Vaccine market access pathways in the EU27 and the United Kingdom-analysis and recommendations for improvements

Background: Vaccine market access (VMA) pathways across the European Union (EU) and the United Kingdom (UK) are complex, lengthy, and heterogeneous, particularly when compared with pharmaceuticals. The knowledge base to inform recommendations for optimization of VMA is lacking. We therefore conducted a comprehensive evaluation of EU VMA pathways. Methods: Research in two phases included: (1) mapping VMA pathways in each EU member state (including the UK) based on a literature review, expert interviews, and mathematical archetyping; and (2) interviews with vaccine experts to identify barriers, drivers, and recommendations for regional VMA alignments. Results: Key steps in VMA across the EU include horizon scanning, early advice, National Immunization Technical Advisory Group (NITAG) recommendation for inclusion in national immunization programs, health technology assessment (HTA), final decision and procurement. We found significant complexity and heterogeneity, particularly for early advice, and in the roles, decision-making criteria, and transparency of NITAGs and HTA bodies. The most important drivers for rapid VMA included demonstration of disease burden and vaccine benefit (e.g., efficacy, safety, economic). Key barriers were budget limitations and complexity/clarity of VMA processes (e.g., need for national-regional consensus, clarity on process initiation, and clarity on the role of HTA). Recommendations for alignment at EU and member-state levels include information sharing, joint clinical assessment, initiatives to address funding and political barriers, and improved transparency by decision-making bodies. Early engagement with vaccine stakeholders was a key recommendation for manufacturers. Conclusions: There is significant potential for alignment, collaboration, and improvement of VMA across the EU. Roles, responsibilities, and transparency of key bodies can be clarified. The COVID-19 pandemic response should stimulate policies to improve access to all vaccines, including routine ones, and form the foundation upon which a consistent vaccine ecosystem can be created for the EU, one that is resilient, consistent between member states, and fit for purpose

A new molecular classification to drive precision treatment strategies in primary Sjögren’s syndrome

There is currently no approved treatment for primary Sjögren's syndrome, a disease that primarily affects adult women. The difficulty in developing effective therapies is -in part- because of the heterogeneity in the clinical manifestation and pathophysiology of the disease. Finding common molecular signatures among patient subgroups could improve our understanding of disease etiology, and facilitate the development of targeted therapeutics. Here, we report, in a cross-sectional cohort, a molecular classification scheme for Sjögren's syndrome patients based on the multi-omic profiling of whole blood samples from a European cohort of over 300 patients, and a similar number of age and gender-matched healthy volunteers. Using transcriptomic, genomic, epigenetic, cytokine expression and flow cytometry data, combined with clinical parameters, we identify four groups of patients with distinct patterns of immune dysregulation. The biomarkers we identify can be used by machine learning classifiers to sort future patients into subgroups, allowing the re-evaluation of response to treatments in clinical trials

Effectiveness of Montelukast on asthma control in infants: methodology of a French claims data study

International audienceBackground: This pilot study, conducted on a 1/97th representative sample of French claims data, prepared a project to assess the effectiveness of Montelukast (MTL-4) as add-on therapy for asthma in infants (6–24 months) compared to inhaled corticosteroids (ICS), based on real-world data. Due to the very recent opening of French claims data for effectiveness research, and the complex structure of this data source, we first tested the feasibility of identifying infants with asthma and outcome criteria, and the ability to perform relevant comparisons. Methods: We identified a cohort of infants with uncontrolled asthma and receiving ≥2 consecutive dispensations of any respiratory drug (R03 ATC classification) during a 6-month period. Uncontrolled asthma was identified either from exacerbations or from markers of acute loss of asthma control; date of occurrence of an event (exacerbation and/or acute loss of asthma control) was defined as index date. The study groups comprised infants receiving MTL-4 +/− ICS (MTL-4 group) or ICS without MTL-4 (ICS group) at index date. These two groups were matched on gender, age, quarter of index date, therapy before index date, past asthma-related hospitalization (ever), and were followed for 6 months. The outcome was the rate of infants with uncontrolled asthma, defined as above

Recurrent Wheezing in Infants: A Population-Based Study

International audienceRecurrent wheezing (RW) has a significant impact on infants, caregivers, and society, but morbidity and related medical resource utilization (MRU) have not been thoroughly explored. The burden of RW needs to be documented with population-based data. The objective was to assess the characteristics, medical management, and MRU of RW infants identified from national claims data.Infants aged from 6 to 24 months, receiving >=2 dispensations of respiratory drugs within 3 months, and presenting a marker of poor control (index date), were selected. During the 6 months after index date, MRU was described in the cohort and among 3 subgroups with more severe RW, defined as >=4 dispensations of respiratory drugs, >=3 dispensations of oral corticosteroids (OCS), or >=1 hospitalization for respiratory symptoms.A total of 115,489 infants had RW, corresponding to 8.2% of subjects in this age group. During follow-up, 68.7% of infants received inhaled corticosteroids, but only 1.8 U (unit) were dispensed over 6 months, suggesting discontinuous use. Control was mostly inadequate: 61.7% of subjects received OCS, 80.2% antibiotics, and 71.2% short-acting beta-agonists, and medical/paramedical visits were numerous, particularly for physiotherapy. Severe RW concerned 39.0% of the cohort; 32.8% and 11.7% of infants had repeated use of respiratory drugs and OCS, respectively, and 5.5% were hospitalized for respiratory symptoms.In this real-life nation-wide study, RW was common and infants had poor control and high MRU. Interventions are needed to support adequate use of controller therapy, and to improve medical care

La neuro-oncologie des adolescents et adultes jeunes (AJAS) : place d’une RCP nationale. Au nom de l’ANOCEF, GO-AJA et de la SFCE

International audienceThe skills of adult versus pediatric neuro-oncologists are not completely similar though additive. Because the tumors and their protocols are different and the tolerance and expected sequelae are specific. Multidisciplinary meetings including adult and pediatric neuro-oncologists are warranted to share expertise. Since 2008, a weekly national web based conference was held in France. Any patient with the following criteria could be discussed: Adolescent and Young Adults aged between 15 and 25 years, and any adult with a pediatric type pathology, including medulloblastoma, germ cell tumors, embryonic tumors, ependymoma, pilocytic astrocytoma.ResultsAttendance during the year 2015 was as follows: 42 meetings were held; the median number of cases discussed at each meeting was 4 (1 to 8); the mean number of attendants was 7 (2 to 12). One hundred and sixty-eight cases concerning 121 patients were discussed. Mean age was 30 years old (7 to 67). Forty-eight percent were discussed at diagnosis. The patients had mostly medulloblastomas (40%), germ cell tumors (11%), ependymomas (11%), pineal tumors (7%) and embryonal tumors (8%). The rate of inclusion in protocols was increased since the opening of this web conference, especially for the germ cell tumor SIOP protocol that is opened without age restriction, and in RSMA standard risk or MEVITEM relapse adult medulloblastoma protocols.ConclusionMultidisciplinary Web conference for AYAs is feasible and increases the inclusion rate in protocols. It should be developed further.Les compétences en neuro-oncologie pédiatrique et adulte sont différentes mais complémentaires car les histologies, les protocoles thérapeutiques, la tolérance à court et moyen termes et les séquelles tardives attendues sont spécifiques à chaque tranche d’âge. Depuis 2008, ont été mises en place des réunions virtuelles nationales de concertation pluridisciplinaires hebdomadaires initialement dédiées aux adolescents et jeunes adultes (AJA) (15–25 ans) suspects ou porteurs d’une tumeur du système nerveux central dont l’incidence et l’expertise sont plus importantes en milieu pédiatrique. L’expertise a par la suite aussi bénéficié aux adultes plus âgés porteurs de ces affections. En 2015, 168 cas concernant 121 patients ont été discutés lors de 46 réunions. Le nombre moyen de dossiers discutés était de 4 (1 à 8). L’âge moyen de patients présentés était de 30 ans (7 à 67). Dans 48 % des cas, la discussion portait sur la prise en charge initiale. Le nombre moyen de thérapeutes présents était de 7 (2 à 12). Les histologies concernaient principalement des médulloblastomes 40 %, tumeurs germinales malignes 11 %, épendymomes 11 %, tumeurs pinétumeurs embryonnaires 8 %. La RCP AJA a donc prouvé la faisabilité et l’intérêt d’un échange centré sur cette sous-population, entre spécialistes de la neuro-oncologie d’origine diverses. Elle a permis d’optimiser la prise en charge de ces maladies orphelines, et l’inclusion dans des protocoles nationaux et internationaux, en particulier pour les tumeurs germinales malignes intracrâniennes ouverts à tous âges, et les protocoles s’adressant aux médulloblastomes en première ligne (RSMA) ou en rechute (MEVITEM)
