Clinical interests incllude:

* Pulmonary Physiology

* Cellular and Molecular Biology

* Regenerative Medicine


Contributions include (1) novel studies into the pathophysiology of equine asthma, (2) development of rigorous methods of assessing pulmonary function in animals, (3) development of novel non-surgical treatments for human emphysema, (4) elucidation of molecular mechanisms controlling lung regeneration, and (5) development of companion animal disease models, specifically for advancement of research into roles for extracellular vesicles in disease pathogenesis and therapeutic factors.

Dr. Hoffman has extensive experience, publications (~100), and patents (4) concerning novel methods of evaluation or therapies in spontaneous and experimental disease models in large animals. He also has ~15 yrs experience specifically in the development of preclinical large animal models in accordance with Good Laboratory Practices (GLP), including as PI/PD in a current study funded by NIH (RO1-HL112987-01A1) “Autologous Lung Derived Mesenchymal Stromal Cell Therapy for Emphysema”. Importantly this active study includes GLP-like pre-clinical studies in a large animal (sheep) model of emphysema followed by the first-in-human Phase 1 investigation of autologous LMSCs therapy for advanced emphysema in years 4-5, the latter under the direction of Edward P. Ingenito MD, PhD (PD/PI, Brigham and Womens Hospital).

Previously Drs. Hoffman and Ingenito developed major advances in human emphysema therapy, specifically non-surgical methods for lung volume reduction which are currently in Phase III again successfully linking pre-clinical large animal models with human studies. In addition, Dr. Hoffman’s laboratory serves as a Regenerative Medicine / Stem Cell core and project leader on several studies involving canine, feline, and avian species funded by a variety of Foundations and industry partners.

These multifaceted experiences have given the PD/PI the experience to lead multi-disciplinary projects involving stem cell implantations, bioengineering technologies, large animal experimental or spontaneous models, cell-molecular biology, biomarker analyses, clinical trial design, and FDA (GLP, GCP, GMP) compliance.
