The Pathway from Fundamental Discovery and Translational Medicine to Global Health Julio Licinio John Curtin School of Medical Research The Australian National University
Smallpox • V. major: more serious disease – mortality: 30–35% • V. minor: milder form of disease: kills 1% • Long-term complications of V. major infection: • characteristic scars, commonly on face (65–85%) • Blindness: from corneal ulceration and scarring • Limb deformities due to arthritis and osteomyelitis • Emerged in human populations about 10,000 BC • Earliest physical evidence of smallpox: pustular rash on the mummified body of Ramses V, Pharaoh of Egypt, who died in 1157 BC.
Smallpox • 18th century: killed 400,000 Europeans per year (including five reigning monarchs) • Was responsible for a third of all blindness. • Of all those infected, 20–60%—and over 80% of infected children—died from the disease. • 20th century alone: 300–500 million deaths • Early 1950’s: 50 million in the world per year. • 1967: (WHO) 15 million people contracted the disease and that two million died in that year.
Variola virus • Genus Orthopoxvirus • Family Poxviridae • Subfamily chordopoxvirinae. • Large brick-shaped virus measuring approximately 302 to 350 nanometers by 244 to 270 nm • Single linear double stranded DNA genome • 186 kilobase pairs (kbp) in size containing a hairpin loop at each end. • Unique among DNA viruses in that they replicate in the cytoplasm of the cell rather than in the nucleus.
Smallpox • Africa – Europe – Asia – Americas – Australia • Japan: epidemic of 735-737 killed 1/3 of population • Decimated native America empires: 80-90% death • Australia: introduced in 1789 and again in 1829 • Devastation among aborigines • Died out on both occasions • Only continent without endemic smallpox • Successful vaccination campaigns: 19th & 20th centuries • WHO certified the eradication of smallpox in 1980 • Only human infectious disease to have been eradicated
Smallpox vaccination • Live virus • Smallpox virus • Used for centuries in China and Turkey • Dangerous: • Person gets sick • Is infectious • Cowpox virus: • No major illness • Live vaccinia virus • PROCESS STARTED 14 May 1796 • ENDED 8 May 1980 Professor Frank Fenner Chairman, Global Commission for Certification of Smallpox Eradication
Accelerating translation • Moving away from a cottage industry of individual efforts • To a systematic, cross-disciplinary effort • Instead of being a side-activity • TM must become a bona-fide academic discipline in its own right • Process analogous to pharmacology • Drugs used by different specialties for centuries • An organized discipline of pharmacology led to enormous progress in therapeutics • An organized discipline of TM should likewise lead to enormous progress in translation
Creation of a new discipline • Body of work • Development of specific methods and approaches • Workforce development • Community engagement • Academic community • Community at large
TM as Academic Discipline • Development of specific methods and approaches (creative infrastructure that nurtures growth and progress). For translational medicine, this consists of the following: • Novel translational methods. This involves cross disciplinary innovation with contributions from the following non-healthcare academic areas: • Architecture: city and housing planning guided by translational health outcomes • Population health and epidemiology: applying genomics to population health and epidemiology to develop and validate in large cohorts novel translational approaches towards personalised medicine. • Chemistry: translational chemistry
TM as Academic Discipline • Mathematics: novel approaches towards modelling and data analysis. • Engineering: translational biomedical engineering. • Physics: novel robotics and imaging capacities. • Law: new legal approaches to translational issues. • Philosophy: bioethics approaches to new technologies, such as large scale genomics. • Sociology and anthropology: approaches to include minority, indigenous and underrepresented rural and economically disadvantaged communities in research in a manner that is inclusive and participatory, but not coercive. • Earth sciences: the impact of climate change on health.
TM as Academic Discipline • Asia and Pacific studies: approaches to global health outcomes • Arts and communication sciences: novel outreach strategies • Translational cores that facilitate the work developed in the areas listed above • Research ethics, research design, and data analysis: Translational protocols must be ethical, of sound design, and interpretable • Informatics capacity to support TM within institutions and for cross-institutional collaboration on compatible platforms • Translational clinical research spaces
TM as Academic Discipline • Creation of a specialized workforce that did not exist before. • Novel curricula • Courses • Postgraduate training programs • Dedicated career development • Clinical programs that incorporate translational medicine, including the offering of dual degrees, one of them being in translational medicine
TM as Academic Discipline • Community engagement. Two levels: • Engagement within the scientific community. • International programs. • Specialized journals. • Scientific meetings. • Professional outreach programs to promote awareness and cross-disciplinary outreach and collaboration. • Engagement with the community at large. • Government. • Business communities. • Foundations and other philanthropic bodies. • The public at large.
TM as an Academic Discipline • Development of a specific body of knowledge • Vocabulary • Jargon • Ontogenies • Databases
A conceptually novel structure for TM as an academic discipline We have created a new conceptual framework for translational medicine, in 6 steps, Translation zero (Tzero) through Translation 5 (T5)
T0 (T zero) • Refers to the fundamental process of discovery, which is sometimes forgotten in the discussion of translational science • Translation cannot be a pipeline only, or a bridge from nowhere • It is not the case that all fundamental discovery has occurred and if we bring to the clinic all the advances of recent years, disease will be conquered • Much fundamental discovery work still needs to be done so that proper translation can occur • One could have the best translation pipeline, but without translatable new fundamental science such pipeline becomes meaningless • This step is also critical if we are to distinguish translational science from purely applied science or from commercialisation.
T1 • This refers to the now "classical" step of bench to bedside – first in human studies
T2 • This refers to the now "classical" step of research from bedside to clinical care - clinical trials studies for example are in this domain
T3 • This term has been emerging but needs further definition • This could be best defined as translation of new evidence into health care guidelines and health policy
T4 • Defined as research on outcomes assessment of translation • Once translation occurs from T0 to T3, from novel fundamental discovery to health policy, the outcomes of such changes in practice need to be meticulously and critically evaluated • Not all new guidelines and policies will work out • Careful research is needed to determine what works out and what does not in order to guide the healthcare of the future
T5 = Global Health • Global implementation of new guidelines that emerge as the outcome of translation after research at the T4 level. • Further validates effectiveness and utility. • An example of T5 would be the worldwide eradication of smallpox: • After all steps of translation listed above occurred in terms of smallpox vaccine development and testing: • Initial concept (T0) • First in human (T1) • Clinical trials (T2) • After the vaccine's effectiveness became health policy in many countries (T3) • And it was systematically demonstrated to be safe and effective (T4) • A concerted global effort led to the final eradication of the disease (T5)
TM: Summary • TM must evolve away from isolated efforts in academic silos to become an endeavor that in increasingly: • Systematic • Academically rigorous • Cross-disciplinary • Cross-institutional • Cross-national THIS CONFERENCE WAS SPECIFICALLY DESIGNED FROM AN INITIAL PLAN BY JULIO LICINIO AND STEFAN BORNSTEIN TO JUMP START SUCH CROSS-NATIONAL EFFORTS • The German-Australian Institute for Translational Medicine (GAITM) • Making translational medicine a bona-fide academic discipline • This conference will be instrumental in establishing Translational Medicine as an internationally recognized academic discipline • Welcome to The John Curtin School of Medical Research, to The Australian National University, to Canberra and to Australia!
