High school senior, trumpet player, and actual Oxbryta patient
Oxbryta was studied in a trial in which 90 patients received Oxbryta (daily dosage of 1500 mg) and 92 patients received a placebo (sugar pill).*
The trial included patients ages 12 and up who took the medication daily for 24 weeks. Oxbryta trials are currently ongoing to watch the progress of patients taking Oxbryta for longer than 24 weeks.*Patients who were already taking hydroxyurea at the start of the clinical trial continued to do so for the entire 24-week trial period.
One of the goals of the clinical trial was to find out if treatment with Oxbryta helped hemoglobin levels rise more than 1 gram per deciliter from where they were before taking Oxbryta.
During the clinical trial, 5 out of 10 patients (51.1%) taking Oxbryta reached this goal vs 6.5% of the patients taking placebo.
On average, hemoglobin levels increased by 1.14 grams per deciliter for patients on Oxbryta vs decreasing by 0.08 grams per deciliter for the placebo group.

Decreases in hemolysis are good, and mean that fewer red blood cells are breaking down. Hemolysis can be measured in different ways including:[bil-uh-roo-bin] levels and [ri-tik-uh-luh-site] count.
After taking Oxbryta, patients had lower bilirubin levels than before they started treatment. On average, their bilirubin levels fell by 29.08% vs only 3.16% for the placebo group.
On average, the reticulocyte count for patients taking Oxbryta fell by 19.93% vs the patients on placebo, whose reticulocyte count increased by 4.54%.
