We have brought cefiderocol to this Advisory Committee in order to gain the Committee’s insights and opinions, and the background package may not include all issues relevant to the final regulatory recommendation and instead is intended to focus on issues identified by the Agency for discussion by the Advisory Committee.

  • Antibacterial Prodrugs to Overcome Bacterial Resistance
    molecules Review Antibacterial Prodrugs to Overcome Bacterial Resistance Buthaina Jubeh , Zeinab Breijyeh and Rafik Karaman * Pharmaceutical Sciences Department, Faculty of Pharmacy, Al-Quds University, Jerusalem P.O. Box 20002, Palestine; [email protected] (B.J.); [email protected] (Z.B.) * Correspondence: [email protected] or rkaraman@staff.alquds.edu Academic Editor: Helen Osborn Received: 10 March 2020; Accepted: 26 March 2020; Published: 28 March 2020 Abstract: Bacterial resistance to present antibiotics is emerging at a high pace that makes the development of new treatments a must. At the same time, the development of novel antibiotics for resistant bacteria is a slow-paced process. Amid the massive need for new drug treatments to combat resistance, time and effort preserving approaches, like the prodrug approach, are most needed. Prodrugs are pharmacologically inactive entities of active drugs that undergo biotransformation before eliciting their pharmacological effects. A prodrug strategy can be used to revive drugs discarded due to a lack of appropriate pharmacokinetic and drug-like properties, or high host toxicity. A special advantage of the use of the prodrug approach in the era of bacterial resistance is targeting resistant bacteria by developing prodrugs that require bacterium-specific enzymes to release the active drug. In this article, we review the up-to-date implementation of prodrugs to develop medications that are active against drug-resistant bacteria. Keywords: prodrugs; biotransformation; targeting; β-lactam antibiotics; β-lactamases; pathogens; resistance 1. Introduction Nowadays, the issue of pathogens resistant to drugs and the urgent need for new compounds that are capable of eradicating these pathogens are well known and understood.

  • Beta-Lactam Allergy Evaluation and Empiric Therapy Guidance
    BETA-LACTAM ALLERGY: EVALUATION OF ALLERGY AND EMPIRIC ANTIBIOTIC SELECTION IN PATIENTS WITH A REPORTED ALLERGY Up to 15% of hospitalized patients report an allergy to penicillin. However, it is estimated that the label of a “penicillin allergy” is either inaccurate or not indicative of a true IgE-mediated reaction in up to 90% of patients. Often, penicillin “allergies” are miscategorized due to family history, non-allergic adverse reactions or confounders related to the patient’s underlying illness, or historical childhood events. Furthermore, IgE mediated penicillin allergy wanes over time, with 80% of patients penicillin-tolerant 10 years after the reported reaction. Being labelled as penicillin allergic results in dramatic shifts in antibiotic use, with more frequent use of vancomycin, fluoroquinolones, and clindamycin. These alternative agents, as compared to beta-lactam therapy, may be associated with increased toxicity (kidney injury with vancomycin), collateral damage (C. difficile infection with fluoroquinolones and clindamycin), clinical failure, increased risk of surgical site infection, increased length of stay, and mortality. The incorrect labelling of a sizable proportion of patients with a penicillin allergy adversely effects patient outcomes, which makes it imperative to identify mislabeled patients. While a detailed medication history by itself may identify erroneous “allergies”, it may not be effective in patients unable to provide a reliable history or with limited medical record at that institution. Penicillin skin testing (PST) with the PRE-PEN® skin test antigen, which is FDA indicated for the assessment of penicillin allergy along with Penicillin G, has a 97-99% negative predictive value. Approximately 95% of patients with a reported penicillin allergy have a negative penicillin skin test and can be safely prescribed penicillins.
