HAYWARD, Calif., June 4, 2015 -- Anthera Pharmaceuticals, Inc. (ANTH), a biopharmaceutical company focused on advancing the development and commercialization of innovative medicines that benefit patients with unmet medical needs, today announced that additional data from its Phase 2b PEARL-SC study will be presented in a poster at the European League Against Rheumatism (EULAR) Annual European Congress of Rheumatology in Rome, Italy.

As part of a guided poster tour on June 6^th, 2015, Dr. Michelle Petri, Director of the Hopkins Lupus Center at Johns Hopkins University, will present breaking data on the impact of treatment with blisibimod on patient-reported fatigue and improvement in disease biomarkers.

"Effects of Blisibimod, an Inhibitor of B Cell Activating Factor, on Patient Reported Outcomes and Disease Activity in Patients with Systemic Lupus Erythematosus"

Treatment with blisibimod was associated with statistically significant and clinically meaningful improvements in patient-reported fatigue, as measured by the FACIT-fatigue scale, over a similar time course as the SRI and SLE biomarker response rates. These effects were most evident at the highest dose of blisibimod (200mg QW). The FACIT-fatigue scale is a measure of health-related quality of life with a specific focus on fatigue, tiredness and weakness.
