Study information

Scientific title

A Randomised Investigation of Alternative Ofatumumab containing regimens in less fit patients with chronic lymphoid leukemia (CLL)



Study hypothesis

This is a randomised, controlled, phase III trial comparing ofatumumab and chlorambucil (OChl) with ofatumumab and bendamustine (OB) in patients with chronic lymphocytic leukaemia (CLL) who are considered not fit enough to receive more intensive combination chemotherapy.

The primary purpose of the trial is to establish if OB is more effective at prolonging the worsening of the disease than OChl.

Ethics approval

NRES Committee North West - Haydock, First MREC approval date 14/09/2011, ref: 11/NW/0548

Topic: National Cancer Research Network; Subtopic: Haematological Oncology; Disease: Leukaemia (chronic)


670 patients are to be enrolled in total (335 per treatment arm) from approximately 100 centres throughout the United Kingdom.

Patients will receive between 3 12 cycles of treatment depending on which treatment arm they are allocated to and how well they respond to the treatment. The schedule of treatment is as follows:
Arm 1: OChl repeated every 28 days for up to 12 cycles depending on clinical response after cycles 3, 6 and 9.
Arm 2: OB repeated every 28 days for up to 6 cycles depending on clinical response after cycle 3.

All patients will be followed up for a minimum of 2 years from trial entry. All laboratory and physical assessments are routine for CLL but additional scientific tests may be performed when specific consent has been given.

Ofatumumab and Bendamustine, Ofatumumab cycle 1: 300mg iv day 1, 1000mg iv day 8
cycle 2 onwards: 1000mg iv day 1
Bendamustine: 70mg/m2 iv days 1 and 2
Cycles to be repeated every 28 days, up to 6 cycles depending on clinical response after cycle 3;
Ofatumumab and Chlorambucil, Ofatumumab cycle 1: 300mg IV day, 100mg iv day 8
cycle 2 onwards: 1000mg iv day 1
Chlorambucil: 10mg/m2 po days 1 to 7
Cycles to be repeated every 28 days, up to 12 cycles depending on clinical response after cycles 3, 6 & 9; Follow Up Length: 24 month(s)
