Dr. Abraham received the BS (Psychiatric Nursing; 1975-1979) from Leuven University College (Leuven, Belgium), followed by the MS (Psychiatric-Mental Health Nursing; 1979-1982) and the PhD (Clinical Research; 1980-1984) from the University of Michigan (Ann Arbor, MI). He also completed execuctive education programs in Pharmaceutical Medicine (2001-2003) at the University of Basel (Basel, Switzerland), and in Entrepreneurship and Innovation in the Life Sciences (2011-2012) at the Vlerick Business School (Leuven/Gent, Belgium).
He has served on the faculty of Case Western Reserve University (Cleveland, OH), University of Virginia (Charlottesville, VA), and (part-time) Katholieke Universiteit Leuven (Leuven, Belgium); and as visiting professor at Universiteit Maastricht (Maastricht, The Netherlands), University of Florida (Gainesville, FL), Rijksuniversiteit Groningen (Groningen, The Netherlands), University of Pennsylvania (Philadelphia, PA), and Chang Gung University (Kwei-Shan Tao-Yuan, Taiwan). He came to the University of Arizona on a part-time basis in 2007, joining the faculty on a full-time basis in late 2012.
His research and innovation work has been funded continuously since 1984 by governmental agencies, foundations, and corporations worldwide. He has served in the US as appointed and ad hoc reviewer for the NIH, the NIMH, and the AHRQ; in Europe for EU health research funding programs; and in Japan, The Netherlands, and Catalunya (Spain) for national health research funding agencies. He currently serves as expert adviser to the Innovative Medicines Initiative, a joint undertaking of the European Union and the biopharmaceutical industry to stimulate innovation in human therapeutics.
Ivo Abraham, PhD, RN, a nurse by profession and an outcomes and effectiveness researcher by trade, is a clinician-methodologist interested in various aspects of how variations in treatments, from molecules to models of care, are associated with variations in clinical, patient-centric, and economic outcomes at the patient and population levels. As a methodologist, his work spans several therapeutic domains, however all tied together by common methodological and analytical threads – drawing often upon those from disciplines other than the health sciences. A large part of his work has been in supportive and curative cancer care, spanning both solid and hematological malignancies.
For the past 15+ years, Dr. Abraham’s research has focused mainly on “real-world evidence” on how variability in (drug-centric) treatment regimens is associated with variability in clinical and patient-centric outcomes – including how this translates into economic outcomes. Instead of merely evaluating effectiveness (“does the treatment work?”), the work of his research group addresses the equally important questions of “when does the treatment work, and when not?”, “what influences whether the treatment works, and what not?”, “why does the treatment work in some patients but not in others?”, “why does the treatment work with some clinicians but not with others?”, “why is the treatment tolerated by some patients but not by others?”, “how much of patient outcomes is related to patient vs. clinician or treatment center” – and, eventually, “is this economically worth it and sustainable, and why or why not.” In this process, his group uses a comprehensive framework of treatment patterns and outcomes assessment, vulnerability profiling, hierarchical modeling, (non-)responder analysis, pharmacovigilance, and economic evaluation. By integrating methods and analytics from other disciplines, his group also tries to establish alternate pathways of inferring causality.
Taking a scientific rather than polemic tack, he has been the scientific lead on several international real-world studies on the clinical and economic outcomes of supportive cancer care with growth factors (erythropoiesis-stimulating agents and granulocyte-colony stimulating factors). Working initially in Europe but now also in the US, this work has since extended into the clinical effectiveness and safety of biosimilar versions of originator growth factors, as patents for these products are expiring. His group was the first to demonstrate the economic benefits that can achieved by using quality biosimilars; and, importantly, how the cost savings associated with biosimilar use can be reallocated to purchase more curative cancer care (e.g., with targeted agents) in a budget-neutral fashion.
Another area of impact research concerns patient adherence to oral anticancer agents. Building on emerging studies on non-adherence to these agents in general, he and his colleagues demonstrated that, despite the high efficacy of imatinib in the management of chronic myeloid leukemia, (a perhaps surprising) one-third of patients admitted to occasional non-adherence. Importantly, they were able to associate non-adherence, as measured by pill count, with incomplete cytogenetic response and (composite) suboptimal response. The group is now looking into mathematically modeling gradients of medication adherence and the probability of achieving hematological, cytogenetic, and molecular response. In an effort to support clinical practice, the group is also examining whether a single-item query or rating of adherence might predict treatment response.
On the economic side, and in addition to its work on biosimilar savings, his group is examining new concepts and methods for the economic evaluation of increasingly more costly cancer treatments. They aim to abandon the limitations of absolute or quality-adjusted gains survival benefits and the use of non-empirical value thresholds for treatment and reimbursement decisions.
Frustrated by the abundance of evidence-based guidelines but clinicians’ limited adoption of these guidelines, his group has started examining how practicing in accordance with evidence-based guidelines is directly associated with patient outcomes. This line of work involves the development of methods for quantifying patient-level guideline-congruent care and ways of associating these with clinical outcomes. Relatedly, though an early advocate of meta-analytic methods, Dr. Abraham has become concerned about imputed biases that cannot be detected by currently available methods, especially as they relate to scope specification, interpretation, and (polemic or economic rather than scientific) positions.
