Abstract

Purpose

Myeloproliferative neoplasms (MPNs) can cause a high symptom burden that negatively affects quality of life (QoL). The way patients deal with their disease and how this impacts their QoL is important to understand, yet virtually unknown. The aim of this study is to investigate whether and how psychosocial adjustment affects QoL in MPN patients.

Methods

A longitudinal study was conducted in 338 MPN patients to investigate whether and how baseline measurements of psychosocial adjustment could predict QoL outcomes six months later. Psychosocial adjustment to illness was operationalized by: coping, self-management, resilience and illness identity (II). We tested the hypotheses that high scores on respectively problem-solving coping, self-management, resilience, II-subscales acceptance and enrichment, and low scores on II-subscales rejection and engulfment are associated with high scores on QoL. We performed a multiple hierarchical regression analysis including sociodemographic and disease-related variables and baseline QoL as control variables.

Results

II-subscale engulfment had the most pronounced negative impact on QoL (β.47, p<.001). After the introduction of the control variables, the effect of engulfment remained statistically significant (β.16, p<.01). Additionally, baseline QoL (β.32, p<.001), treatment option wait-and-see (β.11, p<.05), and MPN symptom burden at T2 (β.36, p<.001) demonstrated significance. The other variables measuring psychosocial adjustment did not relate significantly to QoL.

Conclusion

The findings of this study illustrate the significant adverse effect of engulfment on patients’ QoL, underscoring the importance of providing psychosocial guidance to mitigate the patients’ feelings of being overwhelmed by the disease.

A phase 1/3 clinical trial testing the safety and efficacy of selinexor plus ruxolitinib in patients with myelofibrosis (MF) who are Janus kinase (JAK) inhibitor-naïve is now recruiting participants for its phase 3 portion.

The global, multicenter, 2-part study aims to recruit an estimated 350 participants with MF. Participants were all at least 18 years of age.

The study consists of an experimental phase 1a, experimental phase 1b, and experimental phase 3 portion.

In the experimental phase 1a portion, 1 group of patients were given 40 mg of oral selinexor once a week on days 1, 8, 15, and 22 of each 28-day cycle together with 15 or 20 mg of ruxolitinib twice a day based on their platelet count at baseline while another group was given 60 mg of oral selinexor on the same days and the same dose of ruxolitinib as the first group.

In the experimental phase 1b, patients were given either 40 or 60 mg of oral selinexor once a week on days 1, 8, 15, and 22 of each 28-day cycle and the same dose of ruxolitinib.

In the experimental phase 3 portion, patients will either be given a fixed starting dose of 60 mg of oral selinexor or a placebo once a week on days 1, 8, 15, and 22 of each 28-day cycle together with the same dose of ruxolitinib.

The primary outcome measures of the phase 1 portion of the trial was the maximum tolerated dose and recommended phase 2 dose of selinexor and the number of participants with adverse events by severity, nature, and occurrence.

Introduction

Type 2 diabetes (T2D) and obesity have been identified as independent risk factors for various cancers, including hematologic cancers.1 Glucagon-like peptide–1 receptor agonists (GLP-1RA) have emerged as an effective treatment, offering glycemic control, weight reduction,2 and immune modulation,3 and are associated with lower cancer risk, specifically solid tumors.4 However, the association of GLP-1RA with hematologic cancers remains unexplored. This study aims to compare the risks of hematologic cancers in patients with T2D treated with GLP-1RA compared with metformin and insulin.

A new position paper combining insights from a panel discussion of German experts about the diagnosis and treatment of patients with myelofibrosis (MF) was published in the scientific journal Annals of Hematology. The paper highlights the need for an interdisciplinary approach, adherence to updated World Health Organization (WHO) and the International Consensus Classification (ICC) diagnostic criteria, and personalized treatment approaches for each patient.

The team of authors led by Florian H. Heidel, MD, from the Department of Hematology, Hemostasis, Oncology and Stem Cell Transplantation at Hannover Medical School in Hannover, Germany said that by addressing diagnostic challenges and therapeutic nuances, the paper aims to improve outcomes and quality of life for patients in the prefibrotic phase of primary MF.

The panel discussions were grouped under 3 main areas which were:

  • The definition and diagnosis of prefibrotic primary MF, its clinical characteristics, and how they separate from other subentities of myeloproliferative neoplasms.
  • Whether essential thrombocythemia and prefibrotic primary MF are distinguishable entities or part of a continuous spectrum.
  • The therapeutic options and how Janus kinase (JAK)-inhibitor therapy ranks among therapies of prefibrotic primary MF.

The relevant aspects of the panel discussion for each area were then outlined in detail.

It was concluded that profibrotic primary MF has unique morphological, clinical, and molecular characteristics that distinguish it from essential thrombocythemia and overt primary MF and that the diagnostic process relies on the histological analysis of the bone marrow, the identification of genetic mutations, and the exclusion of other myeloid neoplasms.

What to Know About Myeloproliferative Disorders Clinical Trials

Posted on by

Medically reviewed by Julie Scott, DNP, ANP-BC, AOCNP — Written by Hope Gillette on March 6, 2025

Myeloproliferative disorders, now referred to as myeloproliferative neoplasms (MPNs), include a group of blood cancers that develop when bone marrow produces too many red blood cells, white blood cells, or platelets.

Some forms of MPNs, such as essential thrombocythemia (ET) respond well to current treatmentTrusted Source, but others, such as primary myelofibrosis, have fewer effective options.

Depending on the specific diagnosis you received, your healthcare team may recommend participating in an MPN clinical trial to expand your treatment possibilities.

Author(s): Maggie L. Shaw, Andrew Kuykendall, MD

Polycythemia vera is a classic myeloproliferative neoplasm and a chronic type of leukemia, which often leads to overproduction of various blood cells. Several medications are approved to treat this condition—among them ruxolitinib (Jakafi; Incyte), in December 2014,1 and ropeginterferon alfa-2b-njft (Besremi; PharmaEssentia), in November 20212—and others remain in clinical development. Rusfertide (Takeda) is currently being investigated in the phase 3 VERIFY trial (NCT05210790), with an estimate study complete date of June 2025.3 The hepcidin mimetic has already received breakthrough therapy, orphan drug, and fast track designations from the FDA.

In this interview, Andrew Kuykendall, MD, clinical researcher at Moffitt Cancer Center and a VERIFY investigator, breaks down how polycythemia vera manifests and common ways to reduce its negative impact on patient quality of life while reducing the risk of clinically worsening events.

Abstract

A lively discussion persists regarding the diagnostic criteria for essential thrombocythemia (ET), primary myelofibrosis (PMF) and polycythemia vera (PV), particularly in relation to early/pre-fibrotic myelofibrosis (pre-PMF), a disease entity initially introduced in 2001 by the 3rd edition of the World Health Organization (WHO) classification. The definition and criteria used to diagnose pre-PMF have been progressively modified over time. The most update definition of pre-PMF can be found in the International Consensus Classification (ICC) published in 2022. An updated largely similar definition is also incorporated in the recently published 5th edition of WHO classification (2024). Diagnostic criteria for ET have undergone changes up to 2016/17 for the revised 4th edition of the WHO. In particular the threshold value for platelets were lowered and the important discrimination between “true” and “false” ET (in reality pre-PMF) been widely acknowledged. To avoid misdiagnose in early phase PV, the criteria for gender-adjusted thresholds for hemoglobin/ hematocrit have been lowered and the identification of an appropriate bone marrow (BM) morphology was upgraded as a major diagnostic criterion. Given the prominent role of morphology in MPN-related diagnostic algorithms, the diagnostic adequacy of the BM biopsy (sample procurement and proper laboratory handling) as emphasized in former WHO editions and in the ICC, was not addressed by the WHO 5th. The essential role of genetic markers is recognized by both classifications. A comparison between the revised 4th edition WHO classification and the ICC versus the WHO 5th reveals no significant differences, with the exception of the occurrence of leukoerythroblastosis in pre-PMF considered by the latter as one of the minor diagnostic criteria which seems unwarranted. In contrast to the revised 4th edition, the majority of the microscopic images used for the WHO 5th due to their low magnification and poor technique, do not highlight the diagnosis differences among these entities.

Protagonist and Takeda Announce Positive Topline Results from Phase 3 VERIFY Study of Rusfertide in Patients with Polycythemia Vera

Posted on by

March 3, 2025

− Study met the primary endpoint, with a significantly higher proportion of clinical responders on rusfertide compared to placebo

− All four key secondary endpoints were met, including EU primary endpoint and patient-reported outcomes

− Rusfertide was generally well tolerated; no new safety findings were observed in the study

NEWARK, Calif. & OSAKA, Japan & CAMBRIDGE, Mass.–(BUSINESS WIRE)–Protagonist Therapeutics, Inc. (“Protagonist”) (NASDAQ:PTGX) and Takeda (TSE:4502/NYSE:TAK) today announced positive topline results for the Phase 3 VERIFY study, in which phlebotomy-dependent patients with polycythemia vera (PV) were randomized to treatment with either rusfertide or placebo, as an add-on to standard of care treatment. The study met its primary endpoint and all four key secondary endpoints. Rusfertide is a first-in-class investigational hepcidin mimetic peptide therapeutic, which has received Orphan Drug designation and Fast Track designation from the U.S. Food & Drug Administration (FDA).

Key findings from the study include:

  • The primary endpoint of the study was met, with a significantly higher proportion of clinical responders1 among rusfertide-treated patients with PV (77%) compared to those who received placebo (33%) during weeks 20-32; p<0.0001. The primary endpoint of the study was the proportion of patients achieving a response, which was defined as the absence of phlebotomy eligibility.
  • The first key secondary endpoint, which is the pre-specified primary endpoint for European Union (EU) regulators, was also met, with a mean of 0.5 phlebotomies per patient in the rusfertide arm compared to 1.8 phlebotomies per patient in the placebo arm during weeks 0-32; p<0.0001.
  • The other three pre-specified key secondary endpoints, namely hematocrit control2 and patient-reported outcomes using PROMIS Fatigue SF-8a3 and MFSAF TSS-74, were also achieved with statistical significance.
  • Rusfertide was generally well tolerated in the Phase 3 VERIFY trial, and safety was in line with previous rusfertide clinical studies. No new safety findings were observed in the study. The majority of adverse events were grade 1-2 injection site reactions and all serious adverse events reported were deemed to be not drug related. There was no evidence of an increased risk of cancer in rusfertide-treated patients compared to those on placebo.

“The positive results of the Phase 3 VERIFY study across the primary and all key secondary endpoints provide compelling evidence of the potential for rusfertide as a first-in-class erythrocytosis-specific agent to address unmet medical needs in patients with PV who are unable to achieve adequate hematocrit control despite standard of care treatments,” said Arturo Molina, M.D., M.S., Chief Medical Officer of Protagonist. “We plan to submit additional details of these promising results for presentation at upcoming medical conferences in 2025. We are immensely grateful to the patients, study staff and principal investigators who made the VERIFY study possible.”

Genetic Testing Breakthroughs in Blood and Lymph Cancers

Posted on by

February 28, 2025

Hematopoietic and lymphocytic neoplasms (HLNs) are a diverse group of malignancies affecting blood and lymphatic systems, with outcomes varying from manageable conditions to fatal diseases. Traditional classifications rely on morphology, karyotyping, and fluorescence in situ hybridization (FISH). However, recent advancements in next-generation sequencing (NGS) allow simultaneous genetic profiling of multiple genes, enhancing diagnostic precision and therapeutic strategies. This review examines key molecular applications in diagnosing and managing HLNs, addressing current challenges and proposing solutions to optimize clinical utility.

Chronic Myeloid Leukemia (CML)

CML, historically identified by leukocytosis, is characterized by the BCR::ABL1 fusion gene resulting from the Philadelphia chromosome translocation. This oncogenic fusion drives aberrant tyrosine kinase activity, promoting unchecked proliferation. The introduction of imatinib, a targeted tyrosine kinase inhibitor (TKI), revolutionized CML treatment, leading to normalized white blood cell (WBC) counts within months. However, resistance mutations necessitate molecular monitoring via quantitative PCR, FISH, and karyotyping, ensuring optimal therapeutic adjustments.

Molecular Applications in BCR::ABL1-Negative Myeloid Neoplasms

Certain myeloid neoplasms, such as chronic neutrophilic leukemia (CNL) and chronic eosinophilic leukemia (CEL), lack the BCR::ABL1 fusion gene but exhibit distinct genetic markers like CSF3R mutations in CNL. Classical myeloproliferative neoplasms (MPNs) include polycythemia vera, essential thrombocythemia, and primary myelofibrosis, driven by JAK2, MPL, or CALR mutations. The application of NGS enables comprehensive mutational profiling, aiding accurate diagnosis and prognostication.

Fedratinib treatment is effective in patients with myelofibrosis (MF) who discontinued ruxolitinib due to treatment failure, according to data from a real-world study published in the scientific journal Future Oncology.

The findings of this study offer a new option for patients with MF whose disease does not respond to ruxolitinib treatment.

To assess the real-world treatment patterns with fedratinib as well as clinical outcomes in patients with primary or secondary MF after ruxolitinib discontinuation, a team of researchers conducted a retrospective, noninterventional medical record review of 196 patients with MF in Germany, Canada, and the United Kingdom.

Data about the patients was provided by 70 physicians of whom 78.6% were primarily hematologists or oncologists.

Of these 196 patients, the majority (76.5%) had primary MF and started treatment with fedratinib at a mean age of 67.7 .

The median duration of treatment with fedratinib was 11.5  months and the median follow-up period was 13.8  months.  Almost half (49.5%) of patients started fedratinib at the dose indicated on the label, i.e. 400  mg per day.

Six months after the start of treatment with fedratinib, 77.7% of patients had symptom response and 66.8% had spleen response.
