Hypertension · Hypertension, Systolic · Hypertension, Essential
A prospective, multinational, randomized, double-blind, clinical trial evaluating the safety and effectiveness of a novel atrioventricular interval modulation (AVIM) algorithm downloaded into a dual-chamber Medtronic Astra/Azure pacemaker.
Smoldering Plasma Cell Myeloma
This phase III trial studies how well lenalidomide and dexamethasone works with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma.
Aortic Stenosis · Coronary Artery Disease · Coronary Stenosis
Patients undergoing transcatheter aortic valve replacement (TAVR) often have concomitant coronary artery disease (CAD) which may adversely affect prognosis. There is uncertainty about the benefits and the optimal timing of revascularization for such patients. There is currently clinical equipoise regarding the management of concomitant CAD in patients undergoing TAVR. Some centers perform routine revascularization with percutaneous coronary intervention (PCI) (either before or after TAVR), while others follow an alternative strategy of medical management. The potential benefits and optimal timing of PCI in these patients are unknown. As TAVR expands to lower risk patients, and potentially becomes the preferred therapy for the majority of patients with severe aortic stenosis, the optimal management of concomitant coronary artery disease will be of increasing importance. The COMPLETE TAVR study will determine whether, on a background of guideline-directed medical therapy, a strategy of complete revascularization involving staged PCI using drug eluting stents to treat all suitable coronary artery lesions is superior to a strategy of medical therapy alone in reducing the composite outcome of Cardiovascular Death, new Myocardial Infarction, Ischemia-driven Revascularization or Hospitalization for Unstable Angina or Heart Failure. The study will be a randomized, multicenter, open-label trial with blinded adjudication of outcomes. Patients will be screened and consented for elective transfemoral TAVR and randomized within 96 hours of successful balloon expandable TAVR. Complete Revascularization: Staged PCI using third generation drug eluting stents to treat all suitable coronary artery lesions in vessels that are at least 2.5 mm in diameter and that are amenable to treatment with PCI and have a ≥70% visual angiographic diameter stenosis. Staged PCI can occur any time from 1 to 45 days post successful transfemoral TAVR. Vs. Medical Therapy Alone: No further revascularization of coronary artery lesions. All patients, regardless of randomized treatment allocation, will receive guideline-directed medical therapy consisting of risk factor modification and use of evidence-based therapies. The COMPLETE TAVR study will help address the current lack of evidence in this area. It will likely impact both the global delivery of health care and the management and clinical outcomes of all patients undergoing TAVR with concomitant CAD.
Systemic Lupus Erythematosus · Antiphospholipid Syndrome
The PROMISSE Study is an observational study of 700 pregnant patients, enrolled at nine major clinical centers. The purpose of the study is 1) to determine whether certain proteins (called complement split products) that can injure healthy organs can be used to predict poor pregnancy outcome in patients with systemic lupus erythematosus (SLE) and anti-phospholipid syndrome (APS), and/or 2) to determine whether elevated levels of circulating antiangiogenic factors predict pregnancy complications in patients with aPL antibodies and/or SLE.
Generalized Anxiety Disorder (GAD)
Generalized anxiety disorder (GAD) is usually treated with antidepressant therapy (ADT); however, sometimes ADTs alone are not enough to adequately treat GAD. The purpose of this study is to assess how safe and effective ABBV-932 is when added to the antidepressant therapies in adult participants with GAD who have had an inadequate response ADTs. ABBV-932 is an investigational drug being developed for the adjunctive treatment of GAD. Participants will be randomly assigned to receive ABBV-932 or Placebo in addition to their currently prescribed ADTs. There is 1 in 3 chance of participants assigned to Placebo. Approximately 315 adult participants with GAD and inadequate response to ADTs will be enrolled in approximately 50 sites in the United States and Puerto Rico. Participants will receive oral capsules of ABBV-932 or matching placebo in addition to their prescribed ADT for 6 weeks and then will be followed for an additional 4 week follow-up period. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
Hemophilia A With Inhibitor · Hemophilia B With Inhibitor
Phase IV multi-center, US-centric, open-label, safety study enrolling participants with Hemophilia A or B with inhibitors, 12 years of age and older, who are either on long term prophylactic treatment (e.g., emicizumab) at risk of experiencing a breakthrough bleeding event (BE), or who are not on prophylactic treatment who may need to control a BE.
Acute Myeloid Leukemia
This phase II MyeloMATCH treatment trial studies how well ASTX727 and venetoclax plus enasidenib works compared to ASTX727 and venetoclax alone for the treatment of older patients with newly diagnosed acute myeloid leukemia (AML) or younger patients who are considered unfit for standard treatment, and who have an abnormal change (mutation) in the IDH2 gene. This gene mutation can cause AML to grow and spread. This trial is being done to see if adding enasidenib to the usual treatment can help more patients with the IDH2 gene get rid of AML. ASTX727 is a fixed-dose formulation of two drugs, cedazuridine and decitabine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have a greater effect. Decitabine is in a class of medications called hypomethylation agents. It works by helping the bone marrow produce normal blood cells and by killing abnormal cells in the bone marrow. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Enasidenib works by stopping the growth and spread of tumor cells that have the IDH2 mutation. Giving ASTX727 and venetoclax plus enasidenib may work better in treating AML patients with the IDH2 mutation.
Overweight , Obesity · Adults
A study of ALV-100 to assess efficacy, safety and tolerability among participants with overweight or obesity who have previously achieved a body weight reduction of ≥10% while treated with incretin-based therapies.
Chickenpox
The purpose of this study is to assess the consistency of immune response to three different lots of GSK's investigational varicella vaccine (VNS Vaccine), and to compare the safety and immune response of VNS vaccine to an already approved varicella vaccine (VV) known as Varivax. The study will be conducted in healthy children aged 12 to 15 months, who have neither contracted varicella nor received a varicella vaccination.
Ovarian Cancer
The goal of this clinical research study is to find out if combining a standard blood test (CA-125) that checks for ovarian cancer with other blood tests that check for related tumor markers may be helpful in the early detection of ovarian cancer in women who are at low risk. Tumor markers are substances in the blood that may be related to ovarian cancer.
Sepsis · Length of Stay · Mortality
Study Hypothesis/Question In infants born very preterm, advancing enteral feeds after 24 hours from birth (limited trophic feeds) versus after 72 hours (extended trophic feeds) reduces the risk of all-cause late onset sepsis (LOS) without increasing the risk of other adverse outcomes. Study Design Type This is a multi-center, open-label, parallel-group, individual randomized controlled trial comparing two different trophic feeding regimens in preterm infants born between 25w0d and 31w6d. These infants will be randomly assigned to either the intervention group, receiving limited trophic feeding (20 to 25 mL/kg/day for one day) or the control group, receiving extended trophic feeding (20 to 25 mL/kg/day for three days) prior to advancing enteral feeds until full feeding volume (140 mL/kg/day) is achieved. Eligibility Criteria Preterm infants with gestational ages between 25 0/7 and 31 6/7 weeks and a birthweight of \<1500 grams who are admitted to six participating neonatal units will be eligible for inclusion. Infants with \<5th percentile for weight at birth, vasopressor use within first 24 hours of life major congenital/genetic anomalies affecting enteral feeding, growth, or mortality, and those with a terminal illness in which decisions to withhold or limit support have been made will be excluded. Infants of parents or legal guardians who are unable to provide consent within 36 hours of birth will also be excluded. Study Intervention/Methods Written parental informed consent will be obtained prenatally or within the first 36 hours of birth. Infants will be randomized to receive limited trophic feeds of 24 to 36 hours or extended trophic feeds for 72 hours prior to the advancement of enteral feeds. Infants will be fed parent's own milk (POM) with donor human milk as the alternative if POM is unavailable. Primary Outcome Late-onset sepsis, defined as positive blood, urine, and/or cerebrospinal fluid (CSF) cultures in the presence of compatible clinical signs of sepsis, occurring after postnatal day 3 and before hospital discharge, and treated with antibiotics for 5 days or more. Secondary Outcome(s) The trial will assess various secondary outcomes including length of hospital stay, all-cause in-hospital mortality, duration of IV fluids and central line utilization, necrotizing enterocolitis (Bell's stage IIa or higher), severe intraventricular hemorrhage (grade III or IV either unilaterally or bilaterally), bronchopulmonary dysplasia (oxygen requirement or positive pressure ventilation at 36 weeks corrected gestational age), or retinopathy of prematurity requiring intervention. Additionally, growth metrics throughout hospitalization will be evaluated using change in weight, length, and head circumference z-scores from birth to 36 weeks' corrected gestational age between infants in the limited and extended trophic feeding groups. We will also evaluate the 2 year developmental outcomes of a subset of participants who consent to follow up. This will include the Bayley Scales of Infant and Toddler Development-4th edition Language, Cognitive, and Motor domain scores at 2 years corrected age.
Uterine Leiomyosarcoma
This is a clinical trial to test letrozole in patients with uterine leiomyosarcoma. The main question is will treatment with letrozole extend progression-free survival in patients. Patients will receive 2/5 mg of letrozole daily.
Basal Ganglia Germinoma · Diabetes Insipidus · Germinoma
This phase II trial studies how well lower dose radiotherapy after chemotherapy (Carboplatin \& Etoposide) works in treating children with central nervous system (CNS) germinomas. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Researchers want to see if lowering the dose of standard radiotherapy (RT) after chemotherapy can help get rid of CNS germinomas with fewer long-term side effects.
Prostate Adenocarcinoma · Stage III Prostate Cancer AJCC v8 · Stage IVA Prostate Cancer AJCC v8
This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.
Astrocytoma, IDH-Mutant, Grade 3
This phase III trial compares the effect of vorasidenib to placebo in combination with usual treatment, temozolomide, in treating patients with newly diagnosed grade 3 astrocytoma after radiation. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid and may kill tumor cells and slow down or stop tumor growth. Vorasidenib citrate blocks the proteins made by the mutated IDH1 and IDH2 genes, which may help keep tumor cells from growing. It is a type of enzyme inhibitor and a type of targeted therapy. Adding vorasidenib to the usual treatment, temozolomide, may be more effective than temozolomide alone in treating patients with newly diagnosed grade 3 astrocytoma after radiation therapy.
Endometrial Cancer
This is a Phase IB/II multi-cohort study designed to evaluate the efficacy and safety of targeted agents with or without cancer immune checkpoint therapy with atezolizumab in participant with recurrent and/or persistent endometrial cancer. The main protocol provides a platform for genomic screening with homogeneous basic eligibility criteria in order to direct study participants into biomarker-matched study cohorts consisting of testing targeted agents.
Grade 3b Follicular Lymphoma · High Grade B-Cell Lymphoma · High Grade B-Cell Lymphoma With MYC and BCL2 and/or BCL6 Rearrangements
This phase 2 trial studies the side effects and best dose of tazemetostat and zanubrutinib in combination with tafasitamab and lenalidomide, and to see how well these combinations work in treating patients with large B-cell lymphoma that returned or did not respond to earlier treatment. Tazemetostat is in a class of medications called EZH2 inhibitors. It helps to stop the spread of cancer cells. Zanubrutinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells. tafasitamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Lenalidomide is in a class of medications called immunomodulatory agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells in the bone marrow. The addition of tazemetostat or zanubrutinib to tafasitamab and lenalidomide may be able to shrink the cancer or extend the time without cancer symptoms coming back.
