1.0 Hypothesis for the study Antibiotic therapies currently recommended for the treatment of acute pyelonephritis (AP) in children, whether fully by the oral route or initially intravenous (IV, 3 days) followed by the oral route, have a duration of 7 to 14 days (10 days in France). In children with no prior urological malformation, the global clinical and microbiological cure rate after antibiotic treatment completion is around 95%. Recurrence occurs in less than 5% of cases in the 3 months following AP. Renal scarring, when documented, concerns 15% of children 6 months after treatment. Renal scarring can be associated with chronic renal disease. The investigators hypothesize that 3 days of IV treatment is equivalent to extending to 10 days with an oral therapy to prevent long-term renal scarring. The investigators also hypothesize that while achieving equivalent clinical and microbiological success, and prevention of re-infections in the following 3 months, 3 days of IV treatment reduces the risk of acquisition of resistant strains of Enterobacteriaceae and increases the gut microbotia diversity compared to extending to 10 days with an oral therapy. 2.0 Description of knowledge relating to the condition in question Acute pyelonephritis (AP) is the most common proven bacterial infection in pediatric clinical practice. It can lead to sepsis or renal abscess and induce long-term complications such as renal scarring. Renal scarring during childhood can lead to hypertension or chronic renal disease at adult age, although the link between AP and chronic renal disease has not been firmly established. AP is most frequently due to Enterobacteriaceae, mainly Escherichia coli. Extended-spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) now account for 5% of AP in France and represent a serious threat to public health, owing to limited therapeutic options. The overall clinical success rate in children treated for AP is around 95% and is not significantly different when ESBL-E are implicated. In children with no prior urological malformation, recurrence in the following 3 months occurs in less than 5% of cases. Antibiotic treatment decreases the risk of renal scarring, which remains important, around 15% (95% CI: 11-18) in the largest meta-analysis. Moreover, delay in treatment of AP is associated with permanent renal scarring. In children without prior urological malformation, acute complications are exceptional, even in the presence of bacteraemia. Short courses of intravenous (IV) antibiotics (2-4 days) followed by oral therapy have proved to be as efficient as longer courses (7-14 days) of IV treatment. For children aged ≥ 1 month, oral treatment alone for 10 to 14 days has proved non inferior to initial IV antibiotics (2-4 days) followed by oral therapy (total 10 to 14 days). French Paediatric guidelines recommend a short course (up to 4 days) of IV amikacin and/or ceftriaxone followed by oral therapy (total 10 days), with the possibility, for children aged \> 3 months of a 10-day course of oral cefixime \[12\]. In children initially treated IV, the oral relay occurs once the urine culture and antibiogram are available. The American Association of Pediatrics that focused on children aged 2 to 24 months recommends either an oral or a sequential IV/oral treatment for a total of 7 to 14 days, while the British NICE guidelines recommend an exclusively oral route only for children aged ≥ 3 months In practice, most centers initiate an IV treatment in a large subset of patients (ongoing practice analysis on the management of AP in children in France, personal data, to be published in 2021). An initial IV treatment is particularly used in young children, with an age cut-off varying between 3 months and 3 years according to the center. It is also used to secure the absorption of the treatment if the child vomits, is unable to take oral antibiotics or is severely unwell. The excellent short-term and the good long-term clinical outcomes in children treated for AP questions the need for a 10-day course of antibiotics. In adults, shorter treatments, such as amikacin for 5 days, have been validated for the treatment of uncomplicated AP. Recently published studies (Zaoutis 2023, Montini 2024) have compared a 5-day oral treatment vs 10-day oral treatment for AP in children. However, the first study (Zaoutis 2023) mainly included (63%) children with a non-febrile urinary tract infection (ie not an AP). The second only included children aged \> 3 month. A practice survey conducted prior to our protocol had shown that many departments were already reluctant to treat infants under 1 year old, and particularly those under 3 months old, by oral route, warranting clinical trials including children \< 3 month old. Third-generation cephalosporins (3GC), such as ceftriaxone, rapidly reduce the richness and diversity of the gut microbiota and also select subpopulations of resistant bacteria, particularly by acquisition of extended spectrum beta-lactamases, a major public health issue. There is no data on the impact of antibiotic relays on the gut microbiota. Since each antibiotic has its own anti-bacterial spectrum, a sequence of treatments could have an additive or even synergistic deleterious effect on the gut microbiota. This may in particular be the case in children treated with IV ceftriaxone for 3 days followed by cotrimoxazole for 7 days, as recommended in France in first intention. 3.0 Summary of relevant pre-clinical experiments and clinical trials 1999 Hoberman et al. Oral versus initial intravenous therapy for urinary tract infections in young febrile children This was a non-inferiority study between oral cefixime for 14 days and intravenous ceftriaxone for 3 days followed by oral cefixime for 11 days. One of the outcomes was the occurrence of renal scarring. It included children aged 1 to 24 months. A total of 306 children were included. Renal scarring at 6 months was noted in 9.8% children treated orally versus 7.2% of children treated intravenously. The study conclude that oral treatment was safe. The main limit of the study was the lower rate of renal scar in both arms compared to other studies, probably linked to a female/male sex ratio of 9:1 (with a median age of 8 months), when the sex ratio is in favour of boys before 1-year-old. 2007, Montini et al. Antibiotic treatment for pyelonephritis in children: multicentre randomised controlled non-inferiority trial This was a multicentre, randomised controlled, open labelled, parallel group, non-inferiority trial comparing oral co-amoxiclav for 10 days to parenteral ceftriaxone for three days, followed by oral co-amoxiclav for 7 days. Primary outcome was the rate of renal scarring after 12 months. A total of 502 children aged 1 month to \<7 years with clinical pyelonephritis were included. Intention to treat analysis showed no significant differences between oral (n=244) and parenteral (n=258) treatment, both in the primary outcome (scarring scintigraphy at 12 months 27/197 (13.7%) v 36/203 (17.7%), and secondary outcomes: time to defervescence, white cell count at day 3, and percentage with sterile urine at day 3 (99.5% n both arms). The results were similar in the subgroups of children older and younger than 2 years (data not shown in the paper). 2012, Boquet et al. Randomized trial of oral versus sequential IV/oral antibiotic for acute pyelonephritis in children PHRC AOM 04 105; NCT00136656 This was a non-inferiority study between oral cefixime for 10 days and IV ceftriaxone for 4 days followed by oral cefixime for 6 days on the occurrence of renal scarring. It included children aged 1 to 36 mont with a first proven urinary tract infection and procalcitonin concentration ≥ 0.5 ng/mL s. The primary endpoint was the proportion of renal scar measured by 99mTc-DMSA renal scintigraphy 6 to 8 months after treatment. The study included a total 171 children of the 698 expected. The incidence of renal scarring was 30.8% in the oral treatment group and 27.3% for children who received the sequential treatment. The trial could not demonstrate statistically the non-inferiority due to insufficient enrolment. 2023, Zaoutis et al. Short-Course Therapy for Urinary Tract Infections in Children: The SCOUT Randomized Clinical Trial PMID: 37358858 ; NCT01595529, This was a randomized clinical noninferiority trial at 2 children's hospitals. Participants included children aged 2 months to 10 years with UTI exhibiting clinical improvement after 5 days of antimicrobials. The study compared another 5 days of antimicrobials (standard-course therapy) or 5 days of placebo (short-course therapy). The primary outcome, treatment failure, was defined as symptomatic UTI at or before the first follow-up visit (day 11 to 14 A total of 664 children were randomized (639 female \[96%\]; median age, 4 years): 2 of 328 assigned to standard-course (0.6%) and 14 of 336 assigned to short-course (4.2%) had a treatment failure. There were no differences between groups in rates of UTI after the first follow-up visit, incidence of adverse events, or incidence of gastrointestinal colonization with resistant organisms. 2024, Montini et al. Short Oral Antibiotic Therapy for Pediatric febrile Urinary Tract Infections: A Randomized Trial. \[25\] PMID: 38146260 This was a multicenter, investigator-initiated, parallel-group, randomized, controlled trial. We randomly assigned children aged 3 months to 5 years with a noncomplicated fUTI to receive amoxicillin-clavulanate for 5 or 10 days. The primary end point was the recurrence of a urinary tract infection within 30 days after the completion of therapy. Secondary end points were the difference in prevalence of clinical recovery, adverse drug-related events, and resistance to amoxicillin-clavulanic acid and/or to other antibiotics when a recurrent infection occurred. The study included a total of,175 children and 142 underwent randomization. The recurrence rate of UTI within 30 days of the end of therapy was 2.8% (2/72) in the short group and 14.3% (10/70) in the standard group. The recurrence rate of fUTI within 30 days from the end of therapy was 1.4% (1/72) in the short group and 5.7% (4/70) in the standard group.

Despite substantial progress made in the first- and second line mCRC settings, there are still unmet clinical needs for patients harboring BRAFV600E mutations, especially those with microsatellite stability (MSS) / proficient mismatch repair (pMMR) tumor. The overall survival and access to different treatment in the real-life setting are unknown. Moreover, patient prognosis remains poor and therapeutic resistance to combinations with BRAF inhibitors, is at present, nearly universal. Therefore, it seems essential to prospectively collect clinical and biological data about this rare mCRC subtype. These data will allow us to improve knowledge and to identify clinical and biological factors that could drive therapeutic decisions, predict resistance to treatments, and that are prognostic for survival. In this context, we designed this large, prospective, cohort study to collect clinical data and biological samples to be used for research but also to gather real-world clinical data concerning the treatments and the survival outcomes in patients with BRAFV600E mCRC. This collection of clinical and biological data (tumor tissue and blood samples) will allow us to identify predictive and prognostic biomarkers with several research work packages planned: i. To evaluate the circulating tumor DNA (ctDNA) during the metastatic first-, second-, and third-line treatment to: * Evaluate its positive and negative predictive value. * Identify molecular alterations preceding and explaining clinical resistance during BRAF/EGFR inhibition therapy and immunotherapy. ii. To evaluate BRAFV600E mCRC immune environment both at the tumor and blood level (immunomonitoring). iii. To study specific the dMMR/MSI BRAFV600E subgroup. Furthermore, the data collected will describe the therapeutic management of BRAFV600E mCRC patients in the routine-practice setting which will bring very useful data. The results of the COBRAF study could lay the groundwork to better understand BRAFV600E mCRC and to identify prognostic and predictive biomarkers helping the development of new therapeutic approaches in this population.

BACKGROUND Non-muscle infiltrating bladder tumors are a cancerous pathology with an estimated incidence of 13,000 new cases/year in France. ¾ of new cases are diagnosed at a stage where the cancer is of limited extension to the urothelial mucosa and/or its underlying chorion (non-muscle-invasive bladder cancer NMIBC). The management and follow-up of NMIBCs are performed according to the best practice recommendations issued by the Cancer Committee of the French Urology Association. The risk of recurrence at 1 and 5 years for NMIBC has been estimated in clinical trials to be between 15%-61% and 31%-78%, respectively, depending on grade, stage, number, size, frequency of previous recurrence and presence of carcinoma in situ. In this context, patients should have regular endoscopic examinations to ensure the absence of tumor lesions inside their bladder. Urine cytology pathology is recommended for the detection of recurrence of NMIBC. However, the negative predictive value of this examination does not allow it to be substituted for bladder endoscopy, as the risk of not recognizing a bladder tumor, especially of low grade, is too high. To date, no urinary biomarker has been shown to be clinically useful and their use is not recommended for the non-invasive detection of endovesical tumor recurrence. Urine sampling is recommended prior to bladder endoscopy for follow-up of NMIBC to ensure urine sterility (CBEU) and to perform urine cytology in patients with high-grade NMIBC and/or carcinoma in situ. The observational study of the clinical validity of the negative and positive predictive values of the biomarkers in a population of patients followed for a bladder tumor previously characterized is able to demonstrate the possibility of postponing the realization of the cystoscopy according to the tumoral characteristics and the treatments received by the patients. OBJECTIVES The main objective of the research will be to evaluate the diagnostic performance of biomarkers available in France, performed on a urine sample and providing a binary result (positive: probable presence of a tumor recurrence; negative: probable absence of a tumor recurrence) to the result of the bladder endoscopy performed as part of the routine care for the follow-up of NMIBC: determination of the negative and positive predictive values of biomarkers. The secondary objectives will be to describe the anatomopathological characteristics, the pathological history and the treatments received in the population, as well as analyze demographic and regional disparities in the treatment profiles of these diseases. MATERIAL AND METHOD When the patient is included in the study, medical data relating to the patient's pathology, including all previous treatments, will be entered into the register, as well as the name and result of the biomarker carried out before the resection (biopsy). At each follow-up endoscopic examination scheduled in the patient's personalized care plan, the investigating urologist will record its date and endoscopic findings (white light bladder fibroscopy). The name and result of the urine test will also be recorded by the urologist. The performance of the test will be evaluated from these data by calculating sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) and by means of an analysis of variance (ANOVA) to explore possible differences within the test by tumor grade and stage, and according to previous endovesical treatments received. The inclusion target is 8000 patients in France over a 3-year period.

BioEXALK is a prospective study evaluating the biological characteristics of advanced ALK-rearranged NSCLC treated with new generation TKIs in first line, included in the national EXPLORE ALK cohort (GFPC 03-2019). Explore ALK GFPC 03-2019 is a non-interventional, national, multi-center cohort of ALK-rearranged NSCLC patients, whose RCB reference is 2020-A00771-38 and which obtained an approval from the IDF II Ethic Committee on 25/05/2020. Biological analysis will be performed on tissue at diagnosis and at the time of disease progression when available and on circulating tumor DNA (ctDNA) on three timepoints (diagnosis, at first tumor evaluation and at the time of disease progression). * Tissue : RNAseq will be performed on tumor biopsy (10 slides of 5 microns) to identify the ALK fusion partner and its variant and associated co-mutations.. * ctDNA : NGS panel on DNA including a large panel of fusions and mutations will be performed on blood samples (30mL on EDTA or STRECKs tubes) at diagnosis, at the time of the first evaluation and at the time of progression). For plasma testing, after obtained patient consent, blood samples (35mL on EDTA or STRECKs tubes) at diagnosis, at the first evaluation and at disease progression will be taken. The ALKis include alectinib and brigatinib as first-line therapy or other drugs with marketing authorizations (lorlatinib, entrectinib) or in early access programs (EAPs). Liquid biopsies will be analyzed with a NGS panel allowing the identification of ALK fusion partners and resistance mechanisms (mutations, fusions, copy number variations). Samples will be sent for centralized analysis to the Léon Bérard Center (Lyon). For biological analysis on tissue obtained at diagnosis, the ALK fusion partner and its variant will be identified by RNAseq. Whenever a tissue re-biopsy is performed at the time of disease progression as part of the standard of care management of the patient, the remaining tissue sample will be collected as part of the BioExALK study, so that RNAseq analysis will be performed to look for resistance mechanisms. Tissue samples (10 slides of 5 microns) will be sent for centralized analysis to the Rouen University Hospital.

This is a phase II-III randomized, open-labelled, multicentre study for NSCLC patients who are naive of treatment for advanced disease. Patients will be given first-line chemotherapy + pembrolizumab: platinum doublet for at least 3 cycles, either paclitaxel-carboplatin for patient with SCC or 3 cycles of pemetrexed-platinum salt followed by 2 cycles of pemetrexed and 6 cycles of pembrolizumab. Only patients with disease control, confirmed at 6 months (27-weeks) without drug-related toxicity imposing treatment discontinuation will be randomized 1:1 either to continuation of pembrolizumab (± pemetrexed for non-SCC) until disease progression or unacceptable toxicity or 2 years, or observation (± pemetrexed for non-SCC). Patients will be stratified by performance status (0 versus 1), histology (SCC versus non-SCC), PD-L1 (PD-L1 \< 1% versus 49%≥PD-L1 ≥ 1% versus PD-L1\>49%), sex and response at randomization (partial response versus stabilisation).

This study is open to adults with type 2 diabetes, high blood pressure, and cardiovascular disease. People can join the study if they have these conditions and do not have a history of heart failure. The purpose of this study is to find out if a medicine called vicadrostat, when taken with empagliflozin, helps reduce cardiovascular risk in people with these conditions. The study will compare this combination to a placebo version of vicadrostat with empagliflozin. Participants are put into 2 groups randomly, which means by chance. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets with empagliflozin. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take a tablet once per day for 2 and a half years and up to 4 years and 3 months. All participants also continue their medication for type 2 diabetes, high blood pressure, and cardiovascular disease. Participants have an equal chance of receiving the study medicine or placebo. Participants are in the study for up to 4 years and 3 months. During this time, they visit the study site regularly. During these visits, doctors collect information about participants' health and take blood samples. The doctors document when participants experience cardiovascular events. The doctors also regularly check participants' health and take note of any unwanted effects.

This study is designed as a multicenter, randomized, parallel groups, open-label, phase 3 study in subjects with untreated newly diagnoses Multiple Myeloma eligible for ASCT. 824 patients will be enrolled in this study from approximately 70 study sites. The 2 parts in the Treatment Phase are described below. Part 1: Induction/ASCT/Consolidation Phase (1:1 Randomization) After the screening period, patients will be randomly allocated (1:1) to either: * Arm A (standard of care arm): standard induction therapy with 4 cycles of D-VRd, followed by HDCT (Melphalan) + ASCT, D-VRd consolidation therapy * Arm B (experimental arm): standard induction therapy with 4 cycles of D-VRd, followed by elranatamab and lenalidomide consolidation therapy. Part 2: Maintenance Phase (1:1 Re-randomization) Patients will be re-randomized (1:1) and will enter the Maintenance Phase upon completion of consolidation therapy. * Arm C (standard of care arm): lenalidomide * Arm D (experimental arm): elranatamab

Large-cell neuroendocrine carcinomas (LCNECs) of the lung are lung tumors (2%) included with small-cell lung cancers (SCLCs) in the subgroup of pulmonary neuroendocrine tumors of high-grade malignancy. Histopathological diagnosis of LCNEC is difficult, with a confirmation rate of only 70-80% after centralized expert-pathologist review. The prognosis of advanced LCNECs is poor, with overall survival (OS) of 8-10 months. The platinum-based regimen is the current recommended first-line treatment for advanced LCNECs in analogy with that given for SCLCs. The previous pivotal GFPC 03-02 trial demonstrated the efficacy of first-line platinum-etoposide in advanced LCNECs with a median Progression-Free Survival (PFS), OS and 1-year PFS of 5 months, 7.7 months and 15% respectively. The GFPC 03-2017 trial has recently reported that 75% of the tumor samples of LCNEC express programmed cell death protein-ligand-1 (PD-L1) in immune infiltrating tumor cells (ICs), and PD-L1 expression on ICs has been previously correlated with clinical efficacy of Immune Checkpoint Inhibitors (ICI) in Non-small Cell Lung Cancer. Numerous retrospective studies have also suggested ICI efficacy against LCNECs with significantly prolonged OS observed in ICI-treated LCNEC patients. Recently, the prospective NIPINEC study results demonstrated second-line nivolumab-ipilimumab efficacy against LCNECs. Moreover, at ESMO 2022, the NICE-NEC prospective phase II study on LCNECs of digestive origin found an impressive efficacy of first-line triplet platinum-etoposide-ICI with a median OS of 13,9 months, and 44 % of long survivor patients (OS\>18 months). Finally, the CASPIAN trial demonstrated the superiority of the combination of durvalumab with platinum-etoposide compared to chemotherapy alone in patients with SCLCs, with an acceptable toxicity profile. Therefore, within the network of GFPC centers, the investigators propose a prospective, multicenter, open-label, phase II study with an external control arm (ESME database), that aims at evaluating the efficacy and safety of the combination of durvalumab with platinum-etoposide chemotherapy as first-line treatment in patients with an advanced LCNECs.

The goal of this observational study is to identify and describe the clinical characteristics, health status, socio-economic impacts and quality of life of patients alive for three years after diagnosis of metastatic Lung cancer and no longer receiving cytotoxic chemotherapy. The main question is to identify the needs of these patients in terms of health status (impact of cancer treatments, incidence of new diseases, cardiovascular, diabetes, second cancers), socio-economic aspects, quality of life and return to employment. Participants will be asked to answer quality of life questionnaires at the time of inclusion and 6 and 12 months after inclusion and then, every year up to 5 years in this study. They will be followed regularly, in consultations, according to the usual practices of the physicians in each participating center.
