Human Genome Sciences and GlaxoSmithKline Announce Positive Phase 3 Study Results for BENLYSTA™
News Jul 20, 2009
Human Genome Sciences, Inc. and GlaxoSmithKline PLC (GSK) announced that BENLYSTA™ (belimumab, formerly LymphoStat-B) met the primary endpoint in BLISS-52, the first of two pivotal Phase 3 trials in patients with serologically active systemic lupus erythematosus (SLE).
In the placebo-controlled BLISS-52 study, the results showed that belimumab plus standard of care achieved a clinically and statistically significant improvement in patient response rate at Week 52, compared with standard of care alone. Study results also showed that belimumab was generally well tolerated, with adverse event rates comparable between belimumab and placebo treatment groups.
"The BLISS-52 results demonstrated that BENLYSTA has the potential to become the first new approved drug in decades for people living with systemic lupus," said H. Thomas Watkins, President and Chief Executive Officer, HGS.
"Given the limited treatment options currently available, patients would benefit greatly from potential new treatments. BENLYSTA is an outstanding example of the type of treatment HGS is working to develop and bring to patients. Assuming positive results in November from our second Phase 3 trial of BENLYSTA, we and GSK plan to submit marketing applications in the United States, Europe and other regions in the first half of 2010."
Belimumab is an investigational drug and the first in a new class of drugs called BLyS-specific inhibitors. No new drug for lupus has been approved by regulatory authorities in more than 50 years. Belimumab is being developed by HGS and GSK under a co-development and commercialization agreement entered into in August 2006.
"Lupus is a chronic, often debilitating, and sometimes fatal illness that affects an estimated five million people worldwide and can have a devastating effect on both patients living with the disease and their families," said Carlo Russo, M.D., Senior Vice President, Biopharm Development, GSK.
"BENLYSTA is the first medicine being developed specifically for lupus that has reached this late stage of clinical development with positive results. We look forward to completing the pivotal studies, with the hope of bringing this potentially important therapeutic advance to patients suffering from SLE."
Biochemists, microbiologists, drug discovery experts and infectious disease doctors have teamed up in a new study that shows antibiotics are not always necessary to cure sepsis in mice. Instead of killing causative bacteria with antibiotics, researchers treated infected mice with molecules that block toxin formation in bacteria.READ MORE
Previous work by the International Multiple Sclerosis Genetics Consortium (IMSGC) has identified 233 genetic risk variants. However, these only account for about 20% of overall disease risk, with the remaining genetic culprits proving elusive. A new study has tracked down four of these hard-to-find genes.READ MORE
The sweet flavors’ appeal to teens is a major concern for Food and Drug Administration officials, who recently declared teen vaping an epidemic. New research shows flavorings are transforming more than marketing. The chemical additives react to e-liquid, or e-juice, creating new compounds that could trigger irritation and inflammation when inhaled.READ MORE
