Osiris Therapeutics, Inc. (NASDAQ:OSIR) announced the treatment of the first patients in a new Phase II clinical trial evaluating Prochymal, a mesenchymal stem cell (MSC) therapy, for moderate to severe Chronic Obstructive Pulmonary Disease (COPD). This trial marks the sixth indication for which Prochymal has been advanced into Phase II or later-stage clinical trials.
COPD, a form of lung disease characterized by limitation or obstruction of airflow in the airway, encompasses both emphysema and chronic bronchitis. COPD is the fourth leading cause of death in the U.S. with an estimated 12 million Americans diagnosed with the disease. COPD has no known cure, thus current therapeutic intervention is aimed at providing relief of symptoms. Preclinical and clinical data suggest that Prochymal's unique mechanism of action may provide a first-in-class treatment option with the ability to reverse the underlying disease.
"Our COPD program serves as another example of how quickly and efficiently we can now work towards developing this first-in-class stem cell therapy," said C. Randal Mills, Ph.D., President and Chief Executive Officer of Osiris Therapeutics. "With the early testing completed, the clinical development and regulatory pathways are significantly streamlined for future indications. This supports our strategy to seek initial approval for the world's first stem cell drug in relatively small underserved diseases, such as GvHD and resistant Crohn's disease, and promptly expand the technology to include blockbuster markets for which the technology also holds great promise."
"Studies that we and others have conducted provide convincing evidence that MSCs have the potential to be effective in addressing selected lung diseases, including COPD," said Daniel Weiss, M.D., Ph.D., Associate Professor of Medicine at the University of Vermont College of Medicine and an expert in research using stem cells to treat lung diseases. "These mesenchymal stem cells are particularly suited for treating pulmonary disease due to their inherent trafficking pathway through the lungs when delivered intravenously and their ability to remain in the lungs when inflammatory molecules are present. With their demonstrated ability to both reduce inflammation and reverse tissue damage, we have reason for optimism about Prochymal's use in this devastating disease."
A recent Osiris study evaluating Prochymal as a treatment for myocardial infarction demonstrated a statistically significant improvement in lung function as compared to placebo. Specifically, patients treated with Prochymal showed a 17 point improvement in FEV1 % predicted, a measure of pulmonary function, versus only a 6 point improvement in patients treated with placebo (p < 0.05). Prochymal has also demonstrated clinical benefit in trials evaluating patients with inflammatory conditions including graft-versus-host disease (GvHD) and Crohn's disease, both of which are in Phase III programs and have Food and Drug Administration (FDA) Fast Track status.
"This landmark study is very exciting for the entire field and we are honored to have been able to enroll and treat the first patients," said Charles Fogarty, M.D., Medical Director of Spartanburg Medical Research. "We look forward to the results of this trial, which may have long-term implications for improvements in disease progression and remodeling of the lung."
About the Phase II Chronic Obstructive Pulmonary Disease Trial
The Phase II trial will evaluate the safety and efficacy of Prochymal in conjunction with standard of care for improving pulmonary function in patients with moderate to severe COPD. The clinical trial is a double-blind, placebo-controlled study conducted at multiple sites with a target enrollment of 60 patients. Patients will be randomized to either Prochymal or placebo at a 1:1 ratio. Pulmonary function tests, exercise capability, and quality of life are some of the measurements being used to detect potential improvements in subjects treated with Prochymal. In addition, exacerbations and hospitalizations due to COPD will be monitored for both safety and efficacy. Patients will be evaluated over the course of two years following initial Prochymal or placebo infusion.
About Prochymal
Prochymal is a preparation of mesenchymal stem cells specially formulated for intravenous infusion. The stem cells are obtained from the bone marrow of healthy adult donors. Prochymal is currently being evaluated in three, double-blind, placebo controlled Phase III studies, including steroid refractory GvHD, acute GvHD, and Crohn's disease. Prochymal has been granted Fast Track status by FDA for all three of these indications. Prochymal also obtained Orphan Drug status by FDA and the European Medicines Agency for GvHD. FDA established the Fast Track program to accelerate the development of drugs that show promise for treating life-threatening conditions. Orphan Drug designation provides incentives to companies that develop drugs for underserved patient populations. Prochymal is also being studied in Phase II trials for the treatment of acute myocardial infarction, type 1 diabetes, and COPD. Additionally, the Department of Defense recently awarded Osiris a $224.7 million contract to develop Prochymal for acute radiation syndrome.
