A Phase 3, Randomized, Double-blind, Add-on Study Evaluating the Safety and Efficacy of Navtemadlin Plus Ruxolitinib vs Placebo Plus Ruxolitinib in JAK Inhibitor-Naïve Patients With Myelofibrosis Who Have a Suboptimal Response to Ruxolitinib

This clinical trial is evaluating whether addition of navtemadlin to ruxolitinib treatment will provide more clinical benefit than ruxolitinib alone for patients with Myelofibrosis who have a suboptimal response to ruxolitinib treatment alone.
Subjects will start by receiving ruxolitinib alone in the run-in period. Those who demostrate a suboptimal response from ruxolitinib alone will then be randomized 2:1 to receive navtemadlin or navtemadlin placebo as add-on treatment to their ongoing ruxolitinib. Randomized means that subjects will be assigned to a group by chance, like a flip of a coin. The study is blinded, meaning the subjects, doctors, central endpoint assessors and sponsor will not know which add on treatment (navtemadlin or navtemadlin placebo) the subject is receiving.

Inhibitors of murine double minute homolog 2 (MDM2) represent a promising therapeutic approach for the treatment of TP53 wild-type glioblastomas (GBMs), reactivating p53 signaling to induce cancer cell death. We conducted a surgical window-of-opportunity trial (NCT03107780) of the MDM2 inhibitor navtemadlin (KRT-232) in 21 patients with TP53 wild-type recurrent GBM to determine achievable drug concentrations within tumor tissues and biological mechanisms of response and resistance. Participants received navtemadlin at 120 mg ( n = 10) or 240 mg ( n = 11) for 2 days before surgical resection and after surgery until progression or unacceptable toxicity. Both 120 and 240 mg daily dosing achieved a pharmacodynamic impact, but median progression-free survival was 3.1 months. DNA sequencing of three recurrent tumors revealed an absence of TP53 -inactivating mutations, indicating alternative mechanisms of resistance. To understand the mechanisms of response and resistance associated with navtemadlin, we conducted functional and spatial analyses of human tissue and patient-derived GBM neurosphere models. Navtemadlin induced partial tumor cell death as monotherapy, and combination with temozolomide enhanced apoptosis in GBM neurospheres while sparing normal bone marrow cells in vitro. We also observed up-regulation of oligodendrocyte differentiation genes with navtemadlin treatment and enrichment of oligodendrocyte transcription factor 2 (OLIG2)–positive cells at relapse, suggesting an unexplored mechanism of navtemadlin tolerance in GBM. Overall, these results indicated that clinically achievable doses of navtemadlin exert pharmacodynamic effects on GBM and suggest that combined treatment with temozolomide may be a route to more durable survival benefits.

Anticancer effects and mechanisms of Pulsatilla chinensis, Bupleurum chinense and Polyporus umbellatus on human lung carcinoma and hepatoma cells

Article

Author: Liu, Hongmin ; Song, Xiya ; Zhang, Cheng ; Turkez, Hasan ; Jin, Han ; Pan, Chengxue ; Uhlen, Mathias ; Yang, Hong ; Kim, Woonghee ; Fu, Ling ; Mardinoglu, Adil ; Kong, Xiangtai ; Li, Mengzhen ; Bi, Yuefeng

Herbs are extensively utilized in Traditional Chinese Medicine (TCM) for lung and liver cancer treatment, but the mechanisms behind these herbs remain largely unknown. Here, high-throughput transcriptomic analysis technology was used to uncover molecular mechanisms of herbal treatment. Furthermore, we developed a compound recognition approach utilizing the LINCS L1000 database to identify potential treatment targets. Our results showed that among 14 herbs tested, Pulsatilla chinensis exhibited the strongest anticancer effects in A549 and Huh7 cells, followed by Bupleurum chinense, and Polyporus umbellatus. P. chinensis exerts its anticancer properties by downregulating cell cycle-related transcription factors, including E2F1 and TFDP1. Notably, the mechanisms of P. chinensis treatment differed between the two cell lines. In A549 cells, which possess wild-type p53, P. chinensis induced apoptosis through the regulation of the p53 pathway. In contrast, in Huh7 cells, which harbor mutant p53, the effect was mediated via the TNF-α/NF-κB signaling pathway. We also identified two drugs, AMG232 and Nutlin-3, that exhibited treatment effects similar to P. chinensis in A549 cells. Both drugs function as inhibitors of the MDM2-p53 interaction. Western blot analysis confirmed the alteration of the relevant proteins, aligning with our computational predictions. Furthermore, 23-hydroxybetulinic acid, a key active compound of P. chinensis, demonstrated the ability to inhibit the p53-MDM2 interaction by binding to the same pocket on the MDM2 protein.

Icariin targets p53 to protect against ceramide-induced neuronal senescence: Implication in Alzheimer's disease

Article

Author: Wu, Beibei ; Zhu, Lemei ; Peng, Weijun ; Xiao, Qiao ; Tang, Hanfen

BACKGROUND:

Alzheimer's disease (AD) is a leading cause of dementia. The aging brain is particularly vulnerable to various stressors, including increased levels of ceramide. However, the role of ceramide in neuronal cell senescence and AD progression and whether icariin, a natural flavonoid glucoside, could reverse neuronal senescence remain inadequately understood.

AIM:

In this study, we explore the role of ceramide in neuronal senescence and AD, and whether icariin can counteract these effects.

METHODS:

We pretreated HT-22 cells with icariin and then induced senescence with ceramide. Various assays were employed to assess cell senescence, such as reactive oxygen species (ROS) production, cell cycle progression, β-galactosidase staining, and expression of senescence-associated proteins. In vivo studies utilized APP/PS1 mice and C57BL/6J mice injected with ceramide to evaluate behavioral changes, histopathological alterations, and senescence-associated protein expression. Transcriptomics, molecular docking, molecular dynamics simulations, and cellular thermal shift assays were employed to verify the interaction between icariin and P53. The specificity of icariin targeting of P53 was further confirmed through rescue experiments utilizing the P53 activator Navtemadlin.

RESULTS:

Our data demonstrated that ceramide could induce neuronal senescence and AD-related pathologies, which were reversed by icariin. Moreover, molecular studies revealed that icariin directly targeted P53, and its neuroprotective effects were attenuated by P53 activation, providing evidence for the role of P53 in icariin-mediated neuroprotection.

CONCLUSION:

Icariin demonstrates a protective effect against ceramide-induced neuronal senescence by inhibiting the P53 pathway. This identifies a novel mechanism of action for icariin, offering a novel therapeutic approach for AD and other age-related neurodegenerative diseases.

Myelofibrosis Market is Going to Grow at a CAGR of 9% in the Next Ten Years (2025-2034) | DelveInsight

The launch of emerging therapies like BESREMi (PharmaEssentia and AOP Orphan Pharmaceuticals), INCB057643 (Incyte), XPOVIO (Karyopharm Therapeutics), RYTELO (Geron), REBLOZYL (Bristol Myers Squibb), Navtemadlin (Kartos Therapeutics), Pelabresib (Novartis), and others is going to shift the myelofibrosis market. LAS VEGAS, Sept. 3, 2025 /PRNewswire/ -- DelveInsight's Myelofibrosis Market Insights report includes a comprehensive understanding of current treatment practices, emerging myelofibrosis drugs, market share of individual therapies, and current and forecasted myelofibrosis market size from 2020 to 2034, segmented into leading markets (the US, EU4, UK, and Japan). Myelofibrosis Market Summary The total myelofibrosis treatment market size in the leading markets (the US, EU4, UK, and Japan) was USD 2.2 billion in 2024. The United States accounts for the largest market size of myelofibrosis, in comparison to EU4 (Germany, Italy, France, and Spain) and the UK, and Japan. Based on DelveInsight's assessment in 2024, the 7MM had approximately 56K patient pool (prevalent cases) of myelofibrosis. Key myelofibrosis companies, including PharmaEssentia, AOP Orphan Pharmaceuticals, Incyte, Karyopharm Therapeutics, Geron, Bristol Myers Squibb, Kartos Therapeutics, Novartis, Merck, Telios Pharma, Ryvu Therapeutics, Sumitomo Pharma, Syntara, Disc Medicine, Menarini Group, and others, are actively working on innovative myelofibrosis drugs. Some of the key myelofibrosis therapies in clinical trials include BESREMi (ropeginterferon alfa-2b-njft/P-1101), INCB057643, XPOVIO (NEXPOVIO/selinexor/KPT-330), RYTELO (imetelstat), REBLOZYL (luspatercept/ACE-536), Navtemadlin (KRT-232), Pelabresib (DAK539), Bomedemstat (IMG-7289/MK-3543), TL-895, RVU120 ( SEL-120), TP-3654 (nuvisertib), SNT-5505 (PXS-5505), DISC-0974, ELZONRIS (tagraxofusp/SL-401), and others. These novel myelofibrosis therapies are anticipated to enter the myelofibrosis market in the forecast period and are expected to change the market. By 2034, among all the therapies, the highest revenue is expected to be generated by OJJAARA/OMJJARA. Discover which myelofibrosis therapies are expected to grab the largest market share @ Myelofibrosis Market Report Key Factors Driving the Growth of the Myelofibrosis Market Novel Therapies Drive Myelofibrosis Treatment Advancements Currently, four JAK inhibitors have been approved by the US FDA for the treatment of myelofibrosis, including JAKAFI (ruxolitinib), INREBIC (fedratinib), VONJO (pacritinib), and OJJAARA (momelotinib). No drug therapy can cure myelofibrosis. As myelofibrosis primarily affects older adults, stem cell transplantation is not a treatment option for most myelofibrosis patients. The launch of another JAK inhibitor, BESREMi, will further change the dynamics of the myelofibrosis market. Rich clinical pipeline and emerging non-JAK approaches driving the myelofibrosis landscape Beyond JAK inhibitors, active clinical development includes BET inhibitors (Incyte's INCB057643; Novartis' Pelabresib), XPO1 inhibitor (Karyopharm Therapeutics' XPOVIO), Telomerase inhibitor (Geron's RYTELO), MDM2 protein inhibitor (Kartos Therapeutics' Navtemadlin), Tyrosine kinase inhibitors (Telios Pharma's TL-895), PIM1 kinase inhibitor (Sumitomo Pharma's TP-3654), LOX inhibitor (Syntara's SNT-5505), and others, raising market potential by promising new label expansions, second-line options, and higher-value therapies should any prove to be disease-modifying. An aging population & increasing incidence with better survival Myelofibrosis primarily affects older adults; population aging increases the absolute number of patients. As treatments improve symptoms and (in some cases) survival, prevalent patient pools grow, supporting longer-term market demand. In the US in 2024, the 70+ years of age group had the highest number of cases, accounting for approximately 60% of the total prevalent cases, while the ≤39 years of age group accounted for just ~2%. Diagnostic & genomic testing improvements are driving myelofibrosis patient pool, leading to the growth of myelofibrosis market Wider use of molecular profiling (JAK2, CALR, MPL, and others) enables earlier and more accurate MF diagnosis and better patient stratification for targeted therapies. This both expands the diagnosed population and helps match patients to appropriate, often higher-value, treatments. Myelofibrosis Market Analysis JAK inhibitors have become the cornerstone of treatment for patients with myelofibrosis, offering significant benefits such as spleen reduction, symptom relief, and improved quality of life, which can also extend survival in those with advanced disease. All approved JAK inhibitors primarily target JAK2, particularly the wild-type form, but they differ in their activity against other JAK family members. For instance, JAKAFI myelofibrosis inhibits both JAK1 and JAK2; INREBIC selectively inhibits JAK2 while sparing JAK1 and also affects FLT3 and other targets; VONJO myelofibrosis inhibits JAK2 while sparing JAK1 but additionally impacts FLT3, IRAK, and ACVR1; and OJJAARA, approved through a different pathway, targets JAK1/JAK2 and ACVR1, mainly for myelofibrosis patients with anemia. These varying mechanisms lead to distinct patient outcomes. JAKAFI myelofibrosis continues to see strong demand and is expected to grow further, maintaining its position as the standard of care in myelofibrosis. Myelofibrosis will remain the largest segment of JAKAFI's patient population until polycythemia vera cases eventually increase. However, market growth may be limited due to patent expirations of key therapies, with JAKAFI patents set to expire in 2027 for Novartis and 2028 for Incyte, presenting potential opportunities for competitors. In response, Incyte is exploring combination trials with novel drugs to extend JAKAFI's therapeutic lifespan. Learn more about the treatment options for myelofibrosis @ Myelofibrosis Therapy The myelofibrosis treatment landscape offers significant opportunities for innovation, focusing on several key areas: Treating Lower-Risk Patients: Developing safe and effective therapies for patients with lower-risk myelofibrosis, allowing for earlier and more favorable interventions. Enhancing First-Line Treatments: Improving existing first-line therapies for intermediate- to high-risk patients through novel drugs or combination strategies. Managing Cytopenia: Developing targeted therapies to address cytopenia, a significant unmet need in patient care. Myelofibrosis Competitive Landscape The myelofibrosis clinical trial pipeline includes several drugs in mid- and late-stage development that are expected to enter the market during the forecast period. The emerging landscape offers a diverse range of therapeutic alternatives for treatment, including XPOVIO (Karyopharm Therapeutics), Elitracet (Takeda/Keros Therapeutics), Navtemadlin (Kartos Therapeutics), Pelabresib (Novartis), INCB057643 (Incyte), Bomedemstat (Merck), and others, all of which are used in various lines of treatment. The expected launch of these therapies is expected to have a further positive impact on the market. INCB57643 is an orally administered small molecule. Bromodomain and extra-terminal (BET) proteins act as epigenetic readers that control the expression of key oncoproteins implicated in the development of myelofibrosis and other hematologic malignancies, including B-lymphoma-2, nuclear factor kappa, and c-Myc. In a prior Phase I/II clinical trial, the oral BET inhibitor INCB057643, tested both as a monotherapy and in combination with ruxolitinib, demonstrated favorable tolerability and promising clinical activity in patients with advanced cancers. In its Q2 2025 financial report, the company announced that the combination of INCB057643 with ruxolitinib and INCB57643 (a JAK1/JAK2 and BET inhibitor) is currently being evaluated in a Phase II trial for myelofibrosis. RYTELO (imetelstat) is an investigational telomerase inhibitor that targets telomerase, selectively eliminating malignant stem and progenitor cells in the bone marrow, which drive diseases like myelodysplastic syndromes (MDS) and myelofibrosis. By blocking the proliferation of these malignant cells, imetelstat supports the recovery of healthy bone marrow and blood cell production and has shown disease-modifying effects and clinical benefits in Phase III trials for myelofibrosis. This mechanism sets imetelstat apart from other approved or investigational therapies for these blood cancers. In January 2025, Geron reported achieving 75% enrollment in the Phase III IMpactMF trial, which is comparing imetelstat to Best Available Therapy (BAT) in intermediate-2 or high-risk myelofibrosis patients who have relapsed or are refractory to JAK inhibitor treatment. Elritercept is a late-stage investigational activin inhibitor aimed at treating anemia associated with hematologic malignancies, including MDS and myelofibrosis. It is currently undergoing Phase II evaluation in patients with myelofibrosis. In December 2024, Keros Therapeutics presented updated data from this ongoing Phase II trial at ASH 2024. Additionally, in December 2024, Takeda announced an exclusive licensing agreement with Keros to further develop, manufacture, and commercialize elritercept globally, excluding mainland China, Hong Kong, and Macau. The anticipated launch of these emerging myelofibrosis therapies are poised to transform the myelofibrosis market landscape in the coming years. As these cutting-edge myelofibrosis therapies continue to mature and gain regulatory approval, they are expected to reshape the myelofibrosis market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth. To know more about new myelofibrosis treatment, visit @ Myelofibrosis Treatment Market Recent Developments in the Myelofibrosis Market In July 2025, Incyte announced that the Phase I data in patients with myelofibrosis as monotherapy and in combination with ruxolitinib are anticipated in the second half of 2025. In June 2025, QIAGEN and Incyte announced a new global collaboration to develop a novel diagnostic panel to support Incyte's extensive portfolio of investigational therapies for patients with myeloproliferative neoplasms (MPNs), including Incyte's monoclonal antibody INCA033989. In January 2025, Karyopharm Therapeutics stated that it expects to report top-line results from the Phase III SENTRY trial in the second half of 2025, which could represent a potentially transformative opportunity to establish a new treatment paradigm in myelofibrosis. What is Myelofibrosis? Myelofibrosis is a rare blood cancer marked by the accumulation of scar tissue, or 'fibrosis', in the bone marrow. This excess scar tissue prevents the bone marrow from producing enough healthy blood cells. It belongs to a group of blood cancers called 'myeloproliferative neoplasms (MPNs)', in which the blood cells produced by the bone marrow grow and function abnormally. When myelofibrosis arises independently, without being caused by another bone marrow disorder, it is referred to as primary myelofibrosis. In other cases, it can develop from another MPN, such as polycythemia vera or essential thrombocythemia. When this occurs, it is called secondary myelofibrosis, sometimes specifically termed post-polycythemia vera myelofibrosis or post-essential thrombocythemia myelofibrosis.

Tempus Announces Companion Diagnostic Collaboration with Kartos Therapeutics

CHICAGO--(BUSINESS WIRE)-- Tempus a leader in artificial intelligence and precision medicine, today announced a new collaboration to develop a companion diagnostic (CDx) test with Kartos Therapeutics, a clinical stage biopharmaceutical company, in support of its ongoing Phase II study of navtemadlin (KRT-232). Tempus’ CDx test, which will be developed on Tempus’ xT platform, will be used to identify patients with TP53 wild-type (TP53WT) Merkel cell carcinoma (MCC) who may be eligible for treatment with navtemadlin. Navtemadlin is a potent, selective, orally available MDM2 inhibitor that overcomes MDM2 dysregulation by restoring p53 activity and inducing apoptosis of TP53WT tumor cells. Although rare, MCC is one of the most aggressive and lethal types of skin cancer, associated with a high risk of recurrence and metastasis, making it very difficult to treat. While anti-PD-1/L-1 antibodies have become standard of care for advanced or metastatic MCC, there remains an urgent need for effective therapies for patients who fail to respond, relapse or are intolerant to immunotherapy. Kartos is collaborating with Tempus to use the xT assay, a 648-gene panel, to identify patients with advanced or metastatic MCC who have retained functional (wild-type) TP53 and who have failed or are intolerant to anti-PD-1/L-1 immunotherapy. “We are pleased to be collaborating with the Tempus team to progress our goal of developing innovative therapies that meaningfully improve the lives of patients,” said Jesse McGreivy, MD, Chief Executive Officer and Chief Medical Officer at Kartos Therapeutics. “This partnership will allow us to develop a test to identify cancer patients who may benefit from treatment with navtemadlin; a therapy which offers a unique mechanism to restore the function of p53, one of the most critical tumor suppressor proteins, resulting in apoptosis of malignant cells in TP53WT MCC and other tumor types.” “Our proprietary platform provides a comprehensive suite of solutions for novel drug development programs while also giving physicians the data needed to make informed treatment decisions for their patients,” said Michael Yasiejko, Executive Vice President at Tempus. “We look forward to supporting Kartos’ diagnostic efforts in identifying cancer patients who could benefit from a more personalized approach to their treatment using a widely-available assay and clinician-friendly tools.” About Tempus Tempus is a technology company advancing precision medicine through the practical application of artificial intelligence in healthcare. With one of the world’s largest libraries of clinical and molecular data, and an operating system to make that data accessible and useful, Tempus enables physicians to make near real-time, data-driven decisions to deliver personalized patient care and in parallel facilitates discovery, development and delivery of optimal therapeutics. The goal is for each patient to benefit from the treatment of others who came before by providing physicians with tools that learn as the company gathers more data.
