Third Quarter and Nine Month Year-To-Date Financial Results

Total revenue was $11.1 million for the three months ended September 30, 2015, compared to $6.6 million for the comparable period in 2014, representing an increase of 69%. For the nine months ended September 30, 2015, total

revenue was $33.9 million, an 87% increase as compared to total revenue of $18.1 million for the nine months ended September 30, 2014. See Table 1 attached for further details on revenues.  

Product sales represent sales of our proprietary products and devices or device components to our partners.  Product sales were $8.0 million for the three months ended September 30, 2015, compared to $3.6 million for the comparable period in 2014, and totaled $18.5 million for the nine months ended September 30, 2015 as compared to $8.7 million in the comparable period of 2014.  The increase in product sales for the three and nine months ended September 30, 2015 over the comparable periods of 2014 was primarily driven by the growth of OTREXUP™ and the sale of pre-launch quantities of epinephrine auto injectors to Teva in anticipation of a potential approval next year.  

Development revenue represents amounts earned under arrangements with partners in which we develop new products on their behalf.  Frequently, we receive payments from our partners that are initially deferred and recognized as revenue over a development period or upon completion of defined deliverables.  Development revenue was $2.6 million and $8.0 million for the three and nine months ended September 30, 2015, respectively, compared to $1.7 million and $5.0 million for the comparable periods in 2014.

Licensing revenues represent the amounts recognized from up-front or milestone payments received from partners that are initially deferred and recognized over the life of our agreements.  Licensing revenue was less than $0.1 million for the three months ended September 30, 2015, compared to $0.9 million for the comparable period in 2014. Licensing revenue for the first nine months of 2015 totaled $6.1 million compared to $2.8 million for the first nine months of 2014. The year-to-date increase was driven by the recognition of incremental licensing revenue of $5.0 million in connection with the termination of our agreement with LEO Pharma during the second quarter of 2015.  As a result of the termination of this agreement we did not recognize any licensing revenues in the third quarter 2015.

Royalty revenue is recognized primarily from the in-market sales of products sold by our partners.  Royalty revenue was $0.4 million for the three months ended September 30, 2015, compared to $0.3 million for the comparable period in 2014. Royalty revenue for the first nine months of 2015 totaled $1.2 million compared to $1.6 million for the first nine months of 2014.

Total gross profit increased in the third quarter of 2015 to $6.0 million compared to $4.1 million in the comparable period in 2014, principally due to the growth of OTREXUP™ and sales of epinephrine auto injectors. Total gross profit for the first nine months of 2015 was $20.4 million as compared to $12.3 million in the first nine months of 2014, representing a period over period increase of 66%. The year-to-date increase was driven by the growth in contribution margins from OTREXUP™ and auto injector device sales, and incremental licensing revenue of $5.0 million recognized in connection with the termination of our agreement with LEO Pharma during the second quarter of 2015, which had no associated cost of revenue.

Total operating expenses were $11.8 million in the third quarter of 2015 compared to $11.2 million in the comparable period in 2014. Total operating expenses for the nine months ended September 30, 2015 were $34.3 million as compared to $37.4 million for the comparable period in 2014, a decrease of 8%. The increase in third quarter operating expenses was primarily due to the increased investment in research and development costs, primarily personnel costs and FDA fees. The decrease in nine month year to date operating expenses was driven by higher costs incurred in 2014 associated with the launch of OTREXUP™ and legal costs that were paid in 2014 for litigation that was settled in 2015.

Net loss was approximately $5.7 million and $14.0 million for the third quarter and first nine months of 2015, respectively, as compared to $7.2 million and $25.1 million for the comparable periods in 2014.  

At September 30, 2015, cash and investments totaled approximately $50.9 million compared to approximately $40.0 million at December 31, 2014.
