NCT04729959
This phase II trial studies the best dose and effect of tocilizumab in combination with atezolizumab and stereotactic radiation therapy in treating glioblastoma patients whose tumor has come back after initial treatment (recurrent). Tocilizumab is a monoclonal antibody that binds to receptors for a protein called interleukin-6 (IL-6), which is made by white blood cells and other cells in the body as well as certain types of cancer. This may help lower the body's immune response and reduce inflammation. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Fractionated stereotactic radiation therapy uses special equipment to precisely deliver multiple, smaller doses of radiation spread over several treatment sessions to the tumor. The goal of this study is to change a tumor that is unresponsive to cancer therapy into a more responsive one. Therapy with fractionated stereotactic radiotherapy in combination with tocilizumab may suppress the inhibitory effect of immune cells surrounding the tumor and consequently allow an immunotherapy treatment by atezolizumab to activate the immune response against the tumor. Combination therapy with tocilizumab, atezolizumab and fractionated stereotactic radiation therapy may shrink or stabilize the cancer better than radiation therapy alone in patients with recurrent glioblastoma.
NCT06391697
The e-OPRA Implant System, is a further development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System. The e-OPRA Implant system is an implant system for direct skeletal anchorage of amputation prostheses. The added feature in the e-OPRA Implant system, is a bidirectional interface into the human body that allows permanent and reliable communication using implanted electrodes. These electrodes will provide long-term stable bioelectric signals for an improved control of the prosthetic limb. The Magnetic Bead Tracking System, which will be implanted and used in combination with the e-OPRA Implant system, is an investigational device that consists of pairs of magnetic beads, and a set of magnetic field sensors that measure and track the length of muscles and the speed at which they move in real-time. When the beads are implanted in muscle in the residual limb of an amputee, the muscle length signal is communicated to an investigational, robotic ankle-foot prosthesis. The purpose of the study is to evaluate the feasibility of a transtibial amputee with the e-OPRA Implant System and Magnetic Bead Tracking System exhibiting full neural control over a neuro-mechanical prosthetic system. A maximum of seven subjects will be enrolled. Each subject will undergo one or more surgeries where the e-OPRA Implant System and Magnetic Bead Tracking System will be implanted. The subjects will participate in follow-up sessions the last of which occurs approximately 24 months after the surgery. This is a prospective, non-randomized, uncontrolled study.
NCT03882073
The hypothesis of this research protocol is that the investigators will be able to redesign the manner in which upper limb amputations are performed so as to enable volitional control of next generation prosthetic devices and restore sensation and proprioception to the amputated limb. The investigators will test this hypothesis by performing modified above elbow or below elbow amputations in ten intervention patients, and compare their outcomes to ten control patients who have undergone tradition amputations at similar levels. The specific aims of the project are: 1. To define a standardized approach to the performance of a novel operative procedure for both below elbow (BEA) and above elbow amputations (AEA) 2. To measure the degree of volitional motor activation and excursion achievable in the residual limb constructs, and to determine the optimal configuration and design of such constructs 3. To describe the extent of proprioceptive feedback achievable through the employment of these modified surgical techniques 4. To validate the functional and somatosensory superiority of the proposed amputation technique over standard approaches to BEA and AEA 5. To develop a modified acute postoperative rehabilitation strategy suited to this new surgical approach This will be a phase I/pilot clinical trial to be performed over a three-year period as a collaborative initiative involving Brigham \& Women's Hospital/Brigham \& Women's Faulkner Hospital (BWH/BWFH), Walter Reed National Military Medical Center (WRNMMC), and the Massachusetts Institute of Technology (MIT). The investigators will plan to perform 6 of the 10 amputations at BWH/BWFH, and 4 of the amputations at WRNMMC.

Subjects in this study will be randomized to arm A or B at 1:1 ratio as follows: * Arm A (Serplulimab): Serplulimab + chemotherapy (carboplatin-etoposide) * Arm B (control): Atezolizumab + chemotherapy (carboplatin-etoposide)
NCT04497116
The primary purpose of this study is to define the maximum tolerated dose (MTD) and determine a recommended Phase 2 dose (RP2D) and schedule of orally-administered RP-3500 (camonsertib) alone or in combination with talazoparib, a PARP inhibitor, or Gemcitabine in patients with advanced solid tumors with ATR inhibitor-sensitizing mutations. This study will also evaluate the safety and tolerability of RP-3500 (camonsertib) alone or in combination with talazoparib or gemcitabine, examine both the pharmacokinetics (PK)and pharmacodynamics (PD)and investigate its anti-tumor activity in solid tumors.
NCT05901831
Researchers are looking for a better way to treat people with chronic kidney disease (CKD), a progressive decrease in the kidneys' ability to work properly, and type 1 diabetes. In people with type 1 diabetes, the body does not make enough of a hormone called insulin, resulting in high blood sugar levels that can cause damage to the kidneys. CKD often occurs together with or as a consequence of type 1 diabetes. The study treatment finerenone works by blocking certain proteins, called mineralocorticoid receptors. An increased stimulation of these proteins is thought to damage the kidneys and the heart. By lowering their stimulation, finerenone reduces the risk of kidney disease progressively getting worse. Finerenone is approved for doctors to prescribe to people with CKD and type 2 diabetes. In this study, researchers want to learn if finerenone works better than placebo in reducing the participants' kidney disease from getting worse when given in addition to standard of care (SOC) treatment. A placebo looks like a treatment but does not have any medicine in it. SOC is a procedure or treatment that medical experts consider most appropriate for a condition or disease. To find out how well finerenone works, the level of a protein (albumin) in the urine will be measured. Researchers also want to know how safe finerenone is. To do this, the researchers will collect the number of participants with: * medical problems (also called treatment-emergent adverse events (TEAEs)) * serious TEAEs. An TEAE is considered 'serious' when it leads to death, puts the participant's life at risk, requires hospitalization, causes disability, causes a baby being born with medical problems, or is medically important * higher than normal blood levels of potassium (hyperkalaemia). Depending on the treatment group, the participants will either take finerenone or placebo, Importantly, the participants will also continue to take their regular SOC medicines. The participants will be in the study for up to 7.5 months and will take the study treatments for 6 months. During the study, they will visit the study site at least 6 times. The study team will: * collect blood and urine samples * check the participants' vital signs such as blood pressure and heart rate * do a physical examination including height and weight * check the participants' heart health by using an electrocardiogram (ECG) * do pregnancy tests in women of childbearing potential
NCT05405426
TITRE - Trial of Indication-based Transfusion of Red Blood Cells in ECMO, is a multicenter, prospective, randomized clinical trial. The overarching goal of TITRE is to determine whether restricting red blood cell (RBC) transfusion according to an indication-based strategy for those with bleeding and/or deficit of tissue oxygen delivery, compared with transfusion based on center-specific hemoglobin or hematocrit thresholds, can reduce organ dysfunction and improve later neurodevelopment in critically ill children receiving Extracorporeal Membrane Oxygenation (ECMO) support.

NCT04445662
This community-based randomized controlled trial will test the effect of contingent financial rewards on smoking abstinence among homeless-experienced adult cigarette smokers. Participants will be recruited from 3 Boston Health Care for the Homeless Program locations: a shelter clinic, a day center clinic, and a medical center clinic. All participants will be offered a varenicline prescription and tobacco coaching. Incentive arm participants will receive escalating financial rewards for saliva cotinine levels \<30 ng/ml, assessed 10 times over 12 weeks. Embedded qualitative interviews will explore the mechanisms of on-treatment and post-treatment effects of financial incentives on smoking abstinence in the context of homelessness.
NCT07041281
The hypertensive disorders of pregnancy (preeclampsia and gestational hypertension) are associated with increased long-term maternal risk of developing cardiovascular disease. Recent evidence suggests that activation of the mineralocorticoid receptor promotes ongoing susceptibility to hypertension in women following hypertensive disorders of pregnancy. In addition, women with overweight/obesity are at increased risk for progression to chronic hypertension after experiencing hypertensive disorders of pregnancy. Among women with hypertensive disorders of pregnancy and pre-pregnancy overweight/obesity, the investigators will conduct a randomized trial to test the effect of pharmacologically blocking the mineralocorticoid receptor for three months after delivery on blood pressure and cardiac remodeling at nine months postpartum.
NCT04489225

NCT05866302
The study will have two separate patient cohorts: Cohort 1 will include patients with newly diagnosed chronic graft versus host disease (GVHD), whereas cohort 2 will include patients with newly diagnosed chronic lung disease (CLD). For cohort 1, the primary objective will be to characterize PRM metrics at the onset of chronic GVHD and determine if a PRM signature is present that will predict 1-year CLD free survival. For cohort 2, the primary objective will focus on characterizing PRM at the onset of CLD and determine if PRM can predict the trajectory in lung function decline in affected patients.
NCT03313999
This protocol will utilize the lymphedema indentometer, or durometer (a novel, noninvasive piece of equipment that measures skin elasticity), to better characterize disease progression in patients with lymphedema. Beth Israel Deaconess Medical Center patients who undergo treatment of lymphedema will be candidates for this noninvasive test. This device and the data it generates will help understand the incidence of lymphedema at Beth Israel Deaconess Medical Center compared to national data and the outcomes of surgical treatment of lymphedema.

NCT02959437
This is an open-label, Phase 1/2 study in subjects with advanced or metastatic solid tumors. The study has three separate treatment groups where separate epigenetic agents are evaluated with an immunotherapy combination. Treatment Group A will evaluate the DNA methyltransferase inhibitor azacitidine in combination with the programmed death receptor-1 (PD-1) inhibitor pembrolizumab and the indoleamine 2,3-dioxygenase (IDO-1) inhibitor epacadostat; Treatment Group B will evaluate the bromodomain and extra-terminal (BET) inhibitor INCB057643 with pembrolizumab and epacadostat; and Treatment Group C will evaluate the lysine-specific demethylase 1A (LSD1) inhibitor INCB059872 with pembrolizumab and epacadostat. The study will be divided into 2 parts (Part 1 and 2). Part 1 is a dose-escalation assessment to evaluate the safety and tolerability of the combination therapies. Once the recommended doses have been determined, subjects with previously treated NSCLC, microsatellite-stable colorectal cancer (CRC), head and neck squamous cell carcinoma, urothelial carcinoma, and melanoma will be enrolled into expansion cohorts in Part 2.
NCT05896163
The purpose of this study is to learn about the effects of two study medicines (maplirpacept \[PF-07901801\] and glofitamab) when given together for the treatment of diffuse large B-cell lymphoma (DLBCL) that is relapsed or is refractory. Relapsed means has returned after last treatment. Refractory means that it has not responded to last treatment. The two study medicines are given after a single dose of obinutuzumab which is the third study medicine. DLBCL is a type of non-Hodgkin lymphoma (NHL). NHL is a cancer of the lymphatic system. It develops when the body makes abnormal B lymphocytes. These lymphocytes are a type of white blood cell that normally help to fight infections. This study is seeking adult participants who: * Have histologically confirmed diagnosis of DLBCL * Have received at least two first lines of treatment for NHL. * Are unable or unwilling to undergo a stem cell transplant or CAR-T cell therapy. Stem cell transplant is a procedure in which a patient receives healthy blood-forming cells to replace their own stem cells that have been destroyed by treatment. A CAR-T therapy is a type of treatment in which a patient's T cells are changed in the laboratory so they will attack cancer cells. Everyone in this study will receive all three medicines at the study site by intravenous (IV) infusion which is given directly into a vein. The two study medicines (maplirpacept \[PF-07901801\] and glofitamab) will be given in 21-day cycles. At Cycle 0, participants will receive a single dose of obinutuzumab pre-treatment followed by two step-up doses of glofitamab. The combination of maplirpacept (PF-07901801) with glofitamab full dose will be administered for the first time at Cycle 1 Day 1. Maplirpacept (PF-07901801) will be given weekly for the first three cycles and then every three weeks. Glofitamab will be given every 3 weeks for approximately 9 months. Thereafter participants will continue to receive maplirpacept alone. Maplirpacept (PF-07901801) will be given at different doses to different participants. Everyone taking part will receive the same fixed doses of glofitamab and obinutuzumab studied in patients with DLBCL. The study will compare the experiences of people receiving different doses of maplirpacept (PF-07901801). This will help to determine what dose is safe and effective when given with the other 2 study medicines.
