| NCT00774202 | Higher Dose of Rituxan Versus Standard Doses of Rituxan With Cyclophosphamide, Vincristine, and Prednisone in Subjects With Chronic ITP | PHASE2 | COMPLETED | 17 | — | — | Nov 1, 2003 | Feb 1, 2008 | Jan 9, 2019 | 1 | United States |
Outcome measure was determined by comparing the study participants' historical responses to their initial treatment of rituximab at standard dose/regimen without "enhancement" (based on duration of response and type of response) to the participants response to their study treatment responses. Thus each patient was his or her own control although all study treatments included standard dose rituximab treatments (one at double the dose and one with additional treatments).
| Arm | Type | Description |
|---|---|---|
| Rituximab, Cyclophosphamide, Vincristine, Prednisone | ACTIVE_COMPARATOR | 'Standard Dose of Rituximab administered with C, V, P (CVP)' Interventions: Rituximab will be administered as an IV infusion at the standard dose of 375 mg/m2 for 4 doses at standard rates and use of premedication. The schedule will be to give the first rituximab infusion 5 days (± 3 days) prior to first administration of CVP, and the following 3 infusions will be given on the same day as the 3 cycles of C, V, P. On those days, the IV Cyclophosphamide and Vincristine will be given first so that the administration of fluids with the rituximab can be used as post-cyclophosphamide hydration, Cyclophosphamide dosing will be 750mg/m2 (maximum 2000mg), vincristine 1.4 mg/m2 (up to 1.6 mg), prednisone 100mg po daily for 5 days. |
| Higher Dose of Rituximab | ACTIVE_COMPARATOR | In this arm, Rituximab will be administered at a dose of 750 mg/m2 once a week x 4 consecutive weeks (4 infusions in total). We will perform EKG monitor tracings before, during and after Rituxan infusions. This will be a single-lead tracing that will allow us to look at the Q-T interval. |

| Rituxan, Cyclophosphamide, Vincristine, Prednisone | DRUG | 'Rituximab, Cyclophosphamide, Vincristine, Prednisone interventions are as follows: Rituximab will be administered as an IV infusion at the standard dose of 375 mg/m2 for 4 doses. However, the schedule of the infusions will be different than the usual one: Rather than administrating the 4 doses once weekly, the first infusion will be given 5 days (± 3 days) prior to the first infusions of C and V and oral P, and the following 3 rituximab infusions will be given on the same day as the 3 cycles of C, V, and P. |
| Higher Dose of Rituximab | DRUG | rituximab 750mg/m2 (twice the standard dose of 375mg/m2) will be given weekly for 4 weeks. Premedication and infusion rate escalation will be exactly the same as for standard dose rituximab. The additional dose will thus run at 400ml/hr. |
Inclusion Criteria: Patients will be eligible to participate in the study if they: * Have chronic ITP19 (\> 6 months duration) * Have received Rituximab a minimum of 3 months prior to entry * Have received no more than 2 courses of Rituximab at standard dose separated by a minimum of 12 weeks * Ha...
