Can a cancer drug stop myeloma before it starts?

NCT ID NCT03236428

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial is testing the drug daratumumab in 42 people with high-risk MGUS or low-risk smoldering multiple myeloma—early, pre-cancerous conditions that can lead to multiple myeloma. The goal is to see if daratumumab can produce a deep response (very good partial response or better) after 20 cycles of treatment. Participants receive the drug intravenously, and the study tracks how well it controls the abnormal plasma cells.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Daratumumab (Darzalex)

What this could lead to

If successful, this could show that daratumumab can significantly reduce or eliminate abnormal plasma cells, potentially delaying or preventing progression to active multiple myeloma.

What could go wrong

This is a small, early-phase study (42 participants) without a control group, so results may not be definitive. Daratumumab can cause infusion reactions and increase infection risk.
