Active clinical trials for "Recurrence"

This phase I/II trial studies the side effects and how well BGB-290 and temozolomide work in treating patients with gliomas (brain tumors) with IDH1/2 mutations that have come back. BGB-290 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, 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. Giving BGB-290 and temozolomide may work better in treating patients with recurrent gliomas.

Patients with atrial fibrillation (AF) who have had a prior stroke are at very high risk of recurrent ischemic stroke. About 40% of these strokes are due to large emboli which result in large cerebral vessel occlusion (LVO). This randomized control trial aims to address this unmet need by testing whether use of bilateral carotid filter implants in addition to OAC will reduce the risk of stroke in AF patients with recent (e.g. within 12 months) ischemic stroke vs. only OAC.

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.

Crohn's disease (CD) is a chronic recurrent intestinal inflammation involving the whole digestive tract, with high disability rate, high surgical rate and high recurrent rate postoperatively. Preventing postoperative recurrence in CD patients is an important clinical problem needed urgent intervention. Azathioprine (AZA) and infliximab (IFX) effectively prevent postoperative recurrence in CD patients, but the postoperative recurrence rate is still as high as 41%. Oral supplement of n-3 polyunsaturated fatty acids (n-3 PUFA) owns the advantages of high compliance and low economic cost. We aim to evaluate the effect of routine treatment (AZA/IFX) combined with long-term dietary n-3PUFA on the prevention and treatment of postoperative recurrence of CD, which help optimize the treatment strategy for the prevention of postoperative recurrence.

This phase I trial studies the side effects and best dose of venetoclax when given together with lenalidomide and rituximab hyaluronidase in treating patients with follicular lymphoma and marginal zone lymphoma that has come back after treatment (relapsed) or has not responded to treatment (refractory). Venetoclax may stop the growth of cancer cells by blocking the action of a protein called Bcl-2, that helps cancer cells survive. Immunotherapy with lenalidomide, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as rituximab and rituximab hyaluronidase, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this research is to determine if the combination of three drugs, venetoclax, lenalidomide, and rituximab hyaluronidase are safe to administer in patients whose low-grade lymphoma (follicular or marginal zone) has come back after initial therapy or was not responsive to initial therapy.

Human papillomavirus (HPV) is the most common sexually transmitted infection (STI) worldwide. Infection by certain high-risk oncogenic types of HPV (HR-HPV) is the major cause of several cancers in men, notably squamous cell carcinoma (SCC) of the anal canal. Rates of anal infection with these HR-HPV strains, and the resultant high-grade anal dysplasia and anal cancer are much higher in men who have sex with men (MSM) than in the general population. Co-infection with human immunodeficiency virus (HIV) further amplifies this burden, making the rates of anal SCC in HIV-positive MSM higher than the historic rates of cervical cancer prior to the adoption of routine cervical cytology screening. Despite these alarming statistics, there are no established protocols for optimal screening and treatment of anal HPV and cancer precursors, nor has there been any widespread rollout of organized screening programs anywhere in Canada. Further, not only does HPV directly cause significant disease in these men, but there is growing epidemiologic evidence that HPV infection may enhance sexual transmission of HIV. These significant knowledge gaps translate into fundamental deficiencies in care for HIV-positive MSM. The HPV Screening and Vaccine Evaluation in MSM (HPV-SAVE) study team was funded by the Canadian Institutes of Health Research (CIHR) via its Boys' and Men's Health Team Grant Competition. It aims to recruit a large group of MSM from various Ontario and Vancouver clinics, in order to carry out a number of different studies. The HPV-SAVE team brings together community and internationally-recognized experts in HPV and HIV disease and mucosal immunology, to better define the optimal approaches for primary and secondary prevention and treatment of HPV-associated anal disease among HIV-positive MSM, and to explore biological mechanistic evidence regarding the potential role of HPV as a co-factor for HIV transmission. This will yield critical information which can lead to improvement in the health of MSM, and will provide a foundation on which to build large-scale screening and treatment trials on a national level. A key part of this research program involves an analysis of the potential role played by the HPV vaccine in the overall management of HIV-positive MSM. Planned vaccine-related projects include: A mixed-methods analysis of the knowledge, attitudes, and acceptability of HPV vaccination amongst HIV-positive MSM, through quantitative (e.g. cross-sectional survey) and qualitative (e.g. in-depth interviews) means. A comprehensive assessment of the 9-valent HPV vaccine in HIV-positive MSM, including safety and immunogenicity, as well as its potential role in secondary prevention of high-grade anal dysplasia. This is the study on which the current proposal is based.

Transcatheter left atrial antral ablation, aiming at complete electrical isolation of the pulmonary veins (PVI), has become mainstay in atrial fibrillation (AF) treatment. This approach has been proved superior to medical rhytmh control strategy in maintaining sinus rhythm. Moreover PVI has been associated with significant survival benefit in patients with heart failure and reduced left ventricular ejection fraction. Nevertheless, despite progress in the field of catheter ablation, recurrence rates remain high. Inhibitors of type 2 sodium- glucose co-transporter (SGLT2i) is a relatively recent addition to the array of anti-diabetic agents, becoming part of everyday clinical practice. However, although SGLT2i were first used solely as antidiabetics because of their glycosuric effect, further research demonstrated that these drugs may independently reduce cardiovascular events, especially in patients with heart failure, a benefit that was consistent among diabetic and non-diabetic patients. Moreover, pleiotropic effects have been observed, including a reno-protective action. These findings suggest that SGLT2i mechanisms of action extend beyond the obvious increase in urinary sodium and glucose excretion. Various studies propose that these drugs promote favourable metabolic changes in myocardial energetics, while they also inhibit inflamation and sympathetic activation, resulting in restriction of induced fibrosis and structural remodeling, which are key elements in atrial fibrillation generation and maintenance. These findings suggest that the use of SGLT2i could offer antiarrhythmic benefit by reducing and/or reversing structural and electrical remodeling, leading to the assumption that use of theese drugs could reduce recurrences after transcatheter AF ablation.

This study is intend to explore the efficacy and safety of combined treatment of camrelizumab and bevacizumab in adult patients with recurrent glioblastoma.

The goal of this randomized controlled trial is to To assess the effectiveness of intermittent bladder catheterization (IBC) in reducing the recurrence of urethral stricture among females in tertiary care hospital, Lahore. All the patient who have undergone urethral dilation by urologist will be divided into two groups i.e. intervention group and control group. In control group already diagnosed cases of urethral stenosis who have undergone urethral dilatation will be followed fortnightly for AUA symptoms scoring for urinary complaints and urethral catheterization with nelton 14 Fr to exclude urethral stricture recurrence. In intervention group, researcher will explain the patient about the intermittent catheterization technique and give the practical demonstration for better patient understanding and make correction in patient's technique of intermittent bladder catheterization. Patient will be followed from the day of recruitment in the study after every 02 weeks by the researcher for 2 successive months. In every follow up session, assessment of the urinary complaints via AUA scoring, review of patient's technique of urethral catheterization in intervention group, and each patient's adherence to the intermittent bladder catheterization (IBC) will be noted.
