What the COLUMBA Trial Found — Subcutaneous Daratumumab for Multiple Myeloma

Researchers tested whether daratumumab given as a shot under the skin worked as well as the standard IV infusion in people with multiple myeloma who had tried at least three other treatments. The shot worked just as well and caused fewer side effects during administration.

What the trial was testing

The COLUMBA enrolled 522 patients with multiple myeloma. The study was sponsored by Janssen Research & Development, LLC 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

The under-the-skin shot worked just as well as the IV version, with 41% of patients responding to treatment.

These findings — that the subcutaneous shot was as effective as the IV infusion — were published in the The Lancet. Haematology and represent the headline result of the study.

Researchers tracked outcomes across 522 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 multiple myeloma, 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

Daratumumab is FDA-approved for multiple myeloma and now comes in both IV and subcutaneous forms. The subcutaneous version takes just minutes instead of hours for infusion and may cause fewer reactions during treatment. Talk to your doctor about which form might work best for 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.
