Advances in hemophilia gene therapy bring hope for pediatric patients

In the past three years, gene therapy has reshaped what's possible in hemophilia treatment for patients 18 and older. But a key question remains: How soon will these advances reach children?

New sequencing method reveals how transposons move and shape the genome

Cornell researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind to the genome.

International experts publish guidelines on the administration of gene therapy for hereditary hearing loss

Up to 60% of congenital and early-onset hearing loss is caused by genetic mutations in an inherited gene, and gene therapy has recently emerged as a potential treatment option.

New gene-editing method can correct many disease-causing mutations in mammalian cells

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same disorder might have a different combination of mutations.

Researchers design factor IX variants for short- and long-term Hemophilia B management

After blood vessel damage, effective blood clotting is essential to halt bleeding. However, this process is inefficient in some individuals due to hereditary factors. Hemophilia B, for example, results from a deficiency in coagulation factor IX (FIX), which can lead to prolonged bleeding after injuries or surgery.

Scientists create liver organoids with functional blood vessels

Liver organoids with proper blood vessel networks have been successfully produced, as reported by researchers from Institute of Science Tokyo and Cincinnati Children's Hospital Medical Center.

New cellular entry pathway improves gene therapy outcomes

Scientists from the Centenary Institute and the University of Sydney have made a landmark discovery that could lead to safer and more effective gene therapies for a range of serious genetic disorders including Duchenne muscular dystrophy, Pompe disease and hemophilia.

New study supports non-surgical approach for select cases of acute subdural hematoma

Acute subdural hematoma (ASDH) is a common brain lesion resulting from traumatic brain injuries and is associated with high mortality and morbidity.

Gene therapy shows long-term success in hemophilia B patients

A gene transfer approach to treating the bleeding disorder hemophilia B remains safe and effective long-term, as scientists from St. Jude Children's Research Hospital and University College London today report thirteen years of follow-up data.

New gene editor evoCAST enables precise insertion of complete genes

Ask scientists what gene editing tool is most needed to advance gene therapy, and they'd probably describe a system that's now close to realization in the labs of Samuel Sternberg at Columbia University Vagelos College of Physicians and Surgeons and David Liu at the Broad Institute of MIT and Harvard.

Marstacimab approved to treat patients aged 12 years and above (weighing at least 35 kg) with hemophilia A or B

The Medicines and Healthcare products Regulatory Agency (MHRA) has approved the medicine marstacimab (Hympavzi) to prevent or reduce bleeding in patients 12 years of age and older weighing at least 35 kg with hemophilia A and B.

The role of saliva in Hemophilia A coagulation

A recent study led by MedUni Vienna provides new insights into the mechanisms of coagulation in persons with haemophilia A, the most common form of haemophilia. The research team was able to show that saliva contains special vesicles that trigger rapid coagulation of the blood of haemophilic patients. The results, which were recently published in the renowned scientific journal Blood, contribute significantly to a better understanding of the disease.

Concizumab shows promising results for hemophilia patients

For people with the bleeding disorder hemophilia, life can seem like one continuous state of alertness. If they accidentally cut their finger while chopping vegetables, they have to immediately administer the clotting factor protein that their body either lacks or does not produce enough of.

Transposons play essential role in early human development

A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found.

Study reveals life-changing impact of gene therapy for hemophilia B patients

Adults with hemophilia B saw their number of bleeding episodes drop by an average of 71 percent after a single infusion of gene therapy, according to the results of an international Phase III clinical trial published today in the New England Journal of Medicine by researchers from the University of Pennsylvania Perelman School of Medicine and a multicenter group of investigators.

Breakthrough in hemophilia A treatment: Sobi's ALTUVOCT receives EU marketing authorization

Sobi® today announced the European Commission has granted Marketing Authorization for ALTUVOCT™ (efanesoctocog alfa), for the treatment and prevention of bleeds and perioperative prophylaxis in hemophilia A. ALTUVOCT is a high-sustained factor VIII replacement therapy for all ages and any disease severity.
