John Horton, MA, MB BChir, MRCGP, FFPM, President, Co-founder, Board Member. Principal, Tropical Projects, Hitchin, UK

John Horton is a physician with extensive experience in neglected tropical diseases. For the past 45 years, he has been involved in research into tropical diseases, specifically into chemotherapy, initially working at GlaxoSmithKline (and its predecessors) and for the past 25 years as an independent consultant, providing his expertise to drug and clinical development programs under the auspices of the WHO and more recently the Bill and Melinda Gates Foundation. While at GSK, he led the company’s tropical medicine development team and has a working knowledge of all aspects of drug development. More recently, his work has been focused on the development of public health initiatives for neglected diseases, including those caused by helminths. He was largely responsible for driving the development of albendazole for the treatment of cysticercosis and echinococcosis, as well as developing the scientific rationale for global eradication programs for soil transmitted nematodes and filariasis. As the global expert on albendazole, and with a unique insight into development of interventions for tropical diseases including cysticercosis, Dr. Horton is well qualified to analyse the toxicity of interventions, to design clinical studies and to evaluate how these fit within the regulatory framework. In addition, he has a good working knowledge of the drugs currently used within the field of neglected diseases and understands issues relating to drug/drug interactions, especially when considering drug development and clinical interventions. His involvement with oxfendazole predates the establishment of the Oxfendazole Development Group (ODG), initially working with the Hopkins/Peru team the initiated this development, and now uses his expertise as President of ODG.

After working on tropical parasitology at Michigan State University, he joined The Upjohn Company (Pharmacia – Pfizer-now Zoetis) in 1985. He remained at Pfizer until 2005, then joined the Institute of Parasitology at McGill University as Professor and Tier I Canada Research Chair. He served as Director of the Institute from 2007-2019, when he became Emeritus Professor. He was a Professor (20% appointment) in the School of Biological Sciences at Queen’s University – Belfast from 2019-2026. His work over the past 45+ years has focused on the discovery and development of antiparasitic drugs, on the pharmacology of these drugs, and on the molecular language of the host-parasite interface.
Tim earned national and international funding to support his research and received many awards. He has published > 240 peer-reviewed articles and book chapters, is on the editorial boards of 6 scientific journals and is a consultant for many pharmaceutical, government and non-government organizations. He is a Past-President of the American Association of Veterinary Parasitologists and is a member of the Executive Committee of the World Association for the Advancement of Veterinary Parasitology.
Robert H. Gilman, M.D., DTM&H, Co-founder, Board Member. Professor, Johns Hopkins University, Department of International Health. Johns Hopkins Bloomberg School of Public Health, Baltimore, MD; Investigative Professor, Universidad Peruana Cayetano Heredia, Lima, Peru Associate AB PRISMA, Lima, Peru
Dr. Gilman has worked in Peru for the last 30 years in collaboration with the Universidad Peruana Cayetano Heredia (UPCH) and the NGO AB PRISMA. There is a JHU-directed laboratory at the UPCH, as well as multiple population based sites including one at Iquitos in the Amazon jungle. The group in which he works has conducted studies under the auspices of NIH, USAID, IDRC, FDA, Welcome Trust, Gates Foundation and other international agencies and has been highly productive with more than 400 papers published in peer‑reviewed journals in the last 20 years. In addition to being a tenured professor at JHSPH, Dr. Gilman holds the position of Research Professor in the Department of Microbiology at UPCH. He resided in Peru for 18 years and now spends at least four months per year in Peru. His expertise in tropical diseases especially related to diarrhea and parasitic disease derives from an extensive history of work in diverse locations including Malaysia, Bangladesh and Peru. Importantly, he has worked on oxfendazole with the present group over several decades.
Javier A. Bustos, MD, MSc, MPH, PhD, Board Member. Associated Investigator at the Center for Global Health, Universidad Peruana Cayetano Heredia, Lima, Peru

After completing his medical degree at Universidad Peruana Cayetano Heredia, Javier Bustos obtained two Master degrees, one in Infectious Diseases Control at Universidad Peruana Cayetano Heredia and the second in Public Health at Johns Hopkins School of Public Health (JHSPH), as well as a PhD in the International Health Department (Global Disease Epidemiology and Control program) at JHSPH.
Over the last 25 years, this training has facilitated Dr. Bustos’ role as associate researcher in the Cysticercosis Working Group in Peru. His responsibilities extend from designing studies to monitoring ethics and regulatory-related issues in basic science studies as well as in clinical, preclinical, and epidemiological research studies. His work spans studies in animals (e.g., on the stages of T. solium cyst calcification) to human studies aimed at treatments to reduce the inflammatory sequelae for patients with calcified cysts. Having studied T. solium chemotherapy in both animals and human patients, Dr. Bustos is now a key part of two clinical trials for the use of oxfendazole in T. solium neurocysticercosis [U01-AI177191] and in Fasciola Hepatica [U01-AI155323].
Dr. Bustos has been member of the IRB of the US Naval Medical Research Center Detachment in Peru and served as a WHO consultant to conduct systematic reviews for the drafting of “WHO Diagnosis and Treatment Guidelines for Taenia solium Neurocysticercosis (NCC).” As result of his extensive research activity, Dr. Bustos has more than 60 peer-review publications.
