Research Summary

Mark Gladwin, MD has a long history of leadership of translational projects and programs. He currently serves as co-PI on a new multi-center clinical trial of Riociguat to treat patients with sickle cell disease and pulmonary hypertension and has served as PI on the multi-center clinical trials Walk-PHASST (Pulmonary Hypertension and Sickle Sildenafil Therapy Trial) and DeNOVO (Delivery of NO for Vaso-Occlusive pain crisis in sickle cell disease). He has served as a principal or associate investigator on more than 50 human subjects protocols and has held 10 FDA INDs for the use of investigational therapeutic medications, including inhaled, intravenous and oral preparations of sodium nitrite, carbon monoxide, L-NMMA, acetylcholine, riociguat, and sildenafil. Dr. Gladwin’s basic and translational research has led to the development and licensing of intravenous and inhaled nitrite as a human therapeutic, with the recent completion of animal toxicology, GMP formulations, and phase Ia and Ib clinical trials. Phase II trials of inhaled nitrite are now underway. 

A central passion of Dr. Gladwin’s is to train the next generation of physicians and scientists in basic and translational research. He has a demonstrated commitment to training and education, and has trained students at many levels including pre-medical students participating yearly in the NIH Intramural Research Training Program, the Howard Hughes young investigator program, the Intramural Clinical Research Training Program, and many successful academic physician-scientists coming out of Pulmonary, Critical Care, Surgical, and Hematology Fellowship Programs. He has been very successful at mentoring these trainees to independent careers in academic medicine. Dr. Gladwin has mentored many to intramural funded faculty positions or extramural K or R awards. He has also mentored pre-doctoral students who have matriculated into both PhD and MD programs. Dr. Gladwin’s publications number well over 150 with current or past trainees as the first author. Dr. Gladwin is currently the PI of an NIH T32 training grant and previously directed another T32 while he was Division Chief of Pulmonary, Allergy and Critical Care Medicine at the University of Pittsburgh.
