Media/Investors contact: Jonathan Fassberg The Trout Group (212) 477-9077 x16 CYTOGEN REPORTS SECOND QUARTER 2005 FINANCIAL RESULTS R&D Day Scheduled for September 13, 2005 in New York PRINCETON, N.J., (August 4, 2005) -- Cytogen Corporation (Nasdaq: CYTO), a product-driven biopharmaceutical company, today reported its consolidated financial results for the second quarter and six months ended June 30, 2005. FINANCIAL HIGHLIGHTS - -------------------- o Sales of QUADRAMET(R) (samarium Sm-153 lexidronam injection) were $2.2 million for the second quarter ended June 30, 2005 compared to $1.6 million for the same quarter of 2004, representing 33% revenue growth year-over-year. For the six months ended June 30, 2005, sales of QUADRAMET were $4.2 million compared to $3.5 million in the same period of 2004, representing 21% revenue growth year-over-year. o Sales of PROSTASCINT(R) (capromab pendetide) kits were $1.9 million for the second quarter ended June 30, 2005 compared to $2.3 million for the same quarter in 2004. For the six months ended June 30, 2005, sales of PROSTASCINT were $3.8 million compared to $4.0 million in the same period of 2004. The decrease from the prior year periods is primarily due to changes in distributor buying patterns evidenced in the second quarter of 2004. o Total product revenues for the second quarter of 2005 were $4.1 million compared to $3.9 million in the second quarter of 2004. For the six months ended June 30, 2005, total product revenues were $8.0 million compared to $7.5 million in the same period of 2004. o Average gross margin for the six months ended June 30, 2005 improved to 43% compared to 37% for the same period in 2004. o Cytogen reported a net loss of $7.7 million, or $0.50 per basic and diluted share in the second quarter of 2005, compared to $4.4 million, or $0.30 per basic and diluted share, for the same period in 2004. For the six months ended June 30, 2005, total net loss was $14.3 million, or $0.92 per basic and diluted share, compared to $8.7 million, or $0.63 per basic and diluted share, in the same period of 2004. The increase in net loss results primarily from the implementation of new marketing initiatives and expansion of the Company's sales force, which was substantially completed in January 2005. "The expansion of our sales force and marketing programs during the first half of 2005 and our efforts to extend our product lines through targeted clinical development initiatives will be important contributors to our future success," said Michael D. Becker, Cytogen's president and chief executive officer. "We have hired great people throughout the ranks and our customers are giving us positive feedback on our products and pipeline. As a commercial organization, I believe we are better positioned today than ever and are excited by our prospects for growth in the second half of 2005 and beyond." PRODUCT REVENUE - --------------- QUADRAMET QUADRAMET is Cytogen's flagship product for the relief of pain due to metastatic bone disease arising from prostate, breast, multiple myeloma and other types of cancer. Sales of QUADRAMET were $2.2 million for the quarter ended June 30, 2005 compared to $1.6 million for the same period in 2004, representing 33% revenue growth year-over-year. For the six months ended June 30, 2005, sales of QUADRAMET were $4.2 million compared to $3.5 million in the same period of 2004, representing 21% revenue growth year-over-year. QUADRAMET QUARTERLY REVENUE SUMMARY ($'s in millions) 2004 2004 2004 2004 | 2005 2005 Q1 Q2 Q3 Q4 | Q1 Q2 ---- ---- ---- ---- ---- ---- Product Sales $1.9 $1.6 $1.9 $1.9 | $2.1 $2.2 PROSTASCINT Sales of PROSTASCINT kits (for the preparation of Indium In-111 capromab pendetide), the first and only commercial monoclonal antibody-based agent that targets prostate-specific membrane antigen (PSMA) to image the extent and spread of prostate cancer, were $1.9 million for the quarter ended June 30, 2005 compared to $2.3 million in the same period of 2004. For the six months ended June 30, 2005, sales of PROSTASCINT were $3.8 million compared to $4.0 million in the same period of 2004. The decrease from the prior year periods is primarily due to changes in distributor buying patterns evidenced in the second quarter of 2004. PROSTASCINT QUARTERLY REVENUE SUMMARY ($'s in millions) 2004 2004 2004 2004 | 2005 2005 Q1 Q2 Q3 Q4 | Q1 Q2 ---- ---- ---- ---- ---- ---- Product Sales $1.7 $2.3 $1.3 $1.8 | $1.9 $1.9 "Our strategy for increasing product sales is centered on key drivers of long-term growth for both QUADRAMET and PROSTASCINT," said Thomas Lytle, Cytogen's senior vice president of sales and marketing. "For QUADRAMET, these include: (i) distinguishing the physical properties of QUADRAMET from first-generation agents within its class, (ii) empowering and marketing to key prescribing audiences, (iii) broadening palliative use within label beyond prostate cancer to include breast, lung, multiple myeloma, (iv) evaluating the role of QUADRAMET in combination with other commonly used oncology agents, and (v) expanding clinical development to demonstrate the potential tumoricidal versus palliative attributes of QUADRAMET. For PROSTASCINT, these drivers include: (i) improving image quality through fusion technology, (ii) validating the antigen targeted by PROSTASCINT as an independent prognostic factor, (iii) the publication and presentation of outcomes data, (iv) development of image-guided applications including brachytherapy, intensity modulated radiation therapy, surgery, and cryotherapy, and (v) expanding clinical development to demonstrate the potential for PROSTASCINT to both monitor response to cytotoxic therapies and image PSMA expression in other cancers. We believe we now have the resources, talent and unique opportunity to maximize the potential of these two important products." COSTS AND EXPENSES - ------------------ TOTAL OPERATING EXPENSES Total operating expenses for the quarter ended June 30, 2005 were $12.0 million compared to $8.4 million for the same period in 2004. For the six months ended June 30, 2005, total operating expenses were $22.7 million compared to $16.3 million in the same period of 2004. COST OF PRODUCT REVENUE Cost of product revenue for the second quarters ended June 30, 2005 and June 30, 2004 were $2.3 million and $2.4 million, respectively. For the six months ended June 30, 2005, cost of product revenue was $4.7 million compared to $4.8 million in the same period of 2004, and primarily reflects QUADRAMET and PROSTASCINT manufacturing costs, royalties paid by Cytogen on the Company's product sales, and the amortization of the up-front payment to Berlex to reacquire the marketing rights to QUADRAMET. SG&A EXPENSES Selling, general and administrative expenses for the quarter ended June 30, 2005 were $6.7 million compared to $4.9 million for the same period in 2004. For the six months ended June 30, 2005, total selling, general and administrative expenses were $13.7 million compared to $8.8 million in the same period of 2004. The increase in selling, general and administrative expenses is primarily driven by expanded investment for the commercial support of both QUADRAMET and PROSTASCINT, including the implementation of new marketing initiatives and expansion of the Company's sales force, which was substantially completed in January 2005. R&D EXPENSES Research and development expenses for the quarter ended June 30, 2005 were $1.4 million compared to $541,000 for the same period in 2004. For the six months ended June 30, 2005, total internal research and development expenses were $2.1 million compared to $1.3 million in the same period of 2004. The increase in research and development expenses is primarily driven by new clinical development initiatives for both QUADRAMET and PROSTASCINT and a $500,000 charge in the second quarter of 2005 for a non-cash milestone payment related to the progress of PSMA development programs. In addition, research and development expenses include preclinical development costs associated with the Company's recently announced program to attach the therapeutic radionuclide lutetium-177 as a payload to the 7E11.C5.3 monoclonal antibody utilized in PROSTASCINT. EQUITY IN LOSS OF JOINT VENTURE Joint venture research and development expenses reflect costs associated with the PSMA Development Company LLC ("PDC"), a joint venture between Cytogen and Progenics Pharmaceuticals, Inc., for the development of in vivo immunotherapies targeting PSMA. Cytogen's share of the equity in the loss of PDC for the second quarter and six months ended June 30, 2005 were $1.7 million and $2.2 million, respectively, compared to $542,000 and $1.4 million, respectively, in the comparable periods in 2004. The increase over prior year periods is primarily due to Cytogen's share of the $2.0 million upfront fee incurred by PDC to license proprietary antibody-drug conjugate (ADC) technology from Seattle Genetics, Inc. for use with PDC's antibodies targeting PSMA, as previously communicated on June 20, 2005. INVENTORIES Inventories as of June 30, 2005 were $5.1 million compared to $3.6 million as of December 31, 2004. The increase in inventories is due primarily to the current manufacturing runs of PROSTASCINT. In September 2004, Cytogen entered into a manufacturing agreement with Laureate Pharma, L.P. pursuant to which Laureate is manufacturing PROSTASCINT for Cytogen in its Princeton, NJ facility. Cytogen believes that the agreement will provide a sufficient supply of PROSTASCINT to satisfy commercial requirements for approximately the next four years, based upon current sales levels. In addition, Cytogen believes that the agreement will provide sufficient supply of the 7E11.C5.3 monoclonal antibody required for initial clinical development of the Company's therapeutic program. CASH POSITION - ------------- Cytogen's cash, cash equivalents and short-term investments balance as of June 30, 2005 was $20.5 million compared to $35.8 million as of December 31, 2004. This June 30, 2005 balance does not reflect approximately $14.0 million in gross proceeds from the July 2005 sale of common stock and warrants, which closed during the third quarter of 2005. SECOND QUARTER PRODUCT AND PIPELINE HIGHLIGHTS - ---------------------------------------------- QUADRAMET o The publication of new data from a phase II study of QUADRAMET in combination with docetaxel (Taxotere(R), Aventis Pharmaceuticals, a member of the sanofi-aventis Group) for the treatment of patients with hormone refractory prostate cancer. The published abstract is part of the proceedings at the 2005 American Society of Clinical Oncology (ASCO) Annual Meeting and the lead investigator was Anders Widmark, M.D., Ph.D., professor, department of oncology, Umea University, Sweden. o The presentation of a new clinical study evaluating the use of high dose QUADRAMET in conjunction with gemcitabine for the treatment of osteosarcoma. The data was presented during the 2005 ASCO Annual Meeting and the lead investigator was Peter Anderson, M.D., Ph.D., a pediatric oncologist who performed the work at the Mayo Clinic and is now at The University of Texas MD Anderson Cancer Center, another center active in studies using QUADRAMET. o The presentation of data from studies in which patients received multiple doses of QUADRAMET. The data were presented during the 2005 ASCO Annual Meeting and the lead author was Oliver Sartor, M.D., a medical oncologist who is director of the Stanley S. Scott Cancer of Louisiana State University Health Sciences Center in New Orleans. o The presentation of new data demonstrating the use of QUADRAMET alone and in conjunction with chemotherapy for the treatment of prostate, breast, lung, and other cancers. The abstracts were presented during the 2005 Society of Nuclear Medicine (SNM) Annual Meeting and were reported by independent investigators. PROSTASCINT o The presentation of outcome data obtained over a seven-year follow-up period demonstrating that PROSTASCINT imaging both increased disease-free survival rates and independently predicted a three-fold increase in risk of recurrent disease in prostate cancer patients following definitive local therapy. The study was presented during the 26th American Brachytherapy Society (ABS) Annual Meeting and was carried out by investigators from Case Western Reserve University, University Hospital of Cleveland and Aultman Hospital in Canton, Ohio and was led by Rodney Ellis, M.D., radiation oncologist at Aultman Hospital and assistant professor of urology at Case Western Reserve University School of Medicine. PSMA o Cytogen and Dowpharma(SM) contract manufacturing services, a business unit of The Dow Chemical Company, announced a collaboration to create a targeted oncology product designed to treat prostate and other cancers. Under the agreement, Dowpharma's proprietary MeO-DOTA bifunctional chelant technology will be used to radiolabel Cytogen's 7E11.C5.3 monoclonal antibody with the therapeutic radionuclide lutetium-177. Cytogen recently completed the scale up and manufacture of the toxicology lot for this product candidate and preclinical toxicology studies are scheduled to begin during the third quarter of 2005 in advance of filing an investigational new drug (IND) application for the treatment of prostate cancer in the first quarter of 2006. o Seattle Genetics licensed its proprietary antibody-drug conjugate (ADC) technology to PDC. The license provides PDC with rights to utilize the ADC technology to link cell-killing drug payloads to PDC's fully human monoclonal antibodies that target PSMA.
