Treatment and outcome patterns in European patients with Waldenström's macroglobulinaemia: a large, observational, retrospective chart review.

Background: Treatment options for Waldenström's macroglobulinaemia are heterogeneous, and no well established treatment standards exist. Although guidelines from the Eighth International Workshop on Waldenstrom's Macroglobulinemia were published in 2016, inconsistent awareness and budget constraints have prevented their widespread implementation, and real-life treatment patterns might differ across health-care systems. We aimed to generate information about treatment and outcome patterns for patients with Waldenström's macroglobulinaemia outside of clinical trials.

Phase 1 trial of ibrutinib and carfilzomib combination therapy for relapsed or relapsed and refractory multiple myeloma.

This phase 1, dose-finding study investigated ibrutinib and carfilzomib ± dexamethasone in patients with relapsed or relapsed/refractory multiple myeloma (≥2 lines of therapy including bortezomib and an immunomodulatory agent). Of 43 patients enrolled, 74% were refractory to bortezomib and 23% had high-risk cytogenetics. No dose-limiting toxicities were observed.

Ibrutinib alone or with dexamethasone for relapsed or relapsed and refractory multiple myeloma: phase 2 trial results.

Novel therapies with unique new targets are needed for patients who are relapsed/refractory to current treatments for multiple myeloma. Ibrutinib is a first-in-class, once-daily, oral covalent inhibitor of Bruton tyrosine kinase, which is overexpressed in the myeloma stem cell population. This study examined various doses of ibrutinib ± low-dose dexamethasone in patients who received ≥2 prior lines of therapy, including an immunomodulatory agent.

Extended Treatment with Single-Agent Ibrutinib at the 420 mg Dose Leads to Durable Responses in Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma.

Ibrutinib, a first-in-class, once-daily, oral inhibitor of Bruton tyrosine kinase, promotes apoptosis, and inhibits B-cell proliferation, adhesion, and migration. Ibrutinib has demonstrated single-agent efficacy and acceptable tolerability at doses of 420 and 840 mg in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) who were treatment-naïve (TN) or had relapsed/refractory (R/R) CLL after ≥1 prior therapy in a phase Ib/II study (PCYC-1102). Subsequently, the ibrutinib 420 mg dose was approved in CLL.

Ibrutinib for patients with rituximab-refractory Waldenström's macroglobulinaemia (iNNOVATE): an open-label substudy of an international, multicentre, phase 3 trial.

Background: In the era of widespread rituximab use for Waldenström's macroglobulinaemia, new treatment options for patients with rituximab-refractory disease are an important clinical need. Ibrutinib has induced durable responses in previously treated patients with Waldenström's macroglobulinaemia. We assessed the efficacy and safety of ibrutinib in a population with rituximab-refractory disease.

A phase IIb trial of vorinostat in combination with lenalidomide and dexamethasone in patients with multiple myeloma refractory to previous lenalidomide-containing regimens.

Clinical trials of vorinostat, a Class I/II histone deacetylase inhibitor, in combination with proteasome inhibitors and immunomodulatory agents have shown activity in relapsed/refractory multiple myeloma. This phase IIb, open-label, single-institution study evaluated the efficacy of vorinostat in combination with lenalidomide and dexamethasone in lenalidomide-refractory patients. Patients were considered lenalidomide-refractory if they had no clinical response ( View Article and Find Full Text PDF

Vorinostat in Combination With Lenalidomide and Dexamethasone in Lenalidomide-Refractory Multiple Myeloma.

Background: This is a retrospective chart review to evaluate the efficacy of the addition of vorinostat to lenalidomide and dexamethasone in patients with multiple myeloma relapsed/refractory to lenalidomide and dexamethasone.

Methods: Charts from 26 consecutive patients able to obtain commercial vorinostat were analyzed for response and safety data.

Results: The overall response rate was 31%, and the clinical beneficial rate was 50%.

Phase I study of carfilzomib, lenalidomide, vorinostat, and dexamethasone in patients with relapsed and/or refractory multiple myeloma.

Research has shown that proteasome inhibitors (e.g., carfilzomib), immunomodulatory agents (e.

Three-year follow-up of treatment-naïve and previously treated patients with CLL and SLL receiving single-agent ibrutinib.

Ibrutinib is an orally administered inhibitor of Bruton tyrosine kinase that antagonizes B-cell receptor, chemokine, and integrin-mediated signaling. In early-phase studies, ibrutinib demonstrated high response rates and prolonged progression-free survival (PFS) in chronic lymphocytic leukemia (CLL). The durable responses observed with ibrutinib relate in part to a modest toxicity profile that allows the majority of patients to receive continuous therapy for an extended period.

Novel agents for the treatment of multiple myeloma: proteasome inhibitors and immunomodulatory agents.

The integration of novel agents into the treatment of multiple myeloma (MM) has shifted the focus from an incurable disease to one that is chronic, with a realistic hope of someday achieving a cure. Proteasome inhibitors and immunomodulatory agents are the backbone of novel therapies for MM. These agents are particularly important for patients with relapsed or refractory disease, a fate faced by the majority of myeloma patients over the course of their disease.

Carfilzomib: a next-generation proteasome inhibitor for multiple myeloma treatment.

Although the incidence of multiple myeloma (MM) is increasing, the median overall survival and the number of agents in the pipeline for treating MM also are increasing. Response rates higher than 80% are not uncommon in the frontline setting when the novel agents thalidomide, lenalidomide, and bortezomib are used in combination. Response rates and survival also have improved in disease that has relapsed after treatment with conventional therapies.

Phase 1 study of pomalidomide MTD, safety, and efficacy in patients with refractory multiple myeloma who have received lenalidomide and bortezomib.

This phase 1 dose-escalation study determined the maximum tolerated dose (MTD) of oral pomalidomide (4 dose levels) administered on days 1 to 21 of each 28-day cycle in patients with relapsed and refractory multiple myeloma (RRMM). After four cycles, patients who progressed or had not achieved minimal response (serum and urine M-protein reduction of ≥ 25% and ≥ 50%) could receive dexamethasone 40 mg per week. Safety and efficacy were evaluated.

Phase II trial of syncopated thalidomide, lenalidomide, and weekly dexamethasone in patients with newly diagnosed multiple myeloma.

Unlabelled: Thalidomide and lenalidomide, in combination with dexamethasone, provide response rates ranging from 63%-79% after 4 cycles of therapy. Because of toxicities such as neuropathy and myelosuppression for thalidomide and lenalidomide, respectively, dose escalation has not been pursued. We evaluated a syncopated regimen of alternating weeks of thalidomide and lenalidomide to determine if a modified schedule allows for fewer dose reductions and, subsequently, superior efficacy.

The anion gap and routine serum protein measurements in monoclonal gammopathies.

Background And Objectives: An abnormal anion gap and an increased total protein and globulin are clues to the diagnosis of monoclonal gammopathy. We explored the utility of these markers in IgG, IgA, IgM, and free light chain monoclonal gammopathies.

Design, Setting, Participants, & Measurements: The anion gap, Na(+) - (Cl(-) + HCO(3)(-)), corrected for hypoalbuminemia, was calculated in patients with monoclonal gammopathies.

Routine health maintenance in patients living with multiple myeloma: survivorship care plan of the International Myeloma Foundation Nurse Leadership Board.

Patients diagnosed with multiple myeloma are living longer because of new therapeutic options. Helping patients with multiple myeloma maintain a good state of health from the time of diagnosis and throughout their therapy leads to better quality of life. However, patients with multiple myeloma are at risk for illnesses experienced by the general population and at additional risk for illnesses related to multiple myeloma and its treatment.

Survivorship care guidelines for patients living with multiple myeloma: consensus statements of the International Myeloma Foundation Nurse Leadership Board.

Novel therapies approved over the past decade for the management of multiple myeloma have contributed to improved overall survival in patients with newly diagnosed and relapsed disease. Nurses play a key role in educating, advocating for, and supporting patients throughout the continuum of care. Identifying potential and actual comorbid conditions associated directly with multiple myeloma and its treatment is important, as is confirming those that are patient specific so that prompt intervention can take place; therefore, the International Myeloma Foundation Nurse Leadership Board identified the most significant needs of patients diagnosed with multiple myeloma as bone health, health maintenance, mobility and safety, sexual dysfunction, and renal health.

Steroid-associated side effects in patients with multiple myeloma: consensus statement of the IMF Nurse Leadership Board.

Steroids have been the foundation of multiple myeloma therapy for more than 30 years and continue to be prescribed as single agents and in combination with other antimyeloma drugs, including novel therapies. Steroids cause a wide range of side effects that affect almost every system of the body. Identification and prompt management of the toxicities contribute to the success of steroid-containing antimyeloma regimens.

Management of side effects of novel therapies for multiple myeloma: consensus statements developed by the International Myeloma Foundation's Nurse Leadership Board.

Nurses play an essential role in managing the care of patients with multiple myeloma, who require education and support to receive and adhere to optimal therapy. The International Myeloma Foundation created a Nurse Leadership Board comprised of oncology nurses from leading cancer centers and community practices. An assessment survey identified the need for specific recommendations for managing key side effects of novel antimyeloma agents.
