CLEVELAND

Athersys, Inc. (Nasdaq: ATHX) announced today that its partner, HEALIOS K.K. (Healios), has provided updates on its two clinical programs evaluating MultiStem® (invimestrocel, HLCM051) cell therapy, for which Healios has a license and is responsible for the development and commercialization of MultiStem for ischemic stroke and acute respiratory distress syndrome (ARDS) in Japan on an exclusive basis.

Healios reported that the last patient in its Phase 2/3 TREASURE study, evaluating MultiStem for the treatment of ischemic stroke, completed the 365-day follow-up visit. Additionally, Healios updated its progress in its discussions with the Pharmaceuticals and Medical Devices Agency (PMDA) regarding its MultiStem ARDS program and results from its ONE-BRIDGE study.

The last patient follow-up visit represents an important milestone in the TREASURE study, as it completes the collection of all patient data and enables the final validation of the data, analyses, and preparation of results by its contract research organization for unblinding and topline disclosures. Healios anticipates that it will receive the final topline results and make disclosures in May 2022.

TREASURE is a randomized, double-blind, placebo-controlled study in Japan evaluating the administration of MultiStem treatment within 18-36 hours after an ischemic stroke in over 200 patients with moderate to moderate-severe strokes. The TREASURE study, like its global counterpart, Athersys’ MASTERS-2 study, was designed based on the promising results from Athersys’ MASTERS-1 study for stroke patients treated with MultiStem therapy within 36 hours of the stroke. In the MASTERS-1 study, stroke patients receiving early MultiStem treatment had better outcomes than placebo patients at 90 days following treatment, and further improved outcomes at one year. Athersys expects that the TREASURE 90-day and one-year results would be strong indicators of the potential results from Athersys’ MASTERS-2 study.

“We are happy to report that Healios has completed the last patient follow-up visit and will soon disclose topline results from this important study,” commented Dr. John Harrington, Chief Scientific Officer of Athersys. “Furthermore, we are optimistic about the results and look forward to evaluating the data and better understanding its implications for our MASTERS-2 study.”

In addition, Healios has announced feedback received from the PMDA after recent consultation meetings to obtain guidance and advice pertaining to its application for MultiStem approval for ARDS, an orphan regenerative medicine program, on the basis of its Phase 2 ONE-BRIDGE study. The ONE-BRIDGE clinical trial was designed as a 30-patient, open label study, and demonstrated promising impact from MultiStem treatment on ventilator free days (VFD) and mortality. While the PMDA did not disagree with the efficacy and safety conclusions of the ONE-BRIDGE study, the PMDA advised Healios that additional supporting data is necessary for application for approval of MultiStem treatment for the ARDS indication. As a result of the guidance from the PMDA, Healios does not currently plan to apply for approval in Q2 2022. Healios will continue discussions with PMDA and work toward early application, and while it is undetermined at this time, it is expected that the application for approval is unlikely to take place in the current fiscal year.

Athersys is currently conducting its Phase 2/3 MACOVIA study, evaluating MultiStem treatment for ARDS patients, which includes patients diagnosed with ARDS due to COVID-19. The Company recently announced FDA approval to use product manufactured with its next generation bioreactor-based platform in the MACOVIA study.

Athersys continues to believe that MultiStem treatment has potential to have a substantial, positive impact on ARDS patients based on favorable data from its own double-blind, placebo-controlled Phase 1/2 MUST-ARDS study and strong supporting data from the Healios ONE-BRIDGE study. For example, on a combined basis, MultiStem-treated subjects had, on average, 5.5 more VFD in the first 28-days following diagnosis than non-treated subjects (with a p-value = 0.07) and, on a median basis, 10.5 more VFD during the 28-day period. Further, there was also strong evidence of a favorable impact from treatment on mortality and quality of life metrics. Athersys plans to work closely with Healios to build the supporting data necessary to apply for approval in Japan, including exploring the possibility of using certain MACOVIA clinical data.

“We congratulate Healios for achieving this important milestone in the TREASURE study and look forward to the topline results in May,” said Mr. Dan Camardo, Chief Executive Officer of Athersys. “We also look forward to continuing our work with Healios to advance the ARDS program in Japan. This is a very exciting time for both companies, and we remain committed to our partnership with Healios to work toward bringing MultiStem to market in Japan and eventually to the U.S. and other regions.”

About Ischemic Stroke

Stroke represents an area where the clinical need is particularly significant, since it is a leading cause of death and serious disability worldwide, with a substantially impaired quality of life for many stroke victims. Currently, there are nearly 17 million people who suffer a stroke globally and more than two million stroke victims each year in the United States, Europe and Japan, combined. Ischemic strokes, which represent the most common form of stroke, are caused by a blockage of blood flow in the brain that cuts off the supply of oxygen and nutrients and can result in long-term or permanent disability due to neurological damage. Unfortunately, current therapeutic options for ischemic stroke victims are limited, since the only available treatments, administration of the clot dissolving agent tPA, or “thrombolytic,” or surgical intervention to remove the clot, must be conducted within several hours of the occurrence of the stroke. As a consequence of this limited time window, only a small percentage of stroke victims are treated with the currently available therapy—most simply receive supportive or “palliative” care. The long-term costs of stroke are substantial, with many patients requiring extended hospitalization, extended physical therapy or rehabilitation (for those patients that are capable of entering such programs), and many require long-term institutional or family care.

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 MultiStem cell therapy toward commercialization.
