SAN DIEGO, Aug. 8, 2016 /PRNewswire/ -- Pfenex Inc.

Pfenex disclosed today in a separate press release that the company will be regaining the full rights to PF582, a biosimilar candidate to Lucentis (ranibizumab), based on our collaboration partner's strategic review of the current therapeutic focus of its biosimilar pipeline.  In addition, today Pfenex disclosed the Phase 1/2 PF582 data in the separate press release.

Pfenex also announced today the positive interim data from our anthrax vaccine Phase 1a study, which may be referred to in the separate press release issued today.

"We believe that PF582 has significant value as highlighted by the Phase 1/2 data we released this morning.  As the program transitions back to Pfenex, we will be moving ahead with strategic options for PF582. Our diverse pipeline continues to advance as demonstrated by the positive anthrax vaccine update today.  Additionally, the announcement of the Jazz collaboration on July 28th underscores the value of the Pfenex Expression Technology platform and our development capability," stated Bertrand C. Liang, chief executive officer of Pfenex.  "As part of the Jazz collaboration, we have the opportunity to efficiently develop a portfolio of hematology programs.  Given this productive collaboration and our recent pipeline review, we have decided to advance the assets that are part of the Jazz collaboration ahead of the PF530 biosimilar Betaseron opportunity and reduce the expenses associated with PF530.  The PF530 program is at an important inflection point, having accessed an abbreviated biosimilar development path in the United States, consisting of a pivotal PK/PD study in healthy subjects and an immunogenicity study in multiple sclerosis patients.  However, by focusing on pipeline programs that balance value creation with development costs, we will continue to improve our capital efficiency. Potential strategic opportunities for the PF530 program will be explored, given the successful advancement of PF530 and the positive regulatory feedback. This re-alignment underscores our disciplined approach to capital allocation. Over the remainder of 2016, we are looking forward to key data readouts and study initiations which we believe will further highlight our differentiated business strategy and capabilities."

Business Review and Update

Pfenex initiated the Phase 1 trial for its recombinant anthrax vaccine in 2015 and today reported positive interim data from the study in a separate press release.  In August 2015, Pfenex announced signing a five year, cost plus fixed fee contract valued at up to $143.5 million with the Biomedical Advanced Research and Development Authority (BARDA) of the Department of Health and Human Services (HHS), for the advanced development of our mutant recombinant protective antigen anthrax vaccine, which offers the potential for a dramatic improvement in the rapid production of large amounts of high value stable recombinant anthrax vaccine for the U.S. Government.

Pfenex has regained full rights to PF582 and announced in a separate release today the results of the phase 1/2 trial.  Pfenex enrolled a total of 25 VEGF-inhibitor naïve patients with neovascular age-related macular degeneration (AMD) in the PF582 Phase 1/2 trial (13 received PF582, including 1 sentinel patient who received open label PF582, 12 received Lucentis).  All patients received 3 monthly intravitreal injections. The primary endpoint of the study was safety and tolerability of PF582 compared to that of Lucentis in patients with neovascular AMD.  With respect to safety, there were no meaningful differences in intra-ocular pressure between PF582 and Lucentis at any of the timepoints. Additionally, there were no imbalances in local or systemic adverse events.  The immunogenicity results showed comparable anti-drug antibody findings between PF582 and Lucentis throughout the 3 month study period. The efficacy and pharmacodynamic results indicated that there were no meaningful differences in best corrected visual acuity and the decreases in central retinal thickness between PF582 and Lucentis at any of the timepoints were also similar. 

The Pfenex collaboration with Jazz Pharmaceuticals on multiple early stage hematology product candidates also includes an option for Jazz Pharmaceuticals to negotiate a license for a recombinant pegaspargase product candidate with Pfenex.  Pfenex received upfront and option payments totaling $15 million and may be eligible to receive additional payments of up to $166 million based on the achievement of certain development-, regulatory-, and sales-related milestones, including up to $41 million for certain non-sales-related milestones.  Pfenex may also be eligible to receive tiered royalties on worldwide sales of any products resulting from the collaboration. Both parties will be contributing to development efforts.

We anticipate initiating the PF708 clinical program by year end to satisfy the regulatory filing requirements.  PF708 is our peptide product candidate that we are developing as a therapeutic equivalent to Forteo (teriparatide) through the 505(b)(2) regulatory development pathway.  The PF708 clinical program is expected to include an immunogenicity/pharmacokinetic study in subjects with osteoporosis.     

Process development for PF529, our biosimilar candidate to Neulasta (pegfilgrastim), is ongoing and we anticipate receiving regulatory feedback by the end of 2016.

Given the Jazz collaboration and our recent pipeline review, Pfenex has decided to advance the hematology assets that are part of the Jazz collaboration ahead of the PF530 biosimilar Betaseron opportunity.  The expenses associated with PF530 will be reduced as part of the portfolio re-alignment.  Pfenex completed a Phase 1 trial of PF530, a biosimilar candidate to Betaseron, in 2015 which enrolled 12 healthy subjects.  Based on the analysis of the trial PK and PD parameters, no meaningful differences between PF530 compared to the reference compound were observed.  Potential strategic opportunities for the PF530 program will be explored, given the successful advancement of PF530 and the positive regulatory feedback.

Financial Highlights for the Second Quarter

Total Revenue increased by $0.8 million, or 37%, to $3.1 million in the three month period ended June 30, 2016 compared to $2.3 million in same period in 2015. The increase in revenue was due to the stage of development of our anthrax vaccine product candidates under our government contracts, offset by a decrease in product sales. Given the nature of the novel vaccine development process, revenue will fluctuate depending on stage of development.

Cost of revenue of $1.4 million increased by approximately $0.5 million in the three month period ended June 30, 2016 compared to $0.9 million in the same period in 2015. The increase in cost of revenue was due primarily to an increase in costs for our anthrax vaccine product candidates under our government contracts. The increase was offset by a decrease in product sales, which is impacted by our customers' product development and clinical progression.  Given the nature of the novel vaccine development process, these costs will fluctuate depending on stage of development.

Research and development expenses increased by approximately $4.0 million to $7.6 million in the three month period ended June 30, 2016 compared to $3.6 million in same period in 2015. The increase in research and development expense was due to the increase in development activity of our product candidates PF708 and PF530 and the hiring of additional personnel dedicated to our research and development efforts. We expect research and development expenses to increase for the foreseeable future as we advance our lead candidates and pipeline product candidates.

Selling, general and administrative expenses increased by $0.6 million, or 17%, to $4.3 million in the three month period ended June 30, 2016 compared to $3.7 million in the same period in 2015. The increase in selling, general and administrative expenses during the periods presented were primarily due to an increase in headcount, as well as increases in salaries and other personnel costs. We expect general and administrative costs to continue to increase for activities associated with operating as a publicly-traded company.

Cash and cash equivalents as of June 30, 2016 was $89.6 million.
