It reviews the ongoing randomized clinical trials of the drug in IgA nephropathy (IgAN) and focal segmental glomerulosclerosis (FSGS) as well as studies in pediatric patients and outlines the potential role of sparsentan in the future management of patients with proteinuric kidney disease. There is abundant evidence supporting the role of angiotensin II (AngII) and endothelin-1 (ET-1) signaling in the pathogenesis and perpetuation of glomerular injury. These vasoactive molecules act on mesangial and endothelial cells and podocytes, causing a variety of pathological changes in glomeruli, leading to proteinuria, and ultimately progressive glomerulosclerosis. Moreover, these signaling cascades interact with one another underscoring the potential application of sparsentan, a novel non-immunosuppressive dual endothelin and angiotensin receptor antagonist (DEARA) that blocks AT1 and Endothelin Type A (ETA) receptor activation The preclinical and clinical evidence supporting the use of dual AT1/ETA receptor inhibition over monoblockers of AngII or ET-1 actions in the treatment of kidney diseases has been reviewed by Komers and Plotkin [1]. Recent findings reinforce the value of specifically inhibiting ET-1 in patients with glomerular disease. Endothelin gene expression is elevated in patients with glomerular disease such as IgA nephropathy and an increased risk of disease progression [2]. Preclinical studies with sparsentan demonstrated a spectrum of antiproliferative, anti-inflammatory, antifibrotic, and podocyteprotective actions of the drug in different models of kidney disease including FSGS, IgAN, and Alport syndrome [3–6]. A novel protective mechanism of sparsentan in FSGS was recently suggested by Li et al. [7]. The abundance of tissueresident lymphocytes and the proportion of CD8 TRM cells are increased in kidneys from patients with FSGS. Sparsentan reduced TRM cell responses by inhibiting Ang II and/or ET1-mediated IL-15 signaling, thereby further regulating renal CD8 TRM cell accumulation in the kidney [5]. ETA receptor expression is increased in kidney biopsy specimens obtained from patients with FSGS, and the intensity is directly related to nephron loss and oxidative damage. The degree of oxidative stress is, in turn, associated with proteinuria [8,9]. 2.

PCOS is characterized by a complex interplay of hormonal, metabolic, and reproductive disturbances. The syndrome’s underlying changes impact multiple systems, leading to several and complex clinical manifestations. One of the hallmark features of PCOS is hyperandrogenism which brings on symptoms like excessive hair growth, acne and alopecia. Anovulation and irregular menstrual cycles stem from the imbalance in follicle-stimulating hormone (FSH) and luteinizing hormone (LH) triggered by androgen fluctuations. PCOS often involves both hyperandrogenism and insulin resistance, due to reduced sensitivity of target cells. These metabolic conditions over time lead to increased risk of type 2 diabetes, obesity, and dyslipidemia development. The interplay between insulin resistance and hyperandrogenism intensifies the syndrome’s clinical symptoms. Abnormal gonadotropin-releasing hormone (GnRH) secretion has consequences of ovarian anovulation and cyst formation, resulting in unbalanced FSH and LH production.","PeriodicalId":12292,"journal":{"name":"Expert Opinion on Emerging Drugs","volume":" ","pages":"149-152"},"PeriodicalIF":3.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41118997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
