Clinical Research Bridging the Gap between Basic Science and Improved Human Health FASEB Clinical Research Subcommittee
What Is Clinical Research? • Research conducted on humans or human tissues that makes use of patient data. • Includes study of disease mechanisms, therapeutic interventions, epidemiology, and clinical trials. • Aimed at understanding human disease and improving human health. • Interaction between researchers and patient data is a key feature. Definitions of Clinical Research
Why is Clinical Research Important? • Enhances our understanding of human physiology and pathophysiology. • Translates basic research into medical care. • Informs and drives basic research. • Improves diagnostic tools and preventive care. • Improves human health!
What Can Clinical Research Accomplish? • Research in human physiology and pathophysiology translates basic research into knowledge of disease mechanisms and medical therapeutics. • Clinical trials establish safety and efficacy of new interventions. • Epidemiological and behavioral research identify high risk populations with potential to benefit from prevention, early detection, or therapeutic intervention. • Outcomes and health services research assess the health impact and cost-effectiveness of interventions.
Physiological Research • Carefully controlled studies in patients or normal subjects that are intended to understand basic physiologic mechanisms and their disruption in human disease. • Translation of basic research findings (in vitro and preclinical animal investigation) to human subjects to confirm the human relevance of proposed disease mechanisms, which will inform scientifically targeted medical therapeutics. • This work is usually done through General Clinical Research Centers (GCRC) and informs clinical trials.
Clinical Trials • Research that prospectively assigns human subjects to intervention and concurrent comparison/control groups to study the cause-and-effect relationship between a medical intervention and a health outcome (International Committee of Medical Journal Editors). http: //clinicaltrials. gov/ct/info/whatis#types
Clinical Trial Phases • Phase I trials: First-time test of intervention in a small group of people (20 -80) to evaluate safety, determine appropriate dosage, and identify side effects. • Phase II trials: Intervention given to a larger group (100 -300) to evaluate effectiveness and safety. • Phase III trials: Intervention given to large groups (1, 000 -3, 000) to confirm effectiveness, monitor side effects, compare to other treatments, and collect information that will allow it to be used safely. • Phase IV trials: Post marketing studies determine additional information including risks, benefits, and optimal use of an intervention.
Population Research • Epidemiology and behavioral research to identify high risk populations with potential to benefit from prevention, early detection, or intervention of established disease processes. • Outcomes and health services research to assess the health impact and cost-effectiveness of an effective intervention in a population or community setting.

Linking HIV to AIDS • Basic research into DNA, viruses, and retroviruses paved the way for the identification of the first human retrovirus in cancer patients. • Clinical studies showed that cancer-causing retroviruses exert similar effects to AIDS on the human immune system. • This helped scientists to identify HIV, a retrovirus in the same family as the cancer-causing retroviruses, as the one responsible for the development of AIDS. http: //opa. faseb. org/pdf/Finding_Chinks. pdf
Helping Newborns Breathe • Tens of thousands of babies died annually from a mysterious respiratory ailment. • Clinical investigators characterized the patients and studied infant respiration and human lung physiology. • Separately, basic studies of surface tension and pulmonary physiology allowed researchers to identify and characterize pulmonary surfactant. • With this information in mind, clinical and basic scientists determined that the deaths were due to a lack of surfactant, which caused the alveoli, or air sacs in the lungs, to collapse. • Treatments were then developed in the lab and tested in and applied to patients with great clinical success. http: //opa. faseb. org/pdf/babies_bubbles. pdf
Combating Breast Cancer • Basic research findings demonstrated the anti-tumor effects of tamoxifen in lab animals. • Clinical researchers showed that tamoxifen shrank breast tumors in afflicted women and reduced the risk of tumor recurrence. • Clinical researchers also demonstrated that healthy women treated with tamoxifen were less likely to develop breast cancer. • Tamoxifen is now widely used as a breast cancer treatment and preventive. http: //opa. faseb. org/pdf/Breast_Cancer_Breakthru. pdf

How is Clinical Research Regulated? • Office of Human Research Protections – Protects the rights, welfare, and well-being of subjects involved in research conducted or supported by the Department of Health and Human Services. • Food and Drug Administration – Regulates the approval process and assures the safety, efficacy, and security of drugs, biological products, medical devices. • Local Institutional Review Boards – Conducts initial review of research proposals. – Ensures participants are not exposed to unreasonable risks and that they give informed consent. – Conducts continuing review of approved research to ensure that human -subjects protections remain in force.
Challenges Faced By Clinical Researchers • Difficulty balancing patient care and research responsibilities. • Expensive medical training; lower salaries compared to private clinicians. • Long training time compared to medical school peers. • Burdensome regulations and paperwork. • Insufficient mentoring due to competing pressures. • Low success rate for clinical R 01 s.
Addressing the Challenges • Assess clinical research career development awards to optimize retention of clinical researchers. • Promote effective mentoring by senior clinical researchers. • Implement loan forgiveness programs to boost retention in the research track. • Streamline, standardize, and simplify regulatory requirements. • Include reasonable “protected time” requirements in grants to ensure sufficient time for research. • Ensure adequate representation of clinical researchers on review panels for clinical research grants.
