Filter by:This phase II trial studies how well T-DMI with or without abemaciclib works for the treatment of HER2-positive breast cancer that has spread to other places in the body (metastatic). T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called DM1. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers DM1 to kill them. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and abemaciclib may work better in treating patients with breast cancer compared to T-DM1 alone.
The Coronavirus Disease 2019 (COVID-19) pandemic has placed tremendous stress on the global economy since its outbreak in December 2019. Currently, with nearly 1.3 million confirmed cases, there is still no effective way to contain the disease. The transmission of COVID-19 occurs via direct (prolonged close interaction, within 2 meters for more than 30 minutes) and indirect (fomites) contacts. Locally, the risk of COVID-19 infection in household contacts of confirmed cases is about 4%. These at-risk individuals are identified through contact tracing and infectious may be preventable using post-exposure-prophylaxis (PEP). However, there has yet to be a single effective, safe, and affordable pharmacological agent with such capabilities. Hydroxychloroquine (HCQ) is a cheap anti-malarial and immunomodulatory agent which may potentially be used as PEP against COVID-19. HCQ is capable of blocking the invasion and intracellular replication of the virus. Existing studies have reported efficacy of HCQ in treating COVID-19, with reduced time to clinical recovery and few reports of patients suffering from significant side effects. However, existing studies are largely limited by their small sample sizes. Furthermore, there has yet to be a published trial on HCQ's role in PEP. This cluster randomized trial will evaluate the safety and efficacy of oral HCQ PEP, taken over for 5 days, in reducing the number of infected household contacts of confirmed COVID-19 patients under home quarantine. Comparison will be made between HCQ PEP (treatment group) and no treatment (control group). Subjects will be followed up over a course of 28 days, with daily symptom monitoring conducted over phone calls. Positive outcomes from this study will provide a means for us to battle the COVID-19 pandemic.
The Purpose of this study is to compare two programming modalities for CRT devices in Heart Failure patients with an indication for Cardiac Resynchronization Therapy
The investigators plan to evaluate a strategy of chemoprophylaxis with hydroxyloquine (HCQ) against COVID-19 infection in patients diagnosed with an immunomediated inflammatory disease who are following a treatment with biological agents and / or Jak inhibitors. The strategy will be carried out through a randomised double blind, placebo-controlled clinical trial and will assess comparative rates of infection (prevalence, incidence), severity including mortality, impact on clínical course of the primary diseases and toxicity. Such evaluation will require prospective surveillance to assess the different end-points. Drug interventions in this protocol will follow the Spanish law about off-label use of medicines.
The aim of this study is to clinically and radiographically compare the success and survival of implants immediately placed in molar fresh extraction socket to delayed implant placement at least 12 weeks post molar extraction. The secondary aim is to evaluate the peri-implant tissue response around implants with immediate vs. delayed placement.
The purpose of this study is to determine whether Urinary Kallikrein has an additional effect on enhancing collateral circulation in symptomatic intracranial atherosclerotic patients under clopidogrel and aspirin dual antiplatelet therapy.
An incidental gallbladder carcinoma is detected in approximately 0.2% of the cholecystectomy specimens removed for presumed benign disease. In patients that meet specific criteria, a surgical re-operation is recommended to treat possible residual tumor disease not treated with the initial cholecystectomy. The presence of residual disease in the re-intervention specimen worsens the prognosis of patient survival, according to several published series. Patients with known or high-risk of residual disease may benefit from a specific strategy that would improve patient selection before attempting re-resection. A pathology-based score has been developed but has not been yet validated in an external series of patients. The use of pathological data from the initial cholecystectomy specimen could identify patients at risk of residual disease and aid in selecting a specific therapeutic strategy prior to attempting surgical re-exploration.
TARA is a Digital Behaviour Change Intervention (DBCI) for Individuals with COPD (IwCOPD), which has been designed using a Human-Centred Design (HCD) methodology. HCD involves, among other elements, members of the target audience in evaluations at multiple stages within the design process. This feasibility study is primarily designed to assess the acceptability of the DBCI test asset to the target audience. Acceptability as defined for the purpose of this study includes usability of the system, and perceived value and desirability to the end-user audience. As such, engagement in this context is deemed to mean the degree to which the test asset provides a usable, acceptable, desirable and valuable experience to its users during a time-limited trial.
We propose to carry out a large multicentric, multinational, randomized controlled trial with two phases (two sequential randomized controled trials) to answer two questions: 1) Should hospitalized patients with recently diagnosed OHS be discharged from the hospital on an auto-titratable NIV treatment until the diagnosis of OHS is confirmed in 3 months? 2) Is the long-term effectiveness of outpatient titrated CPAP non-inferior to titrated NIV in ambulatory patients with OHS 3 months after hospital discharge? Clinical practice, multicenter open-label controlled randomized clinical trial with preset allocation rate (1:1) with two parallel-groups conducted in centers from Spain, France, Portugal and USA. The study will have two phases with two randomizations. The first phase will be a superiority study and the second phase will be a non-inferiority study.
The purpose of this study is to evaluate, in patients presenting with out-of-hospital cardiac arrest (OHCA) by ventricular fibrillation, refractory to 3 external electric shocks, the efficacy of a direct intravenous injection of 20 mmol KCl on their survival at hospital arrival.
