Karen Bush

Following postdoctoral work, I joined the Squibb Institute for Medical Research in New Jersey and began studying beta-lactamases, the enzymes in pathogenic bacteria that are the major cause for resistance to penicillins and other beta-lactam antibiotics. While in the pharmaceutical industry (Squibb; Lederle/Wyeth; Johnson & Johnson), my scientific teams identified and/or developed the antibiotics aztreonam (Azactam®), piperacillin-tazobactam (Zosyn®), levofloxacin (Levaquin®), doripenem (Doribax®), and the anti-MRSA cephalosporin ceftobiprole (Zeftera®). My laboratory published studies examining the mechanism of action of penicillin-binding proteins (PBPs), the role of mutant PBPs in antibiotic resistance, and the interactions of various beta-lactamases with the beta-lactam antibiotics. I have authored a number of review articles that have established one of the most commonly used beta-lactamase nomenclature schemes. At Lederle and as the head of the Antimicrobial Drug Discovery Research team at J&J, I led the development of a number of high-throughput screening assays that identified novel inhibitors of bacterial enzymes. My teams also worked closely with medicinal chemists to discover novel monobactams, carbapenems, oxazolidinones, and topoisomerase inhibitors, resulting in six drugs that entered human clinical trials.


My current laboratory has focused on characterizing resistance mechanisms to beta-lactam antibiotics in enteric bacteria. Studies from my lab have alerted health care facilities in the greater Indianapolis area to the need for increased infection control to minimize the risk from carbapenem-resistant Enterobacteriaceae ("CRE"); these pathogens have been deemed by the CDC to pose an Urgent Threat to the health care community. My lab is also collaborating with several pharmaceutical companies to characterize the antibacterial activity of new investigational drugs against these resistant bacteria, providing information that is shared with the FDA in the drug approval process. Two of the agents tested, Zerbaxa® and Avycaz® have recently gained FDA approval. During these studies, we have identified unusual resistance characteristics to some of these new agents.

Richard Bax, MBBS

Richard is a key TranScrip expert in Infectious Diseases and has been involved in many clinical development programmes and regulatory submissions. He has over 38 years of industry experience, including working for Glaxo, Lilly and Astra Zeneca and has developed many antibiotics and antivirals.


Richard was VP at SmithKline Beecham from 1991-1999, working in London and Philadelphia, in charge of Global Anti-infective Clinical Development, resulting in over 15 successful NDAs/MAAs and launches including Famvir/penciclovir, Bactroban and Augmentin BD. Between 2000 and 2003, Richard was Chief Scientist to Biosyn, a microbicide company based in Philadelphia. He subsequently joined Chiron as VP and Clinical Director Europe. He was involved in the set-up of the EU part of the company and the successful MAA of Cubicin. He left over two years later when Novartis absorbed Chiron. In May 2007 he joined Viropharma as VP Clinical Director Europe and was involved in the setup of the EU company and the EU transplant maribivir phase 3 studies.


Richard has been a member of various working parties of the BSAC, ESCMID, European Union Grant Committee, EFPIA, IFPMA, EMA guidelines, Wellcome Trust, Medical Research Council, Surgical Infection Society (US) and the working party of the WHO on Bacterial Resistance as well as a consultant to the office of AIDS Research NIH US.


Richard has been a non-executive director of three start-up pharma companies.


Richard Bax is involved in guiding companies through early development, Phase I, II and III including Proof of Concept, to successful registration and to manage difficult strategic and scientific issues.


Richard Bax’s major activity is to bridge the gap between the company and the regulatory and reimbursement agencies.


Richard has over 100 publications, including nine book chapters and in peer reviewed journals including the BMJ, The Lancet, New England Journal of Medicine, Nature Medicine and Nature New Drugs on clinical trials, antibiotic resistance and prescribing, PK/PD predictors of outcome and the Pharmaceutical Industry.
