A trial looking at ofatumumab for mantle cell lymphoma

The trial team found that ofatumumab was not likely to be a useful treatment for mantle cell lymphoma.

To begin with, this trial recruited 12 people with mantle cell lymphoma that had come back after treatment. They all had ofatumumab through a drip into a vein, once a week for up to 5 weeks.

When the research team looked at how well the treatment had worked, they found that the lymphoma had

• Got smaller in 1 person
• Stayed the same in 6 people
• Continued to grow in 5 people

The research team had hoped to recruit 34 people for this trial. But when they looked at the results of these first 12 people, they decided not to carry on recruiting.

The most common side effect was extreme tiredness (fatigue) for a couple of days after each dose of treatment. This affected 9 out of the 12 people (75%) in the trial.

The research team concluded that the dose of ofatumumab they used in this trial was not a useful treatment for mantle cell lymphoma.
