Comparative effectiveness of lenalidomide/dexamethasone-based triplet regimens for treatment of relapsed and/or refractory multiple myeloma in the United States: An analysis of real-world electronic health records data.

Background: This retrospective longitudinal study compared the effectiveness of dexamethasone+lenalidomide (Rd)-based triplet regimens containing proteasome inhibitors (PIs) ixazomib (IRd), carfilzomib (KRd), and bortezomib (VRd) or monoclonal antibodies (MABs) elotuzumab (ERd) and daratumumab (DRd) in patients with relapsed/refractory multiple myeloma (RRMM)-including those with high cytogenetic risk-primarily treated at community oncology clinics in the United States.

Methods: Electronic health records of adult RRMM patients in a deidentified real-world database (01/01/2014-09/30/2020) who initiated IRd, KRd, VRd, ERd, or DRd in the second or later line of therapy (LOT) were analyzed. The index date was the date of initiation of each LOT and baseline was the 6-month pre-index period.

INSURE: a pooled analysis of ixazomib-lenalidomide-dexamethasone for relapsed/refractory myeloma in routine practice.

We pooled data from three observational studies (INSIGHT MM, UVEA-IXA and REMIX) to investigate the real-world effectiveness of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory myeloma. INSIGHT MM was a prospective study conducted in countries across Europe, Asia and North/Latin America while UVEA-IXA and REMIX were multicenter, retrospective/prospective studies conducted in Europe. Patients who had received IRd as ≥2nd line of therapy were analyzed.

Use Via Early Access to Ixazomib (UVEA-IXA) Study: Effectiveness and Safety of Ixazomib-based Therapy in Relapsed/Refractory Multiple Myeloma Outside of the Clinical Trial Setting.

Background: In multiple myeloma (MM), improving our understanding of routine clinical practice and the effectiveness of agents outside of clinical trials is important. TOURMALINE-MM1 data resulted in approval of ixazomib for MM patients who have received ≥ 1 prior therapy.

Patients And Methods: UVEA-IXA comprised a retrospective chart review in the early access program, and a prospective 1-year follow-up period.

-class transition from bortezomib-based therapy to IRd is an effective approach in newly diagnosed multiple myeloma.

To compare the effectiveness of -class transition to all-oral ixazomib-lenalidomide-dexamethasone (IRd) following parenteral bortezomib (V)-based induction versus continued V-based therapy in US oncology clinics. Non-transplant eligible patients with newly diagnosed multiple myeloma (MM) receiving transition to IRd (N = 100; US MM-6), or V-based therapy (N = 111; INSIGHT MM). Following inverse probability of treatment weighting, overall response rate was 73.

Comparison of health care costs and resource utilization for commonly used proteasome inhibitor-immunomodulatory drug-based triplet regimens for the management of patients with relapsed/refractory multiple myeloma in the United States.

Economic differences among currently available proteasome inhibitors (PI)-based lenalidomide-dexamethasone (Rd)-backbone triplet regimens-ixazomib (I), bortezomib (V), and carfilzomib (K) plus Rd-remain poorly understood. To assess health care resource utilization (HCRU) and health care costs of patients with relapsed/refractory multiple myeloma (RRMM) in the United States treated with IRd, VRd, and KRd. This retrospective longitudinal cohort study using IQVIA PharMetrics Plus adjudicated claims US data (January 1, 2015, to September 30, 2020) included adult patients with all available data who initiated IRd, VRd, or KRd in second line of therapy or later (LOT2+) on or after September 1, 2015.

Rates of Influenza and Pneumococcal Vaccination and Correlation With Survival in Multiple Myeloma Patients.

Background: Infections are a common reason for hospitalization and death in multiple myeloma (MM). Although pneumococcal vaccination (PV) and influenza vaccination (FV) are recommended for MM patients, data on vaccination status and outcomes are limited in MM.

Materials And Methods: We utilized data from the global, prospective, observational INSIGHT MM study to analyze FV and PV rates and associated outcomes of patients with MM enrolled 2016-2019.

Understanding Amyloidosis: Unraveling the Complexities and Therapeutic Approaches for Oncology Nurses.

Background:  Primary systemic light-chain (AL) amyloidosis is a rare clonal plasma cell disorder characterized by the production of abnormal immunoglobulin fragments, which form insoluble fibrils that aggregate as amyloid deposits in organs and tissues, leading to organ dysfunction and death.

Objectives:  The aim of this literature review is to increase awareness of AL amyloidosis and educate nurses on the care of this patient population.

Methods:  This overview is based on a literature search of AL amyloidosis, including its pathogenesis, prognosis, and presentation.

Real-world comparative effectiveness of triplets containing bortezomib (B), carfilzomib (C), daratumumab (D), or ixazomib (I) in relapsed/refractory multiple myeloma (RRMM) in the US.

Multiple available combinations of proteasome inhibitors, immunomodulators (IMIDs), and monoclonal antibodies are shifting the relapsed/refractory multiple myeloma (RRMM) treatment landscape. Lack of head-to-head trials of triplet regimens highlights the need for real-world (RW) evidence. We conducted an RW comparative effectiveness analysis of bortezomib (V), carfilzomib (K), ixazomib (I), and daratumumab (D) combined with either lenalidomide or pomalidomide plus dexamethasone (Rd or Pd) in RRMM.

Ixazomib-lenalidomide-dexamethasone in routine clinical practice: effectiveness in relapsed/refractory multiple myeloma.

To evaluate the effectiveness and safety of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory multiple myeloma in routine clinical practice. Patient-level data from the global, observational INSIGHT MM and the Czech Registry of Monoclonal Gammopathies were integrated and analyzed. At data cut-off, 263 patients from 13 countries were included.

INSIGHT MM: a large, global, prospective, non-interventional, real-world study of patients with multiple myeloma.

With the introduction of new drugs with different mechanisms of action, multiple myeloma (MM) patients' outcomes have improved. However, the efficacy seen in clinical trials is often not seen in real-world settings and data on the effectiveness of MM therapies are needed. INSIGHT MM is a prospective, global, non-interventional, observational study that is enrolling approximately 4200 patients with newly diagnosed or relapsed/refractory MM, making it the largest study of its kind to date.

Targeted therapies for the treatment of leukemia.

Objectives: To review novel targeted therapies for the treatment of leukemia.

Data Sources: Professional journals, books, and government publications.

Conclusion: Nonspecific cytotoxic chemotherapeutic agents provide marginal therapeutic benefit and significant toxicity when used in the treatment of leukemia.

Colony-stimulating factors: beyond the effects on hematopoiesis.

The effects of sargramostim and filgrastim on hematopoietic cells are described. Filgrastim is a lineage-specific colony-stimulating factor (CSF), mainly affecting neutrophils. In addition to enhancing neutrophil recovery, filgrastim may also enhance neutrophil functional activity.
