in unallocated research and development expenses.
General and administrative expenses were $2.4 million for the fourth quarter of 2017, as compared to $1.5 million for the fourth quarter of 2016. The increase of $0.9 million was primarily due to an increase of $0.2 million in personnel-related costs and an increase of $0.6 million in professional fees.
