Athersys Reports That Healios Has Completed Enrollment in the ONE-BRIDGE Study of MultiStem® for Acute Respiratory Distress Syndrome in Japan

March 31, 2021 Off By BusinessWire

Off-the-shelf stem cell therapy has potential to enhance recovery for ARDS patients

CLEVELAND–(BUSINESS WIRE)–$ATHX #ARDS–Athersys, Inc. (Nasdaq: ATHX) announced today that its partner HEALIOS K.K. (Healios) has completed enrollment in the ONE-BRIDGE study in Japan evaluating MultiStem^® (invimestrocel) in patients with acute respiratory distress syndrome (ARDS) caused by pneumonia.

The ONE-BRIDGE trial consists of two patient cohorts. With cohort 1, the objective is to demonstrate the safety and efficacy of MultiStem treatment for patients with pneumonia-induced ARDS. Cohort 1 was designed as a randomized, open-label study to enroll 30 patients. The primary efficacy endpoint is the number of ventilator-free days in the 28 days following the treatment allocation. Cohort 2 was designed to enroll five patients with COVID-19 induced ARDS with the objective to evaluate the safety of MultiStem treatment in these patients. Healios intends to analyze and evaluate the data after the follow-up period and will make further announcements, as appropriate.

In the United States, Athersys is conducting its own clinical study evaluating MultiStem cell therapy for the treatment of ARDS, the MACOVIA trial. This study includes patients with ARDS due to COVID-19 and other pathogens. The ARDS program was granted both Fast Track and Regenerative Medicine Advanced Therapy (RMAT) designations from the United States Food and Drug Administration.

About ARDS

Acute respiratory distress syndrome (ARDS) is a serious immunological and inflammatory condition characterized by widespread inflammation in the lungs. ARDS can be triggered by COVID-19, pneumonia, sepsis, trauma or other events and represents a major cause of morbidity and mortality in the critical care setting. It has significant implications, as it prolongs intensive care unit (ICU) and hospital stays and requires convalescence in the hospital and rehabilitation. There are limited interventions and no effective drug treatments for ARDS, making it an area of high unmet clinical need with high treatment costs. Given these high treatment costs, a successful cell therapy could be expected to generate significant savings for the healthcare system by reducing days on a ventilator and in the ICU and importantly, could reduce mortality and improve quality of life for those suffering from the condition.

About MultiStem^®

MultiStem^® cell therapy (invimestrocel) is a patented regenerative medicine product candidate in clinical development that has shown the ability to promote tissue repair and healing in a variety of ways, such as through the production of therapeutic factors in response to signals of inflammation and tissue damage. MultiStem therapy’s potential for multidimensional therapeutic impact may distinguish it from traditional biopharmaceutical therapies focused on a single mechanism of benefit. MultiStem represents a unique “off-the-shelf” stem cell product candidate that can be manufactured in a scalable manner, may be stored for years in frozen form, and is administered without tissue matching or the need for immune suppression. Based upon favorable outcome data, its novel mechanisms of action, and favorable and consistent tolerability data in clinical studies, we believe that MultiStem therapy may provide a meaningful benefit to patients, including those suffering from serious diseases and conditions with unmet medical need.

About Athersys

Athersys is a biotechnology company engaged in the discovery and development of therapeutic product candidates designed to extend and enhance the quality of human life. The Company is developing its MultiStem^® cell therapy product, a patented, adult-derived “off-the-shelf” stem cell product, initially for disease indications in the neurological, inflammatory and immune, cardiovascular and other critical care indications and has several ongoing clinical trials evaluating this potential regenerative medicine product. Athersys has forged strategic partnerships and a broad network of collaborations to further advance the MultiStem cell therapy toward commercialization.

About Healios

Healios is Japan’s leading clinical stage biotechnology company harnessing the potential of stem cells for regenerative medicine. It aims to offer new therapies for patients suffering from diseases without effective treatment options. Healios is a pioneer in the development of regenerative medicines in Japan, where it has established a proprietary, gene-edited “universal donor” induced pluripotent stem cell (iPSC) line to develop next generation regenerative treatments in immuno-oncology, ophthalmology, liver diseases, and other areas of severe unmet medical need. Its near-term pipeline includes the somatic stem cell product HLCM051, which is currently being evaluated in Japan in Phase 2/3 and Phase 2 trials in ischemic stroke and acute respiratory distress syndrome (ARDS), respectively. Healios was established in 2011 and has been listed on the Tokyo Stock Exchange since 2015 (TSE Mothers: 4593). https://www.healios.co.jp/en/.
