NCT ID: NCT03774732 Recruiting - Clinical trials for Non Small Cell Lung Cancer

PD-1 Inhibitor and Chemotherapy With Concurrent Irradiation at Varied Tumour Sites in Advanced Non-small Cell Lung Cancer

NIRVANA-LUNG
Start date: March 21, 2019
Phase: Phase 3
Study type: Interventional

Overall survival (OS) of patients with advanced (stage IIIB/IV) non-small-cell lung cancer (NSCLC) remains short after the first line of treatment with a median OS of 12.2 months in non squamous NSCLC and 9.2 months in squamous NSCLC . In this setting the programmed death 1/ligand 1 (PD-1/-L1) were targeted with nivolumab (IgG4) in advanced squamous and nonsquamous NSCLC leading to an increase of the 1-year OS rate of approximately 10-15% in both histologies. Nivolumab, pembrolizumab and atezolizumab are now considered a standard of care in 2nd line advanced NSCLC and in 1st line for pembrolizumab but but prognosis still remains poor in advanced NSCLC. Overall survival (OS) of patients with advanced (stage III/IV) NSCLC remains limited with a median OS of 12.2 months in non-squamous NSCLC and 9.2 months in squamous NSCLC if anti-PD1 alone. It is of around 16 months if pembrolizumab is combined with chemotherapy. Preclinical data indicates that anti-tumor efficacy is increased when anti-PD-1/-L1 are combined with irradiation (IR). Radiotherapy alone can elicit tumor cell death which can increase tumor antigen in the blood stream, favoring recognition by the immune system and its activation against tumor cells outside of the radiation field (="abscopal effect"). IR may also reverse acquired resistance to PD-1 blockade immunotherapy by limiting T-cell exhaustion. Because of these preclinical and clinical data several studies analysing the combination of IR and anti-PD1 in NSCLC are ongoing. Among them, two studies are testing the administration of IR and nivolumab in stage III NSCLC: the NCT02768558 phase III trial (RTOG), and the NCT02434081 phase II trial (ETOP). Antonia et al [2017] tested the use of anti-PD-L1 after chemoradiotherapy in unresectable stage III NSCLC. Median time to distant metastasis was increased (23.2 months vs. 14.6 months, p<0.001). An increase of OS is consequently expected. However, no study involving concurrent RT and pembrolizumab combined with chemotherapy in advanced NSCLC is ongoing, which is the purpose of the present study, NIRVANA-Lung.

NCT ID: NCT03445845 Recruiting - Clinical trials for Axial Spondyloarthritis

Rotation or Change of Biotherapy After TNF Blocker Treatment Failure for Axial Spondyloarthritis

ROC-SPA
Start date: December 14, 2018
Phase: Phase 4
Study type: Interventional

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease characterized by inflammatory arthritis and enthesitis involving the spine. AxSpA prevalence is around 0.17% of the French population. Tumor necrosis factor (TNF) was the first target defined in axSpA. Since one third of axSpA patients failed to the first TNF blocker, many axSpA patients received a second biological Disease-Modifying AntiRheumatic Drugs (bDMARDs). Until few months, the only choice was to use a second TNF blocker.Since 2003, pharmaceutical companies investigated efficacy of TNF blockers already used in rheumatoid arthritis. Etanercept is a fusion protein with TNF receptor type II p75 and IgG1 Fc fragment, whereas adalimumab, infliximab, and golimumab are monoclonal antibodies. Certolizumab is a fusion between a fab fragment targeting TNF and a Peg fraction. All demonstrated efficacy versus placebo in a randomized double blinded study In case of failure to the first TNF blockers, rheumatologists will follow the "Treat-to-Target" principle. This approach already demonstrated its benefit in rheumatoid arthritis or in psoriatic arthritis. This concept was also suggested for axSpA with low levels of evidence and recommendation. So rheumatologist will provide the best treatment in case of failure to the first TNF blockers, which is a daily clinical situation. Since few months, rheumatologists have the choice between targeting IL-23/17 axis compared to a second TNF blocker.

NCT ID: NCT03271762 Recruiting - Clinical trials for Mitral Regurgitation

Multicentre Study of MITRACLIP® Transcatheter Mitral Valve Repair in Patients With Severe Primary Mitral Regurgitation Eligible for High-risk Surgery

MITRA-HR
Start date: March 2, 2018
Phase: N/A
Study type: Interventional

The objective of the study is to demonstrate the non-inferiority for clinical efficacy of an endovascular treatment strategy with the MitraClip® in comparison with a surgical treatment strategy in patients with severe primary mitral regurgitation judged eligible for anatomical repair with the MitraClip® or mitral valve surgery with high surgical risk. This trial is a French and Monegasque, multicenter and randomized trial. Patients enrolled will be clinically followed for 2 years ( clinical visit at 1 month, at 6 months and 12 months, phone call at 18 months and clincial visit at 24 months).

NCT ID: NCT03053141 Recruiting - Cardiac Arrythmias Clinical Trials

RHythmia mAPping and Signal acquisitiOn for Data analYsis (RHAPSODY)

RHAPSODY
Start date: May 2016
Phase:
Study type: Observational

The objective of the RHAPSODY study is to evaluate the performance of new software features in subjects undergoing standard of care catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System. Results from this study will be used to guide development and refinement of new software features that may be implemented in future commercial software releases.

NCT ID: NCT01210274 Recruiting - Clinical trials for Myelodysplastic Syndromes or Acute Myeloid Leukemia With Multilineage Dysplasia

Characterization of the Mechanisms of Resistance to Azacitidine

Start date: September 2010
Phase: N/A
Study type: Observational

Myelodysplastic syndromes (MDS) are frequent diseases in elderly patients (median age: 71 years). IPSS classification defines low risk (Low and Intermediate 1), and high risk (Intermediate 2 and High) MDS. High-risk MDS (MDS-HR) have a high risk of transformation into acute leukemia with multilineage dysplasia (AML-DML). The success of Azacitidine has been mainly achieved through a rigorous empirical and clinical research, but the molecular mechanisms by which this molecule exerts its effects remain poorly characterized. The primary mode of action of Azacytidine is through DNA demethylation, and integration in to mRNA that favor traduction inhibition. The impact of this molecule on various cell death programs involved in the elimination of leukemic cells : apoptosis and autophagy is currently poorly known. The research program and clinical studies we proposed focus on two major aspects: - Main objective: Molecular mechanism of action and resistance to Azacitidine: Role of apoptosis versus autophagy. - Secondary Objective: Reversion of Azacytidine resistance using different drugs targeting apoptosis and/or autophagy. Our laboratory has identified new molecules to selectively induce different types of cell death (apoptosis or autophagy).
