Filter by:The study of splenomegaly, and the follow-up of splenectomized patients, is one of the causes of referral of these patients to pediatric gastroenterology and oncohematology clinics, and adult internal medicine and hematology. The study and management of splenomegaly is well described among the different medical specialties to which these patients arrive. After the application of the different algorithms and the different studies that are carried out, these splenomegaly are identified as being of hepatic, infectious, inflammatory, congestive, hematological origin and primary causes. Despite these studies of splenomegaly, approximately 10-15% of these patients still remain undiagnosed. Several studies have suggested that there is an increased frequency of MGUS (monoclonal gammopathy of undetermined significance) and/or multiple myeloma (MM) among Gaucher patients. Regarding ASMD (Acid Sphingomyelinase Deficiency), few studies have been published but it seems the 21% of patient with ASMD has MGUS and 15% ASMD patients have MGUS. Moreover, patients with MGUS and Gaucher disease (GD) are at increased risk of developing MM. The objective of the present study is to increase the diagnostic sensitivity of these unknown splenomegalys, or unknown splenomegaly patients with MGUS or multiple myeoloma who remain in consultations, using the usual diagnostic clinical procedures of unknown splenomegaly and unknown splenectomy patients, where we include the extraction of a blood sample for dry drop test (DBS), where the determination of the enzymatic/genetic activity will be carried out for Gaucher disease (GD) and acid sphingomyelinase deficiency (ASMD) , analysis of LisoGl1 and LisoSM.
Ambispective, national, multicenter observational cohort study aimed at characterizing the satellite dysimmune manifestations of clonal hematopoiesis, including Vexas (Vacuoles, E1 enzyme, X-linked, Autoinflammatory and Somatic) syndrome.
The goal of the China Monoclonal Gammopathy Screening Project in First-degree Relatives of Patients With Multiple Myeloma (CHAPERONE) study is to assess the clinical significance of screening for monoclonal gammopathy (M-protein) in first-degree relatives of patients with multiple myeloma in China population, and establish a prospective cohort of individuals with monoclonal gammopathy of undetermined significance (MGUS), a precursor conditions to multiple myeloma. We will study these patients as a means to identify risk factors for progression to symptomatic multiple myeloma.
The objective of this investigator-initiated phase II single-arm open-label clinical trial is to investigate neurological response rate, safety and tolerability of Zanubrutinib 320 mg daily in combination with Rituximab 375 mg/m2 (standard therapy) for the treatment of immunoglobulin M monoclonal gammopathy of unknown significance (IgM MGUS) related polyneuropathy with Myelin Associated Glycoprotein antibodies (anti-MAG). 42 adult patients will be included in two Dutch hospitals (University Medical Center Utrecht and Amsterdam University Medical Center). This trial consists of a 6-month treatment period, after which the hematological response will be evaluated. Adequately responding participants (at least partial response) will be treated for an additional 6 months, after which hematological response will be re-evaluated. Participants with at least a very good partial response will remain on treatment. Non-responding participants will be followed for clinical outcomes only. The total study period per participant will be 36 months.
This project will pilot the expansion of the existing Taussig Outreach Program's community outreach and patient navigation model to study the multiple myeloma (MM) screening program. This involves analyzing community reception, screening program methods, reasons patients decided to participate, reasons patients declined participation, and participant views and attitudes. This study also aims to gauge the current and general understanding of MM. This study seeks to recruit participants in the pilot screening program to promote early detection. Participants who have abnormal results will receive patient navigation for further diagnostics and testing.
To provide a comprehensive MALDI-TOF mass spectrometry method for detecting, characterizing, and quantifying M-protein, and to track M-protein in a very sensitive and specific manner during patient treatment, providing a more precise test for diagnosing disease and monitoring patient response to treatment.
The researchers are doing this study to look at how butyrate levels change in participants' stool after they are on a- plant-based diet for at least 12 weeks. All participants will have monoclonal gammopathy of undetermined significance (MGUS) or smoldering multiple myeloma (SMM). We will compare how the plant-based diet, omega-3 fatty acid and curcumin supplements, and placebo (an inactive substance that looks like the study supplements) affect butyrate levels in participants' stool.
This is a phase 1/2, open label, single-center study designed to assess the safety and preliminary clinical activity of different belantamab mafodotin doses in combination with daratumumab, pomalidomide, and dexamethasone (DPd) in patients with Relapsed/ Refractory Multiple Myeloma (RRMM) previously treated with one line of therapy who are lenalidomide refractory. This will be a 2-Part study. Part 1 will evaluate the safety of belantamab mafodotin in combination with DPd in 2 cohorts and determine the Recommended Phase 2 Dose (RP2D). In the dose expansion phase (Part 2) an expansion cohort will be treated with the RP2D. The expansion cohort will randomize participants (1:1) in two groups to evaluate two alternate dose modification guidelines for corneal AEs. Part 2 will further evaluate the safety and assess the preliminary clinical activity of the belantamab mafodotin RP2D in combination with DPd. Overall, approximately 48 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is randomized. The estimated accrual period will be 12 months corresponding to an approximate total study duration of 4 years.
This is a phase 1/2, open-label study designed to assess the safety and clinical activity of different belantamab mafodotin doses in combination with lenalidomide, dexamethasone and nirogacestat in patients with transplant ineligible newly diagnosed multiple myeloma. This will be a 2-part study. In part 1 participants will be enrolled in one cohort to receive belantamab mafodotin in combination with lenalidomide, dexamethasone and nirogacestat and will determine the recommended phase 2 dose (RP2D) to be further evaluated for safety and clinical activity in the dose expansion cohort. The RP2D dose will be used in future studies in the transplant-ineligible newly diagnosed multiple myeloma (NDMM) setting. In the dose expansion phase (Part 2) an expansion cohort will be treated with the RP2D. The expansion cohort will randomize participants (1:1) in two groups to evaluate two alternate dose modification guidelines for corneal AEs. Part 2 of the study will also evaluate an alternative dose modification guideline for corneal adverse events (AEs). Overall, approximately 36 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is enrolled (follow-up period range: 3-4 years). The estimated accrual period will be 12 months, corresponding to an approximate total study duration of 4 years.
Multiple Myeloma (MM) is a rare blood cancer affecting over 5000 people a year in the UK. All cases of myeloma start with a condition called monoclonal gammopathy of undetermined significance (MGUS). MGUS occurs in approximately 3.2% of people aged 50 and over. Only a small proportion of these people - around 1% each year - will develop myeloma. Most people with MGUS have no symptoms, but a small number of people will suffer complications. This group are referred to as having monoclonal gammopathy of clinical significance (MGCS). People with myeloma frequently experience long delays in diagnosis; the delays are longer than for any other cancer. Although we know that MGUS leads to myeloma, most cases of MGUS are only found 'incidentally' when the person is having blood tests for something else. And the people who have MGUS do not have consistent testing or follow up. This situation means that 80 - 90% of people who are diagnosed with myeloma did not have an earlier MGUS diagnosis. Earlier diagnosis of myeloma might be possible with better understanding MGUS and how it should be monitored. The SECURE study will help with this. It will help confirm the rate at which people with MGUS progress to a diagnosis of myeloma. It will further understanding of screening, diagnosis, and monitoring patterns of people with MGUS and MGCS in the UK. The study aims to find out more about the role of family history and demographic factors in the development of MGUS. It will also find out more about the psychological impact of an MGUS diagnosis and individual quality of life. Patients with MGUS will be identified by their clinical care team and invited to participate in the SECURE study. Participants will be required to answer surveys and questionnaires annually for a period of 5 years or until their disease changes. The study will recruit participants from 20 NHS sites in the UK. Some will be asked to provide blood samples. SECURE is funded by Cancer Research UK (CRUK) and the National Institute for Health Research (NIHR).
