Phase-0/Microdosing Network description

The Phase-0/Microdosing Network is the organizer of the stakeholder meeting. It was created to share news and ideas relevant to the research and applications of these approaches and increase their impact in drug development. Members include clinicians, scientists, regulators, Pharma, Biotech, CROs, patient advocacy groups and other non-profit organizations with interest in the potential of these approaches to provide safer, faster, and cheaper, live human data for drug development decision-making. The network aims to use the collective inter-disciplinary knowledge and skills to establish a versatile and comprehensive appreciation of the potential of these approaches to address developmental needs. Specifically, the network considers AMS/PET/LC-MS/MS methodologies and the continuum of microdosing and other Phase-0 approaches are complementary, synergistic, and cost-effective investigational tools for first-in-human, including first-in-patient studies. The network welcomes and encourages discussion of the limitations of these approaches, as aims to clarify their role in current and future drug development and identify criteria for their effective application. The network was founded by Tal Burt, M.D., Graeme Young, Ph.D., and Le Vuong, Ph.D.

Tal Burt Picture

Tal Burt, M.D.

Founder,

President & CEO

Dr. Burt is a clinical research and drug development consultant. He received his medical degree at the University of Florence, Italy, and trained in psychiatry and clinical research at New York University, Harvard, and Columbia University. He is a board-certified psychiatrist with more than 20-year experience in all phases of clinical development and expertise in the early-phase, proof-of-concept (POC), and microdosing stages of clinical development. He has led clinical research programs of drugs and devices in academia and industry, leading him to appreciate the challenges of new treatment development, including the huge expenses, wastes, uncertainties and risks involved, and the considerable burden on public health and research ethics that ineffective translational and clinical research lead to. He worked with regulators (FDA, Japan PMDA, Singapore HAS, India DFA), industry, academic, and patient advocacy stakeholders to address these challenges and accelerate development of novel therapeutics. He has authored 45 peer-reviewed publications in clinical research and drug development including original drug development methodologies such as Intra-Target Microdosing (ITM), randomized-withdrawal designs, assessment of the impact of false-negatives on the productivity of treatment development, the first publications of Vagus Nerve Stimulation (VNS) in major depression, the first comprehensive review of Transcranial Magnetic Stimulation (TMS), and a textbook on Outcomes Measurement in Clinical Psychiatry.

Professor Rowland's research interests are in pharmacokinetics, particularly the development and application of physiologically-based models, the prediction of pharmacokinetic behavior in humans, and intestinal drug absorption. He is the author of over 300 scientific publications and is the co-author of the textbook - Clinical Pharmacokinetics: Concepts and Applications.

Yuichi Sugiyama

Yuichi Sugiyama, Ph.D.

Dr. Sugiyama has been the Head of Sugiyama Laboratory, RIKEN Innovation Ctr, RIKEN Research Cluster for Innovation, Yokohama, Japan since April 2012. He had been Professor, Dept of Molecular Pharmacokinetics at the Univ of Tokyo since 1991 until 2012. His work is internationally recognized by many awards, including the American Association of Pharmaceutical Scientists Distinguished Pharmaceutical Scientist Award in 2003, the International Pharmaceutical Federation (FIP) Hoest Madsen Medal in 2009, the Medal with Purple Ribbon, a Medal of Honor given by the Japanese Government in 2010, the BB Brodie Award from the American Society for Pharmacology and Experimental Therapeutics in 2012, the RT Williams Distinguished Scientific Achievement Award  from the International Society for the Study of Xenobiotics (ISSX) in 2013 and Rawls-Palmer Progress in Medicine Award from American Society for Clinical Pharmacology and Therapeutics in 2014. Dr. Sugiyama was listed as #1 scientist in 2007 for the number of citations he received in the preceding 10 years in the field of pharmacology and toxicology. He served as the chairman of Board of Pharmaceutical Sciences in FIP (2000-2004). He was also the president of both ISSX and the Japanese Society for Xenobiotic Metabolism and Disposition (2006-2007). He also led the Japanese government project on microdosing. The NEDO (New Energy and Industrial Technology Development Organization) project entitled “Establishment of Evolutional Drug development with the Use of Microdosing Clinical Trial” was adopted (2008-2011). In this project, the quantitative prediction method on ADME using modeling and simulation was applied to human to validate this methodology. That is, based on the in vitro data on metabolism, transport and binding with animal and human tissues, the drug concentration-time profiles in the plasma and target tissues such as liver and brain was predicted, and the validity of the predictions was investigated by using clinical studies under its microdose and therapeutic dose conditions. PET probes have been developed for specific transporters; for example, the effects of changes in OATP1B1 and MRP2 activity on systemic and hepatic exposure of some compounds were simulated using a physiologically-based pharmacokinetic (PBPK) model incorporating blood, liver (clearance and pharmacological target organ), and peripheral organs. Additionally, the microdose studies using unlabeled compounds only at low doses not only allowed estimation of the pharmacokinetic profiles of candidate drugs before clinical trials but also clarified the major factors dominating their pharmacokinetics when cassette doses of probe substrates were used in presence and absence of probe inhibitors. Such microdose studies should allow a quantitative understanding of the effects of genetic polymorphisms and drug-drug interaction of transporters on the pharmacokinetics of drugs and should open new avenues to drug development.
