Researcher discusses mechanism behind a birth defect affecting brain size

Nonsense-mediated RNA decay, or NMD, is an evolutionarily conserved molecular mechanism in which potentially defective messenger RNAs, or mRNAs (genetic material that instructs the body on how to make proteins), are degraded. Disruption of the NMD pathway can lead to neurological disorders, immune diseases, cancers, and other pathologies. Mutations in human NMD regulators are seen in neurodevelopmental disorders, including autism and intellectual disability.

Boehringer Ingelheim gets USFDA nod for high-concentration, citrate-free formulation of Cyltezo to treat multiple chronic inflammatory diseases

Ridgefield: Boehringer Ingelheim has announced that the U.S. Food and Drug Administration (FDA) has approved the high-concentration, citrate-free formulation of Cyltezo (adalimumab-adbm), the company’s interchangeable* biosimilar to Humira (adalimumab), to treat multiple chronic inflammatory diseases.

“With this FDA approval, we are now able to offer both high- and low-concentration, citrate-free formulations of Cyltezo, further expanding treatment access for patients living with certain chronic inflammatory diseases,” said Stephen Pagnotta, Executive Director and Biosimilar Commercial Lead at Boehringer Ingelheim. “Many patients are treated with high-concentration adalimumab formulations, and we are excited to add this new option to our approved citrate-free Cyltezo and Adalimumab-adbm offerings.”

The high-concentration formulation (100 mg/mL), which is now available as a pre-filled syringe or pre-filled autoinjector, is priced at a 5% discount to Humira under the brand name Cyltezo and at an 81% discount to Humira as the unbranded product Adalimumab-adbm. The low-concentration (50 mg/mL), citrate-free formulation of Cyltezo has been commercially available since July 2023.

“The availability of a high-concentration and citrate-free Cyltezo is welcome news for people living with certain chronic inflammatory conditions, such as Crohn’s disease and ulcerative colitis, which affect nearly 1 in 100 Americans,” said Michael Osso, President & CEO of the Crohn’s & Colitis Foundation. “The flexibility of having multiple biosimilar formulations to choose from is important to support broader patient access to biologic medicines.”

“This FDA approval is another step forward for people with chronic and often debilitating diseases such as rheumatoid and psoriatic arthritis,” said Steven Taylor, President & CEO of the Arthritis Foundation. “We stand united with our patients and healthcare providers in the effort to accelerate the adoption of biosimilars, which benefit patients as well as the larger healthcare ecosystem.”

“Biologics and biosimilars are a crucial treatment option for many living with psoriatic arthritis or psoriasis,” said Leah M. Howard, J.D., President and CEO of the National Psoriasis Foundation. “We welcome the introduction of this additional formulation to expand the array of options available to our community.”

The FDA approval is based, in part, on data from clinical trial VOLTAIRE-HCLF, a Phase I clinical trial comparing the bioavailability of high-concentration and low-concentration formulations of adalimumab-adbm.

Tamil Nadu Doctors’ Association demands strict action against Misleading Ads by Patanjali

Chennai: The medical community in the state is calling for stringent action
against misleading advertisements from Baba Ramdev’s Patanjali. At a recent state
conference in Trichy, healthcare professionals emphasized the need to regulate
unscientific medical information. 

Dr G. R. Ravindranath, general secretary of the Doctor’s Association for Social Equality criticized
Ramdev for falsely claiming that Coronil could cure and prevent COVID-19. Dr Ravindranath accused Ramdev of publishing false advertisements and deceiving
the public with unverified medical claims.

Representatives of the Doctors Association for Social Equality argued
that Ramdev’s promotion of Ayurvedic medicines contradicts modern scientific
principles. They demanded strict measures against Ramdev for misleading people
under the pretence of promoting Ayurveda. 

Citing Patanjali products as an example, the doctors advocate for a ban
on advertising pharmaceutical products without scientific evidence to support
their use. They insist that policies must be implemented to combat fake
science, superstitions, and anti-scientific notions in medicine, as these can
negatively affect individuals’ health and well-being across the country, reports DT Next

The association stated, “We demand that the Union Government should apologize to act in favor of advertising such medicines. There should be stringent action against promoting medicines that can be harmful for the patients. The government needs to come up with policies on regulating mixopathy, Vedic medicine, traditional medicine, spiritual therapies and others, being practiced for treating diseases.”

Recently, a report in Reuters stated that a state regulator in India has suspended the manufacturing licenses of 14 products produced by pharmaceutical companies associated with the country’s renowned yoga guru. The suspension comes in response to the repeated dissemination of misleading advertisements regarding the efficacy of the products, as indicated by a government order. 

The Supreme Court of India has in recent weeks repeatedly criticized Ramdev for not complying with its directives in an ongoing lawsuit to stop misleading advertisements of some of his traditional ayurvedic medicines. Though the company has already apologized for the unscientific advertisement, the Supreme Court asked whether the apology published by Patanjali Ayurved was as big as the advertisements.

Meta-analysis reveals contrasting effects of AF ablation in heart failure: Reduced vs. preserved ejection fraction

Canada: In the realm of cardiovascular health, the coexistence of atrial fibrillation (AF) and heart failure (HF) presents a complex clinical challenge, necessitating nuanced treatment approaches. A recent systematic review and meta-analysis have shed light on the differential impact of atrial fibrillation ablation in patients with heart failure, stratified by ejection fraction status.

The study, published in JAMA Cardiology found that patients with heart failure with preserved ejection fraction (HFpEF) did not derive the same benefit from catheter ablation as patients with heart failure with reduced ejection fraction (HFrEF).

“The systematic review and meta-analysis of 12 randomized clinical trials (RCTs) comprising 2465 participants with HF, we found catheter ablation of AF compared with conventional medical therapies was tied to a reduced risk of HF events in patients with reduced ejection fraction, while no benefit was observed in patients with preserved ejection fraction,” the researchers reported.

Catheter ablation is associated with reduced heart failure hospitalization and death in select patients with atrial fibrillation (AF) and HFrEF. However, the benefit in patients with HFpEF is uncertain. Therefore, Alireza Oraii, Population Health Research Institute, Hamilton, Ontario, Canada, and colleagues aimed to investigate whether catheter ablation for AF is associated with reduced HF-related outcomes according to HF phenotype.

For this purpose, the researchers conducted a systematic search of online databases among studies published from inception to 2023.

The study included parallel-group RCTs comparing catheter ablation with conventional rate or rhythm control therapies in patients with HF, New York Heart Association (NYHA) functional class II or greater, and a history of paroxysmal or persistent AF. Pairs of independent reviewers screened 7531 titles and abstracts, of which the selection criteria were met by 12 RCTs and 4 substudies.

Data were abstracted in duplicate using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines.

The primary outcome was heart failure events, defined as HF hospitalization, clinically significant HF worsening, or unscheduled visits to a clinician for treatment intensification. Secondary outcomes were cardiovascular and all-cause mortality.

Following were the study’s key findings:

  • 12 RCTs with 2465 participants (mean age, 65.3 years; 26.7%) were included; there were 1552 participants with HFrEF and 913 participants with HFpEF.
  • Compared with conventional rate or rhythm control, catheter ablation was associated with reduced risk of HF events in HFrEF (risk ratio [RR], 0.59), while there was no benefit in patients with HFpEF (RR, 0.93).
  • Catheter ablation was associated with a reduced risk of cardiovascular death compared with conventional therapies in HFrEF (RR, 0.49) but a differential association was not detected in HFpEF (RR, 0.91).
  • No difference in the association of catheter ablation with all-cause mortality was found between HFrEF (RR versus conventional therapies, 0.63) and HFpEF (RR versus conventional therapies, 0.95) groups.

In conclusion, the study found that catheter ablation for AF was tied to a reduced risk of HF events in patients with HFrEF but had limited or no benefit in HFpEF.

“Results from ongoing trials may further elucidate the role of catheter ablation for atrial fibrillation in HFpEF,” the researchers wrote.
