Trial Summary
What is the purpose of this trial?This is an open label, phase II study to assess the efficacy, safety, and tolerability of Reparixin in patients with DIPSS intermediate-2, or high-risk primary myelofibrosis (PMF), post essential thrombocythemia/polycythemia vera related MF (Post ET/PV MF) after prior treatment, and those who are ineligible or refuse treatment, with a Janus kinase inhibitor (JAKi). 26 patients will be enrolled. Eligible patients will receive oral reparixin three times daily on a 4-week cycle for a core study period of 6 cycles (24 weeks). After cycle 6, patients may continue receiving reparixin once daily on a 4-week cycle if at least stable disease (SD) is met by IWG-MRT criteria until loss of response, disease progression, unacceptable toxicity, patient/physician withdrawal, or termination of study by sponsor.
What safety data is available for Reparixin in treating myelofibrosis?The provided research does not contain any safety data for Reparixin in the treatment of myelofibrosis. The studies focus on the safety and side effects of ruxolitinib and other JAK inhibitors for myelofibrosis, but do not mention Reparixin.235812
Is the drug Reparixin a promising treatment for myelofibrosis?The information provided does not mention Reparixin, so we cannot determine if it is a promising treatment for myelofibrosis based on this data.1491011
Do I have to stop taking my current medications for the trial?The trial protocol does not specify if you must stop taking your current medications. However, you must stop any MF-directed drug treatments at least two weeks before enrolling, except for hydroxyurea.
What data supports the idea that Reparixin for Myelofibrosis is an effective drug?The available research does not provide any data on Reparixin being an effective treatment for Myelofibrosis. Instead, it focuses on other drugs like ruxolitinib, fedratinib, momelotinib, and pacritinib, which are used to treat Myelofibrosis. Ruxolitinib, for example, has been shown to reduce symptoms and spleen size, although some patients may not tolerate it well. Fedratinib has also been approved for use and is effective for some patients who do not respond to ruxolitinib. There is no mention of Reparixin in the context of Myelofibrosis treatment in the provided information.467810

Efficacy of ruxolitinib for myelofibrosis. [2021]The discovery of the activating JAK2 V617F mutation in patients with myelofibrosis (MF) led to the development of JAK2 inhibitors. The first such inhibitor to enter clinical trials was ruxolitinib . This review summarizes preclinical and clinical data of ruxolitinib in MF.
Pacritinib: a new agent for the management of myelofibrosis? [2021]Myelofibrosis (MF) is a clonal haematological disease associated with recurrent somatic gene mutations (JAK2V617F, MPL, CALR) and constitutive activation of the Janus kinase (JAK)/Signal Transducer and Activator of Transcription pathway. MF is often characterised by debilitating symptoms and JAK inhibitors (JAKIs) have revolutionised available therapeutic options. Ruxolitinib, a JAK1 and 2 inhibitor, is the only currently approved agent. Several other JAKIs are undergoing evaluation in the clinical trial setting and Pacritinib , a novel JAK2 and FLT3 inhibitor, is at an advanced stage of investigation with recent completion of a Phase III trial and another ongoing.
Managing side effects of JAK inhibitors for myelofibrosis in clinical practice. [2021]Myelofibrosis (MF) is characterized by bone marrow fibrosis, abnormalities in peripheral counts, extramedullary hematopoiesis, splenomegaly and an increased risk of transformation to acute myeloid leukaemia. The disease course is often heterogeneous and management can range from observation alone through to allogeneic stem cell transplantation. As of 2017, the only approved medication for MF remains the JAK Inhibitor (JAKi), ruxolitinib (Novartis Pharmaceuticals, Basel, Switzerland; Incyte, Wilmington, Detroit, USA) although several others have reached advanced stages of clinical trials. Areas covered: In this review, we focus on the management of both common and uncommon side effects arising from the use of currently approved and clinical trial JAKi. Most of the discussion concerns ruxolitinib although we also cover both pacritinib (CTI BioPharma) and momelotinib (Gilead Sciences, Foster City, California) which have been in recent large, multinational phase III trials. The various approaches to management of JAKi-related side effects are discussed - with particular emphasis to anaemia, thrombocytopaenia and infection risk. Expert commentary: JAK inhibitors are effective in many individuals with MF and have revolutionized the current treatment paradigm. The side effect profile, in the most, is predictable and manageable with high degrees of clinical surveillance and dose modifications.
Long-term survival in patients treated with ruxolitinib for myelofibrosis: COMFORT-I and -II pooled analyses. [2021]Myelofibrosis (MF) is associated with a variety of burdensome symptoms and reduced survival compared with age-/sex-matched controls. This analysis evaluated the long-term survival benefit with ruxolitinib, a Janus kinase (JAK)1/JAK2 inhibitor, in patients with intermediate-2 (int-2) or high-risk MF.
Epidemiology, outcome, and risk factors for infectious complications in myelofibrosis patients receiving ruxolitinib: A multicenter study on 446 patients. [2022]Infections represent one of the major concerns regarding the utilization of ruxolitinib (RUX) in patients with myelofibrosis. With the aim to investigate epidemiology, outcome and risk factors for infections in RUX-exposed patients, we collected clinical and laboratory data of 446 myelofibrosis patients treated with RUX between June 2011 and November 2016 in 23 European Hematology Centers. After a median RUX exposure of 23.5 months (range, 1-56), 123 patients (28%) experienced 161 infectious events (grades 3-4 32%, fatal 9%), for an incidence rate of 17 cases per 100 pts/y. The rate of infections tended to decrease over time: 14% of patients developed the first infection within 6 months, 5% between 6 and 12 months, 3.7% between 12 and 18 months, 3.4% between 18 and 24 months, and 7.9% thereafter (P
A phase 2 study of ruxolitinib in combination with azacitidine in patients with myelofibrosis. [2021]Ruxolitinib (RUX)-based combinations may provide benefit for patients with myelofibrosis (MF). In this open-label, nonrandomized, prospective phase 2 study, patients with MF initially received RUX twice per day continuously in 28-day cycles for the first 3 cycles. Azacitidine (AZA) 25 mg/m2 (days 1-5) was added starting with cycle 4 and could be subsequently increased to 75 mg/m2 (days 1-5). Forty-six patients were enrolled with a median follow-up of 28 months (range, 4-50+ months). An International Working Group for Myelofibrosis Research and Treatment (IWG-MRT) response was achieved in 33 patients (72%), with a median time to response of 1.8 months (range, 0.7-19.0 months). One-fourth (7 of 33) of the IWG-MRT responses occurred after the addition of AZA. A reduction of >50% in palpable spleen length at 24 weeks and at any time on the study was achieved in 62% and 71% of the evaluable patients, respectively. Among patients who achieved a >50% reduction in spleen length at 24 weeks, 95% had maintained it at 48 weeks. Notably, improvements in bone marrow reticulin fibrosis grade occurred in 57% of the patients at 24 months. Treatment discontinuations as a result of drug-related toxicities occurred in 4 patients (9%), all as a result of cytopenias. New onset grade 3 to 4 anemia and thrombocytopenia occurred in 35% and 26% of patients, respectively. RUX and AZA were safe, with encouraging spleen response rates and improvement in bone marrow fibrosis in patients with MF. This trial was registered at www.clinicaltrials.gov as #NCT01787487.
The role of fedratinib for the treatment of patients with primary or secondary myelofibrosis. [2021]Myelofibrosis (MF) is a chronic myeloid neoplasm characterized by either primary myelofibrosis, or secondary MF following essential thrombocythemia or polycythemia vera. Historically, therapy has been symptom directed; however, in 2011, the first janus kinase inhibitor (JAK-i) - ruxolitinib - was approved for treatment. This medication was found to be effective in reduction of symptom burden and spleen size; however, the median duration of response is about 3 years. In addition, many patients are intolerant or develop toxicities to ruxolitinib, including patients with anemia, as well as thrombocytopenia. Therefore, there is a critical need for alternate therapeutic options for patients with MF. Additional JAK-i have been developed over the last 8 years, including fedratinib, momelotinib, and pacritinib. Fedratinib recently received approval for treatment of MF both in the first-line and second-line setting. It has shown efficacy in the first-line setting, as well as in 30% of patients who are refractory/intolerant of ruxolitinib. This review covers the trials that have led to the approval of ruxolitinib as well as fedratinib, as well as reviews of two JAK inhibitors that are still under clinical investigation: momelotinib and pacritinib.
Patterns of Care for Older Patients With Myelofibrosis: A Population-based Study. [2022]Current treatments for myelofibrosis (MF) are largely palliative, with the JAK inhibitor ruxolitinib being the breakthrough approved for higher-risk patients by the United States Food and Drug Administration in November 2011. There are limited data on the "real-world" clinical experiences among patients with MF who are treated in the JAK inhibitor era.
Light and shade of ruxolitinib: positive role of early treatment with ruxolitinib and ruxolitinib withdrawal syndrome in patients with myelofibrosis. [2022]Myelofibrosis (MF) is characterized by ineffective and hepatosplenic extramedullary hematopoiesis due to fibrotic changes in the bone marrow and systemic manifestations due to aberrant cytokine release. Ruxolitinib (RUX) is the first JAK1/JAK2 inhibitor that is clinically approved to treat splenomegaly by ameliorating inflammatory cytokines and myeloproliferation in MF.
Moving beyond ruxolitinib failure in myelofibrosis: evolving strategies for second line therapy. [2023]Ruxolitinib has been the cornerstone of pharmacologic therapy for myelofibrosis for over a decade. However, the last several years have witnessed the regulatory approval of other Janus kinase (JAK) inhibitors for myelofibrosis, i.e. fedratinib, pacritinib, and US approval of momelotinib is widely anticipated in 2023.
Rapid Hepatomegaly From Ruxolitinib Discontinuation Syndrome. [2023]Ruxolitinib (RUX) is a Food and Drug Administration-approved Janus Kinase (JAK) inhibitor shown to be effective in improving hypercatabolic symptoms and splenomegaly in patients with myelofibrosis (MF). RUX therapy provides symptomatic benefits for MF patients but is often discontinued for various reasons including worsening cytopenias. Ruxolitinib Discontinuation Syndrome (RDS) involves an acute cytokine-storm rebound phenomenon that can manifest as an acute relapse of symptoms, worsening splenomegaly, respiratory distress, systemic inflammatory response syndrome, or disseminated intravascular coagulopathy.
Ten years of treatment with ruxolitinib for myelofibrosis: a review of safety. [2023]Myelofibrosis (MF) is a chronic myeloproliferative neoplasm characterized by bone marrow fibrosis, anemia, extramedullary hematopoiesis, and splenomegaly. Patients with MF are at risk for reduced survival versus the general population and often experience burdensome signs and symptoms that reduce quality of life. The oral Janus kinase (JAK) 1/JAK2 inhibitor ruxolitinib was initially approved by the US Food and Drug Administration in 2011 for the treatment of patients with intermediate or high-risk MF, including primary MF, post-polycythemia vera MF, and post-essential thrombocythemia MF, based on efficacy and safety findings from the randomized, controlled, phase 3 COMFORT trials. Over a decade later, ruxolitinib continues to be the standard of care in higher-risk MF, and dose optimization and management remain crucial for safely maximizing clinical benefits of ruxolitinib. This review summarizes the safety profile of ruxolitinib in patients with MF in the COMFORT trials leading up to approval and in the subsequent JUMP, ROBUST, EXPAND, and REALISE trials; in pooled analyses; and in postmarketing analyses in the 10 years following approval. There is a focus on the occurrence of common hematologic and nonhematologic adverse events, with guidance provided on the management of patients with anemia or thrombocytopenia, including dosing strategies based on findings from the REALISE and EXPAND trials. Finally, to ensure a greater understanding of the safety profile of ruxolitinib, practical considerations are discussed.
