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.

This is a randomized, placebo-controlled, study of SPI-62 in subjects with ACTH-dependent Cushing's syndrome caused by a non-adrenal tumor. Subjects will receive each of the following 2 treatments for 24 weeks: SPI-62 and matching placebo with the option of long-term extension.
Study RNLC3132 is a Phase 3, randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of rifaximin SSD-40mg IR for the delay of the first episode of overt hepatic encephalopathy (OHE) decompensation in liver cirrhosis, defined by the presence of medically controlled ascites.
This study will assess the safety, efficacy and immune response following the sequential treatment of GlaxoSmithKline's (GSK) ASO compound (GSK3228836) and CHB-TI (GSK3528869A) in participants 18 to 65 years stable on NA treatment for CHB. The aim is to quantify the efficacy of sequential therapy as well as to determine an added value of sequential therapy over GSK3228836 therapy in CHB patients treated with NAs. In addition, the study will assess the effect of different treatment durations of GSK3228836 (12 or 24 weeks) prior to initiating GSK3528869A treatment.

This is a Phase IIIb, single-arm, multicenter, OLE study. Participants receiving ocrelizumab as an investigational medicinal product (IMP) in a Roche sponsored Parent study who continue to receive ocrelizumab or are in safety follow-up at the time of the closure of their respective Parent study (WA21092, WA21093 or WA25046) are eligible for enrollment in this extension study. Participants who will continue ocrelizumab treatment will receive IMP based on the dosage and administration received at the time of rollover from the Parent study.
