Open-Label, Multicenter, Phase 1b Study Of Daratumumab In Combination With Pomalidomide And Dexamethasone In Patients With At Least 2 Lines Of Prior Therapy And Relapsed Or Relapsed And Refractory Multiple Myeloma

Introduction: Daratumumab (DARA) is a human anti-CD38 IgG1κ monoclonal antibody with remarkable safety and activity as monotherapy in heavily treated relapsed and refractory (RR) multiple myeloma (MM) (Lokhorst HM. J Clin Oncol 2014;32 Suppl:abstr 8513. Lonial S. J Clin Oncol 2015;33 Suppl:abstr LBA8512). DARA has demonstrated clinical activity in combination with lenalidomide (LEN) and dexamethasone (D) in relapsed or RR MM (Plesner T. Blood 2014;124(21):84). This ongoing 4-arm, multicenter, phase 1b study (NCT01998971) evaluated the safety and efficacy of DARA in combination with various backbone therapies and pomalidomide plus D (POM-D). Results in newly diagnosed patients treated with DARA and backbone therapies were previously reported (Mateos MV, et al. Haematologica 2015;100(s1):84).
