Drug Delivery

Gavin Jenkins, in his recent article for PittMed, reports on the work of McGowan Institute for Regenerative Medicine affiliated faculty member Louis Falo, Jr., MD, PhD, Professor and Chairman of the Department of Dermatology at the University of Pittsburgh School of Medicine.  Seven years ago, and inspired by the history of scratch vaccinations, Dr. Falo began researching microneedle array technology, which delivers medicine through the skin.  Afterall, our skin is our biggest organ, and our first line of defense against viruses and other pathogens we come across.

Overall antibiotic use was not curbed by giving physicians the results of biomarker tests in patients with suspected lower respiratory tract infections, according to findings from the Procalcitonin Antibiotic Consensus Trial (ProACT). The national, randomized clinical trial was coordinated by researchers at the University of Pittsburgh School of Medicine, and funded by the National Institute of General Medical Sciences, part of the National Institutes of Health (NIH). The results, published recently in the New England Journal of Medicine, were presented at the ATS 2018 International Conference in San Diego.  McGowan Institute for Regenerative Medicine affiliated faculty members Derek Angus, MD, MPH, and John Kellum, MD, are co-authors on the study.

Patents are a crucial element in moving academic research to the marketplace, where it can make a difference in the world. Without the economic protection a patent provides, there is little incentive for companies to invest time and risk large amounts of money to further develop early stage discoveries into technologies, products, or life-saving treatments.

A groundbreaking new study led by researchers from the University of Pittsburgh and UPMC—including McGowan Institute for Regenerative Medicine affiliated faculty member Marc Simon, MD, Associate Professor of Medicine, Director of Heart Failure Research, Medical Director of the Montefiore Clinical & Translational Research Center of the Clinical Translational Science Institute, and an Attending Physician in the Advanced Heart Failure and Cardiac Transplantation Section in the Heart and Vascular Institute of the University of Pittsburgh—has identified a new group of compounds that could have robust effects in treating pulmonary hypertension (PH), an enigmatic but sometimes fatal disease of the blood vessels of the lungs that currently has no cure. The findings, which were published in The Journal of Clinical Investigation, highlight the use of these drugs to alter vessel stiffness and its downstream control of metabolism, a link previously unknown for people suffering from the progressive disease.

SkinJect, Inc., a Pittsburgh-based company, today announced its completion of a license with the University of Pittsburgh to its novel, minimally invasive treatment for common forms of non-melanoma skin cancer, basal cell and squamous cell carcinoma. Two million new cases of basal cell cancer are reported each year in the United States, and more than half of all patients suffer a recurrence. The new product under development could dramatically change the way these skin cancers are treated.

Guidelines on lipid-lowering treatment for primary prevention of cardiovascular disease (CVD) are provided by the American College of Cardiology/American Heart Association (ACC/AHA) and the European Society of Cardiology (ESC). The recommendations for lipid-lowering treatment initiation from both guidelines are based on evidence from randomized clinical trials (RCTs) demonstrating the efficacy of statins for primary prevention of CVD. The trial evidence was translated by recommending initiation of treatment for adults with a predicted 10-year risk for CVD exceeding a given threshold.  However, global-risk algorithms were never used as an enrollment criterion for RCTs. Therefore, it has been argued that risk-based allocation of statins does not fully reflect the existing evidence. The degree of overlap and discrepancy between U.S. and European guidelines in light of available trial evidence remains unclear.  The Netherlands and U.S. authors from a recent paper published in JAMA Cardiology, aimed to compare recommendations from the latest ACC/AHA and ESC prevention guidelines with the evidence from 10 major primary prevention RCTs for statins.

New Processes Could Provide Personalized Pain Treatment

As reported by Karen Ferrick-Roman, Duquesne University Fall 2014 Magazine, pain costs Americans up to $635 billion each year for medical treatment and in lost productivity, says the Institute of Medicine of the National Academies. That hefty price tag is equivalent to the first 10 years of spending for homeland security, illustrating a nationwide problem of giant proportions.  Today, an estimated 116 million Americans live with chronic pain.

Renal Cell Carcinoma Focus of Clinical Trial

McGowan Institute for Regenerative Medicine affiliated faculty member Michael Lotze, PhD, professor of surgery and bioengineering, vice chair of research within the Department of Surgery, assistant vice chancellor in the six schools of the health sciences at Pitt, and director of strategic partnerships within the University of Pittsburgh Cancer Institute as well as the Catalyst Program within the recently funded Clinical and Translational Research Institute, is the principal investigator of an ongoing clinical trial focused on renal cell carcinoma (RCC).  The main goal of the research study is to determine whether treating renal cell cancer patients with the study drug, hydroxychloroquine, along with IL-2, a standard treatment of kidney cancer that has spread to other parts of the body, can make the cancer easier to kill and eliminate. Another goal is to see how the study drug affects the body’s immune cells which fight cancer cells.
