BioCardia Announces Positive Preclinical Results Supporting Investigational New Drug Application for Anti-Inflammatory Cell Therapy in Heart Failure
May 05, 2020
Plans IND Submission for Same Cells to Treat COVID-19 Induced Acute Respiratory Distress Syndrome
SAN CARLOS, Calif. – BioCardia®, Inc. [Nasdaq: BCDA], a leader in the development of comprehensive solutions for cardiovascular regenerative therapies, today announced data from a recent animal study performed by the Company that demonstrate meaningful improvements in heart function for subjects treated with its allogenic (from another donor, or “off the shelf”) neurokinin 1 receptor positive mesenchymal stem cell (NK1R+ MSC) program for heart failure, known as CardiALLO™. In addition, the Company is planning further exploration and discussion with the U.S. Food and Drug Administration (FDA) on the use of its allogenic cells for COVID-19 related Acute Respiratory Distress Syndrome (ARDS).
In the 26 animals treated with both low dose and high dose NK1R+ MSC, echocardiographic measures of cardiac ejection fraction, fractional shortening and cardiac outflow were meaningfully improved, with all three measures being statistically significant for both dosage levels over control animals.
The CardiALLO cell therapy is being developed initially to treat heart failure patients whose cells do not qualify for its lead autologous cell therapy, CardiAMP® (BCDA-01).
BioCardia Chief Scientific Officer Ian McNiece, PhD, said, “In light of these positive data on our allogenic NK1R+ MSC therapy, we expect to meet our internal timeline to complete our submission to the FDA for our first indication for CardiALLO, and potentially receive IND acceptance by the end of the second quarter. The MSCs that were studied are subtypes of MSC that we have delivered previously in our co-sponsored trials, which we believe have enhanced potency over MSC generated from unselected bone marrow cells. We look forward to seeing additional data from this animal study that are currently being analyzed, including histology and pathology of the heart and lungs.”
COVID-19 Induced Acute Respiratory Distress Syndrome (ARDS) Exploration
The Company also intends to submit an IND for the use of its NK1R+ MSC delivered via intravenous (IV) infusion for Acute Respiratory Distress Syndrome (ARDS) caused by COVID-19.
Based on preliminary clinical reports on COVID-19, respiratory failure complicated by ARDs is the leading cause of death for COVID-19 patients.1 ARDS is a type of respiratory failure characterized by the rapid onset of widespread inflammation in the lungs.
The anti-inflammatory effects of MSC have been well-documented and MSC have been shown to reduce inflammation and injury in models of lung disease.2 The specific MSCs used in BioCardia’s allogenic cell therapy are expanded from cells selected for the presence of the NK1 receptor, which is known to bind to substance P, an important neuropeptide associated with inflammation throughout the body and a primary mediator of inflammation in the airways.3,4
“Our NK1R+ allogenic MSC may have more potential than other MSC approaches being advanced today due to their interaction with Substance P,” said BioCardia CEO Peter Altman, PhD. “This COVID-19 related work will be the Company’s first clinical investigation outside of the cardiac space and our first exploring therapy for the lung. A recent patent publication (US 2020/0101113 A1) shows that BioCardia has long intended for these remarkable reparative cells to be targeted for respiratory disorders, in addition to cardiovascular disease. Addressing inflammation in the lungs is an important contribution we may be able to make using our NK1R+ allogenic MSC therapy.”
The Company’s allogenic cells are expected to be manufactured at BioCardia’s clinical stage cell manufacturing facility in San Carlos, California.
BioCardia, Inc., headquartered in San Carlos, California, is developing regenerative biologic therapies to treat cardiovascular disease. CardiAMP and CardiALLO™ cell therapies are the Company’s biotherapeutic product candidates in clinical development. The Company's approved products include the Helix™ transendocardial delivery system and its steerable guide and sheath catheter portfolio. BioCardia also partners with other biotherapeutic companies to provide its Helix System and clinical support to their programs studying therapies for the treatment of heart failure, chronic myocardial ischemia and acute myocardial infarction.
