Revolutionizing Medicine: How CRISPR is Treating Blood Disorders

TLDRLearn how CRISPR, an innovative gene-editing tool, is being used to treat blood disorders like sickle cell disease. Two gene therapies, Casgevy and Lyfgenia, have been approved and are making a life-changing difference for patients. However, access and cost remain barriers for many.

Key insights

🔬CRISPR is a powerful gene editing tool that is revolutionizing medicine.

💉Casgevy is the first CRISPR-based gene therapy approved for treating sickle cell disease and β-thalassemia.

📝Lyfgenia uses an older gene editing technology called a lentiviral vector to treat sickle cell disease.

Both treatments require a complex process, including chemotherapy and stem cell transplantation.

💰The high cost of these gene therapies limits access for many patients.

Q&A

What is CRISPR?

CRISPR is a gene editing tool that allows scientists to modify specific genes by targeting and cutting DNA.

What is Casgevy?

Casgevy is a CRISPR-based gene therapy approved for treating blood disorders like sickle cell disease and β-thalassemia.

How does Lyfgenia work?

Lyfgenia uses a lentiviral vector to deliver an anti-sickling version of hemoglobin to the patient's blood stem cells.

What is the process for receiving these treatments?

The process involves regular blood transfusions, chemotherapy, stem cell transplantation, and recovery in a treatment center.

Why is access to these treatments limited?

The high cost of gene therapies like Casgevy and Lyfgenia make them inaccessible for many patients.
