Nexvet Reports Financial Results for Second Quarter of Fiscal Year 2016

DUBLIN, Ireland – February 16, 2016 – Nexvet Biopharma (Nasdaq: NVET), a veterinary biologics developer, today announced its financial results for the three and six month periods ended December 31, 2015.

Corporate highlights during the quarter:

A key highlight for the period occurred in November, when the Company announced successful results from the pivotal safety and efficacy study of NV-01. The study met its primary endpoint as agreed under protocol concurrence with the Center for Veterinary Medicine (CVM) at the U.S. Food and Drug Administration (FDA). No significant adverse safety signals were observed in the study. The Company was also pleased to report that NV-01 was well tolerated and retained efficacy out to the final three month efficacy assessment with monthly administration. Statistically significant differences over placebo were also achieved for the majority of the study’s secondary endpoints. This study provided Nexvet with a substantial body of efficacy data that it intends to use as the basis for planned submissions for marketing authorizations in both the U.S. and Europe

“The successful outcome of NV-01’s pivotal safety and efficacy study is a major milestone, providing strong clinical validation of our proprietary platform, PETization, as well as the anti-NGF approach to treating pain associated with osteoarthritis in companion animals. We were particularly pleased to receive compelling clinical data supporting the long duration of efficacy following a monthly injection, a key advantage for monoclonal antibody therapies over small molecules,” commented Dr. Mark Heffernan, Nexvet’s Chief Executive Officer.

During the quarter, Nexvet also announced the initiation of a pilot field study for its product candidate NV-02, an anti-NGF mAb for the control of pain associated with osteoarthritis in cats. This announcement followed positive results from a proof-of-concept efficacy study and a pilot safety study, both announced in June 2015.

In November, the Company was pleased to host its inaugural Animal Health Symposium, which was held in New York City. In addition to discussing NV-01’s positive pivotal study results, an integral part of the event was a key opinion leader forum, which provided investors and analysts with an in-depth educational experience on unmet needs in companion animal health.

Company also provided further insight into all of its 15 active programs in areas where the Company believes biologics could significantly improve treatment paradigms, such as pain, allergy, inflammation and immuno-oncology. The Company is excited about its pipeline as various candidates are scheduled to complete proof-of-concept studies in 2016.

Validation of PETization continued during the quarter with completion of proof-of-concept studies for NV-03. NV-03 is a ‘100% horse’ anti-NGF mAb candidate for the management of chronic pain. This represents the third species (dog, cat, horse) in which Nexvet has now completed positive proof-of-concept studies of its PETized anti-NGF mAbs.

Second Quarter 2015 Financial Results

As of December 31, 2015, Nexvet had cash of $43.1 million.

For the three months ended December 31, 2015, Nexvet reported a net loss of $5.7 million, compared to $2.4 million for the three months ended December 31, 2014. Net loss per share attributable to ordinary shareholders (basic and diluted) for the three months ended December 31, 2015 was $0.49, compared to $2.01 for the three months ended December 31, 2014.

The net loss of $5.7 million for the three months ended December 31, 2015 included operating expenses of $5.6 million, reflecting $3.8 million in research and development expenses and $1.8 million in general and administrative expenses. Other expense of $0.1 million comprised an exchange loss of $0.6 million offset by research and development incentive income of $0.5 million.

The net loss of $2.4 million for the three months ended December 31, 2014 included operating expenses of $4.6 million, reflecting $2.2 million in research and development expenses and $2.4 million in general and administrative expenses. Other income comprised $2.3 million, principally research and development incentive income of $0.9 million and an exchange gain of $1.3 million.

For the six months ended December 31, 2015, Nexvet reported a net loss of $9.7 million, compared to $4.7 million for the six months ended December 31, 2014. Net loss per share attributable to ordinary shareholders (basic and diluted) for the six months ended December 31, 2015 was $0.84, compared to $4.14 for the six months ended December 31, 2014.

The net loss of $9.7 million for the six months ended December 31, 2015 included operating expenses of $11.2 million, reflecting $7.5 million in research and development expenses and $3.7 million in general and administrative expenses. Other income comprised $1.5 million, principally research and development incentive income of $1.0 million and an exchange gain of $0.4 million.

The net loss of $4.7 million for the six months ended December 31, 2014 included operating expenses of $10.0 million, reflecting $4.7 million in research and development expenses and $5.3 million in general and administrative expenses. Other income comprised $5.3 million, principally research and development incentive income of $1.7 million, an exchange gain of $3.3 million and government grant income of $0.3 million.

The increased operating expenses for both the three and six month periods ended December 31, 2015, compared to the corresponding periods in 2014, primarily reflect research and development costs associated with building our team and conducting field studies of our lead programs, offset by a reduction in general and administrative costs primarily due to incurring costs in 2014 associated with preparation for our initial public offering and Irish reorganization.
