In an editorial accompanying the study , Cindy Leissinger, MD, of Tulane University School of Medicine in New Orleans, said a major advantage of efanesoctocog alfa "is its value as a true factor VIII replacement that can be used to treat acute bleeding and can be measured by standard laboratory assays to allow for monitoring and dose adjustments when needed.

Forkhead Box Protein E3 (FOXE3, forkhead-related protein FKHL12, forkhead-related transcription factor 8) is a forkhead/winged helix transcription factor, which is expressed in the developing lens from the start of lens placode induction and becomes restricted to the anterior proliferating cells when lens fiber differentiation begins.

It carries significant short-term and long-term adverse health outcomes for both mother and offspring, which reinforces the significance of understanding risk factors, in particular modifiable factors, for GDM and of preventing the condition. (springer.com)

Copper is a required cofactor for factor VIII and copper deficiency is known to increase the activity of factor VIII. (wikipedia.org)
The factor VIII activity levels reflect measurements up to 61 weeks, the extent of follow-up for the longest-treated patient in the cohort. (businesswire.com)
Of note, von Drygalski and team said that once-weekly prophylaxis with efanesoctocog alfa provided mean factor VIII activity of more than 40 IU/dL for approximately 4 days after administration and of 15 IU/dL at day 7. (medpagetoday.com)

The sequences of these clones revealed an intronless gene conding for 380 amino acids, with 85% identity the predicted human sequence. (wustl.edu)

She also pointed out that while trials of factor VIII gene therapies also show prolonged production of factor VIII, the latest results suggest that factor VIII production in most patients gradually declines over a few years to trough levels demonstrated with weekly efanesoctocog alfa.

A study by Ladikou et al indicated that patients with coronavirus disease 2019 (COVID-19) commonly have high levels of vWF and factor VIIIc, which may play a role in the hypercoagulable state and increased venous thromboembolism (VTE) rate encountered in COVID-19. (medscape.com)
Gene therapy, on the other hand, offers a new approach with the potential to provide a one-time treatment that would enable patients to produce the missing factor on their own," said Bettina M. Cockroft, M.D., M.B.A., Chief Medical Officer of Sangamo. (businesswire.com)
The team found key differences in 16 genes in the ICU patients when compared with the DNA of the other groups. (ed.ac.uk)
The genetic analysis of nearly 56,000 samples from people in Britain showed differences in 23 genes in COVID-19 patients who became critically ill, when compared with the DNA of other groups included in the study, including 16 differences that had not been previously identified. (cbc.ca)
In addition, four patients who have been followed the longest had a mean factor VIII level of 146% at their 20 week visit. (uclb.com)
Two patients with factor VIII levels above 200% had no unexpected events or need for medical intervention. (uclb.com)
For the seven patients at the high dose, the median annualized bleeding rate measured from day of gene transfer to data cut of observation period fell to 5 from 20. (uclb.com)
It was hoped the gene therapy would enable patients to forego or reduce those infusions. (equities.com)
In many patients with a deficiency of VWF, low level of factor VIII has been found. (medscape.com)

BACKGROUND AND AIMS: It is reported that patients with obesity are more frequently hospitalized for COVID-19, and evidence exists that obesity is a risk factor, regardless of other comorbidities. (bvsalud.org)

Administration of gene therapy viruses into skeletal muscle, where distal terminals of motor and sensory neurons reside, has been shown to result in extensive transduction of cells within the spinal cord, brainstem, and sensory ganglia. (frontiersin.org)

Because it's a single gene disorder there's the tantalising prospect that the bad gene can be easily replaced. (brighthub.com)
