What to expect from Crispr technology in gene therapy?

2024-02-13 09:00:04

On December 15, 2023, the European Medicines Agency (EMA) approved the first treatment using Crispr genome modification technology. This medical advance aims to cut out a DNA sequence and replace it with another, using a pair of “molecular scissors”. The first treatment using this method should be to relieve patients suffering from sickle cell anemia or beta thalassemia, two genetic hemoglobin diseases.

How does this new medical approach work? What perspectives does CRISPR technology open up for medicine? Finally, is gene therapy safe for humans?
