I've been on daratumumab maintenace for 2 years after reaching CR. I receive dara every 8 weeks and just recently had a bone marrow biopsy which showed no plasma cells in the marrow but my clonal cells have increased from 800 to 5,000 per million. I will be asking my oncologist to increase dara to every 4 weeks. Has anyone had a similar experience of increasing dara during the maintenance phase and seeing improved results? The other option will be to add on pomalyst but I'm hoping to stick with dara only for a while.
