Associations of ofatumumab exposure and treatment outcomes in patients with untreated CLL receiving chemoimmunotherapy
2016
Relationships between patient characteristics, ofatumumab pharmacokinetics, and treatment outcomes were investigated in this phase 2 trial of ofatumumab plus fludarabine and cyclophosphamide (FC) in untreated chronic lymphocytic leukemia. Patients were randomized 1:1 to receive 500 or 1000 mg ofatumumab (Cycle 1; 300 mg) plus FC every 4 weeks for six cycles. Median C(max) and C(trough) values were similar at Cycle 1 regardless of the ultimate clinical outcome. At later doses, these values were higher for patients with complete response (CR) than for other patients. Higher C(max) and C(trough) values at Cycles 3 and 6 were significantly associated with an increased likelihood of CR, whereas …
Depth of response to isatuximab, carfilzomib, lenalidomide, and dexamethasone (Isa-KRd) in front-line treatment of high-risk multiple myeloma: Interi…
2020
8508 Background: High-risk (HR) multiple myeloma (MM) still has a significant impaired prognostic outcome. Addition of CD38 monoclonal antibodies to standard-of-care regimens significantly improved response rates and depth of response in newly diagnosed (ND) and relapsed/refractory MM patients (pts). Here, we report the prespecified end of induction interim analysis (IA) of the investigator-initiated GMMG-CONCEPT trial (NCT03104842), evaluating the quadruplet regimen isatuximab plus carfilzomib, lenalidomide and dexamethasone (Isa-KRd) in HR NDMM pts. Methods: 153 pts with HR NDMM are planned to be included into the trial. HR MM is defined by the presence of del17p or t(4;14) or t(14;16) o…
Ofatumumab Combined With Fludarabine and Cyclophosphamide (O-FC) Shows High Activity in Patients With Previously Untreated Chronic Lymphocytic Leukem…
2010
Abstract 207 Introduction: Chemoimmunotherapy regimens have become the treatment standard for patients with CLL. Ofatumumab is a human monoclonal antibody that targets a unique small-loop epitope on CD20 and elicits rapid and efficient in vitro complement-dependent cytotoxicity, as well as antibody-dependent cellular cytotoxicity. Recent studies demonstrated single-agent ofatumumab activity, with high overall response rates (ORR) in patients with refractory CLL. We conducted an international, randomized, parallel group, Phase II trial with two doses of ofatumumab combined with fludarabine and cyclophosphamide (FC) in previously untreated patients with CLL to evaluate the efficacy and tolera…

Abstract Abstract 1793 Introduction: Results: Seven pts (4 male) with a medianLittle is known about the pharmacokinetics (PK) and pharmacodynamics of CD20 monoclonal antibody (mAb) with chemotherapy in patients (pts) with CLL. Ofatumumab (O) is a human mAb targeting a membrane-proximal small-loop epitope on CD20 and mediates efficient complement-dependent cytotoxicity and antibody-dependent cell-mediated cytotoxicity. Safety and efficacy of O at 2 dose levels in combination with fludarabine and cyclophosphamide (FC) were evaluated in previously untreated pts with CLL. Relationship between O PK, baseline characteristics, and clinical outcomes were studied. Pts and Methods: Pts with active CL…
Prediction of Early Death and Severe Infections during Novel Agent-Based Induction Therapy in Newly-Diagnosed Multiple Myeloma: An Intergroup Analysi…
2021
Abstract Background: During the past decade, prognostic tools and outcomes of patients with newly-diagnosed multiple myeloma (NDMM) markedly improved. Data from clinical trials evaluating early morbidity and mortality including patients with transplant-eligible NDMM treated with novel agents are scarce. Thus, we aimed to analyze early morbidity and mortality in this patient cohort, devise and validate a predictive score to identify patients at risk. Patients and methods: Between July 2005 and January 2018, 1333 patients with transplant-eligible NDMM from three subsequent phase III trials, HD4, MM5 and HD6 from the German-speaking Myeloma Multicenter Group (GMMG), received a novel agent-base…
Improved Safety with the Use of Subcutaneous Bortezomib in Combination with Panobinostat and Dexamethasone: Preliminary Data from a Panobinostat Glob…
2016
Abstract Introduction: Panobinostat (PAN) is a potent pan-deacetylase inhibitor that targets multiple myeloma (MM) cells via its epigenetic effects as well as its effect on the aggresome. In the PANORAMA 1 phase 3 trial, the combination of PAN, bortezomib (BTZ), and dexamethasone (Dex; PAN+BTZ+Dex) significantly increased progression-free survival compared with placebo plus BTZ and Dex, leading to approval in Europe of the combination for the treatment of patients with MM who have received ≥ 2 prior regimens, including BTZ and an immunomodulatory agent. The purpose of this expanded treatment protocol (ETP) is to further evaluate safety and to provide panobinostat prior to commercial availab…
Elotuzumab in Combination with Lenalidomide, Bortezomib, Dexamethasone and Autologous Transplantation for Newly-Diagnosed Multiple Myeloma: Results f…
2021
Abstract Background: Treatment regimens including a proteasome inhibitor, immunomodulating agent and a monoclonal antibody (moAb) play an emerging role in the treatment of newly-diagnosed multiple myeloma (NDMM). This multicenter phase III trial of the German-speaking Myeloma Multicenter Group (GMMG HD6) investigated the addition of the anti-SLAMF7 moAb elotuzumab to lenalidomide / bortezomib / dexamethasone (RVd) in induction and consolidation therapy as well as to lenalidomide maintenance treatment in transplant-eligible NDMM. Patients and Methods: Patients were equally randomized into four treatment arms, stratified by International Staging System (ISS). Treatment consisted of four 21-da…
The prognostic and predictive value of IKZF1 and IKZF3 expression in T-cells in patients with multiple myeloma
2018
Purpose: While recent studies described the role of IKZF1/3 proteins in multiple myeloma (MM) cells, few have highlighted the significance of IKZF1/3 expression in T-cells. In this study we examine the prognostic and predictive value of IKZF1/3 expression in T-cells in patients with MM stage III. Experimental design: We analysed the IKZF1/3 expression levels in T-cells from 45 MM stage I (MMI) and 50 newly diagnosed MM stage III (MMIII) patients, according to Durie-Salmon staging system, by flow cytometry to examine their prognostic and predictive value. We also combined in vivo observations with in vitro assays to determine the effect of IKZF1/3 expression on the T-cell immunophenotype and…
Addition of Isatuximab to Lenalidomide, Bortezomib and Dexamethasone As Induction Therapy for Newly-Diagnosed, Transplant-Eligible Multiple Myeloma P…
2021
Abstract Background: In newly-diagnosed multiple myeloma (NDMM), lenalidomide/bortezomib/dexamethasone (RVd) is one of the most widely used combination regimens. Anti-CD38 monoclonal antibodies (CD38-moAb) increase efficacy when added to standard-of-care regimens. Here we present the first primary endpoint of the randomized, open-label, multicenter, phase III GMMG-HD7 trial, comparing RVd without (arm IA) or with the CD38-moAb isatuximab (Isa, arm IB) with regard to the rate of minimal residual disease (MRD) negativity after induction therapy in patients with transplant-eligible NDMM. Patients and Methods: Patients with transplant-eligible NDMM at 67 sites in Germany were equally randomized…
Chemoimmunotherapy with O-FC in previously untreated patients with chronic lymphocytic leukemia
2011
We conducted an international phase 2 trial to evaluate 2 dose levels of ofatumumab, a human CD20 mAb, combined with fludarabine and cyclophosphamide (O-FC) as frontline therapy for chronic lymphocytic leukemia (CLL). Patients with active CLL were randomized to ofatumumab 500 mg (n = 31) or 1000 mg (n = 30) day 1, with fludarabine 25 mg/m2 and cyclophosphamide 250 mg/m2 days 2-4, course 1; days 1-3, courses 2-6; every 4 weeks for 6 courses. The first ofatumumab dose was 300 mg for both cohorts. The median age was 56 years; 13% of patients had a 17p deletion; 64% had β2-microglobulin > 3.5 mg/L. Based on the 1996 National Cancer Institute Working Group (NCI-WG) guidelines, the complete respo…
