Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 34
Healthy volunteers: no

Brief summary:
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.

Detailed description:
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.

Arms:
arm 1: Rapid Infusion of Ofatumumab

Interventions: intervention 1: Ofatumumab
Intervention descriptions: intervention 1: 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.
