Still's Disease, Adult-Onset

STOCKHOLM, Oct. 30, 2024 /PRNewswire/ -- Sobi® (STO: SOBI) today announced that new research showing the effect of emapalumab in patients with macrophage activation syndrome (MAS) in Still's disease, including systemic juvenile idiopathic arthritis (sJIA) and adult-onset still's disease (AOSD) who had an inadequate response to high-dose glucocorticoids (GCs) will be presented at the American College of Rheumatology (ACR) Convergence in Washington D.C. The data were pooled from two open-label, single-arm interventional studies, the phase 3 NI-0501-14 study [EMERALD; NCT05001737] and NI-0501-06 [NCT03311854], including 39 patients with MAS. Key results: Complete response at week 8: At week 8, 21 patients (53.8%) achieved a complete response (95% confidence interval (CI): 37.2–69.9%). Complete response at any time: 33 patients (85%) achieved a complete response at any time during the studies. Glucocorticoid tapering: Weekly mean glucocorticoid doses were reduced by 70.1% after 2 weeks of treatment. By week 8, glucocorticoids were tapered to a clinically meaningful dose of ≤1 mg/kg/day in 28 patients (72%) and to ≤0.5 mg/kg/day in 17 patients (44%). Safety: No new safety concerns were identified during the studies. "MAS in Still's disease is a severe condition characterised by intense hyperinflammation and multiple organ failure. Those affected, including young children, often experience high fevers, liver and spleen enlargement, severe cytopenias, and neurological symptoms," said Lydia Abad-Franch, MD, Head of Research & Development and Medical Affairs and Chief Medical Officer at Sobi. "The results to be presented at ACR indicate that emapalumab could potentially provide a new therapeutic option, offering effective control of MAS symptoms and possibly reducing the need for high-dose glucocorticoids. This represents an important development in the treatment landscape for MAS." Additional key results: Overall response (OR) by week 8: 32 patients (82.4%) achieved an overall response by week 8. OR was observed as early as day 5, with a median time to first OR of 2.3 weeks. Clinical MAS remission: 32 patients (82.1%) achieved investigator-assessed clinical MAS remission at any time , with a median time to clinical remission of 3.3 weeks. Survival rate: 37 patients (94.9%) were alive at week 8. Emapalumab is a monoclonal antibody that neutralises interferon gamma (IFNγ), a key cytokine which contributes to the inflammation and tissue damage seen in MAS. The purpose of these two prospective studies is to assess the efficacy and safety of emapalumab in controlling MAS in patients with Still's disease, including sJIA and AOSD, who had an inadequate response to high-dose glucocorticoids. In May 2024, the US FDA granted emapalumab fast track designation as a potential therapeutic option in patient with MAS. Sobi plans to submit an sBLA for this indication to the FDA in 2024. The data will be presented by Alexei A. Grom, MD, Professor of Paediatrics, Research Director Division of Rheumatology, Cincinnati Children's Hospital Medical Centre, in a session entitled "Efficacy and Safety of emapalumab in children and adults with macrophage activation syndrome (MAS) in Still's disease: Results from a phase 3 study and a pooled analysis of two prospective trials" on Tuesday, 19 November at ACR Convergence. About macrophage activation syndrome (MAS) Macrophage activation syndrome (MAS) is a severe complication of rheumatic diseases, most frequently systemic juvenile idiopathic arthritis (sJIA) – a rare systemic disorder of auto-inflammatory nature with common clinical manifestations such as daily spiking fever, typical transient cutaneous rash, arthritis, lymphadenopathy, hepatosplenomegaly and serositis. MAS is characterised by fever, hepatosplenomegaly, liver dysfunction, cytopenias, coagulation abnormalities and hyperferritinaemia, possibly progressing to multiple organ failure and death. MAS is classified as a secondary form of haemophagocytic lymphohistiocytosis (HLH). About emapalumab Emapalumab (Gamifant®) is an anti-interferon gamma (IFNγ) monoclonal antibody that binds to and neutralises IFNγ. In the USA, emapalumab is indicated for the treatment of adult and paediatric (newborn and older) patients with primary haemophagocytic lymphohistiocytosis (HLH) with refractory, recurrent or progressive disease or intolerance with conventional HLH therapy. Primary HLH is a rare syndrome of hyperinflammation that usually occurs within the first year of life and can rapidly become fatal unless diagnosed and treated. The FDA approval is based on data from the phase 2/3 studies (NCT01818492 and NCT02069899). Gamifant is indicated for administration through intravenous infusion over one hour twice per week until haematopoietic stem cell transplantation (HSCT).

Results showed that MAS remission was seen in 13 of 14 patients with sHLH/MAS receiving emapalumab who had an inadequate response to high-dose glucocorticosteroidsWALTHAM, Mass., April 04, 2023 (GLOBE NEWSWIRE) -- Sobi North America, the North American affiliate of Swedish Orphan Biovitrum AB (Sobi®) (STO:SOBI), today announced that the Annals of Rheumatic Diseases has published results from an open-label, single-arm, multicenter phase 2 study evaluating the safety and efficacy of emapalumab, an anti-interferon-gamma monoclonal antibody, being investigated in patients with Systemic Juvenile Idiopathic Arthritis (sJIA) or Adult-onset Still's Disease (AOSD) who developed secondary hemophagocytic lymphohistiocytosis (sHLH)/Macrophage Activation Syndrome (MAS) following an inadequate response to high-dose glucocorticosteroids. In the published study, 14 patients with sJIA or AOSD and sHLH/MAS who did not respond to high-dose glucocorticosteroids received emapalumab. MAS remission was seen in 13 of the 14 patients by week 8, at a median time of 25 days, based on clinical and laboratory criteria. All 14 patients completed the trial, entered long-term follow-up and were alive at the end of follow-up. Based on the results of this study, Sobi decided to continue to evaluate emapalumab in this patient population and initiated the EMERALD phase 3 study, which is ongoing. "I believe that the results of this study represent an important milestone for the identification of a potential novel targeted treatment for patients with sJIA or AOSD with sHLH/MAS who have failed high-dose glucocorticoids," said Dr. Fabrizio De Benedetti, Head of the Division of Pediatric Rheumatology and Head of the Laboratory of ImmunoRheumatology at Bambino Gesù Children's Hospital in Rome, Italy. "We are eager to collect more data so that emapalumab becomes part of the therapeutic armamentarium for this rare disease and its high unmet medical need." sHLH/MAS is a rare, life-threatening condition characterized by uncontrolled hyperinflammation which may develop on a background of rheumatologic diseases such as sJIA. It is classified as a secondary form of HLH and is caused by excessive activation and expansion of T cells and macrophages. A body of scientific evidence has been accumulated suggesting interferon gamma (IFNγ) is a major driver of hyperinflammation in diseases such as sHLH/MAS. “The results published in the Annals of Rheumatic Diseases are encouraging for patients with sJIA or AOSD developing sHLH/MAS, who have had an inadequate response to high dose glucocorticoid treatment,” said Dr. Alexei Grom, Research Director, Division of Rheumatology and Professor of Pediatrics at Cincinnati Children's Hospital Medical Center, in Cincinnati, Ohio. “The ability of emapalumab to achieve MAS remission is meaningful as there is a high unmet need for these patients.” “We are pleased that this newly published clinical data shows the potential benefit of emapalumab in patients with secondary HLH,” said Tony Hoos, Head of Research & Development and Medical Affairs, Chief Medical Officer at Sobi. “We remain committed to evaluating emapalumab as a potential new treatment option for patients affected by this severe condition. If our ongoing EMERALD phase 3 study in sHLH/MAS confirms the benefit, we are intending to file a supplemental Biologics License Application.” Emapalumab is marketed in the United States as Gamifant® and is indicated for the treatment of adult and pediatric (newborn and older) patients with primary hemophagocytic lymphohistiocytosis (HLH) with refractory, recurrent or progressive disease or intolerance with conventional HLH therapy.Gamifant has not been reviewed or approved by the U.S. Food and Drug Administration for sHLH/MAS.ContactsFor details on how to contact the Sobi Investor Relations Team, please click here.
