What the trial was testing
The CONTINUUM enrolled 317 patients with leukemia. The study was sponsored by Celgene and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Patients on lenalidomide went 34 months without their cancer progressing versus 9 months on placebo.

These findings — that lenalidomide delayed progression nearly 4 times longer than placebo — were published in the The Lancet. Haematology and represent the headline result of the study.
Researchers tracked outcomes across 317 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with leukemia, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This was a large-scale study, but lenalidomide for CLL maintenance is not widely FDA-approved for this use. The study showed it delayed cancer progression but didn't help patients live longer overall. Talk to your doctor about whether this approach makes sense for you, especially if newer targeted therapies aren't available to you.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

ELVN-001 for the Treatment of Chronic Myeloid Leukemia With and Without T315I Mutation in Japanese Participants
The purpose of this study is to evaluate the safety, tolerability and determine the recommended dose for further clinical evaluation of ELVN-001 in Japanese patients with chronic phase chronic myeloid leukemia with and without T315I mutations in patients who has failed, or the patient is intolerant to, or not a candidate for, at least 2 prior TKIs.
