Ended Therapeutic confirmatory (Phase III) Precancerous form of blood cancer in the bone marrow

A clinical study to compare the safety, effectiveness and pharmacokinetics (the way the body absorbs, distributes, and gets rid of a drug) of Daratumumab given through the subcutaneous route versus the active monitoring in patients with high risk smoldering multiple myeloma (precancerous form of blood cancer in the bone marrow)

EU CTIS ID: 2023-507143-11-00

What this study is testing

To determine whether treatment with daratumumab administered subcutaneously (SC) prolongs progression free survival (PFS) compared with active monitoring in subjects with high-risk smoldering multiple myeloma (SMM).
