There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this national observational study is to evaluate the Thoraflex™ Hybrid vascular prosthesis in the replacement of the aortic arch and the treatment of aneurysm/dissection of the descending thoracic aorta in relation to morbidity-mortality, visceral malperfusions, neurological and renal complications, endoleak and evolution of the aortic thoracic stent over time.
This study will evaluate the pharmacokinetics, safety, and efficacy of atezolizumab subcutaneous (SC) compared with atezolizumab intravenous (IV) in participants with locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) who have not been exposed to cancer immunotherapy (CIT) and for whom prior platinum-based therapy has failed. The study is comprised of two parts, as follows: A dose-finding part (Part 1, Phase Ib) will aim to identify the dose of atezolizumab SC to be tested in Part 2. A dose-confirmation part (Part 2, Phase III, randomized) will aim to confirm that the dose moved forward from Part 1 yields drug exposure that is comparable to that of atezolizumab IV.
Ibrutinib, a first-in-class Bruton Tyrosine kinase (BTK) inhibitor, has become an established treatment in relapsed/refractory chronic lymphocytic leukemia (CLL). However, despite a considerable improvement of Progression Free Survival (PFS) and Overall Survival (OS) in comparison with historical controls, the prognosis of patients with 17p deletion (del17p) remains a concern, as it is clearly much less favourable than that of patient without del17p. Again, TP53 mutations correlated to poorer prognostic in Relapsed/Refractory (R/R) CLL patients treated with ibrutinib (Brown JR et al,2018). Despite these therapeutic advances, the treatment of CLL with TP53 disruption thus remains a difficult issue that warrants evaluation of alternative treatment strategies, in particular the use of ibrutinib in combination with other agents. A body of evidence suggests that targeting the extracellular molecule CD38 might be an interesting option. CD38 is a transmembrane glycoprotein with multiple receptor and enzymatic functions. The interaction of CD38 with its ligand CD31 (also known as Platelet Endothelial Cell Adhesion Molecule (PECAM-1)) not only plays a role in the binding and the migration of leucocytes through the endothelial cells wall but also triggers the activation of intracellular pathways involved in the differentiation and activation of B cells. Previous results strongly suggest that CD38 favours the expansion of CLL clones not only directly by transducing a proliferation signal but also by directing them to anatomic sites where they find favourable conditions for proliferation and survival. Daratumumab is a first-in-class human IgG1ĸ monoclonal antibody (mAb) that binds CD38-expressing malignant cells with high affinity. Daratumumab induces tumor cell death through multiple mechanisms such as antibody-dependent cell-mediated cytotoxicity (ADCC), complement dependent cytotoxicity (CDC), antibody-dependent cellular phagocytosis (ADCP) and induction of apoptosis (de Weers et al, 2011). Recent data show that daratumumab may also display an immunomodulatory effect through depletion of a subset of immunosuppressive CD38+ Tregs (Krejcik et al, 2016). Early-stage clinical trials found daratumumab to be safe and to display encouraging clinical activity as a single agent in relapsed/refractory multiple myeloma (MM) patients (Lockhorst et al 2016, Lonial et al, 2016). Overall response rate was 31%, with rapid (median 1 month) and durable responses in this heavily pretreated MM population. Interestingly, no patient discontinued the treatment because of drug-related adverse events. These results led to approval of daratumumab in relapsed/refractory MM in December 2015. The clinical efficacy of daratumumab along with its very favourable safety profile supports its investigation in other lymphoproliferative malignancies. In particular, the expression of CD38 in poor prognosis CLL and the key role of CD38 in CLL biology provide a basis for examining the potential of daratumumab in this disease. In preclinical studies, (Matas-Céspedes et al, 2016; Manna et al, 2017) Daratumumab efficiently kills CLL cell lines and patient-derived CLL cells by ADCC and ADCP in vitro. Daratumumab modulates CLL-T reg levels and increase cytotoxic effector T cells. Rationale for combining ibrutinib with daratumumab: These data suggest that combining ibrutinib with daratumumab might have a synergistic or additive effect. Both drugs inhibit B cell receptor (BCR) signalling via two different converging pathways, i.e. BTK and CD38/ZAP70/ERK (Deaglio et al, 2007). In vitro, Manna et al have shown that daratumumab is able to modulate BCR signaling. Interestingly, the ibrutinib /daratumumab combination significantly enhanced mitochondrial-mediated apoptosis bth in CD38 high and CD38 low CLL cells (Manna et al, 2017). Altogether, this provides a rationale for evaluating the safety and efficacy of the association of daratumumab with ibrutinib in high-risk relapsed/refractory patients for whom the standard-of-care using ibrutinib as a single agent has demonstrated limitations in terms of long-term disease control. Primary objective of the study: to determine the efficacy of a treatment combining daratumumab and ibrutinib in a poor risk population of relapsed CLL patients with TP53 dysfunction. Secondary objectives of the study : to determine the safety profile of daratumumab in combination with ibrutinib in CLL patients. Inclusion period: 24 months Treatment duration (ibrutinib + daratumumab): continuous, until disease progression or unacceptable toxicity. Follow-up period: will begin once the subject discontinues study treatment, during 2 years.

The purpose of this study is to evaluate the efficacy and safety (including evaluating side effects) of combination of olaparib and abiraterone versus placebo and abiraterone in patients with metastatic castration-resistant prostate cancer (mCRPC) who have received no prior cytotoxic chemotherapy or new hormonal agents (NHAs) at metastatic castration-resistant prostate cancer (mCRPC) stage.
A Global Study to Determine the Efficacy and Safety of Durvalumab in Combination with Gemcitabine+Cisplatin for Neoadjuvant Treatment and Durvalumab Alone for Adjuvant Treatment in Patients with Muscle-Invasive Bladder Cancer
Over the past decade, advances in diagnosis and treatments have dramatically increased the rates of cure for young patients with cancer. As a consequence, a new population of cancer survivors has emerged whose fertility is compromised after cancer therapy. Indeed, gonadotoxicity is a well-known long-term side effect of cancer treatment in young patients having survived malignant diseases. More than 80% of women of childbearing age, treated for breast cancer with standard protocol of neoadjuvant (4 cycles of 5-fluorouracile - epirubicin- cyclophosphamide (FEC) and 4 cycles of docetaxel) or adjuvant chemotherapy (3 FEC and 3 docetaxel), show an alteration of their ovarian reserve 2 years after completion of the treatment, as a result of chemotherapy-related follicular loss. Therefore, according to the extent of the follicular damages, the gonadal function may vary from moderate to severe diminished ovarian reserve (DOR) and possibly to the ultimate stage of premature ovarian insufficiency (POI). Investigators propose a multicentric and prospective study of a cohort of young women with breast cancer to evaluate whether genetic polymorphisms, previously identified as being correlated with age at menopause in the healthy population, are associated with the intensity of the follicular decline following chemotherapy in young breast cancer survivors.
This is a Phase 2, randomized, double-blind, placebo-controlled study comparing the efficacy and safety of avapritinib + best supportive care (BSC) with placebo + BSC in patients with indolent systemic mastocytosis (ISM) whose symptoms are not adequately controlled by BSC. The study will be conducted in 3 parts. All patients will receive treatment with avapritinib during Part 3 including those rolling over from the placebo group.
Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. QFR is estimated based on two angiographic projections. Studies have shown a good correlation with the present wire-based standard approach Fractional Flow Reserve (FFR) for assessment of intermediate coronary stenosis. The purpose of the FAVOR III Europe Japan study is to investigate if a QFR-based diagnostic strategy will results in non-inferior clinical outcome after 12 months compared to a standard pressure-wire guided strategy in evaluation of patients with chest pain (stable angina pectoris) and intermediate coronary stenosis.
This aim of the study is to set up a procedure for screening for undernutrition in the neurovascular intensive care unit. This screening procedure follows a specific work concerning undernutrition in thrombolyzed patients (NCT03303820). This work was motivated by the fact that, despite a high frequency of undernutrition in the hospital (at least 30% of patients), undernutrition in neurovascular unit is studied very little. A cohort of thrombolysed patients in 2014 was studied retrospectively. Patients malnourished at the entrance had a non-significant, less good recovery of their stroke (+ 1 Rankin score point at 3 months in malnourished patients at the entrance).
