New gene therapy may not be ‘one-and-done’ homerun

BioMarin Pharmaceutical reported this week that the effects of its new gene therapy may diminish over time.

In conclusion, we show here that sEVs are responsible for mediating paracrine senescence and speculate that they could be involved in inducing bystander senescence during therapy-induced senescence or aging. In fact, when compared to soluble factors, sEVs have different biophysical and biochemical properties as they have a longer lifespan than do soluble factors and they are more resistant to protease degradation. The idea that blocking sEV secretion could be a potential therapeutic approach to alleviate senescence "spreading" during chemotherapy-induced senescence or in aging tissues presents itself as a very at...

Historically, the diagnostic process was slow and patient prognosis regarded as poor because curative treatment was only available for very few leukodystrophies in early stages of the disease. Whole-exome sequencing has both greatly increased the number of known leukodystrophies and improved diagnosis. Whether MRI keeps its central place in diagnosis and what t...

Gene therapy has been employed in the human brain for a number of disorders in clinical trials and may serve as an avenue for the treatment of Parkinson's disease (PD). Several gene therapy treatment strategies have been developed and evaluated in patients with PD. Three main strategies have been used-enhancement of dopamine synthesis, expression of trophic factors, and neuromodulation. Typically, genes are delivered via viral vectors and expressed within neurons in PD-relevant areas of the brain such as the striatum.

Conclusion: Based on our presented case and a vast amount of literature there is circumstantial evidence that TCR gene therapy for melanoma targets the perivascular macrophage-like melanocytes in the stria vascularis, resulting in SNHL. We suggest that SNHL after TCR gene therapy may be caused by a disruption of the blood–labyrinth–barrier and the endolymphatic potential and/or a sterile inflammation of the stria vascularis. In severe cases like our subject, we posit that endolymphatic hydrops or hair cell loss may cause irreversible and asymmetrical deafness. Steroid prophylaxis via transtympanic application is debatable.
