RYONCIL is a special medicine made from living cells. This is also known as cell therapy. It's given through an IV. This usually happens twice a week for 4 weeks. That's 8 infusions, total. It's not a pill. No donor matching is needed.
The care team will prescribe the dose of RYONCIL that's right for your child. This will be guided by his or her weight. Each infusion will be spaced at least 3 days apart. This gives your child's body the chance to benefit from treatment.
Your care team can help create a treatment plan for a weekly routine that works with your family's schedule.
Know what to expect before, during, and after treament
Talk with your child’s care team about what to expect with RYONCIL.
Your child will be watched during treatment. About 30 minutes to an hour before each infusion, your child will get medicines to help lower the chance of an allergic reaction. After each infusion, the care team will check for fever, chills, or other reactions. Then your child can go back to his or her regular routine.
After about 28 days, the care team will decide if more doses are needed.

If all signs of steroid-refractory acute GvHD have gone away: no more infusions are needed.
If steroid-refractory acute GvHD comes back after fully going away: the full RYONCIL routine may be repeated. That would be 2 infusions per week for 4 more weeks.
If some signs got better while others stayed the same: 1 more infusion per week may be given for another 4 weeks. This would be 4 more infusions.
If there is no response, talk with your child’s healthcare team about other options.
