Sustained benefit of zanubrutinib vs ibrutinib in patients with R/R CLL/SLL: final comparative analysis of ALPINE.

The ALPINE trial established the superiority of zanubrutinib over ibrutinib in patients with relapsed/refractory chronic lymphocytic leukemia and small lymphocytic lymphoma; here, we present data from the final comparative analysis with extended follow-up. Overall, 652 patients received zanubrutinib (n = 327) or ibrutinib (n = 325). At an overall median follow-up of 42.

Belantamab Mafodotin, Bortezomib, and Dexamethasone for Multiple Myeloma.

Background: Belantamab mafodotin had single-agent activity in patients with relapsed or refractory multiple myeloma, a finding that supports further evaluation of the agent in combination with standard-care therapies.

Methods: In this phase 3, open-label, randomized trial, we evaluated belantamab mafodotin, bortezomib, and dexamethasone (BVd), as compared with daratumumab, bortezomib, and dexamethasone (DVd), in patients who had progression of multiple myeloma after at least one line of therapy. The primary end point was progression-free survival.

ROSEWOOD: A Phase II Randomized Study of Zanubrutinib Plus Obinutuzumab Versus Obinutuzumab Monotherapy in Patients With Relapsed or Refractory Follicular Lymphoma.

Purpose: The combination of zanubrutinib plus obinutuzumab (ZO) was found to be well tolerated with an early signal of efficacy in a phase Ib study. ROSEWOOD is a phase II, randomized study that assessed the efficacy and safety of ZO versus obinutuzumab in patients with relapsed/refractory (R/R) follicular lymphoma (FL).

Methods: Patients with R/R FL who had received ≥2 lines of therapy, including an anti-CD20 antibody and an alkylating agent, were randomly assigned 2:1 to receive ZO or obinutuzumab (O).

Zanubrutinib or Ibrutinib in Relapsed or Refractory Chronic Lymphocytic Leukemia.

Background: In a multinational, phase 3, head-to-head trial, ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, was compared with zanubrutinib, a BTK inhibitor with greater specificity, as treatment for relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). In prespecified interim analyses, zanubrutinib was superior to ibrutinib with respect to overall response (the primary end point). Data from the final analysis of progression-free survival are now available.

Zanubrutinib Versus Ibrutinib in Relapsed/Refractory Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma: Interim Analysis of a Randomized Phase III Trial.

Purpose: Zanubrutinib is a potent, irreversible next-generation Bruton tyrosine kinase (BTK) inhibitor designed to maximize BTK occupancy and minimize off-target kinase inhibition. We hypothesized that complete/sustained BTK occupancy may improve efficacy outcomes and increased BTK specificity may minimize off-target inhibition-related toxicities.

Patients And Methods: ALPINE (ClinicalTrials.

Final Overall Survival Analysis of the TOURMALINE-MM1 Phase III Trial of Ixazomib, Lenalidomide, and Dexamethasone in Patients With Relapsed or Refractory Multiple Myeloma.

Purpose: The double-blind, placebo-controlled, phase III TOURMALINE-MM1 study demonstrated a statistically significant improvement in progression-free survival with ixazomib-lenalidomide-dexamethasone (ixazomib-Rd) versus placebo-Rd in patients with relapsed or refractory multiple myeloma. We report the final analyses for overall survival (OS).

Patients And Methods: Patients were randomly assigned to ixazomib-Rd (n = 360) or placebo-Rd (n = 362), stratified by number of prior therapies (1 2 or 3), previous proteasome inhibitor (PI) exposure (yes no), and International Staging System disease stage (I or II III).

Zanubrutinib monotherapy for patients with treatment naïve chronic lymphocytic leukemia and 17p deletion.

Patients with chronic lymphocytic leukemia or small lymphocytic lymphoma whose tumors carry deletion of chromosome 17p13.1 [del(17p)] have an unfavorable prognosis and respond poorly to standard chemoimmunotherapy. Zanubrutinib is a selective next-generation Bruton tyrosine kinase inhibitor.

c-MYC expression and maturity phenotypes are associated with outcome benefit from addition of ixazomib to lenalidomide-dexamethasone in myeloma.

Objectives: In the TOURMALINE-MM1 phase 3 trial in relapsed/refractory multiple myeloma, ixazomib-lenalidomide-dexamethasone (IRd) showed different magnitudes of progression-free survival (PFS) benefit vs placebo-Rd according to number and type of prior therapies, with greater benefit seen in patients with >1 prior line of therapy or 1 prior line of therapy without stem cell transplantation (SCT).

Methods: RNA sequencing data were used to investigate the basis of these differences.

Results: The PFS benefit of IRd vs placebo-Rd was greater in patients with tumors expressing high c-MYC levels (median not reached vs 11.

Impact of increased access to novel agents on the survival of multiple myeloma patients treated at a single New Zealand centre.

Background: The impact of changes in novel agent (NA) usage on the survival of multiple myeloma (MM) patients in real-world hospital settings is unclear. In New Zealand (NZ) in 2011, frontline bortezomib became available and thalidomide availability was expanded.

Aim: This retrospective study analyses the impact these change had on the survival of MM patients treated at a NZ hospital.

Outcomes of patients with myelofibrosis treated with compassionate use pacritinib: a sponsor-independent international study.

Myelofibrosis (MF) is a chronic yet progressive myeloid neoplasm in which only a minority of patients undergo curative therapy, hematopoietic stem cell transplantation. Ruxolitinib, a JAK1/2 inhibitor, is the lone therapy approved for MF, offering a clear symptom and spleen benefit at the expense of treatment-related cytopenias. Pacritinib (PAC), a multi-kinase inhibitor with specificity for JAK2, FLT3, and IRAK1 but sparing JAK1, has demonstrated clinical activity in MF with minimal myelosuppression.

Ixazomib significantly prolongs progression-free survival in high-risk relapsed/refractory myeloma patients.

Certain cytogenetic abnormalities are known to adversely impact outcomes in patients with multiple myeloma (MM). The phase 3 TOURMALINE-MM1 study demonstrated a significant improvement in progression-free survival (PFS) with ixazomib-lenalidomide-dexamethasone (IRd) compared with placebo-lenalidomide-dexamethasone (placebo-Rd). This preplanned analysis assessed the efficacy and safety of IRd vs placebo-Rd according to cytogenetic risk, as assessed using fluorescence in situ hybridization.

An individualised risk-adapted protocol of pre- and post transplant zoledronic acid reduces bone loss after allogeneic stem cell transplantation: results of a phase II prospective trial.

Bone loss occurs frequently following allogeneic haematopoietic stem cell transplantation (alloSCT). The Australasian Leukaemia and Lymphoma Group conducted a prospective phase II study of pretransplant zoledronic acid (ZA) and individualised post-transplant ZA to prevent bone loss in alloSCT recipients. Patients received ZA 4 mg before conditioning.

Pacritinib versus best available therapy for the treatment of myelofibrosis irrespective of baseline cytopenias (PERSIST-1): an international, randomised, phase 3 trial.

Background: Available therapies for myelofibrosis can exacerbate cytopenias and are not indicated for patients with severe thrombocytopenia. Pacritinib, which inhibits both JAK2 and FLT3, induced spleen responses with limited myelosuppression in phase 1/2 trials. We aimed to assess the efficacy and safety of pacritinib versus best available therapy in patients with myelofibrosis irrespective of baseline cytopenias.

Precision oncology for acute myeloid leukemia using a knowledge bank approach.

Underpinning the vision of precision medicine is the concept that causative mutations in a patient's cancer drive its biology and, by extension, its clinical features and treatment response. However, considerable between-patient heterogeneity in driver mutations complicates evidence-based personalization of cancer care. Here, by reanalyzing data from 1,540 patients with acute myeloid leukemia (AML), we explore how large knowledge banks of matched genomic-clinical data can support clinical decision-making.

A DNA target-enrichment approach to detect mutations, copy number changes and immunoglobulin translocations in multiple myeloma.

Genomic lesions are not investigated during routine diagnostic workup for multiple myeloma (MM). Cytogenetic studies are performed to assess prognosis but with limited impact on therapeutic decisions. Recently, several recurrently mutated genes have been described, but their clinical value remains to be defined.

Genomic Classification and Prognosis in Acute Myeloid Leukemia.

Background: Recent studies have provided a detailed census of genes that are mutated in acute myeloid leukemia (AML). Our next challenge is to understand how this genetic diversity defines the pathophysiology of AML and informs clinical practice.

Methods: We enrolled a total of 1540 patients in three prospective trials of intensive therapy.

Oral Ixazomib, Lenalidomide, and Dexamethasone for Multiple Myeloma.

Background: Ixazomib is an oral proteasome inhibitor that is currently being studied for the treatment of multiple myeloma.

Methods: In this double-blind, placebo-controlled, phase 3 trial, we randomly assigned 722 patients who had relapsed, refractory, or relapsed and refractory multiple myeloma to receive ixazomib plus lenalidomide-dexamethasone (ixazomib group) or placebo plus lenalidomide-dexamethasone (placebo group). The primary end point was progression-free survival.

Outcomes of allogeneic haemopoietic stem cell transplants at a small New Zealand centre: does size matter?

Background: Reduced intensity conditioning (RIC) protocols for allogeneic haemopoietic cell transplants (HCT) have become commonplace treatments for patients with haematological disease, extending allogeneic HCT to older and less fit patients. There is a perception that centres treating larger numbers of patients have improved outcomes.

Aims: We wanted to examine whether outcomes for adult allogeneic HCT patients from our smaller centre were equivalent to those expected at larger centres internationally.

Survival of myeloma patients following the introduction of thalidomide as a second-line therapy: a retrospective study at a single New Zealand centre.

Aim: This retrospective study compares the overall survival (OS) of multiple myeloma (MM) patients following treatment at a New Zealand hospital over a period in which novel therapies were available but restricted, almost exclusively, to thalidomide as a second-line therapy.

Methods: Clinical, laboratory and OS data were collected on 361 MM patients who were treated at Christchurch Hospital during 2000-2010. Patients were subdivided according to the clinical criteria used to determine front-line treatment decisions.

Allogeneic hematopoietic cell transplant for multiple myeloma using reduced intensity conditioning therapy, 1998-2006: factors associated with improved survival outcome.

This study reports on the outcome of 95 allogeneic hematopoietic cell transplants (HCTs) using reduced intensity conditioning (RIC) performed for patients with multiple myeloma (MM) in Australia and New Zealand between 1998 and 2006. The median age at HCT was 52 years. Of the 32 patients for whom the allograft was performed as a first transplant, 15 (47%) had their allograft less than 1 year from diagnosis, while for the 63 patients who had an allograft following an autograft, nine (14%) were allografted within 1 year post-diagnosis (p < 0.

Chronic myeloid leukemia in the Asia-Pacific region: current practice, challenges and opportunities in the targeted therapy era.

Chronic myeloid leukemia (CML) management varies across Asia due to disparities in affluence and healthcare provision. We surveyed CML management practice at 33 hospitals in 14 countries/regions to identify treatment challenges and opportunities for harmonization. Patients were generally treated according to international guidelines; however, tyrosine kinase inhibitors (TKIs) and molecular monitoring are inaccessible to many patients not covered by national insurance or eligible for subsidized treatment.

Rituximab plus fludarabine and cyclophosphamide prolongs progression-free survival compared with fludarabine and cyclophosphamide alone in previously treated chronic lymphocytic leukemia.

Purpose: Rituximab, a monoclonal antibody that targets the CD20 cell surface antigen, has clinical activity in patients with non-Hodgkin's lymphoma and other B-lymphocyte disorders when administered alone or in combination with chemotherapy. Promising results have previously been reported in nonrandomized studies in patients with chronic lymphocytic leukemia (CLL). This trial was designed to compare chemoimmunotherapy with chemotherapy alone in patients with previously treated CLL.
