Tricuspid valve regurgitation has lagged mitral regurgitation where device development is concerned, but new one-year data from the TRILUMINATE study of the Triclip device suggests that device therapy is safe and cuts down on regurgitation in a manner that makes the condition much more tolerable for patients. At this point, however, the data do not yet offer much difference when it comes to mortality and rehospitalization compared to medical management, a gap Abbott will have to overcome if it wants to maximize its investment in this underdeveloped area of medical technology.
Abbott Laboratories scored a major win for its Mitraclip device thanks to data from the COAPT study for secondary mitral valve regurgitation. The latest data from this study show a stunning difference in two-year mortality compared to maximized medical management only – 29% on the device versus 46% on medical management – but differences between the COAPT study results and outcomes seen in the MITRA-FR study will force cardiologists to dive into the data to ensure that their patient selection practices account for critical differences in the conduct of these two studies.
The U.S. Recover program, set up in July 2022 to identify the causes of long COVID, find biomarkers of disease and discover new therapeutic targets, is now preparing to move to its next phase and begin testing potential treatments in a multi-arm, randomized, placebo-controlled trial. But with 200 different symptoms, and limited understanding of relevant system-level pathological targets, there are significant hurdles to be overcome.
Since episodes of idiopathic anaphylaxis (IA) are often accompanied by gastrointestinal (GI) manifestations, researchers from the National Institutes of Health aimed to investigate whether surrogate markers of GI permeability are aberrant in patients with IA.
In a striking demonstration of how the success of mRNA vaccines against COVID-19 has opened up the potential of the technology in cancer, mice that cleared a tumor after a single administration of an mRNA vaccine, also cleared a second tumor without receiving further immunization. This display of potent immunogenicity formed part of a head-to-head study of three different mRNA technology platforms in human papillomavirus (HPV)-16 associated tumors.
The fundraising environment for startups in med tech is expected to continue to be challenging for at least another year as public markets remain closed and private investors favor companies that have already de-risked their products. One of the major issues in the U.K. and Europe is that the IPO markets are “pretty much shut” and “our public markets aren’t working”, therefore companies are having to rely on private funding, with venture capital being one of those sources, said Robert Tansley, partner, at venture capital fund Cambridge Innovation Capital (CIC).
According to venture capitalists on three different panels at Biocom California’s Global Life Science Partnering & Investor Conference, there’s still money available for newcos looking to get started. But the pitch they’re going to have to make to VCs is a little different than what would have worked a few years ago.
Allogeneic mesenchymal stromal cell (MSC) therapy is well tolerated in patients with graft-vs.-host disease (GVHD) but results in clinical trials have shown that it lacks potent immunosuppressive effects. Researchers from the Mayo Clinic thus proposed enhancing MSC immunosuppression by bioengineering the first chimeric antigen receptor (CAR) MSCs (CAR-MSCs) and targeting E cadherin (anti-Ecad CAR-MSC), with a CD28 intracellular signaling domain to induce antigen-specific immunosuppressor effect.
Obesity is tied to airway hyperresponsiveness and lung fibrosis, which may lead to patients with asthma and obesity poorly responding to asthma therapy. Blocking proprotein convertase subtilisin/kexin type 9 (PCSK9) is known to reduce serum cholesterol levels and to exert anti-inflammatory effects.
