Typical dosage for Casgevy
Casgevy is usually given at a qualified treatment center or in a hospital. Your hematologist will choose your dose based on your weight. The treatment process takes several stages:
- Cell collection and manufacturing: Your stem cells are collected and sent to a lab where they're made into Casgevy that's specific for you. This part of the process can take up to 6 months.
- Conditioning: You'll receive chemotherapy to prepare your body to receive Casgevy.
- Infusion: Your care team will infuse Casgevy through a vein as a one-time infusion.
After treatment, you'll stay in the hospital for about 4 to 6 weeks so your care team can monitor your recovery and watch for side effects.
