How long does Rituxan last for ITP?
Rituximab is a chimeric monoclonal antibody targeting a B-cell antigen (CD20) that has been used widely as a second line therapy for ITP with a promising response rate approaching 60% in some studies. A response is usually seen between week one to eight of therapy and could last for five years in some patients.
How long does it take Rituxan to raise platelets?
Three different patterns of response can be distinguished: a first group of patients respond rapidly, within the first month; in the second group, the platelet count starts increasing after 3-4 weeks, and a CR is achieved within 8 weeks after treatment; in the third group of patients, the platelet count increases very …
Can Rituxan be used to treat ITP?
In recent years, rituximab, (17, 18) has become a widely used treatment option for chronic ITP (19–25) Forty to sixty percent of chronic ITP patients achieve a partial or complete platelet response following their initial 4 infusions with standard dose rituximab.
What does rituximab do for ITP?
Goals of therapy: For patients given rituximab for ITP, the result can be an increase the number of platelets in the blood when platelets are low. By increasing the platelet count to a goal of usually 50 k/μL or higher, the risk of bruising and bleeding (both spontaneous and injury-induced) is decreased.
How is rituximab used in the treatment of ITP?
“Standard dose” rituximab results in a marked reduction of malignant and non-malignant B cells in peripheral blood and bone marrow. 49 Since the total mass of B cells is much smaller in patients with ITP than in patients with lymphoma, it was not clear whether a lower dose of rituximab or a different schedule could be equally effective.
Which is the best drug for the treatment of ITP?
We report a case of ITP that was unresponsive to multiple agents including high-dose steroid, IVIG, Rho (D) immune globulin, rituximab, cyclosporine, azathioprine, vincristine, mycophenolate mofetil, romiplostim, and eltrombopag; however, it achieved complete remission with combination treatment of cyclophosphamide and eltrombopag. 1.

How long does rituximab last as a treatment for ITP?
Likewise, not all medications used for ITP have a long-lasting effect in keeping the platelet count above 50 k/µL. When it works, rituximab can work for 1 – 2 years, but lasting responses beyond two years are rarer. The 5 year rituximab response rate is estimated at 20 – 25%.
How is Rituxan used to treat ITP thrombocytopenia?
Treatment Name: Rituximab (Rituxan®) By increasing the platelet count to a goal of usually 50 k/μL or higher, the risk of bruising and bleeding (both spontaneous and injury-induced) is decreased.
