FDA approves Opsumit to treat pulmonary arterial hypertension

The U.S. Food and Drug Administration today approved Opsumit (macitentan), a new drug to treat adults with pulmonary arterial hypertension (PAH), a chronic, progressive and debilitating disease that can lead to death or the need for lung transplantation.

Conclusions and Perspectives In this review, we have discussed important milestones from the early description of “Serum-sickness” as being due to antibodies directed against Neu5Gc epitopes all the way to the present-day therapeutic implications of these antibodies in cancer therapy. Some of these milestones have been represented in a concise timeline (Figure 6). While the “Xenosialitis” hypothesis is well-supported in the human-like mouse models, it has yet to be conclusively proven in humans. It remains to be seen if “Xenosialitis” plays a role in other uniquely-human diseases. FI...

In this study, we found that senescent chondrocytes isolated from OA patients secrete more EVs compared with nonsenescent chondrocytes. These EVs inhibit cartilage ECM deposition by healthy chondrocytes and can induce a senescent state in nearby cells. We profiled the miR and protein content of EVs isolated from the synovial fluid of OA joints from mice with SnCs. After treatment with a molecule to remove SnCs, termed a senolytic, the composition of EV-associated miR and protein was markedly altered. The senolytic reduced OA development and enhanced chondrogenesis, and these were attributable to several specific differenti...

In this study, we used HUT as the means to provide an all-encompassing assessment of cardiac and/or peripheral autonomic function in normal controls, SCD subjects and non-SCD subjects with chronic anemia. We hypothesized that by identifying different categories of HUT response among these subjects, we would be able to isolate the autonomic phenotypes that might place SCD subjects at increased risk for microvascular occlusion and VOC. We then employed the causal modeling approach, which utilizes signal analysis and system identification techniques, to probe and disentangle the functional mechanisms involved in the cardiovas...

In this study the effect of NMP perfusion fluid on survival, metabolism and function of thawed cryopreserved human (h)MSC and porcine (p)MSC in suspension conditions was studied. Suspension conditions reduced the viability of pMSC by 40% in both perfusion fluid and culture medium. Viability of hMSC was reduced by suspension conditions by 15% in perfusion fluid, whilst no differences were found in survival in culture medium. Under adherent conditions, survival of the cells was not affected by perfusion fluid. The perfusion fluid did not affect survival of fresh MSC in suspension compared to the control culture medium. The f...

Primary graft dysfunction (PGD) is a major cause of morbidity and mortality after lung transplantation. Its incidence has decreased with optimization of lung preservation strategies. It remains, however, an important problem, particularly in patients with pulmonary fibrosis and pulmonary hypertension.1 Its development is generally multifactorial and thus referred to as a syndrome. Biologically, activation of the innate immune system and increased endothelial permeability are the main drivers of pulmonary capillary leak after reperfusion.

This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

Publication date: Available online 20 March 2019Source: CytotherapyAuthor(s): Pengbo Wang, Caixin Zhang, Jun Li, Lin Luo, Shuwen Zhang, Fulu Dong, Zhiyuan Tang, Songshi NiAbstractPulmonary arterial hypertension (PAH) is characterized by pulmonary arterial endothelial hyperproliferation and dysfunction. Restoration of endothelial function is a common goal of available treatments. In the present study, human adipose-derived mesenchymal stromal cells (ASCs) were co-cultured with monocrotaline pyrrole–treated human pulmonary arterial endothelial cells (HPAECs); increased proliferation of HPAECs and expression of vascular...

Inhalational drug delivery to treat PAH is attractive due to enhanced pulmonary specificity and reduced systemic adverse effects. LIQ861 is a dry powder formulation of Treprostinil (TRE) designed to enhance deep-lung delivery and achieve higher tolerated dose levels than current inhaled therapies. LIQ861 ’s uniform (1µm) particle size with a trefoil, pollen-like shape, enables QID delivery of TRE doses in a convenient, palm-sized, disposable dry powder inhaler (DPI). The primary objective of the INSPIRE study is the safety and tolerability of LIQ861 in subjects transitioning from stable doses of Tyvaso® or ...
