Saad Z. Usmani, MD: The subq [subcutaneous] formulation of daratumumab was approved by the FDA at a very opportune time back in 2020 when we were in the early phases of the COVID-19 pandemic. I think the approval came through in May of 2020. Both patients and physicians saw that as a blessing because the time that the patients were committed to being in the health care setting, being in the infusion center, was rapidly reduced from many hours to 5 minutes or less for the administration of the formulation. Our center had completely gone from IV [intravenous] to subq formulation that year after the regulatory approval came through. It was a good experience for the patients. We did not see any changes in efficacy, not that we expected it, based on the COLUMBA trial and other studies that have incorporated subq daratumumab in all the regimens that were previously approved with the IV formulation. That transition was quite smooth, and it made a lot of patients very happy that we were reducing the time to administer that drug.
