  June 7 - Human Genome Sciences, Inc.  (Nasdaq: HGSI) today announced the top-line final results of a Phase 2b  clinical trial of Albuferon (albinterferon alfa-2b) in combination with  ribavirin in treatment-naive patients with genotype 1 chronic hepatitis C. The  Company expects to make a full presentation of the final results at an appropriate  scientific meeting later in 2007.

  "The final Phase 2b results confirm and extend the  findings of several studies, which suggest that Albuferon may offer efficacy at  least comparable to peginterferon alfa-2a, with half the injections and  possibly less impairment of quality of life," said John McHutchison, M.D.,  Coordinating Center Principal Investigator for the Phase 2b trial, and  Professor of Medicine and Associate Director, Duke Clinical Research Institute  and Duke University Medical Center, Durham, North Carolina. "We are  extremely pleased with the high quality of the data that have emerged from the  Phase 2b study, and we look forward to continuing the evaluation of the 900-mcg  and 1200-mcg doses of Albuferon in larger populations in Phase 3 trials."
 
  The primary efficacy endpoint of the Phase 2b trial of  Albuferon was sustained virologic response (SVR), defined as undetectable viral  load (HCV RNA<10 IU/mL) at 24 weeks following completion of therapy. The  final results demonstrated that Albuferon provided at least comparable efficacy  vs. Pegasys (peginterferon alfa-2a), based on an ITT analysis. The treatment  group receiving Albuferon 900-mcg doses every two weeks achieved an SVR rate of  58.5%, vs. 57.9% for the group receiving Pegasys once every week (ITT  analysis). This Albuferon treatment group also had more favorable health-  related quality-of-life scores than the Pegasys treatment group. Among heavier  patients (>75 kg) who were treatment-adherent, 71.2% of those in the  combined groups receiving Albuferon every two weeks achieved SVR, versus 53.3%  for patients receiving Pegasys once a week. The ability to maintain efficacy in  heavier patients is of particular importance in certain markets, including the  United States, where a large percentage of patients weigh more than 75 kg.
 
  Top-Line Final Results by Treatment Group
 
  The top-line final results of the Phase 2b trial at Week 24  following the completion of therapy include the following SVR rates and other  findings: Albuferon 900-mcg Every Two Weeks (Albuferon 900 Q2w)
 
  -- Based on an intention-to-treat (ITT) analysis, 58.5% of  patients in the Albuferon 900 Q2w treatment group achieved SVR, vs. 57.9% for  Pegasys administered every week.
 
  -- In heavier patients (>75 kg) who were  treatment-adherent, 74.2% of those in the Albuferon 900 Q2w treatment group  achieved SVR, versus 53.3% for Pegasys.
 
  -- Among all treatment-adherent patients in the Albuferon 900  Q2w treatment group, 72.3% achieved SVR, versus 66.7% for Pegasys.
 
  -- Based on the SF-36 Health Survey, patients in the Albuferon  900 Q2w treatment group reported less impairment of health-related quality of  life, compared with patients in the Pegasys treatment group, as measured by both  physical component and mental component SF-36 summary measures at all  time-points throughout the 48-week treatment period.
 
  -- Fewer working patients in the Albuferon 900 Q2w treatment  group reported missing 7 days or more of work during the month prior to their  visits at Weeks 12 and 24, vs. the Pegasys group (Week 12: 3.0% for Albuferon  900 Q2w vs. 19.2% for Pegasys; Week 24: 5.8% for Albuferon 900 Q2w, vs. 22.4%  for Pegasys).
 
  -- The rate of discontinuations due to adverse events was 9.3%  in the Albuferon 900 Q2w treatment group, vs. 6.1% in the Pegasys group.
 
  "The 900-mcg Albuferon dose has the potential to offer  patients an attractive therapeutic option, requiring half as many injections as  Pegasys, with more favorable quality of life effects and favorable sustained  virologic response data," said David C. Stump, M.D., Executive Vice  President, Research and Development, HGS.
 
  Albuferon 1200-mcg Every Two Weeks (Albuferon 1200 Q2w)
 
  -- ITT analysis shows that 55.5% of patients in the Albuferon  1200 Q2w treatment group achieved SVR, vs. 57.9% for Pegasys administered every  week.
 
  -- In heavier patients (>75 kg) who were  treatment-adherent, 67.9% of those in the Albuferon 1200 Q2w treatment group  achieved SVR, versus 53.3% for Pegasys every week.
 
  -- Among all treatment-adherent patients in the Albuferon 1200  Q2w treatment group, 70.6% achieved SVR, versus 66.7% for Pegasys.
 
  -- ITT analysis shows that the Albuferon 1200 Q2w treatment  group exhibited a robust early antiviral response (reduction in hepatitis C RNA  viral load to below the level of quantitation): 74.5% for Albuferon 1200 Q2w at  Week 12, vs. 65.8% for Pegasys. The Albuferon 1200 Q2w treatment group also had  the most rapid time to HCV RNA negativity.
 
  -- The rate of discontinuations due to adverse events was  18.2% in the Albuferon 1200 Q2w treatment group, vs. 6.1% in the Pegasys group.  Adverse events observed were those typically expected with interferon therapy.  Dose reductions were attempted in only 30.0% of Albuferon subjects prior to  discontinuation, versus 42.9% for Pegasys.
 
  "In the Albuferon Phase 3 trials, we will strongly  encourage titration of dose where necessary to ensure tolerability, reduce the  rate of discontinuations, and maximize the therapeutic benefit of the robust early  antiviral response offered by the 1200-microgram dose on a two-week  administration schedule," said Dr. Stump.
 
  Albuferon 1200-mcg Monthly (Albuferon 1200 Q4w)
 
  -- ITT analysis shows that 50.9% of patients in the Albuferon  1200 Q4w treatment group achieved SVR, vs. 57.9% for Pegasys administered every  week.
 
  -- In heavier patients (>75 kg) who were  treatment-adherent, 61.0% of those in the Albuferon 1200 Q4w treatment group  achieved SVR, versus 53.3% for Pegasys administered once every week.
 
  -- Among all treatment-adherent patients in the Albuferon 1200  Q4w treatment group, 62.0% achieved SVR, versus 66.7% for Pegasys.
 
  -- The rate of discontinuations due to adverse events was  12.1% in the Albuferon 1200 Q4w treatment group, vs. 6.1% in the Pegasys group.
 
  -- The number of patients experiencing severe hematologic  adverse events was significantly lower in the Albuferon 1200 Q4w treatment  group(10.3%, vs. 23.7% for Pegasys, p=0.006).
 
  "We are encouraged that more than half of the patients  achieved sustained virologic response in the treatment group receiving  Albuferon 1200-mcg once every month," said Dr. Stump. "These data,  along with emerging Phase 2 data for a monthly 1500-mcg dose, provide an  excellent rationale for the study that we and our collaborator, Novartis, are  currently planning to evaluate higher doses of Albuferon administered  monthly."
 
  The top-line final Phase 2b results include data through Week  24 following completion of 48 weeks of therapy. The open-label, multi-center,  active- controlled, dose-ranging trial enrolled and randomized 458 patients  with genotype 1 chronic hepatitis C. Patients were randomized into four  treatment groups, three of which received subcutaneously administered Albuferon  (900 mcg every two weeks, 1200 mcg every two weeks, and 1200 mcg every four  weeks). The fourth treatment group served as the active control group and  received 180 mcg of subcutaneously administered peginterferon alfa-2a (Pegasys)  once a week. All patients received weight-based oral ribavirin daily. The study  was conducted in Australia, Canada, Czech Republic, France, Germany, Israel,  Poland and Romania.
 
  About Albuferon
 
  Albuferon is a novel long-acting form of interferon alpha  created by HGS using its proprietary albumin fusion technology. Albuferon  results from the genetic fusion of human albumin and interferon alpha. Human  albumin is the most prevalent naturally occurring blood protein in the human  circulatory system, persisting in circulation in the body for over twenty days.  Research has shown that genetic fusion of therapeutic proteins to human albumin  decreases clearance and prolongs the half-life of the proteins. Recombinant  interferon alpha is approved for the treatment of hepatitis C, hepatitis B and  a broad range of cancers.
 
  Albuferon is being developed by HGS and Novartis under an  exclusive worldwide development and commercialization agreement entered into in  June 2006. Under the agreement, HGS and Novartis will co-commercialize  Albuferon in the United States, and will share clinical development costs, U.S.  commercialization costs and U.S. profits equally. Novartis will be responsible  for commercialization in the rest of the world and will pay HGS a royalty on  those sales. Clinical development, commercial milestone and other payments to  HGS could total as much as $507.5 million, including $92.5 million received to  date.
 
  About Hepatitis C
 
  Hepatitis C is an inflammation of the liver caused by the  hepatitis C virus. It is estimated that as many as 170 million people worldwide  are infected with hepatitis C virus. This includes nearly four million people  in the United States. When detectable levels of the hepatitis C virus in the  blood persist for at least six months, a person is diagnosed as having chronic  hepatitis C. The hepatitis C virus can cause serious liver disease in a  significant proportion of infected individuals, leading to cirrhosis, primary  liver cancer, and even death.
 
  About Human Genome Sciences
 
  The mission of HGS is to apply great science and great  medicine to bring innovative drugs to patients with unmet medical needs.
 
  The HGS clinical development pipeline includes novel drugs to  treat hepatitis C, lupus, anthrax disease, cancer, rheumatoid arthritis and  HIV/AIDS. The Company's primary focus is rapid progress toward the  commercialization of its two lead compounds, Albuferon for hepatitis C, and  LymphoStat-B for lupus. Phase 3 clinical trials of both compounds are now  underway.
 
  In June 2006, HGS announced that the U.S. Government exercised  its option under an existing contract to purchase 20,000 doses of ABthrax(TM)  for the treatment of anthrax disease. Other HGS drugs in clinical development  include two TRAIL receptor antibodies for the treatment of hematopoietic and  solid malignancies, in addition to an antibody to the CCR5 receptor for the  treatment of HIV/AIDS.
