Uptake of orphan drugs in the WHO essential medicines lists.

Objective: We evaluated the uptake of medicines licensed as orphan drugs by the United States Food and Drug Administration (FDA) or European Medicines Agency (EMA) into the and the from 1977 to 2021.

Methods: We collated and analysed data on drug characteristics, reasons for adding or rejecting medicines, and time between regulatory approval and inclusion in the lists. We compared trends in listing orphan drugs before and after revisions to the inclusion criteria of the essential medicines lists in 2001, as well as differences in trends for listing orphan and non-orphan drugs, respectively.

How to tailor recommendations on the treatment of multi-drug resistant Gram-negative infections at country level integrating antibiotic stewardship principles within the GRADE-ADOLOPMENT framework.

Promoting the optimal use of antibiotics through evidence-based recommendations should be regarded as a crucial step in the global fight against antimicrobial resistance. Within this scope, several guidelines and guidance documents for antibiotic therapy have been published in recent years. All documents underline the limitations of existing evidence and remark on the need for tailoring recommendations at the national level, based on local epidemiology, availability of diagnostics and drugs, and antimicrobial stewardship principles.

Exploratory data on the clinical efficacy of monoclonal antibodies against SARS-CoV-2 Omicron variant of concern.

Background: Recent in-vitro data have shown that the activity of monoclonal antibodies (mAbs) targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) varies according to the variant of concern (VOC). No studies have compared the clinical efficacy of different mAbs against Omicron VOC.

Methods: The MANTICO trial is a non-inferiority randomised controlled trial comparing the clinical efficacy of early treatments with bamlanivimab/etesevimab, casirivimab/imdevimab, and sotrovimab in outpatients aged 50 or older with mild-to-moderate SARS-CoV-2 infection.

[Harmonizing development, approval and access of drugs for rare diseases in Europe.].

In the past few decades, the regulatory system has changed its approach to speed up the assessment and approval of drugs for the treatment of serious and orphan diseases. However, too early assessments may fail to provide solid evidence to define the therapeutic value of drugs and their fair price. As for rare diseases, patients' expectations amplify such criticalities due to the lack of therapeutic alternatives.

Global status of essential medicine selection: a systematic comparison of national essential medicine lists with recommendations by WHO.

Objectives: Examining the availability of essential medicines is a necessary step to monitor country-level progress towards universal health coverage. We compared the 2017 essential medicine lists (EML) of 137 countries to the WHO Model List to assess differences by drug class and country setting.

Methods: We extracted all medicines prioritised at country level from most recently available national EMLs and compared each national EML with the 2017 WHO Model List of Essential Medicines (MLEM) as the reference standard.

Global access to affordable direct oral anticoagulants.

Poor control of cardiovascular disease accounts for a substantial proportion of the disease burden in developing countries, but often essential anticoagulant medicines for preventing strokes and embolisms are not widely available. In 2019, direct oral anticoagulants were added to the World Health Organization's . The aims of this paper are to summarize the benefits of direct oral anticoagulants for patients with cardiovascular disease and to discuss ways of increasing their usage internationally.

Progress towards antibiotic use targets in eight high-income countries.

Objective: To compare antibiotic sales in eight high-income countries using the 2019 World Health Organization (WHO) Access, Watch and Reserve (AWaRe) classification and the target of 60% consumption of Access category antibiotics.

Methods: We analysed data from a commercial database of sales of systemic antibiotics in France, Germany, Italy, Japan, Spain, Switzerland, United Kingdom of Great Britain and Northern Ireland, and United States of America over the years 2013-2018. We classified antibiotics according to the 2019 AWaRe categories: Access, Watch, Reserve and Not Recommended.

Comparison of antibiotics included in national essential medicines lists of 138 countries using the WHO Access, Watch, Reserve (AWaRe) classification: a cross-sectional study.

Background: The WHO Model List of Essential Medicines classified antibiotics into Access, Watch, and Reserve (AWaRe) categories for the treatment of 31 priority bacterial infections as a tool to facilitate antibiotic stewardship and optimal use. We compared the listing of antibiotics on national essential medicines lists (NEMLs) to those in the 2019 WHO Model List and the AWaRe classification database to determine the degree to which NEMLs are in alignment with the AWaRe classification framework recommended by WHO.

Methods: In this cross-sectional study, we obtained up-to-date (data after 2017) NEMLs from our Global Essential Medicines (GEM) database, WHO online resources, and individual countries' websites.

Antibiotic Use Among Hospitalized Children and Neonates in China: Results From Quarterly Point Prevalence Surveys in 2019.

Antimicrobial resistance is a significant clinical problem in pediatric practice in China. Surveillance of antibiotic use is one of the cornerstones to assess the quality of antibiotic use and plan and assess the impact of antibiotic stewardship interventions. We carried out quarterly point prevalence surveys referring to WHO Methodology of Point Prevalence Survey in 16 Chinese general and children's hospitals in 2019 to assess antibiotic use in pediatric inpatients based on the WHO AWaRe metrics and to detect potential problem areas.

Comparison of Demand for Drugs Used for COVID-19 Treatment and Other Drugs During the Early Phase of the COVID-19 Pandemic in Italy.

This cross-sectional study compares demand for drugs for treatment of coronavirus disease 2019 (COVID-19) between the period directly before the COVID-19 outbreak in Italy and the early period of the outbreak.

The Global Landscape of Treatment Standards for Breast Cancer.

Background: Breast cancer (BC) is a leading cause of morbidity, mortality, and disability for women worldwide. There is substantial variation in treatment outcomes, which is function of multiple variables, including access to treatment. Treatment standards can promote quality and improve survival; thus, their development should be a priority for the cancer-control planning.

High global consumption of potentially inappropriate fixed dose combination antibiotics: Analysis of data from 75 countries.

Antibiotic fixed dose combinations (FDCs) can have clinical advantages such as improving effectiveness and adherence to therapy. However, high use of potentially inappropriate FDCs has been reported, with implications for antimicrobial resistance (AMR) and toxicity. We used a pharmaceutical database, IQVIA-Multinational Integrated Data Analysis System (IQVIA-MIDAS®), to estimate sales of antibiotic FDCs from 75 countries in 2015.

Repurposed Antiviral Drugs for Covid-19 - Interim WHO Solidarity Trial Results.

Background: World Health Organization expert groups recommended mortality trials of four repurposed antiviral drugs - remdesivir, hydroxychloroquine, lopinavir, and interferon beta-1a - in patients hospitalized with coronavirus disease 2019 (Covid-19).

Methods: We randomly assigned inpatients with Covid-19 equally between one of the trial drug regimens that was locally available and open control (up to five options, four active and the local standard of care). The intention-to-treat primary analyses examined in-hospital mortality in the four pairwise comparisons of each trial drug and its control (drug available but patient assigned to the same care without that drug).

The "Square Box": Therapeutic Equivalence as a Foundation of the WHO Model List of Essential Medicines.

Every two years, the World Health Organization (WHO) updates its Model List of Essential Medicines, intended as a guide for countries to adopt or adapt in accordance with local priorities and treatment guidelines, for the development of national essential medicines lists. When more than one therapeutic option is available for a given indication, the WHO Model List often includes a single medicine as representative of a group of equivalent and interchangeable medicines. The representative medicine of that group is listed with an accompanying 'square box' symbol.

Promoting Better Clinical Trials and Drug Information as Public Health Interventions for the COVID-19 Emergency in Italy.

According to these authors from the Italian Medicines Agency, “evidence-informed prescribing and clinical trials were beaten off the mark by social media, rumors, and panic in the early phase of the COVID-19 pandemic.” In this article, they describe lessons learned to counteract misleading information and nudge the research community to do high-quality, informative multigroup trials.
