NCT03358472
The purpose of this study was to evaluate the efficacy and safety of pembrolizumab plus epacadostat, pembrolizumab monotherapy, and the EXTREME regimen (cetuximab + cisplatin or carboplatin + 5-fluorouracil) as first-line treatment for recurrent or metastatic head and neck squamous cell carcinoma (HNSCC).
NCT02312557
This phase II trial studies how well pembrolizumab works in treating patients with prostate cancer that has spread to other places in the body and keeps growing even when the amount of testosterone in the body is reduced to very low levels despite previous treatment with enzalutamide. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells.
NCT05595369
This study is a platform protocol designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This protocol is a prospective, multi-center, multi-arm, double-blind, randomized, controlled platform trial with different interventions organized as appendices to the protocol. Each appendix (or sub-study) evaluates potential mechanisms of action, efficacy, and safety of antivirals and other therapeutics in individuals with PASC, according to the platform protocol objectives. The hypothesis is that persistent viral infection, viral reactivation, and/or overactive/chronic immune response and inflammation are underlying contributors to PASC and that antiviral and other applicable therapies may result in viral clearance or decreased inflammation and improvement in PASC symptoms.
NCT05911360
The study aims at evaluating the maintenance of virologic suppression of dolutegravir/lamivudine (DTG/3TC) fixed dose combination (FDC) at Week 48 post-switch from bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in participants living with Human Immunodeficiency Virus Type 1 (HIV-1) who are of at least 50 years of age and above.
NCT02003222
This randomized phase III trial studies combination chemotherapy with blinatumomab to see how well it works compared to induction chemotherapy alone in treating patients with newly diagnosed breakpoint cluster region (BCR)-c-abl oncogene 1, non-receptor tyrosine kinase (ABL)-negative B lineage acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether combination chemotherapy is more effective with or without blinatumomab in treating newly diagnosed acute lymphoblastic leukemia.
NCT05492903
Home care workers (HCWs) are at-risk for chronic pain and associated problems, including emotional distress, opioid use and misuse, and work-related disability. To address these issues, the proposed study will adapt an established peer-led and supportive group program to address the needs of HCWs with chronic pain. The new program, named COMPASS for Navigating Pain (COMPASS-NP), will integrate work-based injury protections with pain education and cognitive-behavioral therapy strategies for pain self-management in order to reduce pain interference with HCWs' work and life, and advance their safety, health, and well-being.
NCT03730792
The project is a cluster randomized controlled trial of an occupational health intervention for newly hired bus operators. Transit authorities will be randomized to intervention and usual practice conditions and new bus operators will be recruited to participate in a two year study. Intervention participants will complete a program designed to prevent weight gain while also supporting early adjustment and job success. Control participants will experience standard or usual practice working conditions.
NCT00098475
This randomized phase III trial studies lenalidomide and low-dose dexamethasone to see how well it works compared to lenalidomide and standard-dose dexamethasone, given with or without thalidomide, in treating patients with multiple myeloma. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Lenalidomide and thalidomide may also stop the growth of multiple myeloma by blocking blood flow to the cancer. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide, thalidomide, and dexamethasone together may kill more cancer cells.
NCT02048813
This phase III trial studies ibrutinib and rituximab to see how well they work compared to fludarabine phosphate, cyclophosphamide, and rituximab in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. It is not yet known whether fludarabine phosphate, cyclophosphamide, and rituximab may work better than ibrutinib and rituximab in treating patients with untreated chronic lymphocytic leukemia or small lymphocytic lymphoma.
NCT05013229
This study will compare the new medicine IcoSema, which is a combination of insulin icodec and semaglutide, taken once a week, to insulin glargine taken daily with insulin aspart in people with type 2 diabetes.The study will look at how well IcoSema controls blood sugar level in people with type 2 diabetes compared to insulin glargine taken with insulin aspart. Participants will either get IcoSema or insulin glargine taken with insulin aspart. Which treatment participants get is decided by chance. IcoSema is a new medicine that doctors cannot prescribe. Doctors can already prescribe insulin glargine and insulin aspart in many countries. Participants will get IcoSema or insulin glargine together with insulin aspart. Participants must inject IcoSema once a week or inject insulin glargine once daily and insulin aspart 2-4 times a day. Participants will inject the medicines with a pen, which has a small needle, in a skin fold in the thigh, upper arm, or stomach. The study will last for about 1 year and 1 month. Participants will be asked to wear a sensor that measures participants blood sugar level all the time during an 8 week period at the beginning of the study and a 4 week period at the end of the study. Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period.
NCT06420297
To evaluate long-term safety and tolerability of carbetocin nasal spray (3.2 mg TID) in subjects with PWS
NCT02091245
This research study involves participants who have acute lymphoblastic or acute myelogenous leukemia that has relapsed or has become resistant (or refractory) to standard therapies. This research study is evaluating a drug called KPT-330. Laboratory and other studies suggest that the study drug, KPT-330, may prevent leukemia cells from growing and may lead to the destruction of leukemia cells. It is thought that KPT-330 activates cellular processes that increase the death of leukemia cells. The main goal of this study is to evaluate the side effects of KPT-330 when it is administered to children and adolescents with relapsed or refractory leukemia.
NCT03391466
The goal of this clinical study is to assess whether axicabtagene ciloleucel therapy improves the clinical outcome compared with standard of care second-line therapy in participants with relapsed/refractory diffuse large B-cell lymphoma (DLBCL).
NCT06613100

The primary objectives are to determine the objective response rate (ORR) established by the confirmed best overall response (BOR) following intratumoral administration of DaRT - Diffusing Alpha-Emitters Radiation Therapy, as well as to assess the Duration of Response (DOR) 6 months from initial response. Secondary objectives are to assess the safety of DaRT, and to assess the progression free survival (PFS), overall survival (OS), Overall Duration of Response (O-DOR), local control and quality of life (QOL) for patients treated with DaRT.
NCT04008706
This is a global, Phase IIIb, multicenter, open-label, single-arm study to evaluate the safety and efficacy of acalabrutinib 100 mg twice daily (bid) in approximately 540 participants with chronic lymphocytic leukemia (CLL). Participants will be enrolled into 3 following cohorts: treatment-naive (TN), relapsed/refractory (R/R), and prior ibrutinib therapy. For this study, participants in the UK will be enrolled ONLY into the R/R cohort or the prior ibrutinib cohort. Participants in the US will be enrolled ONLY into the TN or R/R cohort. Participants will remain on study intervention until completion of 48 cycles (28 days per cycle), or until study intervention discontinuation due to, for example disease progression, or toxicity, withdrawal of consent, loss to follow-up, death, or study termination by the sponsor whichever occurs first. The duration of the study will be approximately 72 months from the first participant enrolled. This duration includes an estimated 24-month recruitment time and an assumed 48 cycles of study intervention (28 days per cycle); additional study time will be accrued during the Disease Follow up period for those participants remaining on study intervention after completion of 48 cycles prior to the final data cutoff (DCO) (the amount of time will vary by participant).
NCT04624477
This is a prospective, observational, multi-center study examining the long-term outcomes of patients with small, low risk papillary thyroid cancer who offered the choice of active surveillance (close follow-up to monitor for potential disease progression) or immediate surgery.
NCT05274750
This study will evaluate the efficacy and safety of depemokimab (GSK3511294) in participants with Chronic rhinosinusitis with nasal polyps (CRSwNP).
NCT05823948
This study looks at how a person with type 2 diabetes can be treated with insulin icodec and a flash glucose monitor (a small sensor inserted under the skin to measure blood sugar all the time). The study will look at how well insulin icodec controls blood sugar when used in combination with a flash glucose monitor. Participants will get insulin icodec that they have to inject once a week on the same day of the week. The insulin will be injected with a needle in a skin fold in the thigh, upper arm, or stomach. The study will last for about 8 months. Participants will have to wear a flash glucose monitor throughout the study. This is a sensor that fits on arm. Participants will be asked to use a commercially available app called LibreView to allow team to view flash glucose monitor data. Participants will get a study phone to scan the flash glucose monitor 4 times daily and they will be able to see all of the flash glucose monitor data during the study. Women cannot take part if pregnant, breast-feeding or planning to get pregnant during the study period.
