Ofatumumab

The first dose of ofatumumab administered on Day 1 will be 300 mg to minimize infusion reactions. If the initial 300 mg dose of ofatumumab is well-tolerated, without occurrence of any infusion-associated AEs of \>= grade 3, on Day 3 ofatumumab will increase to 1000 mg IV. If the Day 3 dose was well-tolerated (i.e., no infusion-associated AE \>= grade 3), on Day 8 the ofatumumab dose will escalate to 2000 mg IV. To achieve the primary endpoint for this study, 20% of the 2000 mg ofatumumab dose only will be administered over the first 30 minutes and if tolerated the remaining 80% of the dose will be infused over the remaining 1.5/hours of each treatment. Ofatumumab doses, weeks 3-8, will remain at 2000 mg IV with no further dose escalations. If the Day 8 (Week 2) dose is tolerated all subsequent doses may be infused in the same manner.

This is a Phase II, single-arm study of ofatumumab investigating the safety of an accelerated infusion schedule of ofatumumab in patients who have received at least one prior therapy for CLL. The primary endpoint is to evaluate the number of subjects able to complete infusion number 3 (2000 mg) within 15 minutes of the planned time.

The purpose of this study is to develop an accelerated infusion regimen that allows ofatumumab to be delivered in a safe manner while minimizing the time required administering the treatment. We hypothesize there will be fewer infusion-related reactions using the proposed dose-dense approach the first week before accelerating the rate of infusion.

Rapid Infusion of Ofatumumab in Patients With Previously Treated Chronic Lymphocytic Leukemia

Rapid Infusion of Ofatumumab in Patients With Previously Treated Chronic Lymphocytic Leukemia, a Phase II Trial

Defined as percent of patients who are able to complete the Day 8 (2000 mg IV Ofatumumab) infusion within 15 minutes of the planned 2-hour treatment goal.

Defined as the actual mean infusion times, in minutes, for patients to complete a schedule of 3 infusions with the goal of completing Infusion #3 within 15 minutes of the planned 2-hour treatment time.

Defined as the percent of patients having a complete or partial response (CR or PR) assessed by International Workshop on CLL Working Group (IWCLLWG) Diagnostic Criteria (Hallek et al., 2008). CR = (a) Peripheral blood lymphocytes below 4000/µl; (b) Absence of significant lymphadenopathy by physical exam or radiographic scans (c) No hepatomegaly or splenomegaly; (d) Absence of constitutional symptoms; and blood counts above specified values. PR = (a) Decreased blood lymphocytes by 50% or more from the value prior to therapy;(b) No increase in any lymph node, and no new enlarged lymph node. Progressive Disease (PD) = An increase in 50% or more in greatest determined diameter of any previous site. Stable Disease (SD) = No evidence of CR or PR and no evidence of progressive disease.

Defined as the time from first treatment until objective tumor progression or death from any cause.

Defined as the time from first treatment until death from any cause.

Patients who received at least 1 dose of protocol treatment either Infusion #1 (300 mg), Infusion #2 (1000 mg) or Infusion #3 (2000 mg) are included in the assessment.

All patients who received at least one dose of protocol treatment are included in the safety analysis.

Ofatumumab administered by intravenous (IV) infusion. The goal infusion time at Infusion #3 is 120 minutes.

* Infusion 1 (Week 1, Day 1): 300 mg IV starting at 3.6 mg/hr and doubling every 30 minutes until reaching a rate of 240 mg/hr. (Planned infusion time: 226 minutes) If tolerated, patients receive Infusion 2.
* Infusion 2 (Week 1, Day 3): 1000 mg IV starting at 50 mg/hr and doubling every 30 min until reaching a rate of 80 mg/hr. (Planned infusion time: 167 minutes) If tolerated, patients receive Infusion 3.
* Infusion 3 (Week 2, Day 1): 2000 mg IV, 20% to be given for 30 minutes and, if tolerated, the remaining 80% to be infused over the next 90 minutes. (Planned infusion time: 120 minutes)
* Weeks 3-8: If 2000mg dose is tolerated, subsequent infusions will be given weekly in the same manner. Assessments will be done at week 12; responding patients can continue receiving the 2000 mg IV infusion monthly for 4 months up to week 28.

Ofatumumab Accelerated Infusion

Ofatumumab administered by intravenous (IV) infusion. The goal is to complete infusion #3 within 120 minutes (+/- 15 minutes).

* Infusion 1 (Week 1, Day 1): 300 mg IV starting at 3.6 mg/hr and doubling every 30 minutes until reaching a rate of 240 mg/hr. (Planned infusion time: 226 minutes) If tolerated, patients receive Infusion 2.
* Infusion 2 (Week 1, Day 3): 1000 mg IV starting at 50 mg/hr and doubling every 30 min until reaching a rate of 80 mg/hr. (Planned infusion time: 167 minutes) If tolerated, patients receive Infusion 3.
* Infusion 3 (Week 2, Day 1): 2000 mg IV, 20% to be given for 30 minutes and, if tolerated, the remaining 80% to be infused over the next 90 minutes. (Planned infusion time: 120 minutes)
* Weeks 3-8: If 2000mg dose is tolerated, subsequent infusions will be given weekly in the same manner. Assessments will be done at week 12; responding patients can continue receiving the 2000 mg IV infusion monthly for 4 months up to week 28.
