NCT ID: NCT04870203 Recruiting - Clinical trials for Rheumatoid Arthritis

Combination of Baricitinib and Adalimumab in Rheumatoid Arthritis

Start date: July 15, 2021
Phase: Phase 3
Study type: Interventional

As stated by the European League Against Rheumatism (EULAR) and the Société Française de Rhumatologie (SFR), treatment of patients with rheumatoid arthritis (RA) should target sustained remission or at least low disease activity. However, despite significant advances based on various combinations of conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and biologic DMARDs, RA therapies meet treatment goals only in some patients: - 40 to 50% of patients with early RA, treated with methotrexate (MTX) monotherapy as first-line therapy, - 20 to 30% of patients treated with a combination of MTX and biologic as second-line therapy. - Less than 10% of patients treated with a combination of MTX and another targeted DMARD, such as baricitinib, as third-line therapy. Therefore, new strategies targeted at achieving a higher percentage of remission are needed, that do not require waiting for multiple failed therapies. Combinations of biologics have shown synergistic improvement of symptoms in murine models of RA relative to the improvement observed with either agent alone. However, in RA patients, only five randomised clinical trials (RCTs) have explored the efficacy and safety of combining tumour necrosis factor (TNF) inhibitor with another biologic (anakinra, abatacept, rituximab or bimekizumab). Baricitinib is a selective, reversible and competitive inhibitor of Janus kinases (Jaki). This treatment is efficient in a number of therapeutic scenarios in RA and showed a clinical superiority over adalimumab in one RCT (RA-BEAM study in MTX inadequate responders). Of note, baricitinib inhibits many of the pro-inflammatory cytokines involved in the pathogenesis of RA but does not block signalling downstream of TNF. Owing to the interest in combining different mechanisms of action, the investigators plan to assess the efficacy and safety of combination therapy with baricitinib and a TNF inhibitor (adalimumab). The investigators are aware that combining targeted therapies is not recommended due to a potential increase in the frequency of serious adverse events. However, several case series on patients treated with a combination of targeted therapies have been published, suggesting a certain efficacy in patients with refractory RA. The first ones focused on inflammatory bowel diseases and psoriasis, but more recently, combination of tofacitinib (which belongs to the same Jaki family as baricitinib) with various biologics has been reported in a sample of RA patients. No serious adverse effects were reported over a mean of approximately 11 months of therapy. The clinical improvement was mild but noticeable in these refractory RA cases. Recently, data of interest from the RA-BEAM study have been reported. Patients who switched from adalimumab to baricitinib showed improvements in disease control. Because the switch from adalimumab to baricitinib occurred without a washout period, and because adalimumab has a mean circulating half-life of approximately 14 days, patients would have received several weeks of dual TNF and Jak1/Jak2 inhibition in the course of the change of treatment. The observation of increased efficacy, with no apparent acute safety issues during the weeks when patients were exposed to both adalimumab and baricitinib, is of interest, and supports our strategy to combine the two treatments for patients with refractory RA. The investigators consider that there is a need for investigation into the addition of adalimumab to baricitinib in patients suffering of refractory RA (inadequate response to TNF inhibitors). The investigators hypothesize that in this population, based on ACR50 score, this combination therapy will decrease disease activity more efficiently than a switch to another targeted DMARD, such as baricitinib.

NCT ID: NCT04616846 Recruiting - Covid19 Clinical Trials

Thromboembolic Risk Screening in Patients With Cancer and COVID-19

Start date: August 4, 2020
Phase: N/A
Study type: Interventional

Study Rational Since December 2019, outbreak of COVID-19 caused by a novel virus SARS-Cov-2 has spread rapidly around the world and became a pandemic issue. First data report high mortality in severe patients with 30% death rate at 28 days. Exact proportions of the reasons of death are unclear: severe respiratory distress syndrome is mainly reported which can be related to massive cell destruction by the virus, bacterial surinfection, cardiomyopathy or pulmonary embolism. The exact proportion of all these causes is unknown and venous thromboembolism could be a major cause because of the massive inflammation reported during COVID-19. High levels of D-dimers and fibrin degradation products are associated with increased risk of mortality and some authors suggest a possible occurrence of venous thromboembolism (VTE) during COVID-19. Indeed, COVID-19 infected patients are likely at increased risk of VTE. In a multicenter retrospective cohort study from China, elevated D-dimers levels (>1g/L) were strongly associated with in-hospital death, even after multivariable adjustment. Also, interestingly,the prophylactic administration of anticoagulant treatment was associated with decreased mortality in a cohort of 449 patients, with a positive effect in patients with coagulopathy (sepsis-induced coagulopathy score ≥ 4) reducing the 28 days mortality rate (32.8% versus 52.4%, p=0.01). However the presence/prevalence of VTE disease is unknown in COVID-19 cancer patients with either mild or severe disease. Cancer patients are at a higher risk of VTE than general population (x6 times) and could be consequently at a further higher of VTE during COVID-19, in comparison with non-cancer patients. The exact rate of VTE and pulmonary embolism during COVID-19 was never evaluated, especially in cancer patients, and is of importance in order to understand if this disease needs appropriate prophylaxis against VTE. The largest series of cancer patients so far included 28 COVID-19 infected cancer patients: the rate of mortality was 28.6%. 78.6% of them needed oxygen therapy, 35.7% of them mechanical ventilation. Pulmonary embolism was suspected in some patients but not investigated due to the severity of the disease and renal insufficiency, reflecting the lack of data in this situation. The aim of the present study is to analyze the rate of symptomatic/occult VTE in a cohort of patients with cancer. Expected benefits Anticipated benefits of the research are the detection of VTE in order to treat it for the included patient. For all COVID-19 positive cancer patients it will enable to provide some guidelines and determine which patient are at risk for VTE and which will need ultrasound to detect occult VTE. Foreseeable risks Foreseeable risks for patients are non-significant because the additional procedures needed are ultrasound exam, and blood sample test. Methodology Retrospective and prospective (ambispective), multicentric study to evaluate the occurrence of venous thromboembolism during COVID-19 infection. Indeed, because the outbreak can end within the next 3-6 months, Investigators may not be able to answer the question if Investigators only focus on patients investigated prospectively. Investigators then decided to include patients from medical team who are already systemically screening patients with COVID-19 disease for VTE. Trial objectives Main objective To evaluate the rate of venous thromboembolism at 23 days during COVID-19 infection in cancer patients.

NCT ID: NCT04515446 Recruiting - Flu Clinical Trials

Quantification of Viral Load in the Upper Respiratory Tract in Patients Treated With Olsetamivir for Influenza

Start date: February 4, 2020
Phase: N/A
Study type: Interventional

Seasonal influenza is a frequent disorder with high impact on morbidity and mortality and significant burden on healthcare-related cost. In France, the 2018-2019 flu epidemic has led to 13,100 all-cause death including 9,900 death directly related to the viral infection. As cross-transmission of influenza is responsible for nosocomial outbreaks, preventing transmission of infectious agents in healthcare settings is a major issue. If vaccination of patients and healthcare givers remains cornerstone, control procedures are mandatory. Therefore patients admitted with influenza require isolation precautions including admission in a single room and protective measures. Based on experts advise, isolation is currently recommended for 5 to 8 days. Duration of isolation depends on immune status and antiviral therapy. However, during periods of epidemic, every hospital room is valuable and each ressource has to be tightly used. Risk of contamination is related to the presence of influenza in the upper airways. To the Promoteur 's knowledge, presence of influenza in the upper airways has not been studied in patients receiving oseltamivir. The question is : Do duration of isolation in patients admitted with flu decreas when they are treated with antiviral therapy. To answer this question The Promoteur would aim to determine influenza carriage in the upper airways in in-patients treated by olsetamivir.
