Black Patients with ICDs Have Higher Rate of Post-Implant Cardiac Events and Risk of Death

Black patients with implantable cardioverter defibrillators (ICDs) have a significantly higher burden of disease than white patients with the same device, according to a new study from University of Rochester Medical Center (URMC) cardiology researchers. Analyzing data from clinical trials conducted over a 20-year period by the Clinical Cardiovascular Research Center (CCRC) at URMC, investigators concluded that not only did Black patients with ICDs tend to be significantly younger than white patients, but they also had a higher rate of post-implant cardiac events and risk of death. When a patient is at risk for cardiac arrest, an ICD helps to monitor their heart rhythm, and if an abnormality is detected, the device delivers a shock of electricity to reset the heartbeat to a normal rhythm. The study, published in Circulation, examines the rate of events that a patient experiences after their ICD is implanted. After three years of ...

DNA Origami Could Be Used to Create Customized Virus-Like Particles

Bioengineers have found a way to program the size and shape of virus particles by combining viral protein building blocks and templates made from DNA. The resulting nanostructures could have applications in vaccine development and transporting drugs inside the body. Virus capsid proteins-;the proteins that shield the genome of a virus-;can be used to build precisely structured protein assemblies. Their shapes and geometry, however, depend largely on the virus strain. Reprogramming these assemblies, no matter the original viral blueprint, is an intriguing possibility for drug delivery and vaccine development. Scientists tackled the challenge by generating a “structured genome” template on which capsid proteins can assemble. To avoid deforming the flexible genome and creating unintended shapes, they used rigid DNA origami structures. These structures are only tens to hundreds of nanometres in length, but entirely made of DNA, which is folded accurately into the desired template shape. ...

Experts Flag Eye Inflammation Reports Tied to Apellis’ Geographic Atrophy Med Syfovre

Apellis Pharmaceuticals’ Syfovre, after achieving the first FDA approval for advanced eye disease geographic atrophy, has been associated with rare but severe side effects, according to the American Society of Retinal Specialists (ASRS).The group issued a letter to doctors Saturday flagging cases of eye inflammation and six reports of occlusive retinal vasculitis in patients who took the drug, BioPharma Dive reported. The condition is a type of inflammation that blocks blood flow to the retina and could potentially cause blindness.ASRS didn’t tie the safety issues to a specific batch of product but noted that the side effects began one to two weeks after a patient’s first Syfovre injection. The organization urged vigilance and close follow-up after administration, according to the news outlet. The news caused Apellis’ stock price to sink nearly 32% to $52.62 by Monday afternoon. The company puts the Syfovre-associated retinal vasculitis rates at 0.01% per ...

Fighting AMR with a Value and Subscription Model

Antimicrobial resistance (AMR) happens when microbes such as bacteria, viruses and fungi change over time and stop responding to medicine. Their failure to respond makes it harder to treat infections, potentially resulting in spread, serious illness or death. In today’s AMR drug discovery sector, pharmaceutical companies find it challenging to profit from new innovative drugs because, rightfully, hospitals reserve these drugs for only advanced cases. As a result, the current approach reduces the financial incentive to make these drugs, contributing to global concern about AMR infections and their impact. Legal guidance on AMR returns On 27 April, the Pasteur Act, which deals with AMR and is sold as a bipartisan legislation to combat superbugs, was reintroduced into the US Senate. A core focus, this time around, is to jumpstart antibiotic development with a new payment model for novel treatments alongside improving how existing antibiotics are prescribed. ...

Acumen Shares Positive Results for Investigational Alzheimer’s Disease Therapy at AAIC

Acumen Pharmaceuticals has presented positive topline results from an early-stage study of its investigational Alzheimer’s disease therapy at this year’s Alzheimer’s Association International Conference (AAIC). The drug, ACU193, works by targeting and binding to amyloid beta oligomers, a toxic and soluble version of the amyloid protein that forms brain plaques associated with Alzheimer’s disease. Results from the phase 1 randomised, placebo-controlled INTERCEPT-AD study of 62 patients with early Alzheimer’s disease showed the candidate was generally well tolerated throughout both single-ascending and multiple-ascending dose cohorts. Patients who received higher doses of the drug also showed a reduction in amyloid plaque after six to 12 weeks, the company said, adding that the study suggests the drug can be given as a monthly intravenous infusion. Commenting on the positive results, Acumen’s president and chief executive officer, Daniel O’Connell, said: “ACU193’s observed dose-related central target engagement, rapid reduction of ...

Gilead’s COVID-19 Treatment Approved by FDA for Patients with Severe Renal Impairment

Gilead Sciences has announced that its COVID-19 treatment, Veklury (remdesivir), has been approved by the US Food and Drug Administration (FDA) to treat patients with severe renal impairment, including those on dialysis. The drug is already approved in the US to treat COVID-19 in adults and paediatric patients who are hospitalised or have mild-to-moderate COVID-19 and are at high risk for progression to severe illness. However, its use has previously been limited among patients with severe renal impairment due to insufficient data. The FDA’s latest decision makes Veklury the first and only approved antiviral COVID-19 treatment that can be used across all stages of renal disease. Gilead’s supplemental new drug application was supported by positive results from a phase 1 study as well as data from the phase 3 REDPINE trial that demonstrated the efficacy and safety profile of Veklury among patients with moderately and severely ...

Portable, Low-Cost Tech Tracks Uterine Contractions

Chakrabartty’s lab created a battery-powered portable instrumentation that connects with a stretchy patch that places electrodes around the wearer’s abdomen. The electrodes detect both maternal heartbeat and EMG signals, which correspond to uterine contractions. Chuan Wang created flexible electrodes that Chakrabartty’s group used to build the device. Credit: Washington University in St. Louis Keeping track of pregnancy requires a dizzying array of gargantuan and expensive machines. An MRI machine is the size of a room and can cost up to $1 million. But the care such equipment provides is a critical part of prenatal care, especially for dealing with complications like preterm birth. To get this care, pregnant people frequently need to visit a hospital, a significant burden for underserved and disadvantaged communities. In a paper published May 19 in early access online in IEEE Transactions on Biomedical Circuits and Systems, a collaboration of researchers at Washington University St. ...

Eli Lilly Strengthens the Case for Going Early in Alzheimer’s Treatment

Alzheimer’s disease patients in the earliest stages of their disease benefited the most from Eli Lilly drug donanemab, which is expected to receive an FDA decision by the end of 2023. Full results from the drug’s pivotal study were presented during the during the Alzheimer’s Association International Conference. Eli Lilly has submitted its Alzheimer’s disease drug candidate for FDA review, and the pharmaceutical giant is now revealing a more complete look at the clinical data supporting an application that could make the therapy the second anti-amyloid antibody to win full regulatory approval. Lilly had previously said its drug, donanemab, led to a 35% slowing in the decline associated with Alzheimer’s. Those results were for patients with intermediate levels of tau, another protein that’s also characteristic of Alzheimer’s progression. In patients with low-to medium-levels of tau, representing an earlier stage of the disease, treatment with the Lilly drug led to a ...

Citius Seeks Approval for I/ONTAK Ahead of Spin-Off Plans

Citius Pharmaceuticals is planning to spin out its immune asset I/ONTAK into a separate publicly-traded entity, pending the FDA’s verdict on the candidate, due July 28. I/ONTAK, which Citius is proposing as a treatment for T-cell lymphoma, is a reformulation of Eisai’s Ontak (denileukin diftitox), which won initial approval in 1999 for the same indication. Citius’ candidate is a recombinant fusion protein that combines a diphtheria toxin with the interleukin-2 protein. It works by specifically binding to IL-2 receptors to precisely deliver its toxic payload, thereby preventing protein synthesis in malignant T cells. I/ONTAK also targets the immunosuppressive regulatory T cells, which in turn allows the body to produce a stronger immune response against the cancer. The therapeutic fusion protein is approved in Japan, where it is marketed under the brand name Lymphir. The FDA accepted Citius’ Biologics License Application for I/ONTAK in December 2022 and initially gave it a target action ...

Verrica Hopes Third Time’s the Charm for Viral Skin Disease Treatment

On July 23, the FDA is set to make a decision on Verrica Pharmaceuticals’ investigational topical treatment VP-102 (cantharidin 0.7% topical solution), which is being proposed to treat molluscum contagiosum. If approved, VP-102 would become the first authorized treatment for this viral skin infection. Affecting some six million patients in the U.S. —primarily children—molluscum contagiosum is a highly contagious viral skin disease characterized by distinctive, raised pinkish lesions that are itchy and sometimes painful. In some cases, these bumps can also lead to inflammation and increase the risk of infection. Molluscum contagiosum is caused by a pox virus that is easily transmissible via fomites or direct skin-to-skin contact. Though usually mild or benign, the disease can persist for several months or years when left untreated. VP-102 is a drug-device combination containing a 0.7% formulation of cantharidin delivered through a single-use applicator that ensures precise dosing. Verrica ...
