Study summary

The objective of the present study is to establish the safety and efficacy of multiple administrations of Prochymal™(ex-vivo cultured human adult mesenchymal stem cells) in participants with moderate to severe chronic obstructive pulmonary disease (COPD).

Read the detailed description

COPD is currently the fourth leading cause of death in the United States. It is clear that there is a significant unmet medical need for safe and effective therapies to treat moderate to severe COPD. This patient population has a high mortality rate and requires frequent hospitalizations due to disease-related exacerbations. Based on severity distribution estimates, approximately 70% of all current COPD patient have either moderate or severe COPD. COPD has no known cure, thus current therapeutic intervention is aimed at providing relief of symptoms. Oxygen therapy is the only treatment that has been shown to improve survival. Smoking cessation has been shown to slow the rate of forced expiratory volume in 1 second (FEV1) decline and COPD progression. In general patient are treated with bronchodilators and inhaled corticosteroids, but again, these measures do not provide any significant benefit regarding disease progression or prognosis. The characteristics and biologic activity of Prochymal™, along with a good safety profile in human trials to date, suggest that Prochymal™ may be a good candidate for addressing this unmet medical need.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2008 to primary completion in Mar 2009, 11 months.

Of 118 industry-sponsored phase 2 interventional studies under Pulmonary Disease, Chronic Obstructive, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 20. This study's 11 months is below that.

Counting every sponsor, half of 165 studies reached it within 17 months; a quarter within 10 and three quarters within 31.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
