Patients with relapsed and refractory multiple myeloma have poor prognosis. A recent analysis of patients with relapsed and refractory multiple myeloma who were refractory to both proteasome inhibitors and immunomodulatory drugs showed the median overall survival of 9 months only. Daratumumab is the first-in-class human monoclonal antibody against CD38 cells which was studied in phase I/II trials for treatment of these patients with relapsed refractory multiple myeloma. It showed an overall response rate of 36% and a median overall survival (OS) of 17 months in these patients...

Background Daratumumab showed promising efficacy alone and with lenalidomide and dexamethasone in a phase 1-2 study involving patients with relapsed or refractory multiple myeloma. Methods In this phase 3 trial, we randomly assigned 569 patients with multiple myeloma who had received one or more previous lines of therapy to receive lenalidomide and dexamethasone either alone (control group) or in combination with daratumumab (daratumumab group). The primary end point was progression-free survival. Results At a median follow-up of 13...

Unprecedented advances in multiple myeloma (MM) therapy during the last 15 years are predominantly based on our increasing understanding of the pathophysiologic role of the bone marrow (BM) microenvironment. Indeed, new treatment paradigms, which incorporate thalidomide, immunomodulatory drugs (IMiDs), and proteasome inhibitors, target the tumor cell as well as its BM microenvironment. Ongoing translational research aims to understand in more detail how disordered BM-niche functions contribute to MM pathogenesis and to identify additional derived targeting agents...

The advent of the immunomodulatory drugs thalido-mide, lenalidomide, and pomalidomide; the proteasome inhib-itors bortezomib, carfilzomib, and ixazomib; the histone deacet-ylase inhibitor panobinostat; and the monoclonal antibodies elotuzumab and daratumumab has led to dramatic improvements in outcomes for patients with multiple myeloma. Along with progress in nontransplant therapy have come questions regarding the continued role of high-dose melphalan (HDM) supported by autologous stem cell transplant (ASCT) in the treatment of multiple myeloma...

OBJECTIVES: To characterize the effect of three humanized IgG κ monoclonal antibodies (daratumumab, isatuximab, and elotuzumab) on the interpretation of results generated by protein electrophoresis, immunofixation, free light chain, and heavy/light chain assays performed on human serum. METHODS: Healthy volunteer serum and serum from multiple myeloma patients were supplemented with clinically relevant concentrations of each of the three monoclonal antibodies. These specimens then underwent analysis via serum protein electrophoresis, immunofixation, serum free light chain quantification, heavy/light chain quantification, total IgG, and total protein...

Major improvements have been made in the treatment of myeloma. However, all patients, perhaps with some exceptions, eventually relapse, even after autologous stem cell transplantation (ASCT). In that setting, the combinations of new drugs, namely the IMiDs and the proteasome inhibitors along with steroids, give encouraging results in relapsed patients. The median progression-free survival (PFS) is 20 months with lenalidomide plus dexamethasone plus ixazomib and 26 months with lenalidomide plus dexamethasone plus carfilzomib...

PURPOSE: To establish a proof-of-concept for the efficacy of the anti-CD38 antibody daratumumab in the poor prognosis CD38+ CLL subtype. EXPERIMENTAL DESIGN: The mechanism of action of daratumumab was assessed in CLL primary cells and cell lines using peripheral blood mononuclear cells to analyze antibody-dependent cell cytotoxicity (ADCC), murine and human macrophages to study antibody-dependent cell phagocytosis (ADCP) or human serum to analyze complement-dependent cytotoxicity (CDC)...

A phase III trial suggests that the combination of daratumumab, bortezomib, and dexamethasone is more powerful in patients with relapsed or relapsed and refractory melanoma than bortezomib plus dexamethasone. Patients who received all three drugs had a higher overall response rate and improved 12-month progression-free survival.

Epidemiologically, multiple myeloma (MM) is a malignant disorder of plasma cells with a higher incidence among Western populations than among Asians. However, there is growing evidence of a recent increase in the age-standardized incidence rate (ASR) of MM in Asian countries, particularly Korea. Application of novel agents has resulted in significant improvement of treatment outcomes, and the advances are ongoing with the recent introduction and U.S. Food and Drug Administration's approval of newer agents, including carfilzomib, ixazomib, elotuzumab, and daratumumab...

BACKGROUND: Daratumumab (DARA) consistently interferes with routine blood bank serologic testing by directly binding to CD38 expressed on reagent red blood cells (RBCs). Treating RBCs with dithiothreitol (DTT) eliminates the DARA interference. We conducted an international, multicenter, blinded study aimed at validating the DTT method for use by blood bank laboratories worldwide. STUDY DESIGN AND METHODS: Paired plasma sample unknowns were sent to 25 participating blood bank laboratories...

BACKGROUND: Daratumumab, a human IgGκ monoclonal antibody that targets CD38, induces direct and indirect antimyeloma activity and has shown substantial efficacy as monotherapy in heavily pretreated patients with multiple myeloma, as well as in combination with bortezomib in patients with newly diagnosed multiple myeloma. METHODS: In this phase 3 trial, we randomly assigned 498 patients with relapsed or relapsed and refractory multiple myeloma to receive bortezomib (1...

Daratumumab, a human CD38 IgG1κ monoclonal antibody, has activity as monotherapy in multiple myeloma (MM). This phase 1/2 study investigated daratumumab plus lenalidomide/dexamethasone in refractory and relapsed/refractory MM. Part 1 (dose-escalation) evaluated 4 daratumumab doses plus lenalidomide (25 mg/day p.o. on Days 1 21 of each cycle) and dexamethasone (40 mg/week). Part 2 (dose-expansion) evaluated daratumumab at the recommended phase 2 dose (RP2D) plus lenalidomide/dexamethasone. Safety, efficacy, pharmacokinetics, immunogenicity and accelerated daratumumab infusions were studied...

OBJECTIVES: Recently monoclonal antibody therapy has been introduced in the treatment of multiple Myeloma (MM). One such efficacious therapy is the anti-CD38 monoclonal antibody, daratumumab (Dara). Since it is an Ig-G-kappa it can interfere with both the serum protein electrophoresis and immunofixation electrophoresis (IFE). The free light chain (FLC) assay is also useful in the diagnosis and therapeutic monitoring of MM. Hence we tested the effect of Dara on the FLC assay. METHODS: 30 serum samples from patients with known IgG-kappa (n=20) and non-IgG-kappa M -proteins (n=10) were spiked with Dara at a final concentration of 1...
