NEW YORK (Reuters) - Human Genome Sciences Inc. on Wednesday said its experimental monoclonal antibody belimumab (LymphoStat-B) for rheumatoid arthritis significantly reduced symptoms in a mid-stage trial of patients with moderate to severe forms of the disease.
The biotechnology company said the positive results were seen in a phase II trial of 283 patients in the United States and Poland who had previously failed to benefit from standard drugs.
The company, based in Rockville, Maryland, said 36% of patients taking the lowest dose of belimumab achieved at least a 20% improvement in symptoms after 24 weeks. By contrast, only 17% of patients receiving placebo reported comparable pain relief, the company said.
All patients continued to receive standard treatments, including up to two disease-modifying drugs, prednisone and methotrexate.
Patients who received belimumab took one of three doses, while others instead added intravenous placebo infusions to their standard treatments over the 24-week trial period.
Patients receiving the two higher doses of the Human Genome Sciences drug, however, did not show a statistically significant improvement.
The company said its drug was well tolerated, with no significant differences from placebo in side effects.
Human Genome Sciences is also testing the drug against lupus.
