CheckRareTreatment Benefit of Daratumumab for Multiple Myeloma Supported by 3-Year Follow-Up Data

Jacob Laubach, MD, at the Dana-Farber Cancer Institute provides a summary of the most recent update from the GRIFFIN trial, assessing daratumumab plus lenalidomide, bortezomib, and dexamethasone in newly diagnosed multiple myeloma patients. After 24 months of maintenance therapy or treatment discontinuation (median follow-up of 38.6 months), the rate of stringent complete response (sCR) was 66% in the D-RVd treatment arm versus 47.4% in the RVd treatment arm. At the time of data collection, median PFS had not been reached in either arm but is trending towards favoring D-RVd versus RVd. The estimated 36-month PFS rate was 88.9% for D-RVd and 81.2% for RVd.
