Mapatumumab

ROCKVILLE, Md., Aug. 1 /PRNewswire-FirstCall/ -- Human Genome Sciences, Inc., today announced financial results for the quarter ended June 30, 2007. (Logo: ) "In the second quarter, we reported the positive final results of our Phase 2b clinical trial of Albuferon(R) in patients with chronic hepatitis C, and we initiated the second of two pivotal Phase 3 trials of LymphoStat-B(R) in patients with lupus," said H. Thomas Watkins, President and Chief Executive Officer. "All four of the Phase 3 trials planned for Albuferon and LymphoStat-B are now underway. We expect to complete enrollment in both of the Albuferon Phase 3 trials in 2007. Clinical results continue to emerge suggesting that each of these products has blockbuster potential if Phase 3 trials are successful. Our cash position is strong, and we are making steady progress toward commercialization." HGS reported that net cash burn for the six months ended June 30, 2007 amounted to $54 million, net of a $47.5 million milestone payment received from Novartis in the first quarter of the year. The Company continues to expect that net cash burn will amount to $145-165 million for the full year 2007. "We substantially reduced our net loss for the second quarter and first half of 2007, compared with the same periods a year ago," said Tim Barabe, Senior Vice President and Chief Financial Officer. "We controlled our net cash burn in the first half through a combination of increased revenues, clinical development cost-sharing and spending controls, and we continue on track to end 2007 with net cash burn of $145-165 million." SECOND QUARTER 2007 FINANCIAL RESULTS HGS reported increased revenues for the quarter ended June 30, 2007 of $9.0 million, compared with revenues of $2.2 million for the same period in 2006. This included $5.7 million in revenue recognized from the Albuferon agreement with Novartis, and $1.6 million in revenue recognized from the LymphoStat-B agreement with GlaxoSmithKline (GSK). The Company reported a reduced net loss of $51.3 million ($0.38 per share) for the quarter ended June 30, 2007, compared with a net loss for the second quarter of 2006 of $61.3 million ($0.47 per share). As of June 30, 2007, cash and investments totaled $704.4 million, of which $634.3 million is unrestricted and available for operations. This compares with cash and investments totaling $763.1 million, of which $701.9 million was unrestricted and available for operations, as of December 31, 2006. HGS reported increased revenues of $18.3 million for the first six months of 2007, compared to revenues of $9.1 million for the same period of the previous year. Revenues for the six months of 2007 included $11.4 million in revenue recognized from the Albuferon agreement with Novartis and $3.2 million in revenue recognized from the LymphoStat-B agreement with GSK. The Company reported a reduced net loss of $102.3 million ($0.76 per share) for the six months ended June 30, 2007, compared with a net loss of $123.4 million ($0.94 per share) for the same period of the previous year. HIGHLIGHTS OF RECENT PROGRESS Albuferon: Positive Final Results of Phase 2b Trial In June 2007, HGS announced the final results of a Phase 2b trial of Albuferon (albinterferon alfa-2b) in combination with ribavirin in patients with chronic hepatitis C. Albuferon requires half as many injections as Pegasys (peginterferon alfa-2a), the current market leader, and results to date suggest that Albuferon may offer efficacy at least comparable to Pegasys, with the potential for less impairment of quality of life and daily activity during treatment. The Company expects that the Phase 2b study results will be presented in full at a scientific meeting later in 2007. HGS expects to complete the enrollment of patients in two pivotal Phase 3 clinical trials of Albuferon before the end of 2007. These trials, assuming they are successful, will provide the data to support filing of global marketing applications for Albuferon in 2009. Albuferon is being developed by HGS and Novartis under an exclusive worldwide development and commercialization agreement entered into in June 2006. LymphoStat-B: Positive Phase 2 Data; Second Phase 3 Trial Initiated In June 2007, at the annual congress of the European League Against Rheumatism (EULAR), clinical investigators presented Phase 2 results demonstrating that LymphoStat-B (belimumab) produced significant improvements in disease activity in patients with active systemic lupus erythematosus (SLE). At Week 52, significant reductions in SLE disease activity were observed based on multiple clinical measures, including the patient response rate chosen as the primary efficacy endpoint of the Phase 3 trials. Continued improvements were observed from Week 52 through Week 76 in the 24-week extension phase of the trial. The data also suggested that LymphoStat-B was well tolerated and improved quality of life in patients with active SLE. In the second quarter, HGS initiated dosing in the second of two pivotal Phase 3 trials of LymphoStat-B. Both trials are expected to enroll patients throughout 2007, with completion of enrollment anticipated in 2008. LymphoStat-B is being developed by HGS and GSK under a definitive development and commercialization agreement entered into in August 2006. TRAIL Receptor Antibodies In April 2007, the Journal of Clinical Oncology published the results of the first human study of HGS-ETR1 (mapatumumab) along with a positive editorial. HGS is currently enrolling patients in a randomized Phase 2 trial of HGS-ETR1 in combination with Velcade (bortezomib) in patients with advanced multiple myeloma. Clinical and preclinical evidence continues to emerge suggesting that HGS-ETR1 and HGS-ETR2 (lexatumumab) have significant potential for use in the treatment of a broad range of cancers. HGS is in the planning stages of additional studies of its TRAIL receptor antibodies in randomized combination trials, and will report on their progress in the months ahead. Facilities Consolidation In May 2007, HGS completed the purchase and sale of a 51,000 square-foot laboratory facility for a net gain of $1.7 million. In addition, as a result of these transactions in the second quarter, the Company recorded a reversal of $2.0 million in previously accrued non-cash exit charges. HGS vacated the facility and subleased it to Novavax, Inc. in 2006. CONFERENCE CALL HGS management will hold a conference call to discuss this announcement today at 11 AM Eastern.
