The primary objective of this study is to evaluate the long-term safety and tolerability of litifilimab in participants with active systemic lupus erythematosus (SLE). The secondary objectives of this study are to evaluate the long-term effect of litifilimab on disease activity in participants with SLE, to evaluate the long-term effect of litifilimab in participants with SLE in maintaining low disease activity, to evaluate the effect of litifilimab in participants with active SLE in preventing irreversible organ damage, to assess long-term use of oral corticosteroid (OCS) with participants receiving litifilimab treatment, to assess the impact of litifilimab on participant-reported Health-Related Quality-of-Life Questionnaire (HRQoL), symptoms, and impacts of SLE, to evaluate long-term effect of litifilimab on laboratory parameters, and to evaluate immunogenicity of litifilimab.
This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to insulin icodec taken once a week in people with type 2 diabetes. The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to insulin icodec. Participants will either get IcoSema or insulin icodec. Which treatment participants get is decided by chance. IcoSema and insulin icodec are both new medicines that doctors cannot prescribe. Participants will get IcoSema or insulin icodec, which participants must inject once a week with a pen, which has a small needle, in a skin fold in the thigh, upper arm, or stomach. The study will last for about 1 year and 1 month. Participants will have 21 clinic visits, 31 phone/video calls with the study doctor, and 4 contacts with the site that can either be clinic visits or phone/video calls At 11 clinic visits participants will have blood samples taken. At 7 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit. Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period. Not applicable for China: Participants will be asked to wear a sensor that measures their blood sugar level all the time during a 5 week period at the end of the study.
This is a multinational non-interventional study based on newly collected data to assess demographics, disease, and treatment pattern of patients with chronic Heart Failure (HF) in a two-cohort design: one cohort will receive first prescription of empagliflozin as routine therapy for HF, the other cohort will receive HF therapy with drugs with another mechanism of action. Treatment of HF according to routine practice is determined by the physician independent of the participation of the patient in this non-interventional study.
