ZymoGenetics Reports First Quarter 2007 Financial Results PR Newswire -- May 2, 2007 Continuing progress in clinical trials and commercialization preparedness SEATTLE, May 2 /PRNewswire-FirstCall/ -- ZymoGenetics, Inc. (Nasdaq: ZGEN) today reported its financial results for the first quarter ended March 31, 2007. The company reported a net loss for the quarter of $33.3 million, or $0.49 per share, reflecting continuing investment in the development of product candidates and preparation for launch of recombinant human Thrombin (rhThrombin). For the first quarter of 2006, ZymoGenetics had a net loss of $31.7 million, or $0.48 per share. The company ended the quarter in a strong financial position, with $224.0 million of cash and investments. "We were very pleased in the first quarter to report good news from the FDA regarding the regulatory pathway for spray rhThrombin," stated Bruce L.A. Carter, President and CEO. "Our preparations for commercialization of recombinant human thrombin in the U.S. are on schedule, and we continue to expect to work with a partner outside the U.S. Also, we're on track for another year of significant progress in our other research and development programs. As we work to develop innovative drugs, we're mindful of and motivated by the many patients who suffer from lupus, cancer and other serious diseases and who are in great need for new treatments," added Dr. Carter. Revenues for the quarter decreased to $5.2 million, compared to $7.4 million for the same period in the prior year. The decrease resulted primarily from reduced option fee revenues. In the fourth quarter of 2006, the company's option and license agreement with Novo Nordisk A/S expired. This agreement provided $1.9 million of revenue in the first quarter of 2006. Research and development expenses for the quarter decreased by 10% to $29.8 million, compared to $33.0 million for the first quarter of 2006. The decrease was partially attributable to a reduction in costs associated with the manufacture of rhThrombin. The company continues to expect to incur significant rhThrombin manufacturing costs in 2007, with most deliveries occurring in the last nine months of the year. Until FDA approval, these manufacturing costs will be expensed to research and development. Reduced clinical trial costs also contributed to the expense decrease, particularly resulting from the completion of the rhThrombin Phase 3 clinical trial in mid 2006. General and administrative expenses increased as expected by 24% to $9.7 million for the quarter, compared to $7.8 million for the first quarter of 2006. Most of the increase in the first quarter of 2007 was attributable to increased hiring of employees needed to prepare for the planned launch of rhThrombin in late 2007. Higher legal and market research costs also contributed to the increase. Development Programs The company continued advancement of its clinical programs during the first quarter of 2007. Following are updates on each program: rhThrombin: During recent weeks, ZymoGenetics completed hiring and training a team of medical science liaisons. This team will serve as an educational resource for physicians and will build relationships with key opinion leaders. A manuscript describing the company's rhThrombin Phase 3 trial will be published in a peer- reviewed medical journal in the next few months. During the quarter, the company received notification of the acceptance of its Biologic Licensing Application by the FDA, with an anticipated response (PDUFA) date of October 18, 2007. Accordingly, the company is building inventory for an anticipated product launch in Q4 2007, and is making final preparations for pre-approval inspections by the FDA, which are expected to occur within the next few months. ZymoGenetics was also informed by the FDA that no further clinical trials will be necessary to support a marketing application for recombinant thrombin co-packaged with a spray device. As a result, it is now anticipated that the launch of rhThrombin delivered co-packaged with a spray device will occur in early 2008, much sooner than originally projected. Atacicept: ZymoGenetics and Merck Serono are enrolling patients in a Phase 2 trial studying the efficacy of atacicept with rheumatoid arthritis patients whose disease has not responded adequately to TNF inhibitors. European sites began opening in March to help enroll approximately 300 patients in this trial. Results from the open-label atacicept B-CLL trial will be presented at the ASCO annual meeting held in early June. The companies are also working toward beginning enrollment in Phase 2/3 trials suitable for registration with SLE patients in the second half of 2007. Ongoing discussions with the FDA and the European Medicines Agency are aimed toward finalizing protocols for these trials within the next few months. Interleukin 21 (IL-21): ZymoGenetics has completed enrollment in the dose escalation portion of its Phase 1 trial combining IL-21 with rituximab (a product of Genentech, Inc. and Biogen IDEC) for the treatment of lymphoma patients. The second part of this trial will begin enrollment shortly, with planned completion by the end of this year. The company is also enrolling patients in the Phase 1 part of its Phase 1/2 renal cell carcinoma trial combining IL-21 with sorafenib (a product of Bayer Healthcare AG and Onyx Pharmaceuticals, Inc.). In collaboration with Novo Nordisk, enrollment is continuing in a Phase 2 study of IL-21 as a monotherapy for patients with metastatic melanoma. PEG-interferon lambda: ZymoGenetics is currently enrolling healthy volunteers in a Phase 1a trial of this potential Hepatitis C therapy. This dose escalation study is examining the safety, pharmacokinetics and pharmacodynamics following single subcutaneous dosing. The company anticipates that results from this trial will be available in the second half of 2007.
