– The Unseen Journey brings to life the often-misunderstood impact of common myeloproliferative neoplasm (MPN) symptoms through AI-generated images developed from the words and experiences of real patients

WILMINGTON, Del.–(BUSINESS WIRE)–Incyte (Nasdaq: INCY) today announced the launch of The Unseen Journey, a program that brings to life the hidden emotional and physical toll of myeloproliferative neoplasms (MPNs), a group of rare, chronic and progressive blood cancers. Through the use of generative artificial intelligence (AI), the stories and experiences of MPN patients were transformed into unique images to help them show their health care team and their loved ones the significant impact of their MPN symptoms.

The Unseen Journey highlights the stories of people living with MPNs who were asked to describe their symptoms and how they impact their lives in their own words. As each patient described their symptoms and experiences, generative AI tools transformed their words into images that visually depict the patient’s most burdensome symptoms. The resulting images provide a vivid look at the reality of living with an MPN.

“MPN symptoms can be difficult to recognize and describe and every patient’s experience is different, which can sometimes create a challenge for patients, their loved ones and their health care teams to understand the impact of the condition to daily life,” said Ann Brazeau, CEO and Founder, MPN Advocacy and Education International. “These AI-generated images paint a vivid picture of what it is like to live with an MPN, and I hope they will help create a new level of awareness and empathy for those with these conditions.”

Treatment with rusfertide led to a 60% response rate (n = 18/30) vs 17% (n = 5/29) with placebo in patients with phlebotomy-dependent polycythemia vera (P = .002), according to updated findings from part 2 of the phase 2 REVIVE trial (NCT04057040) which were published in the New England Journal of Medicine.1

The international trial was designed with 3 parts: a 28-week, open-label, dose-finding portion in which rusfertide was added to a patient’s ongoing therapy of phlebotomy alone or cytoreductive therapy with optional phlebotomy; a double-blind, randomized withdrawal portion wherein patients were randomly assigned to receive rusfertide or placebo for 12 weeks (weeks 29 to 41); and an open-label extension period following patients on rusfertide therapy for up to 3 years.

Findings from part 1 showed that the estimated mean number of annual phlebotomies was 8.7±2.9 during the 28 weeks before the first dose of rusfertide and 0.6±1.0 during part 1 (estimated difference, 8.1 phlebotomies per year). Moreover, the mean maximum hematocrit level was 44.5±2.2% during part 1 vs 50.0±5.8% during the 28 weeks before the first dose of rusfertide. Patient quality of life was also improved on rusfertide, with a lower severity of disease-related symptoms.

“Rusfertide appears to represent a significant step forward in treating [patients with] polycythemia vera through its unique approach of limiting the amount of iron available for blood cell production,” Marina Kremyanskaya, MD, PhD, an associate professor of medicine (hematology and medical oncology) at Icahn School of Medicine at Mount Sinai in New York, New York, and lead author of the study, stated in a news release.2 “Pending further clinical studies, this injectable agent could become a valuable therapeutic tool for a disease which many patients and their physicians struggle to bring under control.”

Purpose: Myeloproliferative neoplasms (MPNs) are characterized by the overproduction of differentiated myeloid cells. Mutations in JAK2, CALR and MPL are considered drivers of Bcr-Abl-ve MPNs, including essential thrombocythemia (ET), polycythemia vera (PV), prefibrotic primary myelofibrosis (prePMF) and overt myelofibrosis (MF). However, how these driver mutations lead to phenotypically distinct and/or overlapping diseases is unclear. Experimental Design: To compare the genetic landscape of MF to ET/PV/PrePMF, we sequenced 1711 genes for mutations along with whole transcriptome RNA-seq of 137 MPN patients. Results: In addition to driver mutations, 234 and 74 genes were found to be mutated in overt MF (N=106) and ET/PV/PrePMF (N=31), respectively. Overt MF had more mutations compared to ET/PV/prePMF (5 vs 4 per subject, P=0.006). Genes frequently mutated in MF included high-risk genes (ASXL1, SRSF2, EZH2, IDH1/2 and U2AF1), and Ras pathway genes. Mutations in NRAS, KRAS, SRSF2, EZH2, IDH2 and NF1, were exclusive to MF. Advancing age, higher DIPSS and poor overall survival (OS) correlated with increased variants in MF. Ras mutations were associated with higher leukocytes and platelets, and poor OS. The comparison of gene expression showed upregulation of proliferation and inflammatory pathways in MF. Notably, ADGRL4, DNASE1L3, PLEKHGB4, HSPG2, MAMDC2 and DPYSL3 were differentially expressed in hematopoietic stem and differentiated cells. Conclusions: Our results illustrate that evolution of MF from ET/PV/PrePMF likely advances with age, accumulation of mutations, and activation of proliferative pathways. The genes and pathways identified by integrated genomics approach provide insight into disease transformation and progression, and potential targets for therapeutic intervention.

The addition of parsaclisib to stable-dose ruxolitinib treatment decreased spleen volume, improved symptom scores, and yielded acceptable safety among patients with primary or secondary myelofibrosis (MF), according to findings from a phase 2 trial published in Blood Advances.

Abdulraheem Yacoub, MD, The University of Kansas Cancer Center, Kansas City, Kansas, and coauthors explained that although ruxolitinib has demonstrated beneficial results among patients with intermediate- or high-risk myelofibrosis, “suboptimal response may occur, potentially because of signaling via the phosphoinositide 3-kinase (PI3K)/protein kinase B pathway.”

In this phase 2 trial, the study authors aimed to measure the potential benefit of adding PI3Kδ inhibitor parsaclisib to ruxolitinib treatment among patients with primary or secondary myelofibrosis who did not have optimal responses to ruxolitinib alone. The primary end points were dosing, efficacy, and safety of this treatment combination.

All patients included in this study stayed on a stable dose of ruxolitinib. Among these patients, 32 were administered parsaclisib at 10 or 20 mg once daily for 8 weeks, then once weekly afterward (daily-to-weekly dosing). Additionally, 42 patients were administered parsaclisib at 5 or 20 mg once daily for 8 weeks, and then 5 mg once daily afterward (all-daily dosing).

Author: Lynda Williams

medwireNews: Tixagevimab and cilgavimab immunoprophylaxis may help protect patients with haematological malignancies from COVID-19 infection and hospitalisation, suggests a research letter published in JAMA Oncology.

The cohort study reports the outcomes of 204 patients who were eligible for immunoprophylaxis with the two fully human SARS-CoV-2-neutralising monoclonal antibodies due to an increased risk of inadequate response to COVID-19 vaccination.

The patients were enrolled between June and September 2022 and followed-up for 6 months, during which time Omicron variants were prevalent in Italy, write Marco Salvini (ASST Sette Laghi, Varese, Italy) and co-authors.

Overall, 130 patients were given a single pre-exposure prophylactic dose of tixageviamb 150 mg and cilgavimab 150 mg, while 74 patients did not receive the treatment.

The majority of patients in the treatment and control arms had lymphoproliferative disorders or multiple myeloma (77 vs 81%), followed by myeloproliferative neoplasms (19 vs 12%) and acute leukaemia (4 vs 7%). Most patients in the two groups were undergoing active treatment (95 vs 92%), with immunotherapy, targeted therapy, chemotherapy, autologous stem cell transplantation or other treatments.

A novel treatment for polycythemia vera, a potentially fatal blood cancer, demonstrated the ability to control overproduction of red blood cells, the hallmark of this malignancy and many of its debilitating symptoms in a multi-center clinical trial led by the Icahn School of Medicine at Mount Sinai.

In the phase 2 study, the drug rusfertide limited excess production of red blood cells, the main manifestation of polycythemia vera, over the 28-week course of treatment. The results suggest it could replace therapeutic phlebotomy, a common form of treatment which has proven to be a burden for many patients. The results of the study were published today (Feb. 21) in The New England Journal of Medicine.

“Rusfertide appears to represent a significant step forward in treating polycythemia vera through its unique approach of limiting the amount of iron available for blood cell production,” says Marina Kremyanskaya, MD, Ph.D., Associate Professor of Medicine (Hematology and Medical Oncology) at Icahn Mount Sinai and lead author of the study.

Abstract: Interferons are cytokines with immunomodulatory properties and disease-modifying effects that have been used to treat myeloproliferative neoplasms (MPNs) for more than 35 years. The initial use of interferons was limited due to difficulties with administration and a significant toxicity profile. Many of these shortcomings were addressed by covalently binding polyethylene glycol to the interferon structure, which increases the stability, prolongs activity, and reduces immunogenicity of the molecule. In the current therapeutic landscape, pegylated interferons are recommended for use in the treatment of polycythemia vera, essential thrombocythemia, and primary myelofibrosis. We review recent efficacy, molecular response, and safety data for the two available pegylated interferons, peginterferon alfa-2a (Pegasys) and ropeginterferon alfa-2b-njft (BESREMi). The practical management of interferonbased therapies is discussed, along with our opinions on whether to and how to switch from hydroxyurea to one of these therapies. Key topics and questions related to use of interferons, such as their safety and tolerability, the significance of variant allele frequency, advantages of early treatment, and what the future of interferon therapy may look like, will be examined. Pegylated interferons represent an important therapeutic option for patients with MPNs; however, more research is still required to further refine interferon therapy.
