Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma GCB DLBCL, a fast-growing blood cancer affecting immature B-cells. The study compares two treatment combinations to see if more people respond to zilovertamab vedotin MK-2140 plus R-CHP versus polatuzumab vedotin plus R-CHP. This Phase 2 trial aims to assess the effectiveness and safety of these regimens in participants with newly diagnosed GCB DLBCL. Participants receive either zilovertamab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone R-CHP, or polatuzumab vedotin combined with R-CHP. Treatments are given by intravenous infusion on Day 1 of each 3-week cycle for up to 6 cycles, approximately 4 months, with prednisone or prednisolone taken orally for 5 days of each cycle. For participants with high-risk DLBCL, up to 2 additional cycles of rituximab or biosimilar are given. During the study, participants are monitored for response to treatment using Lugano Response Criteria, with follow-up lasting up to about 31 months for the primary outcome. Secondary outcomes include progression-free survival, overall survival, event-free survival, duration of complete response, adverse events, and quality of life assessments. Safety and health status are regularly checked through exams, lab tests, and questionnaires over several years, with total study participation extending up to 7 years.

Researchers are evaluating the safety and effectiveness of UBT251, a medicine not yet available for prescription, in adults with type 2 diabetes. This study compares UBT251 with semaglutide, an already approved treatment, and their respective placebos. The goal is to see how well different doses of UBT251 lower blood sugar over time. Participants will be randomly assigned to receive either UBT251, UBT251 placebo, semaglutide, or semaglutide placebo. All treatments are given once weekly by injection under the skin. The study follows participants over several weeks, measuring effects at weeks 16, 28, and 40, focusing on blood sugar control and body weight changes. Throughout the study, participants will have regular assessments including blood tests to measure glycated hemoglobin HbA1c, insulin resistance, beta-cell function, fasting glucose, body measurements, blood pressure, cholesterol levels, and other health markers. Safety is monitored by tracking any adverse events, with total participation lasting up to 40 weeks of treatment plus additional safety follow-up.

This study aims to collect prospective safety and effectiveness data for the C-Brace System, a microprocessor-controlled knee ankle foot orthosis, following standard care practices. The research focuses on patients with lower extremity pareses who are fitted with the C-Brace device. The goal is to better understand how the C-Brace influences walking speed, balance, risk of falling, and confidence in balance over time. The C-Brace is a custom-made device with thigh, calf, and foot components connected by an ankle joint or spring element. It uses sensors to continuously monitor knee joint movement and walking phases, adjusting hydraulic resistance and knee motion accordingly. Patients enrolled in the registry will undergo baseline evaluation, fitting, training or therapy sessions, and follow-up visits at 6, 12, 24, and 36 months after fitting. Participants will be assessed through various tests including timed walk tests, balance confidence scores, and mobility assessments at different intervals. The study also tracks falls related to device use and changes in activity levels with an activity tracker. Data collected will help characterize the safety and functional impact of the C-Brace over three years of follow-up.

Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

Researchers are evaluating a treatment approach for early-stage hormone-sensitive, HER-2 negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial compares breast conservation surgery with endocrine therapy alone against breast conservation surgery with both radiation and endocrine therapy. The goal is to see if skipping radiation after lumpectomy is not worse in preventing cancer recurrence in the same breast. Participants will be randomly assigned to one of two groups. One group will receive radiation therapy to the breast plus at least five years of endocrine therapy with drugs such as Tamoxifen, Anastrozole, Letrozole, or Exemestane. The other group will receive endocrine therapy only for at least five years without radiation. Radiation must start within 12 weeks of surgery if assigned. Endocrine therapy dosing and schedule are determined by the treating doctor. During the study, participants will have regular follow-ups up to five years to monitor cancer recurrence in the breast and elsewhere, survival, and breast preservation. Assessments will include clinical exams, imaging like mammograms or MRI, and pathology reviews. The main outcome is time to invasive or noninvasive breast tumor recurrence within five years. Some measures will continue through an average of 15 years, including breast conservation rates. Safety and overall health will be monitored throughout and after treatment.

Researchers are evaluating the safety and effectiveness of the Edwards PASCAL Transcatheter Valve Repair System in patients with symptomatic severe tricuspid regurgitation who are at intermediate or higher risk of death from tricuspid valve surgery. This prospective, multicenter, randomized, controlled pivotal trial compares transcatheter tricuspid valve repair plus optimal medical therapy OMT to OMT alone. The study aims to improve outcomes in patients with severe tricuspid valve disease through this novel treatment approach. Participants will be randomly assigned to receive either the Edwards PASCAL transcatheter valve repair system combined with OMT or OMT alone. Some patients who are not eligible for randomization may still receive the Edwards PASCAL system with OMT in single-arm or continued access study groups. Follow-up visits will be conducted at hospital discharge, 30 days, 3 months, 6 months, and annually up to 5 years to monitor progress and outcomes. During the study, participants will undergo assessments including quality of life questionnaires, heart function measurements, and monitoring for events such as mortality, heart failure hospitalizations, and need for additional heart interventions. Researchers will track changes in tricuspid regurgitation severity and right ventricular size, as well as major adverse events. The primary outcome focuses on a composite of mortality, heart device implantation or transplant, valve interventions, hospitalizations, and quality of life improvements at 6 months. Safety and effectiveness will be evaluated throughout the study duration, which may last up to 12 years.

Researchers are studying the long-term effects of aleniglipron, taken once daily, in adults with obesity or overweight who also have weight-related health problems. This Phase 3 global, randomized, placebo-controlled, and double-blind trial aims to evaluate how well aleniglipron works, how safe it is, and how well patients tolerate it over at least 76 weeks. The study also compares aleniglipron with placebo in terms of body weight changes, blood pressure, lipid levels, and patient-reported outcomes. Participants will be randomly assigned to receive one of three doses of aleniglipron or a placebo, all taken orally once daily. Along with the medication, all participants will follow a reduced-calorie diet and increase physical activity. The treatment phase lasts at least 76 weeks, during which effects on weight and other health measures will be assessed. During the study, participants will undergo assessments of body weight, waist size, blood pressure, cholesterol, blood sugar, and quality of life measures from the start through week 76. Researchers will monitor safety and tolerability throughout the treatment period. This long-term study will help understand the impact of aleniglipron on weight management and related health factors over more than a year of treatment.

Researchers are evaluating the long-term effects of maridebart cafraglutide in adults with obesity or overweight. This extension study follows participants from a previous trial to assess the medications ongoing efficacy, safety, and tolerability over an extended period. The trial is designed as a phase 3 randomized and double-blind study to provide comprehensive information on treatment outcomes. Participants will receive different doses of maridebart cafraglutide administered by subcutaneous injection at varying intervals, including once every 4, 8, or 12 weeks. Some participants who received placebo or lower doses in the previous trial will undergo dose escalation or re-randomization to different dose groups or placebo. The study includes a dose-escalation phase for certain participants before initiating the assigned high dose. During the study, participants will be regularly monitored for changes in body weight compared to the original trial baseline, treatment-emergent adverse events, and serious adverse events. Additional assessments will track waist circumference, quality of life related to weight, and maintenance of weight loss. Participants are expected to complete visits and evaluations over approximately 48 weeks, with safety data collected up to 60 weeks from the start of the extension trial.

Researchers are studying how well inotuzumab ozogamicin works when combined with frontline chemotherapy in treating young adults aged 18 to 39 years with newly diagnosed B acute lymphoblastic leukemia that is CD22 positive. This phase III trial investigates the side effects and effectiveness of this combination compared to chemotherapy alone, aiming to improve event-free survival and other outcomes. The study also explores genetic and molecular markers to better understand treatment response and risks. Participants receive a pediatric-inspired chemotherapy regimen called CALGB 10403, which includes multiple courses of treatment remission induction, remission consolidation, interim maintenance, delayed intensification, and maintenance therapy. Some patients also receive inotuzumab ozogamicin intravenously on specific days, followed by blinatumomab if minimal residual disease is detected. Treatment cycles repeat according to response and tolerance, with additional therapies like rituximab and radiation as needed. Imaging and laboratory tests are done throughout. During the trial, participants undergo regular assessments including bone marrow biopsies, blood tests, and imaging such as echocardiography or multigated acquisition scans. Researchers measure outcomes like event-free survival, disease-free survival, overall survival, response rates, and treatment side effects for up to 10 years. After treatment, patients are followed closely every few months for up to 10 years to monitor long-term effects and disease status.

Researchers are evaluating the effects of lenalidomide and dexamethasone with or without daratumumab in treating patients with high-risk smoldering multiple myeloma. This phase III trial aims to compare overall survival, progression-free survival, response rates, and safety between these treatments. The study also explores patient-reported quality of life, treatment adherence, minimal residual disease status, and imaging associations during therapy. Participants are randomly assigned to one of two treatment groups. The first group receives daratumumab intravenously on a detailed schedule across up to 24 courses, plus oral lenalidomide daily for 21 days and dexamethasone on specific days during the first 12 courses. The second group receives only oral lenalidomide and dexamethasone on a similar schedule for up to 24 courses. Treatment cycles repeat every 28 days unless disease progression or unacceptable side effects occur. During the study, participants complete quality-of-life questionnaires and undergo laboratory tests, including minimal residual disease assessments and PETCT imaging. Safety is closely monitored, especially infusion-related reactions and toxicity. After treatment, patients are followed for up to 15 years with periodic visits every 3 to 12 months to track long-term outcomes and survival.
