摘要

Combination therapy with daratumumab, lenalidomide, and dexamethasone (D-Rd) has greatly improved outcomes for transplant-ineligible newly diagnosed multiple myeloma (TIE-NDMM). Effective management of herpes zoster (HZ) and other infections is critical to maximize therapeutic benefit and to maintain treatment continuity. However, antiviral prophylaxis for HZ in TIE-NDMM patients receiving D-Rd has unclear efficacy, and is currently not covered by health insurance in Japan. In this study, we retrospectively analyzed the incidence of HZ in 40 TIE-NDMM patients treated with D-Rd. Nine patients (22.5%) developed HZ at a median period of 10.7 months (range, 0.4–34.2 months) after starting D-Rd. The cumulative HZ incidence at 12, 24, and 36 months was 13.3%, 19.5%, and 28.6%, respectively. Development of HZ was not associated with patient characteristics, disease characteristics, or hematologic response. Our data indicate a high incidence of HZ in TIE-NDMM patients receiving D-Rd, and we anticipate that Japanese health insurance should soon cover prophylactic treatment of HZ in D-Rd.
