McCubbin ● John W. Ramatowski ● Esther Buregyeya ● Eleanor Hutchinson ● Harparkash Kaur ● 3 2 1 Anthony K. Mbonye ● Ana L. P. Mateus ● Sian E. Clarke Received: 22 December 2020 / Revised: 2 February 2021 / Accepted: 16 February 2021 / Published online: 19 March 2021 © The Author(s) 2021. This article is published with open access Abstract Since the introduction of antibiotics into mainstream health care, resistance to these drugs has become a widespread issue that continues to increase worldwide. Policy decisions to mitigate the development of antimicrobial resistance are hampered by the current lack of surveillance data on antibiotic product availability and use in low-income countries. This study collected data on the antibiotics stocked in human (42) and veterinary (21) drug shops in five sub-counties in Luwero district of Uganda. Focus group discussions with drug shop vendors were also employed to explore antibiotic use practices in the 1234567890();,: 1234567890();,: community. Focus group participants reported that farmers used human-intended antibiotics for their livestock, and community members obtain animal-intended antibiotics for their own personal human use. Specifically, chloramphenicol products licensed for human use were being administered to Ugandan poultry. Human consumption of chloramphenicol residues through local animal products represents a serious public health concern. By limiting the health sector scope of antimicrobial resistance research to either human or animal antibiotic use, results can falsely inform policy and intervention strategies.

  • Antibiotics Currently in Clinical Development
    A data table from Feb 2018 Antibiotics Currently in Global Clinical Development Note: This data visualization was updated in December 2017 with new data. As of September 2017, approximately 48 new antibiotics1 with the potential to treat serious bacterial infections are in clinical development. The success rate for clinical drug development is low; historical data show that, generally, only 1 in 5 infectious disease products that enter human testing (phase 1 clinical trials) will be approved for patients.* Below is a snapshot of the current antibiotic pipeline, based on publicly available information and informed by external experts. It will be updated periodically, as products advance or are known to drop out of development. Because this list is updated periodically, endnote numbers may not be sequential. In September 2017, the antibiotics pipeline was expanded to include products in development globally. Please contact [email protected] with additions or updates.

    Concept Paper: Potential Approach for Ranking of Antimicrobial Drugs According to Their Importance in Human Medicine: A Risk Management Tool for Antimicrobial New Animal Drugs Introduction This concept paper discusses a potential approach to considering the human medical importance of antimicrobial drugs when assessing and managing antimicrobial resistance risks associated with the use of antimicrobial drugs in animals. In 2003, FDA established a list ranking antimicrobial drugs according to their relative importance in human medicine primarily for the purpose of supporting a qualitative risk assessment process outlined in agency guidance. It was envisioned by the Agency at the time the current medical importance rankings list was published that it would periodically reassess the rankings to align with contemporary science and current human clinical practices. To that end, this paper describes a potential revised process for ranking antimicrobial drugs according to their relative importance in human medicine, potential revised criteria to determine the medical importance rankings, and the list of antimicrobial drug medical importance rankings that would result if those criteria were to be used. Disclaimer: This concept paper is for discussion purposes only. The intent of this concept paper is to obtain public comment and early input on a potential approach to consider the human medical importance of antimicrobial drugs when assessing and managing antimicrobial resistance risks associated with the use of antimicrobial drugs in animals. This concept paper does not contain recommendations and does not constitute draft or final guidance by the Food and Drug Administration. It should not be used for any purpose other than to facilitate public comment.

  • In Vitro Activity of Lefamulin Against Contemporary Staphylococcus Aureus Isolates from Patients in Europe (SENTRY 2016)
    P1823 In vitro activity of lefamulin against contemporary Staphylococcus aureus isolates from patients in Europe (SENTRY 2016) Susanne Paukner*1, Robert Flamm2, Rodrigo E. Mendes2, Steve Gelone3, Helio S. Sader2 1Nabriva Therapeutics GmbH, Vienna, Austria, 2JMI Laboratories, North Liberty, United States, 3Nabriva Therapeutics Inc., King of Prussia, United States Background: Lefamulin is the first semi-synthetic pleuromutilin antibiotic for IV and oral treatment of community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI). Lefamulin specifically inhibits bacterial protein translation by binding to the peptidyl transferase center (“induced fit”). Lefamulin is highly active in the lung in vivo and has recently completed a Phase 3 clinical trial for the treatment of CABP in adults showing non-inferiority to moxifloxacin (+/-linezolid). Staphylococcus aureus is a well-recognized cause of pneumonia, ABSSSI, and bloodstream infections (BSI), and management can be challenging due to high antibacterial resistance rates. This study investigated the activity of lefamulin and comparators against contemporary S. aureus isolates. Materials/methods: 550 unique S. aureus isolates were collected from hospitalised patients with BSI (50.0%), ABSSSI (30.0%), and pneumonia (20.0%) in 19 European countries (37 sites) during 2016 as part of the SENTRY Surveillance Program. Susceptibility testing was conducted using the CLSI broth microdilution method and susceptibility was interpreted per EUCAST 2017 breakpoint criteria. Results: Lefamulin was one of the most potent compounds tested, with 99.6% of all isolates inhibited at a concentration of ≤0.25 mg/L (MIC50/90 values of 0.06/0.12 mg/L). Susceptibility rates were >90% for clindamycin (MIC50/90, ≤0.25 mg/L/≤0.25 mg/L), doxycycline (MIC50/90, ≤0.06/0.25 mg/L), tigecycline (MIC50/90, ≤0.06/0.12 mg/L), vancomycin (MIC50/90, 0.5/1 mg/L), linezolid (MIC50/90, 1/1 mg/L) and ceftaroline (MIC50/90, 0.25/1 mg/L).
